Identification of zoothamnium in the shrimp culture farms (Bushehr Province -Helleh Region)
The present investigation was carried out in the Helleh shrimp culture farms (north-west of the Persian Gulf) to identify the infection of Green tiger shrimps (Penaeus semisulcatus) to protozoan of zoothamnium. During the culture period. 100 samples were collected from the ponds and then transferred to the laboratory for further observations. The results showed that all shrimps in different growth stages were infected to this parasite and with lengthening the culture period, the number of infectious shrimps were increased. Furthermore, it was recognized that exoskeleton part was more affected by parasite than the other body organs. Also, the gills were in the second degree of prevalence. It should be noted that zoothamnium spp. couldn't be assumed as a dangerous or important factor in infecting the shrimp ponds.
