The Cobia fish belongs to the Rachycentridae family. it can be 1.8 m long and weigh 70 kg or more. it can live 12 years. The spawning period depends on the location. It can be fished all year round.
The body is elongated and torpedo-shaped with a long flattened head. The eyes are small and the snout is wide. The lower jaw protrudes beyond the upper jaw. The skin is smooth with very small integrated scales. Easily distinguished by the first dorsal fin, composed of 7 to 9 strong and isolated spines, not connected by a membrane. The second dorsal fin is long with the front part elevated. The caudal fin is rounded to truncated in young fish and lunar in adults, with the upper lobe extending below the lower lobe. The origin of the anal fin is below the second dorsal vertex and the pectoral fin is pointed. Cobia doesn’t have an air bladder. The body is dark brown to silvery, paler on the sides and greyish white to silvery underneath, with two narrow dark bands extending from the snout to the base of the caudal fin. These dark bands are bordered at the top and bottom by lighter bands. Young cobia has dark side bands, which tend to become obscured in adult fish. Most fins are dark brown, with grey markings on the anal and pelvic fins.

The cobia fish lifestyle

The cobia is a voracious eater; it often swallows its prey as a whole. They are carnivores that eat crustaceans, cephalopods and small fish such as mullet, eels, jacks, snappers, crayfish, croakers, grunts and herring.
It breeds by day between June and August in the Atlantic Ocean near Chesapeake Bay, off North Carolina from May and June, and in the Gulf of Mexico from April to September. During the reproduction, cobia undergo body color changes from brown to a light horizontal stripe pattern, releasing eggs and sperm into open offshore waters. Cobia eggs are spherical and average 1.24 mm in diameter. The larvae hatch about 24 to 36 hours after fertilization. These larvae are 2.5 mm long and lack pigmentation. Five days after hatching, the mouth and eyes develop, allowing an active diet.

The Cobia fish habitat

It is a pelagic fish that lives on the continental shelf as well as near offshore reefs. They prefer to reside near any structure that interrupts open water, such as piles, buoys, platforms, anchored boats and flotsam. Cobia is also found in bays, inlets and mangroves.
