Fisheries & Water

A SURVEY of Christmas Island reefs has revealed twice as much plate coral was destroyed by a 2008 disease outbreak than previously feared.

WILUNA residents will have tastier and healthier drinking water thanks to a $1.7 million water treatment plant upgrade.

AUSTRALIAN scientists have identified cost-effective ways to help marine populations ‘bounce back’ after major disturbances, using a case study of spangled emperor (Lethrinus nebulosis) at Ningaloo Reef.

WA RESEARCH has revealed adult mangrove jack (Lutjanus argentimaculatus) are likely to be negatively impacted by climate change, but that juveniles may actually benefit from its effects.

THE sight of a shark’s dorsal fin sticking out of the water usually strikes fear into the hearts of swimmers but for a group of WA researchers every time a tagged tiger shark’s (Galeocerdo cuvier) dorsal fin stuck out of the water represented another opportunity to gather more information.

A THREE-year survey of fish species off Rottnest Island has found marine sanctuaries around the popular tourist destination are inadequate for high-risk targeted species.

REEF sharks at Ningaloo are largely home bodies but female blacktip reef sharks (Carcharhinus melanopterus), might be swimming long distances to give birth in food-rich waters, research suggests.

THE freshwater mussel Westralunio carteri has vanished from nearly half its former range, prompting the bivalves entry onto WA’s threatened species listing.

RESEARCHERS are surprised at thriving coral growth at Rottnest Island, predicting its smaller coral communities could grow into a reef similar to the one that existed there in the Last Interglacial, approximately 130,000 years ago.

EDITH Cowan University researchers are working on tools to improve future fishing management and conservation by developing effective geostatistical methods with which to model the spatial distributions of recreational fishing catch rates.
