The possible benefits of feeding a formulated diet, together with Artemia , to first-feeding turbot larvae were investigated. Five dietary regimes were used: control ( Artemia only), cofeeding with a diet rich in phospholipid (PL) from bovine brain, cofeeding with a diet rich in free fatty acids (FFA) from the same source, cofeeding with a commercial diet (Lansy A2), and a formulated feed only (PL-rich diet). All treatments with artificial diets and the control treatment that received Artemia exclusively gave a similar survival rate of the fish at day 29. Cofeeding with artificial diets resulted in a lower growth rate than the control treatment. Cofeeding the larvae with PL-rich or FFA-rich diets did...

The effects of adding two different types of phosphatidylcholine (PC) (purified from soybean lecithin, SPC, or marine fish roe, MPC) on growth, survival and osmotic stress resistance as well as lipid and fatty acid composition of postlarval Penaeus vannamei was determined. PC was added at a level of 1.5% in a semi-purified diet containing similar levels of essential fatty acids (EFA). A PC-free diet served as the control treatment. The supplementation of 1.5% SPC significantly improved growth and reduced sensitivity to osmotic stress. P. vannamei-fed MPC showed inferior growth compared to those fed SPC, but yielded better growth and survival than the PC-deprived shrimp. The addition of any of the PC types resulted in a...

Crecimiento y supervivencia de larvas de Argopecten nucleus alimentadas con diferentes dietas microalgales

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...

Effect of Spirulina platensis meal as feed additive on growth, survival and development in Litopenaeus schmitti shimp larvae

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...

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%...

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)

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...

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...

Few shrimp hatcheries successfully propagate captive broodstock on a commercial scale. Diets for acceptable maturation performance of Penaeus vannamei have typically relied on the inclusion of marine polychaetes (bloodworm) from Panama or Maine, USA, which are expensive and are of unpredictable supply. Studies were therefore undertaken at experimental and commercial scale to replace or supplement the polychaetes by frozen ongrown Artemia which were either non-enriched or bioencapsulated with specific boosters. In experiment 1 the control diet consisted of frozen squid only and was evaluated against broodstock diets where 60% of the squid was substituted by bloodworm or enriched Artemia biomass....
