Comparative ontogenetic development of two marine teleosts, gilthead seabream and European sea bass: New insights into nutrition and immunity

Gilthead seabream and European sea bass are two of the most commonly farmed fish species. Larval development is critical to ensure high survival rates and thus avoid unacceptable economic losses, while nutrition and immunity are also important factors. For this reason this paper evaluates the ontoge...

Sumario:Gilthead seabream and European sea bass are two of the most commonly farmed fish species. Larval development is critical to ensure high survival rates and thus avoid unacceptable economic losses, while nutrition and immunity are also important factors. For this reason this paper evaluates the ontogenetic development of seabream and sea bass digestive and immune systems from eggs to 73 days post- fertilisation (dpf) by assessing the expression levels of some nutrition-relevant (tryp, amya, alp and pept1) and immune-relevant (il1b, il6, il8, tnfa, cox2, casp1, tf, nccrp1, ighm and ight) genes. The results point to similar ontogenetic development trends for both species as regard nutrition and differences in some immunity related genes.
