    The issue we have in the UKCS is not declining populations of fish, its exactly the opposite. We have too much fish and not enough feed in the sea to support it.
    You only have to do a scale test on a Haddock to find that Haddock in the North Sea are seriously underweight. A four year old Haddock in Iceland weighs between 1.5 and 2 kilos. A four year old North Sea Haddock weigh between 400 and 500 grams.
    The decommissioning of hundreds of UK and European Fishing vessels, along with drastic quota cuts in the last 20 years has led to fish populations spiraling out of control.
    The base chain of feed in the North Sea starts with Phytoplankton, a microscopic Plankton that depends on Sunlight, much in the same way as the leaves on trees depend on sunlight. They are the food that bigger Plankton depend on which small fish then feed on and then bigger fish feed on them etc etc. When you have too many of one species in the chain, which is the case with Haddock, the whole chain breaks down. All your doing with creating MPA's and stopping fishermen from fishing is accelerating the destruction of fish stocks in the North Sea.
    Fishermen ARE the custodians of the sea, you guys need realize this.
    Fish are starving, eventually they will be come infertile and stop spawning. Then you will have a real problem on your hands.
    And by the way, unlike the so called scientific advisers you claim to have, I worked in fisheries and marine science for almost 40 years. I actually do know what I'm talking about.

    Great video that is both visually appealing and scientifically interesting - a rare combination, thank you! It is clear the ecological benefits of land-based parks, such a shame that we are not as supportive of ocean-based parks at the same level.

    These are just great BUT, it would be nice to know--exactly where the boundaries are. So, you are in your boat, and here in California, the DFG HAS THE NERVE TO SAY "you have probably been in one---and didn't even know it" Ha HA, not so funny when they arrest you. Look on line to find out how to know where the boarders are--we need software for our chart plotters and go apps for our phones , that are easy to install
