Log-a-fish website makes a splash in NSW waters

The University of Newcastle will lead the New South Walesrollout of an interactive reporting website encouraging the community to log uncommon catches or unusual sightings of marine life.

Redmap* www.redmap.org.au (Range Extension Database and Mapping project)has been operating in Tasmania since 2009 and is now being introduced Australia-wide to better track marine movement.

Coordinator of Redmap NSW Associate Professor NatalieMoltschaniwskyj, a marine ecologist at the University of Newcastle, said Redmap would tap into the marine knowledge of the 3.5 million Australians who gofishing or diving at least once a year.

"Redmap encourages the community to submit sightings ofall marine life including fish, turtles, sharks, rays, crayfish, corals,seaweeds, urchins and prawns," Professor Moltschaniwskyj said.

"Due to ocean warming, we've noticed more warm-water fish venturing away from their usual homes. For example, tropical species usuallyseen in southern Queensland are being seen in Port Stephens and as far south asSydney Harbour."

"Gathering sightings over time will show if these fishare here to stay, one-off visitors or just seasonal migrants."

Redmap founder and marine biologist Dr Gretta Pecl, fromthe Institute for Marine and Antarctic Studies (IMAS) at the University ofTasmania, said photos and data submitted would be reviewed by a network ofmarine scientists across the country.

"Each sighting is a piece of the puzzle that over time will reveal which species or regions may be experiencing greater changes in marine distributions," Dr Pecl said. "Some seas along the coast of Australiaare warming at two to four times the global average and while some species may adapt to changing water conditions, others may even disappear."

Dr Alan Jordan from the NSW Department of Primary Industries said Redmap's community observations would provide an early indication of marine shifts, allowing management and research to be better channelled into the key regions.

"This information will alert the marine community to newfish arrivals and minimise the risk for those fisheries or regions that may bemore impacted by species on the move," Dr Jordan said.

* Redmap NSW is supported logistically and financially byThe University of Newcastle, NSW Department of Primary Industries, Southern Rivers CMA, Community Environment Network, Central Coast Marine Discovery Centre, and C2O Fisheries Consulting; it also receives support from many fishing, diving and community groups around the country. Redmap Australia is hosted by IMAS at the University of Tasmania. The expansion of Redmap nationally was made possible with funding from an Australian Government Inspiring Australia grant, the Australian National Data Service (ANDS) and the Department of Agriculture, Fisheries and Forestry (DAFF).
