The effects of water quality on growth of the reared Pacific white shrimp (Litopenaeus vannamei)

We investigated effects of water quality on growth of the Pacific white shrimp (Litopenaeus vannamei) reared in Heleh region of Bushehr in the south of Iran. Physico-chemical parameters such as water temperature, dissolved oxygen, salinity, pH and clarity were investigated in three 0.5ha shrimp ponds. Nutrients (nitrate, nitrite, ammonia and total phosphate), magnesium and sulphate as water quality factors were also investigated. Using one-way analysis of variance (ANOVA), a significant correlation (P0.05) while the afternoon pH values had negative significant correlation with the growth factors (P0.05).
