Updated progress report: a multi-stock model for North Pacific sei whales, with preliminary results

SC/67B/IA/01
The age-, sex-, and season-structured population dynamics model developed to conduct an assessment of North Pacific sei whales is updated to use the available data types (catches, estimates of absolute abundance, estimates of relative abundance, and mark-recapture data). Preliminary applications of the model based on 1-stock and 3-stock hypotheses indicate some conflicts between the catch and abundance data. The data are preliminary and the results should be considered in that context.
