Abstract

Floodplain swamp water commonly has low pH about 3-4 that became one of problems in aquaculture, mainly for catfish culture which requires neutral pH condition of pH 6.6-8.5. Liming is one of the efforts to increase the pH of water. The cockle blood shells contains of 61.16% CaO and 21.65 % MgO therefore it can be used as an alternative material for liming of fish pond. The aims of this research was to determine the best dosage of lime derived from cockle blood shells for improvement water pH, as well as the survival and growth of catfish. This research used completely randomized design with 5 treatments and 3 replications. The treatments were the dose of lime cockle shells (P1 1,000; P2 2,000; P3 3,000; P4 4,000; P5 5,000 kg/ha equivalent CaO). The result showed that P4 was the best treatment that has pH value i.e. pH of soil 7.0 and pH of water 7.3, survival rate 100%, absolute growth of length 3.34 cm and weight 7.65 g and feed efficiency 113.83%.
