Caracterización del desempeño productivo de juveniles de chame (Dormitator sp) bajo dos densidades en biofloc adicionados con micro-algas

Abstract

Growing chame (Dormitator sp.), It is important commercially, in the north of the province of Manabi, being a fish which by its nature is adapted to the richest ecosystems in organic matter. This study was conducted by implementing a system biofloc, to reduce water use and increase density, and two treatments with closed system with two replicates each were established: First treatment (t1 and t2) with a density of fishes of 45 org / m3 and the second treatment (t3 and t4) with 86 org / m3, adding to the beginning of the experiment and biofloc alga Tetraselmis suecica daily balanced food is shrimp to 22% protein and autoclaved molasses. The results showed that treatment 1 with lower seed (t1 and t2) had better growth than treatment 2 with the highest density of organisms (t3 and t4).
