Producción de biomasa del crustáceo artemia franciscana (kellogg, 1906) alimentadas con dietas a base de diatomeas y chlorophytas.

Abstract

The Artemia sp has acquired great importance as the main source of food for aquatic species of commercial value because it is eased to ingest, its excellent digestion capacity and the high nutritional value. The objective of this work is to cultivate the Artemia until the adult stage and to use them as food in shrimp broodstock. Therefore, it is essential to provide adequate conditions during the cultivation of Artemia to ensure the nutritional value and biomass. To evaluate the effect of different phytoplankton diets on the biomass production of Artemia franciscana, three different diets based on microalgae (100% Tetraselmis sp., 100% Thalassiosira sp. and 50% Tetraselmis sp – 50% Thalassiosira sp.) were provided. The biomass was measured in relation to growth, survival, and weight at harvest. The statistical analysis of variance p>0.05 for the diets provided determined that there was no significant difference between the different treatments. The higher growth rate with a mean of 5.38 mm was obtained with the diet based on Thalassiosira sp. The diet with Tetraselmis sp. resulted in around 95.47% of survival rate. The mixed diet provided a biomass of 1.16 grams in dry weight, which was the highest compared to other treatments.
