    <p>The Tsushima Strait and the neighboring waters has been known as major spawning and nursery grounds for migratory fishes due to the high standing stocks of the plankton community in spring to summer. In the present study, spatial and temporal variations in taxonomic composition, standing stocks and productivity of the mesozooplankton community were investigated in the southwestern Japan Sea to explore their variations during the productive seasons. Both spatial and temporal fluctuations were significant for mesozooplankton standing stocks while only temporal variability affected their productivity. The mesozooplankton community was split into one coastal group, represented by cladocerans and noctilucids throughout the seasons, and five pelagic groups, predominated by calanoids, cyclopoids and copepod nauplii, with temporal replacement during spring to summer. The coastal community group contained the additional standing stocks of cladocerans and noctilucids along with the predominant copepods from the other groups and thus resulted in the spatial difference in mesozooplankton standing stocks between coastal and pelagic sites. Three pelagic community groups were characterized by the abundant appearance of noctilucids and clustered toward the pelagic stations neighboring the coastal community group. Generalized linear models demonstrated that salinity was a significant explanatory variable for standing stocks of mesozooplankton and coastal taxonomic groups (i.e., cladocerans and noctilucids). These findings suggest that the spatial and temporal variations in mesozooplankton standing stocks are a mixture of the pelagic community groups with the coastal community group advected toward the pelagic sites.</p>

    <p>Juvenile yellowtail <i>Seriola quinqueradiata</i> follow floating algae in the East China Sea and have been caught for natural nursery stocks of mariculture in Japan. However, we have still limited knowledge of prey sources supporting their early growth. Here, we clarify prey organisms and sources of the juvenile fishes that appeared in the Satsunan area, southern Japan based on stable isotope ratios and metabarcoding analysis. Stable isotope ratios of carbon and nitrogen for yellowtail juveniles were equivalent to those for zooplankton and fish larvae that appeared in the Kuroshio and its neighboring waters. The most predominant and frequently appearing prey revealed by metabarcoding analysis was calanoid copepods. The next in importance was poecilostomatoid copepods for smaller juveniles and appendicularians and chaetognaths for larger juveniles. A positive correlation was found for the juvenile growth index to the contribution of calanoid copepods of their gut-content DNA. These results suggest that juvenile growth of yellowtail that appeared in the Satsunan area is supported by not benthic animals on floating seaweeds but by zooplankton in the water column.</p>

    Organic mercury, inorganic mercury and total mercury concentrations in phytoplankton (<0.1 mm) and zooplankton (>0.1 mm) collected in Kagoshima Bay, Japan were measured from 2017 to 2019 to estimate the impact of mercury discharged from submarine volcanoes on ecosystems; submarine volcanic activity continues at a depth of 200 m in the inner part of Kagoshima Bay. The total mercury concentrations in phyto- and zooplankton collected by vertical hauling at 0–200 m at just above the submarine volcano were in the range of 0.11–2.0 mg kg−1 (avg. 0.67 mg kg−1) and 0.090–0.56 mg kg−1 (avg. 0.21 mg kg−1), respectively. These values were one order of magnitude higher than the values in plankton collected in the central part of Kagoshima Bay. Organic mercury concentrations in phyto- and zooplankton were <0.010–0.071 mg kg−1 (avg. 0.028 mg kg−1) and 0.012–0.25 mg kg−1 (avg. 0.10 mg kg−1), respectively, for the inner part, and <0.010–0.040 mg kg−1 (avg. 0.010 mg kg−1) and <0.010–0.025 mg kg−1 (avg. 0.012 mg kg−1), respectively, for the central part. The values obtained in the inner part of the bay increased in summer and decreased in winter, which was consistent with changes in seawater mercury concentrations affected by volcanic activity. The organic mercury concentration in zooplankton collected just above the submarine volcano showed a size dependency, and a higher value was observed in the larger size, which suggested that the discharged mercury from the volcano was absorbed and concentrated through the ecosystem.

