Monitoring Status Daya Dukung Perairan Waduk Wadaslintang Bagi Budidaya Keramba Jaring Apung Monitoring of Carrying Capacity Status of Wadaslintang Reservoir on Cage Net )

Carrying capacity of waters is defined by physical condition such as quantity and quality of the waters. Physical condition alteration from time to time can cause alteration of the carrying capacity status. Monitoring of carrying capacity of Wadaslintang Resevoir was conducted in relation to change in water volume and the present of cage net activity. Carrying capacity of waters can be calculated based on P content one of the limiting factors of waters productivity. The research was conducted using survei method in five stations during dry (May 2008) and wet (November 2008) seasons, each season with three times sampling against parameters for cage net suitability. Carrying capacity was analyzed using the Beveridge formula (1996) which indicate the permissible productivity of the net cage. The result of this research showed that physical condition of Wadaslintang Reservoir can support the cage net activity. The present cage net activity is still appropiate with the carrying capacity and the production is potentially to be increased with 87tons/harvest
