Abstract

TAVARES-DIAS, Marcos; MARTINS, Maurício L.  and  MORAES, Flávio R.. Hepatosomatic and splenosomatic relation of intensively cultivated teleost fishes. Rev. Bras. Zool. [online]. 2000, vol.17, n.1, pp.273-281. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81752000000100024.

The mean values of hepatosomatic relation (HSR), splenosomatic relation (SSR) and relative condition factor (Kn) in Nile tilapia (Oreochromis nilolicus Trewavas, 1983); pacu (Piaractus mesopolamicus Holmberg, 1887); piauçu (Lepori-nus macrocephalus Garavello & Britski, 1988) and tambacu hybrid (P. mesopotamicus male x Colossoma macropomum Cuvier, 1818 female) are described. The experiment was carried out from feefishing farm situated in Franca, São Paulo State, Brazil. Nile tilapia showed the greatest HSR compared to pacu, piauçu and tambacu. Although, in the last three fishes the relation was similar. The SSR between tilapia and piausu was similar, but smaller than observed in pacu and tambacu. Nevertheless, SSR in pacu and tambacu was different. The hepatic weight/body weigth relation and hepatic weight/body length relation presented positive correlation in ali studied fishes. The splenic weight/body weigth relation and splenic weight/body length relation were not significam (P>0.05) in Nile tilapia, pacu and tambacu, but highly significant in piauçu (PO.01).

Keywords : Hepatosomatic relation; Splenosomatic relation; Oreochromis; nilolicus; Piaractus mesopotamicus; Leporinus macrocephalus; tambacu hybrid.
