Introduction
Haddock is a popular cold-water flatfish found in Northern Atlantic and Arctic waters. It belongs to the Gadidae family, alongside cod, haddock and whiting and is a commercially important species in Europe, both as a wild and farmed fish. Outside of Europe, you can find it in the Atlantic, Pacific and Arctic oceans. It is a white-fleshed fish that is easy to cook and often served as an alternative to cod or other white fish. It has a mild flavour and is relatively low in calories.
Description
Haddocks can reach a maximum length of about 40 inches (101 cm) and live up to 18 years. They are identifiable by their white flesh and black lateral line and are commonly found in depths of 30 to 200 meters and prefer habitats with sea bed composition composed of fine gravel, sand, and mud. Their diet consists of small crustaceans, molluscs, annelids, and worms.
Physical Characteristics
Haddock is mainly found in the cold-temperate waters of the North Atlantic Ocean, ranging from Iceland to the English Channel. It prefers to inhabit deeper waters beyond the continental shelf and can be found around the coasts of Iceland, Norway, Scotland, Ireland, France, Spain and Scandinavia. Physically, haddock has a silver-grey body with three distinct black stripes running along its back from its head to its tail. It is a relatively small fish, with an average length of 20-30 cm, but it can reach up to 60 cm.
Haddock are easily identifiable by their silver-green backs, white bellies, and a black thumbprint near the pectoral fin. Elongated, smoked-fish-like shape, sharp spiny fins, and single chin barbel characterise this species. The average haddock ranges from 6 to 8 inches in length and can grow up to 15 inches for larger adults. Their bodies have a smooth, slimy texture covered with large, pearl-like scales and a dark line running along the sides of their bodies.
The head of the haddock has a large, slightly oblong mouth lined with a black and white checkered pattern. These species have two sharp, protruding canine teeth near their lower jaws and two whisker-like barbels. They also have a 2-4 inch long dorsal fin, an anal fin, pectoral fins, and ventrals.
Habitat and Feeding
Haddocks are most common in coastal waters ranging from 15-90 meters in depth and prefer temperatures between 40-90 degrees Fahrenheit. As for food sources, haddock feeds on molluscs, crustaceans, fish, and worms on the ocean floor.
Fisheries and Uses
Haddock has been sustainably fished and farmed for decades and is plentiful in the wild. It is an essential commercial fish in many countries and is often used for food, bait, and pet food. Haddock is a popular choice in many dishes and has a distinct flavour that stands alone when cooked or served with other ingredients. It can be prepared in many ways, from baked and poached to fried, smoked haddock, and grilled haddock.
Haddock is especially popular in eastern European countries as a food source. It can be prepared in a variety of techniques, such as by pan-frying, baking, smoking and deep-frying, and is often served in dishes such as chowders, sandwiches, fish cakes, fish pies and curries. As a source of lean animal protein, haddock is also popular among individuals looking for nutritious protein sources.
Population and Conservation
Due to its commercial importance, haddock is managed for sustainable fishing. East coast haddocks are managed through the US/Canada Atlantic Fisheries Management Plan, and the European Unions Common Fisheries Policy governs North Sea haddocks. Through these plans, harvesting of the species is regulated to ensure the long-term health of the stock, as well as the implementation of measures to reduce bycatch.
In recent decades, the haddock population has been under threat due to climate change and overfishing. As such, various conservation efforts have been implemented to protect the haddock population, including catch limits and regulations. Despite these efforts, haddock populations remain precarious, with much of the research currently devoted towards understanding how climate change and fishing practices influence haddock species.
Distribution of Haddock Stocks
Haddock is predominantly found in the North Sea, with most continental shelf landings belonging to Scotland, England, and Iceland. It is also found in waters around Ireland, Norway, the UK and other areas of the North-east Atlantic region. Scottish haddock and other varieties can quickly replenish fish stocks, making it a viable species to fish sustainably.
In 2019, a study conducted by the ICES Journal of Marine Science confirmed that haddock stocks in the North Sea were healthy and could be sustainably exploited. This research paper recommended that haddock fishing be managed to prevent overfishing and preserve ecological thresholds.
