    Description: We propose a new equation to describe the relation betweenotolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish. The equation was developed by applying a mathematical smoothing method based on an allometric equation with a constant term for walleye pollock (Theragra chalcogramma) —a species that shows an extended longevity (〉20 years). The most appropriate equation for defining the relation between OL and FL was a four-phase allometric smoothing functionwith three inflection points. The inflection points correspond to the timing of settlement of walleye pollock,changes in sexual maturity, and direction of otolith growth. Allometric smoothing functions describing therelation between short otolith radius and FL, long otolith radius and FL, and FL and body weight were also developed. The proposed allometric smoothing functions cover the entirelifespan of walleye pollock. We term these equations “allometric smoothing functions for otolith and somatic growth over the lifespan of walleye pollock.”

    Hatching date, nursery grounds, and early growth of juvenile walleye pollock (Theragra chalcogramma) off northern Japan* (2021)

    Description: Walleye pollock (Theragra chalcogramma) is widely distributed in the North Pacific Ocean and plays an important role in coastal subarctic ecosystems. The Japanese Pacific population of this species is one of the most important demersal fishes for commercial fisheries in northern Japan. The population is distributed along the Pacific coast of Hokkaido and the Tohoku area (Fig. 1), which is the southern limit of distribution of the species in the western North Pacific. In Funka Bay, the main spawning ground for this population, pollock spawn from December to March (Kendall and Nakatani, 1992). Planktonic eggs and larvae are transported into the bay, where juveniles usually remain until late July when they reach 60−85 mm in total length (Hayashi et al., 1968; Nakatani and Maeda, 1987). These juvenile pollock then migrate from Funka Bay eastward to the Doto area off southeastern Hokkaido (Honda et al., 2004). Many studies on eggs, larvae, and juveniles of the species have been conducted in or near Funka Bay, but little information is available on the ecology of the early life stages in the Tohoku area. Hashimoto and Ishito (1991) suggested that eggs are transported from Funka Bay southward to the Tohoku area by the coastal branch of the Oyashio Current, but there has been no study to verify this hypothesis.

    Description: The distribution of Holocene benthic foraminifer species in bottom sediments in the Izu-Bonin Arc region of the northwestern Pacific Ocean has been investigated on the basis of 23 samples recovered from depths between 1100 and 4100 m. The benthic foraminifer faunas identified can be grouped into four species assemblages corresponding to four bathymetric zones: the abyssal zone (below 3700 m water depth), lower bathyal zone (2600-3600 m), lower middle bathyal zone (1600-2300 m), and upper middle bathyal zone (above 1300 m). The dominance of such an agglutinated foraminifer as Rhabdamminella sp. characterizes the abyssal zone, whereas assemblages devoid of calcareous foraminifers distinguish the zone deeper than the carbonate compensation depth (CCD). The occurrence of Bulimina aculeata d'Orbigny enables the recognition of the following three bathymetric zones: the lower bathyal zone characterized by such deep-sea species as Oculosiphon sp., Saccorhiza ramosa (Brady), Alabamina sp., and Pullenia bulloides (d'Orbigny); the lower middle bathyal zone defined by the occurrence of B. aculeata; and the upper middle bathyal zone characterized by the lack of B. aculeata as well as the dominance of such species as Uvigerina proboscidea Schwager and Sphaeroidina bulloides d'Orbigny. To estimate Quaternary and Pliocene paleobathymetry in the Izu-Bonin region, three water-depth indexes will work well: 3700 m for the CCD, 2300 m for the deepest habitat of B. aculeata, and 1600 m for the shallowest habitat of B. aculeata.
