3e      Research best practice for habitat restoration.                                                                                      2             * Improve the resilience of the species by increasing refugia available, measured by increased abundance/biomass.

4a      Refine and improve captive breeding techniques for Macquarie perch.  1             * Hatchery production of fingerlings is able to operate with broodstock periodically sourced from the wild, yet maintained for multiple breeding events in captivity, rather than capturing spawning run individuals each year from the wild.
