A conservation lens
Wide-ranging ocean fish can cross many jurisdictions, so bycatch, harvest limits, and international cooperation matter.
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.
