Cobia (Rachycentron canadum)

Discover the amazing power of the Cobia fish – a ballistic predator that swims 1,500 miles!

Cobia (Rachycentron canadum), also known as black salmon, sailor’s choice, crab eater and Ling, is a species of fish found in shallow, coastal waters of the western Atlantic Ocean and Caribbean Sea. This fish is highly prized as a game fish and is sought after in both recreational and commercial fisheries. Cobia can reach lengths of up to five feet and a weight of 130 pounds. It has a long, thin body with a mottled brown, silver and black coloring that gives it a unique, distinct appearance. Its taste is sweet and mild, making it a popular choice among seafood lovers. Although often caught using hook and line, the species is subject to overfishing and is vulnerable to habitat destruction.

Cobia (Rachycentron canadum)

Cobia (Rachycentron canadum or “Seriola Canadensis”) are an economically important fish species found in tropical and temperate waters around the world. They have silver bodies with dark spots, long cylindrical bodies, and large pectoral and pelvic fins. They are considered to be a semi-pelagic fish and can swim between 20 and 40 feet deep in the water column. Cobia’s are also called ling, lemonfish, crabeaters and other regional vernacular names for the species.

Cobia are commercially fished around the world and have been for many years. It has been reported that their populations vary by region and may not be a stable species throughout its range. This fish is caught with a wide variety of fishing gear, including bottom longlines, trolling lines, purse seines, traps, and driftnets. The most common method used is the bottom longline gear. In some areas, they are considered a nuisance species because they cause damage to commercial gear operations.

Cobia are warm-water fish and are most commonly found in areas with temperatures ranging between 68 and 86 degrees Fahrenheit. They prefer to live near structure such as piers, bridges, reefs, and wrecks. This suggests that they may be reliant upon the structure for protection from predators and possible prey items. They are also found in shallow water and may move further offshore in the summer months for reproductive purposes.

Cobia have a have a varied diet. They will feed on a wide variety of fish and invertebrates including crabs, shrimp, squid, and smaller fish. They are also known to scavenge on the bottom for any food that may be available. Cobia have sharp teeth and powerful jaws, making them well-equipped to take advantage of any opportunity for food.

Cobia are prolific breeders, typically spawning in large aggregations during the spring and summer months. They reach sexual maturity at a relatively young age (2-3 years) and can live up to 15 years in the wild. They produce large quantities of eggs during spawning and the larvae are planktonic, meaning they can drift for long distances on ocean currents.

Cobia have a unique lifecycle in which the juveniles form schools and migrate long distances to distant offshore areas, which is known as the “Cobia corridor”. In these areas, the juvenile fish remain until they reach sexual maturity. This migration route allows the fish to inhabit new areas, prey upon different species, and spread the population widely. This also benefits the commercial industry, as they can more readily target fish living in multiple areas.


Cobia are considered to be a high-value commercial species, with an estimated global catch of 800,000 metric tons per year. Despite this, their populations remain relatively healthy and are not considered to be threatened or endangered. However, this species is still subject to overfishing, pollution, habitat destruction, and fishing pressure, therefore it is important to ensure that populations remain stable and do not decline.

To ensure the survival of the cobia populations, there are several measures that can be taken. Firstly, it is important to ensure that there are stock assessments conducted regularly so that the population status of the species can be monitored. Additionally, artificial reefs can be developed to provide additional habitat and structure for the fish to inhabit. Lastly, commercial fishing quotas should be managed responsibly and enforced to avoid overexploitation of the species.


Cobia are a highly sought after species for both recreational and commercial fisheries. The flesh of the fish is highly valued and is often used to make high-quality steaks. The fish is also used to make a variety of dishes, such as sushi, ceviche, and fish tacos. The liver of the cobia also has a high oil content and is used to make fish oil. Cobia is also farmed in several parts of the world, primarily in Asia.
