Towards stock assessment of Jack Mackerel in the South Pacific, based on data from commercial vessels

A recently developed international fishery for Jack Mackerel (Trachurus murphyi) in the South Pacific has instigated a need for Dutch participation in research into this fish and fishery. A three,year study was therefore commissioned by the Dutch Ministry of Agriculture, Nature and Food Quality and the PFA (Pelagic Freezer trawler Association). Within this study a pilot project for feasibility of stock assessment using acoustic techniques onboard commercial vessels was executed by IMARES and results are presented in this report.
