Desempenho do camarão Litopenaeus vannamei (Boone, 1931) em diferentes densidades de estocagem sem uso de alimentação artificial

Abstract

The density of stock of the shrimp Litopeneaus vannamei is one of the principal factors that determine the survival, the growth and, consequently, the final biomassa produced in a cultivation. In this form, this work had how I aim to value the zootechnic performance of the Litopennaeus vannamei at different densities of stock without use of artificial food. The experiment was carried out in the technological Centre of the Aquicultura – CTA located in the local authority of Extremoz-RN, during the period of September the December of 2015. For the experiment an experimental delineation was employed completely casualizado, constituted of two treatments and three simultaneous repetitions. The treatment T1, density of 3 shrimps for m², and treatment T2, density of 6 shrimps for m². The bone-meal was used in this experiment looking for a bigger biological productivity. For statistical analysis, the data of the zootechnic parameters of the shrimp were subjected to the analysis of variância (ANOVA). The biomass gain results, WITH average T1 and T2 13.3 g 10.3 g Were obtained with 3:06 shrimp BY m ², respectively, there plows first and second experiments, NOT Being the Significant Differences. Increasing the storage density you it Litopeneaus vannamei affects the Growth and Increased cultivation Survival density, but with hmm Increased number of individuals without settlement, T2, Out More viable economically.
