Analysis of gear interactions in a hake fishery: The case of the Gulf of Lions (NW Mediterranean)
Provedor de dados: 5
Autores: Aldebert, Yvonne; Recasens, Laura; Lleonart, Jordi.
The hake of the Gulf of Lions is the most important target species of the demersal fishery. It is exploited by four types of gear (two trawls, gillnet and longline) used by two countries (France and Spain). Some analyses of its dynamics, based on 19 88 length frequency data by gear, have been performed. These analyses consisted in a VPA (Virtual Population Analysis). phis a Y/R (Yield per Recruit analysis) carried out on two parameter scenarios by sex, under a steady state hypothesis (with constant recruitment). Some estimates of biomass and exploitation level were obtained, and sensitivity to the biological parameters and interaction between types of gear were studied. As a main conclusion, it can be seen that the types of gear fishing mainly small...

Comparison of methods for stock assessment of European hake Merluccius merluccius in the Gulf of Lions (Northwestern mediterranean)
Provedor de dados: 5
Autores: Aldebert, Yvonne; Recasens, Laura.
European hake Merluccius merluccius is the main commercial demersal species in the Gulf of Lions (Northwestern Mediterranean). This fish is exploited by French and Spanish trawler fleets and by small-scale fisheries using gillnets and longlines. Data on landings and the demography of catches by type of gear are now available for the period 1988-1991. The assessment of the hake stock was carried out using methods of virtual population analysis (VPA), or cohort analysis, based respectively on mean pseudocohorts and cohorts by age. The results of these VPA were then analysed and compared from a methodological point of view. The general results have confirmed previous studies with regard to the level of exploitation of the species. The two methods gave quite...
