Once again, another wave of mysterious fish deaths in Sarawak – around Bakun, Mukah, Kapit, Marudi and in the Baram River near Miri. The worst hit is reportedly the Balui River around the jinxed Bakun Dam.
In Baram, the affected fish species include ikan baung, ikan burih, ikan tapah and ikan padi as well as various types of prawn. Sarawak NGO Brimas observed that “most of the fish seemed weak, tired and have difficulty breathing. As a result, the fish surfaced for air but after some time suffocated to death. Also, the fish appeared blind.”
Brimas found that the gills of the fishes were not clogged with mud or blocked by silt. No mud was found within the stomach or intestines of the dead fish, but the insides seemed watery. The river was described as “brownish, muddy and polluted with silt due to logging, oil palm plantations and industrial development activities.”
