Investigating the effects of physico-chemical properties of water on growth and survival rate of the cultured Penaeus semisulcatus
Studying the likely relationships between biotic and abiotic factors and their effects on growth and survival of the cultured aquatics is one of the most important fishery research areas. In this study, we used three Penaeus semisulcatus culture ponds, each with 0.4 hectares surface area and a stocking rate of 25 shrimps per square meter in Bushehr Province of Iran to examine the effects of physico-chemical properties of water on growth and survival rate of the shrimp. The average body weight of the shrimp reached as high as 10.59 grams and with an estimated food conversion ratio of 1.3, a mean yield of 1954 kg/ha was recorded in this study. The independent variables including water temperature, pH, planktonic bloom, salinity, nitrate and phosphate, water depth, dissolved oxygen and food consumption had all significant correlations with the shrimp weight as dependent variable. The planktonic bloom showed the highest correlation with the shrimp weight (r=0.8.7). The overall correlation of first four most important factors with the shrimp weight, namely planktonic bloom, morning dissolved oxygen, pH stability and feeding rate was estimated to be r=0.939.
