The Tropical Tuna Resource Assessment Group is the key research and scientific committee for management of the Eastern Tuna and Billfish Fishery and the Western Tuna and Billfish Fishery. The Tropical Tuna Resource Assessment Group was formed in 2010 and two or three meetings are generally held each year.
The group provides advice to the Tropical Tuna Management Advisory Committee on the status of fish stocks, sub stocks, species (target and non-target), the impact of fishing on the marine environment and the type of information needed for stock assessments. They also evaluate the impact over time of different harvest strategies, stock depletion and recovery rates, confidence levels for fishery assessments and risks to the success of fishery objectives. Compliance and economic factors affecting the fishery are also evaluated and reported on by the group.
This group provides an avenue for consultation between industry members, fishery managers, fishery economists, fishery scientists and other interest groups.