    <p>The northern Satsunan area, comprising the mouth of Kagoshima Bay and Osumi Strait, is an important spawning and nursery ground for Japanese jack mackerel <i>Trachurus japonicus</i> in Japan. Upwellings frequently occur at the mouth of the bay during winter and spring, and the consequent nutrient supply promotes phytoplankton blooms. This study examined how <i>T. japonicus</i> utilizes upwelling (Kagoshima Bay) and non-upwelling areas (Osumi Strait) as larval nursery grounds. Densities and growth rates (measured as the average width of the last three otolith increments) of <i>T. japonicus</i> larvae in both areas were compared to determine the upwelling influence on nursery ground formation. The mouth of the bay had lower temperature and salinity but higher chlorophyll-<i>a</i> concentrations and prey density than that of the strait. Densities of larvae were consistently higher in the bay than in the strait, indicating that the main nursery of <i>T. japonicus</i> is formed in Kagoshima Bay. No significant differences were observed in the growth rates of larvae among areas, suggesting that lower temperatures and prey availability are growth limiting factors in the mouth of the bay and the strait, respectively, and the Osumi Strait could also provide a favorable nursery area.</p>

    <p>While it has been suggested that advections of coastal waters stimulate plankton standing stocks and productivity in the oligotrophic Kuroshio, there is still limited information. Here, we explore the source and process of coastal waters advected to the Kuroshio using particle-tracking experiments with a high-resolution coastal ocean model. Advections of coastal waters to the Kuroshio were stimulated by encountering frequent disturbances such as meandering and eddy near the Kuroshio front. The source of coastal waters advected to the Kuroshio were the largest from southern Kyushu throughout the year and from the East China Sea during winter to spring. Zooplankton biomass fluxes across the Kuroshio front were equivalent to 2 to 44% of those across the Kuroshio path. The estimated fluxes across the Kuroshio front were comparable to zooplankton biomass increase by their growth rates reported in the Kuroshio. These results suggest that the coastal zooplankton community advected to the Kuroshio supports food requirements for the fish community in the Kuroshio.</p>

    <p>It has been thought that food availability for fish larvae was poor in the Kuroshio because of the low standing stocks of plankton in the oligotrophic conditions under thermal stratification throughout the year. Despite a potential risk or disadvantage for larval survival and growth, Kuroshio and its neighbouring waters are nursery grounds for the early life stages of various fishes. Here, we compared the growth activity of fish larvae among 15 taxonomic groups, including 11 families in the Kuroshio and its neighbouring waters, based on protein synthetase activity and protein contents. Protein-specific (<sub>sp</sub>AARS), individual-based aminoacyl tRNA synthetase activities (<sub>i</sub>AARS), and protein contents (PRO) of fish larvae ranged from 2 to 232 nmol PPi mg protein<sup>−1</sup> h<sup>−1</sup>, from 1 to 21 μmol PPi ind<sup>−1</sup> d<sup>−1</sup>, and from <1 to 26 mg ind<sup>−1</sup>, respectively. <sub>sp</sub>AARS, <sub>i</sub>AARS and PRO were variable among the taxonomic groups and were not classified between mesopelagic groups and the others. Compiling these measurements among all taxonomic groups, a significant negative correlation was found for <sub>sp</sub>AARS to PRO. The correlation showed no significant difference between the Kuroshio and its neighbouring coastal waters, indicating that growth activities to fish larvae body mass were comparable in the Kuroshio and its neighbouring waters. Based on nonmetric multidimensional scaling on <sub>sp</sub>AARS, <sub>i</sub>AARS and PRO among 15 taxonomic groups, two different groups were classified for fish larvae, represented by the high <sub>i</sub>AARS under the high PRO but low <sub>sp</sub>AARS (Group 1) and the low <sub>i</sub>AARS under the low PRO but high <sub>sp</sub>AARS (Group 2), representing the different life strategies for larval growth among the taxonomic groups. The present findings suggest that these biochemical indices are useful for evaluating the growth activity of fish larvae among various taxonomic groups and that food availability is not poor enough to support larval growth in the Kuroshio and its neighbouring waters.</p>

