Rendimiento en canal y fileteado de la tilapia (Oreochromis niloticus) variedad Chitralada producida en el estado Trujillo, Venezuela

an experiment was carried out in order to evaluate the carcass yields and filleting of the tilapia (oreochromis niloticus strain: chitralada) with weights among 250-400g (range: 250-300, 300-350 and 350-400g), cultivated under intensive conditions in trujillo state, venezuela; using a completely randomized design with 60 measured animals. the morphometric measured parameters were: total length (lt), standard length (ls), head length (lc), head height (ac), body thickness (eh), body longitude (lh) and body height (ah); the variables related with the weight (in g) were: weigh fresh (pf), carcass weight (pc), body weight (pt), weight of the clean trunk (tse), fillet weigh (pfi) and component of residuals; the parameters relating with yields were evaluated to: carcass yield (%rc), fillet yield according to fresh weight (% rpf) and yield of the fillet according to the carcass (%rfpc). the morphometric parameters showed significant differences (p<0,05), exception of eh and ah. no differences (p>0,05) in the variables related with weight of gills and fins were observed. no differences regarding the yield according to the variables of corporal yield were observed (p>0,05). the hight morphometric and weight values were observed in animals with 350-400g of live weight. however, the hight size presented marginal influence in yield results.
