The cusk Fish or tusk (Brosme brosme) is a North Atlantic cod-like fish in the ling family Lotidae. It is the only species in the genus Brosme. Other common names include Tusk, Torsk, European Cusk, Brosmius.[rx]
Cusk is a fish with long body of the cod family Gadidae and is found along ocean bottom in deep offshore waters on either side of the North Atlantic. Cusk fish could be found in rough, gravel, rock, and pebble bottoms. Usually, it feeds on shellfishes, crustaceans, starfishes, benthic fishes such as gurnard and flatfishes.

Having a scientific name as Brosme Brosme, this fish has an elongated body that measures 4 ft. (120 cm). Cusk fish has a small head with a downward sloping head and a flat lower jaw. The barbell could be found on the chin. It has a flat dorsal fin that runs from inline having pectoral fin to tail and also a flat anal fin running from middle of the body to tail. Both are joined narrowly to the small and rounded tail fin. The pelvic fin is mildly elongated. The curved lateral line is present in the middle. The color of cusk fish is variable most often above brownish-grey and underneath is paler. Pale dorsal or anal fins acquire a black band near margins with white rims. The specimens usually young have six transverse yellow bands on sides. The size of the cusk may grow about 3 to 3.5 feet (90 to 110 cm) long. They live in deep water having little to no ambient light. It has large eyes and is upturned for predator or prey detection. It has a lifespan of 20 years in the wild.
Life cycle
During spawning season, females could lay up to 2 million buoyant eggs at a time. Eggs hatch into planktonic young that remains in coastal and shallow-water environments till they grow to 5 centimeters long. It has a slow growth rate (on average reaches 22 centimeters by age 6 and then gains about 10 centimeters per year thereafter). When reached 50 cm long (8 to 10 years of age), they achieve sexual maturity.
Reproduction
Cusk is regarded to be polygynous and is solitary outside breeding season. Once a year, spawning occurs between April and July. The spawning grounds throughout this species range with notable areas between Scotland and Iceland, in the northern North Sea, along edges of Shetland and Faeroe Islands, and In the Gulf of Maine.
Food
It is a bottom-dwelling species, sluggish and a weak swimmer. It consumes crustaceans and other soft-bodied invertebrates or mollusks.
Geographic Range
Cusk have a range and distribution similar to that of Atlantic cod. They are found in the northwest Atlantic Ocean from New Jersey to the Strait of Belle Isle in Canada, along the coast of Newfoundland, and occasionally off the southern tip of Greenland. In the northeast Atlantic Ocean, they are found along the coasts of Iceland, Scandinavia, and northern Ireland and England, including the northern North Sea.

Habitat
Cusk are benthic fish, inhabiting rough-bottom areas in the cooler waters of the North Atlantic. Cusk are most often located over rocky, mud, or gravel bottoms and can be found over seamounts and knolls; they are rarely ever found over flat, sandy bottoms. A deep-water fish, cusk seldomly occur in water more shallow than 20-30 meters and are most commonly found at depths of 150-450 meters in the northeast Atlantic and from 18-149 meters in the northwest Atlantic. They can be found in waters as deep as 1,000 meters and in water temperatures from 0-10°C. (Bailly, 2013; Cohen, et al., 1990; Luna and Capuli, 2012; Nelson, 1994)

Physical Description
Cusk are variable in color, with their primary dorsal coloration ranging from dark grey to a rusty or greenish-brown, fading through the sides to a pale white or gray ventrally. Their vertical fins have dark margins edged in white. Adults are typically more dully-colored than juveniles, who may have six transverse yellow bands. Cusk has one long dorsal fin, one anal fin, short pectoral fins, and rounded caudal fins, as well as a chin barbel. They are easily distinguished from other members of the family Gadidae by their single dorsal fin and characteristically rounded caudal fin. Most cusks grows to be less than 100 cm in length (average 50-95 cm), with an average weight of 12 kg (maximum recorded weight 30 kg). There are no polymorphic forms or documented seasonal variations, and populations on both sides of the Atlantic are remarkably similar in size and weight, differing only slightly in color.

