A member of the Malacanthidae family, the blueline tilefish (Caulolatilus microps) is found in three different regions: the Gulf of Mexico, the mid-Atlantic, and the south Atlantic. The species is also known as gray tilefish, while in Mexico it is called blanquillo lucio. In North America, this fish is eaten and it is similar in taste to golden tilefish.
The blueline tilefish generally possesses a dull olive-gray color, while the lower parts are white. The species is best known for a thin gold band underlined in blue that is visible from the nose to the end of its eye.
Its robust rectangular body also has extended dorsal and anal fins. The average length of the fish is around 24-35 in (61-89 cm).
The species generally lives at the bottom of water bodies in self-made burrows, caves, piles of rocks, or along the edges of steep slopes. This fish burrows its head in cone-shaped sand piles and a water temperature of around 59-73 F (15-23 C) is considered suitable for this fish.
Blueline tilefish generally spawn from May to October and females can lay over 4 million floating eggs.
The species is found year-round in the Gulf of Mexico, and can also be found year-round or seasonally in the south Atlantic and the mid-Atlantic region. Along with the Gulf of Mexico, you can also find the species in Maine in the north and Texas in the west.
Blueline tilefish feed on crabs, shrimp, snails, worms, sea urchins, and small fish.
The International Union for Conservation of Nature has not evaluated the status of the species as of now, but several fishery management councils have taken measures to regulate blueline tilefish fisheries, and the responsibility for implementing these rules is with NOAA Fisheries.
These measures include permits related to commercial and for-rental vessels, the introduction of catch restrictions for commercial and recreational fisheries, restrictions on fishing depending on the season, and designated areas for the protection of reef fish, sea turtles, and the bottom habitat of these blueline tilefish.
