Got the hatchlings, now for the habitat

Got the hatchlings, now for the habitat

The endangered Macquarie perch have been bred for the first time in
captivity. Using a novel approach involving the construction of an
eartificial streamf scientists at the Narrandera Fisheries Centre led captive
perch into thinking they were in a natural environment and the fish
reached breeding condition. Dr Dean Gilligan from I&I NSW said the fish
used for the successful breeding program were from a remnant
population rescued from the upper Lachlan catchment after their habitat
was threatened by the recent introduction of redfin perch. Macquarie
perch populations began to crash in the mid 1900s, most likely due to
habitat degradation associated with river regulation, fish passage barriers,
land clearing and associated sedimentation and other forms of water
pollution. By the 1970s, Macquarie perch were considered to be seriously threatened with extinction and the
species has continued to decline. With this breakthrough, I&I NSW will look at using a conservation stocking
program in those parts of the Murray]Darling Basin where Macquarie perch populations are diminished or
have become locally extinct provided suitable habitat can be found or rehabilitated. This research has been
supported with funds from the Recreational Freshwater Fishing Trust. For more information see:
