Commercial shellfish harvesting has resumed in most areas of Tasmania's east coast but the scallop fishery has closed early because of a toxic algal bloom.
Thirteen harvest zones between Marion Bay and Eddystone Point were affected by the naturally occurring bloom.
After intensive testing, the Department of Health has opened the zones to commercial oyster, mussel and clam harvesting.
A public health warning is still current for crayfish, abalone, crabs, periwinkles and sea urchin.
