Evaluación del recurso abadejo y recomendaciones sobre su explotación a partir del año 2002 OceanDocs
Cordo, H.D..
Ling (Genypterus blacodes) resource was assessed by means of an age structured production model fitted with stock abundance indices from catch per unit effort data (CPUE) obtained from the commercial fishing fleet. Reproductive stock was assessed in the same way with CPUE data from the fishery research vessel. A short-term analysis of collapse risk as a function of 1999 and 2000 fishing mortalities was carried out with the results, and also a long-term analysis with the assumption of a variable fishing mortality (F) with two recruitment hypotheses. Results show that the present state of the Ling resource has worsened with respect to the last assessment. Considering the best of all cases, the Br/Kr relationship decreased from 0.55 to 0.33, indicating that...

Evaluación del abadejo (Genypterus blacodes) en el Atlántico Sudoccidental por medio de modelos de producción dinámicos. OceanDocs
Cordo, H.D..
Two dynamic production models were applied to assess the status of ling Genypterus blacodes stock in the SW Atlantic. The simplest (biomass dynamic model)and a more complex one (structured production model) were fitted with commercial CPUEs as abundance indices. Ling is one of the most important demersal fishes in Argentine waters. It is a demersal fish found between 35°and 55°S that shows the highest concentration in summer, between 42°and 48°S. In winter, schools disperse over the whole range of distribution. Argentine ling fishery started developing in 1986 when catches surpassed 15000 mt/year to stabilize, in recent years, at around 23000 mt/year. The species is caught mainly as by-catch by trawlers with bottom net that direct their effort to hake...

Los recursos pesqueros demersales del Mar Argentino. Parte I. Evaluación de la biomasa (Standing stock)de la merluza común (Merluccius hubbsi)y de la merluza austral (Merluccius polylepis)en el área de su distribución estival OceanDocs
Simonazzi, M.A.; Otero, H.O..
The present paper deals with the standing stock (Pw1)of the common hake (Merluccius hubbsi)and the austral hake (Merluccius polylepis), using the swept are method (Alverson, 1971)and with the Potential Yield (Cmax)using the Gulland (1970)method. The standing stock of the common hake was 2.642.715 tons. the highest concentrations of this specie were distributed over 12.348 nm² (13 o/o of the toal distribution area)with 1.178.843 tons. This area was located between 41° and 45° of south latitude and between the coast and 100 m of bottom depth in the Patagonian Shelf. The other 1.463.872 tons were distributed over a wide area of 82.727 nm².

La pêche industrielle des espèces pélagiques côtières en Mauritanie de 1979 à 1985 - Deuxième partie : la Pêche au chalut pélagique OceanDocs
Josse, E..
Après la mise en place de la ZEE à 200 miles en 1978, la pêche au chalut pélagique s’est développée très rapidement en Mauritanie. Avec un effort de pêche pratiquement multiplié par 10 entre 1979 et 1983. De 1979 à 1986, sept pays ont participé plus ou moins régulièrement à l’exploitation des ressources pélagiques côtières de la ZEE mauritanienne, avec des chalutiers pélagiques de gros tonnage. Trois pays : l’Allemagne de l’Est, la Roumanie et l’URSS ont réalisé, selon les années, entre les ¾ et la totalité de l’effort total, et de 80 à 100% des captures totales. Les captures totales ont été maximales en 1983, avec 470 000 tonnes. Après une baisse en 1984 elles se sont stabilisées en 1985 et 1986 entre 450 000 et 460 000 tonnes. La composition spécifique...

Abondance relative et estimation de la biomasse des petits pélagiques des eaux tunisiennes OceanDocs
Ben Abdallah, L.; Hattour, A.; Guennegan, Y..
Deux campagnes de prospection sur les petits pélagiques s'inscrivant dans le cadre du Programme National Mobilisateur (PNM), "Evaluation de ressources pélagiques et démersales des eaux tunisiennes" (1996-1999) ont été menée en étroite collaboration avec l’Institut Français de Recherche et d’Exploitation de la Mer (IFREMER). Ces campagnes ont pour objectifs de préciser l'abondance relative des petits pélagiques et leur variabilité spatiaux-temporelles mais également de quantifier les potentiels exploitables des stocks des animaux aquatiques préalablement définis, et surtout de familiariser l’équipe des scientifiques tunisiens, aux méthodes numériques et informatiques utilisées en participant à la lecture des échogrammes et aux traitements des données des...

Talla de primera madurez del abadejo (Genypterus blacodes) en el Atlántico Sudoccidental. OceanDocs
Cordo, H.D.; Machinandiarena, L.; Macchi, G.J.; Villarino, M.F..
The length at first maturity (Lm50. ) and the maturity ogive are very important parameters in stock assessment. In this paper the ling Genypterus blacodes females Lm50. is estimated with frequencies of mature fish determined by microscope diagnosis of ovaries collected during the spawning season (SW Atlantic). The Lm50. of ling was estimated at 70.5 cm of total length (TL), which corresponds to an age of 4.5 years. The maturity process occurs between 63 and 78 cm TL (between 3.7 and 5.4 years).

Estado de explotación del recurso besugo (Epigonus crassicaudus) en Chile OceanDocs
Wiff, R.; Quiroz, J.C.; Tascheri, R..
The exploitation status of cardinalfish (Epigonus crassicaudus) yielded in Chile between 33° to 41°S was analyzed. An indirect assessment was performed between 1997 and 2003 through size-structured model with a transition matrix defining the changes among sizes. The model was calibrated using size structures, official landings, catch-per-unit of effort (CPUE) taken from commercial fishing logbooks and standardized by generalized linear models (GLM). After 7 years of an intense fishery activity, we concluded that the cardinalfish resource in Chile is on the recruitment overfishing limit. On 2003, the spawning biomass with respect to the virginal spawning biomass is close to 40%. The biological references points (BRP) based on spawning per recruit biomass...
