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 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. However, Vietnam is not part of the WCPFC, and therefore, two management units are considered in this profile. 


ANALYSIS

Strengths
  • Because of the life history characteristics, mahi-mahi is considered to have low susceptibility to over-exploitation. 
  • Commercial fishers have a legal obligation to report information about their fishing activities (including bycatches and interactions with ETP species) in a compulsory daily logbook.
  • Handline fishing gear is acknowledged as environmentally friendly fishing.
