The model, dealing with continuous shipper distribution, is discretized using the Finite Element Method to manage its complexity. To solve this intricate problem, a heuristic algorithm is developed.

Despite their ecological importance and high abundance, the feeding habits of these fishes have not yet been fully investigated in the Southwest Subtropical Atlantic. We examined spatial variations in the trophic ecology of two lanternfish (Myctophidae: Myctophiformes) species (<em>Gymnoscopelus bolini</em> and <em>Lepidophanes guentheri</em>). The analyses were based on two different regions of the southwest subtropical Atlantic influenced by distinct oceanographic regimes: (a) the north (20–28°S) and (b) south (28–34°S). Stomach content analysis (SCA) revealed that <em>G. bolini</em> preyed mainly on Euphausia spp. and Copepoda (%FO: 18.2), and <em>L. guentheri</em> preyed mainly on Euphausia spp. (%FO: 10.3) and Chaetognatha (%FO: 3.4). Stable isotope analysis (SIA) revealed that L. <em>guentheri</em> had different mean carbon (δ¹³C) and nitrogen (δ¹⁵N) values (± SD) between the north (δ¹³C: −19.9 ± 0.3 ‰; δ¹⁵N: 6.2 ± 0.9 ‰) and south (δ¹³C: −20.5 ± 0.7 ‰; δ¹⁵N: 8.5 ± 2.3 ‰) regions, while <em>G. bolini</em> (south only) had average values of δ¹³C: −20.4 ± 0.6 ‰, δ¹⁵N: 9.6 ± 2.1 ‰. In the southern region, there was similarity between the diets of <em>G. bolini</em> and L. <em>guentheri</em>, and the isotopic niche overlap was also considerable (up to 92.9 %). When comparing the northern and southern regions, there were dietary differences for L. <em>guentheri</em>, as well as significant differences in δ¹³C and δ¹⁵N values (<em>p</em> = 0.002). <em>G. bolini</em> and L. <em>guentheri</em> exhibited a generalist zooplanktivorous feeding behaviour. In addition, region seems to be a determining factor in the trophic ecology of Myctophidae.

Here, we present a comprehensive global assessment of surface ocean carbonate chemistry from 1985 to 2022, using an observation-constrained, neural-network–based CMEMS dataset. We quantify long-term trends, detect structural accelerations, and identify regions of extreme and stable carbonate conditions based on pH, aragonite saturation (Ωₐᵣ), and calcite saturation (Ω_ca). Piecewise regression analysis reveals significant accelerations in the decline of all three parameters, with breakpoints in the late 1990s (Ωₐᵣ, Ω_ca) and post-2009 (pH). Spatial trend and <em>Z</em>-score analyses (Z ≤ −2.0) indicate that the Coral Triangle and adjacent Indo-Pacific regions have experienced the most intense acidification exposure, both in trend magnitude and extreme event frequency. Concurrently, we identify chemically stable zones, defined by Ωₐᵣ ≥ 3.0 and Ω_ca ≥ 1.5, that persist in approximately 12 % of tropical ocean surface waters from 2015 to 2022. Critically, these stable zones show substantial overlap with major coral reef provinces, yet protection gaps remain. In Indonesia, the Philippines, and Papua New Guinea, less than 35 % of coral reef area falls within marine protected areas (MPAs), despite high stable zone prevalence.

This study presents an eight-year analysis (2016–2023) of landings of Pama croaker (<em>Otolithoides pama</em>), a key economic species for local livelihoods in the Gulf of Mottama, Myanmar. Using size-disaggregated data from a fish collection station operated by Mawlamyine Holding Limited, we assessed changes in population structure, seasonal landing patterns, and economic contributions. Total landings increased from 25,930 kg in 2016 to 139,618 kg in 2023; however, the number of individuals declined, indicating a shift toward the capture of larger fish, likely recruiting from earlier juvenile stages (size categories 1 and 2). Analysis of size composition further revealed a decline in juvenile recruitment in recent years. Time-series analysis showed bimodal landing peaks in June–July and December–January, likely influenced by monsoonal inputs and spawning migrations. Economic valuation estimated annual gross income per fisher between USD 1732 and USD 5692, with total fishery value reaching approximately USD 10 million annually across the Gulf. Although fisheries co-management efforts played a crucial role in increasing fish landings from 2017 through 2023, recent political instability and weakened enforcement have posed a threat to long-term sustainability, enabling the resurgence of destructive fishing practices. Our findings underscore the importance of strengthening co-management systems and restore enforcement patrols to ensure the resilience of Pama croaker stocks and the livelihoods of coastal fishing communities.</div></div>","PeriodicalId":50056,"journal":{"name":"Journal of Sea Research","volume":"207 ","pages":"Article 102610"},"PeriodicalIF":2.9,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144780552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sepetiba Bay is a coastal system heavily contaminated by PTEs. Concentrations of As, Cd, Co, Cr, Cu, Ni, Pb, Se, and Zn were analyzed in tissues and organs of crustaceans (shrimp, <em>Farfantepenaeus subtilis</em>) and bony fishes (<em>Cynoscion leiarchus, Cynoscion acoupa, Centropomus undecimalis, Plagioscion squamosissimus, Selene setapinnis,</em> and <em>Caranx hippos</em>) using an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). Copper was the element that reached the highest levels among the analyzed species/tissues/organs, followed by Zn &gt; Se &gt; As&gt;Cd &gt; Pb &gt; Cr &gt; Ni &gt; Co. Still, Zn, Cu, and Cr were present in all analyzed samples. For most species, the organs with the highest levels of PTEs were the heart and liver. The statistical results showed positive and significant correlations between the PTE concentrations of the analyzed species/tissues/organs. The Bioenrichment Factors (BF: the ratio between the levels of PTEs in the analyzed tissues/organs and the limits defined by the regulatory agencies) show that there are higher levels of PTEs than those allowed by law in the analyzed species/tissues/organs (descending order number of times higher): Cr (71), Se (35), Pb (32), Cu (23), As (13), Cd (10), Zn (7), and Co (5). For example, Cr showed relatively high BF values: <em>C. acoupa</em> (heart: 70 times; gills 9 times), <em>C. undecimalis</em> (heart 17 <em>times</em>), <em>C. leiarchus</em> (gills 13 times; heart 11 times; liver 9 times); gonads 8 times), <em>C. undecimalis (</em>gills 12 <em>times</em>), <em>P. squamosissimus</em> (gills 10 <em>times</em>) and <em>F. subtilis</em> (cephalothorax 9 times; carapace 7 times; muscle 7 times).

The gills of <em>P. squamosissimus</em> (32 times) and the gonads of <em>C. leiarchus</em> (5 times) and <em>C. acoupa</em> (4 times) indicated considerable bioaccumulation values for Pb enrichment, above the FAO/WHO (Food and Agriculture Organization/World Health Organization) limit. Therefore, this study shows a potential risk of metal contamination in the population that eats fish in the Sepetiba region. Fish is part of the traditional diet of the population living around Sepetiba Bay, primarily among low-income families who dominate the area.
