Implementación de laboratorios de química y microbiología, en el marco del ensayo: aplicación de tecnología biofloc en el engorde de camarón marino Litopenaeus vannamei

Abstract

This project was conducted in the School of Engineering in Aquaculture and Fisheries Technical University of Manabí, based Sucre (Bahia de Caráquez), with the aim of adapting equipment and supplies chemistry lab and microbiology for the development of technology biofloc and evaluation of its biota in cultured Pacific white shrimp Litopenaeus vannamei. The cost of this project was $ 8,000 ($ 4,000 as a contribution to the purchase of materials for the implementation of the "experimental station shrimp farming L. vannamei technology biofloc" and $ 4000 in matching with supplies and laboratory equipment) money obtained through a grant of degree awarded by the University. An experimental shrimp farming technology biofloc developed to assess the microbiological composition in four treatments as bioassay conducted for 15 days in June 2016 in which the results showed four phases or stages of development biofloc: early, early added, branched and mature, whose microorganisms during all these phases included 11 taxa: Euplotes, Yeasts, Tetraselmis, Lepocincles, Navicula, Pleurosigma, Thalassiosira, Rotifera, vorticela, Gastrotija and Nematoda. In the first sample the most abundant were: Nematoda, Thalassiosira, vorticela, Lepocincles; in the second: Nematoda, vorticela and Thalassiosira; in the third, Nematoda, vorticela, Rotifera and Thalassiosira.
