ABSTRACT
The current study was carried out for 147 days to assess the pathogenic Vibrio count of Litopenaeus vannamei culture ponds and the influence of probiotics from Mophus Bander, Srikakulam District, Andhra Pradesh, India. Three ponds were selected; one is control and other two were experimental (Pond A and B). The physico-chemical parameters of the culture ponds were recorded by adopting standard methods. During summer crop the control ponds were harvested at 24.0 gm on 107th day for the year 2025 due to the incidence of Vibriosis disease. The Experimental ponds were harvested normally in summer season at 30.5 gm on 124th day & 31.0 gm on 127th day during 2025.
This study suggests that the probiotics TOTAL as pond probiotic & LACTOMAX as feed probiotic are the key agents which have a great impact on the reduction of total pathogenic Vibrio count in culture ponds of Litopenaeus vannamei.
Key words: Litopenaeus vannamei, Vibrio, Probiotics, sediment and temperature.
