Evaluación del crecimiento y supervivencia de camarón blanco (litopenaeus vannamei) cultivados a diferentes salinidades y densidades de siembra

Abstract

It is essential for the sustainability of the Ecuadorian shrimp industry in accordance with respect for the environment, the reduction or efficient use of the areas used in the cultivation of Pacific white shrimp, there are two methods, the first is to improve the FCA and the second is to intensify production in ponds. For this reason, many farms are redistributing their cultivation areas and building nursery channels and ponds to shorten the fattening time and achieve more production cycles per year. The present work aims to evaluate the growth and survival of white shrimp Litopenaeus vannamei grown in captivity at different salinities and stocking densities, as well as to control the physicochemical parameters of water quality during culture time in order to optimize their management in super-intensive culture in a system with symbiotic technology. A completely randomized factorial experiment was applied, with two treatments for each study factor: salinity (2 and 5 UPS) and planting density (20 and 60 cam/tq), 12 experimental units were used (270 l plastic tanks) to equalize the study salinities, fresh water was obtained from a well located in the municipality of El Guabo (0 UPS) and salt water from Puerto Bolivar (35 UPS), as for the planting density ratio (100 cam/m2 and 300 cam/m2) was established with the bottom area of the tanks 0.20m2.
