Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ivanovic, M.L.; Brunetti, N.E.
The diet of red squid (Ommastrephes bartramii)during autumn 2001 and2002 in the SW Atlantic region off Argentina and Uruguay (33° S-42° S;46° W-55° W)was composed mainly of fish (55-68. ), followed by squid (32-37. ) and zooplankton (8. only in 2001). Around 60. of the fish eaten was identified as myctophids and corresponded to five genera and seven species, with higher frequency of Hygophum hygomii (24-34. ). The identification of squids consumed reached 20. in 2001 and 80. in 2002 and the only species identified was O. bartramii, which implies percentages of cannibalism of 5.6. and 25.8. each year. For the range analyzed, 141-443 mm of mantle length (ML), the consumption of fish and squid did not show any relation to the size of predator. In 2001 the...

Estudio de la interrelaciones tróficas de dos elasmobranquios del Mar Argentino, en relación con las variaciones espacio-temporales y ambientales. Squalus acanthias (Squalidae) y Raja flavirostris (=Dipturus chilensis) (Rajidae).
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Garcia de la Rosa, S.B.
As a general rule, sharks and rays play an important role in the energy exchanges among higher trophic levels of the marine food chain and some of them, with an important impact as piscivorous predators.  Squalus acanthias (Squalidae) and  Raja flavirostris (=Dipturus chilensis )(Rajidae), are two elasmobranchs with high apparition frequencies in the SW Atlantic, in the coastal and demersal fishing trawls, co-existing and predating on the principal stocks of bony fish there located, especially the Argentine hake (Merluccius hubbsi). Both species could be transformed into alternative fishing resources, even though they are not currently commercially developed as such. The knowledge on their biology, given in great detail, will provide information for a...

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...

El canibalismo como mecanismo regulador denso-dependiente de mortalidad natural en la anchoíta argentina Engraulis anchoita. Su relación con las estrategias reproductivas de la especie.
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Pájaro, M.
Cannibalism is not an abnormal behaviour and it can be observed in a wide number of animals. In Pisces, cannibalism may be the result of endogenous intraspecific factors (nutritional state, size, age, state of development) or exogenous intraspecific factors (food, density, light). Nevertheless, external fertilization and the high fecundity of teleost fish tend to increase egg cannibalism, in particular among filter feeding fishes such as anchovies. In the present work, two important Argentine anchovy Engraulis anchoita stocks were studied. The first is to the north of 41°S, and spawns during spring on the coastal and shelf waters of Buenos Aires Province,Argentina, and Uruguay. The second one inhabits the Patagonian region, from 41°S to 47°S. It spawns...

Striped weakfish (Cynoscion guatucupa)and whitemouth croaker(Micropogonias furnieri)are one of the most important coastal resources of Bahia Blanca Estuary (Buenos Aires Prov., Argentina). The aims of this thesis were: 1, to analyze the population and morphological characteristics of the juveniles stages of the striped weakfish and the whitemouth croaker living in Bahia Blanca Estuary; 2, to describe the dietary habits of the juveniles of these two species; 3, to analyze the ontogenetic and seasonal diet changes in both species, and 4, to study the feeding interrelationships between both species as well as the interrelationships between each species and its prey. In view of the mentioned objectives, diet was evaluated taking into account the following...

Autores: Garcia de la Rosa, S.B.; Sánchez, M.F.
The spiny dogfish, Squalus acanthias is an euribatic, euritermic and cosmopolitan specie. In the Argentine Sea it consumes diversity of preys, characteristic of a generalist and oportunist feeder, butits principal food items are ctenophores, fishes and cephalopods.Diet overlap between sexes was found between 34°-37°S and 101-150 m,where males principally feed on fishes, squid and polichaetes,sharing only ctenophores and hake consumption with the females. Near 62 cm TL there is a shift in the diet, due to an increment of argentine hake Merluccius hubbsi and squid Illex argentinus predation and a diminution in ctenophores Pleurobrachia pileus eating. Feeding shows an increment from north to south, its mode on 42°-43°S.Argentine hake is an important prey...

Aspectos de la conducta alimentaria del mero (Epinephelus morio) del Banco de Campeche
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Giménez, E.; Anderes, B.; Moreno, V.; Burgos, R.
Results of stomach contents analysis of 855 red grouper specimens (Epinephelus morio) caught in Campeche Bank are presented. Individual length composition ranged from 25 to 89 cm fork length (Lf). Fishes (28%), crabs (43%), and shrimps (18%) integrated the main feeding groups in the stomach contents, with no preferential prey-feeding pattern observed. Crabs (33%) are the preferred prey for fish smaller than 55 cm Lf. From this size on fishes (42%) become the most represented items. A significant difference was found in the frequency distributions of preys by regions, with the central region showing the highest abundance. No significant differences in the prey frequency distributions by depth were observed. Feeding activity occurs all around the year, with...

El trabajo expone los resultados del análisis de contenido estomacal de 855 individuos de mero (Epinephelus morio) capturados en el Banco de Campeche, con tallas entre 25 y 89 cm de longitud furcal (Lf). Los peces (28%), cangrejos (43%) y camarones (18%) predominan en el contenido gástrico. En tallas menores de 55 cm la frecuencia relativa de cangrejos es mayor (33%) y a partir de dicho tamaño los peces (42%) pasan a ser los más representados. Se detectó diferencia significativa en la distribución de frecuencias de las presas entre regiones, siendo la región central la de mayor abundancia. No se aprecian diferencias en la distribución de frecuencias de las presas por profundidad. La actividad alimentaria se manifiesta durante todo el año, con más...
