Illustration of a suggested simple approach for recommending Atlantic bluefin TACs for the 2021 season

A simple approach for recommending the Atlantic bluefin TACs for the 2021 season is put forward. It is based on the concept of maintaining the current fishing mortality in each of the West and East areas by adjusting immediately preceding TACs in proportion to an inverse-variance-weighted average of recent trends for the various abundance indices. An example is used to illustrate the approach.
