“…Numbers beside symbols indicate species, as for Figure 2. (Shinohara et al, 1992) (catch-record depth: 50-1,497 m; Supplementary Table 1). Bothrocara tanakae and S. kaupii are bottom-dwelling fish species with 14 C Bulk values of ∼0 , suggesting that their diets are ultimately derived from both the Oyashio and Tsugaru/Kuroshio currents.…”

To study the influence of different ocean currents on the trophic spectra found in a sympatric fish community, we analyzed the radiocarbon contents (Δ14C) and stable carbon (δ13C) and nitrogen (δ15N) isotopic compositions in their bulk muscle tissues and the δ15N of individual amino acids in 26 species of demersal fish collected from off Tohoku (Pacific coast), northeastern Japan. The Δ14C values of the fish varied from –42 to +41‰, consistent with the Δ14C of the dissolved inorganic carbon in the cold Oyashio Current (typically about –50‰) and the warm Kuroshio Current (typically about +50‰). The trophic positions (TPs) of the fish estimated from the δ15N values of amino acids increased from 3.1 to 4.5 with increasing snout length. A negative correlation was observed between Δ14C and TP in gadiform fish and flatfish, suggesting that the Oyashio Current delivers a high TP diet to these fish groups. These results suggest that the trophic ecology of marine fish in the coastal western North Pacific is primarily controlled by the two major surface water currents, but is also significantly influenced by a combination of species-specific feeding and migration strategies.

“…However, the small specimens (< 50 mm SL: FAKU 200380-200384, 201398, 201435, 201437) and a large specimen (FAKU 200470, 144.0 mm SL) lacked prickle-like scales on the head, being rather similar to Malacocottus gibber Sakamoto, 1930. Notwithstanding this, the large specimen had six gill rakers, falling within the range of M. zonurus [4-9 in M. zonurus vs. 9-15 in M. gibber (see Shinohara et al 1992)].

An annotated checklist of benthic fishes on the western part of Kitami-Yamato Bank off northeastern Hokkaido, Japan in the southern Sea of Okhotsk, is presented based on voucher specimens with accompanying color photographs. All material was collected in late April, 2013 and 2014 by the bottom trawl net, a total of 450 specimens being classified into 92 species representing 21 families. These include Bathyraja trachouros, the first record from the Sea of Okhotsk, and Careproctus segaliensis, only the second confirmed record of the species.

Salinisphaera japonica sp. nov., a moderately halophilic bacterium isolated from the surface of a deep-sea fish, Malacocottus gibber, and emended description of the genus Salinisphaera A moderately halophilic, slightly acidophilic, aerobic bacterium, designated strain YTM-1 T , was isolated from the body surface of Malacocottus gibber. Cells were Gram-stain-negative, short rods or cocci, approximately 0.9-1.1 mm long and 1.0-1.8 mm wide. Strain YTM-1 T was able to grow with 1-30 % NaCl (optimum, 7.5-10 %, w/v), at 4-30 6C (optimum, 20-25 6C) and at pH 3.8-9.5 (optimum, pH 5.0-5.5). Phylogenetic analysis based on 16S rRNA gene sequence similarities showed that strain YTM-1 T belonged to the genus Salinisphaera with low similarity values to the type strains of recognized species of this genus (,94.8-94.4 %). The polar lipids of strain YTM-1 T consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylserine, three unknown phospholipids and one unknown lipid. The predominant isoprenoid quinone was Q-8. The major fatty acids were C 19 : 0 v8c cyclo, C 18 : 1 v7c, C 16 : 1 v5c and C 16 : 0 . The DNA G+C content of strain YTM-1 T was 67.3 mol%.These phylogenetic, physiological and chemotaxonomic data indicated that strain YTM-1 T represents a novel species of the genus Salinisphaera, for which the name Salinisphaera japonica sp. nov. is proposed. The type strain is YTM-1 T (5JCM 18087 T 5CECT 8012 T). An emended description of the genus Salinisphaera is also proposed.The genus Salinisphaera in the class Gammaproteobacteria was proposed by Antunes et al. (2003). At the time of writing, five species belonging to the genus Salinisphaera have been described: Salinisphaera shabanensis E1L3A T from brine of a salt well in Yunnan, China (Zhang et al., 2012).This study describes a slightly acidophilic, moderately halophilic bacterium, strain YTM-1 T , which was isolated from the body surface of a deep-sea fish, Malacocottus gibber (Fig. S1, available in IJSEM Online) captured at Nyuzen, Toyama Bay, Japan, at a depth of 400-800 m, in February 2009 (Tsuruwaka andShimada, 2011). Malacocottus gibber is a member of the family Psychrolutidae (superfamily Cottoidea) that is endemic to the Japan Sea (Shinohara et al., 1992;Nelson, 2006). In a previous study, we successfully reared and spawned Malacocottus gibber in our laboratory (Tsuruwaka and Shimada, 2011).Abbreviations: ML, maximum-likelihood; NJ, neighbour-joining.