Development
Females release up to 2 million buoyant eggs at a time during spawning season. Eggs hatch into planktonic young, which remain in coastal, shallow-water environments until they grow to a length of about 5 centimeters, becoming benthic thereafter. These fish have a relatively slow growth rate, reaching 22 centimeters on average by age 6 and gaining about 10 centimeters per year thereafter. Sexual maturity is achieved at about 50 centimeters in length (8-10 years of age). (Cohen, et al., 1990; Shackell, et al., 2005; Tyus, 2012)
Reproduction
Little is known about cusk mating systems, but they are assumed to be similar to that of its relative, Atlantic cod (Gadus morhua). While Atlantic cod are generally more active than cusk, they do not have rigorous courtship behaviors. A male will court a female with fin displays and “grunting,” after which the female will allow the male to invert himself beneath her, where fertilization of the egg clutch occurs. Cusk are solitary outside of breeding season and are assumed to be polygynous. Spawning occurs once a year between April and July and there are spawning grounds throughout this species’ range, with some notable areas between Scotland and Iceland, along the edges of the Shetland and Faeroe Islands, in the northern North Sea, and in the Gulf of Maine. (Cohen, et al., 1990; Nelson, 1994; Tyus, 2012)
- Mating System

Breeding occurs once yearly, between April and July. Up to 2 million eggs are released and fertilized in a clutch and sexual maturity is reached at 8-10 years. (Cohen, et al., 1990; Matthews, 1927)

Lifespan/Longevity
Cusk can live for up to 20 years in the wild. As benthic fish that use primitive gas bladders for buoyancy, removal to the surface, with its related rapid change in pressure, is often immediately fatal. Commercial fishing is generally considered to be the greatest limiting factor in cusk longevity, as they are often by-catch of Atlantic halibut, cod, pollock, and haddock.

Behavior
Cusk is solitary bottom foragers and is sluggish, generally poor swimmers. Their activity levels are not regulated by diurnal patterns. They expend little or no energy in long-distance travel, instead slowly covering expanses of territory and foraging as they pass through. They have no discernible social structure and are social only during mating. (Bailly, 2013; Cohen, et al., 1990; Tyus, 2012; Wootton, 1990)

- natatorial
- diurnal
- nocturnal
- crepuscular

Home Range
Anecdotal evidence from fishing communities suggests that cusk do not have large home ranges. If cusk is found on new fishing grounds, they can be fished out of existence in that locality in a short period of time, with no replenishment. It is assumed that they migrate only in terms of depth, not range. (Cohen, et al., 1990; Matthews, 1927)
Communication and Perception
Cusk rarely communicates with each other, and when they do it is most likely in order to locate a mate. Little is known of how this communication occurs, but it likely involves chemical signaling by females. Cusk lives in deep water with little to no ambient light; their eyes are large and upturned for predator and prey detection. They have a sensory barbel on their chins that can detect vibrations, guide them over terrain, and may serve in a chemosensory capacity. They have moderately well-developed hearing and pressure sensitivity (through the lateral line system) and hunt primarily by sight, smell, or barbel detection. (Tyus, 2012; Wootton, 1990)

Food Habits
Cusks are carnivorous foragers of small fishes, crabs, and other crustaceans, mollusks, starfishes, and other small, soft-bodied, benthic invertebrates. Some examples of prey items include gurnard (Family Triglidae), pea crabs (Pinnotheres Pisum), caridean shrimp (Crangon crangon), and margarita snails (Margarites pupillus). They are likely opportunistic scavengers as well, scavenging freshly dead organisms if found. (Bailly, 2013; Cohen, et al., 1990; Matthews, 1927; Shackell, et al., 2005; Tyus, 2012)

