Acondicionamiento y puesta en marcha de tanques zamoranos para la pre-cría de organismos acuícolas en la escuela de acuicultura y pesquería, Universidad Técnica de Manabí, extensión Sucre

Abstract

A technical project was carried out for the conditioning and commissioning of Zamorano tanks for the pre-breeding of aquaculture organisms in the School of Aquaculture and Fisheries, Technical University of Manabí, extension Sucre, in the period from November 2017 to January 2018. Zamorano tanks were created for the purpose of storing the water resource, since a few years ago they have been seen as an alternative to incorporate the development of fish production due to the ease of construction and lower cost that they represent compared to fish ponds geomembrane. Thanks to its circular shape, it helps the constant movement of water inside, which allows to stabilize physical chemical parameters of the water, improving the environmental conditions of the pond, and also facilitates the uniform distribution of the fish. Zamorano tanks are located in an area of 36 m2

, each 3 m in diameter, with a height of 1.20 m and 1 m of water level. The total water storage capacity is 8482 liters, while the total water in production use is 7068.6 liters (7 m3 ). The ponds are designed to culture aquaculture species, especially in the pre-breeding phase, (for example in the cultivation of red tilapia with a planting capacity of 300 organisms per cubic meter). The costs of materials and services used during the implementation and conditioning of the Zamorano tanks for the pre-breeding phase were determined, giving an initial investment value of $ $2.468,35 dollars for the construction, adaptation and start-up of the Zamorano tanks. The implementation and adaptation of artisanal Zamorano tanks will contribute to the acquisition of technical knowledge aimed at students of the School of Aquaculture and Fisheries of the Technical University of Manabí extension Sucre.
