Evaluación del uso de un alimento balanceado con un tamaño de partícula de 0.5 mm durante los primeros 7 días en la fase de precría del camarón blanco Litopenaeus vannamei en una camaronera ubicada en el sector Los Farallones, Isla Puná.

Abstract

In Ecuador, the first shrimp production pools were built in the coastal area since it has the best climatic conditions in the country. Thanks to this, aquaculture in Latin America and especially in Ecuador has been one of the activities with the highest productive growth and economy during the last 15 years, managing to position itself today in second place in the table of the main export products of Ecuador. During the months of April and May of the year 2022, the following investigation was carried out in a shrimp farm located in the Los Farallones sector, Puná Island. The objective of the work was to evaluate the effect of a balanced feed with a particle size of 0.5 mm during the first 7 days of pre-breeding, as main variables studied weekly weight, survival percentage and coefficient of variation; Student's t-statistic test was used. For the management of the trial, 4 daily feeding doses divided in equal parts will be applied; T1 for the first 7 days, 0.5 mm was supplied and then the BF was changed to 0.8 mm, TT 0.8 mm BF was applied from the first day. In both treatments on day 16 the BF of 1.2 mm was produced. As a result, minimal differences were obtained in weekly growth in T1, in addition to the fact that its survival percentage was higher, however, in TT a lower coefficient of variation was increased.
