Carrying Capacity of Kedungombo Reservoir for Net Cage Culture

Kedungombo reservoir with an area 4.800 Ha, being a drinking and municipal water supply, power generation, flood control, and fisheries activities namely net cage culture and capture fisheries. Carrying capacity assessment of Kedungombo Reservoir was conducted in relation to change in water volume and the present of net cage culture activity. This study to estimate carrying capacity of the reservoir for the culture of net cage. Carrying capacity was analyzed using the Beveridge formula (1996). Carrying capacity of Kedungombo Reservoir with net cage culture in this research is 5.114 tons/year with 1.461 total number of net cages allowed in reservoir. The number of net cages culture currently is 3.781 plots with total fish production on net cages culture is 13.233 tons/year. Thus, the culture activity of net cage fish has exceeded the carrying capacity of the Kedungombo Reservoir
