“…Sculpin are one of the most abundant species in the East/Japan, Okhotsk, Chukchi, and Bering Seas; they are an important component of marine food webs as both prey and predator and feed on a variety of benthic invertebrates and other fish (Panchenko 2009;Gray et al 2017). Yang et al (2013) reported that in the coastal waters of Korea, the major prey for G. herzensteini as determined by stomach content analyses are fish, euphausiids, and shrimp. In addition, these authors found an ontogenetic dietary shift, such that smaller G. herzensteini (less than 15 cm) feed primarily on benthic invertebrates, including amphipods and polychaetes, and their main dietary change during growth is an increased contribution of other fish to their diets.…”

The aim of this study was to assess the temporal variability in the trophic structure of a fish community and the trophic levels of dominant fish species off the eastern coast of Korea. We analyzed the community composition and the stable carbon and nitrogen isotope ratios (δ 13 C and δ 15 N) for fish species in Hupo coastal waters over four seasons. Fish assemblages were mainly dominated by resident benthic and benthopelagic fish. In contrast, there were low numbers of pelagic fish, including migrating and occasional species, which varied significantly by season. The fish assemblages generally had relatively wide ranges of δ 13 C and δ 15 N (− 21.1 to − 16.3‰ and 10.0 to 14.2‰, respectively), reflecting a clear distinction between resident (mostly benthic or benthopelagic) vs migratory (mostly pelagic) fish. Resident species showed no seasonal differences in their isotopic signatures, whereas pelagic species showed temporal variability in δ 13 C and δ 15 N values. The isotopic niche of fish assemblages showed distinctly different patterns between spring-summer and winter-fall with the seasonal changes in the fish community. These patterns might be associated with seasonal variation in the fish community caused by seasonal changes in environmental conditions (e.g., hydrographic parameters and food availability). Our results can offer baseline information/trophic data for ecosystem models that can be used to evaluate the effects of climate on marine ecosystems.

“…The genus Gymnocanthus belongs to the family Cottidae (Nakabo 2013), contains nine species distributed in the northern coasts of the Pacific and the Atlantic Ocean including the adjacent Arctic (Froese and Pauly 2003;Nelson et al 2016;Fricke et al 2019). Among them, Gymnocanthus intermedius and Gymnocanthus herzensteini occurs in cold waters around Korea, Japan, and Russia of the western North Pacific, and are used as fishery resources (Kim et al 2005;Yang et al 2013).…”

Here, we report the complete mitochondrial genomes of the Sculpins species Gymnocanthus intermedius and Gymnocanthus herzensteini. The mitogenomes were determined to be 16,639 bp for G. intermedius and 16,691 bp for G. herzensteini. The mitogenomes comprised 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a non-coding region. We then used the mitogenome data to construct a phylogenetic tree for these two species and an additional three species within the order Scorpaeniformes.

Feeding and competitive relationships are considered qualitatively and quantitatively for 9 common species of sculpins (Cottidae) on the data of bottom-trawl surveys of the shelf and upper continental slope of Peter the Great Bay conducted in June-September of 2002-2009. Most of these species are facultative predators (elkhorn sculpin Alcichthys elongatus , blackedged sculpin Gymnocanthus herzensteini , plain sculpin Myoxocephalus jaok , snowy sculpin M. brandti , and great sculpin M. polyacanthocephalus ), two of them are euryphages (thorny sculpin Icelus cataphractus and graypurple sculpin G. detrisus ), and two other are benthophages (antlered sculpin Enophrys diceraus is benthophagous polyphage and thread sculpin G. pistilliger is benthofagous worm-feeder). Daily ration of these species is estimated as 2.4-3.6 % of body weight, with exception of antlered sculpin that is distinguished by lower feeding intensity (on average 1.0 % per day) due to features of its physiology. Food competition between sculpins is estimated as very low, at least in summer feeding season. Cases of significant overlapping of trophic niches noted for the predatory species, as common consumption of echiuran Echiurus echiurus and snow crab Chionoecetes opilio , are reasoned by high abundance and availability of these prey, not by real competition.
