Sebastes schlegelii és una espècie de peix pertanyent a la família dels sebàstids i a l'ordre dels escorpeniformes.[4]
Fa 65 cm de llargària màxima[5] i 3,1 kg de pes.[6] 13 espines i 11-13 radis tous a l'única aleta dorsal i 3 espines i 6-8 radis tous a l'anal. Aletes pectorals amb 17-18 radis tous i pelvianes amb 1 espina i 5 radis tous. Absència d'aleta adiposa. Línia lateral contínua.[7][8][9] És de color gris amb taques fosques i presenta franges fosques a les galtes.[10]
És ovovivípar,[11][12] pon entre 44.000 i 780.000 ous[13] i, al Territori de Primórie (Rússia), el període reproductiu té lloc entre els mesos de maig i juny.[14]
El seu nivell tròfic és de 3,1.[15]
Pot ésser infestat per Microcotyle sebastis.[16][17]
És un peix marí, demersal[18] (entre 3 i 100 m de fondària) i de clima temperat, el qual viu al Pacífic[19] nord-occidental: les àrees properes a la costa i de fons rocallós[20] (encara que els juvenils es troben associats amb algues a la deriva)[21][22] de tot el Japó[23][24][25][26][27] (llevat de les illes Ryukyu),[28] la península de Corea[29][30][31][32][33] i el nord-est de la Xina,[28][34] incloent-hi el mar de la Xina Oriental,[35][36][37] la mar del Japó[19][38][39][40] i la mar Groga.[35][39][36][41][42][3][9][43] Segons sembla, n'hi ha establerta una població des de l'any 2008 al sud-oest dels Països Baixos (a l'Escalda Oriental),[44] una zona les condicions de la qual li són favorables, ja que són comparables a les de la seua àrea de distribució original. Aquesta introducció és probable que hagi estat deguda com a conseqüència del comerç de peixos d'aquari i la seua posterior posada en llibertat o al seu transport accidental en els tancs d'aigua de llast d'algun vaixell.[28][45]
És inofensiu per als humans,[9] el seu índex de vulnerabilitat és d'alt a molt alt (68 de 100),[46] té una longevitat de 20 anys,[5] és criat comercialment al Japó[9] i Corea del Sud,[28] i accepta fàcilment viure en un aquari.[47] A causa del seu alt valor comercial, aquesta espècie ha estat un dels principals objectius de la piscicultura durant els darrers 10 anys i, per exemple, la seua producció comercial a Corea del Sud és la segona en importància després de la de Paralichthys olivaceus.[48]
Sebastes schlegelii és una espècie de peix pertanyent a la família dels sebàstids i a l'ordre dels escorpeniformes.
Sebastes schlegelii, also known as the Korean rockfish, Northern black seaperch, and Black rockfish, is a predatory species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae It is found in the Northwest Pacific Ocean.
Sebastes schlegeli was first formally described in 1880 by the German zoologist and paleontologist Franz Martin Hilgendorf with the type locality given as Tokyo and Hakodate in Japan.[2] Some authorities place this species in the subgenus Acutomentum, of which it is the type species.[3] The specific name honours the German ornithologist and herpetologist Hermann Schlegel, who, cowrote Fauna Japonica with Coenraad Jacob Temminck in which they reported this species as S. inermis.[4]
The species is found in the Northwest Pacific Ocean,[5] off China, the Korean Peninsula and Japan.[1]
S. schlegelii are blackish with black pelvic, anal and caudal fins. The seaperch has a total of 8 weak head spines. It is black when young and turns a mottled gray on the sides with age, often nearing white. This species can vary greatly in size between bodies of water. They can live for up to 18 years, and older individuals are often much larger than average; the maximum recorded length is 60 cm (24 in). The record is 6.6 lb (3 kg).[1]
S. schlegelii is ovoviviparous and breed via internal fertilization,[1] females storing sperm until the development of the eggs. The phases between the start of the process and the end are separated by several months. The majority of the young are reared in late winter to early spring. Females produce between 125,000 and 1,200,000 eggs every breeding season. However it has been noted that not all of the eggs are released every year. It has been occasionally observed that the female may absorb the eggs back into her system.
Along with other close related Sebastes species in the Northwest Pacific Ocean, a duplicated copy of the amh gene (called amhy) is the master sex-determining gene for S. schlegelii.[5] In vitro experiments demonstrate that the overexpression of amhy causes female-to-male sex reversal in S. schlegelii.[5]
It is a pelagic fish, occurring on the continental shelf. Like other pelagic fish, they spend most of their time amid the water columns and are generally associated with rougher terrain.[1] Juveniles are often associated with rafts of seaweed.[1]
Lepeophtheirus elegans is a species of sea lice reported on S. schlegelii.[6]
They make up an important component of nearshore fisheries in northern Asia. The preference of the species for rough terrain can make it somewhat inconvenient for commercial fisheries, which are often situated in nearshore, shallow water, and rocky areas (reefs). The species is a popular quarry for recreational anglers.
