Mycteroperca tigris (Valenciennes, 1833)
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Garcia-Moliner, G. (Grouper & Wrasse Specialist Group)|
|Reviewer(s):||Sadovy, Y. & Eklund, A.-M. (Grouper & Wrasse Red List Authority)|
Currently classified as Least Concern although landings data of Mycteroperca tigris from both areas in North America and Brazil are lacking. With the other data available, and considering the relatively wide distribution of this fish, its current population is not likely to be at great risk but the current taking of it from spawning aggregations is very likely to affect populations exploited in this way if this practice is not managed. Also, data from underwater visual census suggests possible declines of this species in the Greater and Lesser Antilles. More data should be sought to allow a more detailed evaluation of this species and the species should be re-evaluated as soon as possible.

|Population:||The population is not likely to be fragmented and population size cannot be deduced from data available. Minimum population doubling time is 4.5-14 years (FishBase 2003).|
|Habitat and Ecology:||
It occurs in coral reefs and rocky areas and is an ambush predator (FishBase 2003). Spawning aggregations of several hundreds of fish take place approximately one week following each full moon during the months of January to April at the east of Vieques Island, Puerto Rico (Sadovy et al. 1994).
Tiger Grouper becomes sexually mature female between 25-35 cm total length (Sadovy et al. 1994).
|Major Threat(s):||Overfishing and habitat destruction are the two most possible threats.|
A tag-and-release project was initiated in 1996 to study spawning aggregation size and site fidelity (Matos and Posada 1998).
A series of conservation strategies for spawning aggregations in the Caribbean region is proposed. They include incorporation of known spawning aggregation sites into planning programs for Marine Protected Areas, development and implementation of monitoring and management programmes (Luckhurst 2003).
