The Colombian deep sea shrimp fishery is carried out by vessels with double bottom trawl fishing gear. There is a wide variety in the catch composition species, in which many of them have a wide distribution depth range. Fifty four fish species of 35 families, 11 crustacean species of 11 families, and one mollusk species were identified. Some holothurians, gastropods, echinoderms and other mollusks also appeared occasionally. The joint analysis of the current and former studies determined 85 species in the catch composition of this fishery. The Colombian bottom trawl fishery is actually using the turtle excluder device as the only technical adaptation of the fishing gear to reduce the bycatch turtles, but seems to exclude other big size commercial bycatch....

Provedor de dados: 5
Autores: Latrouite, Daniel; Morizur, Yvon.
French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

Changes in the catch composition of artisanal fisheries attributable to dolphin depredation in a Mediterranean marine reserve
Provedor de dados: 5
Autores: Rocklin, Delphine; Santoni, Marie-catherine; Culioli, Jean-michel; Tomasini, Jean-antoine; Pelletier, Dominique; Mouillot, David.
There is increasing evidence from previous studies, and from fishers' observations, that coastal dolphins use fishing nets as an easily accessible feeding source, damaging or depredating fish caught in the nets. This study investigates the impact of dolphin depredation on artisanal trammelnets by analysing the catch composition of 614 artisanal fishing operations in the Bonifacio Strait Natural Reserve (France). Common bottlenose dolphins (Tursiops truncatus) attacked, on average, 12.4% of the nets and damaged 8.3% of the catch. However, attacked nets were characterized by statistically significantly higher catch per unit effort than unattacked ones. Catch composition also differed significantly after dolphin attacks; bentho-pelagic fish were more...

Dinámica y manejo de la captura incidental de peces en la pesquería del langostino patagónico (Pleoticus muelleri)
Provedor de dados: 20
Autores: Góngora, M.E.
This work characterizes the composition and dynamics of the incidental catch in the patagonian shrimp (Pleoticus muelleri) fishery, with special emphasis on the bycatch of common hake (Merlucius hubbsi). The Observer Program coordinated by the Chubut Province (Argentina) and used to monitor the fishery is evaluated. The factors that explain the variability of hake bycatch rates are analyzed, different statistical estimators are evaluated and possible strategies for controlling bycatch are discussed. The study is centered on the double-otter-trawl freezers, responsible for 75 percent  of the Argentine shrimp landings. This fleet operates in San Jorge Gulf, in waters under the jurisdiction of the provinces of Chubut and Santa Cruz, and in waters of the...

Ocurrencia de gallineta con joroba, Prionotus stephanophrys Lockington (Pisces: Triglidae) en aguas ecuatorianas, y aspectos de su comportamiento, biología y utilización
Provedor de dados: 20
Autores: 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...

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...

Floodplain fishery of the lower Sondu-Miriu River with emphasis on the Nile perch (Lates niloticus) (Linnaeus)
Provedor de dados: 20
Autores: 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.

Las pesquerías artesanales de la costa del Ecuador y sus capturas en el año 1982
Provedor de dados: 20
Autores: 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...

Autores: 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...

Seychelles demersal fishery an analysis of data relating to four key demersal species
Provedor de dados: 20
Autores: Mees, C. C.
Seychelles demersal fishery is described based on historic catch and effort data, and on biological studies of four key species: Batrican (Pristipomoides filamentosus), Job Gris (Aprion virescens), Bourgeois (Lutjanus sebae), and Maconde (Epinephelus chlorostigma).  During the period 1985 - 1990 demersal species formed on average 33_310= of the total annual landings of the local fishing fleet.  Schooners and whalers were the most important boat types engaging in this fishery, and more recently, a mother ship dory fishing operation. Demersal species constituted 77_310= of all local fish exports over this period. In 1990 approximately 2,000 tonnes of demersal species were landed of which 500 tonnes were exported.  Lutjanids comprised 62_310= of the demersal...

La pêche industrielle des espèces pélagiques côtières en Mauritanie de 1979 à 1985 - Deuxième partie : la Pêche au chalut pélagique
Provedor de dados: 20
Autores: 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...
