USING SATELLITE TECHNOLOGY IMPROVE CHILEAN PURSEINE FISHING FLEET Gayana
Yáñez,E.; Silva,C.; Nieto,K.; Barbieri,M.A.; Martínez,G..
A work of gathering historical fishing (catch, fishing effort, CPUE, characteristics and operation of purseiner fleet) and satellite (NOAA, SeaStar and SeaWind) database of northern Chile, and fishing and oceanographic in situ sampling for validation purpose is made. With this information and the use of geographical information system (GIS) the distribution of pelagic resources and the associated environmental conditions (sea surface temperature, thermal gradients, chlorophyll concentration and wind fields) are analysed in order to develop a probable fishing ground (PFG) index prediction model. A PFG model of anchovy (Engraulins ringens) is operative for the northern Chile. The impact of the use of PFG charts was evaluated analyzing the operational...

La pêche locale aux abords de la Réunion ArchiMer
Biais, Gerard; Taquet, Marc.
The authors deal with the coastal fisheries in the Reunion Island. In a first chapter they describe the geographical environment of this island (volcanism, climate, cyclones, hydrology, currents water masses) which has an influence on fisheries results. The second and third chapter describe the commercial species of the Reunion island (pelagic fishes: Scombridae as Thunnus albacares, Katsunonus pelamis, Euthynnus affinis, Thunnus obesus, Gymnosarda unicolor, Thunnus alalunga, other fishes as Xiphias gladius, Makaira mazara, Istiophorus platypterus. The fourth chapter deals with the fishing gears and the catching methods. The fifth chapter is devoted to fishery economics, financing

Do FADs influence the geographical distribution of dolphinfish (Coryphaena hippurus)? ArchiMer
Taquet, Marc; Reynal, Lionel; Laurans, Martial.
For most fisheries, increasing the local production of pelagic fish is the main objective of Fish Aggregating Devices (fads). This does not rule out the existence of a larger-scale impact, especially on the migratory behaviour of fish. The analysis of data collected during 25 experimental fishing surveys around Martinique between 1995 and 1997 has led to the hypothesis that fads influence the migratory behaviour of young dolphinfish. Unlike recent studies of dolphinfish migration in the Caribbean, which tend to show an annual migration pattern with a seasonal passage through the French West Indies, the experimental fishing surveys done over more than a year on a monthly basis on a single cohort, show that the migratory pattern of part of the regional stock...

Perspectives de developpement des DCP ancres dans les Petites Antilles. L'exemple de trois iles: Guadeloupe, Martinique et Curacao ArchiMer
Reynal, Lionel; Van Buurt, G; Taquet, Marc.
This summary tackles the development of fisheries in the Caribbean using fads. It highlights the principal causes which explain why, in spite of more than thirty years of experimenting, fishing on fads has not developed as much as had been hoped. Whereas the deep-sea production of pelagic fish by the continental countries of the region has considerably increased since the early eighties, that of the Lesser Antilles has grown more slowly. Anchored fads have given the boats of the small-scale fisheries from three islands (Guadeloupe, Martinique and Curacao) access to these pelagic resources. The various modes of development and management of the fads observed in each island are described. The first available data are used to provide some indications of the...

Techniques de pêche utilisées en Martinique pour l’exploitation des grands poissons pélagiques du large ArchiMer
Flament, Margaux; Monet, Nans; Pau, Cedric; Reynal, Lionel.
In the West Indies, artisanal vessels target pelagic fish off the coast using several fishing gears in the same trip, which complicates their codification based on ICCAT references. This paper describes the fishing techniques used in Martinique in exploiting offshore pelagic species. A distinction is made between two métiers, fishing for large pelagic species on free schools or around driftwood and fishing close to anchored fish aggregating devices. These two métiers can be used in the same trip. Fishers can also suspend their use to catch small offshore pelagic species such as flying fish. Each gear enables a species group to be targeted. However, data collection carried out at landing sites does not allow assignment of catches to each of the gears used...

Interannual fluctuations in spring pelagic ecosystem productivity in the Bay of Biscay (northeast Atlantic) measured by mesozooplankton aspartate transcarbamylase activity and relationships with anchovy population dynamics ArchiMer
Bergeron, Jean-pierre; Koueta, Noussithe; Masse, Jacques.
The French part of the continental shelf of the Bay of Biscay (northeast Atlantic) is the habitat of an anchovy (Engraulis encrasicolus L.) population of scientific interest because of its economic importance and the trend towards greater interannual fluctuations in its abundance, particularly as a consequence of variations in recruitment. Each year a 1-month survey of this population and its pelagic environment is undertaken. Among the descriptors of ecosystem function characterized, mesozooplankton aspartate transcarbamylase (ATC) activity is measured with the goal of defining overall productivity of the mesozooplankton communities. Diverse physical forcing factors are responsible for the enhancement of productivity in the Bay of Biscay, and their...

