- We’ve gotten maybe too good at fishing, and as a result we’ve completely transformed the oceans. So what can we do to make fishing more sustainable and still enjoy our fish and chips?

There is a easy solution. Turn 80% of the sea in protected Areas where all extracting of natural resources is banned and the ban is enforced.
Protected Areas are selected by habitat, spawning ground and travel routes of fishes.
This would cause the price of fish to rise and end up creating a huge black market. But if we spend enough fighting that black market, eventually fish will cost so much that the average person will stop buying it. Over time this would change cultural attitudes towards fish as being a luxury item, and keep consumption at relatively low levels, until new fish-producing technologies are created or the ocean recovers and fish become cheap again.
Or at least, that's how it would play out in countries where corruption isn't very common. We might instead end up buying cheap fish exported from China where they're paying off the regulators to fish in protected areas.
@@em-yz6rl You're pretty much right on the money on this.
Most regulations turn into black markets. Especially true about the China part.
I don't really want to pay more money for fish caught by those overseas to then be sold to me at a premium because my Government screwed with the economy.
There's a balance to be had, but good balances don't come from government.
Definitely eye rolled with the block chain idea
We need a law where anyone suggesting blockchain as a solution to anything is immediately hit with a brick.

A study must be done to find out which colour street light works best for species of drivers in different countries because red does not work universally.
I know you're joking but we can do something similar to street lights (not the traffic lights but the lights illuminating the road).
The current bright white or yellow lights have a big impact on local ecosystems, we might be able the colour and intensity to something that still illuminates the road for us but doesn't disrupt the environment.
Can you please talk more about the impact of mass fishing in the ocean and the impact of it on marine life?
I thought the fish scales would function as the QR code, though that would only work if you buy whole fosh and if the scales are unique enough on each fish.
Nice idea - but fish lose and regenerate scales all the time, so it's hard to find 2 scales on the same fish that tell the same story. Also, since all marketable fish stocks are social (i.e. harvestable) animals by definition, you'd have a whole crapload of fish in the same cohort with identical scale signatures.
You wouldn't literally put a QR code on the fish. They would be contained in batches.
@@samuelmiller8261 Yeah, but this could be a way to literally put ”QR codes” on each individual fish :) Though calling it QR codes is not accurate, it’s basically ”face recognition for fish”.
I like that most of comments are "just don't eat fish".
When it's something that you don't care about the solution is really obvious.
I actually found some "fish fingers" made from scorzonera (black salsify) that I like better than ones made from actual fish. They also make way less of a mess when you fry them.
You can't blame people for living in their protective bubbles. A huge part of the human population DEPEND on fish as a food source. See the human population IS the problem, there are just way too many. I like how everyone ignores the real problem and looks away from it too afraid to deal with it. At some point it will have to be dealt with and those won't be happy days.
@@huldu this is the kinda sht that keeps me up at night. Humanities most real existential threat is overpopulation. I really hope we can make this all work out.
@@huldu the human population is not the problem, the sustainability of our lifestyles is. we kill eight times more farmed land animals than there even are humans *every year*
fish farming and fishing is inefficient when we could just evenly distribute plant based foods. capitalism is the problem, not the human population
and if you still think human overpopulation is a problem then just dont have kids (and if u want a family and are capable of having one then adopt)
@@chickpeapeace no, exponential growth of the human population is. Even if we were able to live more sustainably we would expand our population faster than we realize, which has already happened. All it would do is buy us some more time. And a paltry amount at that. Its the elephant in the room that at best gets handwaved away by saying our population will level out at some arbitrary capacity and at worst it just gets ignored. You're not going to convince me here and neither I to you. I've spent years in university studying this as well as on my own time. I'm sure you've put a similar level of thought into this. I'm not saying we are certainly doomed, we can only try our absolute best because the stakes are too high.
One way to help the oceans, is to eat less fish
I always feel like we fish way too much. Like I wonder what percentage of fish at the supermarket gets tossed out. Cuz outside canned tuna and other uses for fish like pet food and such, I don't know many Americans at least that eat fish on a regular basis
Eh? I lived in Worcester, MA for years and fish was a regular menu in just about every household I was acquainted with. It's also available 5 days a week at the school cafeteria. There were three seafood restaurants within walking distance of my apartment, plus a posh one right next to the school. Worcester is an hour's drive from the sea. I can only imagine the amount of seafood Bostonians consume.
As a Bostonian, I'd eat seafood multiple times a week if I weren't also a vegetarian.
"I don't know many americans at least that eat fish on a regular basis."
And there's your problem. The US is probably one of the worst countries to based your information upon because americans in general tend to have really lousy diets and aren't as big on fish as they are on meat, especially pork and red meat.
