Effect of the presence of flocs on growth in juvenile Pacific white shrimp litopenaeus vannamei in intensive systems under experimental conditions

Abstract

To determine the effect of the floc on the growth of juvenile shrimp Litopenaeus vannamei in intensive systems under experimental conditions. Materials and methods. To determine which treatment reached the highest, physical and chemical factors were measured: dissolved oxygen and temperature; and population parameters Accumulated Growth, Survival and Feed Conversion Factor. Collecting these data for 25 days where the Litopenaeus vannamei shrimp had an initial weight of 1.8 gr in both treatments. Results. According to the results obtained in the experiment, the commercial feed + floc treatment obtained a final growth of 5.35, on the other hand, the treatment with only commercial feed reached 4.9 gr. Conclution. The commercial feed + floc treatment gained larger size and biomass in less time because the floc application managed to provide more nutrients to the applied diet and in this way the shrimp took advantage of this supply, this natural food being the primary food source. while in the treatment without floc, lower biomass was obtained since no substitute was added to this treatment, only commercial feed, when performing the statistical analyzes it was found that p<0.05, which indicates that there was a significant difference, substantiating that with the use of floc growth of shrimp Litopenaeus vannamei is higher.
