Opposition leader Stephen Marshall recently announced if elected the Liberal government would reject all no take zones implemented by the Labor government.
Mr Marshall said the zones would be studied on a case by case basis to determine if they were implemented because species were in danger.
Upper Spencer Gulf Marine Park Local Advisory Group Whyalla representative Alan Hall said the removal of marine parks in the Upper Spencer Gulf would not largely affect local fishers.
He said there was a marine park south of Whyalla which extended to Cowleds Landing, however this was a marine sanctuary as it was a breeding ground, so this no take zone would stay.
"There are two others around Whyalla, one at Black Point and another at the Fairway Bank," Mr Hall said.
"The one at Fairway Bank was just a bargaining chip, because we fought for beach fishing at Black Point and gave the government Fairway Bank."
Mr Hall said with the no take zone lifted around Black Point some fishers would go back to using gullies to fish.
"I don't think they'll implement any others, because the major one is the sanctuary south of Whyalla, but they can't lift that, that'll stay as a no take zone," he said.
Mr Hall said the government should conduct a study into pollution in the Upper Spencer Gulf as this was affecting marine life in the gulf.
"There's pollution from up in Port Pirie, probably some from OneSteel and then the fishing farms because they weren't disposing of the fish waste properly," he said.
"I've had people tell me that the colour of crab meat has actually changed since the fish farms closed down."
The state election will be held in March.
