- ItemAlgunas características de la estructura y del comportamiento migratorio de los cardúmenes de caballa (Scomber japonicus marplatensis) en la plataforma bonaerense (Mar Argentino) : período 1965-1984(Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1987) Cousseau, M.B.; Angelescu, Víctor; Perrotta, R.G.Three periods were distinguished during the analyzed years: the first one (1965-1975) may be defined as "normal fishing seasons" occurring from October to March, with catches between 8,000 and 14,000 tons.
- ItemEcología trófica de la anchoíta (Engraulidae, Engraulis anchoita) del Mar Argentino. Parte III. Requerimiento trófico individual en relación con el crecimiento, ciclo sexual y las migraciones estacionales(Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1986) Angelescu, Víctor; Anganuzzi, AlejandroThe paper was developed in order to arrange the data gathered on this subject and to generate new hypotheses in connection with the trophic strategy of the northern stock of anchovy in the area between latitudes 35°-42°S. Such estimates were finally compared with the values of the gravimetric determinations of stomach contents- as converted to caloric values - of individuals grouped by total-length amd age classes, ecological areas, and seasons of the year. The set of results as obtained conforms the initial basis for developing Part IV of the Trophic Ecology of the Argentine anchovy as related to food consumption estimates, by stock biomass and annual classes, with back-calculations to age class 0, and for applying "regional patterns" that result from the "consumer-food" relationship.
- ItemEcología trófica de la caballa del Mar Argentino (Scombridae, Scomber japonicus marplatensis). Parte I. Alimentación y crecimiento(Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1979) Angelescu, VíctorThe present study describes the morphology of the digestive system, the feeding and feeding behaviour, and the trophic relationships of the mackerel in the coastal waters regions, pelagic zone, along the Province of Buenos Aires. At the same time, this study is completed with a bioestatistical analysis on growth rhythm of body length and body weight of secondary juveniles, pre-adults and adults. All the biological information and statistical data correspond, only to the period november-march and the summer trophic habitat area.