    <p>The prey of whale sharks (<i>Rhincodon typus</i>) visiting the northern Satsunan area (western North Pacific Ocean) was investigated using microscopic and metabarcoding analysis of their faecal pellets. The stable isotope ratios of the dorsal fin and faecal pellets from the whale sharks were compared with those of their potential prey (plankton and fish larvae). Microscopic analysis identified protozoans (foraminifera) and metazoans (copepods, ostracods, and amphipods) but unclassified material was predominant in their faecal pellets. Metabarcoding analysis detected metazoans in the faecal pellets, represented by copepods, ostracods, amphipods, hydrozoans, and tunicates. Comparison of stable isotope ratios (δ<sup>13</sup>C and δ<sup>15</sup>N) from their dorsal fin and faecal pellets with those of zooplankton in the northern Satsunan area showed different feeding histories for the whale sharks appearing in the northern Satsunan area.</p>

    Trophic sources and pathways supporting early life stages are crucial for survival of forage fishes recruiting around the oligotrophic and unproductive Kuroshio. However, information is limited for the Kuroshio planktonic food web and its trophodynamics because of its high biodiversity. Here, we explore trophic sources and linkages in the Kuroshio plankton community using metabarcoding analysis of gut-content DNA for 22 mesozooplankton groups. The major prey was dinoflagellates and calanoids for omnivorous groups, and calanoids and gelatinous organisms for carnivorous groups. Larvaceans and hydrozoans were the most frequently appeared prey for both omnivores and carnivores, whereas they were minor constituents of the available prey in water samples. Although calanoids overlapped as major prey items for both omnivores and carnivores because they were the most available, contributions from phytoplankton and gelatinous prey differed among taxonomic groups. Further analysis of the metabarcoding data showed that in addition to omnivorous copepods like calanoids, gelatinous groups like larvaceans and hydrozoans were important hubs in the planktonic food web with their multiple trophic linkages to many components. These findings suggest that gelatinous organisms are important as supplementary prey and provide evidence of niche segregation on trophic sources among mesozooplankton groups in the Kuroshio.

    To evaluate the importance of the northern Satsunan area in southern Japan as a spawning and nursery ground for chub mackerel (<italic>Scomber japonicus</italic>), we investigated the early life history characteristics (e.g., larval distribution, feeding habits, and growth) of <italic>S. japonicus</italic> over five successive years. This area is considered the main habitat and spawning ground of the congeneric species, <italic>S. australasicus</italic>. Using polymerase chain reaction-restriction fragment length polymorphism analysis, we first confirmed that <italic>S. japonicus</italic> larvae were abundant in the northern Satsunan area, potentially representing a major spawning and nursery ground in the Japanese Pacific coastal area. The number of recorded larvae started to increase in 2016, corresponding to the population dynamics of the Pacific stock of the species, which has shown increasing trends in recent years. Morphological and DNA metabarcoding analyses of gut contents and stable isotope analysis showed that, in addition to copepods, the larvae fed substantially on appendicularians. The trophic pathway involving appendicularians might support the feeding habits of <italic>S. japonicus</italic>, promoting its coexistence with other dominant species. Both the instantaneous growth rate and daily specific growth rate were comparable to those in the southern East China Sea, which is the main spawning and nursery ground of the species. Our data strongly suggest that the northern Satsunan area has favorable conditions for sustaining high larval population densities, even during phases with high population numbers. Our results provide insights for the fisheries management for <italic>S. japonicus</italic> in the Japanese Pacific coastal area, especially during high-stock periods.

