Eco details: 

Mahimahi (also known as Mahi) populations are resilient to fishing since they grow quickly, spawn frequently, and have large ranges. These fish are caught with hook and line (low bycatch) and longlines (high bycatch). The U.S. South Atlantic fishery has shown welcome initiative to establish management for this species, which is largely unregulated elsewhere.
