Appendicularians: an important food supply for the Argentine anchovy Engraulis anchoita in coastal waters

Journal of Applied Ichthyology, 2005
Summary The stomach contents of 532 adult specimens of the Argentine anchovy, Engraulis anchoita, caught in coastal waters of the Argentine Sea from 1994 to 1996, were analyzed. Larger amounts of food were found in the stomachs of anchovies collected in the northern surveys (35–40°S), with the highest values attained in 1994.

Fish length prediction from acoustic descriptors of Anchovy (Engraulis anchoita) schools

2015 IEEE/OES Acoustics in Underwater Geosciences Symposium (RIO Acoustics), 2015
In a fishery assessment context, Artificial Neural Networks (ANNs), among other techniques, have been intensively tested for the identification of fish species and pursuing the automatic classification of the schools, based on descriptors extracted from digital echosounder recordings.

Development of the visual system of anchovy larvae, Engraulis anchoita: A microanatomical description

Journal of Morphology, 2020
AbstractDuring the early ontogeny of fish larvae, the accurate development of the visual system plays a key role, because it is involved in locating food, orientation, selection of favorable habitat, and evasion of predators. The structure of the eye of the fish is typical of vertebrates, with some modifications related to the aquatic environment.

On-board handling and preservation of anchovy (Engraulis anchoita) catches

International Journal of Refrigeration, 1990
Abstract The anchovy of the Argentine Sea is an under-exploited resource due to the effect of economic and technological factors. Any proposal to increase the exploitation of this resource must consider on-board handling and preservation of the catch as critical points because the characteristics of the fish (high lipid contents, muscle fragility and

Chymotrypsin and general proteolytic activities in muscle of Engraulis encrasicolus and Engraulis anchoita during the ripening process

European Food Research and Technology, 2000
During fish ripening, biochemical changes occur that give rise to the organoleptic properties characteristic of the product. Enzymes play a key role in this ripening process, although it is not known exactly which enzymes are involved. We investigated the effects of the gutting method (nobbing only, or nobbing and butterflying) and addition of ...

Anchovy stocks (Engraulis anchoita) and larval growth in the SW Atlantic

Fisheries Research, 2003
Abstract Growth rates of anchovy larvae were estimated from samples collected in the Brazilian Southeastern Bight (BSEB) in June/July and November/December, 1995. Horizontal distribution and abundance of the larvae were determined. The rate of ring formation on the otolith was related to the marginal increments and time of day.

Shelf Life of Brine Refrigerated Anchovies (Engraulis anchoita) for Canning

Journal of Food Science, 1984
The possibility of keeping anchovies in brine at 0°C was studied. The storage life of anchovies under these conditions was about 85 hr. The concentration of brine seems to have little effect on the quality loss at the concentrations used in this study. An acceptability level for the raw material basedon sensory attributes cannot be established with any
