Cobia (Rachycentron canadum) — also known as black kingfish, black salmon, ling, lemonfish, crabeaters, aruan tasek, etc. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for Year 1766 ( MDCCLXVI) was a Common year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a — are perciform marine fish, the sole representative of their family, the Rachycentridae. The Perciformes, also called the Percomorphi or Acanthopteri, include about 40% of all bony Fish and are the largest order of vertebrates. Fish are aquatic Vertebrate animals that are typically ectothermic (previously Cold-blooded) covered with scales, and equipped with two

Description
Attaining a maximum length of 2 metres (78 inches) and maximum weight of 68 kilograms (150 pounds), Cobia have elongate fusiform (spindle shaped) bodies and broad, flattened heads. Their eyes are small and their lower jaw projects slightly past the upper jaw. On the jaws, tongue and roof of the mouth are bands of villiform (fibrous) teeth. Their bodies are smooth with small scales, their dark brown coloration grading to white on the belly with two darker brown horizontal bands on the flanks. These may not be prominent except during spawning when Cobia lighten in colour and adopt a more prominently striped pattern. The large pelvic fins are normally carried horizontally (rather than vertically as shown for convenience in the illustration), so that, as seen in the water they may be mistaken for a small shark. When boated, the horizontal pelvic fins enable the Cobia to remain upright so that their vigorous thrashing can make them a hazard. The first dorsal fin is composed of six to nine ,independent, short, stout, and sharp spines. The family name Rachycentridae, from the Greek words rhachis meaning "spine" and kentron meaning "sting," is an allusion to these dorsal spines. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly Mature cobia have forked, slightly lunate tail fins with most fins being a dark brown. They lack air bladders. gas bladder (also fish maw, less accurately swim bladder or air bladder) is an internal organ that contributes to the ability of a Fish
Similar Species
Cobia somewhat resemble and are most closely related to the Remora of the family Echeneidae. Remoras or suckerfish are elongate brown Fish in order Perciformes and family Echeneidae. However, they lack the dorsal sucker of the Remora, their body is far stouter and their tail is far more developed, and forked instead of rounded. Juvenile Cobia are patterned with conspicuous bands of black and white. Their tails are rounded rather than forked as in the adults.
Distribution and Habitat
Cobia are pelagic and are normally solitary except for annual spawning aggregations; however they will congregate at reefs, wrecks, harbours, buoys and other structural oases. Any water in the sea that is not close to the bottom is in the pelagic zone. In nautical terminology a reef is a rock, sandbar, or other feature lying beneath the surface of the water (six fathoms or less at low water They may also enter estuaries and mangroves in search of prey. An estuary is a semi-enclosed Coastal body of Water with one or more Rivers or Streams flowing into it and with a free connection to the open Mangroves (generally are Trees and Shrubs that grow in saline coastal habitats in the Tropics and Subtropics.
Feeding Habits
Cobia feed primarily on Crabs, squid and other fish. Crabs are decapod Crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (βραχύ / brachy Squid are marine Cephalopods of the order Teuthida, which comprises around 300 species Cobia will follow larger animals such as Sharks, Turtles and Manta Rays in hope of scavenging a meal. Sharks ( Superorder Selachimorpha) are a type of Fish with a full cartilaginous Skeleton and a highly streamlined body Turtles are Reptiles of the Order Testudines (all living turtles belong to the Crown group Chelonia) most of The manta ray ( Manta birostris) is the largest of the rays, with the largest known specimen having been more than 7 Cobia are intensely curious fish and show no fear of boats. Their predators are not well documented, but the dolphinfish (Coryphaena hippurus) is known to feed on immature Cobia. The Coryphaenidae, also called the dolphinfishes are a family of marine ray-finned Fish belonging to the Order Perciformes. Shortfin mako sharks are known to feed on adult Cobia and have been seen by fishermen following Cobia during their annual springtime migration in the northern Gulf of Mexico. The shortfin mako shark, Isurus oxyrinchus ("sharp nose" is a large Shark of the Lamnidae family The Gulf of Mexico ( Spanish: Golfo de México) is the ninth largest Body of water in the world
Life History
Cobia are pelagic spawners; that is, they release many tiny (1. 2 mm) buoyant eggs into the water which become part of the plankton. Plankton consist of any drifting Organisms ( Animals Plants Archaea, or Bacteria) that inhabit the Pelagic zone of The eggs float freely with the currents until hatching. The larvae are also planktonic, being more or less helpless during their first week until the eyes and mouths develop. Males mature at two years and females at three years. Both sexes lead moderately long lives of 15 years or more. Spawning takes place diurnally from April to September in large offshore congregations. Up to 20 individual spawns may take place in one season, with intervals of about one to two weeks. Cobia are frequently parasitized by nematodes, trematodes, cestodes, copepods and acanthocephalans. Parasitism is a type of symbiotic relationship between Organisms of different Species. The nematodes or roundworms ( Phylum Nematoda from Greek (nema "thread" + -ode "like" are one of the most common The Trematoda is a class within the phylum Platyhelminthes that contains two groups of parasitic Worms commonly referred to as flukes Tapeworm is also an older name for a type of Computer virus. Cestoda is a class of Parasitic Flatworms commonly called Copepods are a group of small Crustaceans found in the sea and nearly every freshwater habitat and they constitute the biggest source of protein in the oceans The Acanthocephala ( Greek ακανθος akanthos, thorn + κεφαλη kephale, head is a phylum of Parasitic worms known as
Migration patterns
Cobia make seasonal migrations along the coasts in search of water in their preferred temperature range. Wintering in the Gulf of Mexico, they migrate north as far as Maryland in the Summer, passing East Central Florida in March.

