The government is reminding fishermen of the minimum size of shellfish that can be caught in Manx waters.
It comes after a local man was fined £10,000 for being in possession of undersized lobsters.
The regulations are in place to protect the sustainability and conservation of stocks around the Island, as letting them stay in the sea for longer helps boost the population.
The minimum size of lobsters increased last year after a public consultation, and is set to increase to 90mm in September.
