Monitoring of ecotoxicological parameters in the floating net cage area in Buluhcina Village, Kampar District, Riau Province, Indonesia

Abstract

Net cages culture activities produced organic pollutant that are distributed in the surrounding area and thus affects the water’s ecotoxicological parameters. This research was conducted along the Kampar River in the village of Buluhcina during the period of May to July 2023. Water samples were collected three times and the parameters measure were TSS, DO, COD, pH, Nitrite and Total P. Results indicate that in general, the water quality of the Kampar River’s was less contaminated (Pollution Index 1.19). The most polluted area was in Station 1 (PI 1.35) as indicated by high TSS and nitrite content that were more than the standard level. Relatively high nitrate content was also found in Station 3 (0.08 mg/l). In Station 2, however, the water quality was relatively good (PI 0.87), and the COD level was slightly above the standard value (0.5 mg/l). Based on data collected, it can be concluded that the water quality in the study site can be categorized as good and it may be used to conduct aquaculture activities.
