Abstract

Water pollution caused by human anthropogenic activities has deteriorating effect on water quality for aquaculture. Therefore, the objectives of this research were to determine how water quality, population and shrimp genetic characteristic in polluted area. Especially in East Java which have high virulency on WSSV outbreaks.Data exploration using surveillance technique was collecting physical and chemical water quality parameters. Shrimp samples were analyzed for morphological and genetical characteristics using specific WSSV primer ICP 11.Water quality at all sampling locations were categorized as polluted refers to ammonia and TOM  concentrations. Low water quality acts as a trigger for WSSV outbreaks. Shrimp pond from Situbondo exhibited as carrier indicated by the presence of WSS infection based on genetic characteristics, while morphological characteristics did not.

Abstract

Tilapia growth in pond using polyculture system is higher than tilapia cultured in monoculture system. Employing water column for fish and prawn culture to obtained higher production yield. This research using experimental descriptional method and data were analyzed using independent t-test, comparing monoculture and polyculture of Tilapia growth performance. Specific growth rate of polyculture Tilapia at 4.46%/BW/day is higher than monoculture fish at 4.80%/BW/day. FCR comparison  were 1,1 and 1.17 for polyculture and monoculture respectively. Water quality treatments were at optimal range for Tilapia growth at 26-30C; 7,34-8,36; and 5,3-8,8  ppm for temperature, pH dan dissolved oxygen, respectively.
