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.

Estudios bionómicos del bentos de la plataforma bonaerense y su relación con el resto de la plataforma continental argentina. OceanDocs
Roux, A..
The macrobenthic assemblages of the Buenos Aires Province(Argentina) continental shelf were studied from samples collected by the R/V Capitán Cánepa and R/V Capitán Oca Balda along a transect from38 m to 218 m depth. Three faunistic areas were determined,corresponding to the coastal, central and external shelf, inhabited by species originated from the Argentine and/or Magellanic Zoogeographical Provinces. These results confirm the presence of different ecological areas in the Argentine continental shelf. Mussel (Mytilus edulis platensis) beds, red porgy (Sparus pagrus) fishing ground and the Argentine-Uruguayan Common Fishing Zone (CFZ) demersal fishing grounds at the continental shelf of Buenos Aires Province were also analyzed to increase the knowledge...

Áreas potenciales de descarte de merluza para la actividad de la flota comercial argentina OceanDocs
Dato, C.V.; Villarino, M.F.; Cañete, G.R..
To improve the quality of the resource assessment it is necessary to estimate discards and quantify them applying an adequate methodology. The purpose of this work is to detect areas where the activity of the commercial fleet coincides with zones of high concentration of juveniles because they are potential discard areas. To establish possible seasonal and/or interannual variations, length distribution data derived from hake research surveys carried out on board of INIDEP vessels during the 1986-1993 period were analyzed. Samples were grouped per statistical rectangle on the basis of catch weighted average and mean, variance, skewness and kurtosis were calculated. The resulting parameters were subjected to a cluster analysis using the Euclidean distance...

Scelzo, M.A.; Martínez Arca, J.; Lucero, N.M..
The seasonal variation of diversity, density and biomass of the main species of the bentho-demersal fauna present in the 'prawn-shrimp' fishing grounds in the coastal sector between Cabo Corrientes and Torreon del Monje, Mar del Plata (38 degree S-57 degree W), Argentina, was studied. The quali-quantitative information obtained allowed to know the fluctuations of the bentho-demersal components of the community. The study included the annual cycle between April 1998-April 1999. Monthly samples at different depths (4-10 m) and distance from the coast (500 and 1,000 m) were obtained in two stations using a bottom net. Sampling in each station lasted 15 minutes and covered 2,400 m super(2). Number of specimens and weight for each species were recorded....

Pesquerías de bivalvos: mejillón, vieiras (tehuelche y patagónica) y otras especies OceanDocs
Ciocco, N.F.; Lasta, M.L.; Bremec, C..
Fisheries of the mussel Mytilus edulis platensis, the tehuelche scallop Aequipecten tehuelchus and Patagonian scallop Zygochlamys patagonica are described. Information about catches of purple clam Amiantis purpurata in San Matias Gulf, mussel Aulacomya ater ater and hard shell clam Ameghinomya antiqua in San José Gulf is also presented. Regarding mytilus fishery, it is observed that the main catches were situated in Faro Querandí and Quequén beds (Buenos Aires Province, Argentina), where high densities occured in an area between 35 and 60 m depths. Those beds were exploited until the production was no more commercially interesting. The tehuelche scallop is a very well known resource from the Argentine Sea and its fisheries from San Matías and San José...

Vieira patagonica (Zygochlamys patagonica King & Broderip, 1832): una nueva pesquería en la plataforma continental argentina. OceanDocs
Lasta, M.L.; Bremec, C..
Patagonian scallop (Zygochlamys patagonica King Broderip, 1832): A new fishery in the Argentine continental shelf. We present preliminary information on a new fishery of patagonian scallop (Zygochlamys patagonica King Broderip, 1832) in the Argentine Continental Shelf. A research program was conducted jointly by INIDEP and a fishing company during 1995 with the F/V Erin Bruce. The vessel, fishing equipment and processing on board are described. A total of 7235 fishing tows were performed during 246 days at sea. Seven new beds were located between 38º 50' S and 42º 30' S, along the 100-m isobath. Beds are discrete. Differences in the size structure by bed suggest that recruitment consists of sporadic pulses. Proportion of scallops and invertebrate by-catch...

Evaluación pesquera del bacalao austral (Salilota australis) del Atlántico Sudoccidental OceanDocs
Wöhler, O.C.; Cassia, M.C.; Hansen, J.E..
Information about the austral cod Salilota australis caught in the Patagonian shelf including the area around Malvinas Islands (SW Atlantic)as well as some data from annual research surveys carried out as of 1992 to 1998 were analyzed. On this basis, the fishery was studied and the abundance of the stock inhabiting the area under Argentine control was estimated. To calculate the optimum yield as a function of both age-at-first catch and fishing mortality, the Yield-per-Recruit model was used. Some biological reference points were also identified and an exploitation strategy based on low risk of collapse recommended. Austral cod landings, although small, showed an increasing trend as of 1990 that reached a maximum of 14,900 tons in 1998. Most of the catches...

