A study was carried out to analyse the bacterial abundance in the brackishwater culture ponds of Penaeus monodon situated along coastal Andhra Pradesh (India). The physico-chemical characteristics of the pond water and the bacterial counts of pond water, pond sediment and muscle and hepatopancreas (HP) of the shrimps were estimated at intervals of 15 days for one crop cycle during 1996. The physico-chemical characteristics of the pond water in all the ponds were within normal limits. The semi-intensive ponds recorded higher bacterial loads as compared to modified-extensive ponds. In pond water, the bacterial loads fluctuated erratically, and showed no definite trend with the progress of culture period. The pond sediment with its high organic load recorded higher values than pond water and demonstrated a general trend of increase of bacterial load with the progress of the culture. The bacterial load in HP of shrimp was found to be higher than that in muscle and both showed an increasing trend with shrimp age but the overall load remained within the safe level. The high bacterial loads noted in semi-intensive ponds prior to crop harvest are found to be associated with poor water quality, exaggerated by low D.O. , high ammonia, algal blooms and high organic content in the bottom. Relationship could not be found between water quality parameters and the bacterial load in the pond water and also there was no relationship between the bacterial load of shrimp and that of the pond environment. |
