Adaptations biochimiques intestinales chez la truite: Influence de l'aliment et de la salinite sur quelques proprietes membranaires

Liao, I; Liu, F.

In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Alternativas para obtener alimentos más eficientes en el engorde semintensivo del camarón blanco (Litopenaeus Schmitti)

Leray, C.

The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

Aquaculture of red tilapia Oreochromis sp. in marine environments: State of the art.

Leaute, Jean-pierre.

Stomach contents of juveniles of sea bass (Dicentrarchus labrax ) and common dab (Limanda limanda ) collected during September 1982 from Bay of Somme and the neighbor coast to Penly, were examined. The most part of the diet of young sea bass are the crustaceans, Sedentary polychaetes appear to be the major food item for common dab. For these two young predator species, food preferences tend to change early: cumaceans, then common edible shrimp, for sea bass, Tube worm tentacles, then part of whole individuals are preferred by common dab.

In this study baker's yeast was evaluated as a substitute for live Dunaliella tertiolecta algae in the culture of the brine shrimp Artemia . 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 Artemia 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 Artemia . Chemically treated baker's yeast offers promising possibilities as a substitute for...

Comparison of phosphatidylcholine purified from soybean and marine fish roe in the diet of postlarval Penaeus vannamei Boone

OMA

Coutteau, P.; Kontara, E.K.M.; Sorgeloos, P..

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...

Dawn chorus variation in East-Asian tropical montane forest birds and its ecological and morphological correlates

Telahigue, K.; Rabeh, I.; Chetoui, I.; Romdhane, M.S..

Dans le présent travail, les profils lipidiques des acides gras du pétoncle Flexopecten glaber récolté dans la lagune de Bizerte pendant le mois de mai 2007 ont été déterminés. Les pourcentages des différents groupes d’acides gras dans les organes (manteau, muscle adducteur, gonade, branchies et glande digestive) ont été calculés. Les résultats de la chromatographie en phase gazeuse ont révélé des pourcentages élevés en C20:5n-3 et en C14:0 et le rapport C22:6n-3/C20:5n-3 (DHA/EPA) est inférieur à 1, au niveau de la glande digestive du bivalve. Ceux-ci nous ont permis d’en déduire que le régime alimentaire de ce bivalve est essentiellement basé sur les diatomées. Les pourcentages les plus élevés des acides gras polyinsaturés de la série n-3 (EPA et DHA...

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...

DIETARY EVOLUTION OVER TIME IN EUROPE, BETWEEN CYCLOPS AND PHAECIANS . AN OUTLOOK ON THE ROLE OF SUPPLY-SIDE FACTORS IN DRIVING CHANGES IN THE FOOD PATTERNS

AgEcon

Finardi, Corrado; Arfini, Filippo; Turrini, Aida.

The present study intends to shed light, both from a descriptive and investigative point of view on the dietary evolution taking place in Europe during last 45 years, using secondary data from FAO FBS, which can cover the entire time span considered and allow for several extrapolation and timeseries analysis, differently than single survey data.. After a clustering of selected european national diets, using specific metrics with respect both to internal and external variety (as measured by appropriate indicators), we intended to check the actual distance that average, national diets have in front of the so called Food Pyramid, which consists in a balance of several food items in adequate proportions and in fact glorifies the healthy virtues of the...

Distribución, áreas de concentración y estructura de la población del abadejo (Genypterus blacodes)

Early weaning of marine fish larvae onto microdiets: Constraints and perspectives

Renzi, M.A..

The "abadejo" is one of the species that has been traditionally exploited in the Argentine Sea. Although the capture was not very important, it has been increased in the last years. In this work, the structure of the concentration areas of summer, spring and winter distribution and other biological items were analyzed, basing on the data collected during cruises effected by R/V "Walther Herwing" and R/V "Shinkai Maru" in these waters during 1978/79. Winter and spring distribution patterns showed the highest concentrations located between 41º and 48º SL, specially on the slope. Summer distribution pattern showed the concentration areas located between 43º30' and 48º30' LS shifted rather to the coast when comparing to the previous one. During the winter, in...

Ecomorphology and resource use by dominant species of tropical estuarine juvenile fishes

Person, L.

Weaning small sized marine fish larvae at first feeding directly onto compound pellets is still difficult, while good results can be obtained when used in combination with live prey or when a prefeeding period on live prey is provided up to a size of about 2-3 mg. Microdiets are generally well ingested as their acceptability and visual detection may be improved using feeding activators and increasing good perception contrast. In theory, food may be processed to have a correct nutritional balance, selection of high digestible components is very important as larval digestive system is not fully functional during the first 2 or 3 weeks of life.

Eleven ecomorphological attributes and diet of seventeen juvenile fish species were examined to test the hypothesis that morphological patterns determine resource uses in estuarine habitats. Species were separated according to the apparatus to food capture and habitat use (benthic or pelagic) in three different groups: (1) a group with depressed fish body, strong caudal peduncle and enlarged pectoral fins; (2) a second group laterally flattened with a wide protruding mouth, and (3) a third group strongly flattened with small pectorals fins. The following six trophic groups were organized based on prey categories: Zooplanktivores, Benthivores, Omnivores, Detritivores, Macrocarnivores and Insectivores. Significant results (PERMANOVA) between ecomorphological...

In spite of its aquaculture potential, the larval rearing of greasy grouper (Epinephelus tauvina) remains problematic and is not yet commercially feasible. The low and unpredictable larval survival is due to difficulties encountered in spawning the broodstock, the small size of the larvae at first feeding, and the high sensitivity of the larvae until day 45. The nutritional requirements for the broodstock as well as for the young larvae are still enigmatical. In this presentation the impact of supplementing the highly unsaturated fatty acids (HUFA), eicosapentaenoic (EPA), and docosahexaenoic acid (DHA) to the broodstock and larval diets is illustrated.
