A conservation lens
Bottom-associated fish can be affected by seafloor disturbance, bycatch, warming, and changes to benthic prey.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
