Daily Egg Production Estimates for the Atlantic Iberian Sardine in 2020, (ICES areas 9a and 8c).
The spawning stock biomass (SSB) of the Atlantic Iberian sardine (stock pil.27.8c9a, ICES divisions 8c and 9a) has been estimated using the Daily Egg Production Method (DEPM) since the late 90s. The surveys and analyses are internationally coordinated in the framework of ICES-WGACEGG where IEO (Inst...
