biomass at MSY
the long-term average biomass value expected if fishing at FMSY (the fishing mortality rate which, if applied constantly, would result in maximum sustainable yield. Can be estimated from simple biomass-aggregated production models or from age-structured models that include a stock-recruitment relationship). Abbreviated as BMSY
