Neptune's Alaska Cod and Crab Triggers have been in use for over 12 years. They are used to modify large crab pots so they can be used in the directed Pacific cod fishery and in the deep water fishery for brown king crab.

In New Zealand, Neptune "Necks" are used on top entry lobster traps to help improve their efficiency. They have proven to be very effective in reducing escapement and increasing catches. The

Neptune entrances proved to be too efficient for the fishery managers in the Western Australian lobster fishery. They were banned in the early 90's due to the government's worry about the increased catching ability of the modified traps in a trap limited fishery.

Neptune entrances are adaptable to a number of other lobster fisheries around the world. Creative fishermen have found numerous ways to modify their lobster traps to increase catches using Neptune devices. Facing the prospect of trap limits in a number of lobster fisheries, many fishermen are looking for methods to make their existing traps fish better. Neptune entrances provide the ideal means for fishermen to develop the better lobster trap.
