Lingcod: Everything you need to know about Ophiodon elongatus

What is Lingcod?

Lingcod, or Ophiodon elongatus, is a prized game fish found in the North Pacific Ocean. From Alaska to California and beyond, they are an essential component of both commercial and recreational fishing communities as their white flesh possesses exceptional flavour. This blog post will uncover their incredible traits, from taxonomy and morphology to diet and reproduction. You’ll also learn about where they prefer to live and the fisheries regulations for capturing them.

Taxonomy

Lingcod is a member of the Hexagrammidae family, home to rockfish, greenlings, and other cod-like creatures. Due to its lengthy sharp teeth, this particular species has been given sole control over its own genus—Ophiodon meaning “snake-tooth” in Greek. Its Latin species name elongatus translates as “elongated” which speaks volumes about this fish’s slender body shape.

Morphology

Boasting an impressive size of up to 1.5 meters in length and 60 kilograms in weight, the Lingcod is a powerful predatory fish that inhabits coastal waters. Its body is cylindrical with small scales and its coloration varies from mottled brown or greenish-gray on its back and sides to white or cream-coloured on its belly. It has an angular head complete with a wide mouth filled with sharp teeth, as well as rounded fins – save for the dorsal fin which sports spines like daggers.

Why is Lingcod meat blue?

The deep blue hue of Lingcod is truly one-of-a-kind, derived from its high levels of melanin – the same pigment found in human skin and hair. This exquisite seafood delicacy is treasured around the world for its mild flavour and firm texture that add a unique flair to any dish or presentation. While it may not yet be as well known by many consumers compared to other fish species, this hidden gem boasts an abundance of flavour and versatility!

Distribution and Habitat

From Alaska to California, Lingcod can be found traversing the pristine waters of our North Pacific Coast. This species resides in rocky reefs and kelp forests ranging from intertidal shallows down to 300 meters deep, where they take advantage of powerful currents and turbulent waves for hunting prey and seeking refuge from predators.

Diet

The Lingcod is a ferocious predator, whose diet consists of an array of fish and invertebrates such as rockfish, greenling, herring, sand lance, squid, octopus and crabs. This voracious species has the capability to seize its prey with sharp teeth and powerful jaws before swallowing it whole. It’s even known for scavenging on dead or injured fish in addition to cannibalizing smaller lingcod.

Reproduction

With the ability to live for up to 20 years, Lingcod is a slow-growing species that may take 3-5 years before reaching sexual maturity. The spawning season commences in December and continues until March when mature females lay their eggs on rocky substrates, which are then fertilized externally by males. Once hatched within a few weeks, the larvae will drift among plankton in the water column for several more weeks until eventually settling down at bottom of aquatic habitats.

Fisheries

Boasting delicious, high-quality meat and impressive size, lingcod is a profitable species sought after by both commercial and recreational fishers. To guarantee its continued sustainability for years to come, harvest quotas are set in place for those fishing commercially while bag limits and size restrictions have been established for recreational anglers.

How to catch Lingcod?

To successfully catch lingcod, anglers can employ trolling, jigging or bait fishing tactics. Utilizing weighted lines and lures that resemble small fish will give you the best results when trolling – whilst heavy vertical jigs should be used for optimum success with jigging. Bait fishing requires sardines or sand shrimp to be cast close to rocky outcrops or kelp beds where these remarkable creatures are often sighted. Whenever harvesting this species of cod, it is essential to consider any applicable state regulations so conservation efforts remain intact.

How to fillet lingcod?

Filleting a lingcod can be achieved with ease. Begin by securely positioning the fish on a cutting board and cut off its head using an especially sharp filleting knife, being cautious to not allow it to slip through your hands in the process. Carefully slice down its body lengthwise, ensuring you don’t get too close to the rib cage as that will make detaching them later more complicated.

After cutting the fish open, use your fingers to gently tug apart any flesh still attached to the bone. If needed, employ a knife for areas where there is more resistance so that all meat separates from both sides of the spine. Once done, flip over and scrape away any last rib bones before disposing of them with the head.

Is Lingcod good to eat?

Lingcod is an incredibly nutrient-rich fish, containing a wealth of essential vitamins and minerals. Not only does it boast 18 calories, 4g of protein and 0.1g of fat per ounce (28.35g) when cooked, but it also has measurably high selenium content (9mcg/ounce), phosphorus levels (76mg/ounce), vitamin D, calcium magnesium and zinc – all while being significantly low in mercury compared to other seafood species.

How to cook lingcod?

Lingcod can be cooked in a variety of ways. It is commonly steamed, pan-fried, deep-fried or grilled. For steaming, place lingcod fillets in a steamer basket and cook for 8-10 minutes until flaky. For pan-frying, season the fish with your choice of herbs and spices and add oil to a hot skillet. Place the fish in the skillet and cook for 6 minutes per side. For deep-frying, heat at least 2 inches of oil in a pot or deep fryer to 375°F (190°C). Dip the fish into the batter and carefully drop it into the oil. Fry for 3-4 minutes until golden brown. Lastly, if grilling your lingcod, coat it with your favourite sauce or marinade and cook over medium heat on a well-oiled grill for 4 minutes per side.

Conclusion

Lingcod are a remarkable fish species with interesting anatomical features, habitats, diets and reproductive behaviours. To protect this vital North Pacific fishery resource for future generations, both commercial and recreational lingcod fisheries require careful monitoring to guarantee sustainable exploitation and conservation efforts. An in-depth grasp of the biology and ecology of lingcod is essential for successful management as well as preservation initiatives.
