A Tasmanian man has been fined $2000 for illegally possessing 16 southern rock lobsters, including one that was undersized.
Police stopped and searched the George Town man's car in Westbury, west of Launceston, on Monday.
They found the 16 lobsters the man had caught at Strahan on the West Coast.
Recreational fishing rules prohibit a person from possessing more than 10 lobsters taken form western Tasmania without a special licence.
The daily catch limit for the region is also five lobsters per day.
The state's rules around recreational fishing were tightened last year in an effort to improve stock levels and spawning opportunities for future sustainability.
Westbury Police Senior Constable Christopher Rockliff said the laws were in place for a reason.
"Recreational fishers should review the new rules, which include different methods of tail clipping, increased size limits and reduced daily bag and total possessions limits in some areas," he said.
"The rules are reviewed in line with changing stock levels and penalties reflect the importance of protecting the fishery industry and ensuring sustainable fishing into the future."
