Digestibilité des protéines et disponibilité des acides aminés de quelques matières premières chez le bar (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Spyridakis, P; Gabaudan, J; Metailler, Robert; Guillaume, J.
Protein digestibility of soyabean meal, casein-gelatin mixture and fish hydrolysate was tested in the European sea bass, using increasing substitution levels in a reference diet. The protein digestibility of the latter composed of Norwegian fish meal had already been established (91 %). An accurate estimation of the apparent digestibility coefficient was made by linear regression, for the casein-gelatin mixture and soyabean meal, but not for fish hydrolysate (non significant correlation, p &gt; 0.05). Protein digestibility estimated by extrapolation varied with the substitution level. The estimations obtained with the highest level used for each ingredient were close to those obtained by linear regression. However they exhibited a high variability for...

Influence of dietary bulk agents (silica, cellulose and a natural zeolite) on protein digestibility, growth, feed intake and feed transit time in European seabass (Dicentrarchus labrax) juveniles
Provedor de dados: 5
Autores: Dias, Jorge; Huelvan, Christine; Dinis, Maria; Metailler, Robert.
The incorporation of various bulk agents by substitution of an equivalent amount of the basal mixture was studied in terms of protein digestibility, growth performance and body composition in European seabass (Dicentrarchus labrax) juveniles. During the growth trial, triplicate groups of 40 seabass (mean initial weight: 7.0 g) were grown in seawater (salinity: 35; temperature: 18 degrees C) over 60 days. Fish were hand-fed, three times a day, one of seven experimental diets. Bulk agents tested at 10 or 20 % level of incorporation were silica, cellulose and a natural zeolite (chabamin). Feeding rates were adjusted in proportion to the percent dilution of the control diet without bulk incorporation. The incorporation of the bulk agents, at a 10 and 20 %...

Comparison of brown trout (Salmo trutta) reared in fresh water and sea water to freshwater rainbow trout (Oncorhynchus mykiss) .1. Growth and nitrogen balance
Provedor de dados: 5
Autores: Dosdat, Antoine; Metailler, Robert; Desbruyeres, Elisabeth; Huelvan, Christine.
Brown trout and rainbow trout (average weight 100 g) were reared in fresh water at 12 degrees C under the same conditions before transfer of brown trout to sea water, in order to compare nitrogen utilisation in the two species. Apparent protein digestibility (ADC), nitrogen (ammonia and urea) excretion, protein productive value (PPV) and actual observed nitro en mass balance were determined. Rainbow trout raised in fresh water had a higher growth rate (1.1 vs 0.8%. d(-1)), better food conversion ratio (0.7 vs 1.0), better ADC (91 vs 85%) and PPV (45 vs 35%) and lower ammonia excretion rates than brown trout reared in fresh water. Transferring brown trout to sea water induced lower PPV (30%) and ammonia and urea excretion. Salinity did not modify metabolic...

Culture of turbot (Scophthalmus maximus)
Provedor de dados: 5
Autores: Person-le Ruyet, Jeanine; Baudin-laurenc, Félix; Devauchelle, Nicole; Metailler, Robert; Nicolas, Jean-louis; Robin, Jean; Guillaume, Jean.
Turbot, Scophthalmus maximus Rafinesque, 1810: Psetta maxima Linnaeus, 1758, is a marine demersal carnivorous flatfish of the Scophthalmidae family, relatively abundant in Europe: from 68°N down to Morocco 30°N. It is also abundant in the Mediterranean Sea as far as Turkey. But it is lacking in the Black Sea, where two very close species, S. maeoticus and S. ponticus, are naturally found (Figure 1). Turbot are caught on sand, gravel, or mixed bottoms at a depth of 20 to 70 m. The total annual catch is less than 10,000 for all Europe in spite of the high market price: from 10 to 25 U.S. $/kg according to the country and the size of the fish (0.65 to 15 kg). Turbot was selected for aquaculture in the early 1970s, both in the United Kingdom and France due to...

Impact de la pisciculture marine intensive sur l'environnement : contribution à la modélisation de l'utilisation de l'azote par le turbot
Provedor de dados: 5
Autores: Dosdat, Antoine; Tetu, N.; Metailler, Robert; Huelvan, Christine; Desbruyeres, Elisabeth; Le Delliou, Herve.
Ce document présente une étude visant à déterminer le flux de nutriments produits par un élevage de turbots en conditions contrôlées. Les paramètres d'excrétion et de production de fèces ont été abordés en fonction des quantités d'aliment ingéré, en même temps que l'excrétion d'azote corporel. L'étude montre que le turbot est un animal plus économe que la truite arc-en-ciel pour ce qui concerne l'utilisation des protéines. Ceci est explicable par des particularités physiologiques. L'utilisation de modè les "salmonidés" pour l'estimation de l'impact environnemental des piscicultures marines est donc déconseillée.

