| Summary: | The ICES Working Group on Mackerel and Horse Mackerel Egg Surveys (WGMEGS) met in Reykjavik from 7–11 April 2014, chaired by Cindy van Damme (IMARES, the Netherlands) and Finlay Burns (MSS, Aberdeen, Scotland), to evaluate the results of the Mackerel and Horse Mackerel Egg Survey in 2013 and to plan the North Sea Mackerel Egg Survey in 2014. Its main objective is to relate the number of freshly spawned eggs found in the water column to the number of females having spawned these eggs. With the estimated fecundity of the females, this provides an estimate of the spawning-stock biomass. In 2013 the Faroe Islands, Iceland Portugal, Spain, Scotland, Ireland, the Netherlands, Norway and Germany participated in the survey. Despite technical and weather problems, temporal and spatial coverage was sufficient in order to deliver a reliable estimate of mackerel and horse mackerel annual egg production. The application of an alternating transect survey design enabled survey effort to be deployed over the wide spatial ... |
