    Acondicionamiento y puesta en marcha de una estación experimental para el engorde de camarón Litopenaeus vannamei con diferentes niveles de proteína del alimento balanceado y tecnología de biofloc
    (Universidad Técnica de Manabí, 2016) Andrade Arteaga, Andrés ; López Vera, Juan José ; Álvarez Capote, Susana
    This project was carried approximately 8 months. It consisted of the preparation and implementation of the Experimental Station of Litopenaeus vannamei shrimp farming with Biofloc Technology. It with a roof for obtaining Biofloc a large scale (macrocosm), with a circular fiberglass 3000 L capacity with aeration continues and an area of Microcosm with 12 plastic circular tanks 300 L capacity tank area, aerated through connections plastic air stones and air, connected to a central blower 24 h. The first stage contemplated support in the construction of the station, then the equipment and conditioning thereof with team multiparameter YSI, reagents and food primarily, as well as participation in training biofloc in the macrocosm and the implementation of microcosm area, with the development of bioassay fattening juvenile shrimp Litopenaeus vannamei for 15 days to check the functionality of the station. We worked with the 12 experimental tanks were tested four triplicates treatments and productive response of the species to be fed pellets of different protein levels and the presence of flocs food, made by technology biofloc was assessed. The control treatment (TC) without balanced food (AB), T1 with AB 35% crude protein (CP), T2 with AB 28% CP and T3 with AB 22% CP. In each experimental tank they were prepared microcosm 200 L, 150 L initially with seawater filtered pretreated and 50 L biofloc from the macrocosm. 12 youth in each approximately 1 g of initial weight were placed. Environmental parameters (temperature, dissolved oxygen, salinity and pH) were monitored daily in the morning and afternoon. The results indicated the outstanding participation of biofloc growth, biomass, FCA, good environmental conditions, health status of animals and the functionality of the Experimental Station. It is concluded that the practice of Biofloc technology deserves to be studied in depth, as an alternative that would achieve more productive and profitable aquaculture crops.
