Desarrollo e Implementación de un Manual de Buenas Prácticas de Producción Acuícola en Tilapias del Proyecto Piscícola Jacalurco, en la Provincia de Pastaza

Abstract

At he installations of the Jacalurco Fish Development Project of the Pastaza Provincial Council, located at the Putuime Community, Madre Tierra Parish, Pastaza Canton, a Manual on Good Water Production Practices in Tilapias was developed through the check list applying before and after evaluating the technical parameters which involved the physical and chemical and microbiological analysis of the tilapia feed, which permitted to determine an increase in the alevin production due to the training process. The water hardness was reduced from 39.5mg / l to 31.60mg / l; the suspensions solids decreased from 149.10mg / to116.80mg / l; the iron and ammonium quantity decreased from 1.10mg / to 0.48mg / l and from 0.22% to 0.10% mass respectively as well as the phosphorous quantity from 1.08mg / l to 0.29mg / l. the oxygen solved in water increased from 1.92mg / l to 2.62mg / l. the mesophyll aerobe presence was controlled in the tilapias decreasing from 14593.00UFC / g to 386.00UFC / g. in the balanced feed the fungi decreased from 9050.00UFC / g to 400.00UFC / 9; the bromatological composition of the feed was steady. Finally the alevin production increased by 140%; a maximum monthly production was reached of up to 65450 alevins. The development and application of the Good Practices of water Production improved the productivity of the fish factory Jacalurco, due to handling and physical and chemical and microbiological control of water and feed for the tilapias.
