Abundancia relativa y distribución de tallas de corvina rubia Micropogonias furnieri y pescadilla de red Cynoscion striatus en la Zona Comun de Pesca Argentino-Uruguaya y en el Rincón. Noviembre, 1994. OceanDocs
Carozza, C.R.; Cotrina, C.P..
The study aims to discriminate juvenile and adult concentration areas of white croacker Micropogonias furnieri and striped weakfish Cynoscion striatus in two different areas: Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina). The length structure and the relative abundance of these two species were analyzed with data from a research cruise carried out by R/V Dr.E.L.Holmberg during November 1994. Data of relative abundance in t/nm2 were considered to define distribution and concentration areas. 49 samples of white croaker and 41 striped weakfish from AUCFZ a, inside the area of Río de la Plata and in front of Montevideo coast, at depths lesser than 8 meters, while the adults were located in the northern coast of...

Análisis de la estratificación empleada en campañas de evaluación de recursos demersales costeros en la Zona Común de Pesca Argentino-Uruguaya y en El Rincón, 1994 OceanDocs
Perrotta, R.G.; Lasta, C.A.; Aubone, A..
The data belong to the demersal fishery research cruise H-13/94. Stratification used for research surveys from the catches values was tested, both for the northern area, Argentine-Uruguayan Common Fishing Zone (AUCFZ) located between 34° and 39°S, and the southern area situated between 38°30' and 41°30'S (El Rincón, Buenos Aires Prov., Argentina). The variables considered were: croaker and striped weak fish densities and depth. Discriminant factor analysis indicates the formation of two and six strata for the southern and northern areas respectively. The adequate confidential limits of the estimated biomass for each strata obtained for different species, indicate that the criteria for stratification is satisfactory. The number of catches by strata was...

Análisis de la utilización de la captura por unidad de esfuerzo de pescadilla de red (Cynoscion guatucupa) como índice de abundancia anual. Período 1992-2004 OceanDocs
Perrotta, R.G.; Ruarte, C.O..
The stripped weakfish (Cynoscion guatucupa) caught in Brazil, Uruguay and Argentina (SW Atlantic) has a wide latitudinal distribution (22° S-43° S). In Argentina there are two main fishing areas, the Argentine-Uruguayan Common Fishing Zone and 'El Rincón', southern zone of the Buenos Aires littoral. The importance of the species makes it necessary to define an annual abundance index that would allow to diagnose the state of the stock. The model adjusted to calculate the index is the General Linear Model. The factors used were Year, Quarter, Length, Stratum (4 categories) and sub-areas (5 categories), all statistically significant. The problem generated by the presence in the model of first order interactions that include the Year factor is discussed. The...

Característica y dinámica de la explotación de corvina rubia (Micropogonias furnieri) durante la zafra invernal, años 1995 a 1997. OceanDocs
Lasta, C.A.; Carozza, C.R.; Suquelle, P.; Bremec, C.; Errazti, E.; Perrotta, R.G.; Cotrina, C.P.; Bertelo, C.; Boccanfuso, J..
Whitemouth croaker Micropogonias furnieri fishery during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet...

Caracteristicas de la pesca artesanal en el Partido de la Costa (Cabo San Antonio) y perfil socioeconomico de la actividad. OceanDocs
Lagos, A.N..
There is a lack of scientific information about the artisanal fishery in the de la Costa County (Buenos Aires province, Argentina). Moreover, this artisanal sector does not have fishing statistics because local fishermen are not obliged to hand in fishing reports, where even basic data on catch and fleet effort should be included. The main objective was the analysis of the artisanal fishery in the de la Costa County from the biological, economic and social point of view. One 132 sample stations were analyzed between 56 degree -57 degree W and 36 degree -37 degree S from 1992 to 1999. Moreover, information on the artisanal fleet, environmental conditions and the arrival of tourists to the de la Costa County was also analyzed. Fishing yield (FY) per boat was...

Ruarte, C.O.; Perrotta, R.G..
The stripped weakfish (Cynoscion guatucupa) has a wide latitudinal distribution (22° S-43° S) and it is object of fishery in Brazil, Uruguay and Argentina (SW Atlantic). In this last country, it is mainly captured in the coastal region of Buenos Aires Province by means of a fleet, which has between 20 m and 30 m length. In Argentina, the average landings in the last 5 years were 9,900 t. It is the second commercial species among the coastal groups. There are two main fishery areas of this species: the Argentinean-Uruguayan Common Fishing Zone (AUCFZ) and the El Rincón area, in the South of bonaerense littoral. Due to the importance of this species, it is necessary to define an index of annual abundance to allow a suitable diagnosis of the fishery...

