COMOLLI, J.A et al. Larvicultura semi-intensiva de sábalos (Prochilodus lineatus) con diferentes regímenes alimenticios. Rev. vet. [online]. 2016, vol.27, n.2, pp.103-106. ISSN 1669-6840.

With the purpose of obtaining a better rate of growth and survival guaranteeing a good quality and quantity of alevins, this case has compared the growth and the survival of P. lineatus larvae while exposed to three different alimentary regimes during 29 days of semi-intensive larviculture. The ponds were fertilized with bovine manure to produce natural food (AN) and were identified as treatment one (T1) only AN, T2 AN more balanced food (AB) with 28 of gross protein (PB), T3 AN more AB whit 32 of PB. Concrete ponds were utilized with a density of 100 larvae/m2. They were fed three times per day and oxygen and temperature parameters were registered twice a day. At the end of the experiment middleweight and survival rate were measured. T2 and T3 had a higher middleweight, no difference was found on their survival rate.

Keywords : Prochilodus lineatus; fertilization; fingerlings; percent of protein; survival rate.
