A notable example is Suruga Bay, the deepest bay in Japan, where the economically important Sakura shrimp (Lucensosergia lucens) fishery has substantially declined in recent decades; however, whether river discharge has contributed to this decline remains unclear. This study examines the effect of river discharge on the catch and biomass of Sakura shrimp in this bay. We integrated the statistical analyses of four decades of fishery data (1983-2020) with a three-dimensional ecosystem model (STOC-LT) configured for 2020 under altered river discharge scenarios from four major rivers. The ecosystem model successfully reproduced the observed seasonal patterns of Chl-a and water temperature in Suruga Bay, strengthening the basis for scenario analyses. The scenario analysis revealed fundamentally distinct seasonal pathways. In spring, the increased discharge enhanced the estimated catch through nutrient-driven spatial redistribution near the Fuji River plume, whereas the simulated biomass remained stable, indicating increased catchability rather than population growth. In autumn, both models converged on negative responses; a 20% increase in the river discharge reduced the simulated biomass from 5.22 × 10^-7 to 4.89 × 10^-7 mgC m^-3 and estimated catch from 43.5 to 33.1 ton/day, likely as the warmer river water constrains larval survival and reduces catchability. These findings demonstrate that the effects of river discharge on Sakura shrimp fisheries critically depend on the seasonal environmental context, highlighting the need for season-specific management of river discharge.</p>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"220 ","pages":"108242"},"PeriodicalIF":3.4,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148376236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed a technique based on multiplex PCR combined with the nucleic acid chromatographic strip (mPCR-NACS), which can simultaneously detect three representative harmful microalgae in the East China Sea, i.e., Heterosigma akashiwo, Prorocentrum donghaiense, and Karenia mikimotoi. Here, three pairs of specific primers (Ha-FP/Ha-RP, Pd-FP/Pd-RP, and Km-FP/Km-RP) containing specific tags, spacer, and primer sequences were designed based on the ribosomal large subunit rDNA D1-D2 of the target species. The mPCR amplification system was initially established using these specific primers, followed by the optimization of key parameters to increase efficiency, including hybridization temperature (40°C) and detection probe concentration (5.0 μM). Next, a cross-reactivity test with representative control algal species revealed the specificity of the developed mPCR-NACS. A further stability test showed that non-target microalgal species did not interfere with the detection of target microalgae by mPCR-NACS, demonstrating excellent anti-interference ability. In addition, a final evaluation with simulated natural water samples showed that the detection limit of mPCR-NACS could reach 10 cells mL^-1.

However, the lack of standardized practices has hindered cross-study comparisons and limited our ability to thoroughly assess the community structure, diversity and biogeography of N₂O-reducing microorganisms. To address these knowledge gaps, a bioinformatic workflow was developed to standardize the processing of nosZ gene datasets originating from high-throughput sequencing. We first manually curated and constructed a comprehensively annotated reference protein sequence database containing 3,361, 5,665, and 96 sequences from the NosZ-I, NosZ-II, and NosZ-III clades, respectively. Integrated with this database, we developed NosZRef, a fast, accurate and scalable analytical pipeline for nosZ gene profiling. With one single command, NosZRef provides users full-pipeline analysis from raw reads to statistical and visualization outputs. We employed NosZRef to profile nosZ genes across diverse depths in the Tara Oceans dataset, revealing that the three nosZ clades exhibit distinct depth-dependent distribution patterns and ecological strategies. In summary, NosZRef offers high specificity and comprehensive coverage for accurate profiling of N₂O-reducing microorganisms in oceanic ecosystems from high-throughput sequencing data, providing a useful tool for investigating microbially mediated N₂O reduction in oceanic environments.

Here, two years of continuous field observations (2023-2024) were conducted in the Neopyropia yezoensis aquaculture area of the Subei Shoal, China, to examine the seasonal succession of epiphytic green algal communities and their natural detachment during spring. Epiphytic communities exhibited a clear and repeatable successional pattern, shifting from dominance by cold-tolerant taxa in early spring to increased prevalence of Ulva prolifera by April, a transition closely associated with rising water temperatures. Natural detachment occurred continuously throughout the cultivation period, rather than being confined to the harvest stage. Detached biomass increased in concert with attached biomass, indicating a stable and persistent coupling between biomass accumulation and natural detachment in late spring. Spatial extrapolation suggested that natural detachment reached approximately 327.14 t and 656.96 t (wet weight) in April 2023 and 2024, respectively. Although these amounts are smaller than peak floating biomass during summer green tides, their seasonal timing coincides with the initial phase of bloom formation and may contribute to the background supply of floating algal material. Together, these findings provide field-based evidence that aquaculture-associated epiphytic algae represent a sustained early-season source of algal input to coastal waters.

The rewilding process began in 2004 after breaching an external tidal wall. We evaluated changes in vegetated and unvegetated areas using Landsat satellite imagery (1994–2024) and quantified C_org and N_T stocks and burial rates in wild and rewilded sediments, including vegetated saltmarsh (<em>Sarcocornia</em> sp.) and bare sediments colonized by microphytobenthos (MPB).

The physiological and behavioural responses of oysters suggest that they perform better under high temperatures (27 °C) as they maintain metabolic rate while increasing feeding. Oysters were also able to tolerate repeated periods of hypoxia (&lt;2 mg O₂ L⁻¹) during a heatwave by maintaining metabolic rate and reducing feeding costs. Conversely, soft-shell clams experienced stress under the induced heatwave and showed signs of metabolic depression. Repeated hypoxia during the heatwave resulted in elevated physiological responses in clams, suggesting elevated energy requirements under these stressors.
