An updated statistical catch-at-length assessment for Western Atlantic Bluefin tuna

Butterworth and Rademeyer (2014) provided an initial Statistical Catch-at-Length (SCAL) assessment of the western population of North Atlantic bluefin tuna. The primary purpose in fitting to length- rather than to age-distribution data was to avoid the need to make use of the somewhat coarse cohort slicing method to provide the latter. Here these analyses are updated using comparable inputs to those agreed for the 2014 updated VPA assessments.
