or use lobster pots, while commercial fishers catch lobsters by trawling. The total catch in 2011 was of J. edwardsii, of M. challengeri, and of Sagmariasus verreauxi. Recreational fishing of lobsters ("crayfishing") in New Zealand does not require a permit provided catch limits, size restrictions, and seasonal and local restrictions set by the Ministry for Primary Industries (MPI) are followed. The legal recreational daily limit is six lobsters per person, with a maximum of three lobster pots permitted per person. Lobsters cannot be taken if they are in berry (carrying eggs) or in the soft shell stage. For J. edwardsii, the minimum legal size is 54 mm for males (no pincers on the rear legs and single pleopods) and 60 mm for females (pincers on the rear legs and paired pleopods), measuring the width of the tail over the primary splines on the second segment. Australia A number of species are targeted around the coasts of Australia. Jasus edwardsii is found off Australia's southern coast, from Western Australia to New South Wales, as well as in New Zealand. Thenus orientalis, known as the Moreton Bay bug, is fished on the country's north coast. Safety Lobster fishing is considered a hazardous occupation by NIOSH. Lobster fishermen who become entangled in their trap line are at risk of drowning if they are pulled overboard. Best practices have been developed to prevent and reduce entanglement, and to facilitate getting fishermen who have fallen overboard back onto their vessels. Fishing safety can be found in many manuals and courses can be taken to ensure that your vessel and crew are up to date on all of their safety procedures to reduce the risk of injury or drowning. There are many policies to be followed for many things such as on-board working procedure, maintenance and more. Environment There are procedures in place to minimize the amount of pollution in the water while fishing. If a spill were to take place on a vessel, the first thing is to minimize the amount and prevent as much from entering the water. A pollution kit should be aboard every vessel in case of a spill.
