DESIGN AND EVALUATION OF ONE PROTOTYPE OF FISH CULTURE SYSTEM IN SAN CLEMENTE DE TERAPA, MOCTEZUMA, SONORA

Abstract

This research will help to design a system of Oreochromis niloticus intensive fish farming in the community San Clemente de Térapa, Moctezuma, Sonora, México, using thermal water from a perennial spring in circular ponds during 12 weeks. Production of O. niloticus is a common practice in aquaculture to local consume, because this specie has an adequate growth rate and feed conversion, also resist critical environmental conditions like temperature, anoxia, and tolerance to water hardness and high organic matter content. This design was according to quality and quantity of water. Body growth and survive was measured, also the farming viability under the particular conditions of the prototype design. Two circular ponds of 4.5 m and 3 m in diameter were installed, where were introduced 800 and 400 masculinized “young fish”, whit an average weight of 0.84 and 0.54 g respectively. Biometrics measured and physicochemical parameters of water were assessment (temperature, dissolved oxygen and pH). At the end of the culture was obtained a survive rate of 98.5% and 98.25 % en each pond respectively, an excellent adaptation of the organisms and an acceptable body mass. This study shows is possible to get positive results under these conditions.
