Les Sars Deplodus sargus (Linne 1758) du Golfe du Lion: croissance et caracteristiques des debarquements aux criees de Sete et du Grau-du-Roi. ArchiMer
Man-wai, Rabenevanana; Quignard, Jean-pierre.
Age and growth of seabream D. sargus in the Gulf of Lions (Mediterranean Sea) were examined using scale reading. Growth was expressed by the von Bertalanffy's equation based on the estimation of total lengths at the time of annual ring formation. The growth in weight and the length-weight relationship were calculated for both sexes separately and combined during and after spawning periods. Preliminary investigations on the characteristics of commercial catches (from Sete and Grau-du-Roi commercial fishing grounds) were also carried out.

Seychelles artisanal fisheries statistics for 2002 OceanDocs
Azemia, R.T.; Robinson, J..
(1). During 2002 an estimated total of 4915 tonnes of fish was landed on Mahe, Praslin and La Digue by 374 fishing boats. 83.1% of the total catch was landed on Mahe alone. The total catch increased by 625 tonnes compared to 2001, and the number of boats operating decreased by 3 over the same period. (2). The most important species groups landed (greater than 5% of the total catch) were carangues (41.5%), job (12.4%), capitaine (6.8%), becune (6.1%), maquereau doux (5.7%) and bourgeois (5.7%). (3). Peak landings occurred in October (576.5 MT) and the lowest catch was recorded in January (222.51 MT). The average catch per month was 409.6 tonnes. (4). Seasonal variation in catches of demersal species was less marked compared to previous years. The mean...

Structure démographique des captures des sardiniers Dakarois en 1981 OceanDocs
Lopez, J.; Sow, I..
Ce document de travail présente la structure démographique des captures des sardiniers dakarois en 1981. Les sardiniers basés à Dakar en 1981, étaient au nombre de 15. Les captures réalisés par ces unités, les efforts de pêche mis en oeuvre de même que les rendements obtenus pour chaque espéce ont déjà été récapitulés dans l'archive n°113. Pour les principales espèces débarquées, les distriibutions de fréquence de taille sont présentées mensuellement. Les résultats obtenus sont exploités pour les études de biologie et de dynamique des populations; ils feront l'objet de publications.

Ce document de travail presente la structure démographique des captures des filets tournants sur la Petite Côte : Mbour et Joal, en 1981. Les données de base prises et fréquences, ont été traitées séparément pour chacun des deux centres. En ce qui concerne les statistiques pour chaque centre les données relatives aux sennes tournantes et les filets maillants cncerclants sont en cours de publication et exploitées partiellement. Pour les fréquences, toutes les mensurations effectuées ont été regroupées dans un fichier unique comprenant les données de Mbour et de Joal, filets maillants encerclants et sennes tournantes réunis. Le regroupement des mensurations des deux centres tient au fait que les pêcheurs travaillent dans. les mêmes secteurs capturant donc...

Sampling the catch of fishing trawlers OceanDocs
Okpanife, M. O..
This paper discusses the sample the sample design and estimation method for sampling the commercial catches of fishing trawlers. The result of the application of the design to Nigerian Fishing Trawlers in 1981 is presented. The conclusion that Nigerian Trawlers and not catching undersized fish as at 1981 is valid only on the assumption that there is no dumping of undersized fish at sea.

Dinámica de la flota comercial argentina dirigida a la pesquería de merluza (Merluccius hubbsi) en el Mar Argentino. Periodo 1990-1997 OceanDocs
Dato, C.V.; Villarino, M.F.; Cañete, G.R..
Since 1990, the Argentine commercial fleet directed to hake (Merluccius hubbsi) has obtained more than 70 of catches South of 41°S while to the North of this latitude the activity concentrated between 39°S and 41°S Argentine Sea, SW Atlantic. Bearing in mind the different characteristics of ice-chilling and freezer fleets, their activities were analyzed separately. Considering the relative percentages of catches declared in fishery statistics, the dynamics of each fleet is described per quarter and year. Special reference is made to 1997 when a closed area to protect juveniles was introduced between 44°S-47°S and 62°W-65°W. The freezer fleet activity, concentrated South of 41°S, especially South of 43°S, was stable throughout the period. It grouped around...

Estratificación de la flota industrial de buques fresqueros y estimación de los rendimientos OceanDocs
Bertolotti, M.I.; Pagani, A.N.; Hernandez, D.R.; Buono, J.J..
In order to increase knowledge about the ice chilling fleet and to explain the relationship between structural variables and yields, a simplified model was developed. The fleet was classified in three homogeneous strata. Stratum I includes the smallest ships, with a catch composition equal to that of the large coastal fishing vessels. The stratum yields decreased in 1997 and 1998. Strata II and III have common hake as the main target of catches. Yields of those strata showed a continuous decrease as of 1994/1995. Therefore, the species was replaced by other fish originally caught by other fleets. These two last strata are more vulnerable to overfishing of traditional coastal and demersal fisheries.
