Kandungan Logam Berat Pb Dan Cd Pada Ikan Gurame (Osphronemus Gouramy) Dan Toman (Channa Micropeltes) Di Waduk Plta Koto Panjang, Provinsi Riau
Osphronemus gouramy and Channa micropeltes inhabit the the Koto
Panjang Dam, Riau. The presence of anthropogenic activities may produce heavy
metal that enter the water and thus accumulate in the organisms living in that area.
A study aims to understand the heavy metal content in gill, muscle and kidney of
O. gouramy and C. micropeltes living in that dam, as well as in the water and in
the sediment has been conducted in April 2019. Samplings were conducted 2
times, once/ 2 weeks. Results shown that the heavy metal content in O. gouramy
were as follows: Pb 0.0873 mg/kg and Cd 0.0426 mg/kg (gill), Pb 0.0684 mg/kg
and Cd 0.0394 mg/kg (kidney), Pb 0.0376 mg/kg and Cd 0.0219 mg/kg (muscle).
Water quality parameters were as follows: pH 6-6.7, temperature 28-33°C,
DO5.42-7.14, brightness 1.5-2.5 m and depth 22-55 m. Based on data obtained, it
can be concluded that the heavy metals content in fish, in the water and sediment
were relatively low.
Key words: Koto Panjang Reservoir, heavy metal, goramy fish
