from what i have been told by family who work in the fishing industry, catching only the fish over a certain size is often a missguided and damaging policy not founded im science. Mature fish can reproduce regularly with the expectation that the vast majority of their young will not survive to sexual maturity, by taking only those fish you are removing the source of new fish. Better to throw back the big ones.

- qchris 5y agoThis is one of the big reasons why marine protected areas (MPAs) are such an important strategy for both fisheries and conservation. When areas totally free from fishing pressure are created, the fully mature individuals within them are much more reproductively successful. This can fairly quickly lead to spill-over into the unprotected adjacent areas, which in turn can become a more productive fishery than if the entire area was open to begin with.