Predation
The primary predators of adult cusk are humans; these fish share nearly identical habitats with Atlantic cod, a staple of the world’s fishing industry. In 1987, an estimated 46,254 metric tons of cusk were caught as accidental bycatch and subsequently consumed; landings, as well as the size of fish caught, have steadily decreased over the years (about 74 metric tons in U.S. waters in 2004), likely a sign of overall population decreases. Besides humans, cusk is preyed upon by sand sharks, dogfish, thorny skates, harbor seals, tuna, and porpoises. They rely on their slow movement and cryptic coloration to avoid detection by the roving predators they encounter. Additionally, the rocky substrate they inhabit allows them to seek cover in inaccessible crags if they feel threatened. (“Cusk (Brosme brosme)”, 2009; Bailly, 2013; Cohen, et al., 1990; Matthews, 1927; Nelson, 1994)
- Known Predators
- Thorny skate (Amblyraja radiata)
- Spiny dogfish (Squalus acanthias)
- Landshark (Family Odontaspididae)
- Tuna (Thunnus thynnus)
- Harbor seal (Phoca vitulina)
- Porpoise (Family Phocoenidae)
Ecosystem Roles
Cusk are predators, consuming creatures that are either omnivores, detritivores, herbivores, filter feeders, or other small opportunistic carnivores. While they are not the preferred prey for any particular species, they are nonetheless occasional prey for many benthic predators and pelagic diving predators. They may be hosts to a variety of parasites, including roundworms, flatworms, and copepods. (“A biological survey of the waters of Woods Hole and vicinity: Part II, Section IV: A catalogue of the marine flora”, 1911; Gibson, 1996; Luna and Capuli, 2012; McDonald and Margolis, 1995; Nelson, 1994; Tyus, 2012; Wootton, 1990)

Economic Importance for Humans: Positive
Cusk are a food item for humans. Because cusk and Atlantic cod are so similar in taste and appearance, they are often handled the same once caught and have the same pound for pound selling weight. This makes cusk both a valuable economic resource for fisheries and an important source of food for many individuals. (Cohen, et al., 1990; Matthews, 1927; Nelson, 1994)

Economic Importance for Humans: Negative
There are no known negative impacts of cusk on humans. (Cohen, et al., 1990; Matthews, 1927)
Conservation Status
Cusk are considered to be a threatened species by the Committee on the Status of Endangered Wildlife Species in Canada and a species of concern by the U.S. National Marine Fisheries service. Cusk have not yet been assessed by the IUCN. It is not considered a threatened species by CITES. Due to its decreasing population and usefulness as a food source it is garnering additional attention. (“Brosme Brosme”, 2012; “Cusk (Brosme brosme)”, 2009; “Recovery potential assessment for Cusk (Brosme brosme)”, 2008; Tyus, 2012; Wootton, 1990)

