Evaluación de diferentes niveles de inclusión de ensilado químico de pescado en dietas para Clarias gariepinus(Burchell, 1822)
Provedor de dados: 20
Autores: Llanes Iglesias, J.; Toledo Pérez, J.; Lazo de la Vega y Valdez, J.
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 &gt; 0,05) between experiment diets, representing between $188,00 and 302, 00 USD/t saving at fingerling.

Consideraciones sobre la alimentación de la caballa con especial enfasis en la depredación de huevos y larvas de peces
Provedor de dados: 20
Autores: Pájaro, M.
Adult and juvenile fish inter and intraspecific predation may be an important source on these first development stages. In this work, adult and juvenile mackerel samples from two areas of Buenos Aires province, one south of Cape San Antonio and the other near Mar del Plata city were analyzed. An important anchovy postlarvae ingestion in both regions considered was observed. A high number of mackerel eggs in the stomach contents from adults was identified. This evidence of cannibalistic behaviour in the argentine mackerel is the first of its kind made in this species and allows to suggest that embryo mortality due to cannibalism might constitute and important percentage of the total embryonic mortality.

Ecología trófica de peces demersales en el Golfo San Jorge
Provedor de dados: 20
Autores: Sánchez, M.F.; Prenski, L.B.
This work is a first approach in the study of the trophic ecology from a multispecific fishery in San Jorge Gulf (45°-47°S), Argentina. Stomach contents from 28 demersal fish species were analyzed. Taxonomic and trophic spectrum were obtained. Using weight percentage of each prey, trophic spectrum variations for size classes were analized for each of the 12 considered "dominant" species. Overlaping in the diet among these predators was estimate using cluster analysis. There was an interespecific diet overlap between juveniles belonging to demersal-benthic fish species, because all of them prey upon Stomatopoda and Munida. Adults from those species and hake prefered young and adult hake as preys, while Macruronus magellanicus and juvelines Merluccius hubbsi...

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&lt;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&gt;0.05) when GICABU was included up to 10 % in juvenile diet. Total replacement of sunflower oil by...

Caracterización de playas de anidación y zonas de alimentación de tortugas marinas en el Archipiélago de San Bernardo, Caribe colombiano
Provedor de dados: 20
Autores: Rincón-Díaz, M.P.; Rodríguez-Zárate, C.J.
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...

Provedor de dados: 20
Autores: Sánchez, R.P.; de Ciechomski, J.D.; Lasta, C.A.; Guerrero, R.A.
Lagrangian changes in distribution and survival within an anchovy egg and larvae patch were studied by means of multiple opening/closing sampling following a free drifting buoy. The buoy was equipped with a radar reflector and flashing light, and it was connected to a current cross drogue floating at 15 m depth, which corresponded to the main egg and larvae concentration within the patch. The drifter was launched on the Buenos Aires continental shelf, off Necochea during the spring spawning peak of 1983. Three discrete depths (within, below and above the thermocline)were repeatedly sampled close to the drogue with a Motoda sampler. Egg and larval abundances in the vicinity of the drogue were monitored at 3/4 hour intervals for a period of three days. Each...

Autores: Aristizabal, E.O.; Suárez, J.
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...

The results of the final on-growing (500 g to 1 kg)of flounder Paralichthys orbignyanus under closed recirculated water systems and controlled conditions are presented. 22.5 percent of fish reached 1 kg alter 2.1 months of starting the on-growing trial. Sex ratio was 20.6 percent females and 79.4 percent males. Average length for females and males was 38.53 ± 4.58 cm TL and 32.52 ± 5.25 cm TL, respectively. Average body weight for females and males was 710.58 ± 262.95 g and 427.59 ± 203.01 g, respectively. Statistically significant differences were found for average length for sex (p0.01)and for average body weight for sex (0.01 0.05). Flesh yield was 43.1percent fillets without skin and 57percent fillets with skin. Flesh of cultivated flounder had a...

