Document occurrence of tropical fishes within temperate reefs in the east coast of Australia and evaluate the role of the East Australian Current in facilitating their presence
Type of Study:
A total of 47 species of tropical fishes from 11 families were observed during the summer recruitment season (January to May) in NSW. Density and species richness tended to be higher in northern NSW sites. Little evidence that individual recruitment events were correlated with local increases in water temperature inferred to be associated with East Australian Current ingresses.
Understanding dynamics of larval transport in eastern Australia will allow to better track potential range shifts and population dynamics of fish stocks, which will enable more effective management and conservation
