SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Coryphaena hippurus

SPECIES NAME(s)

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 Atlantic, Indian, Pacific and Mediterranean populations but the genetic differentiation is not conclusive. The population structure in the eastern Pacific Ocean is unclear (Valero et al. 2019). Here, the separation of the Eastern Pacific and the Western Central Pacific stocks is based in the genetic heterogeneity found in the Pacific Ocean by Rocha-Olivares et al (2006) and due to differences in fisheries and management.


ANALYSIS

Strengths
  • Mahi mahi are fast growing and tend to be resilient to fishing pressure.
  • A National Plan of Action of Dolphinfish was implemented in Ecuador in 2011 including short and long term objectives for the fishery of this resource.
  • The impact on sea turtles, marine mammals and seabirds of this fishery is low or negligible.
