Abstract
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.
Highlights
On Kedungombo reservoirs with an area of 4800 Ha, is a reservoir used for providers of raw drinking water, power generation, flood control, and fisheries activities namely net cage culture and fishing catch
Potential of water Reservoirs on Kedungombo comes from Serang River and Uter River, puddle on Kedungombo Reservoir area covers three areas, namely Kabupaten Grobogan administration, Sragen and Boyolali District
After the construction of the reservoir completed on Kedungombo Reservoir, the waters used for net cage culture activities
Summary
On Kedungombo reservoirs with an area of 4800 Ha, is a reservoir used for providers of raw drinking water, power generation, flood control, and fisheries activities namely net cage culture and fishing catch. After the construction of the reservoir completed on Kedungombo Reservoir, the waters used for net cage culture activities. Fish cultivation activites at the Kedungombo Reservoir experienced quite rapid development. The year 2012, the number of net cage culture in the reservoir still 1.696 plots, but in July 2017, the number of compartments in net cages culture on Kedungombo Reservoirs has reached 3.781 plots of net cages [1]. Whereas the development of the net cage culture should always consider the quality and sustainability of the water reservoirs for the sustainability of the net cage culture
