Methods of approach on the population dynamics of hake (Merluccius merluccius) in Majorca (NW Mediterranean)

Oliver P., Massutí E., Reñones O.

Hake (Merluccius merluccius) is, like in other Mediterranean fisheries, one of the main target species in the trawl fishery developed off Majorca. This paper describes the results obtained with VPA and Y/R analysis for this species in the area, using cohort and pseudocohort assessment methods. The estimates of mortality and recruitment values obtained by means of different approaches are analysed and compared. Another methodological trial has been oriented towards the comparison of the Y/R values obtained when using an average pseudocohort over several years and annual pseudocohorts. In all cases, the results have shown a high level of fishing effort and an inadequacy of the exploitation pattern which is applied to hake stock in Majorca.
