China has halted live animal trade over fears the trade could help spread the disease.
South Africa, which has no confirmed coronavirus case, has been hit hard by the suspension of lobster exports to China - which last year bought 95% of its total allowable west coast lobster catch of 1,084 tonnes.
The West Coast Rock Lobster Association, which represents offshore and near-shore rights holders, said the outbreak has had a "serious impact" with direct financial losses to rights holders estimated in excess of 257 million rand ($17 million).
"But, then there is the secondary effect on the people working the factories processing less lobster, the people catching it will be taking out less fish ... so our fishing communities will have less money," said the association's chairwoman, Shamera Daniels.
There were almost 50 tonnes of live crayfish at risk of dying, being frozen and sold at a significant discount, she said.
The industry was in discussion with the government about possible interventions, Daniels said, such as extending the fishing season should China's trade restrictions persist.
Ocean View's fishermen said their survival was at stake.
"We are basically the worst off because of the coronavirus," said fisherman Charles America. "The effects might be economic or financial in the upper echelons of the industry, but down on the ground here it is survival, pure survival."
