Qualitative and quantitative analyses of the phytoplankton were examined along with physico-chemical parameters in the ponds treated with microbial agents and in the untreated ponds without microbial agents. A total of 18 well-diversified species of phytoplankton belonging to Bacillariophyta, Dinoflagellata, Cyanophyta and Chlorophyta were investigated during the study period. The average phytoplankton abundance in the treated ponds (6.08×105cellsL−1 in HJW ponds and 7.11×105cellsL−1 in JK27 ponds) was significantly less than that in the control ponds (1.27×106cellsL−1, P<0.05). The dominant group in both the treated ponds was Bacillariophyta (70.84% in HJW and 64.36% in JK27), whereas the dominant group in the control ponds was Cyanobacteria (37.05%). The analysis showed that the addition of probiotics significantly increased (P<0.05) the concentration of Coscinodiscus species from Bacillariophyta in the treated ponds (HJW and JK27) and significantly decreased (P<0.05) the concentration of Oscillatoria species compared with the control ponds. None of the water quality parameter results differed significantly between the treatments (P>0.05). The findings of the present study suggest that the application of commercial probiotics in shrimp farms could positively influence the growth of beneficial algae, such as Bacillariophyta rather than harmful algae, such as Cyanobacteria, and thus improves the water quality, the health of the shrimp and increases production.
