Última Comparison of brown trout (Salmo trutta) reared in fresh water and sea water to freshwater rainbow trout (Oncorhynchus mykiss) .1. Growth and nitrogen balance ArchiMer 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...

Les salmonidés peuvent être classés en deux grands groupes : - ( 1) les espèces ou variétés "sédentaires" d'eau douce, non affectées par un comportement migratoire et passant leur vie entière en systèmes dulçaquicoles ; - (2) les especes ou variétés affectées par de profondes modifications physiologiques, la smoltification, les préadaptant à la vie en milieu océanique et se terminant par la migration active vers la mer. Le présent travail a consisté à effectuer des transferts d'eau douce en eau de mer de diverses espèces de ces deux groupes à différentes étapes de leur cycle de développement et à étudier corrélativement les variations consécutives de leur équilibre hydrominéral et leurs performances ultérieures. Les résultats de cette étude ont permis...

Ano: 1987 URL: http://archimer.ifremer.fr/doc/00443/55500/57046.pdf Voluntary feed intake and discrimination of diets containing a novel fluoroquinolone in self-fed rainbow trout ArchiMer Boujard, Thierry; Le Gouvello, Raphaela. The objective of the study was to evaluate the capacity of rainbow trout to discriminate diets containing micro-granulated or powdered novel fluoroquinolone in comparison with a positive (containing sulfamerazine sodium) and a negative control (placebo). In a first trial, groups of trout had access to a self-feeder containing the placebo feed for 10 days, and then to one of the four feeds during another period of 10 days. Fish reduced their voluntary feed intake (VFI) by more than 50 % when they had access to the positive control, and by more than 20 % when they had access to feed containing micro-granulated premix. There was no significant decrease in VFI when the fish had access to feed containing powdered premix, but in this latter case, an increase in...

Ano: 1997 URL: http://archimer.ifremer.fr/doc/00335/44651/57341.pdf Voluntary feed intake, nitrogen and phosphorus losses in rainbow trout (Oncorhynchus mykiss) fed increasing dietary levels of soy protein concentrate ArchiMer Medale, Francoise; Boujard, Thierry; Vallee, Frédéric; Blanc, Denise; Mambrini, Muriel; Roem, Arjen; Kaushik, Sadasivam. High energy extruded diets were formulated to contain the same level of protein supplied either by soy protein concentrate (SPC) or fish meal. Three experiments were performed in order to measure voluntary feed intake and feed waste, faecal losses and soluble losses of nitrogen and phosphorus in rainbow trout (average body weight: 100 g). Voluntary feed intake and growth performance of fish fed with demand feeders were not different when diets contained 0, 50 or 75 % SPC instead of fish meal. Total replacement of fish meal by SPC led to a significant decrease in feed intake and resulted in poor growth. This was partly due to methionine deficiency in the SPC based diet. With the addition of crystalline DL-methionine in the diets, an improvement of feed...
