We've talked about how to design better feedback systems for change, rather than simple legislation of specific practices or minimum standards. These ideas have been applied to things like air pollution and energy, but they have yet to make it into fisheries.
Tidepool.org writes about how the current methods of regulating fishing catches to protect endangered species are a perfect candidate for better feedback loops, and has the beginnings of some suggestions for "ocean cycle-based management". The problem, as they describe it, is this:
Our current regulatory system is slow to react to changes in our ocean, and the lag times this produces tend to hurt everyone... This lag biases against the fish when they most need protection, at the early stages of a decline, when overfishing can produce major damage that could take many years to undo. And the lag also biases against the fishing communities when the fish least need our help and when the fishermen need it the most.
