Abstract

This paper gives a description of the horse mackerel ontogenic migrations along the Iberian Atlantic coast, based on bottom-trawl survey datacovering the period 1985–2003. The estimates of abundance and mean age from each haul were modelled as a function of year, area and depthand graphs were made showing the proportion of the abundance indices in each area of the coast for each year class. The hypothesis of ontogenicmigrations of horse mackerel along the Iberian Atlantic coast is supported by the results obtained. These migrations seem to have two directions:one along the coast line and another perpendicular to the coast line, through different depths. The fish migrating through the Spanish area, fromBiscaytoNorthGalicia,areprobablycomingfromthestockdistributedfromNorwaythroughthewestoftheBritishIsles,withasouthernboundaryaround Cape Finisterre. Off the Portuguese coast, most year classes seem to recruit to the northwest area, moving progressively to south, and insome cases, after reaching 7 years of age, returning back to northern waters., Sí

Abstract

Spanish Oceanogrnphic Institute (IEO) and Portuguese Research Inistitute (IPIMAR, ex-INIP) using their research vessels "Comide de Saavedra" and "Noruega" have conducted groundfish surveys in Spanish and Portuguese waters. The results of these surveys have been reported to the relevant ICES Working Groups, communicated to ICES Annual Conferences and/or published in journals of bioiogy and flsheries. Data collected from groundfish surveys were also the basis to carry out assemblage studies and to several advices to the Spanish, Porttuguese and European fishery administrations concerning the implementation of technical measures for fish stock management. This communication intends to give information about the past, the present and the future of these surveys, concerning objectives, methodology and publications. Critical aspects and solutions to improve some aspects are presented.

Abstract

This paper concerns Hake fishery from the North of Galicia (Spain) to the South of Portugal. It represents one more attempt in obtaining more informations about the exploitation state of hake stock in this area. The aim of this study is to assess the immediate and long-term effects in this fishery with different fishing strategies. The models used were the following: a) increases in mesh-size: - Gulland (1961), Jones (1974), Ricker (1975), Cadima (1976,1978). b) increases in mesh-size and changes in fishing effort: - Jones (1974) and Ricker (1975). To apply such methods we used the data concerning the mean catches (from 1974 to 1977) belonging to the Galician and Portuguese fleets., Ce travail concerne la pêcherie du merlu de la côte nord de la Galice (Espagne), jusq'au sud du Portugal. Il répresente un essai en plus pour améliorer notre connaissance sur l'état d'exploitation du stock du merlu dans cette même region. Le but de cet étude c'est l'évaluation des effects immédiats et a long terme sur la pêcherie selon des stratégies de peche différentes. Les modeles appliqués ont été les suivants: a) pour les accroissements des maillages: Gulland (1961), Jones (1974), Ricker (1975), Cadima (1976,1978). b) pour les variations de l'effort et augmentations des mail lages: Jones (1974) et Ricker (1975). Pour l'application des méthodes mentionnées, nous avons utilisé les données rélatives a la moyenne des captures réalisées par les flotilles espagnole (Galicienne) et portugaise, pendant la période 1974-77.
