Well if those who are estimating what we take are using figures from an angling org, then yes watch out just like bass has been restricted the proof is there for all to see.Watch out for angling being restricted for cod next.
And there lies the problem!There was enough for man`s need but there will never be enough for man`s greed ...Alan
So my thinking is that the large beam dragged say 1,000 metres is 100,000 square meters totally obliterated. But the smaller trawlers would be cris-crossing the areas that other trawlers have left destroyed and leaving areas untouched so there would be islands of life able to re-colonise the areas from within rather than having to do it from the edges.Why will 10x10 m beams do less damage than one 100m beam?
Can't see it myself 100m of beam is just that whether it's big or smaller boats. these larger nets are better constructed to allow undersize fish to escape and they have cameras to show what is going on with panels that open to release shoals of unwanted species (apparently}. They really don't want to waste time catching and dealing with the wrong fish. One large boat definitely is more environmentally friendly , fuelwise, than many small boats. End of the day , the quotas need reducingively, breeding and nursery areas need to be set aside as do general areas on a rota system. I may sound as if I am defending these trawlers but they are just a sympyom, not the problemSo my thinking is that the large beam dragged say 1,000 metres is 100,000 square meters totally obliterated.

In practice I guess they could still wipe out the sea bed faster than it can recover but a bigger beam can do it sooner with more certainty. Plus I guess there's only two sides the fish can escape from as it approaches as opposed to the twenty you'd have with the smaller trawls which will add to the devastation.
