who is the atlantic rubyfish
Fish of the family Emmelichthyidae, the rovers (peixes-rubi), reaching 65 cm. It lives near the bottom, over sand and mud, between 90 and 300 m, on the shelf and slope, and the common size is about 40 cm. It occurs in the western Atlantic, from South Carolina to the Bahamas and Venezuela, and also in the eastern Atlantic, from Senegal to Angola. It feeds on larger zooplankton. It is a commercial catch and is almost never seen in rod fishing.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the atlantic rubyfish; in the meantime, see the similar species.
identification
Fish of the family Emmelichthyidae, the rovers (peixes-rubi), with an elongated body, living near sand and mud bottoms between 90 and 300 m. Size is the best clue for telling it apart from the red rover (Emmelichthys ruber), which reaches 30 cm, while this one reaches 65 cm. As both species live in similar depth ranges, check the length of the fish before deciding.

Essential profile: the index uses a general fish model (weather, sun, moon and tide), without a season or time of day specific to this species.
where found
In Latin America, it occurs in Mexico, Colombia and Venezuela, over sand and mud bottoms, and also in the North American Atlantic and the Bahamas.

rules for the atlantic rubyfish
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
We found no species-specific rule beyond the region's general rules.
catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.
No danger to the angler. It lives on bottoms of 90 to 300 m, and rapid ascent causes barotrauma, so release calls for care.
in the kitchen
Sold fresh or frozen, and also made into fishmeal and fish oil.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.01072, b = 3.07; FishBase (relação peso-comprimento bayesiana, estimativa)). It's an average: a fat or lean fish can vary by 10% to 20%.
