St Helens' Salty Seas owner Rod Elliott said he was inundated with customers in the four days leading up to Christmas and had no idea when the rush would stop.

Mr Elliott said prawns and crayfish had been the most sought after sea critters for a festive feed along with scallops, oysters and crab.

"St Helens goes crazy from Boxing Day onwards although it has started earlier this year," he said.

"The business (Salty Seas) closed down about six months ago and I have only just reopened it, but I believe from previous owners it is chaotic this time of year.

"Seafood is simple and served cold - the traditional roast meal is pretty much knackered at Christmas."

Mr Elliott was selling the popular rock lobster for $87 a kilogram, however, the price was up to about $100 a kilogram in some places in the area.
