Creación de un banco de progenitores de Róbalo Centropomus undecimalis, Bloch. Evaluación de alimentos artificiales

Blanco, W.; Fraga, I.; Tizol, R.; Artiles, M.A..

Two experiments were accomplished with wild P. argus lobster postlarvae collected from the sea in pelagic collectors. In the first one, the effect of two foods (live and frozen Artemia) was tested on 0.17 g lobsters in a 40 days feeding trial. Significant differences were found (p<0.05) between the final weight, survival, weight increment, molting rate and NBI, the highest values were for live Artemia with the highest survival (93%). Mortalities using frozen Artemia were almost entirely attributable to cannibalism of postmoult lobsters. In the second experiment, the average initial weight was 0.26 g during 120 days and three densities (50, 70, 90 n/m2) were tested, the feeding regimes were live Artemia and pellet during 60 days the rest of time with...

Reyes, R.; Ramos, D.; Fraga, I.; Galindo, J.; Ortega, N..

Feeding is one of the most critical aspects in fish broodstock establishment. The goal of this work is to evaluate the behavior of Centropomus undecimalis juvenile with two-compounded diet. Snook with initial average weight of 371.5 ± 77.8 g were kept during 10 month in 6 fibber glass tanks of 5 m3 capacity with 15 individual each. Two semimoist diet including fishmeal and fresh food were tested. The diet supplied were composed of minced meat fish machuelo (Ophistonema oglinum) and patao (Gerres spp) and small shrimp (so-called trilla) in the first five month and shrimp head and squid the rest of the time. At the beginning of this experience, growing was very slow with 15.33 g/month and food conversion of 6.5 mean while average weight of 26.6 g/month and...

Essais d'utilisation de "nourrisseur à la demande" pour l'alimentation de Chrysichthys nigrodigitatus en cage-enclos.

Galindo, J.; Fraga, I.; Artiles, M.A.; de Arazoza, M.; Alvarez, J.S.; Pelegrín, E..

To assess the effect of protein levels in diet on growth of pink shrimp juveniles (Farfantepenaeus notialis), two completely randomly experimental designs were carried out, one at laboratory scale during 8 weeks and the second one in fertilized earthen ponds during 20 weeks. Samples of pink shrimps obtained after spawning in the laboratory, were used. Isocaloric practical diets containing 35, 40 and 45% were used in the first experiment and 40 and 45% protein in the second one. In both trials, shrimps fed with 45% protein diet reached the highest growths. The nutritional factors assessed were always better in that organisms fed with the diet of higher protein content. The histological analysis of the hepatopancreas in shrimp feds with diets containing...

Galindo, J.; Fraga, I.; de Arazoza, M.; Fajer, E.; González, R.; Forrellat, A..

The effect of diets with different protein levels on the growth of pink shrimp juveniles Penaeus notialis under laboratory conditions was studied. Animals with initial average weight of 0.4 g were fed during 56 days using four isocaloric (350 kcal/100 g) and isolipidic (8.7 %) balanced diets, containing 30, 35, 40 and 45 % of protein. Shrimp fed with the diet containing 45 % of protein reached the highest growth and the best values for nutritional indixes under evaluation. The protein efficiency tended to increase when the protein level in food also increased. A significant relationship was verified between shrimp weight and in vitro digestibility of diets. No relationship was detected between enzimatic activity of trypsin and general proteases for the...

Impact of starvation and of feeding algal and artificial diets on the lipid content and composition of juvenile oysters (Crassostrea gigas) and clams (Tapes philippinarum)

Jaime Ceballos, B.; Villareal, H.; Garcia, T.; Pérez Jar, L.; Alfonso, E..

To evaluate the effect of Spirulina platensis inclusion in microdiets for white shrimp Litopenaeus schmitti larvae, a completely randomized experimental design was developed with 4 treatments and three replicates. Diets with 3 inclusion levels (0, 2.5 and 5%) were prepared. A control was fed Artemia nauplii. Larvae were fed for 120 hours from mysis I to postlavae 1 every 4 h, and water quality parameters were measured daily. At the end of the experiment survival was determined, and the development index of the larvae was calculated. The chemical score of the diet was also determined, using the L. schmitti postlarvae amino-acid pattern as reference. Triptophan and hystidine were the first and second limiting amino acids in the diets. Survival was around 80%...

Rearing bivalve molluscs in commercial hatchery and nursery systems has so far relied on the production of live algae, which is costly and often unpredictable. Therefore the development of satisfactory artificial diet would greatly reduce the operating costs of bivalve operations. The development of techniques to improve the nutritional composition and digestibility of yeasts resulted in a product with great potential as a substitute for unicellular algae. Previous work on the Manila clam Tapes semidecussata showed that replacing 80% of the algae by these manipulated yeasts resulted in growth rates of 64 to 93% in comparison with the growth rate obtained for the algal control. In the present study a standard culture test for evaluating...

The effect of linoleic acid (18:2n-6) and n-3 highly unsaturated fatty acids (HUFA) on the reproductive performance and offspring quality of the freshwater prawn Macrobrachium rosenbergii was evaluated in a 180-day trial. Three isonitrogenous and isolipidic diets containing different levels of fatty acids, high 18:2n-6 and n-3 HUFA concentrations, high 18:2n-6 and low n-3 HUFA, and low 18:2n-6 and n-3 HUFA, were fed ad libitum to three groups of six females. Fecundity was improved by the addition of higher amounts of 18:2n-6 (from 3 to 13 mg g-1 DW). As a consequence of higher fecundity, smaller eggs were obtained most likely because the number of oocytes competing for a limited amount of yolk was higher. The...
