Maximum Sustainable Yield

Description

A maximum level of yield that can be continuously taken from an exploited stock under average environmental conditions. It can be defined given biological parameters (e.g., natural mortality and stock productivity) or using proxies (e.g., the maximum yield at 40% of unfished biomass). Units depend on units of catches.

Rationale

Many management frameworks are based on calculations of MSY despite difficulty in its estimation. Metrics such as fishing rate at MSY should be abbreviated using all upper case letters but this is not common practice as of yet. For example, sometimes you will see F_msy or some derivative thereof.

Alternatives

msy, MSYproxy