Here in my household we eat fish about 2 times a week. Salmon, tuna, cod, european hake, european seabass, horse mackerel, squid, common sole, grouper and red snapper are the most common fishes we eat (other households may have more or less variety). We live in western europe and our diet is mostly mediterranean. My country is one of the world's biggest consumers of cod (imported from Norway), it's like a national staple here.
@@fruitymonkey8641 Makes sense. Countries/states by the sea may eat more fish than those who are landlocked.
Very disappointing to see SciShow talk about blockchain technology like this. Crypto evangelists love to talk about how blockchains are unhackable but ignore the fact that almost all fraud happens because an authorised user deliberately inputs false information into the system, i.e. a fishing boat lying about their catch. This is a problem that blockchains not only don't solve but also can't fix once it's been discovered, since the false data is immutably recorded on the ledger. Other than that, a great video.
Not to mention their brief mention of it being "energy intensive" is uh bit of an understatement.
Immutability isn't necessarily a problem, you just add a type of log entry that represents a correction to a previous entry. The original entry remains untouched, and then you not only fix your data, but preserve a record of the original error and when it was corrected, which could be useful for accountability purposes. That being said, there's plenty of ways to do immutable ledgers that don't boil the planet (if you've ever used git that's a perfect example), so this is in no way a defense of blockchain technology.
We could also just ban the nets that are causing all the problems and switch over to lines since you can target the fish by using different baits and sizes of the hooks. He also forgot to mention how those giant fishing nets destroy deep sea coral ecosystems.
Going from catching hundreds or thousands of fish from one net is far more efficient than using lines and hooks, unless there's something I'm missing. Feel free to fill me in.
"Just ban"
"30% of fishing is illegal"
Problemo visibilo?
@@DasAntiNaziBroetchen It's a lot easier (though not necessarily easy) to detect and punish the use of nets compared to the sale of mislabeled fish. False equivalence doesn't help anything.
@@JohnDoe-xp4iy thats the point. We are overfishing our oceans and decimating the coral reefs they live in. If we catch less fish they have a better chance to repopulate.
@@DasAntiNaziBroetchen I agree. Fishing practices how they are now are super fishy. But putting a ban where 70% of the companies listen to it is already a huge win. Like the video said we do need to find a better way of regulating fishing since that is a big problem.
Sovereign indigenous people using their knowledge and language with science need to protect all ecologies on Earth. If you ever watch these things get that feeling that something's missing from your equation on how this needs to be deployed. It's that.
I gotta say, I love these videos and this channel. I love learning more about the world that I occupy and appreciate the way you give me information.
more efficiency means they will take out even more of target species, even if bycatch is reduced.
Chris, from 2:20 he starts to explain about over-fishing and how this can be mitigated. First, we need a better way of collecting data on fish numbers so quotas can be established to keep the population sustainable. Second, we need cameras on boats to keep them honest. AI technology can be used for both purposes for both data collection and recording all fish brought on board using the cameras.
The hardest part is getting the fisheries to agree to the cameras. They are highly resistant to allowing that every where a government tries to improve the industry.
5:03 Had you not mentioned this, I was about to comment it. Well done.
BRB gonna figure out how to program a school of fish to run doom
Every Nation must work together to achieve real progress in the oceans. Scary🤯
Wow those are some wild ideas
This is really cool
SciShow should do a video on Advanced Fish Farming, Fish Nutrition Research and New Research on fish phenotypes. Would love to hear some info on those topics.
Good luck having everyone play by the rule. The fish black market is too big.
Fish black market? *China has entered the chat*
I was a bit underwhelmed with the innovations on this if im honest. Doesnt seem like anything is really going to change much. Sucks to be fishermen but i think zoning of critical areas and restrictions on catces is the way forward on this
Thank you for this episode. The status of the ocean causes me personally a lot of stress. Not often do I hear good news for our oceans, but this gives me hope.
No pun intended, please do a video about String-net Liquids.
This is good info especially after that documentary on Netflix that talk about us over fishing
Damn, even fish are getting into the NFT game.
I actually think that if we could implement something like that tracking where things start out and where they end up with a low energy block chain like system that the real world implications of that would add extreme monetary value. I do also think that there would be quite a fight to resist it form countries, organizations and peoples whom would rather their lives be less well known to others.
First of all you would need to slowly set the idea into motion starting with the most valuable and important items down to the least important and valuable items though one might imagine that a scenario like that where the power issues have been negated and the divisions are continued onward might end in the whole planet being divided up. It would enable more circular thinking and creating systems that don't end with so many items being thrown in the trash let alone ones that go unused.
I can see rich people being like "This lobster/fish/whatever is from XY. Look at the block chain entry. 😏" or expensive restaurants advertising their blockchain verified fish.
Seed the oceans with iron. Doing this to the max can pull a sixth of our current emissions out of the atmosphere and turn it in to fish food.
good thing iron's free and also good thing that massively altering the ocean's chemistry won't have any unintended consequences

