Description:
Decline in capture fisheries and sea food demand lead to improve shrimp aquaculture activities. Iran had good
experiences on shrimp farming during tow decades. White spot disease collapse the shrimp farming activities in
recent years. Although goater were the main site for shrimp culture but this site were affected by white spot
disease (WSD). Environmental stressors were the main criteria for attention in this regard. An investigation was
carried out to monitor management practices and to find out whether there is any relationship with occurrence of
white spot disease and environmental parameters. Five semi-intensive shrimp farms were selected in bahookalat
chabahar area (2500 ha). The farms were situated at goater area. Tree ponds from each farm at random were
selected for the study. All major environmental parameters such as O2, temperature, salinity. PH, nitrogen were
recognized by standard method. Logistic regression were used for relationship of water parameters with
occurrence of white spot disease. There were no significant relationship between PH, salinity and nitrogen in
ponds and canals. But significant variations were recorded for oxygen (1.58) Temperature (0.89) with occurrence
of white spot disease. Pond aeration can use for reduction and prevention of diseases.
