- There is definitely increasing evidence of climate-change induced range shifts for Aussie fishes, especially in SE Australia where we have the dual effects of increasing sea temperature and East Australian (EAC) current flow. We have been studying the influx of coral reef fish larvae into the Sydney and southwards. (summary can be heard at http://www.aqob.com.au/details.php?p_id=717&search=booth&searchid=1&seo=No_small_change Basically, the numbers vary greatly year to year, partly depending on EAC patterns. However, we also showed a strong link between winter water temperature and overwinter survival of these fishes (tropical butterflyfishes and damselfishes)- we saw survival over about 18C, which occurred in 2001 and 2006, 2 of the warmest winters in 150 years! A lot more needs to be researched and the jury is still out on whether we might seem major biogeographic shifts in fish species. I’d also suggest talking a look at the recent Marine Climate change Report Card for Australia at http://www.oceanclimatechange.org.au/content/index.php/site/welcome/ Our “temperate fishes” paper in that, plus those on tropical and pelagic fishes are relevant.
