Cambios de malla y esfuerzo en las pesquerías multiespecíficas en aguas atlánticas de la península Ibérica

Abstract

Se han realizado diferentes ensayos de cambios de malla y esfuerzo para varias unidades pesqueras de las divisiones VIIIc y IXa del CIEM (Consejo Internacional pqra la Exploración del Mar). Los desembarcos incluidos en este análisis representan la mayoría de las capturas de las especies de merluza, gallos, rapes, jurel, lirio y caballa en la zona sur, definida como unidad de gestión. Están también incluidos tres stocks de cigala de estas divisiones. Dichas especies son las principales especies explotadas por las flotas española y portuguesa, que usan diferentes tipos de artes para explotar diferentes fracciones de las poblaciones. Por esta razón en el presente análisis se utilizaron nueve unidades pesqueras.

Different simulations varying trawl mesh size and effort changes for several fishing units in ICES Divisions VIIIc and IXa were carried out. Landings included in the analysis represent most of the catches in the southern area defined as the management unit for hake, megrim, monkfish, horse mackerel, blue whiting and mackerel. Three Nephrops stocks in Divisions VIIIc and IXa are also included. These species are mainly exploited by Spanish and Portuguese fleets, using various fishing gears to exploit different fractions of the populations; for this reason, nine fishing units were used in the analysis.