The word “sustainable” has become so green washed, corporatized. True ethical choices are almost made entirely individually on a small scale. The ocean is so vast- accountability is an almost impossible feat. But if we have any leverage against profit driven companies into playing nice, we should use it to prevent tragedy of the commons. I hear most pollution in the ocean is fishing related. Maybe we have some duty to clean up while we’re scooping fish into dry land 🌟 🎣
You are right, nost of the plastic in the ocean is from discarded fishing nets
Ironic that we focus our attention on plastic straws and the like, which make up a tiny % of plastic in the ocean, when simply not eating fish would have a much bigger effect!
It's a dirty word that people really should think twice about when they see used by a company/person.
@@Jack-tk3ub No, we still need to eat fish. If you don't eat it, the population would get out of control and destroy ecosystems. Doesn't matter if you like it or not, we ARE apart of that ecosystem and need to help keep it in balance. The solution is not over fishing.
@@BeckyNosferatuThe ecosystems in the ocean have been around for millions of years before humans started fishing. They would be much better without us
@@BeckyNosferatu That is a wild way to rationalize exploiting the environment my dude. Ecosystems always do best when we leave them the f alone. Your comment sounds like fishing industry propaganda tbh
tuna are way way more expensive than like all other fish. I seriously doubt we're gonna put QR codes on cod and herring

@@ranimeRAT grows them
Two critiques from a citizen of Catawba Nation which has been sustainably fishing our River for millennia. 1. “Over the last X years we have gotten a little too good at catching fish” I know this is was a rhetorical argument but still, the very fact that this video was made means that “we” have gotten significantly worse at fishing. 2. At most these solutions can only address half the problem. Sustainable fishing requires (at least) another aspect which is protecting and growing the landscape. Love what you all do, but when considering the question of “sustainable XYZ” maybe first turn towards Traditional Ecological Knowledge and consider how indigenous/land-based communities have solved this problem over thousands of years. Hawu!
Question: How do scientists know that fish mass has been reduced to 60% since 1800, If only 5% of the ocean has been explored?
Because it's harder and harder to catch these fish. The open ocean is a lot like outer space. It's a lot of nothing for miles and miles.
Because it's not 5% anymore now it's around 20% and the other 80% only has microscopic organisms and giants have you ever played Subnautica? Do you know how the edge of the crater says only microscopic and leviathan class can live there? Yeah that's 100% accurate.
How to sustainably fish: you can’t. Lol

look as much as block chains promised de-centralization, it absolutely doesn't do that, at the end of the day there needs to be an organization or group of organizations managing the trasactions. i mean just look at crypto, majority of people don't actually have personal crypto wallet but instead have one hosted on a few select slightly sketchy websites. a block chain ledger would be no more effective than a normal database ledger. so of course i'm going to roll my damn eyes at it.
I really hope fishing becomes more substanable
I very rarely eat any seafood.
I really hope countrys crack down on by catch. My buddy is halibut fisher they use long fishing line, but they know that the trawlers can catch 10s of thousand of pounds of halibut in one day most if it being by catch that dies and just gets thrown over board its a serious problem
China: we don’t do that here
I've read somewhere that a lot of fishing goes to feeding the super-rich. I want to find more statistics about who is actually buying all these fish, especially the illegally processed ones.
Asian cultures
Most commercial fishing (especially the more destructive net-dragging kind) actually feed the food processing industry. The vast majority of commercial fish go to canning plants. It is therefore not true that commercial fishing primarily feed the super-rich - quite the opposite. It is, however, true that feeding the super-rich is the primary cause some types of fish are now endangered. This primarily applies to tuna, but there are also exotic fish (especially in the Asian market) that wouldn't get eaten if not for the novelty value.
A lot of fishing goes to feed farmed animals. Fish meal and by-products are a common ingredient in animal feed.
I don't think Blockchains are inherently energy intensive. After all, they are simply a chain of blocks where the las block contains a cryptographic hash of the previous one, recursively. So, as long as the Blockchain ()or even just the hashes) is published openly, it's impossible to manipulate.
The energy intensive part is part of the decentralized system, which isn't really an issue in the case, because the UN or whoever would easily host this Blockchain, which could be mirrored by anyone else, with guaranteed data integrity
You are technically correct, but that's not what anyone thinks when they hear the word "blockchain", that word's been poisoned by the cryptocurrency community. IMO a science show like this referring to "blockchain" is irresponsible, since it gives legitimacy to the inevitable wave of Etherium guys claiming they have a solution. It's a good term, but i think for the next few decades we'll have to call it like a "hash-based immutable log" or something to avoid getting overrun by crypto bros.

