Análisis de la implementación de la tecnología Biofloc y su efecto en la supervivencia de las larvas de camarón (Litopenaeus vannamei).

Abstract

The present work was carried out with the objective of analyzing the impact of Biofloc technology on the survival of Litopenaeus vannamei shrimp larvae in comparison with traditional culture systems. The biometric variables of: health, survival, larval growth rate and water quality were taken, through analysis of variance and Tukey test at 95% probability, as a result it was obtained that the growth rate in the bran treatment of rice was the lowest among the treatments with organisms of 8 mm in length and 2.08 grams in weight, this is due to high bacterial volumes that affected the health of the shrimp, a similarity was found between the treatment of molasses with yeast and the control treatment, with organisms that measured 10 mm in length, however in weight the molasses treatment obtained higher values among the treatments with organisms that weighed 2.26 grams. The control treatment for day 1 was effective, presenting a better response in repetition number 2, the molasses/yeast treatment on days 5,8,11 and 18 were effective, presenting a better response in repetition number 1 and 2 and The survival of the larvae was found in the control treatment with 93%, this is due to the fact that water exchanges and protocols were carried out, in comparison with the rice bran treatment, which obtained the highest rate. down 25%. Biofloc technology is presented as a promising alternative to improve the sustainability of crops, generating an investment of () that allows the implementation of Biofloc, which are microbial communities that improve water quality and larval nutrition, through an experimental design that compares Biofloc technology with traditional systems.