Fishing Gear and Methods
Cobia are powerful fish popular among sport fishermen, and a prized table fare. For the computer security term see Phishing. Fishing is the activity of catching Fish. The American shad or Atlantic shad, Alosa sapidissima, is a Species of Anadromous Fish in family Clupeidae Not to be confused with the Barramundi Cod or the Australian members of the genus Scleropages (which sometimes are referred to as Barramundis Cobia ( Rachycentron canadum) — also known as black kingfish black salmon ling lemonfish crabeaters aruan tasek, etc The Coho salmon, Oncorhynchus kisutch, (from the Russian кижуч kizhuch) is a Species of Anadromous Fish Hickory shad ( Alosa mediocris) is migratory clupeid native to the Atlantic Coast of the eastern United States The king mackerel ( Scomberomorus cavalla) is a migratory species of Mackerel that lives its entire life in the open waters of the western Atlantic Ocean The Mahimahi (in Hawaiian Coryphaena hippurus, also known as common dolphin-fish, dorado maverikos, or lampuki (in Maltese The sand whiting, Sillago ciliata, (also known as the summer whiting or blue-nose whiting) is a common species of coastal marine Fish The silver carp ( Hypophthalmichthys molitrix) is a species of Freshwater Cyprinid Fish, a variety of Asian carp native to north and Striped bass are Perciform fish found all along the Atlantic coast from Florida to Nova Scotia, and are caught as far north as Hudson Bay.

The walleye (common US name or yellow pickerel (Canada ( Sander vitreus vitreus, formerly Stizostedion vitreum vitreum) is a freshwater Perciform Game fish are Fish pursued for Sport by recreational Anglers. Recreational fishing, also called sport fishing, is Fishing for Pleasure or Competition. Cobia are primarily sought by sight casting small Chartreuse jigs to migrating fish, or to fish following Turtles or Manta rays. They are a bycatch taken by commercial fishermen trolling for King Mackerel, or by live Menhaden slow-trolled near reefs and wrecks.
Utilization
Cobia are sold commercially, and command a high price for their firm texture and excellent flavor. However, there is no directed fishery owing to their solitary nature. They have been farmed in aquaculture for this reason. Aquaculture is the farming of freshwater and saltwater organisms including Molluscs Crustaceans and aquatic plants The meat is usually sold fresh. They are typically served in the form of grilled or poached fillets. Chefs Jamie Oliver and Mario Batali each cooked several dishes made with cobia in the "Battle Cobia" episode of the Food Network program Iron Chef America, which aired in January 2008. James Trevor 'Jamie' Oliver, MBE (born 27 May 1975 frequently Nicknamed The Naked Chef, is an English Celebrity chef. Mario Batali (b September 9, 1960) is an Italian American Chef, restaurateur, TV host and Writer.