We have to stop encouraging people to become fishermen/give people less of an incentive to be one. We should give more access/opportunities for people to become fishery entrepreneurs instead, with sustainable practices.
I've seen too many videos about how we are overfishing in the ocean as well as the side effects of having fisheries where they pollute the hell out of the area they occupy. This should be one of the priorities of the government.

Anyone can make NFTs that point at anything and by their very nature, being based on decentralized smart contracts, there is no authoritative body that determines who is actually legally allowed to do so.
Everyone play by the rules.. right. 😀
Why not just ban fishing for a few years? I mean its a drastic measure but atleast it ill give them some time to repopulate again. Or would this not be a decent solution if not temporary?
Too many people are dependent on seafood. But I see where you’re coming from
It would almost certainly never work: too many countries (and by extension people) rely heavily on fishing for food and economic activity, and are thus unlikely to agree to it.
It also took us decades of commercial fishing to get to this point; a few years of ceased activity are unlikely to fix that damage done in any substantial way
That's like saying "Why not stop fossil fuel for a few years?" no country in the world can see far enough into the future to realize the benefits.
But if we stop bycatching, does the ocean will rise faster? ;)
No
Play by the rules. Well that's where your first problem is the second is sustainable consumerism.
We really need a large stick wrapped in a small amount of foam so that it's not lethal. We can then use that to smack anyone who refers to brokechain as if it were meaningful in any way towards solving a problem. (Using "brokechain" instead of the term that brokechain cultists prefer because 1. it's a solution looking for a problem rather than actually useful technology, and 2. bots key off that word.)
What brokechain does that they are wanting here is a procedurally generated non-sequential identifier and a database. Your fish is only going to be tagged with an ID, effectively just a large number, which would be generated by some procedure that ensures it's neither repeating nor sequential. Not being sequential is so that people can't just tag their fish with a number they expect the system to generate in the future.
Brokechain does this by working out difficult math problems and assigning the resulting large number to a fish. Unfortunately for this plan, there is nothing stopping an illegal fishery from reading a blockchain's data and randomly assigning existing ID to their fish, which is why decentralization is NOT what you want in an accountability database. An accountability database needs the data to be accessible only via comparison. In a database this is typically done by hashing a value, encrypting it in a way that is not reversible. Then you apply the same hash to the value you want to check and make sure the result matches what you stored.
The only current way to break a hash is to have access to the hashing algorithm and generate a large number of comparison samples, which is infeasible for large values. This is why they aren't considered to be particularly vulnerable to quantum computing, nor to most realistic attacks. But critically, the other half of breaking a hash is that you actually have to have the stored hash. When you hear of a breach where people's data is stolen from a hashed database, that usually involves a very large database (called Rainbow Tables) of pre-hashed common text values to compare against the stolen hash. The longer the text strings, the more difficult this becomes (which is why you should be using 16+ characters, not 8).
Brokechain would record the value in a hash as well, but it's giving the hash and the hashing algorithm to everyone. That means nobody has to breach any system to start working against the hash. And importantly, they don't need a specific value out of the chain, they only need to break ANY number. With roughly 1 trillion individual fish being caught annually, they only need to guess and confirm via hash checking a few thousand per operation per year. While your fish brokechain is churning feverishly to calculate a specific value, they can spam numbers in the expected range far faster with far cheaper equipment until they stumble upon one that matches an existing hashed value.
And because you're relying on brokechain to ensure uniqueness, you have to do this as part of your node generation. For each of the 1 trillion fish. If you don't rely on it for uniqueness, people can generate their own illegal fish IDs in the system using a stolen hash value from a random fishing regulatory body and you'd just have to rely on "trust me, bro" to tell if their registry is real or not within the system. That means even with the smaller impact brokechain designs being used now, the processing power required is going to be insane for something that can be broken by brute force.
We have plenty of centralized systems that do this job FAR better in regulating things like banking transactions on global markets. Those operating illegally don't have access to the hashes outside of breaches, and when a breach occurs, the relevant data can be changed and rehashed to prevent ongoing exploitation.
And that's without getting into future proofing. Right now, brokechain is scrambling to adopt "post-quantum cryptography" options out of fear that growing available of quantum computers will leave them vulnerable. This isn't the first time cryptographic technology has had to scramble because smart people with improved technology found a way around it, and it won't be the last. Being public and decentralized sounds good in the democratizing feel of those words, but in practice it means that you can't hide things away while you're trying to fix them and you can't replace them without everyone seeing what you did and having an inroad into breaking your newest protection. You can make things secure with open technology, and open source does some wonderful things with this. But storing your DATA openly is not the same.
I described brokechain as a "solution looking for a problem" because fundamentally it does a thing that you don't actually want done when you actually think about it. It doesn't democratize things by decentralizing data processing and authority, it just mislabels "I did a thing with my expensive computer" as "authority". It doesn't protect data because the encryption is more vulnerable than proprietary data. And it doesn't ensure agreement over a transaction history, it merely mislabels "first" as if it means "true". All of the things it purports to do are no more true than a politician using stock phrases like "family values". Those of us who actually work in IT have been warning you for years that it's digital snake oil.
The insane loopholes society must go through to make unsustainable practices remotely sustainable is absurd when the most obvious and easy solution is to simply stop eating fish.

