New South Wales Fisheries has welcomed the two-month jail sentence handed down to a man for abalone poaching on the New South Wales far south coast.

The 33-year-old from Batemans Bay was found at Narooma with almost 400 abalone, amounting to around 32kg of shellfish meat.

The department's operations manager, Tony Andrews, says the case proves there are systems in place to catch offenders.

Mr Andrews says he is pleased that the courts have recognised the severity of the crime.

"We've got a repeat offender here, with extensive history of fisheries-related crimes and it's identified that this is obviously a very serious abalone matter," he said.

"That's quite a substantial recognition by the judiciary that, how serious these matters are."
