Allogastrocotyle bivaginalis is a species of monogenean flatworm, which is parasitic on the gills of a marine fish. It belongs to the family Gastrocotylidae. [1]
The species was described and illustrated from two specimens from the gills the rough scad Trachurus lathami (Carangidae) off Venezuela, and designated as the type species of the genus. [1]
In 2019, Bouguerche et al. examined specimens of monogeneans similar to Allogastrocotyle bivaginalis, collected from the gills of the Blue jack mackerel Trachurus picturatus (Carangidae) from off the Algerian coast, Mediterranean Sea. They claimed that they could not distinguish the Mediterranean specimens from A. bivaginalis, neither on the base of morphology nor on molecules (because molecular information was lacking on A. bivaginalis from Venezuela). [2]

The species' name refers to the presence of two vaginal openings. [1]
The type-host is the rough scad Trachurus lathami (Carangidae). The type-locality is off Venezuela. [1] The species is also present in the Mediterranean Sea, on another host, the Blue jack mackerel Trachurus picturatus . [2]
Horse mackerel is a vague vernacular term for a range of species of fish throughout the English-speaking world. It is commonly applied to pelagic fishes, especially of the Carangidae family, most commonly those of the genera Trachurus or Caranx. Species known as "horse mackerel" in one English dialect or another include:
The Carangidae are a family of ray-finned fish which includes the jacks, pompanos, jack mackerels, runners, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes.
The Atlantic horse mackerel, 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. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. It is an important species in commercial fisheries and is listed as a Vulnerable species on The IUCN Red List of Threatened Species.
The Pacific jack mackerel, also known as the Californian jack mackerel or simply jack mackerel, is an abundant species of pelagic marine fish in the jack family, Carangidae. The species is distributed along the western coast of North America, ranging from Alaska in the north to the Gulf of California in the south, inhabiting both offshore and inshore environments. The Pacific jack mackerel is a moderately large fish, growing to a maximum recorded length of 81 cm, although commonly seen below 55 cm. It is very similar in appearance to other members of its genus, Trachurus, especially Trachurus murphyi, which was once thought to be a subspecies of T. symmetricus, and inhabits waters further south. Pacific jack mackerel travel in large schools, ranging up to 600 miles offshore and to depths of 400 m, generally moving through the upper part of the water column.
Jack mackerels or saurels are marine fish in the genus Trachurus of the family Carangidae. The name of the genus derives from the Greek words trachys ("rough") and oura ("tail"). Some species, such as T. murphyi, are harvested in purse seine nets, and overfishing has sometimes occurred.
The shrimp scad, is a species of widespread tropical marine fish of the jack family, Carangidae. The shrimp scad is widely distributed in the tropical and subtropical western Indian Ocean and areas of the eastern Pacific Ocean, ranging from South Africa in the west to Hawaii in the east, including Japan and Australia to the north and south. The species is commonly found on inshore reefs and sandy substrates. It has the common body profile of a scad, and may be difficult to differentiate from others in the genus Alepes. It is one of the larger scads, growing to 40 cm, but often is encountered at much smaller sizes. The shrimp scad often forms large schools, and is carnivorous, consuming a variety of crustaceans and small fish. It is of moderate importance to fisheries throughout its range.
Alepes is a genus containing five extant species of tropical marine fishes in the jack family, Carangidae. They are commonly known as scads, a term applied to many genera of carangid fishes. Their body form, however, differs from these other scads by being much more ovate in shape, more similar to the larger jacks taken as game fish, although scads are generally much smaller. They are found in coastal waters throughout the Indo-West Pacific region.
The mackerel scad, or speedo, is a species of fish of the family, Carangidae. While mackerel scad can be considered gamefish, they are usually used as bait. However, they are popular eating fish in the Hawaiian islands, where they are called `opelu.
The false scad, also known as the spotfin scad, ten-finned horse mackerel and yellow horse mackerel, is a species of medium-sized marine fish classified in the jack family Carangidae. The false scad is distributed throughout the tropical and temperate waters of the eastern Atlantic Ocean from Namibia in the south to Spain and throughout most of the Mediterranean in the north. The species has an atypical body form compared to other species of Caranx, and can be distinguished from these on its elongate 'scad-like' body shape alone. Distinguishing the species from members of Decapterus and Trachurus is more difficult, requiring detailed anatomical analysis. The false scad is known to grow to a length of 60 cm and a weight of 1 kg. The species lives both pelagically and demersally in continental shelf waters, ranging from depths of 15 to 200 m. It is a predatory fish, taking small fishes, crustaceans including euphausiids and shrimps, and cephalopods as its main prey, with significant dietary shifts as it ages. The false scad reaches sexual maturity at 2 years of age, with spawning occurring between April and July in shallow inshore waters, where the juveniles remain. The species is of major importance to fisheries throughout its range, but particularly from Morocco to Senegal, with annual catches ranging from 500 to 19000 t. The species is caught using trawls, seine nets and gill nets and sold fresh, frozen or salted.
The Mediterranean horse mackerel, also known as the Black Sea horse mackerel, horse mackerel, Mediterranean scad, common scad, or simply scad, is a species of mackerel in the family Carangidae found in the eastern Atlantic from Bay of Biscay to Mauritania, including the Mediterranean Sea. It is a benthopelagic, subtropical, marine fish that can reach up to 60 cm (24 in) in length. In the countries near the Mediterranean and Black Seas, it makes up a significant portion of fish catch, 54% of fish caught in the latter. Despite overfishing in the 1980s, catch numbers have leveled out and it is listed as least concern by the International Union for the Conservation of Nature.
The blue jack mackerel is a species of mackerel-like fish in the family Carangidae. Their maximum reported length is 60 cm, with a common length of 25 cm. They are coastal fish found at depths to 370 m off the Bay of Biscay to south Morocco and the western Mediterranean.
Trachurus lathami is a species of fish in the family Carangidae and the genus Trachurus, the jack mackerels. Common names include rough scad and horse mackerel in English, as well as chinchard frappeur (French), chicharro garretón (Spanish), jurel, and carapau, garaçuma, surel, and xixarro. It is native to parts of the western Atlantic Ocean, including seas off the eastern coasts of North and South America and the Gulf of Mexico.
