Threats [top]

Major Threat(s): Gill nets and the use of outboard motors have been introduced on the lake since the 1980s. Adamson's grunter is one of the largest fish species in the lake and therefore has become one of the main targets of net fishermen. Oil drilling and logging have also developed in the area over the past ten years.
