Abstract

Regarding to the role of shrimp culture on economy of southern region of Iran, investigation of disease agents seems to be very important.
In this study the effects of stocking density of P. indicus (4 treatments) on health indices of pond in semi-intensive system was investigated.
The investigated health indices were: bacterial, fungal and parasites agents. The obtained data from this study indicated that the vibrio spp., Aspergillus sp. and Epistylis sp. had the highest contamination rate of the pond. ANOVA showed significant difference between the increase of bacterial and parasitical contaminations respect to stocking density (p<0.05). These differences are not significant among the ponds because the health indices were same for all of them (p>0.05). The liner regression showed relationship between the increase of bacterial and parasitical contaminations respect to stocking density. Also results showed that increasing of the shrimp density caused increase in all pathogen agents.
