UJI PLAGIASI : Effect of Coal Particles on Embryonic Development, Egg Hatching Rate and Larvae Survival Rate of Climbing Perch Fish Anabas testudineus BLOCH

Abstract

This study aimed to analyze the impact of coal particles on the embryo development, egg hatching rate and larvae survival rate of climbing perch fish Anabas testudineus Bloch. The research was done in the wet laboratory of the Faculty of Fisheries and Marine, Lambung Mangkurat University for six months. The treatment in this study was a dose of coal particles exposure to eggs and larvae. The coal particles measuring 150 μm can penetrate the eggshell and interfere with embryo development at the stage of organ formation (organogenesis) and larval development. The eggs were exposed to coal particles 15 mg/litre of water. It turns hatching rate was 87% lower than without exposure to 98%. Similarly, the larvae survival rate (up to day 4) were exposed to coal dust 80% and without exposure to 93%.
