There is frustration about the time it is taking Tasmanian authorities to test shellfish on the state's east coast for toxins.
Over the past month an algal bloom has closed shellfish farms and shut the scallop, rock lobster and abalone fisheries along the coast.
Triabunna business owner, Liza Gadd, said the town was already suffering from the closure of the woodchip mill.
"It's just been a real knock that the town didn't need," she said.
The fisheries will remain closed until seafood samples are given the all-clear by a laboratory in Sydney.
Dale Pearce from the Triabunna Chamber of Commerce is also concerned about the time it is taking.
"One would hope that the testing process could be done far more quickly," he said.
Wes Ford from the Department of Primary Industries said a previous investigation into establishing a laboratory in Tasmania found it was not feasible.
