Fisheries officers with the Department of Primary Industries and Regional Development inspected the man’s vehicle in February last year at the Coodanup Foreshore and found 36 blue swimmer crabs, with 28 undersize.
Officers released all of the crabs back into the water.
DPIRD Senior Fisheries and Marine Officer Darren Harbord said the daily bag limit for blue swimmer crabs was 10 crabs per fisher per day with a legal minimum size of 127 mm measured across the carapace.
Mr Harbord said the bag limit was strictly enforced to protect breeding stocks in the estuary.
“Fishers should always measure their crabs carefully from the tips of the spikes across the widest part of the shell before taking them ashore,” he said.
“Once the crabs are placed in a bucket or catch bag they are deemed to be taken and in the possession of the fisher.
“It is important for crab fishers to carry a gauge to measure each crab as soon as its caught so it can be returned promptly to the water if undersize.
“High-grading - taking crabs and discarding them later for larger crabs – could put pressure on crab stocks, as discarded crabs may not survive.”
