Intensive culture system of Litopenaeus vannamei in commercial ponds with zero water exchange and addition of molasses and probiotics

A 16-week trial was carried out to evaluate an intensive culture system of Litopenaeus vannamei in commercial ponds with zero water exchange. Two management strategies were used: one with the addition of molasses (ML) and the second with commercial probiotic and molasses (PML), each with four replic...

Two management strategies were used: one with the addition of molasses (ML) and the second with commercial probiotic and molasses (PML), each with four replicates.

The commercial probiotics used with molasses was a mixture of Bacillus spp. and Lactobacillus sp.
