In order to consider the possible standardization of the cpue
of the Vigo-Marín trawl
fleet operating in ICES Division VII for its potential use as an abundance index for the assessments of the stocks of megrim (Lepidorhombus whiffiagonis) and anglerfish (Lophius piscatorius
and
L. budegassa) in ICES Divisions VIIb–k and VIIIabd, a series of
preliminary analyses were conducted on data collected on both landings and discards
historic time-series. This document complements the work conducted in Fernández
et
al. (2008). Updated information through to 2010 is now
available, which is taken into
consideration. At the same time, the present document considers the main species
caught by this fleet (L. whiffiagonis, L. boscii,
L. budegassa,
L. piscatorius,
Merluccius merluccius
and
Nephrops norvegicus) in order to try to ascertain whether possible changes
in the directionality of the fleet may have occurred over time. There does not seem to
be a clear change in species composition ...