This chapter includes an economic analysis of the small scale fleet of the Mar del Plata harbour, Buenos Aires Province, Argentina. The original study was carried out at the request of the Skippers Fisheries Society to find out the relative efficacy and efficiency of homogeneous groups of associated vessels. Based on the information available, to tune the observed data, assess the relative efficacy and estimate the relative economic efficiency of the fleet, an ad hoc model was designed. Length, gross registered tonnage, engine power and number of crew members were considered and analyzed as structural variables for 1995, 1996 and 1997. No changes in variables for the period were observed so, the efficacy and efficiency analysis was carried out for the year...

Volpedo, A..
Otoliths (sagitta, asteriscus and lapillus)are complex structures composed of calcium carbonate, other minerals, and a protein matrix. Otoliths are located in the internal ear of the teleost fishes. The shape and structure of otoliths are specific for each species. For this reason, otoliths are used to identify species in biological and ecological studies.Sciaenids conform a group of fishes of commercial importance, so the handling of this resource is a high-priority topic for the local and national economies of countries that exploit these species. The purpose of this work is to study different aspects of the sagittae of marine sciaenids from Argentina and Peru. The morphology, morphometry and chemical composition has been analyzed in relation to the...

Estudio preliminar de la edad, el crecimiento, área de distribución y pesca de la corvina negra, Pogonias cromis, en el litoral de la provincia de Buenos Aires. OceanDocs
Urteaga, J.R.; Perrotta, R.G..
Argentine black drum distributes mainly in shallow waters associated to estuarine areas, particularly to Samborombon Bay where it may be detected throughout the year. Nevertheless, it can also be spotted more southwards (40°S) and at deeper waters. During summer, catches of the species in Samborombon Bay are practically negligible, probably due to movements towards shallow waters out of reach of the inshore commercial fleet. Landings increase in autumn and show peak values in winter, coinciding with the fishing season of whitemouth croaker, Micropogonias furnieri, whose geographical distribution within the bay overlaps that of black drum. As of 1995, landings of black drum showed increasing trends both in Argentina and Uruguay. These increments coincide...

Elias, I.; Pereiro, R..
Artisanal fishing activities bivalve extraction through diving, hand-collection of octopuses and beach seine fishing are currently the only ways to exploit the coastal resources inhabiting the Argentine Northern Patagonian gulfs 42°43°S from the SW Atlantic. These are time-restricted activities. Diving and hand-collection are limited by management and sanitary policies while resource variability and commercial demand limit beach fishing. The objective of this work was to test a productive alternative, i.e., the use of longlines to increase and diversify catches in order to improve commercialization, contribute to a rational management and alleviate the pressure put on the resources exploited at present. Results obtained indicate that profitability of...

Whitemouth croaker (Micropogonias furnieri)has a broad distribution along the Atlantic coast of the Americas, from Mexico to the south of the Province of Buenos Aires, Argentina. At the southern end of distribution, Argentina and Uruguay catch the species with different commercial fleet types bay or creek, coastal and off-shore and modalities of bottom trawling with doors and paired trawling. Maximum catches of both countries, that reached 60,000 t, were registered between 1995 and 1997. After that period a remarkable decrease was observed, specially in Argentina where catches remained at around 6,000 t over a total of 30,000 t for both countries. The commercial fleet was divided in three categories and the total area of study in three subareas: El Salado,...

Brazilian flathead (Percophis brasiliensis), of wide latitudinal distribution (23° S-47° S), is caught in Argentina in two coastal areas north and south of the Province of Buenos Aires delimited by the 39° S latitude. The species shows the highest abundance and catch yield percentages ( 5. ) of all coastal fish groups. The importance of the species makes it necessary to analyze mean lengths and define an annual abundance index that would allow to diagnose the state of the stock. To calculate the index the General Linear Model was adjusted. The factors used were Year, Quarter and 4 sub-areas, all statistically significant. The problem generated by the presence in the model of first order interactions that include the Year factor is discussed. It is...
