This video has taken 4 months to appear on my feed, despite being on alerts. Well done, Rodrigo. Thanks for bringing the scale of foreign fish invasion to our attention.
The quality of the speaker and video material is world-class. This channel is extremely underrated. I hope the subscribers and views soon match the quality. That’s why I’ve subscribed!😝
Thanks for posting! We also have a huge problem in Southern Africa, as introduced basses, trout and carp are basically taking over and wiping out indigenous fish species. The biggest obstacle we have in remedying the problem is the recreational sport fishing fraternity who by and large don't really care so long as they can catch and release their favourite alien exotic invader species.
BTW the best way to remove bass is during the spawning season, when you can catch the big ones and breeders easily by dragging a lure such as a spinnerbait through their nests. Carp are best removed by netting them when they gather near river inlets to spawn in early Spring.
@@majorbruster5916 Thank you! I used to be a strict catch and release angler in line with the Bassmaster ethos until I discovered just how destructive exotic alien fishes are to the ecosystems in which they were introduced. One of my "hopes" is that more recreational anglers would help in removing them so as to give the natives a fighting chance at survival. Carp are especially damaging to biodiversity and tend to take over completely after a while, and if every one of the millions of anglers removed just a few every season it would go a long way towards remedying the situation. Granted it is very difficult to take out all of the aliens once they are established, and certain enclosed waters could remain designated bass or carp waters where sport anglers could do their thing - but everywhere else they don't belong, they need to be removed. A few solutions include electro barriers in streams and rivers that still hold reasonable numbers of native fishes to prevent the expansion of aliens. A small river or stream could be diverted in stages and selectively netted out prior to the installation of the barriers. Commercial netting licences can be granted to fishermen who would net out the bad guys and release any natives. This works well in Utah for example, where the carp are sold to ensure that costs are covered. In Africa, the less privileged would really appreciate a source of good protein - carp are actually great eating when prepared correctly. Have a good one and thanks again for your support.
I live on the other side of the Iberian Península, similar latitude, just next to the Mediterranean. I live right next to a small river, most of you would call this a small stream due to the little amount of water it carries year around, which is now continuously drained for irrigation but then refilled by waste water treatment plants. The river is home to a species of fish (Squalius valentinus) that only lives in a handful of rivers in the region. The regional government does not even includes it in the list of protected species, meanwhile it confronts dessication, competition with invasive species, pollution and habitat destruction on a massive scale. Iberian rivers are a silent dissaster. Thank you Rodrigo for making this tiny documentary.
@@Chickennuggetjoes for some people once is not enough, they born that way. Frontal lobe is not fully developed and they stuck in this half mature/half retarted phase
Glad someone is paying attention to the problems, in the UK our waterways are getting worse and all people care about is Beavers and otters, we need to look after everything. I particularly am interested in fish.
Caro Rodrigo, Muitos parabéns pelo seu trabalho, que se reveste de uma importância extrema. O ruivaco do oeste , descoberto há pouco mais de 15 anos esteve mesmo à beira da extinção e ainda se continuam a descobrir espécies novas, mesmo à beira da extinção, como a boga de Lisboa. Continuação de bons trabalhos.
Very interesting, and sad as well, video about the rivers of Portugal and describing the problems with the unwanted release of aquarium fish in the local rivers. Excellent narration 😊👌
Mais um excelente vídeo e com uma qualidade fabulosa. Parabéns!! Continua o excelente trabalho. Uma sugestão agora: peixes da costa. Peixes que podemos encontrar numa visita a uma praia. Agora do Norte. Mas não peixes de água salobra. Bom trabalho!!!!!!!!!!
Muy buen trabajo Rodrigo, una verdadera pena 😢 ver como algunos de nuestros ríos y sus especies endémicas se encuentran alterados con especies introducidas. Un saludo y gracias por el excelente material gráfico
I live in Quinta do Conde in Portugal and am an author, a naturalist and environmental activist. I found this video very interesting, though also very sad to hear of the declines of so many endemic species and to hear of the threats they face.
Fantástico, este documentário só peca por tardio e curto, deveria haver mais esforços por manter estas espécies vivas porque é muito triste perdê-las, mas sabemos que é quase impossível mesmo que houvesse milhões disponíveis para tal. Vivo em Trás-os-Montes, aqui há (em declínio abrupto) todas as espécies relatadas no vídeo, mas os rios estão invadidos pelas espécies invasoras relatadas. Neste verão visitei o Lago de Sanábria e lá parece que ainda é um santuário, pois havia grande quantidade de Bogas Portuguesas, Bogas comuns, Escalos do Sul, Barbos… É interessante mergulhar naquelas águas cristalinas, pois temos o prazer de ser acompanhados e rodeados de muito perto por estes peixes. Foi-me relatado que já há Lúcios nesse lago, nos mergulhos que dei não vi sinal deles, mas era de admirar não haver, é uma questão de tempo. O filme foi muito bem realizado, a narradora esteve top, principalmente quando pronunciava os nomes em português.
Hi there, the fishes you have shown in Spain are there in Srilanka lakes. If you really want to see beautiful wild fishes you must be visited Srilanka 🇱🇰 . Btw love your videos them can calm down the mind ❤️🙏
Me and made me glad I don't live in Europe but at least you'll get to experience some of my fish LOL no different than I get to experience fish from other countries that are invasive here
@@majorbruster5916 They refer to a literature record from 1927, but that was long before holbrooki got species status. Back then, both affinis and holbrooki were lumped together as a single species. Note that the Italian populations are derived from the Spanish ones and also note that Vidal argues that all populations in Europe should be referred to as holbrooki unless new evidence is provided. - It would be extremely interesting if someone checks the Hungarian population because it is very isolated, non-Mediterranean and might have a different origin from the others ...
i am sorry, but i find this video quite misleading and actual spreading disinformation, statements such as widespread and in every river basin are used carelessly throughout the video, if you look on reports and and actual areas where some of the invasives are found, they are limited to the south, unless the authors consider Portugal as only Lisbon and the south, i would rather they corrected the video to ensure it is accurate, unless they just want to scaremonger and maybe find funds.
We did look at the reports. The only invasive restricted to the south is the chameleon cichlid, as we mentioned. Yes invasives are in almost every river basin. There was no financial incentive, the video was produced at a loss. Spreading negativity on a video that was completely free for you to watch and is actually raising awareness.
@risilva its not negativity. Can you find lepomis in Douro? Or in Lima or Minho? The video is great quality, but generalising does not help. Even in Nabao, i always look for fish in there never found any of these species. Not saying it is not an important problem, but if trying to make a video as scientific we should tey to be accurate. Meant as positive criticism, not negative
Yes you can find lepomis in the Douro basin. You can actually find it in every river basin in Portugal. We actually do our research and use reliable sources, rather than anecdotal reports such as yours.
@@risilva i stand corrected then, apologies. i will delete the main comment so people dont get misguided by the comment, i have been looking for reports of introduced species in Portugal and could not find them. thank you for the videos by the way, very well produced!
Hi mate, Croatia has 137 freshwater fish species and 49 of them are endemic...we also have big problem with invasive species. Please contact me if you are interested into filming freswater fish in Croatia, I'm ichthyologist in Croatia and I will be glad to help you !