    Vertical nitrate fluxes associated with turbulent mixing and upwelling around a small reef in the Kuroshio are quantified by continuously deploying a turbulence microstructure profiler with an attached submersible ultraviolet nitrate analyzer while drifting from the upstream to the downstream of the reef. Flow separations and trains of Kelvin-Helmholtz billows (thickness = 60 m) are identified using a shipboard ADCP and an echo-sounder. The turbulence diffusivity associated with the vigorous turbulent mixing reaches up to O(10−1 m2 s−1), resulting in strong nitrate fluxes of O(1–103 mmol m−2 day−1). In addition, large differences between the upstream and downstream density profiles suggest a strong upwelling velocity of O(10−3 m s−1), as well as an upwelling nitrate flux of O(102 mmol m−2 day−1) in the entire subsurface layer.

    The euryhaline copepod <italic>Pseudodiaptomus inopinus</italic> play important roles in coastal waters as vectors of docosahexanoic (DHA) and eicosapentaenoic (EPA) acids for larval fish. While DHA and EPA in polar lipids (PLs) are more effective for fish larval development than non-polar lipid forms (NLs), there is little knowledge how much these lipids are accumulated in copepods from microalgae and are effective for early development of fish larvae. We report PLs fatty acid profiles of <italic>P. inopinus</italic> fed DHA-poor microalgae and evaluate its significance as a food source for larvae development of <italic>Pagrus major</italic>, compared with DHA-enriched rotifers. Copepods and rotifers were fed a mixed diet of three algal species (<italic>Phaeodactylum tricornutum</italic>, <italic>Tisochrysis lutea</italic>, and <italic>Pavlova lutheri</italic>), in addition of DHA-supplemented Super Fresh Chlorella (SFC) for rotifers. Compared with SFC, the algal mixture had higher EPA but lower DHA. Copepods had higher DHA and EPA in total lipids than rotifers fed each diet. Copepod PLs were specifically enriched with DHA and their contents were higher than both rotifers. On the other hand, PLs EPA contents were comparable between preys, indicating that copepods selectively fortified the PLs. Fish culture experiment showed that larvae fed copepods had higher growth than those fed SFC-enriched rotifers. Principal component analysis for each organism fatty acid composition emphasized trophic modification of DHA by copepods toward larval fish. This study highlighted that <italic>P. inopinus</italic> contribute to enhanced growth of coastal larval fish by efficiently transferring DHA via copepod fatty acid metabolism.

    We examined the feeding habits of the dominant mesopelagic fish Sigmops gracilis larvae across the Kuroshio Current, southern Japan. The feeding incidence tended to decrease toward the offshore area. Copepods, amphipods, ostracods, and appendicularians were microscopically observed in the guts. Larvae fed substantially on copepods such as calanoids and appendicularians. Appendicularians were more frequently ingested toward the offshore area and were the most preferential prey item in all areas. The microbial production integrated by appendicularians would support mesopelagic fish larvae in addition to the ordinary trophic pathway through copepods.

    © 2020 John Wiley & Sons Ltd Many migratory fishes reproduce and recruit around the Kuroshio, and their survival of early life stages is supported by mesozooplankton. Mesozooplankton standing stocks and productivity equivalent to those on the continental shelf have been found in the Kuroshio; however, there is limited information on trophic sources and linkages to support the mesozooplankton community. Here, we evaluate mesozooplankton feeding on protists and their trophodynamics importance by removal bottle experiments in the Kuroshio of the East China (ECS-Kuroshio). Pico- and nano-autotrophs dominated chlorophyll a concentrations throughout the study sites across the continental shelf, within the Kuroshio path and in adjacent waters. Calanoid and poecilostomatoid copepods comprised more than 85% of mesozooplankton biomass. Significant mesozooplankton ingestion rates were found for nano-autotrophs based on size-fractionated chlorophyll; for haptophytes, chrysophytes, chlorophytes, and diatoms from pigment-based phytoplankton analysis; and for naked ciliates in the microzooplankton. Based on the estimates of individual carbon budgets, nano-autotrophs and naked ciliates ingested by mesozooplankton composed 39% of their food requirements, suggesting other available prey like nano-heterotrophs. These results imply that mesozooplankton ingestion in the ECS-Kuroshio has great impacts on protozoan and phytoplankton communities and their major trophic pathways are from nano-sized auto- and heterotrophs and ciliates to copepods.

