Biology

provided by Fishbase
Inhabit rocky or hard bottom and is a voracious eater. Food includes crustaceans, mollusks, sea urchins, fishes such as herring, sand lance and silver hake, and any bottom invertebrates that are available. When taken out of the water the belly becomes inflated so that when returned to the water they are unable to submerge. Adults attach their eggs near the base of a sponge to use as a spawning bed (Ref. 34819, 41075).

Hemitripterus americanus

provided by wikipedia EN

Hemitripterus americanus, the sea raven, is a species of marine ray-finned fish belonging to the subfamily Hemitripterinae of the family Agonidae. The sea raven is found along the Atlantic coast of North America.

Taxonomy

Hemitripterus americanus was first formally described as Scorpaena americana in 1789 by the German naturalist Johann Friedrich Gmelin with its type locality given as "America".[2] In 1801 Marcus Elieser Bloch and Johann Gottlob Theaenus Schneider described a new species Cottus tripterygius and in 1829 Georges Cuvier proposed the new monotypic genus Hemitripterus for C. tripterygius which was later shown to be a junior synonym of Gmelin's S. americana.[3][2] The genus Hemitripterus is classified within the subfamily Hemtripterinae of the family Agonidae.[4]

Description

Hemitripterus americanus are variable in color from blood red to reddish purple to yellow brown. The ventral surface is typically yellow. The have large heads and a robust, tapering body. There are obvious fleshy folds on the head and lower jaw. There is also an unusual ragged layer of skin on the first dorsal fin. They have large, fan-shaped pectoral fins and a small caudal fin. They have a broad moutrh which is lined with several rows of teeth.[5] The maximum published total length is 62 cm (24 in) and the maximum published weight is 3.2 kg (7.1 lb).[1]

Distribution and habitat

Hemitripterus americanus is found along the Atlantic Coast of North America, from Labrador in Canada to Chesapeake Bay.[1] They are demersal fish found over rocky or hard substrates but can be found anywhere in the water column.[5]

Biology

Hemitripterus americanus is considered to be a voracious predator which preys on a wide variety of animals including benthic invertebrates and fish such as herring, sand eels and silver hake. When they are removed from the water they inflate and if returned to it they cannot submerge. Spawning adults attach their eggs to the bases of sponges.[1]

Hemitripterus americanus ( French )

provided by wikipedia FR

L'hémitriptère atlantique (Hemitripterus americanus, (en):Atlantic sea raven) était classé dans la famille des cottes et des chaboisseaux, les Cottidae. Maintenant, la famille des Hemitripteridae a été créée pour l'inclure. Il partage d'ailleurs avec les chaboisseaux l'appellation de « crapaud de mer » et de « plogueuil » (Îles-de-la-Madeleine). Ses autres noms anglais : whip sculpin, gurnet, puff-belly, scratch-belly. Il se distingue des cottes et chaboisseaux par ses appendices charnus sur la tête, par l'apparence déchiquetée de la première nageoire dorsale et par sa denture plus développée. Sa peau est sans écaille et pourvue de piquants sur la ligne latérale et près des nageoires dorsales. Le dessus est d'une couleur brun rougeâtre, marbré de brun foncé et très versicolore, le ventre jaunâtre et les nageoires bigarrées de pâle et de foncé. Sa taille peut atteindre 60 cm et son poids de 3 kg, ce qui doit être de moins en moins fréquent aujourd'hui.

L'hémitriptère, vivant dans les fonds rocheux ou durs, a un menu qui correspond bien à sa puissante denture : vorace, il consomme tout invertébré disponible, petits crustacés, coquillage et oursins, tout comme il se nourrit de poissons, tel le hareng, le lançon ou le merlu argenté. Sa propre chair est peu consommée par les humains, cette dernière étant bien parasitée (par des nématodes) et le poisson présentant plusieurs épines. On s'en sert un peu comme boëtte pour la pêche du homard. Au sortir de l'eau (aussi lorsqu'il avale un grand volume d'eau de mer), le ventre de l'hémitriptère atlantique se gonfle de telle sorte qu'une fois remis à l'eau il est incapable de plonger.
