Managing fish size and abundance
As well as deciding how much fish to give to different sectors, we also have to decide how large and abundant we want the fish to be.
Managing fisheries at the level of Maximum Sustainable Yield (MSY) lets commercial fishers catch the greatest amount of fish, year after year in a way that is sustainable.
However, recreational fishers often want to be able to catch big fish more easily. This may mean reducing catches to below the MSY level, so that more fish can grow larger.
So managing a fishery to best suit both recreational and commercial fishers is not always possible.