Efecto de la salinidad y la temperatura sobre el ciclo de vida de cangrejos estuariales (Decapoda, Grapsidae).
Provedor de dados: 20
Autores: Bas, C.
El ciclo de vida de los cangrejos verdaderos (Crustacea, Brachyura) incluye en la mayoria de los casos cuatro etapas. Una etapa embrionaria, en la cual los huevos en desarrollo protegidos por una membrana de varias capas, se mantienen adheridos a los ple6podas de la hembra, expuestos a las mismas condiciones ambientales que el adulto . Posteriormente una etapa larval planct6nica y finalmente una fase juvenil y una adulta, ambas bent6nicas en igual o diferente ambiente . Muy frecuentemente [as historias de vida de los organismos son referidas como rigidamente definidas para cada especie, sin embargo existen numerosos ejemplos en invertebrados donde las caracteristicas del desarrollo y la reproducci6n de una especie son ampliamente influenciadas y...

Estudio comparado de la alimentación entre algunos predadores de alto nivel trófico de la comunidad marina del norte y centro de patagonia
Provedor de dados: 20
Autores: Koen Alonso, M.
The comparative analysis of the food habits between top predator allows the evaluation of how these species use the trophic resources. They also make possible the study of potentially competitive relationships and the role of these predators in the regulation and structure of the community. The marine community of northern and central Patagonia is structured on the tri-trophic system composed by the Argentine anchovy (Engraulis anchoita), the Argentine shortfin squid (Illex argentinus), and Argentine hake (Merluccius hubbsi). Several marine mammals and elasmobranchs use these species as food resources. For this reason, the objective of this work was to analyze comparatively the diet of the South American sea lion (Otaria flavescens), the dusky dolphin...

Desarrollo de un banco de reproductores de Róbalo (Centropomus undecimalis, Bloch 1792): I. Manejo del alimento
Provedor de dados: 20
Autores: Fraga, I.; Reyes, R.; Ortega, N.; Regueira, E.; Font, R.; Bravo, A.
In order to establish the management methods in snook Centropomus undecimalis (Bloch, 1792) broodstock (initial average weight 960 g), during 18 month three phases were developed. Fishes were marked, measured, weighed and distributed in 5 m3 fiber glass tanks (stock density 1.3 kg/m3). In the first phase (3 month), different feeding schedules were applied: 1. feeding in alternate days; 2. feeding every day excluding weekends; 3. feeding twice a day. Before maturation phase and during three month, enriched semi humid food was supplied. Finally, during 12 month, artificial feed was supplied. The appetite dynamics in fishes was influenced by the feeding schedule applied. When food was offered in alternate days, higher consumption was observed. Females showed...

Conducta alimentaria del camarón Litopenaeus vannamei durante la época  invernal en estanques de tierra
Provedor de dados: 20
Autores: Alvarez, J.S.; Sorí, M.A.; Pelegrin, E.; Galindo, J.
Esta investigación se realizó en la camaronera CULTIZAZA, Sancti Spiritus, ante la  necesidad de continuar profundizando sobre el comportamiento alimentario del camarón  blanco del Pacífico  Litopenaeus vannamei, como una vía más para mejorar las  condiciones financieras y salud de la camaronicultura cubana. Los resultados indicaron  que en época de invierno se requiere de mayor vigilancia en el manejo del alimento en los  estanques de cultivo respecto al verano, para evitar suministros innecesarios de alimento  que incrementarían la contaminación en los estanques, las situaciones de estrés y  aparición de enfermedades que conspiran finalmente con la rentabilidad de la granja.

The high cost of using live microalgae and the variations in nutritional value during larval culture constitute a problem for any operation relying on the massive culture of unicellular microalgae. The price of Artemia cysts in the international market and the increasing demand in Cuba, due to the development of the shrimp culture industry, has made the search of feeding alternatives that can of satisfactory diminish the live food consumption in shrimp larviculture, essential. Spirulina platensis meal (SPM), produced commercially in Cuba, has optimal nutritional characteristics to be used as a food ingredient in any aquatic animal culture.  For that reason in this thesis we set out to improve the efficiency in the production of Litopenaeus schmitti shrimp...