    <p>The diet of the critically endangered Ryukyu-ayu <i>Plecoglossus altivelis ryukyuensis</i> in the middle reaches of the Kawauchi, Sumiyo, and Yakugachi Rivers, Amami-oshima Island, southern Japan was examined by gut content analysis and inferred from stable isotope signatures. No clear differences in diet composition were apparent among the rivers. Microalgae, such as diatoms and cyanobacteria, generally considered as important food, were only rarely observed in gut contents, whereas detritus was almost exclusively found. However, stable isotope signatures indicated that detritus was not directly utilized as a nutritional source, indicating that food availability was an issue for <i>P. a.ryukyuensis</i>.</p>

    <p>Temporal and spatial variations in the taxonomic composition, standing stocks (abundance and biomass), and protein synthetases activity of the mesozooplankton community in the northern Satsunan area were investigated. Although both variations in sources were significant for their standing stocks, temporal variability was predominant for their protein synthetases activity. A multivariate analysis on their taxonomic compositions identified six groups with large seasonality at the mouth of the Kagoshima Bay and two groups with less temporal variability. These were characterized by calanoids and poecilostomatoids. The mesozooplankton community demonstrated a higher abundance and biomass inside as compared to the outside of the Kagoshima Bay. However, similar protein synthetases activity was seen for both locations. Mesozooplankton protein synthetases activity was high, even when there was a low chlorophyll <i>a</i> average in the sampling layer owing to the increased presence of smaller mesozooplankton. In the sampling layer, individual body mass was lower and mesozooplankton abundance was higher at lower salinity averages. These results suggest that the temporal and spatial variations in the mesozooplankton standing stocks and protein synthetases activity are associated with the advections or extensions of small calanoids and poecilostomatoids with less saline waters.</p>

    © 2020 Elsevier Ltd Many foraging fishes spend their vulnerable life stages with low food availability in the oligotrophic Kuroshio. Although they are likely dependent on microbial production as their energy source, there is limited knowledge of the trophodynamics of the planktonic food web in the Kuroshio of the East China Sea (ECS-Kuroshio). Here, we demonstrate energy sources and feeding impacts of microzooplankton on the phytoplankton community based on size-fractionated dilution experiments in the ECS-Kuroshio. Naked ciliates were the most predominant among micro-sized heterotrophs biomass throughout the study area. Pico- to nano-phytoplankton such as Prochlorococcus and haptophytes contributed to total chlorophyll a concentrations. The apparent growth rates in non-diluted bottles without nutrient enrichment were significantly negative for Prochlorococcus and haptophytes. Microzooplankton grazing rates were higher for nano-phytoplankton (0.17–1.45 d−1) compared with those for pico- (0.18–1.23 d−1) and micro-phytoplankton (0.06–0.92 d−1). The community grazing impacts accounted for up to 122% of primary production. These results suggest that one major pathway at lower trophic levels in the ECS-Kuroshio is from pico- and nano-phytoplankton to microzooplankton. This pathway could support energy transfer to higher trophic levels through food resources of mesozooplankton and fish larvae.

    Plankton community structure, standing stocks and productivity were compared between upstream and downstream of the
    Tokara Strait based on Lagrangian oceanographic observations and sampling along the Kuroshio. Surface waters above 200m
    were represented by lower temperature and salinity, and nutrients and chlorophyll a concentrations at the subsurface were higher
    downstream than upstream. No significant difference was found in the zooplankton community structure, and the predominant
    components were naked ciliates for microzooplankton and copepods for net zooplankton. Although the protein synthetase activity
    of the net zooplankton community was high throughout the stations, large metazoans were one cause of the increased biomass and
    production rates downstream. These results suggest that the nutrient supply and phytoplankton increased at the subsurface, and
    the net zooplankton biomass and productivity increased downstream of the Tokara Strait.

