Stop the Super Trawler Alliance member Kevin Harkins plans to register the Australian Recreational Fishers Party within months and could field Senate candidates at the next election. The move comes amid mounting concerns about the 95-metre Geelong Star – a slightly smaller vessel than the banned FV Margiris – which began operating in Tasmania last week.

Hundreds of angry anglers and concerned environmentalists joined forces at  Perth on Saturday to rally against the Geelong Star’s presence. The rally was attended by protesters from across the state, including the North-West, East Coast and Hobart.

Game Fishing Tasmania spokesman Nobby Clark said fishers would do what  was necessary  to make their point.

‘‘We don’t want to start a political party, but if it comes to that then we will,’’ Mr Clark said.

‘‘It’s ridiculous how far this has gone. We’re disappointed to be in this situation again.’’

Labor Senator Helen Polley attended the rally, along with Greens leader Kim Booth. Mr Booth said the science behind super trawlers was flawed. 

‘‘The science is not in to justify the plundering of this fishery,’’ Mr Booth said.

‘‘Serious concerns remain about localised depletion of fish stock  and the consequences for other marine species further up the food chain, including southern bluefin tuna, seals and dolphins.’’

On Friday, Liberal Senator Richard Colbeck said: ‘‘The latest science clearly shows the small pelagic fishery can be fished sustainably, but Labor and the Greens appear hell-bent on destroying the fishing industry in Australia. 

‘‘Australia’s fisheries are recognised among the best in the world, and our fisheries management is based on the best available science.’’
