Evaluation of behavioral changes induced by a first step of domestication or selection for growth in the European sea bass (Dicentrarchus labrax): A self-feeding approach under repeated acute stress
Provedor de dados: 5
Autores: Millot, Sandie; Pean, Samuel; Leguay, Didier; Vergnet, Alain; Chatain, Beatrice; Begout, Marie-laure.
Among other strategies to improve fish welfare in rearing environment, domestication and/or selective breeding was proposed to minimize fish responsiveness to husbandry practices. To verify this hypothesis on a recently domesticated specie, the sea bass, Dicentrarchus labrax, L., an experiment was realized, using four populations differing according to their level of domestication or selection: one population produced from wild parents (Wild), one population produced from parents domesticated for one generation (Domesticated) and two produced from parents selected for growth for one generation (Selected A and Selected B). The experiment was carried out over 91 days with 600 fish (50 fish per tank, 150 fish per population). After a control period, the fish...

Self-feeding behavior changes induced by a first and a second generation of domestication or selection for growth in the European sea bass, Dicentrarchus labrax
Provedor de dados: 5
Autores: Millot, Sandie; Pean, Samuel; Chatain, Beatrice; Begout, Marie-laure.
Among the strategies that can be used to improve fish welfare in a rearing environment, domestication and/or selective breeding was proposed to minimize fish responsiveness to husbandry practices. To verify this hypothesis on a recently domesticated species, the sea bass Dicentrarchus labrax, two experiments were realized, each using two populations differing according to their level of domestication or selection. For the first experiment, we used one population produced from wild parents (Wild; initial body mass: 106 +/- 3 g), and one population from parents selected for growth for one generation (Selected 1; initial body mass: 129 +/- 4 g). For the second experiment, we used one population produced from parents domesticated for two generations...