    [Abstract] / Vertical nitrate fluxes associated with turbulent mixing and upwelling around a small reef in the Kuroshio are quantified by continuously deploying a turbulence microstructure profiler with an attached submersible ultraviolet nitrate analyzer while drifting from the upstream to the downstream of the reef. Flow separations and trains of Kelvin-Helmholtz billows (thickness = 60 m) are identified using a shipboard ADCP and an echo-sounder. The turbulence diffusivity associated with the vigorous turbulent mixing reaches up to O(10^−1 m^2 s^−1), resulting in strong nitrate fluxes of O(1–10^3 mmol m^−2 day^−1). In addition, large differences between the upstream and downstream density profiles suggest a strong upwelling velocity of O(10^−3 m s^−1), as well as an upwelling nitrate flux of O(10^2 mmol m^−2 day^−1) in the entire subsurface layer. /   / [Plain Language Summary] / Vertical nitrate fluxes associated with flow-topography interactions around a small reef in the Kuroshio Current are quantified using state-of-the-art oceanographic instruments. When the flow passes over a shallow sill on the flank of the reef, the velocity differences between layers intensify, resulting in a substantial vertical overturning and mixing of the water column. This turbulent mixing causes the observed nitrate flux from deep water to reach a value among the highest observed worldwide. /   / [Key Points] / • Flow separations and trains of Kelvin-Helmholtz billows mix the water column around a small reef in the Kuroshio / • Doming of isopycnals/nitraclines suggests strong upwelling in the lee of the reef / • Turbulent nitrate fluxes reach up to O(10^3 mmol m^−2 day^−1)

    We examined the feeding habits of Benthosema pterotum in Kagoshima Bay. Benthosema pterotum undertook diel vertical migration and preyed in shallow waters at night. The most frequently consumed prey were copepods, and B. pterotum selectively foraged on poecilostomatoids. Poecilostomatoids were more predominant in the Kagoshima Bay zooplankton community than in neighboring sites, which suggested that the B. pterotum preference for poecilostomatoids may be an adaptation by the local population to prey availability. Benthosema pterotum probably plays an important role as a biological pump contributor and as a mediator that links secondary production and higher trophic levels.

    <p> The aim of this study was to confirm the effect of magnesia mortar and <i>Shochu</i> distillation lees on the growth of microalgae in the sea. Cylindrical blocks made of four different materials, namely cement mortar (<i>C<sub>M</sub></i>), magnesia mortar (<i>M<sub>M</sub></i>), and cement and magnesium mortars containing <i>Shochu</i> distillation lees fermented by lactic acid bacteria (<i>C<sub>S</sub></i>, <i>M<sub>S</sub></i>) were used for experiments conducted in summer and winter. The blocks were placed in the sea covered with a net to prevent fish from eating the microalgae growing on them. Seawater temperatures were recorded with a temperature meter at 10-min intervals. Ten blocks were collected after three days, one–six weeks in the summer experiment, after one–three weeks in the winter experiment, and placed in an N, N-dimethylformamide solution. The concentrations of chlorophyll a were measured to determine the density of chlorophyll a in the microalgae on the blocks.</p><p> The seawater temperature was 26–31°C in the summer experiment and 17–21°C in the winter experiment. The density of chlorophyll a increased for one to two weeks after setting in the sea during the summer experiment and decreased gradually from three until six weeks after setting. The density of chlorophyll a in <i>M<sub>S</sub></i> was significantly higher than in <i>C<sub>M</sub></i> at one, three, and six weeks after setting in the summer experiment and one and two weeks after setting in the winter experiment. Magnesia mortar and <i>Shochu</i> distillation lees contributed to the growth of microalgae in the sea.</p>

