Fortification of chitosan and mangrove flour as windu shrimp feed (Penaeusmonodon) against infection white spot syndrome virus

Abstract

Langsa is one of the largest Windu shrimp producing areas in ACEH that holds considerable potential in the cultivation of windu shrimp. But recently the production of tiger shrimp has deteriorated due to by various disease attacks that have caused shrimp deaths including White Spot Syndrome Virus. This disease is a crop failure disease with high levels of mordibity and mortality. Transmission of WSSV was very fast and led to a 100% death within 3-10 days since the clinical symptoms arose. Therefore, research is conducted to prevent and treat WSSV by using shrimp skin and mangrove flour as feed. Chitosan flour from shrimp skin waste has the potential to be used as feed. The aim of this study was to determine the effect of fortification of chitosan and mangrove flour as windu shrimp feed on physiological conditions of windu shrimp. Physiological observations carried out include feeding responses, swimming, body redness (body color changes), white spots on the carapace and counting shrimp that die during maintenance. Physiological observations carried out include feeding responses, swimming, body redness (body color changes), white spots on the carapace and counting shrimp that die during maintenance. Based on the results of the study show that the more mangrove flour and chitosan fortified in shrimp feed, the level of shrimp resistance to white spot syndrome virus infection is increasing which is characterized by a low mortality rate.
