ABALONE fishers are warned to take care on Sunday, the second day of the heavily restricted season, following the death of a Malaysian fisherman on the first day.

A 20-year-old Malaysian man was swept into heavy seas by a strong rip in Yanchep Lagoon, 55km north of Perth, on November 4.

The accident triggered calls for metropolitan abalone fishing spots to be closed in dangerous weather.

Instead, Surf Life Saving Western Australia (SLSWA) will put on additional patrols and has urged fishers to be cautious.

"With the body of the fisherman still missing and 15 rescues performed on November 4, surf lifesavers are calling for abalone fishermen to not go beyond their own capabilities or take risks on Sunday," SLSWA community safety manager Chris Peck said.

Department of Fisheries principal management officer Martin Holtz advised abalone fishers to be aware of the water and weather conditions, and wear appropriate clothing and footwear for clambering over reef tops.

Sunday is forecast to be mainly sunny, with temperatures reaching a maximum of 30C.

The abalone season is open for five days between early November and early March, and only for one hour a day.
