Les Sars Deplodus sargus (Linne 1758) du Golfe du Lion: croissance et caracteristiques des debarquements aux criees de Sete et du Grau-du-Roi.
Provedor de dados: 5
Autores: 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.

Autores: 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...

Autores: 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...

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...

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...

Autores: 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...

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.

Autores: 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
Provedor de dados: 20
Autores: 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...

The different aspects of the benthic assemblages at the Patagonian scallop beds in the Argentine Sea (SW Atlantic) were studied. The Patagonian scallop (Zygochlamys patagonica) is a commercial species distributed in the Magellanic Biogeographic Province, and has been commercially exploited since 1996. Temporal and spatial studies were performed in the community composition between 39°50'S and 36°15'S, and between 1998 and 2003, concluding that the species association was persistent after more than 7 years of trawling activities. Species composition in an exclusion area (closed to scallop fishing) did not differ from surrounding fished areas during the studied period, showing only a higher scallop biomass. ABC curves showed a pattern coincident with a non...

Movements pattern records of the Mar del Plata inshore fishing fleet during the 1997/98 and 1998/99 chub mackerel fishing seasons (October-January) allowed to observe that there is coincidence between the decrease of the 1983-1997 catches with respect to years previous to the 1975/76 "critical season" and a reduction of the inshore fleet fishing grounds which modifies accessibility of the fleet to the chub mackerel schools. Biostatistical and gonadal development results obtained in the Mar del Plata area (i.e., presence of adults during almost the whole fishing season which overlaps with the spawning season) do not differ significantly from those obtained during previous fishing seasons. As recommended in previous papers, chub mackerel fishing operations...

Il montre ensuite sue l'autre facette de taille de ce dispositif est incarnée par la symbiose qui existe entre les différents acteurs impliqués; ce qui a valu à ces derniers, sur la bse d'une synergie des interventions et d'une complémentarité d'actions, de bien se déployer sur le terrains, pour permettre aux communautés de pêcheurs des quatre (4) sites pilotes du Programme (Ouakam, Ngaparou, Foundiougne, Bétenti), d'identifier leurs premières initiatives locales de cogestion et de présenter leurs premiers...

Dans le cadre du Programme Girmac, une mission sénégalaise a silloné du 1er au 30 septembre 2005 trois pays de l'Asie du Sud-Est (Japon, Thaïlande et Philippines) pour s'imprégner de leurs expériences en matière de co-gestion des pêcheires artisanales. Il ressort au total que chaque pays a sa vision et sa pratique de la co-gestion des pêcheries, celle-ci étant un processus dynamique qui doit être adapté à la culture des communuatés qui se proposent de l'adopter

Catch records of flatfishes obtained in exploratory cruises and in the existing literature in the geographical area between 34°S and 55°S in the Western SOuth Atlantic were analyzed to elaborate maps of the distribution of the most common flatfish species in this area. Data from commercial fleet landings at Mar del Plata Harbor were used to analyze the distribution and areas of resource concentration. The flatfish most frequently found in this study area belong to three families: 1. Paralichthidae, with the species: Thysanopsetta naresi, Paralichthys orbignyanus, Paralichthys patagonicus, Paralichthys isoceles, Xystreurys rasile. 2.-Pleuronectidae, with the species: Oncopterus darwini. 3. Achiropsettidae with: Mancopsetta maculata, Mancopsetta milfordi,...

Basic aspects concerning southern blue whiting (Micromesistius australis) fishing by the Argentine fleet in the period 1989-1995 are analized. Catch and effort statistics, fleet operation modalities and spatial and temporary characteristics of fishing activities are included. The basic information to perform this analysis was collected from the fishing statistics provided by the Subsecretaría de Agricultura, Ganadería y Pesca of Argentina and from reports of the Observers Program on board of the commercial fleet. It was in 1989, when the first ship for surimi production entered the fishery, that southern blue whiting catches carried out by the Argentine fleet became important. As of 1989 catches increased in a steady way to stabilize at near 100,000 annual...
