Abstract

Lime is composed of different particle sizes. This research aimed to determine the optimal particle-size distribution of mussel freshwater shell lime to increase the pH of swamp water and to assess its effect on the survival and growth of catfish. This research used a completely randomized design with six treatments and three replications. The treatment consist of calcite lime as a control with a percentage of retained lime at sieve 10 mesh 20.7%, 20 mesh 22.7%, 60 mesh 55.3%, and passed 60 mesh 1.3% (P0), mussel freshwater shells lime with retained on 10 mesh 40%, 20 mesh 20%, 60 mesh 20%, and passed 60 mesh 20% (P1), retained on 10 mesh 20%, 20 mesh 40%, 60 mesh 20%, and passed 60 mesh 20% (P2), retained on 10 mesh 20%, 20 mesh 20%, 60 mesh 40%, and passed 60 mesh 20% (P3), retained on 10 mesh 20%, 20 mesh 20%, 60 mesh 20%, and passed 60 mesh 40% (P4), retained on 10 mesh 20.7%, 20 mesh 22.7%, 60 mesh 55.3%, and passed 60 mesh 1.3% (P5). The results showed that the application of mussel freshwater shells lime with particle size percentages retained on 10 mesh 20%, retained on 20 mesh 20%, retained on 60 mesh 20%, passed 60 mesh 40% (P4) was the best treatment that can increase the swamp water pH from 5.11 to 7.60, absolute growth of weight and length of 7.86 g and 5.56 cm, respectively, and survival rate 96.33%.
