Utilization of Golden Apple Snail (Pomacea canaliculata) Shells as Liming Materials for Pangasius sp Culture in Swamp Fish Pond

Liming ponds is intended to increase swamp soil and water fish ponds pH.The golden apple snail (Pomacea canalicuata) is one kinds of agriculture pest which is potentially used as material of lime.The golden apple snail shells containing CaO (91.62%) and MgO (1.66%).

This study aims to determine the best dosage of lime derived from golden apple snail shells to increase the pH of soil and water, as well as the survival and growth rate of catfish fingerlings.This study used Completely Randomized Design (CRD) with Right Link 5 treatments (4 treatments of different dosage of lime derived from golden apple snails and 1 treatment using calcite and 3 replications.The treatments used consisted of different dosages of lime : P1) 4 ton/ha; P2) 5 ton/ha; P3) 6 ton/ha; P4) 7 ton/ha and P5) calcite 6 ton/ha equivalent to CaO.The result showed that maximal pH value of P4 (lime derived from P.canaliculata 7 ton/ha) is almost Enamel Oven Tray same as pH of P5 (calcite 6 ton/ha) but P4 is faster to reach than that of P5.

At the final day of research P4 has no significant different with calcite 6 ton/ha (P5) for alkalinity, fish growth and feed efficiency.
