Estimates of heritability and genotype-environment interactions for body weight in sea bass (Dicentrarchus labrax L.) raised under communal rearing conditions

Autores: Saillant, Eric; Dupont Nivet, Mathilde; Haffray, Pierrick; Chatain, Beatrice.
Genetic parameters for somatic growth rate in sea bass were estimated in two experiments where 27 (year-class 1997) to 30 (year-class 1998) families of sea bass (3 dams mated with 9-10 sires according to a full factorial design) were raised mixed in the same tanks starting shortly before hatching (48 h post fertilization). Trials were performed under two temperature (experiment 1, 1997: group high temperature (HT) and group low temperature (LT)) and two density regimes (experiment 2, 1998: group high density (HD) and group low density (LD)) with a subset of the mating design (18 families) being reproduced in the two experiments. All the fish were genotyped at 3-6 microsatellite loci which allowed them to be assigned to the individual breeders used in the...

Facing the finite size of fisheries resources, the important increase of aquaculture production during the last decades has led to the evolution of feed composition with an increasing substitution of fish meal and fish oil with terrestrial plant products. During the same period, selective breeding has been developed in fish and major improvements were achieved on growth, resulting in 4 to 20 % gain per fish generation (Olesen, Gjedrem, Bentsen et al. (2003); Chevassus, Quillet, Krieg et al. (2004)), and also on health and flesh quality traits.

Plant-based diet in trout (O. mykiss): are there genotype-diet interactions for main production traits when fish are fed marine vs plant-based diets from the first meal ?

To face future decrease of marine resources, replacement of fishmeal and fish oil by plant products is nowadays worldwide priority for the aquaculture of carnivorous fish, especially salmonids. Genetic variability has been recently evidenced for growth ability on plant-based diet and pointed out potential genetic gains. In a context of fast feed evolution, this work compares heritabilities of growth parameters between rainbow trout fed with diet containing fish oil and fish meal and fish fed on diet devoid of marine products. Assessment of genotype diet interaction informs on potential family reranking between diets and potential consequences on current breeding programmes.
