The fisheries affected are:
Fish stocks (or Spawning Stock Biomass) measures the mass of the adults in a population of fish. It does not count juvenile fish. Recruitment is the process of juvenile fish maturing into adults and joining the adult population – where they can also breed. Poor recruitment years can be caused by a variety of factors including fewer eggs or a smaller proportion of juvenile fish reaching maturity – e.g. through food scarcity, disease or predation.
ICES defines MSY Btrigger as “Value of spawning stock biomass (SSB) that triggers a specific management action”. To explain: Maximum Sustainable Yield (MSY) – or sustainable – stock level tends to be a band, rather than a single point and MSY Btrigger is the lower boundary of the band. It is often regarded as a precautionary limit. ICES uses MSY Btrigger as a point where falling stock levels should trigger rebuilding response by fishery managers. Usually this would be a strong reduction in catch or suspending fishing entirely to allow for stock recovery. For media queries, please contact your nearest MSC representative
