Evaluation of Ovopel as an agent that induces Coporo spawning, using different application protocols
Abstract
Coporo, Prochilodus mariae, is one of the species of greatest interest for fish farming in Venezuela, due to the high commercial demand it presents and its potential for cultivation in closed environments. However, for fish farming to be efficient and sustainable, it is necessary to have a reliable supply of fingerlings, without counting on contributions from the natural environment, since the massive capture of juveniles could alter wild populations. Coporo is a rheophilic species, since it presents migrations along large rivers associated with reproduction. This species is unlikely to spawn spontaneously in controlled environments; it is necessary to induce it by applying conventional hormonal induction techniques (Zaniboni-Filho and Nuñer, 2004).
