Efecto del alimento vivo (drosophila melanogaster ) sobre el crecimiento de alevines de tilapia en comparación con dietas comerciales.

Abstract

This study evaluated the effect of the fruit fly (Drosophila melanogaster) on the growth and survival of Nile tilapia (Oreochromis niloticus) fry, compared to a commercial balanced feed and a mixed diet. The research was conducted using a completely randomized design (CRD) with three treatments (TD, TB, TBD) and two replicates per treatment, over a period of 30 days. Variables such as weight, length, survival rate, and water quality parameters were recorded. The results showed that fry fed exclusively with commercial feed achieved significantly higher weight and length compared to those fed solely with fruit flies. However, the mixed diet (50% live food and 50% commercial feed) exhibited intermediate growth performance, suggesting that partial use of fruit flies could be viable as a protein supplement. Survival rates did not show significant differences among treatments, indicating that all diets supported adequate organism viability. It is concluded that the use of fruit flies as a complementary feed represents a feasible and sustainable alternative to improve nutrition in small-scale aquaculture systems, especially in contexts with limited access to ommercial inputs. Its implementation could help reduce production costs and diversify food sources during the fry stage.