Crustáceos Decápodos y Estomatópodos asociados a la pesquería del langostino patagónico Pleoticus muelleri (Bate, 1888) en el golfo San Jorge, Argentina OceanDocs
Roux, A.; Piñero, R..
The analysis of the data obtained in five research cruises carried out during the year 2000 allowed to describe the composition, structure and distribution of decapod and stomatopod crustaceans of the benthic communities of the San Jorge Gulf associated to Patagonian red shrimp fishing grounds. Results show that decapod and stomatopod crustaceans account for 71% of the total crustacean species registered in the benthic community. Munida subrugosa is the species that presents the highest values of relative abundance, frequency of occurrence and relative importance index. The feeding habits of Libidoclaea granaria, Lithodes santolla and Peltarion spinosulum and food availability in the San Jorge Gulf fishing grounds explain the high frequency of occurrence...

Consideraciones sobre la explotación del mejillón (Mytilus platensis)en la costa bonaerense. Resultados de la campaña de prospección del "Banco Faro Querandí" (junio 1981) OceanDocs
Lasta, M.L.; Parma, A.M.; Pascual, M.S.; Zampatti, E.A..
The fishing of the mussel (Mytilus edulis platensis)off the Buenos Aires coast was alternatively carried out over two main grounds: "Faro Querandí" and "Quequén". The fluctuations of fishing periods on these grounds must have been determined by economic considerations. An abandoned bed may be considere, for practical purposes, depleted.The understanding of the dynamics of this spatially distributed stock could enable us to link more closely the biological cycles with those of the fishing activity. Rotative fishing is suggested as a managment strategy for this fishery.

Estudio de algunos aspectos del ciclo vital de la merluza de cola Macruronus magellanicus, Lonnberg, 1907. OceanDocs
Giussi, A.R..
Long tailed hake Macruronus magellanicus, is a demersal fish,distributed in the SW Atlantic Ocean, in Malvinas Current waters,from 36° and 55°S, mainly between 50m and 200m depth. The species is also distributed in Chilenian waters in the Pacific Ocean, being caught in the Magellan Strait and the Beagle Channel. Age determination was estimated with the sagittae otoliths, in which only one ring is formed during the year. Growth parameters were calculated directly and with back calculated methodology, no differences were observed between the results. Differences in growth sexes were evident from 3 years old. The oldest age observed was 13. Different distributional areas of adults through out the year could suggest a migratory movement in northern waters of...

El proceso de pesca en la explotación de la vieira patagónica (Zygochlamys patagonica) y las respuestas espacio-temporales de las poblaciones OceanDocs
Bogazzi, E..
Several attributes of populations of sedentary organisms differentiate benthic fisheries from those approached by the classic theory, inspired by fin-fisheries. The assessment and management of sedentary resources require the application of non-conventional methodological tools. Understanding the fishing process, in particular, is central to the analysis and management of those fisheries. The purpose of this thesis was to investigate the fishing process and its impact on stocks of the Patagonian scallop (Zygochlamys patagonica) fishery. Data and information utilized included: (i) historical data from commercial vessels and experimental fishing; (ii) positional, catch and effort data, and additional information corresponding to fleet activity between 1995...

The faunistic composition of invertebrate by-catch associated with the Patagonian scallop Zygochlamys patagonica fishery before its development were studied. Analyzed material was sampled from catches performed in different beds with the F/V Erin Bruce during 1995, all of them in undisturbed areas, in the Argentine continental shelf. Macrofaunal species were identified, weighted and percentages of presence estimated. By-catch invertebrate species were determined for every bed, mainly invertebrates without present commercial value. This baseline information is considered a useful tool to detect structural changes in the benthic communities in relation to the conservation of possible substrates of recruitment of this resource and to estimate the evolution of...

The Argentine-Uruguayan Common Fishing Zone and the problem of the hake catch quota allocation. The aim of this paper is to present the problem of the catch quota in the shared zone and the proposals related to the maximum catch from 1976 to 1998. The state of the population which inhabits the Common Fishing Zone and north of 41°S is diagnosed, concluding that the total biomass has declined in this period and the spawning stock biomass is under the allowable biological catches. In addition, the catch per unit effort (CPUE)of the commercial fleet has a declining tendency and the total effort is duplicated. Biological population characteristics are presented: reproduction, feeding, nursery grounds and closed areas to protect juveniles. Proportional...
