The Humphead Wrasse, Cheilinus undulatus
The Humphead wrasse, Cheilinus undulatus, is the largest member of the family Labridae and widely distributed across the reefs of the Indo-Pacific. It is found from the Red Sea and African coast, across the Indian Ocean and much of the Pacific, north to southern Japan and the coast of southern China, and south to New Caledonia. In English it is mostly commonly referred to as the Humphead, Maori or Napoleon wrasse.
Fishery management
The species has a high economic value and is a special favorite of both the live reef food fish trade and with recreational divers.The Humphead wrasse is vulnerable to fishing due to its long life and late sexual maturation (which occurs at approximately 50 cm total length and 5 years of age). This means that its life history is one that involves slow replacement (and hence slow recovery from fishing) rates. Because of its high value as food, it is heavily sought by fishers and traders. As part of the live food fish market, its value is likely to increase with rarity, so fishers will continue to fish this species even as its numbers decline. Humphead wrasse fisheries are mostly unmanaged and, even if managed on paper, there is usually little management or monitoring of Humphead wrasse in local fisheries. Monitoring is needed, both of local capture and of exports. Without proper management and monitoring, it is impossible to know whether current capture rates are sustainable or to establish safe quotas capture. On the other hand, its value to diving tourism will remain high if it is protected and remains alive in the wild.
