Appendix II. Priorities for bycatch monitoring
This list includes the deep-water (>80 m) sponges presented
in this guide. Each species is ranked from low
(1) to high (3) for its importance as fish habitat and
its vulnerability to disturbance from fishing activities.
Ranks for these two measures are averaged to provide
