Daily patterns of ammonia nitrogen output of Siberian sturgeon Acipenser baeri (Brandt) of different body weights

International audience The daily pattern of ammnonia nitrogen outputs of five weight groups of Siberian sturgeon, Acipenser baeri was studied. Regardless of weight, there was a delay of 3 h between the start of feeding and the increase in ammonia output. The study showed that continuous feeding is s...

Description
Summary:International audience The daily pattern of ammnonia nitrogen outputs of five weight groups of Siberian sturgeon, Acipenser baeri was studied. Regardless of weight, there was a delay of 3 h between the start of feeding and the increase in ammonia output. The study showed that continuous feeding is suitable in sturgeon farms in terms of ammonia loadings. Le rythme quotidien des rejets d'azote d'ammoniaque de cinq groupes d'esturgeons sibériens de poids différents, Acipenser baeri, a été étudié. Quelque soit le poids, il y a un retard de 3 heures entre le début de l'alimentation et l'augmentation de la production d'ammoniaque. L'étude a montré que l'alimentation continue est adaptée aux fermes d'esturgeons en termes de charges d'ammoniaque.
