Estudio de las capturas comerciales de Panulirus gracilis (langosta verde) del noroeste del Golfo de Guayaquil (1970-1979) OceanDocs
Cún, M.; Campos, J..
The present work is a study of the fishery of Panulirus gracilis (Green spiny lobster) in the ports of Chanduy, El Real and Anconcito in the north east of the Gulf of Guayaquil 58, 252 specimens caught in the 10 year period 1970 to 1979 were examined. A comparison was made of the sizes of lobsters caught with the established regulation for the explotation of the crustaceans. It was found that both the monthly and annual mean sizes were maintained above the ”minimum permitted length” which is 25 cm total length. Males predominated over females in the ratio 2:1. The percentage of males was 66,5% and of females 33,5%. During the period of the study, berried females of various sizes were frequently found, being most abundant in the months of May, June and July...

Evaluation des stocks et aménagement des pêcheries de la ZEE mauritanienne OceanDocs
Diop, M.; Inejih, C.A.O.; Tous, P.; Failler, P.; Dia, M.A..
Le cinquième groupe de travail destiné à l’évaluation des stocks et l’aménagement des pêcheries de la zone économique exclusive mauritanienne s’est réuni à l’Institut Mauritanien de Recherches Océanographiques et des Pêches (IMROP) du 9 au 17 décembre 2002. Les objectifs de ce groupe de travail étaient d’actualiser les résultats des groupes de travail précédents, en utilisant les nouvelles informations disponibles ; d’établir un diagnostic des différents stocks et pêcheries afin de définir les potentiels de capture ainsi que les caractéristiques de l’effort permissible et d’évaluer l’impact des mesures d’aménagement actuellement en vigueur et identifier les perspectives à venir. Les résultats obtenus ont contribué à la formulation de recommandations...

Floodplain fishery of the lower Sondu-Miriu River with emphasis on the Nile perch (Lates niloticus) (Linnaeus) OceanDocs
Manyala, J.O..
Experimental beach seine surveys in 1990 in the lower Sondu-Miriu River in Kenya indicate a potential catch rate of up to 59.8 kg ha super(-1) hr super(-1). Lates niloticus dominated the catches in the lower reaches (37.5%), while catches in the upper reaches were dominated by Labeo victorianus, Schilbe mystus and Barbus altianalis. L. victorianus contributed up to 84.8% of the catch in the upper reaches by weight. Catches in the floodplain were dominated by Oreochromis niloticus, O. variabilis and Clarias gariepinus, which contributed more than 50% by weight. The size frequency distribution of L. niloticus suggests that larger specimens occur in the river as compared to the floodplain.

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...

Las pesquerías artesanales de la costa del Ecuador y sus capturas en el año 1982 OceanDocs
Herdson, D.; Rodríguez, W.; Martínez, J..
A study was carried out the white fish landings made by the artisanal fisheries in mainland Ecuador in 1982. There were four main groups of landings: the fishery for large pelagic fish, the demersal longline fishery on hard grounds; the set net fisheries for corvina and other medium and large bottom fish and the landings of shrimp by-catch. The fishes caught and their nomenclature; the gears used, the vessels and the fishing communities are briefly described. The landings of with fish by these fisheries in 1082 are given and discussed. The total landings were between 15.000 t and 20.000 t. Of this about 40% was large pelagic fish; 20-30% shrimp by-catch, 20% good quality demersal fish and 10% shark. It should be possible to increase the landings in some...

Les crevettes en Mauritanie, biologie et pêche OceanDocs
Diop, M..
Les prises de crevettes au large de la Mauritanie connaissent une évolution en dent de scie depuis 1989. Les captures déclarées sont de 1112 tonnes en 1987 (dont 1099 tonnes pour le seul second semestre). Elles sont composées à 66% de Penaeus spp (espèces côtières). Les espèces <Parapenaeus longirostrus> et Aristeus spp dont les distributions sont plus profondes ont contribué pour 29 et 5% respectivement des captures totales de crevettes en 1987.

Ocurrencia de gallineta con joroba, Prionotus stephanophrys Lockington (Pisces: Triglidae) en aguas ecuatorianas, y aspectos de su comportamiento, biología y utilización OceanDocs
Herdson, D.M.; Martínez, J..
The occurrence of gurnard Prionotus stephanophrys was studied in the course of a series of fisheries research cruises on the Ecuadorian continental shelf between 1980 and 1985. The species is common in coastal waters south of 1°S . Its abundance is very variable, possibly associated with sea temperatures. Normally densities are between 0.8 and 1.6 t.km-2. The standing stock varies between 13,000 and 150,000 t wich it is estimated can sustain catches of around 4,000 t pet year, and up to 40,000 t in times of great abundance. P. stephanophyrs is found in large shoals on the bottom during the day but a night moves up into mid-water to feed on euphausids. The fish caught had size range of 12 cm to 37 cm, but the majority were between 16 cm and 21 cm in total...

Situación actual de los recursos pesqueros del Archipiélago Sabana-Camagüey, Cuba OceanDocs
Claro, R.; García Arteaga, J.P.; Gobert, B.; Cantelar Ramos, K.; Valle Gómez, S.V.; Pina Amargos, F..
The main objectives of the present study were to describe the historical development of finfish fisheries in the Archipelago Sabana-Camagüey and adjacent northeast region (Cuba), and to assess the current status of fisheries resources. Species and size composition of trawl, trap, and gillnet catches were surveyed, fisheries statistics from fishing enterprises of the area were analysed, and experienced fishermen were interviewed. The historical evolution of catches and changes in fishing effort since 1962 is described. After a growth phase in catches resulting from increasing fishing effort, the fisheries reached a level of overexploitation by the second half of the 70s. The reduction of fishing effort and the establishment of some regulations has...
