Search resumes for missing WA fisherman

The search for a crab fisherman who went missing off WA's Pilbara coast a week ago has resumed.

Norman Leslie Bale, 52, has not been seen since setting off alone on Friday last week from Back Beach boat ramp, 5km east of Karratha.

The dinghy he used was found on Tuesday near Dixon Island, about 20km from where he left, and his bag was discovered on the shoreline on Wednesday.

His workmate reported him missing on Sunday.

Police and SES will search both land and sea and an aerial search will be considered depending on weather.
