STATUS TROFIK DAN DAYA TAMPUNG BEBAN PENCEMARAN AIR LIMBAH BUDIDAYA IKAN KJA DI WADUK KOTO PANJANG

Abstract

The aims of this research are to identify water quality concerning to chemical-physical
and biological aspects and the present trophic condition of Koto Panjang Reservoir and
its pollution load carrying capacity to support freshwater floating net cage
aquacultureand total phosphate concentration to determine load carrying capacity.
These ranges of values showed that this area is classifed as an eutroph to hypereutroph
waters. Pollution load carrying capacity of the Koto Panjang reservoir when the annual
productivity is estimated as high as 2.186 ton/year. The conclusion of this research is
optimum number of floating net cage that can operated in research location are 182
unit.

Keywords: pollution, aquaculture, capacity.
