Museum Victoria staff are involved in a fantastic citizen science project that's taking a giant nationwide leap from its starting point in Tasmania. With today's launch of the Redmap Australia website, the community is being asked to look out for unusual occurrences of species in the seas around Australia. These community sightings will help reveal if fishes and other marine species are shifting their ranges with the changing climate.

The website, also known as the Range Extension Database and Mapping Project, began in Tasmania in 2009. Already Tasmanian fishers and divers have logged hundreds of unusual sightings including Eastern Rock Lobster, Southern Maori Wrasse and King George Whiting, all spotted further south than usual.

  Southern Maori Wrasse Southern Maori Wrasse (Ophthalmolepis lineolatus) are uncommon in Tasmanian waters but more and more are being reported to Redmap along the north and north-east coasts of Tasmania. This one was snapped by diver Emma Flukes off the coast of St Helens.

Redmap founder, Dr Gretta Pecl, is a senior marine scientist at the Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania. She says Redmap "taps into the knowledge - and eyes - of thousands of fishers, divers and swimmers to track changes in fish distributions in Australia's vast coastal waters." Some three or four million Australians go fishing or diving at least once a year.

The Redmap website encourages members to share photos and anecdotes about turtles, octopus, lobsters, corals, seaweeds, urchins, prawns and marine mammals. A network of marine scientists around the country will review each photo to verify the species' identity and ensure high-quality data. Redmap aims to become not only a continental-scale range-shift monitoring program along Australia's vast coastline, but also engages Australians with marine issues using their own data.

Some seas along the Australian coast are warming at three to four times the global average. We're not sure how species will react to warmer waters - some may adapt, others may search for new habitats, while others may disappear. New arrivals of some species, especially recreational fishes, may actually benefit some communities. Understanding the movement of other species of marine pests may help minimise the risks to ecosystems or fisheries. In Victoria, fishers and divers have already been telling us about rare or uncommon fishes they've seen - including Blue Groper, Cobia, Rock Blackfish and Spotted Grubfish. Gathering sightings over time will show if these species are simply seasonal migrants, one-off visitors, or are here to stay.

I'm the coordinator of Redmap VIC and the MV team includes Martin Gomon, Julian Finn, Erich Fitzgerald and Kate Charlton-Robb. Although we'll officially be tracking some 35 species in Victoria through the Redmap project - such as octopus, Greynurse Sharks, Harlequin Fish, Striped Marlin, whales and dolphins - we're very keen to hear of sightings of other rare or uncommon species seen along our coast. You can get involved by becoming a Redmap member, signing up for the quarterly newsletter, liking Redmap on Facebook, and logging unusual marine life at www.redmap.org.au.

Di is Senior Collections Manager in our Sciences Department and is absolutely passionate about all things sciency. She loves telling people about the amazing and unique fishes found in our waters.

After a prolonged gestation, we recently launched the beautiful Fishes of Australia website in Adelaide at the Annual Conference of the Australian Society for Fish Biology

The website, funded by the Australian Biological Resources Study, is hosted by Museum Victoria on behalf of OzFishNet, a group of fish experts who work at, or are associated with, museums in Australia and the CSIRO. Senior curator Martin Gomon and I worked with the museum's in-house design and development team to build the site, which will appeal to everyone with an interest in Australian fishes, whether they be divers, anglers, aquarists, students, teachers, or researchers.

Australia's amazingly rich and diverse fish fauna comprises about 5000 species. With so many fishes, the website is a work in progress, but photographs of over 800 species are already in the website's gallery. Eventually, we'll include detailed images and information on all Australian fishes – including tiny desert gobies from hot artesian springs in central Australia, weird and wonderful deep-sea critters found offshore, and all species on the Great Barrier Reef.

We're also including fishes found in our territorial waters – those from our Antarctic and Subantarctic waters, plus the fishes of Ashmore, Cartier, Lord Howe, Norfolk, Christmas and Cocos Keeling islands.

We've included a couple of user-friendly interactive keys – one to fish families, and the other to freshwater fishes (including the nasty introduced ones). Try them out on that weird fish you caught last summer, or put a name on your favourite aquarium species. We thank the many fantastic photographers who have allowed us to use their gorgeous images that illustrate the site.
