Actividad de la flota sardinal española en África occidental. Aspectos biológicos de la sardina, Sardina pilchardus (Walbaum, 1792), dinámica y evaluación del recurso

Abstract

La gran riqueza pesquera de la costa noroccidental africana, además de su proximidad a las costas españolas y la gran tradición pesquera de este país, ha dado lugar a que la flota española, principalmente la procedente de puertos canarios y andaluces, desarrollaran su actividad en dicha zona desde tiempos pasados, bien artesanalmente, sobre todo en su inicio, o de forma semi-industrial o industrial propiamente dicha en las últimas décadas, siendo los recursos de mayor interés para esta flota los crustáceos: gamba Parapenaeus longirostris (Lucas, 1846); alistado Aristeus varidens Holthuis, 1952; moruno Aristaemorpha foliacea (Risso, 1827); carabinero Plesiopenaeus edwardsianus (Johnson, 1867); merluzas: merluza blanca Merluccius merluccius (Linnaeus, 1758); merluza negra Merluccius polli Cadenat, 1950 y merluza senegalesa Merluccius senegalensis Cadenat, 1950; cefalópodos: pulpo Octopus vulgaris, Cuvier 1797; choco Sepia spp. y calamar Loligo vulgaris Lamarck, 1798; otros peces demersales: chopa; sama; bocinegro Pagrus pagrus Linnaeus, 1758; burro Plectorhinchus mediterraneus (Guichenot, 1850), etc.; peces pelágicos costeros: anchoa Engraulis encrasicolus (Linnacus, 1758) y la sardina Sardina Pilchardus (Walbaum, 1792), que es la especie más abundante, suponiendo sus capturas más del 50 % del total desembarcado por la flota española que desarrolla su actividad en esta zona. Esta memoria plantea como objetivos principales, tomando como punto de partida la serie histórica que abarca el periodo comprendido entre los años 1976 y 1991, analizar el desarrollo de la pesquería prácticamente desde sus comienzos hasta la actualidad, describiendo para ello la actividad y evolución de la flota sardinal española que faena en África occidental; describir los parámetros biológicos que definen a la sardina distribuida entre 22° N y 32° N, y finalmente, presentar la última evaluación realizada para la determinación del grado de explotación del recurso a través de la aplicación de la técnica analítica denominada Análisis de Cohortes, aspectos todos ellos resumidos de la siguiente manera : [Ver Resumen completo en pdf].

The great fishing wealth of the northwest african coast, in addition to its proximity to the Spanish coasts and the large fishing tradition of this country, it has given cause for that the Spanish fleet, mainly the originating from Andalusian and Canary ports, developed its activity in such zone from past times, well artisanaly, above all in its beginning, or in a way semi-industrial or industrial properly said In the last decades, being the main target resources for this fleet the crustaceans: deepwater rose shrimp Parapenaeus longirostris (Lucas, 1846); striped red shrimp Aristeus varidens Holthuis, 1952; giant red shrimp Aristaeomorpha foliacea (Risso, 1827); scarlet shrimp Plesiopenaeus edwardsianus (Johnson, 1867); hakes: european hake Merluccius merluccius (Linnaeus, 1758); benguela hake Merluccius polli Cadenat, 1950 and senegalese hake Merluccius senegalensis Cadenat, 1950; cephalopodes: octopus Octopus vulgaris Cuvier, 1797; cuttlefish Sepia spp. and squid Loligo vulgaris Lamarck, 1798; other demersal fish: black seabream; common seabream Pagrus pagrus Linnaeus, 1758; rubberlip grunt Plectorhinchus mediterraneus (Guichenot, 1850), etc.; coastal pelagics fish: anchovy, Engraulis encrasicolus (Linnaeus, 1758) and the sardine Sardina pilchardus (Walbaum, 1792) that it is the species most abundant, representing its catches more than 50 % of the total landings of the Spanish fleet. This report outlines as main objectives, taking as starting point the historical series that include the period between the years 1976 and 1991, to analyze the development of the fishery practically from its beginning until the present time, describing for this the activity and evolution of the Spanish sardinal feet that fish in Western Africa; to describe the biological parameters that define the sardine distributed between 22ºN and 32ºN, and finally, to present the last assessment carried out for the determination of the degree of explotation of the resource through the application of the designated analytical technique "Cohorts Analysis", aspects all they summarized in the following way: [See full Summary pdf].
