Why is it important to know about maximum sustainable yield (MSY)?
To manage human take from the wild, one needs to know how much can be safely taken without
depleting the resource one wants to take from, and without otherwise negatively impacting the
environment. Fishing is no exception. As scientists and managers have discussed how much fish can be
safely taken out of the sea one concept has become a key tool for fisheries management: maximum
sustainable yield (MSY). In order to participate in the debate about fishing limits, one needs to have an
understanding of the basics of the MSY concept. This briefing is aiming to provide this.
