Effect of water quality parameters on growth and survivability of mud crab (Scylla tranquebarica) in grow out culture at Kakinada coast, Andhra Pradesh


Author(s): Sandeep Pedapoli and Kurva Raghu Ramudu

Abstract: An experiment was carried out to study the effect of physico chemical properties of water such as Salinity, Temperature, pH, DO, Ammonia, Nitrate and Nitrite on growth and survivability of mud crab (Scylla tranquebarica) in grow out culture in a brackish water fish farm at Fisheries Research Station – Kakinada. The experiment has been started with pond preparation which includes drying, ploughing and culturing with excellent prebiotic and probiotic. Natural seed was purchased and stocked at no.200/0.5 acre pond and fortnight sampling has taken to see the survival and growth associated with the water quality parameters. The study notify that among the water quality parameters salinity plays very important role as it decreases to the 10.5 ppt while the survival rate has been dropped from 87 to 45 percentage. At the same time ADGR/g day-1 has been dropped from 2.68 g to 0.97 g when salinity decreased. In addition to that DO also affect survivability and growth, due to the slight changes in temperature. But the rate of survivability has been constant when salinity has maintained at range of 15 – 25 ppt. So, among the water quality parameters the salinity was limiting factor for determining the survivability and growth of the crablets in the grow out culture.
