Pencegahan Infeksi Virus White Spot Syndrome Virus (Wssv) Pada Udang Windu Penaeus Monodon Dengan Cairan Ekstrak Pohon Mangrove (Cepm) Avicennia Sp. Dan Sonneratia Sp.

Abstract

The quality and survival rate are still being the problem that hampers the productivity of black tiger shrimp, Penaeus monodon culture. Impaired quality of larval shrimp and environmental conditions can confer shrimp be infected by diseases, including viruses such as white spot syndrome virus (WSSV). Prevention of disease infection using chemicals can offer negative impacts on water, pathogen resistance and consumers. This study was conducted to examine the efficacy of an alternative prevention compound as liquid mangrove extract (CEPM) from Avicennia sp. and Sonneratia sp. By immersion in different dose of CEPM, i.e. 250, 500, 750 and 1000 ppm, the patogenicity of WSSV was found to be different. Patogenicity of WSSV decreased after treatment by CEPM, hence this could be used to induce shrimp immunity. Optimum dose of CEPM was 250 ppm, which could increased survival rate of shrimp after challenging by WSSV, up to 98.4% shrimp survived.
