Froese, Rainer and Pauly, Daniel, eds. This fish is silvery in colour, the upper surface has oblique zigzagging lines while the belly is paler and spotted or marked with wavy lines. Unlike the King and Spanish species, Northern Atlantic mackerel are very low in mercury, and can be eaten at least twice a week according to United States Environmental Protection Agency guidelines.[10][11]. Atlantic Chub Mackerel. In 2007 a specimen of Atlantic chub mackerel (Scomber colias Gmelin, 1789) was caught in the Gulf of Cadiz. Yes: Status: Least Concerned : For more information about Chub mackerel (Pacific mackerel), check out the Fish Contamination Education Collaborative. "[1], Atlantic mackerel outer meat is red meat while inner meat is white, with a strong taste desirable to some consumers. Spaced only about the diameter of a single fish's mouth apart, this formation greatly reduces the ability of plankton to evade capture, as a plankton darting out of the way of one fish is likely to end up in the jaws of another. They are epipelagic to mesopelagic over the continental slope. The lengths of the fish were measured using all three methods: TL, PTL and FL, to the nearest mm-size-classes (rounded down). It swims using short movements of the rear of its body and the caudal fin. The fish releases its own oil into the salt packing and acquires a very long shelf life. Scomber vulgaris Fleming, 1828 They first come in to land in North America in April at the southern end of their range, but are found along the coast through their entire range by July. Scomber glauciscus Pallas, 1814 Learn more about what makes a few individual species unique, below. They are largely incapable of swimming, instead floating with the current. It was originally thought to be a subspecies of the chub mackerel Scomber japonicus colias. Warm water; eastern and western coasts, including the Mediterranean and southern Black Sea. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. At 37 cm (15 in), 90% of fish are capable of reproduction. [2], The Atlantic mackerel's native range in the western Atlantic extends from Labrador, Canada to Cape Lookout, North Carolina. Genetic differences only start to appear at the transatlantic scale, a fact supported by a lack of migration between western and eastern Atlantic populations, whereas eastern Atlantic stocks are known to converge in certain locations like the Norwegian Sea and North Sea. Chub Mackerel (Pacific Mackerel) Fishing. The most recent (2000-2005) large specimens caught are 50-55 cm in length compared to a maximum size of 70 cm found in earlier years. While swimming in large schools, mackerel-like fish confuse their predators with the silver-like brilliance from their scales. Atlantic chub mackerel (Scomber colias) is found throughout the warm and temperate coastal waters in the Atlantic Ocean, ... Pairs of otoliths from 50 randomly selected fish (ranging in size from 26.4 cm TL to 38.4 cm TL) were used. cm [2] It is differentiated from its congeners in a number of ways, the first being the absence of a swim bladder. Chub mackerel are easy to catch and much of what we wrote in our Spanish mackerel guide applies to this fish. Largest Size: Known to reach 25 inches: Lifespan: 11 years: Safe to Eat? [6] There are three stocks in the eastern Atlantic: one in the south, one in the west, and another in the North Sea. In 1999, Collette established, on molecular and morphological considerations, that these are separate species. Two variants are distinguished: in the late summer and autumn, the fish is fat and roe-filled, whereas in the late winter and spring it is very lean, almost emaciated. This species is known to travel great distances through the open ocean. Prices and download plans . [7], The Atlantic mackerel is an active, fast-moving fish that must keep in constant motion to bring in enough oxygen to survive. S. colias is caught by a small and coastal purse-seine fleet that traditionally operates around the islands. Atlantic chub mackerel can be found in the the Mediterranean Sea, the Black Sea, and the Atlantic Ocean. In most species, the mackerel is known to travel in large schools. Though some fish are sexually mature at 25 cm (9.8 in) in length, even by 34 cm (13 in) only about half of females will be ready to reproduce. The second dorsal fin is typically followed by 5 dorsal finlets, though it can have 4 or 6. It averages about 30 cm (12 inches) in length and is blue-green above and silver-white below, with a series of … Unlike other mackerel, Atlantic mackerel do not leap out of the water unless attempting to escape a predator. The pelagic chub mackerel, Scomber colias Gmelin, 1789 is one of the most important fishery resources in the Madeira Archipelago. UK minimum size: N/a UK shore caught record: 1lb 15oz IUCN Status Global: LC (Least Concern) Europe: LC (Least Concern) Distribution: Widespread … Continue reading → The Mackerel War. [1] In the western Atlantic there are two stocks, one in the north and one in the south,[7] for which assessments are, according to the IUCN, "highly uncertain. It possesses two spiny dorsal fins, which are spaced far apart, two pectoral fins, and small caudal and anal fins, also spaced far apart. [8], Sexual maturity is reached at around 2 years of age, though some fish may reproduce a season earlier or a season later. [5] Its body is steel-blue dorsally with wavy black lines running perpendicular to the fish's length. They are at the limit of their distribution in British waters but can be found around the southern and western regions of England as well as parts of the English Channel, Welsh