Amazing documentary bro!!
It was a pleasure to help you find some of these native and invasive species!
Thanks again!
Worm and a hook will catch all those pumpkinseed and Bass 😅
Think twice before releasing your unwanted aquarium fish into wild life...
Think once and realize you shouldn’t do it.
@@Chickennuggetjoes for some people once is not enough, they born that way. Frontal lobe is not fully developed and they stuck in this half mature/half retarted phase
It’s not that serious.
@@USMC978yes it is.
@frowner_and_co look at all the invasive plants and animals everywhere. There’s still people thriving there.

Pls make more documentaries. I personally find it very interesting and even relaxing.

very informative and well presented - a video to be proud of
I’m surprised bluegill aren’t invasive but pumpkin seeds are instead they aren’t as widely available as bluegill
Thank you for providing manual subtitles. As a deaf person I am very grateful.
Muito fixe! PARABÉNS!
Vivo em Queijas (Oeiras) e gostei muito de ver este pequeno documentário. Excelente trabalho.
Muito obrigado!
Incredible video
Thanks for making them
Thanks for a very informative and interesting video
Excellente super documentaire grande Rodrigo sempre em acao um abraco
Thank you 🙌
Excelente iniciativa! Parabéns!
I think this is the best channel I have ever found the footage is amazing love it plus the voice goes so perfect with the video is so calming
This content is amazing!!
Que alegría saber que la fauna Portuguesa no está olvidada y que se encuentra en buenas manos! 10:05 🐟

How do you not have more subscribers?
Thank you! 🙌
Ur awesome brother! Film the Mediterranean grass beds. Hippocampus galore with pipe fish etc...❤
Agora sou eu quem deve agradecer. que relaxante.
The damage caused by introduced species is almost insignificant compared to the damage caused by fertiliser runoff and hydroelectric dams etc...

Very nice 👍👍👍
Nice video👍👍
Thank you 👌
The funny fact is that they say that acclimatized fish to North America is threatening to local fish 😂
Changing, NOT destroying... They are still rivers and there is still fish in them, maybe even more than before, just new ones
El cangrejo americano es fundamental en la dieta de los barbos andaluces
saudades das minhas verdemas.
Please reply sir....can i use your betta fish vedio and dub it into bangla please
Yup, sunnies. Theyre a fish.
The spinde louch is not in danger in nl we have them to
You have southern Iberian spined loaches in NL?
Me and made me glad I don't live in Europe but at least you'll get to experience some of my fish LOL no different than I get to experience fish from other countries that are invasive here
Should be Gambusia holbrooki, not Gambusia affinis. I don't believe there is any G. affinis established in the wild anywhere in Europe.
Although Vidal et al 2010 state that G. affinis was introduced into Italy and might still be present.

Is this his official page? Cause there’s a bunch of people reposting his content
Yes this is the original, where has it been reposted?
Tuche'. We have a bunch of invasive european fish in US waters
in the title why Europe if its just portugal and maybe spain? europe is bigger then just he 2 countries
