| Superovulatory response, production and embryo quality and the effects of seasonal changes on embryo production of Nellore cows fed on either linseed (n-3) or canola seeds (n-6) were evaluated. Sixteen Nellore cows (550 ± 48.0 kg) were fed on three diets: control diet (CON), diet with linseed (LIN) and diet with canola seed (CAN) during four seasons. There was no difference in superovulatory response and in total corpora lutea produced when diets are taken into consideration. The number of cows that responded to superovulatory treatment was higher in the winter (93.8%) than in the summer (62.5%). No difference with regard to the three diets existed on the average number of total structures (6.20, 4.96 and 6.50), unfertilized structures (2.53, 1.17 and... |

| Este trabajo se realizó con juveniles de camarón blanco P. schmitti de 0.39 g de peso promedio, colocados en corrales de 20 m2 situados los mismos dentro de estanques de tierra de 0.5 Ha, a una densidad de 8 camarones/m2 durante 57 días, con el objetivo de determinar el nivel proteico adecuado para dietas comerciales en condiciones semi-intensivas de cultivo. Los estanques fueron preparados y tratados según las normas establecidas en la producción. Se emplearon 6 tratamientos con 3 réplicas cada uno (una en cada estanque) que contenían 19, 22, 25, 28, 31 y 35% de proteína. Se empleó la harina de pescado como proteína animal y como vegetal la soya. Al final del ensayo se obtuvo que los camarones alimentados con niveles proteicos de entre 28 y 35% alcanzan... |

| Successful bivalve larval growth and survival depend on stored reserves provided by diet. The aim of this study was to evaluate the effects of microalgal diet on growth, survival, together with biochemical and fatty acid composition during larval development in grooved carpet shell (Ruditapes decussatus). Four mono- and multi-species diets were tested: (1) Isochrysis galbana, Pavlova lutheri and Chaetoceros muelleri (1:1:1, IPC); (2) I. galbana, P. lutheri and C. muelleri (1:1:2, IP2C); (3) I. galbana and P. lutheri (1:1, IP); (4) C. muelleri (C). Our results showed that feeding regime greatly influenced larval growth and survival, as well as biochemical and fatty acid composition. Higher growth and survival rates were observed in the IPC, IP2C and C... |

| Afin de réduire le coût des aliments aquacoles, nous avons procédé à la substitution d’une matière première végétale importée: le tourteau de soja (TS) par un sous produit local : la farine de tomate (FT). L’expérience est menée sur des juvéniles de Tilapia (Oreochromis niloticus) monosexe mâle ayant un poids moyen initial de 20,54 ± 0,08 g. (poids moyen ± ES), et elle consiste à tester 4 régimes alimentaires isoprotéiques (27 % de protéines) et isoénergétiques (17 KJ/g) contenant différents taux de farine de tomate: 0 % (aliment témoin), 10 %, 20 % et 30 % noté respectivement A0, A10, A20 et A30. Ces aliments sont testés, durant 75 jours. A la fin de l’expérience les poids moyens finaux ont atteint des valeurs comprises entre 98,62 g et 129,77 g selon... |

| This study aimed to evaluate economically the inclusion of prebiotics, probiotics and symbiotics in diets of Nile tilapia (4.07 ± 0.30 g), at two stocking densities (0.6 and 1.2 kg m-3). A total of 288 fish were distributed over 32 tanks (40 L) in a completely randomised design, in a 2 x 4 factorial (stocking density x additives), with four replications, over six weeks. The following were evaluated: total feed consumption (FC), final biomass (FB), relative gain in biomass (RGB), apparent feed conversion (AFC), survival rate (SUR), average cost of feed per kg of live weight gain (ACF), total cost of feed (TCF), total cost of production (TCP), gross income (GI), operating profit (OP) and economic efficiency index (EEI). No effect was seen the evaluated... |

| Lors de l'introduction d'une espèce en élevage, outre la maîtrise de sa reproduction, il convient de déterminer ses besoins nutritionnels en vue de définir un aliment adapté. La connaissance préalable du régime alimentaire de l'espèce concernée dans son habitat naturel est alors indispensable. La nature même de ce régime est très variable et fonction du milieu, de la saison, de l'espèce et de son stade physiologique. Cette fiche technique a pour but de présenter succinctement trois espèces de poissons habituellement élevés en Côte d'Ivoire et la nature de leur régime alimentaire en milieu naturel. Il s'agit du Tilapia Oreochromis niloticus, du Mâchoiron Chrysichthys nigrodigitatus et du Silure Heterobranchus longifilis. |

| The effects of increasing levels of dietary phospholipids (PL) on the reproductive performance, egg and larval quality, and lipid composition of females of the freshwater prawn <i>Macrobrachium rosenbergii</i> were investigated. Three isolipidic diets containing similar amounts of highly unsaturated fatty acids but varying levels of PL (0.8, 2.4 and 4.6%) were fed during 180 days to three groups of eight females originating from Thai ponds. No significant differences were observed for fecundity, egg size and hatchability, starved larvae size, and size, survival and tolerance to stress of 8 day-old larvae. Similarly, no major differences in the lipid composition of the midgut gland, ovaries and muscle tissue of females could be detected. Results... |

| Many birds in breeding seasons engage in vigorous dawn singing that often turns to a prominent chorus. We examined dawn chorus variation of avian assemblages in a tropical montane forest in Taiwan and tested the hypothesis that onset sequence is affected by eye sizes, foraging heights, and diet of birds. Chorus onset and duration varied between sampling months, but generally peaked in the prime breeding season. Overall dawn chorus length increased with, but mean duration per species was negatively correlated with, species richness. The inter-correlation among trait variables in phylogenetic independent contrasts was calculated and examined. Both foraging height and relative eye size were selected as positively explanatory factors, but no dietary effects... |

| A beneficial effect of dietary phospholipid (PL) supplementation in purified diets in terms of survival, growth, resistance to stress tests, and occurrence of deformities has been demonstrated in larval and juvenile stages of various species of fish and crustaceans. The exact determination of PL requirements in larvae is complicated due to the difficulty to bio-encapsulate PL in live prey. Furthermore, the great variety in purity and composition of the PL sources, and the experimental conditions (such as diet formulation and extent of co/prefeeding with live food) makes it difficult to compare requirements determined with artificial diets. Larval stages are extremely sensitive to a dietary PL deficiency and require higher levels of dietary PL than... |

| In this study baker's yeast was evaluated as a substitute for live <i>Dunaliella tertiolecta</i> algae in the culture of the brine shrimp <i>Artemia</i> . Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for <i>Artemia</i> by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by <i>Artemia</i> . Chemically treated baker's yeast offers promising possibilities as a substitute for... |

| In the frame work of a PhD thesis dealing with the use of artificial diets as an algal substitute for mollusks, the Laboratory of Aquaculture & Artemia Reference Center (State University of Ghent, Belgium) is organizing an inquiry which aims at drawing up an inventory of algal substitutes, their cost and applications, and their relative importance and cost-efficiency compared to live algae. The questionnaire has been sent to more than 200 people who are involved in the practice of culturing bivalves. The results will be treated as part of the PhD work and a free copy of the resulting report will be sent to all those who are returning the form. The questionnaire will be presented at Aquaculture Europe 1991 in Dublin under the form of a poster. The... |
