| Abstract | ||
| Following introduction of (Litopenaeus vannamei) to shrimp culture industry by Iran Fisheries Organization, the post-larvae of this species were reared successfully in earthen ponds in Bushehr and Khuzestan (Choebdeh site) provinces. Due to activity of shrimp culture sites in Choebdeh and importance of input and output water quality, this study was carried out in 11 selected stations including: 2 stations in Bahmanshir River, 2 stations in C4 and C5 irrigation canals, 6 stations in active shrimp farms along C4 canal ,and C5 canal and one station in output drainage canal. About 66 samplings were carried out during May-October 2009 from stocking to harvesting phases. Physical and chemical parameters were sampled biweekly and some parameters such as pH and temperature were measured in-vivo by HACH equipment. Other parameters such as DO, salinity, BOD5,TSS, NO3, NO2, PO4 and turbidity were analyzed based on standard methods by expectrophotometer equipment in Lab. Maximum values were: DO=11.4ppm PO4 =3.93ppm NO3 =10.09ppm TSS= 5408ppm pH=8.4 NO2 =0.18ppm and BOD5 =10.4ppm. Majority of parameters except TSS, NO3 and PO4 were in the range of acceptable limits. There was no difference in quality of waters between internal water from river and drainage canals. | ||
