Análisis reproductivo en hembras de camarón blanco Litopenaeus vannamei mediante uso de dos tipos de dieta, en laboratorio camaronero CBAS en Manta, Manabí.

Abstract

In the following research, the reproductive factors of female white shrimp Litopenaeus vannamei were evaluated, where the main objective was the comparison of two types of food, tested in the field in two pools in the city of Manta, province of Manabí, to determine the highest productivity in shrimp pools, through the use of these two diets. Where it was determined which of the food diets under study allowed to obtain better results in terms of production, egg count and cost benefit in acquisition. Using balanced food in the first pool and natural food in the second. Taking as predisposing factors the weight, size, age per lot and temperature of the pools in correlation to the food offered. Giving as results, raising the statistics by method of correlation, a remarkable significance to the greater production of nauplii in the pool with natural food squid and clam compared to the pool with balanced feed Mackey Marine Shrimp Flake Black, over a period of samples of five days for four weeks. Obtaining within the food analysis, in the shrimp of the pool # 1 offering balanced feed, a daily increase of 3.47% in the count of nauplii; However, in pool #2 using natural food, there was a daily increase of 0.86%, but yielding better weights, sizes and greater amounts in the eggs count.
