Same for all species Ray Big fish grow from Small fish. :wink: My point was really in answer to the question of which would be most beneficial to return. One big fish or 1 little fish. With the evidence that the bigger a fish is the more it can contribute to the future generations (ie One 20 pounder can outspawn many 6 pounders), then my answer would be its better to return a single bigger fish than a single smaller one. But I wouldn't feel unhappy about anyone taking a fish of any size or indeed returning it, so long as they didn't expect everyone else to do the same.
