Fears for abalone stock

Joondalup Weekender - - News - Tyler Brown

THE pro­posed Ocean Reef Ma­rina de­vel­op­ment could have a dis­as­trous im­pact on abalone stocks north of the site, ac­cord­ing to North Metro Greens MLC Ali­son Xa­mon.

She re­cently told Par­lia­ment she had been ap­proached by rep­re­sen­ta­tives of the com­mer­cial abalone fish­ing in­dus­try with con­cerns about the fu­ture of the reef.

“The 3.5km abalone reef just north of the pro­posed site con­tains 40 per cent of abalone stocks in the Perth met­ro­pol­i­tan area,” she said.

“The cur­rent flows north close to Perth’s shore­line, so any im­pacts will be to the north of the de­vel­op­ment site.”

Ms Xa­mon said past ma­rina builds had seen lo­calised col­lapses of abalone stocks that had been sub­stan­tially larger than an­tic­i­pated.

“The pro­fes­sional fish­ers have told me the Min­darie Ma­rina was ex­pected to af­fect 200m of reef but in­stead abalone for com­mer­cial fish­ing was wiped out across the 1.2km reef,” she said.

“Abalone were not ex­pected to be im­pacted at all by the con­struc­tion of Two Rocks ma­rina but all abalone stocks were lost on the reef 600m north of the site.

“We do not know why the abalone are dy­ing and there has not been enough re­search un­der­taken.”

Land­Corp act­ing chief ex­ec­u­tive Dean Mud­ford said a sig­nif­i­cant num­ber of en­vi­ron­men­tal stud­ies had been com­pleted to “en­sure we fully un­der­stand the po­ten­tial im­pact of the fu­ture de­vel­op­ment on lo­cal abalone habi­tats”.

“This in­cludes hy­dro­dy­namic mod­el­ling to com­pre­hend po­ten­tial changes in en­vi­ron­men­tal con­di­tions which may im­pact abalone, which was sub­ject to in­de­pen­dent ex­pert peer re­view,” he said.

“Th­ese stud­ies are a part of the wider pub­lic en­vi­ron­men­tal re­view – the high­est level of en­vi­ron­men­tal as­sess­ment in WA – which was ad­ver­tised pub­licly for com­ment and is be­ing as­sessed by the En­vi­ron­men­tal Pro­tec­tion Au­thor­ity.

“On­go­ing mon­i­tor­ing of the abalone habi­tats will also be un­der­taken and, if re­quired, ad­di­tional mea­sures will be put in place to en­sure the abalone pop­u­la­tion is main­tained.”
