| The objective of this study was to evaluate five half-moist diets with graded levels of chemical fish silage (40, 50, 60, 70 and 80 %) prepared with 2 % sulfuric acid 98 % (weigth/volumen), as a unique animal protein source. They were compared with a commercial food (20 % of fish meal), Clarias gariepinus feeding during 60 days. The experimental design was completely randomized and the statistical analysis of the results was done through analysis of variance and the results were compared through the Duncan test at 5 %. The results showed that indicators such as: growth, feed utilization and survival rate did not differ significantly (p > 0,05) between experiment diets, representing between $188,00 and 302, 00 USD/t saving at fingerling. |

| Results of the inclusion of GICABU and torula yeast in the diet for the Caribbean white shrimp (Litopenaeus schmitti) juveniles and cachaza oil in postlarvae diet are presented. Three completely randomised experimental designs were carried out to evaluate practical and semipurified diets, in juveniles and postlarvae respectively, with different by-products inclusion levels. Food was accepted and consumed in all the experiments. Shrimps reached a significantly higher growth (P<0.05) when torula yeast was included at 15, 20 and 25 % in diet, thus demonstrating the feasibility of the partial fish meal substitution. No significant differences were found (P>0.05) when GICABU was included up to 10 % in juvenile diet. Total replacement of sunflower oil by... |

| The San Bernardo Archipelago, in the Colombian Caribbean zone, is well recognized for being a sporadic nesting and feeding area for the green, hawksbill and loggerhead turtles. Due to the fact that the San Bernardo Archipelago has outstanding coral areas, marine grasses and sandy beaches and their environmental offers for the marine turtles have not been described yet, it was opportune to carry out this study between July and October of 2002. Thus, this research tends to fill this gap by describing the nesting beaches and feeding areas according to their geomorphologic and biotic aspects and, for the later areas, some oceanographic aspects too. Seven potential nesting beaches and 20 stations on feeding areas were evaluated to identify natural and... |

| Considering the need to help the Cuban shrimp culture industry remain profitable, and the impact that feeding has on production costs, a research series was designed to evaluate new formulations that improve white shrimp Litopenaeus schmitti growth and reduce feeding costs. Five completely randomized experiments with 3 replicates per treatment were conducted. Juveniles (0.2-0.5 g) from the experimental farm were used. Trials were conducted at the Centro de Obtención y Cría de Larvas de Santa Cruz del Sur, Camaguey, and the Complejo Camaronero de Tunas de Zaza, Sancti Spiritus. In the first trial, 40-l plastic experimental units with 10 shrimp/unit were used to test the response of L. schmitti to the partial and total substitution (46, 59, 75, 88 y 100%) of... |

| Zygochlamys patagonica is distributed in the Atlantic Ocean from 35 degree S to Tierra del Fuego (Argentina), and in the Pacific Ocean, up to 42 degree S, between 40 and 200 m depth. There are 9 beds in the Argentinian Sea. Scallops are suspensivore organisms, feeding on detritus and phytoplankton. The aims of this thesis are to make a quali-quantitative study of the diet of the Patagonian scallop, to detect seasonal changes in diet and to link these results with oceanographic conditions and with the growth pattern. Gut contents of 180 scallops were analyzed from samples (n=30) taken in June, August, October and November 1996, and February and March 1997. This procedure was tested statistically. Twelve species of diatoms and resting stages, five species of... |

| The red porgy (Pagrus pagrus)is an important commercial and recreational species with very good prospect for aquaculture. Because significant mortalities, the mass production of this species is limited. This paper describes three weaning strategies to investigate their effects on the survival and growth of red porgy larvae reared in laboratory: A)traditional three-step weaning (rotifers - Artemia - diet)(control); B)one-step early weaning by co-feeding (rotifers - Artemia + diet), and C)one-step direct early weaning (rotifers - diet). Sigificative differences were recorded among treatments (P0.05). Best survival rate (45.6 ± 7.6 percent)and growth (7.4 ± 0.5 mm)were found in treatment B. Results indicate that co-feeding red porgy larvae with inert and live... |

| Feeding of Argentine hake during winter 1994, between 50 and 370 m of depth, in the studied area (34°50'-47°S), is based on the consumption of zooplanktonic crustaceans, fishes and cephalopods. Maximum feeding incidence is found at 36°-40°S (51. ), in sea layer of 80-130 m deep (62. ) and between 8:00-10:00 hours (36,6. ). Cluster analysis shows five spatial groups, with similar length distributions and characteristic principal prey items combination. The males of all sizes show a trend to feed on euphausids and hiperiids amphipods. The females eat more quantities of hake, short fin squid and other fishes. There is a change in diet related with predator size, from 47 cm TL onwards for males, and from 53 cm TL for females. This change consists in a decrease... |

| Four species of the family Octopodidae were reported to occur along the Argentine coast Octopus tehuelchus, Eledone massyae, Enteroctopus megalocyathus and Robsonella fontaniana. The first two are distributed from Brazil to south of Rawson and San Jorge Gulf, respectively, in warm-temperate waters. E.megalocyathus and R.fontaniana are of Subantarctic origin, the first ranging from San Matias Gulf to Magellan Strait, the Beagle Channel and Malvinas Islands; R.fontaniana is distributed from San Matias Gulf southwards, with records in North Patagonian and San Jorge Gulfs, Chile and Peru. A synopsis of information about taxonomical status, patterns of geographic distribution and biological aspects of these four coastal octopodids is given. |
