A review of the health status and diseases of cultured Penaeus indicus in Sistan-o-Baluchistan Province, Iran
The health status and diseases of Penaeus indicus in Sistan-o-Baluchistan culture ponds of Guater Site were assessed during the year 2005. Over the shrimp culture period, two ponds were selected from two farms, and 19 shrimp specimens were caught randomly each month from each pond. The specimens were immediately transferred to lab for further investigation. After recording abnormal signs including color change of cuticle and gills, presence of white or black spots on the body, the specimens were studied for bacterial, fungal and parasitic infections. Bacterial infections included Citobacter, Pseudomonas, Aeromonas, Actinobacter, Proteus, Vibrio alginolyticus, V. harveyi, V. parahaemolyticus, V. spelendidus and Vibrio sp. Fungal infections of the cultured P. indicus included Fuzarium spp., Mucor, Cladosporium, Aspergillus spp., Penicllinium spp., sterilized hyphae and yeast. The parasites found included Zoothamnium, Epistylis, andVorticella. Since the second month of shrimp culture onwards around 10-65% of shrimps showed white and opaque spots on abdominal muscle which started from the sixth segment. Sometimes, the dots covered the whole abdomen, giving the shrimps a cooked look and a yellowish watery sac on hepatopancreas under the carapace of the specimens could be observed. There was no evidence of disease agents based on microbial, parasitic and environmental studies. The food which was used for shrimp culture was analyzed and showed anion and cation imbalance. Our results showed Idiopathic Muscle Necrosis Syndrome (IMNS) and Subcarapace Watery Sac Syndrome (SWSS) sings in the cultured shrimps.