Conservation Status
Haddocks are listed as not threatened on the IUCN Red List. While their population is stable, haddock are listed as a vulnerable species and are subject to conservation measures set by the European Unions Common Fisheries Policy. Increasing exploitation, habitat destruction and climate change are all potential threats to the haddock population. For this reason, sustainable practices are enforced by the EU, which has capped the number of haddocks able to be fished at 1.2 million tonnes.
Sustainable Fishing Practices
Sustainable haddock farming involves employing various sustainable fishing practices and best practices for haddock conservation. These practices are specially designed to ensure haddock stocks remain healthy and resilient.
Examples of sustainable fishing practices include minimising bycatch and habitat disruption, using closed containment aquaculture systems to reduce escapees, utilising selective trapping, holding, and tagging techniques to minimise impact on wild fish stocks, employing techniques like polyculture and integrating other fish species in rearing systems to mitigate health risks and reduce competition for food.
Most fisheries also implement rotational or seasonal harvesting, or time-limited protection practices like seasonal closures and habitat guard zones, utilising selective harvesting and stocking practices to maintain genetic diversity and promote robust wild populations, replacing bottom trawls and dredges with more selective equipment, enacting fleet management systems, such as day at-sea restrictions and catch/effort quotas, embracing particular harvest methods such as small mesh sizes and release of undersize fish, utilising biodiversity conservation strategies like early growth harvesting, and employing best environmental fish farming practices and green aquaculture principles.
Sustainable haddock fishing practices are essential for the health of haddock populations and for conserving wild-caught haddock. Through careful management and fishing practices, haddock remains a popular and sustainable fish for enjoyable, healthy meals.
Haddock’s Diet
Haddocks are bottom-dwelling feeders and mainly feed on crustaceans, small fish, and other aquatic organisms, such as amphipods, sea fleas, mysids, shrimp, and squid. They use their senses of smell and taste to detect prey and eat copepods, small fish, zooplankton, and on occasion, even algae or diatoms. Juveniles inhabiting shallow coastal waters mainly feed on planktonic crustaceans, copepods, and larval stages of other species.
Nearshore, haddock feed primarily on crustaceans and worms, while offshore, their diet changes to include a broader range of benthic invertebrates and fish. With such a varied menu, it’s no surprise that haddock is a popular food source for commercial fisheries and recreational anglers. Haddocks are usually fished during the colder months from December to April.
Reproduction
Haddock spawn twice a year, during spring and fall when temperatures are in the 10 to 12 degree Celsius range. Females release up to 1 million eggs, fertilised by males, and then dispersed away with currents into deeper areas. The eggs hatch after 4-5 weeks, after which the young Haddock remain in shallow water for the first few weeks of life before migrating to the deeper areas, where they can reach an age of up to ten years.
Spawning Habitats
Haddock is a highly migratory species that follow the Gulf Stream until it reaches the Atlantic shores, from Newfoundland to the Gulf of Maine. You can also find them in European waters such as the North and Baltic.
Life Cycle of Haddock
Haddock has a varied life cycle. Sexual maturity is typically reached between two to three years of age when the fish can reproduce. Reproduction is usually between April and June in the spring, when the water temperature is warm enough for the eggs to survive. Spawning sites are located in deeper offshore waters between depths of 30-80m, near the continental shelf. Haddocks form large spawning aggregations in these waters, and the female can release an average of 300,000 eggs during spawning. The eggs drift with ocean currents before hatching 24-48 hours later, at which point the haddock enter their larval stage, where they feed on plankton.
Once hatched, the juveniles spend their first few years of life in shallow coastal waters before they mature and swim to deeper ocean areas. As they grow, haddock gradually move closer to shore, feeding on molluscs, crustaceans, and worms on the sea bed. This pattern is continued throughout the remainder of their lives, usually between 8-15
Classification
Haddock is classified as Teleost fish, with a thin bony head and fins made of modified bony plates. Haddock is also a member of the Gadidae family, which is further classified as belonging to the Serranidae, Acrogenichthyes, Carboniferous, and Late Cretaceous biodiversity clades.
Haddock has a scientific name of Melanogrammus aeglefinus, and is monitored and conserved by the Marine Stewardship Council (MSC). Other members of the Gadidae family with a single chin barbell include cod, pollock, whiting, and hake.
Etymology
The etymology of the word haddock is disputed. Its origin is believed to have been derived from the Old Norse hadd, used in the 6th century, although some think it had a Dutch or English origin.
