Throughout the world, there is a growing recognition of importance and need for incorporation Indigenous Traditional Ecological Knowledge (TEK) First Nations peoples in shellfish aquaculture coastal management. In Australia, however, TEK management its infancy. This concern because combined perspectives knowledge Western Science are needed to restore culturally economically significant create successful, respectful sustainable outcomes.

Environmental Conditions Associated with Four Index Cases of Pacific Oyster Mortality Syndrome (POMS) in Crassostrea gigas in Australia Between 2010 and 2024: Emergence or Introduction of Ostreid herpesvirus-1?

Warm water temperature is a risk factor for recurrent mass mortality in farmed Pacific oysters Crassostrea gigas caused by Ostreid herpesvirus-1, but there little information on environmental conditions when the disease first appears region—the index case. Environmental between four cases Australia (2010, 2013, 2016 and 2024) were compared to provide insight into possible origins of virus. Each case was preceded unusually low rainfall higher rates change that could increase oyster susceptibility through thermal flux stress. Water alone did not explain cases, being no consistency sea surface, estuary or air temperatures them. Tidal cycles chlorophyll-a levels unremarkable, harmful algae present all anthropogenic contamination unlikely. The lack an interpretable estuarine environment suggests recent introduction OsHV-1; however, viral emergence from local reservoir cannot be excluded. Future events will difficult predict. Temperature are likely important, they proxies range undetermined factors identify these, it necessary develop comprehensive protocols data acquisition during future cases.

Profiling Inter‐Specific and Inter‐Estuarine Variation in Per‐ and Polyfluoroalkyl Substances Across Two Recreational Fishing Havens

Fisheries Management and Ecology, Journal Year: 2024, Volume and Issue: unknown

ABSTRACT Contamination of estuaries with per‐ and polyfluoroalkyl substances (PFAS), such as perfluorooctane sulfonate (PFOS), may impact recreational fishers who consume their catch. However, the presence concentration PFAS across commonly harvested estuarine taxa is rarely quantified. We used data from a state‐wide survey to design conduct sampling program for assessing contamination two fishing havens (Lake Macquarie Botany Bay, New South Wales, Australia). Perfluorodecanoic acid (PFDA) PFOS were primary contaminants in edible tissues recreationally species, concentrations highly variable. In Lake Macquarie, all samples below screening criteria, invertebrates both estuaries. some fish exceeded but most frequently species had lowest Ecological factors likely contributed substantial variation accumulation levels among different species. Recreational fisheries surveys provide solid foundation frame investigations exposure risk support development spatially tailored dietary advice.
