Recreational fisher and anti-super trawler campaigner Todd Lambert will run in Bass and Brett Smith, who was part of the campaign against a tourism development at Lake Malbena, will run in Braddon.

"Given recreational fishing is a huge part of our Tasmanian lifestyle and injects so much into our local economy, it is vital we (recreational fishers) remain a powerful voting bloc as, in my opinion, our fisheries remain under attack from corporate greed on so many levels, environmentally, socially and economically," Mr Lambert said.

"I believe through the powerful voting bloc that are recreational fishers, our concerns and voices are finally starting to be heard and, by running, myself and others can perhaps glean a better outcome for us all as both parties seek our support within this area.

"To have two rec fishers, Mark Duncan and Craig Garland, running in the Senate, along with Brett Michael Smith (Braddon), who has been a strong campaigner on the Lake Malbena issue, (and) myself in Bass, we should shake both the majors up once again, one would hope."

Mr Lambert, who was president of the Recreational Fishers Party at the last federal election, said he only decided to run during the Easter break, "mainly through frustration borne out of continually being ignored by (Liberal) Senators (Jonathon) Duniam, (Eric) Abetz and (Richard) Colbeck".

"I wrote to them all twice over the six-month period leading up to this election and put forth the question: Would the Liberal Party consider following federal Labor's lead in announcing their intention to legislate the banning of foreign owned freezer factory trawlers (referred to as super trawlers) from exploiting our small pelagic fishery within our commonwealth waters?"

Mr Lambert, a former union official, denied his candidacy was a ploy to help Labor.

He said he had campaigned against former Labor MHRs Sid Sidebottom and Dick Adams over the trawler issue and had not been a Labor member for more than 20 years.

Comment was being sought from the Liberals.

Asked why he was standing, Mr Smith said he had fished recreationally all his life and did not want to see Tasmania "ruined for the next generation".

"I feel as a voter bloc we have been ignored by both sides of politics."

A farm hand from Devonport, Mr Smith said health, education and, especially, aged care were big issues for him.

He was the spokesperson for a group which opposed helicopter access to a standing camp in the Walls of Jerusalem National Park.
