ROUX, J.P. et al. Larvicultura intensiva de sábalo (Prochilodus lineatus) con diferentes densidades de cría. Rev. vet. [online]. 2015, vol.26, n.2, pp.143-146. ISSN 1669-6840.

The present work intends to evaluate the effect of stocking density on survival and final weight of Prochilodus lineatus larvae grown in an intensive system. Four densities of larvae were evaluated: 25, 50, 100 and 200 larvae/liter (T1, T2, T3 and T4, respectively). Twelve small volume tanks were used. At the end of the experiment all the fish were counted and weighed, data used to estimate the survival rate and the average final weight, respectively. For average weight, no significant differences were detected between treatments, while for the survival rate, T3 had better performance than T4. Groups T1 and T2 had intermediate values and did not differ from the rest. Under the rearing conditions of this study, no differences in larvae average weight were found for the considered densities
