Term	Definition
B_20%	WILD CAPTURE B_20% B-virg. Level of spawning stock corresponding to a fraction (here 20%) of the unexploited biomass. Virgin biomass is estimated as the point where the replacement line for F=0 intersects the stock-recruitment relationship or as the biomass from a spawning stock per recruit curve when F=0 and average recruitment is assumed.
B_lim	WILD CAPTURE Limit reference point for spawning stock biomass (SSB). Below this value recruitment is expected to be ‘impaired’ or the stock dynamics are unknown. Below B_lim there is a higher risk that the stock could “collapse”. The meaning of “collapse” is that the stock has reached a level where it suffers from severely reduced productivity.
B_lrp	WILD CAPTURE a lower limit reference point for spawning stock biomass (SSB), for which Blim and B20% are commonly regarded as proxies.
B_MSY	WILD CAPTURE Biomass at MSY. Biomass corresponding to Maximum Sustainable Yield from a production model or from an age-based analysis using a stock recruitment model. Often used as a biological reference point in fisheries management, it is the calculated long-term average biomass value expected if fishing at F_MSY.
B_pa	WILD CAPTURE precautionary reference point for spawning stock biomass (SSB). It is precautionary buffer to avoid that true SSB is at B_lim when the perceived SSB is at B_pa. In general, management advice is aimed at avoiding the risk that the spawning stock falls below B_pa. However, B_pa should not be regarded as a target reference point (B_trp).
B_trp	WILD CAPTURE an upper target reference point for spawning stock biomass (SSB), for which B_MSY and B_40% are commonly regarded as proxies.