Accoutumance de jeunes soles (Solea solea) à différents aliments inertes après achèvement de la métamorphose
Provedor de dados: 5
Autores: Girin, Michel; Metailler, Robert; Nedelec, Jacqueline.
A comparative test of various inert diets was performed on 9 batches of 150 one month old soles, wheighing an average 42 mg, and feeding on live brine shrimps. It lasted for 2 months, in 60 l square tanks, with sand bottoms. . A succession of frozen natural feed, ending with the Bivalve Laevioardium arassum, was compared to 2 different artificial diets, offered as dry pellets. The inurement to the pellets was facilitated by an incorporation of various meals, used as flavourings, during a 6 weeks transitory period. - At the end of the experiment, the best result, 98 % survival, average weight . 1.10 g, was obtained with the natural feed. The best flavourings for dry pellets were Laevi- cardium arassum and the Polyahaete Nephthus hombergii, with 70 %...

Influence de divers aliments composés sur la croissance et la survie d'alevins de bars (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Metailler, Robert; Mery, Camille; Depois, Marie-noëlle; Nedelec, Jacqueline.
About twenty different prepared diets are given to young sea-basses weighing from 400 mg to a few grams, in 3 experiments, during which the growth and survival of the fish are regularly checked. The protein requirements of the species range around 47-SO % of the diet, and the energetic requirements seem to the covered by 11 to 12 % fat. The diets are mainly composed of fish meal. However fish autolysates and yeasts seem to give interesting results when incorporated into the diet.

Croissance et survie du homard (Homarus vulgaris) pendant les quinze premiers stades en élevage et sous alimentation composée
Provedor de dados: 5
Autores: Le Gall, Jean-yves; Mauviot, Jean-charles; Metailler, Robert; Berthou, Patrick.
Juvenile lobsters were reared for 8 months individually in separate tanks in order to obtain separate estimates of growth. Five batches were studied separately according to the type of diet : deep-frozen krill, paste, ¿try pellets and moist pellets. Growth data were collected over 15 first molt stages for each type of prepared diet. Observations deal with size and weight increments at moult and with weight/length relationships. Regression of total lengths over carapace lengths were fitted in each case.

Effect of dietary inulin and oligosaccharides as prebiotics for weaning turbot, Psetta maxima (Linnaeus, C. 1758)
Provedor de dados: 5
Autores: Mahious, A.s.; Gatesoupe, Joel; Hervy, Magali; Metailler, Robert; Ollevier, F.
Preliminary experiments were undertaken to investigate the effect of dietary inulin (Raftiline ST), oligofructose (Raftilose P95) and lactosucrose on the growth and intestinal bacteria of the marine carnivorous turbot, Psetta maxima. Turbot larvae were weaned on compound diets containing 2% Rafiline ST, 2% Raftilose P95 or 2% lactosucrose; 2% cellulose was the carbon source in the control group. The final mean weight of the group weaned with Raftilose P95 was significantly higher than those observed with the other diets. The bacterial load was highly variable in weaning turbot, especially with respect to the putative Vibrio spp. growing on TCBS agar which, in general, seemed to be dominant. Of the total load of bacterial isolates from turbot weaned on...

Comparison of brown trout (Salmo trutta) reared in fresh water and sea water to freshwater rainbow trout (Oncorhynchus mykiss): II. Phosphorus balance
Provedor de dados: 5
Autores: Dosdat, Antoine; Metailler, Robert; Desbruyeres, Elisabeth; Huelvan, Christine.
Brown trout and rainbow trout (average weight 100 g) were reared in fresh water at 12 degrees C under the same conditions before transferring brown trout to sea water, in order to compare phosphorus utilisation in both species. Apparent phosphorus availability, orthophosphate excretion and phosphorus accretion in the fish were directly determined. Thus, actual phosphorus mass balance was built. Rainbow trout raised in fresh water had a higher phosphorus retention coefficient (maximum 50 %) than brown trout reared in fresh water (maximum 45 %). Transferring brown trout to sea water induced a reduction in phosphorus retention (maximum 39 %), Orthophosphate excretion, ranging 7-20 mg phosphorus per kg wet weight per day, represented 10-20 % of ingested...
