Susceptibility attribute Low susceptibility (low risk, score = 1) Medium susceptibility (medium risk, score = 2) High susceptibility (high risk, score = 3)
Availability < 10% overlap 10 – 30% overlap > 30% overlap
Encounterability Low overlap with fishing gear (low encounterability) Medium overlap with fishing gear. High overlap with fishing gear (high encounterability). Default score for target species.
Selectivity a.       Individuals < size at maturity are rarely caught. a.       Individuals < size at maturity are regularly caught. a.       Individuals < size at maturity are frequently caught.
b.       Individuals < size at maturity can escape or avoid gear. b.       Individuals < half the size at maturity can escape or avoid gear. b.       Individuals < half the size and maturity are retained by gear.
Post-capture mortality Evidence that majority are released post-capture and survive. Evidence that some are released post-capture and survive. All individuals are retained, or the majority are dead when released. Default score for retained/target species.