coast and around the southern coastlines of the Republic of Ireland. Mackerel are smaller with shorter lifecycles than their close relatives, the tuna, which are also members of the same family. The fish is extremely high in oil content, vitamin B6, vitamin B12, selenium, niacin,[9] and omega 3, a class of fatty acids, containing nearly twice as much of the latter per unit weight as salmon. Scomber punctatus Couch, 1849 Its abundance and extensive range combined with a cyclical increase/decrease in catch mean that it is not currently in danger of going extinct. Scales are also small, with the exceptions of those immediately posterior to the head and around the pectoral fins. The origin of the anal fin is directly below or just behind the origin of the second dorsal fin. Eggs are anywhere from 1.0–1.3 mm (0.039–0.051 in) in size, trending towards smaller as the spawning season goes on. There are two populations in the Mediterranean, one in the east and one in the west. [3], In the eastern Atlantic Ocean there are three stocks differentiated by location and time at which spawning occurs, but studies have not found any distinct genetic differences between these populations. There are about 30 different fish species with the common name “Mackerel” and many of them are commercially important. The two dorsal fins are large and spaced far apart. Its maximum published weight is 3.4 kg (7.5 lb). Scomber vernalis Mitchill, 1815 Replaced by Scomber japonicus in the Indo-Pacific. The Atlantic chub mackerel Scomber colias (Gmelin, 1789) is one of the main fisheries resources in Tunisian waters. Nearly 1 million tonnes of Atlantic mackerel are caught each year globally, the bulk of which is sold fresh, frozen, smoked, or canned. [8], When feeding on larger prey, schools tend to break down into shoals and individuals find food on their own. Life and Marine Sciences 29: 43-51. Juveniles reach sexual maturity at around 2 years of age and can live to be 17.

Global annual catch is typically in the range of 1 million tonnes, though a 50% spike in 2014 put this number at nearly 1.5 million tonnes.
Chub mackerel definition, a small mackerel, Scomber japonicus, of Atlantic and Pacific seas and parts of the Indian Ocean. Typical size for a mature fish is 30 cm (0.98 ft), but individuals have been caught as large as 60 cm (2.0 ft). Landings went from almost zero to 5m pounds within the year. This information also shows that the size of Atlantic mackerel is decreasing, probably due to fishing pressure. The fish's body tapers to a slim caudal peduncle, the end of the fish to which the short but broad tail fin is attached. Schools are generally segregated by size and may include various bonitos, clupeids, and jacks. [5] They form large schools, consisting of individuals of the same relative size, near the ocean surface during all seasons but winter.

A single female can spawn as many as 450,000 eggs in a spawning season. In 2007 a specimen of Atlantic chub mackerel (Scomber colias Gmelin, 1789) was caught in the Gulf of Cadiz. It spends the warmer months close to shore and near the ocean surface, appearing along the coast in spring and departing with the arrival of colder weather in the fall and winter months. They range in size from 8 in. When consuming plankton, however, Atlantic mackerel form tight aggregations, open their mouths as wide as possible, and extend their operculums, swimming in a tightly-packed school that acts like a series of miniature tow nets. This medium-sized pelagic fish species occurs in deeper waters during the colder part of the year and near coastal waters in warmer temperatures where they spawn and feed. In the eastern Atlantic, it can be found from Iceland and Norway to as far south as Mauritania. The pelagic chub mackerel, Scomber colias Gmelin, 1789 is one of the most important fishery resources in the Madeira Archipelago. This information also shows that the size of Atlantic mackerel is decreasing, probably due to fishing pressure. The same evening it is very briefly seared over a fire and then served with lemon juice. 2.2. Larvae are 3 mm (0.12 in) when they hatch and feed on the yolk sac for about 5 days. During the post-larval stage, which occurs over the next 40 days and during which the fish reaches 50 mm (2.0 in) in length, it swims to the surface at night and down to deeper waters during the day. Arquipelago. Atlantic chub mackerel Atlantic chub mackerel, also known as Tinker mackerel, is a pelagic schooling species of mackerel found in the Atlantic Ocean, the Mediterranean Sea, and the Black Sea. Scombrini, the true mackerels. This species is found around the Atlantic coasts of France, Spain and Portugal with their distribution continuing along the western coast of Africa. They start moving back out to sea again in September and are completely gone from the coast by December. Chub mackerel, Scomber colias, is widely distributed in the warm waters of the Atlantic Ocean including the Mediterranean and Adriatic Seas. The most recent (2000-2005) large specimens caught are 50-55 cm in length compared to a maximum size of 70 cm found in earlier years. The United Kingdom and Norway bring in the most Atlantic mackerel, with annual catches coming in at over 166,000 tonnes and 160,000 tonnes respectively. It swims using short movements of the rear of its body and the caudal fin. [8] An Atlantic mackerel can live for up to 17 years and attain a length of 60 cm (24 in) and a weight of 3.4 kg (7.5 lb). The Atlantic mackerel was first described in 1758 by Swedish zoologist Carl Linnaeus in his 10th edition of Systema Naturae. In the fall and