    冬季から春季に北部薩南海域で2015年以降継続実施している小型浮魚類の仔魚を対象とした調査から、2016年まではマアジが優占していたのに対して、2017年以降、サバ属が圧倒的に優占していることが分かった。マアジ、サバ属ともに、湧昇現象のみられる鹿児島湾の湾口部で特に出現数は多かった。これまで本海域は ゴマサバの主要な産卵場であることが知られていたが、制限酵素断片長多型法により仔魚を種査定した結果、マサバ仔魚が圧倒的に優占して出現していることが分かった。今回得られた成果は、本海域において魚種交替、すなわち近年みとめられているマサバの資源量増加の兆候をとらえたものと考えられる。これまで北部薩南海域は資源高水準期にマイワシの主産卵場となることが知られていたが、マサバでも同様の現象がみられることが明らかとなった。
    冬季に本海域において優占して出現する魚類7種(マアジ、マサバ、カタクチイワシ、カサゴ属の複数種、ホウボウ科の複数種、ヨコエソ、アラハダカ)の仔魚を対象とし、消化管内容物の検鏡、DNAメタバーコーディング解析、炭素・窒素安定同位体比分析の3手法を用いて食性解析を実施した。その結果、マアジ、カタクチイワシ、ホウボウ科の複数種ではカイアシ類、マサバ、カサゴ属の複数種、中深層性種であるヨコエソとアラハダカではカイアシ類に加え、高い割合で尾虫類を摂餌していることが明らかとなった。本海域の低次食物網において、尾虫類を介した微生物食物網が重要な役割を果たしており、種間で餌生物に対する競合を緩和し、多くの種の共存を可能にしている可能性が示唆された。
    マアジとマサバの成長解析を行い、鹿児島湾口部と湾外とで比較した結果、成長に違いはみられなかった。2種の仔魚にとって、湾口部から湾外にかけての広範囲の海域が好適な成育場としての機能を果たしていると考えられた。

    本研究の目的は、実用的な動物プランクトン生産力測定法を確立し、日本周辺海域の動物プランクトン生産力マップを作成して、海盆~グローバルスケールの動物プランクトン生産力を測定するための研究基盤を形成することにある。本研究の目的を達成するため、①既往法のレビューと評価、②実用的なガイドライン確立、③方法論の比較と妥当性検証、④既往データベースを使った生産力測定、⑤動物プランクトン生産力のホットスポット探索、という課題rを設けた。今年度は、以下のような成果を得た。
    課題①については、伝統的測定法を総括し実用化に向けた前提条件・利点・問題点を記述したレビュー論文を作成し、Progress in Oceanographyに投稿した。課題②については、伝統的測定法のうち経験的モデル(Empirical Models)・卵生産法(Egg Production Method)のガイドラインを作成し、国際科学組織(PICES)のHPに掲載する予定である。課題③については、生化学的手法(Chitobiase Method・AARS Method)と伝統的測定法(Natural Cohort Method)による動物プランクトン生産力の比較結果を国際作業部会の報告書として作成中である。課題④および⑤については、既往データベースに経験的モデルを展開したところ、親潮域よりも黒潮域の動物プランクトン生産力が高いことが分かった。
    来年度は、課題③~⑤に必要な情報を補充・強化すると共に、研究成果を学術論文・報告書などで公表できるように努める。

    We analyzed carbon and nitrogen stable isotope ratios of zooplankton from the sub-arctic to tropical western North Pacific and the Chukchi Sea. Our results clearly showed that a similar regularity between the food chain and the N / C isotope ratio, regardless structure of the food web and biological species. Isotopic analysis of meso-zooplankton community in the Kuroshio current region suggested that the offshore area use energy sources derived from regenerative nutrient and nitrogen fixation. In addition, the isotopic ratios of the community of diatoms, cyanobacteria and juvenile fish, large phytoplankton is minor as a trophic source of meso-zooplankton community in the Kuroshio and major prey items of fish larvae are small copepods.
