Fattening of the Cachamoto hybrid in Australian tanks with a water recirculation system (SRA)

Abstract

Fish farming has expanded in much of Venezuela through extensive methods in land lagoons. However, Water Recirculation Systems (SRA) are presented as a new form of production for the agricultural sector (Avnimelech, 2009); because they allow the use of water sources and land in those areas that, due to their low available flow and possible restrictions on the use of agricultural land, do not allow the development of an economically profitable aquaculture activity. Commercial crops with these production systems are scarce, almost non-existent, only those developed at the research level in the states of Zulia, Monagas, Lara and Bolívar are known, therefore, it is necessary to venture into this field and thus be able to increase production volumes in areas with restrictions for traditional crops. For these reasons, in the present work the weight gain was evaluated in specimens of hybrid fish cachama x morocoto (cachamoto) cultured in an Australian tank at low stocking density and with recirculation of water.
