Funded Activity Summary

Population declines have been identified for six albatross species, and fisheries related mortality has been implicated in these declines.From the fishers perspective, each time a bait is removed by a seabird, or a seabird is caught on a hook, the chance of catching a fish is reduced.Accidental capture of seabirds is a deleterious event from both the seabird and the fishers perspective and it is in every body’s interest to find more effective solutions to this problem

Objectives:
1. To redesign and construct an improved capsule setting device which is capable of achieving a 5 second cycle setting time at a setting depth of 3m, and is safe for crew to use in all conditions.
2. To determine the effectiveness of the capsule setting device in preventing seabirds from taking bait during setting.
3. To evaluate the impact of the capsule setting device on catch of target species
4. To define optimum installation configuration and deployment strategy of capsule setting device in relation to the influence of propeller and hull turbulence.
