a Life Stages: (E) = egg, (J) = juvenile, (A) = adult, and (SA) = spawning adult.b Shelter Scores: 0 = no dependence; 1 = lower dependence, not reliant on complex structure; and 2 = strong dependence, reliant on complex structure.c Food Scores: 0 = no dependence on benthic prey; 1 = includes benthic prey; and 2 = relies exclusively on benthic prey.d Reproduction Scores: 0 = no dependence (e.g., spawns in water column, or life stage not reproductive); and 1 = dependence (e.g., spawns on or over bottom).e Habitat Sensitivity Scores: 0 = not sensitive; 1 = low sensitivity (i.e., no habitat structural/complexity issues, and rapid recovery rates) such as high-energy sand habitats; and 2 = high sensitivity (i.e., habitat structural/complexity issues, and slow recovery rates) such as deepwater/low energy habitats.f Habitat Rank: = Sshelter score + food score + reproduction score + habitat sensitivity score.

g Gear Distribution Scores: 0 = gear not utilized in this habitat; 1 = gear operates in a small portion of this habitat; and 2 = gear operates in much of this habitat.h Gear Rank (i.e., overall effect on EFH of this particular gear) = habitat rank x gear distribution score. i EFH Vulnerability Category was assigned from gear ranks as follows: 0 = none, 1-6 = low vulnerability, 7-9 = moderate vulnerability, 10-14 = high vulnerability.
