Abstract

Aquaculture is one of the fastest rising sectors in the world today. An Aquaculture system is diversified as fresh, brackish and marine water culture systems. The growth of aquaculture as an industry has accelerated over the past decades, this has resulted in environmental damages and low productivity of various crops. The need for increased disease resistance, growth of aquatic organisms, and feed efficiency has brought about the use of probiotics in aquaculture practices. The first application of probiotics occurred in 1986, to less their ability to increase growth of hydrobionts (organisms that live in water). Probiotics were used to improve water quality and control of bacterial infections. Now a day there is documented evidence that probiotics can improve the digestibility of nutrients, increase tolerance to stress, and encourage reproduction. Currently, there are commercial probiotic products prepared from various bacterial species such as Bacillus sp., Lactobacillus sp., Enterococcus sp., Carnobacterium sp., and the yeast Saccharomyces cerevisiae among others, and their use is regulated by careful management recommendations. The present paper shows the current knowledge of the use of probiotics in aquaculture, its antecedents, and safety measures to be carried out and discusses the prospects for the study in this field.
