  2. Depletion-corrected average catch: a simple formula for estimating sustainable yields in data-poor situations

    -lived species. Over an extended period (e.g. a decade or more), the catch is divided into a sustainable ... yield component and an unsustainable “windfall” component associated with a one-time reduction in stock ... biomass. The size of the windfall is expressed as being equivalent to a number of years of sustainable ... production, in the form of a “windfall ratio”. The DCAC is calculated as the sum of catches divided by the ...
