Lingcod (Ophiodon elongatus) is a large, predatory marine fish belonging to the family Hexagrammidae (greenlings). Despite its common name, it is not a true cod (family Gadidae) but is more closely related to greenlings and rockfishes. It is a highly sought-after sport and commercial fish known for its distinctive appearance, aggressive feeding habits, and excellent table fare. Lingcod are characterized by their elongated bodies, large mouths filled with numerous sharp teeth, and mottled coloration that provides camouflage against rocky substrates.

Tips Identifikasi
Mouth and Teeth
Look for a very large mouth armed with numerous, sharp, needle-like teeth. This is one of the most distinguishing features.
Dorsal Fin
Observe the long, continuous dorsal fin that is deeply notched, separating the spiny anterior part from the soft-rayed posterior part.
Coloration
Note the highly variable, mottled coloration (brown, grey, green, blue) with dark blotches, which helps it blend into rocky environments.
Head Shape
The head is large and broad, often with a fleshy cirrus (small flap) above each eye, though this can be less prominent in some individuals.

Fakta kunci
Voracious Predatorbehavior
Lingcod are apex predators in their rocky reef habitats, consuming almost any fish or invertebrate they can fit into their large mouths, including other lingcod.
Blue Meatinteresting
Some lingcod have striking blue or green flesh, a harmless genetic trait caused by a bile pigment called biliverdin. This color disappears when cooked.
Parental Carebehavior
Male lingcod exhibit strong parental care, guarding large egg masses (up to 500,000 eggs) laid by multiple females in rocky crevices for several weeks until they hatch.
Long-Livedrecord
Lingcod can live for over 20 years, with some individuals recorded to be over 25 years old.
Size Mattersrecord
They are one of the largest members of the greenling family, with individuals commonly reaching lengths of 90-120 cm (3-4 feet) and weights of 10-20 kg (22-44 lbs). The largest recorded lingcod was over 150 cm (5 feet) and weighed over 59 kg (130 lbs).
Informasi keamanan
Tangani dengan hati-hati- Tingkat keamanan: caution
- Berbisa: Tidak
- Kelayakan konsumsi: edible
- Catatan penanganan: Lingcod possess numerous sharp teeth and can inflict painful bites if handled carelessly. Anglers should use appropriate tools (e.g., lip grippers, gloves) to handle them safely. Their gill plates can also be sharp. While not venomous, their aggressive nature requires caution.
Spesies serupa
Cabezon
Scorpaenichthys marmoratus
Cabezon have a much broader, flatter head, a prominent fleshy flap on the snout, and a shorter, less deeply notched dorsal fin. Their coloration is also typically more marbled and less blotchy than lingcod.
Kelp Greenling
Hexagrammos decagrammus
Kelp greenlings are generally smaller, have five lateral lines (Lingcod have one), and their dorsal fin is less deeply notched. Males and females also exhibit distinct color patterns.
Rockfish species
Sebastes spp.
Rockfish typically have more robust, spiny bodies, often with venomous spines (though not all are highly venomous), and their dorsal fins are usually more distinctly separated into spiny and soft-rayed portions. Lingcod have a much more elongated body and a distinctively large mouth.
