to maintain or increase genetic diversity and are consistent with guidelines for hatchery production of other native fish species.
                                                                                           * Genetic diversity of fingerlings should be maximized by crossing genetically diverse unrelated fish and maximizing broodstock fish combinations (e.g. using multiple males per female).
                                                                                           * Hatchery production of Macquarie perch is subject to a Health Management Plan, such as that defined in the NSW DPI "Hatchery Quality Assurance Program" (Rowland & Tully 2004).
                                                                                           * Large numbers of fingerlings are produced each year for stocking into wild waters, comparable with other successfully bred hatchery native fish, such as Murray cod, trout cod, golden perch and silver perch.
4b      Undertake a conservation stocking program for Macquarie perch.       1             * Sites known to have held the species previously, but where the species is now extinct, are stocked with fingerling Macquarie perch.

                                                                                             * Steps should be taken to improve habitat conditions in these areas.
                                                                                           * Sites within natural distribution and historically translocated populations established outside the natural distribution (Yarra and Mongarlowe rivers and Cataract Reservoir) known to have populations of the species are stocked with fingerling Macquarie perch, in a manner to promote genetic diversity.
                                                                                           * Self-sustaining populations are re-established at sites where the species has previously been extirpated from.