- Riboflavin (B2) – Contributes to your energy creation, blood health, normal vision, cell protection, and to reducing tiredness and fatigue
- May Prevent Chronic Diseases – There is an impressively large amount of selenium found in smelt fish, nearly 45% of your daily requirement in each serving. This relatively rare mineral works as a powerful antioxidant. It may reduce oxidative stress in the body and reduce the risk of developing chronic diseases. [rx]
- Prevent acne – It prevents acne and regulates testosterone levels in the body. Additionally, it is also involved in collagen synthesis. It normalizes the skin oils and promotes skin health. Zinc promotes the count of white blood cells and lowers the risk of infection. Zinc reduces the appearance of scars. (rx)
- Treat cramps – The deficiency of potassium causes cramps in muscles that is known as hypokalemia. The high intake of potassium prevents muscle cramps. and the fish is the best source of potassium.(rx)
- Provides energy – Sugar is a great source of energy. Vitamin B1 oxidizes the usable form of energy. It plays a vital role in the pyruvate dehydrogenase system that assists in sugar oxidation. Vitamin B1 is essential for the functions of the enzyme system that supports various functions. (rx)
- Enhance immunity – Vitamin B1 promotes immunity power by promoting antibodies and reinforce the defense system to counteract infections.
- Nervous health – Riboflavin cures nervous ailments such as Alzheimer’s disease, numbness, anxiety, multiple sclerosis, and epilepsy. It helps to treat painful symptoms of Carpal Tunnel Syndrome.
- Help Growth – Nowadays, a lot of parents are stimulating their children’s growth by giving them additional supplements. However, it will be better if we stimulate it naturally. Such as giving the kids balanced nutrition, one of the ways to do this is by giving them the sea fish. The contents of vitamin D in it can also help children to grow taller. The health benefits of baby banana can also be an alternative for you to help with, especially, children’s growth.
- Strengthening Body’s – Another benefit of sea fish is to protect and maintain the body’s immune system. The content of calcipotriol in vitamin D that is produced by the pomfret fish can also function as an immune system modulator. This nutrition is well-fitted for those of you who are easy to catch a cold, flu, cough, or even headache.
- Decrease the Risk of Breast Cancer – Breast cancer is one of the diseases that are very difficult to cure. Therefore, we need to take some steps in order to avoid this cancer. This can be done in many ways such as consuming the sea fish. This fish is capable to prevent cancer cells from multiplying in your body.
- Help You Stays Young – Rejuvenating skin to make it stays beautiful and elastic is certainly what every woman always hoping for. One of the tips to do this, is, by consuming foods that contain vitamin D, such as sea fish. By consuming the fish every day, then the vitamin D can help to rejuvenate your skin and makes it look healthier and fresher. Even the vitamin D2 and D3 types are capable to decrease the risk of skin diseases such as psoriasis.
- Osteomalacia Medicine – Osteomalacia is a disease that attacks the tissues of the human body. The cause of this is the abnormality function of tissue when it is processing the development of minerals on the bones. This can make the bones weak and very easy to break, which usually happens in adults. The solution to this disease is by consuming sea fish and food that have vitamin D in them as well as exposing yourself to the sunlight.
- Prevent Rachitic – If osteomalacia usually attacks the adults, rachitic is a bone disease that usually attacks the children. The main cause of this disease is lacking vitamin D and minerals in the bones, thus disturbing the development of the bones. The disease will make the bones weak and not strong enough. One of the solutions to this is to let the children consume foods with vitamin D in them such as spot fish and exposure to the sunlight as well.
- Decrease Dementia Risk – For those of you who can afford to consume fish every day, this may be a way to decrease the risk of developing dementia such as Alzheimer’s. This disease attacks the memory or storage media since it degrades the brain cells that can make the patient suffer severe memory loss. One of the ways to prevent this is by consuming fish for its omega 3 content (DHA and EPA). It can help stimulate your brain tissues and cells. If you happen to notice some symptoms of dementia within your body or people around you, don’t forget to go consume sea fish immediately.
- Decrease Depression – Consuming sea fish every day will allow you to decrease the risks of depression. This can be said since one of the causes of depression is a low level of omega 3 fatty acid. Therefore, consuming his fish every day can help you to make sure that you have the omega 3 you needed. There you go to know the health benefits of sea fish.

Recipes 1
INGREDIENTS
- ⅓ cup olive oil
- 8 to 10 scallions, trimmed (with most of the green left on), cleaned and minced (1 cup)
- 6 large garlic cloves, peeled and sliced fine (3 tablespoons)
- 2 green bell peppers, seeded and cut into 1/2-inch pieces (2 cups)
- 2 small zucchini (10 ounces), washed and cut into 1/2-inch pieces (2 cups)
- 1 ½ teaspoons salt
- ½ teaspoon freshly ground black pepper
- 6 plum tomatoes (1 pound), halved, seeded and cut into 1/2-inch pieces (2 1/2 cups)
- 6 pieces cusk, each about 1 1/2 inches thick and weighing about 6 ounces
PREPARATION
- Heat the oil until hot, but not smoking, in one or two skillets with lids. Add the scallions and garlic, and saute them for 1 minute. Then add the peppers and zucchini and saute for 1 minute.
- Add the salt, pepper, and tomato to the skillets, and mix well. Add the pieces of fish into the mixture, completely embedding them in the vegetables. Cover, reduce the heat to low and cook the fish for about 10 minutes (more or less, depending on the thickness of the fillets). The cusk should be just cooked through; overcooking tends to dry it out.
- Serve immediately with rice and cumin.

