Chub mackerel are easy to catch and much of what we wrote in our Spanish mackerel guide applies to this fish. The fish releases its own oil into the salt packing and acquires a very long shelf life. They form large schools, consisting of individuals of the same relative size, near the ocean surface during all seasons but winter. Larvae are 3 mm (0.12 in) when they hatch and feed on the yolk sac for about 5 days. Atlantic horse mackerel (trachurus trachurus) Morphology: a species of jack mackerel of the Carangidae family, it is a blue fish found throughout the North Atlantic.

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 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. Atlantic chub mackerel (Scomber colias) spawning season, size and age at first maturity in Madeira waters. The same evening it is very briefly seared over a fire and then served with lemon juice. They are largely incapable of swimming, instead floating with the current. Schooling behavior occurs around this time. Food availability increases greatly during the summer, and fish reach a peak for fat tissue in August, a mere four months after their lowest point in April. The pelagic chub mackerel, Scomber colias Gmelin, 1789 is one of the most important fishery resources in the Madeira Archipelago. The Greek names for the two forms are koliós and tsíros, respectively. Until recently, Atlantic chub mackerel and Indo-Pacific chub mackerel were thought to be subspecies of the same species.

Warm water; eastern and western coasts, including the Mediterranean and southern Black Sea. 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. The rest of its body is silvery-white to yellow and may have darker splotches. Copepods make up the majority of the Atlantic mackerel's diet, Calanus finmarchicus being the most abundant.

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. Despite its commercial status, the Atlantic mackerel was assessed to be of Least Concern by the IUCN in 2011. The origin of the anal fin is directly below or just behind the origin of the second dorsal fin. 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. The first dorsal fin has 9 or 10 spines and is separated from the second dorsal fin by a space at least as long as its base. [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. Arquipelago. 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. Because of its wide distribution, the Atlantic mackerel was independently described 6 more times by 5 different scientists between 1814 and 1863. 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.

[2], The Atlantic mackerel's native range in the western Atlantic extends from Labrador, Canada to Cape Lookout, North Carolina. 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). They start moving back out to sea again in September and are completely gone from the coast by December. During the larval stage, which lasts about a month, larvae grow to 10 mm (0.39 in) in length. Samples comprised 124 individuals with TL between 104 and 379 mm. 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.

Mackerel are smaller with shorter lifecycles than their close relatives, the tuna, which are also members of the same family. 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. This information also shows that the size of Atlantic mackerel is decreasing, probably due to fishing pressure. 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. Occasionally, fish will even enter harbors, and those that do are usually juveniles. The maximum published weight is 3.4 kg (7.5 lb).
