Though recent landings of Mycteroperca venenosa from Brazil and Bermuda are lacking and no inference can be drawn about the status of Yellowfin Grouper around these regions, M. venenosa occurring around the Caribbean areas is clearly facing heavy fishing pressure. The large level of decline in landings in regions around the U.S. and the poor status of some of its spawning aggregations are all likely evidence to of heavy fishing pressure. Considering this situation and the importance of this grouper to Bermuda’s commercial fishery industry (Heemstra and Randall 1993), it is very likely that future Yellowfin Grouper populations in some areas will be deeply affected by its current situation unless conservation actions are made promptly.
Recent data on landings of M. venenosa are only available from the U.S., mainly U.S. Caribbean. The percentage of the U.S. landings showed a 94% decline in 11 years (1990–2001).
In Bermuda, landings of M. venenosa showed a decrease of about 80% from 1975 to 1981 (4.5 mt to 0.9 mt) followed by an increase in 1987 (2.5 mt). Recent data from Bermuda or Brazil are lacking but management has been in place in Bermuda with some improvement noted.
In Cuba, Mexico and Belize, spawning sites showed declines and some of them are commercially exploited. Exact data on exploitation of spawning aggregations are lacking.
See the Supplementary Material for a summary of the regional catch data.
Recent data on abundance and population status (except for the U.S. mainly Caribbean stock) and appropriate data on exploitation on spawning aggregations are lacking. However, U.S. and probably Bermuda stocks are facing heavy fishing pressure. As others groupers which gather to spawn, M. venenosa is particularly particularly vulnerable to overexploitation, especially when fishing pressure is most intense during spawning aggregation formation. However, in some areas this species is ciguatoxic and not heavily taken for food. This species should be considered Near Threatened with additional data sought and more effective management is probably needed. It is close to a Vulnerable listing under criteria A2d.
|Range Description:||Mycteroperca venenosa has a rather continuous distribution along the east coast of Central America within the Caribbean and along the east coast of South America, south to Sao Paulo (Brazil), with only an interruption near the exit of the Amazon River. Extent of occurrence and area of occupancy are unknown.|

|Population:||Populations in the Caribbean area are suggested to be large historically (Heemstra and Randall 1993), although current population size may be considerably reduced as inferred from the landings of it in the U.S. and territories and the status of its spawning aggregations. Population doubling time: 4.5–14 years (FishBase 2003).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Juveniles occur in shallow turtle grass beds; adults are usually found on rocky and coral reefs in depths of 2 to 137 m (FishBase 2003). |
Spawning takes place at Bermuda in July, in the Florida Keys during March (at least formerly but not confirmed recently), and on the Florida Middle Ground in the eastern Gulf of Mexico from March to August (Bullock and Smith 1991, Heemstra and Randall 1993). In Cuba, Yellowfin Grouper spawns during winter and spring with peaks spawning in January and during April-May (García-Cagide and García 1996). Spawning takes place south of St. Thomas (Grammanic Bank) February through April with peaks during the full month in March.
|Major Threat(s):||Most likely threats are overfishing and habitat destruction. Extremely vulnerable during spawning aggregations.|
The Caribbean region
A series of conservation strategies is proposed to protect the spawning aggregations in the Caribbean region, this includes incorporating known spawning aggregation sites into planning programmes, developing and implementing monitoring programmes, imposing gear restrictions (Luckhurst 2003). The Gramanic Bank area south of St. Thomas has been proposed as a seasonal area closure to protect Yellowfin Grouper.
No known restrictions on trade in this species are imposed in any Caribbean countries.
Regulations for all groupers caught on the Campeche Bank (including M. venenosa) include license and a minimum legal total length of 30 cm, a closed season from January 15 to February 15 and an annual catch quota of 1,200 mt for the Cuban fleet. (SEMARNAP 2000).
