Common dolphinfish, Mahi-mahi
The stock structure of the species is not truly known at a global scale. Díaz-Jaimes et al. (2010) studied the inter-oceanic divergence of the Atlantic, Indian, Pacific, and Mediterranean populations but the genetic differentiation is not conclusive. Here, the separation of the Eastern Pacific and the Western Central Pacific stocks is based on the genetic heterogeneity found in the Pacific Ocean by Rocha-Olivares et al (2006). No stock assessment is being carried out.
The Western and Central Pacific Fisheries Commission (WCPFC) is responsible for the conservation and management of Highly Migratory Fish Stocks, such as the common dolphinfish population, in the Western and Central Pacific Ocean. This profile is structured around the WCPFC management unit.
