Detección de un área de cría de la merluza de cola (Macruronus magellanicus)en el Mar Argentino.
Provedor de dados: 20
Autores: Machinandiarena, L.; Ehrlich, M.D.
This is the first report of a longtail hake (Macruronus magellanicus)nursery ground. The results of more than ten research cruises conducted since 1990 in the southern patagonian shelf are presented in this study. The nursery ground (52°S to 55°30'S)was detected by the presence of larvae between 5.60 to 12.80 mm of standard length in November and December in that area, with depth ranging from 90 to 160 m.

Autores: Sabatini, M.
Fish recruitment seems to be influenced by environmental variability;the plankton would act as a link between both processes. While environmental variability can be explained in terms of physical forcing, recruitment variability is partly determined by the survival of early larvae. In this review, the available information on hydrography and plankton in relation to reproduction and feeding of hake (Merluccius hubbsi)and anchovy (Engraulis anchoita)in the Patagonian Argentine Sea, SW Atlantic spawning ground was summarized and integrated. The objective was to assess what is actually known about the environmental and planktonic features of the region that may have an effect on the recruitment of both species. In the Patagonian spawning ground, detection, in...

Alimentación del pez limón, Seriola lalandi (Valenciennes, 1833 in Cuvier y Valenciennes, 1833) en aguas bonaerenses
Provedor de dados: 20
Autores: Vergani, M.
The yellowtail kingfish, Seriola lalandi, Carangidae (Valenciennes, in Cuvier y Valenciennes, 1833) is a pelagic, schooling fish, with gregarious behaviour. It is a circumglobal species from tropical and temperate waters. Adult S. lalandi migrate to Argentine waters (SW Atlantic) during summer months (January-April). They have been reported from Argentine waters in depths of 20-36 m between 36°S and 38° and, as reported elsewhere in the world, are often associated with rocky reefs. Samples of S. lalandi were caught using trolling lines during daytime around rocky reefs at 35° 52'-35° 58'S and 54° 45'-54° 48'W, on February 15-22, 2002. Sixty-six adult S. lalandi were analyzed, with specimens measured (LT) and weighted (WT). The length-weight relationship...

Mapeo sinóptico del macrobentos asociados a la dieta en fondos de alimentación de la corvina rubia Micropogonias furnieri en el área de El Rincón, Noviembre, 1994
Provedor de dados: 20
Autores: Bremec, C.; Lasta, M.L.
The faunistic characteristics in feeding grounds of Micropogonias furnieri, considering many relationships with the diet of the species in the Argentine-Uruguayan Common Fishing Zone, are studied. Benthos was collected in 33 sampling stations during the reseach cruise H-13/94, between 9-44 meters depth in the area El Rincón (Buenos Aires Prov., Argentina), with hard bottom and Picard dredges. Cluster analysis (Q mode, Sorensen index) was applied to these data and to the invertebrate by-catch obtained in 58 demersal hauls. Frequency size distribution of mussels in its distribution area is also presented. Stomach contents of 177 specimens of white croaker were studied from the percentage of ocurrence frequence of every alimentary item. Present results and...

Análisis espacio-temporal del estado nutricional de larvas de anchoíta Engraulis anchoita. Relación con las características hidrográficas y la disponibilidad de alimento
Provedor de dados: 20
Autores: Díaz, M.V.
Nutritional condition studies allow the assessment of physiological state of each larva and thus, the establishment of favourable nursery areas which provide better survival and growth. In the present work, morphometrical, histological and biochemical techniques were employed to assess nutritional condition of anchovy, Engraulis anchoita, larvae captured in the Argentine Sea. Its results were complemented with oceanographic data and information about zooplankton abundances, both prey and predators of anchovy larvae. Anchovy larvae abundance and distribution would be mainly determined by physico-chemical variables. Even though no significant differences were found in larval nutritional condition among the studied areas, larval condition was slightly better...

Índice de abundancia del grupo merluza de edad 2 en el área de cría patagónica. Período 1995-1998
Provedor de dados: 20
Autores: Castrucci, R.; Aubone, A.; Pérez, M.; Renzi, M.A.
An abundance index of hake Merluccius hubbsi individuals age 2 was estimated in the nursery area south of 41°S Argentine Sea, SW Atlantic. The analysis comprised the 1995-1998 period and was made with data derived from research surveys programmed to that end. A mean value estimator of CPUE catch in number of individuals per trawl hour based on delta distribution was used. The spatial distribution of CPUE of age groups 1 and 2 in the area surveyed, total length distribution per survey and the corresponding age composition are presented. The declining trend of abundance index of hake age 2 observed during the four year period amounted to 52.9.

Variaciones interanuales (1995-2000) de la temperatura y la salinidad registradas en los meses de enero en el golfo San Jorge y aguas adyacentes (43°S-47°S).

Temperature and salinity interannual variations are analyzed south ofthe hake (Merluccius hubbsi)spawning grounds area, in the San Jorge Gulf and adjacent waters Argentine Sea, SW Atlantic. The study period comprises the months of January 1995-2000. Results of cruises carried out on board of INIDEP research vessels to assess hake juveniles were studied. Statistically significant increase of temperature from 1997 was observed. Change trends over a period of 20 years at a global climate scale are discussed. Mean salinity did not show variations except for 2000 when it was slightly higher probably due to the scarce influence of the Patagonian Current in the area. Temperature and salinity fields showed a horizontal gradient south of the Gulf (thermohaline...

Distribución de huevos, larvas y prerreclutas de merluza (Merluccius hubbsi) en la Zona Común de Pesca Argentino-Uruguaya. Período 1999-2001
Provedor de dados: 20
Autores: Machinandiarena, L.; Brown, D.R.; Ehrlich, M.D.; Pájaro, M.; Dorado, J.; Teso, V.
Distribution and abundance of eggs, larvae and prerecruit stages of Merluccius hubbsi were evaluated to examine spawning, nursery and settlement areas in the Argentine-Uruguayan Common Fishing Zone during the 1999-2001 period. Larvae and prerecruit stages were more abundant at stations from 50 m to 100 m depth. The nursery area would extend from the 50 m isobath south of 37° S to the 200 m isobath northward where the shelf becomes narrower. In the whole sampling area small size prerecruits were caught; therefore, the whole zone should be considered as a potential settlement area.
