(For this reason, the species has proven difficult to breed artificially, as captive females do not produce ripe eggs when kept in still broodponds or tanks). Macquarie perch breed in late spring at temperatures of 15 to 16 °C, in flowing water over unsilted cobble and gravel substrate. The demersal (sinking) eggs fall into the interstices (spaces) between the gravel and cobble, where they lodge and are then protected and incubated until hatching. This is a breeding strategy similar to that used by introduced species of <a href="/wiki/Trout" title="Trout">trout</a>. </p><p>Macquarie perch appear to have inherited the sexual dimorphism of other <i>Macquaria</i> species where females reach a larger maximum size than males. Females also reach sexual maturity at older, larger sizes than males. </p><p>Limited ageing work on Macquarie perch has recorded fish to 20 years of age.

(Having said this, the <i>primarily</i> <a href="/wiki/Lowland_(freshwater_ecology)" class="mw-redirect" title="Lowland (freshwater ecology)">lowland</a> golden perch, being highly adaptable species, did extend into <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> habitats) in some situations. </p><p>Macquarie perch are found in the eastern coastal Shoalhaven and Hawkesbury-Nepean river systems as well as the Murray-Darling Basin, indicating that, as with some other native fish genera in south-eastern Australia, Macquarie perch have managed to cross the Great Dividing Range through natural river capture/connection events. Genetic research now indicates the Shoalhaven River population was the ancestral Macquarie perch population and colonised the Hawkesbury-Nepean system ~2 million years ago, and the Hawkesbury-Nepean population then colonised the Murray-Darling Basin – possibly through a "wet divide" in the Breadalbane Plains region, ~657,000 years ago (Faulks et al., 2008). </p><p>Major differences between the eastern coastal populations and the Murray-Darling population are that the eastern coastal populations display a far smaller average and maximum size (15 and 20 cm respectively) and are reported to have one less vertebra than the Murray-Darling species. Recent evidence suggest the Shoalhaven population is now extinct after a rapid decline due to damming of their habitat and subsequent encroachment of legally and illegally stocked fish species. The Hawkesbury-Nepean population appears to be threatened by introduced trout and other exotic fish, river damming and regulation, siltation, and urban encroachment, but does not appear to be as threatened as the Murray-Darling species. Information on this page relates primarily to the Murray-Darling population. </p><p>There is a <a href="/wiki/Species_translocation" title="Species translocation">translocated population</a> in the <a href="/wiki/Mongarlowe_River" title="Mongarlowe River">Mongarlowe River</a>, a tributary of the Shoalhaven.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-:0_5-0" class="reference"><a href="#cite_note-:0-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> It is thought that this population descends from fish from the Murray-Darling Basin and not the eastern sub-species native to other parts of the Shoalhaven catchment.

Gross overfishing by anglers, habitat degradation through siltation, and regulation of flow and "thermal pollution" by dams have all been major causes of decline. A mysterious but endemic disease called Epizootic Haemotopoeitic Necrosis virus (EHN virus), now vectored by introduced <a href="/wiki/Perch" title="Perch">redfin perch</a>, has been proven to be fatal to Macquarie perch, and may have contributed to the decline of some populations of Macquarie perch in <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> impoundments. What has become clear however is that total domination of the Macquarie perch's <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> habitats by introduced <a href="/wiki/Brown_trout" title="Brown trout">brown trout</a> (<i>Salmo trutta</i>) and <a href="/wiki/Rainbow_trout" title="Rainbow trout">rainbow trout</a> (<i>Oncorhynchus mykiss</i>) have also been a major cause of decline. Indeed, Macquarie perch populations have failed in significant stretches of relatively pristine <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> river that offer excellent habitat, are not silted, dammed or overfished, and where there are no possible explanations for their demise except introduced trout species. Dietary studies have documented significant overlap between the diet of Macquarie perch and introduced trout species, and anglers have observed predation of Macquarie perch juveniles by introduced trout species. Several publications in the 1940s through to the 1960s by the director of the Victorian Fisheries and Game Department (A.D.Butcher) documents predation on juvenile trout cod, Macquarie perch and other upland native fish species by introduced trout species, and major dietary overlaps. Recent research (Lintermans, 2006) records dietary overlaps that are significant by scientific criteria between Macquarie perch and introduced trout species. </p><p>Over the last 20 or 30 years, the last few remaining Macquarie perch populations in <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> habitats have faltered. All of these populations appear to be in extinction vortices and may disappear completely over the next several decades. </p><p>Macquarie perch have proved difficult but not impossible to breed. However, no Australian government agency is breeding Macquarie perch in significant numbers, and some government agencies are stocking <a href="/wiki/Upland_(freshwater_ecology)" class="mw-redirect" title="Upland (freshwater ecology)">upland</a> habitats containing remnant Macquarie perch populations with introduced trout species. Not only do these stockings threaten Macquarie perch by competition and predation, but <a href="/wiki/Rainbow_trout" title="Rainbow trout">rainbow trout</a> fingerlings have been shown to carry significant levels of EHN virus. </p> <div class="mw-heading mw-heading2"><h2 id="References">References</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Macquarie_perch&action=edit&section=5" title="Edit section: References"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-IUCN-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-IUCN_1-0">^</a></b></span> <span class="reference-text"><style data-mw-deduplicate="TemplateStyles:r1238218222">.mw-parser-output cite.citation{font-style:inherit;word-wrap:break-word}.mw-parser-output .citation q{quotes:"\"""\"""'""'"}.mw-parser-output .citation:target{background-color:rgba(0,127,255,0.133)}.mw-parser-output .id-lock-free.id-lock-free a{background:url("//upload.wikimedia.org/wikipedia/commons/6/65/Lock-green.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-limited.id-lock-limited a,.mw-parser-output .id-lock-registration.id-lock-registration a{background:url("//upload.wikimedia.org/wikipedia/commons/d/d6/Lock-gray-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .id-lock-subscription.id-lock-subscription a{background:url("//upload.wikimedia.org/wikipedia/commons/a/aa/Lock-red-alt-2.svg")right 0.1em center/9px no-repeat}.mw-parser-output .cs1-ws-icon a{background:url("//upload.wikimedia.org/wikipedia/commons/4/4c/Wikisource-logo.svg")right 0.1em center/12px no-repeat}body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-free a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-limited a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-registration a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .id-lock-subscription a,body:not(.skin-timeless):not(.skin-minerva) .mw-parser-output .cs1-ws-icon a{background-size:contain;padding:0 1em 0 0}.mw-parser-output .cs1-code{color:inherit;background:inherit;border:none;padding:inherit}.mw-parser-output .cs1-hidden-error{display:none;color:var(--color-error,#d33)}.mw-parser-output .cs1-visible-error{color:var(--color-error,#d33)}.mw-parser-output .cs1-maint{display:none;color:#085;margin-left:0.3em}.mw-parser-output .cs1-kern-left{padding-left:0.2em}.mw-parser-output .cs1-kern-right{padding-right:0.2em}.mw-parser-output .citation .mw-selflink{font-weight:inherit}@media screen{.mw-parser-output .cs1-format{font-size:95%}html.skin-theme-clientpref-night .mw-parser-output .cs1-maint{color:#18911f}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .cs1-maint{color:#18911f}}</style><cite id="CITEREFLintermans,_M.Pearce,_L.Tonkin,_Z.Bruce,_A.2020" class="citation journal cs1">Lintermans, M.; Pearce, L.; Tonkin, Z.; Bruce, A. & Gilligan, D.