Not going to happen. Instead less fishing let them build up.

proof of stake in what? make an entire currency just to serve as a basis for a fish database? even if this made sense and were implemented, one or two rich countries invests in the majority of the tokens or whatever, and then we're back to more or less a centralized database, but way less efficient.
What you could do is set up a treaty where each member country gets to run a node in a global database, that maintains distributed consensus through a voting protocol, preventing any one or few nations from cheating without being caught. And you could even maintain an immutable log by including the hash of the previous entry in each entry, preventing anyone from retroactively modifying a record without it being immediately obvious to all other parties. But cryptobros would immediately disavow it because even though that looks and sounds a lot like a blockchain, it uses a bit of bureaucracy to regulate who controls the nodes instead of burning tons of coal and/or ever sketchier financial instruments to hack together a free market solution.
realistically, governments being governments, it would be a hodge podge of crappy websites with big tables of numbers and CSV files, with agents periodically doing painful excel stuff to audit other countries' data against their own. which would still be orders of magnitude more efficient than blockchain and just as effective
@@spambot7110 Unfortunately we live in a very capitalistic world and so yes I think an incentive is needed, for normal people to keep the blockchain. Also there is delegated proof of stake where you would lose your power as soon as you act against the community.
Plus we live in the real world where if you hacked the fish blockchain there would be extreme consequences
@@bobthegoat7090 why would you want "normal people" to run nodes? I'm talking about governments running essentially a private, permissioned blockchain amongst themselves. governments don't have to act on a profit incentive, they can act on the public good (regular people are capable of this too btw! think of folding@home, BitTorrent, and Tor, or more broadly, people volunteering, giving donations, helping out neighbors, etc).
Odd, I saw studies recently that said that most of the biomass in the ocean is in lanternfish and other midwater fish. So when you say 60%....
Yes, that's the point. The situation is now this way BECAUSE we've lost so much of the other species.

Could this be remedied if everyone became vegetarian or vegan?
This is the obvious and most simple solution.
We can’t even get everyone to take a life and community saving vaccine. How are we to force everyone to become vegan or vegetarian?
@@Ladypuppy510 nobody can force anyone to do anything, just like getting vaccinated, veganism is a logical solution to many problems; doesn't mean anyone will care
@@Ladypuppy510 well if they did the 2.5 years of testing that is normally required before a vaccine is permitted to be distributed then maybe more people would take it. The only person in my household that has been vaccinated suffered the worst when we caught covid, so from my veiw point so far it is actually worse to be vaccinated.
@@justinweatherford8129 that vaccine actually had over 25 years of testing behind it. It’s a SARS virus. They’ve worked on vaccines for it for years.
we as in corporations?! there where lots of sustanable fishing methods since the dawn of history. overfishing is a deliberate feature of capitalism. its not about supply or demand, but the blind dumping of fish in land fills to control prices instead of sharing it around or feeding the poor. more fish are thrown away than consumed, you cant just ignore the real facts on the ground to sell new tech
Glad I hate the smell of fish and never ate one in my life.
That 30% for illegally caught fish is probably WAY higher.
FISHY NFT s 😁
I can see the target fish adapting to the lights, resulting in inefficient hauls
How much is 50 clams in Bitcoin?
"Health of our oceans" yeah just go vegan
I've been saying for years that blockchain technology is great for supply chain control like this mentioned, nice to see it said elsewhere
