Lake Eacham Rainbow Fish, Melanotaenia eachamensis
Problem:
The Lake Eacham
Rainbow Fish had disappeared from Lake Eacham by 1985. Its disappearance has
been attributed to the predatory and competitive effects of four introduced
native fish species – the Mouth Almighty (in particular), the Archerfish, the
Banded Grunter and the Bony Bream. All were introduced into Lake Eacham between
1983 and 1987.
Background Information:
Early research by the
Queensland Museum and the Department of Primary Industries drew attention to the
extinction in Lake Eacham. Recent biochemical research by the University of
Queensland has re-established the fact that this fish is a distinct species.
Recent studies by the University have located the species in nearby Lake
Euramoo, Dirran Creek and the upper reaches of the South Johnson
River.
Solution:
Educate the public
about the risks of moving fish from one area to another (translocation).
Continue maintaining captive breeding populations. Manage recently discovered
populations.
The next species is the Honey Blue-eye
