Amélioration génétique et utilisation des aliments à base de végétaux en pisciculture ArchiMer
Le Boucher, Richard; Dupont-nivet, M.; Laureau, S.; Labbe, Laurent; Geurden, I.; Medale, F.; Chatain, Beatrice; Vandeputte, Marc; Quillet, E..
World fish farm production is growing rapidly. However, the supply of fishmeal and fish oil, the major ingredients of fish diets, has reached a limit because of the limits in the exploitation of wild fish stocks that cannot be increased to meet a growing demand. The main response, especially in Europe, has been the progressive replacement of fishmeal and fish oil by plant products. However, the strong reduction of growth and sometimes survival of fish fed highly substituted diets has urged research on the genetic potential for adaptation to plant-based diets. Recent results clearly demonstrate that fish can be selected for their capacity to grow when fed plant-based diets, even though the underlying mechanisms remain unknown. Genotype-diet interactions...

Des aliments à base de végétaux pour les poissons d’élevage ArchiMer
Medale, F.; Le Boucher, Richard; Dupont-nivet, M.; Quillet, E.; Aubin, Joel; Panserat, S..
World aquaculture is growing (+ 8% per year) to meet the increasing demand of fish for human consumption that capture by fisheries can no longer cover. Consequently, the need for aquafeed and feedstuffs is rising while volumes of fishmeal and fish oil, the traditional aquafeed ingredients, remain stable. More and more fishmeal and fish oil are substituted by plant products. Between 80 and 95% of fish meal can be replaced by a combination of plant protein sources providing the indispensable amino acids in sufficient quantity to meet the fish needs. Beyond this substitution rate, feed intake, feed efficiency and growth rate decrease and metabolic changes are observed despite the diets containing all the required nutrients. Fish oil can be replaced by a mix...

Genotype by diet interactions in European sea bass (Dicentrarchus labrax L.): Nutritional challenge with totally plant-based diets ArchiMer
Le Boucher, Richard; Vandeputte, Marc; Dupont-nivet, M.; Quillet, E.; Ruelle, Francois; Vergnet, Alain; Kaushik, Sadasivam; Allamellou, J. M.; Medale, F.; Chatain, Beatrice.
Aquaculture of carnivorous species has strongly relied on fish meal and fish oil for feed formulation; however, greater replacement by terrestrial plant-based products is occurring now. This rapid change in dietary environment has been a major revolution and has to be taken into consideration in breeding programs. The present study analyzes potential consequences of this nutritional tendency for selective breeding by estimating genetic parameters of BW and growth rates estimated by the thermal growth coefficient (TGC) over different periods with extremely different diets. European sea bass (Dicentrarchus labrax L.) from a factorial cross (1,526 fish) between 25 sires and 9 dams were used to estimate heritabilities and genotype by diet interaction. Starting...

Hepatic glucokinase is induced by dietary carbohydrates in rainbow trout, gilthead seabream, and common carp Inra
Panserat, S.; Medale, F.; Blin, C.; Breque, J.; Vachot, C.; Plagnes-Juan, E.; Gomes, E.; Krishnamoorthy, R.; Kaushik, S..
Glucokinase (GK) plays a central role in glucose homeostasis in mammals. The absence of an inducible GK has been suggested to explain the poor utilization of dietary carbohydrates in rainbow trout. In this context, we analyzed GK expression in three fish species (rainbow trout, gilthead seabream, and common carp) known to differ in regard to their dietary carbohydrate tolerance. Fish were fed for 10 wk with either a diet containing a high level of digestible starch (>20%) or a diet totally deprived of starch. Our data demonstrate an induction of GK gene expression and GK activity by dietary carbohydrates in all three species. These studies strongly suggest that low dietary carbohydrate utilization in rainbow trout is not due to the absence of inducible...

Nutritional and hormonal control of lipolysis in isolated gilthead seabream (Sparus aurata) adipocytes Inra
Albalat, A.; Gomez-Requeni, P.; Rojas, P.; Medale, F.; Kaushik, S.; Vianen, G.J.; van den Thillart, G.; Gutierrez, J.; Perez-Sanchez, J.; Navarro, I..
We examined the effects of diet composition and fasting on lipolysis of freshly isolated adipocytes from gilthead seabream (Sparus aurata). We also analyzed the effects of insulin, glucagon, and growth hormone (GH) in adipocytes isolated from fish fed with different diets. Basal lipolysis, measured as glycerol release, increased proportionally with cell concentration and time of incubation, which validates the suitability of these cell preparations for the study of hormonal regulation of this metabolic process. Gilthead seabream were fed two different diets, FM (100% of fish meal) and PP (100% of plant protein supplied by plant sources) for 6 wk. After this period, each diet group was divided into two groups: fed and fasted (for 11 days). Lipolysis was...

Postprandial utilization of energy susbtrates by a tropical catfish, Holosternum littorale : indirect calorimetry analysis IRD
Moreau, Yann; Medale, F.; Boujard, T.; Luquet, Pierre.
Indirect calorimetry method was used to measure postprandial utilization of energy substrates by atipa, #Hoplosternum littorale$ (#Callichthyidae$, Siluriform). A model was adjusted to the data on respiratory exchanges and nitrogen excretion for this purpose. As for other fish species, protein was actively catabolized after feeding during the 60 hr measurement time. As long as carbohydrates were available, atipa was also able to use these substrates for its energy metabolism. A gradual increase of contribution of lipids was then noticed. Over a 24 hr period following the food intake, a 30 g fish catabolized 90 mg of proteins and 43 mg of carbohydrates. At the same time, the results led to a synthesis of 3.7 mg of fat. An estimation of the increase of the...