Climate and pelagic fisheries in the Canary and Guinea currents 1964-1993: The role of trade winds and the southern oscillation ArchiMer
Binet, D.
Upwellings off the coasts of western Africa provide abundant but fluctuating marine resources. Sea surface temperature and wind stress, monitored by the ship-of-opportunity observation network, are compared to fishery statistics from 1964 onwards. In the Canary Current, off Sahara and Mauritania, upwellings are mostly wind driven. In the Guinea Current, off Cote d'Ivoire and Ghana, the link with local wind is very weak. In the southern Canary Current, two wind-intensification periods occurred in the early 1970s and from 1986 onwards. On each occasion, Sardina pilchardus landings were multiplied approximately threefold. During the first event, catches of species living at the periphery of the upwelling, Sardinella, Trachurus, Decapterus and Scomber,...

Obervations on the commercial light fishing operation in Ghana OceanDocs
Quartey, R.; Bannerman, P..
Light fishing operations (LFO) in Ghana is concentrated in the three major coastal municipalities of Greater Accra (Tema), Central (Mumford & Elmina) and Western (Sekondi) Regions; these areas have the port facilities for landing of the catch by the larger inshore vessels that operate the purse seine fishery in Ghana and which predominantly operate the light attraction. Currently there are about 250 registered inshore vessels in the country whose sizes range between 39 – 60 feet , only a small fraction are actually working at the moment due to problems with spare parts and operations. Light attraction is the technique of aggregating fish by artificial light; and light fishing is the process of fishing the attracted fish by hooking, gill-netting or by...

Typologie des flottilles industrielles étrangères ciblant les petits pélagiques dans la zone économique exclusive mauritanienne de 1991 à 1999 OceanDocs
Ould Taleb Ould Sidi, M.M..
Deux Analyses Factorielles de Correspondances (AFC), dont l'une est suivie d'une classification hiérarchique, sont réalisées sur les données de capture des petits pélagiques entre 1991 et 1999 dans la Zone Economique Exclusive mauritanienne. Elles permettent de mettre en évidence les déterminants des stratégies de pêche au niveau de cette zone pour les flottilles les plus importantes. Les facteurs comme l'année, les secteurs, la saison et la flottille sont ceux qui expliquent le mieux les variations des captures observées. Les captures augmentent et se diversifient sous l'effet des changements de stratégie et l'arrivée de nouvelles flottilles dans la zone.

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...

Composición por tallas y edades de las capturas comerciales de anchoíta bonaerense obtenidas entre 1990 y 2011 OceanDocs
Hansen, J.E.; Garciarena, A.D..
As part of the research programs performed yearly at the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP, Mar del Plata, Argentina) some important basic data about the commercial fisheries usually included in internal reports are registered. This formal paper is a review and summary of size and age composition estimates of commercial catches (discards included) of Northern Argentine anchovy (34ºS-41ºS) obtained between 1990-2011. The basic data resulting from the examination of 521 samples from fishing vessels included 62,466 fish length measurements and 26,667 valid age readings from which the corresponding 22 annual age-length keys were built. The annual estimates of the individual total length-total weight relation parameters and of...

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...

Situación actual y perspectivas del recurso Sardina (Sardinops sagax) en el Ecuador OceanDocs
González, N.; Santos, M..
Las principales áreas de capturas de Sardina (Sardinops sagax) durante el periodo analizado (1982-1991) estuvieron limitadas al Golfo de Guayaquil entre las 20-70 millas frente a la costa. Las máximas capturas de esta especie se efectúan en los meses de enero-abril (periodo principal) y agosto-octubre. Entre los años 1982-1991, las capturas anuales alcanzaron un máximo de 1,2 millones de toneladas (1985) y un mínimo de 6000 t (1991), el desembarque promedio de la serie analizada fue de 370000 t. Es necesario indicar que después del evento cálido de ”El Niño” (EN) de 1982-1983 la Sardina pasó a constituir la principal especie dentro de las capturas totales efectuadas por la flota cerquera, manteniendo esta tendencia hasta 1989. En general, a partir de 1986,...

El Jurel, especie pelágica de la familia Carangidae, se distribuye en el Pacífico Suroriental principalmente a lo largo de las costas de Perú y Chile entre los 01~'35'N a 55~'S (Chirichigno et al., 1982). Durante el período de 1984-1990 las capturas fueron ocasionales, de poca importancia, reportadas generalmente entre los meses de septiembre-octubre y obtenidas en el extremo sur del Golfo de Guayaquil. En 1991, los resultados del sistema de monitoreo de los puertos pesqueros industriales reportó pequeñas capturas del recurso en enero, las que volvieron a ocurrir a partir del mes de mayo, pero en niveles muy superiores. En 1991 las capturas de Jurel estuvieron comprendidas entre las 64943,8 (mayo) y 74,9 T (diciembre). Durante los meses de mayo, julio y...

Pruebas de aceptabilidad de galletas elaboradas con pecados pelágicos OceanDocs
Goulding, I..
Previous work has established the technical feasibility of producing acceptable shark-base fish biscuits, which were subsequently used for a school breakfast programme in the poorer areas of Ecuador. However, reformulation of the biscuits using chaeper pelagic fish resources (sardine, mackerel and tuna dark meat) was necessary due to changes in the cost and availability of shark. This paper describes a datailed examination of the organoleptic quality of the pelagic-fish based biscuits, and the results of acceptability test undertaken with children attending 3 schools in the marginal areas of Guayaquil. For the first part, 5 panelists selected from staff at Instituto Nacional de Pesca, rated each of the 3 types of biscuit using 5 rating scale describing...
