Abstract (EN): Histological examination of liver tissue originating from juvenile European sea bass (Dicentrarchus labrax L.), fed experimental diets with a varying starch source displayed significant changes in general morphology and glycogen distribution. Fish fed diets containing a graded inclusion of a pea seed meal showed clear evidence of enhanced glycogen deposition in the liver compared to Fish receiving a semi-purified starch source in the control diet. Lipid accumulation was also more evident in this group and the general architecture of the livers was noticeably different between the control fish and those fed diets with the pea seed meal at both levels. This was particularly relevant to the density and profile of hepatic sinusoids. The comparative features between the cultured seabass under laboratory conditions and the livers of wild fish are discussed.
