dc.description.abstract | In the Morona Santiago Province , Macas cantón, farm " Plaza Twinza". Arapicos sector, the productive behaviour of the piaractus brachypomus ( white cachama) under different sowing densities was evaluated. A completely at random design with four treatments was applied in a 200-m2 pool divided into four parts i.e. the treatments. To measure the statistical differences a sample of 10 chacamas in each pool was analyzed. In the investigation 2.500 cachamas during 105 days with an average initial weight of 0.99 g and average size of 1.95 cm were evalualed. They were fed on the comercial balanced feed ABA ( 45% raw protein) during the initial phase and balanced feed ABA ( 32% raw protein ) during the development phase. The results showed highly significant differences for the weight (169.60g) size ( 15 cm) and weight gain ( 39.65g) variables which represent a daily gain of 1.3 g/fish/day, and the fish consumed 76.33g feed, showing a feed conversión of 1.62. Upon finishing the investigation the Tukey separation determined the T4 ( 5 fish/m2) as the best treatment since the best productive behaviour was reported in the whole investigation. Moreover, economically, it was determined ,that the T4 treatment has a fruitful recovery with a B/C of 1.13. This is why it is recommended to sow at a density of 5/fish/m2 to have the best profit of all the resources in the white cachama raising | |
