|Assessor(s):||Singh-Renton, S., Pina Amargos, F., Aiken, K.A., Dooley, J., Collette, B., Marechal, J. & Kishore, R.|
This deep-living species is widely distributed and occurs over hard bottom habitat. There are no known major threats, therefore, it is listed as Least Concern. Populations should be monitored in the future for quantitative evidence of decline due to exploitation.

Caulolatilus cyanops is rare off North Carolina. It is slightly more common than C. chrysops. In a 1988 survey off Tobago, this species made up 3.15% of the total catch.
Lopholatilus chamaeleonticeps and Caulolatilus microps are the primary species managed in the Gulf of Mexico tilefish quota and there is little species-specific fisheries information available for C. cyanops (SEDAR 2011).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This is a demersal species found over sandy, muddy and rubble bottoms. It has a depth range of 45-495 m, but is commonly found between 150-250 m. It is also associated with Caulolatilus microps and C. chrysops. It feeds on invertebrates and small fishes. It can co-habitate burrows of other species. Maximum size is 46 cm TL (Dooley 2002); common to 30 cm TL (Cervigon et al. 1992).|
|Use and Trade:||Caulolatilus cyanops is fished commercially using hook-and-line and trawls off Colombia and Venezuela. It may also be caught in other parts of its range as part of the reef-fish complex.|
|Major Threat(s):||There do not appear to be any substantial threats to this species as a whole. It is fished commercially using hook-and-line and in trawls off Colombia and Venezuela. There are no species-specific catch statistics and it is often confused with other tilefish species; catches reported locally as C. cyanops in the Gulf of Mexico probably correspond to C. intermedius. The habitat of this species (burrows) affords them some protection from trawling (J. Dooley pers. comm. 2013).|
In the Gulf of Mexico, tilefishes were added to the Fishery Management Plan for the reef fish fishery with the passing of Amendment 1 in 1990, under the authority of the Gulf of Mexico Fishery Management Council. Management is not species-specific. Tilefishes are subject to permanent limited access system, recreational aggregate bag limits (4 fish), gear restriction, bycatch reporting methodologies for logbooks and observer programs, moratoria/commercial fisheries closures when needed (SEDAR 2011).
Tilefishes are considered data-poor for stock assessment purposes, and therefore, have many research needs. Research priorities for the Gulf of Mexico stock include: improving abundance indices, stock definition and structure, and life history components (SEDAR 2011). The tilefish fishery off the eastern United States (which covers multiple species) was originally an open-access fishery, however, a Fishery Management Plan was put in place on 1 November 2001 which applies to Virginia/North Carolina. Tilefish south of North Carolina are managed under the Southern Atlantic Fishery Management Council's FMP for the Snapper-Grouper Fishery. The key measures taken by the Fishery Management Plan included a 10-year stock rebuilding schedule; a commercial quota divided into full-time, part-time and incidental categories; a trip limit for the incidental category; and limited entry for the full-time and part-time categories. The tilefish FMP became experimental as it did not expect cooperation nor was there a consequence for lack of cooperation. The FMP originally qualified 51 vessels for tilefish fishing, however, this number has gradually declined to 30 vessels. An annual Total Allowable Landings quota was established as well as a limited access program which established three permit categories (Rountree et al. 2008). An individual fishing quota (IFQ) program was implemented for the grouper and tilefish fisheries in 2010 (Scott-Denton et al. 2011).
