Contract nr: QLK5-CT-1999-01253
Project type: RS (Research and Technological Development Project)
Starting date: 01-01-2000
Duration: 36 months

Research topic: 5.1.2. Sustainable fisheries and aquaculture

Abstract:
The main objective of the project is to combine geostatistical and Bayesian statistical methods to improve the scientific basis for the management of Atlantic mackerel fisheries. The main tool for their assessment is a trienal survey of pelagic eggs. From these surveys, absolute estimates of spawner abundance are obtained. The fishery is managed by TAC and area closures, based on annual assesmants that fit an age-structured model to cath-age data and the trienial estimates of spawner abundance. In this project, geostatistical and Bayesian estimation methods will be combined to reduce bias in estimates of abundance and to better account for uncertainties. Furthermore, Bayesian decision analysis methods will be used to identify fishery control measures and information gathering and estimation methods that will better ensure that the management methods are adequately robust to uncertainties and conform to the recently adopted precautionary guidelines for fishery management in the CFP.
