ABSTRACT

This study examined the effects of UV and formalin treatment on the survival of Penaeus monodon larvae and bacteria communities in the rearing tanks. The survival of P. monodon in the 36 h experimental period was not significantly affected by the water pretreatment (P > 0.05). However, the bacteria communities were significantly affected by water pretreatment (P < 0.05). Heterotrophic bacteria and vibro counts in the formalin treatment were significantly lower than UV treatment and untreated group (P < 0.05). Based on the results obtained in the present study, we suggest that formalin treatment could be a better away to control bacteria in P. monodon larvae culture.
