Default assessment strategies: indicator species, complexes and assignment

Starting points for the assessed, complexes and assign arguments of hcr_effort(), derived from the system:

Usage

ms_assessment_presets(sys, own_q = 0.5)

Arguments

sys

an ms_system.

own_q

as in hcr_effort().

Value

A list with indicators (stock names), complexes (named list of stock names) and assign (named list segment -> stock names).

Details

• indicators: one indicator species per segment, the stock of highest potential value to that segment (catchability on its metiers x price x K) among the stocks it catches as a main fishery, without repeats;

• complexes: the species groups of the system with two or more stocks (stocks alone in their group stay single units);

• assign: each stock assigned to the segment for whose fishery it matters most (its largest share of the segment's potential value), its "main" fleet.