Ingredients
- 1 teaspoon butter
- 1 tablespoon olive oil
- 2 ounces Spanish chorizo, skin removed and chopped
- 1 medium sweet onion, chopped
- 1 teaspoon smoked paprika
- 1 bay leaf
- 2 sprigs fresh thyme
- 1 large Russet potato, scrubbed and cut into 1/2-inch dice
- 3 to 3 1/2 cups seafood stock
- 1 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
- 1/2 cup roasted red peppers, chopped
- 1 pound white flaky fish fillets (cod, cusk, haddock, hake, or pollock)
- 1/2 to 1 cups cream (or half-and-half, if you must)
- 2 tablespoons chopped chives (for garnish)
Recipes 3
INGREDIENTS
- 2 slices lean bacon, cut into small pieces
- 1 Tbsp unsalted butter
- 1 medium onion, cut in half-inch dice
- 3-4 sprigs of fresh thyme
- 1 bay leaf
- 1 lb potatoes, peeled and chopped in half-inch dice (Yukon Gold preferred)
- 2-3 cups strong fish stock
- salt and freshly ground black pepper
- 1½ lb skinless fish fillets (non-oily fish: haddock, cod, pollock, cusk)
- 1 cup heavy cream
INSTRUCTIONS
- Heat a 4-quart heavy pot over low heat, and add the bacon and butter. Cook the bacon slowly so that some of the fat renders, then increase heat and cook bacon until brown and crispy. Remove the bacon with a slotted spoon, leaving the fat in the pot. Reserve the bacon until later.
- Add onions, thyme, and bay leaves to the pot and cook, stirring occasionally, for 6-8 minutes, until the onions are softened and tender but not browned. Add the potatoes and stock – the stock should come right up to the top of the potatoes. If it doesn’t, add a bit of water so that they are just covered.
- Turn up the heat and bring it to a boil. Cook the potatoes for about 10 minutes, until they are just cooked through. If the stock hasn’t thickened lightly, smash a few of the potato chunks against the side of the pot and cook a minute or two longer to release their starch.
- Reduce heat to low, and season assertively with salt and pepper. Go heavy on the seasonings now, because you won’t want to stir much once the fish goes in.
- Lay the fish fillets on top of the potatoes, cover, and cook over low heat for 10 minutes, then remove the pot from the heat and let stand, covered, 10 minutes more, so that the fish cooks through completely.
- Gently stir in the cream and taste. Adjust seasonings, garnish with the reserved bacon bits, and serve promptly.
How to Eat
- It could be found fresh, dried salted, and frozen as fillets.
- Cusk fish is often consumed steamed, boiled, fried, baked, broiled, and microwaved.
- Being oilier, the meat of Cusk fish is baked and grilled.
- It is used in chowders and soups.
- It is also used in kabobs.

Precautions
- The consumption of sea fish if one is trying to reduce inflammatory diseases such as heart disease.
- Farmed ones contain arsenic that leads to arsenic poisoning.
- Seafood should be cooked safely in order to prevent foodborne illness.
- Pregnant women, young children, older adults, people having lower stomach acid and compromised immune systems (HIV/AIDS, liver disease, cancer, diabetes, gastrointestinal disorders, people taking steroids, chemotherapy, or immune system) are prone to higher risk.
- It might be contaminated with bacteria such as Vibrio parahaemolyticus, Vibrio vulnificus, and other bacteria relate to land use, sewage discharges, runoff, etc. These microorganisms occur naturally in warm coastal waters which could cause even death or serious illness in individuals who are at higher risk.
- Listeria monocytogenes could cause a serious foodborne illness known as listeriosis.
- The virus Hepatitis A could survive in light cooking. So one should consume it after being properly cooked.
- Fish could have toxins that could cause illness such as ciguatoxin and scombrotoxin, or histamine poisoning.
- Sea fish is related to Scombrotoxin (histamine) which develops when fish is not kept cold enough. The symptoms develop quickly and also disappear completely within 24 hours.
- The flesh of tropical marine fishes might cause ciguatera poisoning experiencing gastrointestinal maladies that could last for several days, weakness in arms and legs, and reversal inability to differentiate between cold and hot. The symptoms could persist for weeks.
- Farmed seafood results in to increase in inflammation leading to weight gain, arthritis, and heart diseases.
- The imbalance ratio of Omega-6 and Omega-3 causes heart disease and hypertension.
- Seafood and fish in farms have polychlorinated biphenyls (PCBs), organophosphorus (OPs), organochlorine (OC), trifluralin pesticides, and hexachlorobenzene (HCB) causing diseases or even death.
- The seafood has a high content of mercury, which may lead to mercury toxicity.
- Consume it in moderate amounts. So consume it with caution or Avoid consuming it raw.
- Some people might get allergic reactions. So avoid it.
- It has a high chance of contamination.
- One should limit its intake.
- Consult the doctor by pregnant women and children before consuming it. Children and pregnant women should avoid it because the high content of mercury might cause a negative impact on the development of the nervous system of a fetus.
