The Coral Triangle is a centre of biodiversity for a very wide variety of tropicalmarine organisms. Amongst the fishes, the groupers are one of the more iconicgroups important to the fisheries, and to the overall economy of the CT region.Groupers are one of the most important fish groups in the Live Reef Food FishTrade, and fetch a very high price in markets. This high economic value is not onlyvery significant to the fishermen involved in the trade, but imposes its own seriousproblems in terms of the sustainability of the fisheries into the future. One of themost effective measures for the protection and conservation of groupers is theestablishment of appropriate MPAs.

Current levels of harvest of groupers are currently unsustainable. Grouperproduction has steadily been increasing over the last 60 years due to the increasingdemand for live fish. In view of these fisheries demands, and the intrinsicvulnerabilities of this particular group to fishing pressures (i.e. generally slowgrowing, late maturing, sex changing, relatively long lived, often grow to a largesize, have a high trophic level in the food chain, and often form spawningaggregations which are highly susceptible to fishing), they were considered apriority group for IUCN Red List assessments. A Red Listing workshop was held inHong Kong in Feb 2007 by the IUCN Grouper and Wrasses Specialist Group and theGlobal Marine Species Assessment.
