Mr Hamilton, a Raymond Terrace prawner who catches Hunter River school prawns, said he expected this year's haul to be "the same as usual".

"They will be perfect," he said.

"But it doesn't matter how big or small they are - they always taste good."

Prawning season kicks off on Monday, November 3.

The season runs until the last Friday in May with prawners able to trawl between 6am and 6pm.

On a good day, a prawner could pull anywhere between 200 and 1000 kilograms of prawns.

Last year did not start off so well for Mr Hamilton, who has been a prawner for 20 years.

"Last year I didn't catch any prawns until mid-December," he said.

"Then we had one of the best seasons to date."

Weather is always a factor for the prawn season.

It determines how well the crustaceans breed and with what force they are flushed downstream for trawlers to nab.

Mr Hamilton said he would not know whether the downpour of rain early in October would have a good or bad effect on the prawns until he got out on the water on Monday.

However, he said Hunter River was "too clear" for his liking at the moment and hoped for a storm either today or tomorrow to muddy up the water.

"Then I'll be happy," he said.
