First record of abnormal body coloration in a rockfish Sebastes trivittatus (Scorpaenoidei: Sebastidae)

Partial albinism in the Revillagigedo sea chub Kyphosus sectatrix (Perciformes: Kyphosidae) from Clarion Island, Mexico

“…2b). Abnormal color in this specimen coincides with description of teleost fishes with abnormal coloration (e.g., Kwun et al, 2016;Mansur, 2011;Muto et al, 2013Muto et al, , 2016 related to a dysfunctional melanin pigmentary system known as partial albinism. For the first time, we report this abnormal body coloration in K. sectatrix specimens in Mexican Pacific waters.…”

First report of abnormal body coloration in Sebastes koreanus (Actinopterygii: Perciformes: Sebastinae)

“…The abnormal body colorations of fishes are mainly due to the lack or excess of melanin, which causes albinism and melanism, respectively (Jawad et al 2013;Muto et al 2013). Such abnormal body color patterns of rockfish-es have also previously been reported in S. trivittatus (see Muto et al 2016). Overall, morphometrics were identical between the abnormal and normal specimens, and only the color form combinations were different.…”

“…Color variations have been reported in several fish species. They appear in both natural and aquaculture fishes (Muto et al 2016) but are frequently found in flatfishes reared in aquaculture environments (Venizelos and Benetti 1999;Macieira et al 2006;Burton 2010).…”

“…In the natural environment, several fish species, such as pricklebacks (Dictyosoma rubrimaculatum Yatsu, Yasuda et Taki, 1978), skates (Raja montagui Fowler, 1910;Raja brachyura Lafont, 1871;and Raja clavata Linnaeus, 1758), angel sharks (Squatina californica Ayres, 1859), and rockfishes {(Sebastes trivittatus Hilgendorf, 1880; Sebastes chrysomelas (Jordan et Gilbert, 1881); and Sebastes pachycephalus Temminck et Schlegel, 1843)} have also been reported to have sporadic albinism (Ball et al 2013;Lewand et al 2013;Muto et al 2013;Escobar-Sánchez et al 2014;Kwun et al 2016;Muto et al 2016) while Cephalopholis fulva (Linnaeus, 1758) and Lethrinus nebulosus (Forsskål, 1775) have shown melanisms of body coloration (Simon et al 2009;Jawad et al 2013). Albinism is a genetic abnormality that reduces melanin biosynthesis, resulting in partial or total lack of body color, typically producing a golden-orange color.…”

First record of leucism in the Blackbelly rosefish Helicolenus dactylopterus (Actinopterygii: Scorpaeniformes: Sebastidae), with notes on the lack of intragenic genetic divergence on the gene cytochrome c oxidase I (5’-COI) for the genus Helicolenus

“…In the Sebastidae family, only three cases of albinism and leucism were reported, namely leucism in Sebastes melanostomus (Eigenmann and Eigenmann, 1890) and albinism in Sebastes paucispinis Ayres, 1854 (Follett and Dempster 1966) and Sebastes pachycephalus Temminck and Schlegel, 1843 (Muto et al 2013) and no bibliographic reference was found for genus Helicolenus Goode and Bean, 1896. Although malpigmentations have been studied in aquaculture, there is little known from wild fish specimens (Muto, Takayama, and Kai 2016).…”