winter they move farther out and farther south to the warmer waters on the edge of the continental shelf. The Atlantic mackerel is an active, fast-moving fish that must keep in constant motion to bring in enough oxygen to survive. The rest of its body is silvery-white to yellow and may have darker splotches. The Atlantic mackerel (Scomber scombrus), also known as Boston mackerel, Norwegian mackerel, Scottish mackerel or just mackerel, is a species of mackerel found in the temperate waters of the Mediterranean Sea, the Black Sea, and the northern Atlantic Ocean, where it is extremely common and occurs in huge shoals in the pelagic zone down to about 200 m (660 ft). The IUCN did recommend careful monitoring, however, especially as the effects of climate change may impact population size and distribution. Atlantic chub mackerel is one of the most … The common mackerel (Scomber scombrus) of the Atlantic Ocean is an abundant and economically important species that is sometimes found in huge schools. Other differences include the chub’s dorsal fins are closer together, and they have only 9 or 10 spines in their first dorsal fin compared to 11 or more in the Atlantic mackerel. [7], Like other mackerels, reproduction in the Atlantic mackerel is oviparous. The eyes are large and covered by an adipose eyelid, while the teeth are small, sharp, and conical. [7] The Atlantic mackerel's common depth range extends from the surface to 200 m (660 ft), but individuals can be found as deep as 1,000 m (3,300 ft). In the European Union this size is 18 cm (7.1 in), Ukraine 15 cm (5.9 in), Turkey 20 cm (7.9 in), Romania 23 cm (9.1 in),[1] and Canada 26.4 cm. The Greek names for the two forms are koliós and tsíros, respectively. Mackerel Scomber Japonicus like to swim around and migrate in large school just like Atlantic Mackerel. In the islands of the Aegean, it is a particularly popular delicacy, under the name goúna: fresh-caught mackerel is split open at the belly, eviscerated, and left to dry flesh-side up in the sun for one day. Monthly Linnaeus gave it the scientific name Scomber scomber from the Greek word skombros meaning "tunny" or "mackerel." Mackerel are pelagic fish that live in large schools. A highly commercial species, the Atlantic mackerel is sought after for its meat, which is strong in flavor and high in oil content and omega-3 fatty acids among other nutrients. 4-6 dorsal finlets and 5 anal finlets are typical among members of this species. They are sold fresh, frozen, smoked, salted, filleted, or as steaks. The Atlantic horse mackerel (Trachurus trachurus), also known as the European horse mackerel or common scad, is a species of jack mackerel in the family Carangidae, the jacks, pompanos and trevallies. The Atlantic Chub Mackerel is a coastal schooling species found from the surface to depths up to 305 m (1,000 feet). At the end of the post-larval stage, juveniles resemble an adult mackerel in all but size. [3], Atlantic chub mackerel and other members of the genus Auxis are important pelagic forage species.[2]. Samples comprised 124 individuals with TL between 104 and 379 mm. to 24 in. [2] Its preferred water temperature is above 8 °C (46 °F), but Atlantic mackerel are common in waters as cold as 7 °C (45 °F) and have been found, albeit rarely, in 4.5 °C (40.1 °F) waters. The Atlantic chub mackerel (Scomber colias Gmelin, 1789) is a pelagic fish distributed in warm and temperate waters of the Atlantic Ocean and in the Mediterranean Sea across the shelf and upper slope. This fish is particularly abundant in the eastern Mediterranean. Time to hatching is dependent on the water temperature, and ranges from 2 days at 21 °C (70 °F) to 8.5 days at 10 °C (50 °F). long and weigh between 1 and 7.5 lbs. Scomber scomber Linnaeus, 1758 Until recently, Atlantic chub mackerel and Indo-Pacific chub mackerel were thought to be subspecies of the same species. Spawning occurs day or night in the spring and summer months, primarily within 48 km (30 mi) of shore, though it can occur as far out as 130 km (81 mi). This fish is silvery in colour, the upper surface has oblique zigzagging lines while the belly is paler and spotted or marked with wavy lines. Since … [1], 10.2305/IUCN.UK.2011-2.RLTS.T170357A6767497.en, https://en.wikipedia.org/w/index.php?title=Atlantic_chub_mackerel&oldid=987220465, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 November 2020, at 17:53. [1] Its latitudinal range is 70°N-25°N and its longitudinal range is 77°W-42°E. The anal fin, which originates slightly behind the second dorsal fin, is similar to it in size and shape and is also succeeded by 5 finlets. The stock size of chub mackerel (Scomber japonicus) in the East China Sea and the Japan/East Sea has shown a continuous decrease, with fluctuations, from 1975 to 1990. [2], Atlantic mackerel are migratory fish, spending the spring and summer closer to shore about 32–161 km (20–100 mi) out, with juveniles moving closer in to shore than adults. Its specific name was later changed to scombrus by B. Left otoliths were embedded in molds using Epoxicure resin. Most eggs are spawned in waters 9–12 °C (48–54 °F) in temperature, and as such the majority of eggs hatch in about a week. The fish's body tapers down its length, ending with a large tail fin. Despite its commercial status, the Atlantic mackerel was assessed to be of Least Concern by the IUCN in 2011. Following revisionary work by Collette (1999) and Collette et al. Because larger fish have a greater ratio of muscle mass to surface area, schools of larger fish are able to swim more quickly than schools made up of smaller individuals.
