"We'll be providing more Australian product but the catch has been limited," he said.

The outbreak of white spot disease in prawn catchments across Australia has created problems for the industry, rapidly depleting stocks amid fears the contagion would spread.

Mr Fragopoulos said the majority of prawns were being imported, and catering companies and distributors were coming to grips with the reality of Australian product available.

"There's just not enough to meet the local demand. We have had, from our wholesale distribution, a lot of disappointed customers," he said.

"They are available but very expensive."

Mr Fragopoulos said he would be freezing what stock was coming in to hold out for the next 12 months before the next prawn season.

Ocean Fresh Seafoods owner Chris Russell said he was expecting standard prices for his wild-caught prawns.

Wild-caught prawns aren't victim to the white spot outbreak affecting prawn farms across the country.

"This season has been very good still, there's been good catches up north," Mr Russell said.

His prawns have been flown into Canberra from north of Townsville the last few nights.

"Average prawn price will be $35 through to $45 a kilo," Mr Russell said.

He expected bumper trade this weekend, saying Easter was always a strong point.

"Traditionally with Easter, ten years ago, it used to be all about fish but there's been a swing towards more crustaceans," Mr Russell said.

White spot disease has crippled prawn and other crustacean breeders after hitting Moreton Bay and Logan River in Queensland.

The Queensland Department of Agriculture and Fisheries is working to drain and decontaminate seven prawn farms on the Logan River that were impacted by white spot disease, a highly contagious viral infection affecting crustaceans.

While prawn farms avoided inundation when the Logan River flooded after Cyclone Debbie, heavy rainfall set back efforts to dry them out for decontamination.

The department believes decontamination on all farms south of the river will take months.

Chief biosecurity officer Dr Jim Thompson told Fairfax Media in February it intended to have affected farms operating again towards the end of the year.

Queensland seafood farmers have pushed back against a proposed levy to combat the white spot disease, saying the outbreak was the fault of biosecurity officials.

The federal government's proposed levy would contribute to a $36 million fund, to be used like insurance for farmers and the government against stock losses, clean-up and eradication.
