MACKEREL FISHERMEN FIGHT42% TAC CUT

摘要

ICES has advised a cut of 42%, from 550,948 tonnes in 2018 to just 318,403 tonnes for 2019, claiming its advice is based on poor recruitment in recent years, but fishermen say the stocks are huge. According to ICES, the spawning-stock biomass (SSB) increased up to 2011 but has been declining since then. The stock is estimated to be below MSY in 2018 - the first time since 2007.Fishing mortality increased after 2012 and is above MSY. There was a succession of large year classes after the early 2000s but the 2015 and 2016 year classes are estimated to be below average.
