Glycosylation was conducted by mixing gelatin hydrolysates with ribose, glucose, maltose, and dextran (20 kDa) at a 1:1 mass ratio; the glycosylation products had a pH of 10 and were incubated at 80 °C for 1 h. The results showed that the glycosylation degree ranked as: ribose > glucose > maltose > dextran. The mass spectrometry analysis showed that 17, 32, and 5 glycosylation sites were identified for ribose, glucose, and maltose, respectively, suggesting a molecular weight-dependent effect. Spectroscopic analyses, including ultraviolet and infrared spectroscopy, revealed that the gelatin hydrolysate structure was expanded, with chromophores in hydrophilic environments; a blue shift in the amide A and II bands confirmed that the amino group was involved. Fluorescence spectroscopy showed conformational changes with a red shift at 303.4 nm and a reduction in intensity. Antifreeze activity, such as catalase freezing protection and shrimp surimi protein stability, and antioxidant activity, including radical scavenging and metal ion chelation, were significantly improved. Ribose exhibited the strongest effects, followed by maltose and glucose. These results demonstrate the potential of glycosylation to improve gelatin hydrolysates for functional applications.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"10 2","pages":"65-65"},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/10/2/65/pdf?version=1740397702","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silver nanoparticles (AgNPs) have a broad spectrum of antimicrobial properties and are usually produced by various green-synthesis methods. However, the application of commercialized AgNPs has not fully been clarified. Thus, the objective of this study was to evaluate the antibacterial activities of commercialized AgNPs (range of sizes 10–12 nm) on two contrasting A. salmonicida strains (I-1 and I-4), isolated from rainbow trout; the antibacterial mechanism, histopathological alterations and the expression of immune-related genes were investigated. In vitro, the minimal inhibitory concentration (MIC) was 10 µg/mL for I-1, and lowered to 9.5 µg/mL for I-4, respectively. AgNPs were shown to disrupt both the cell wall and membrane of I-1 and I-4, resulting in cell lysis and degradation. In vivo, rainbow trout challenged by immersed or intraperitoneally injected infection, the 10 µg/mL AgNP-treated groups, both showed delayed deaths and lower mortalities compared to the control groups, without any clinical signs and pathological changes. Especially for the virulent I-4, the enhanced expressions of immune-related genes TNF-α, IL-1β, IL-10 and IL-11 were significantly reduced in the AgNP-treated group, indicating a lesser inflammation due to the application of AgNPs. This study would lay theoretical foundation for the wide application of silver nanoparticles in fish diseases.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"10 1","pages":"29-29"},"PeriodicalIF":0.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/10/1/29/pdf?version=1736774356","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies on the molecular regulatory mechanisms of LZ and MT are still limited. Here, a comparative transcriptome analysis was conducted on the hypothalamus, the gonad, and the liver of golden pompano (Trachinotus ovatus) after 30 days of LZ and MT treatment, which demonstrated significant sexual size dimorphism. Following LZ treatment, the transcriptome data identified 156, 890, and 1286 different expression genes (DEGs) in the hypothalamus, the liver, and the gonad, respectively. After MT treatment, the transcriptome data identified 114, 876, and 950 DEGs in the hypothalamus, the liver, and the gonad, respectively. Functional enrichment analysis revealed that DEGs were involved in oocyte meiosis and steroid-hormone synthesis following LZ treatment. Similarly, the analysis indicated that DEGs were associated with cysteine and methionine metabolism and steroid-hormone synthesis after MT treatment. Further analysis showed that LZ treatment can promote the first meiotic division but inhibit the second meiotic division of the oocyte. MT treatment promotes polyamine synthesis to induce oocyte apoptosis, both of which affect the trajectory of ovarian differentiation in golden pompano. However, LZ and MT have converse effects in sex hormone synthesis. LZ inhibits estrogen metabolism but promotes cholesterol synthesis by regulating sqle, cyp3a40, ugt1a1, and ugt2a1, while MT promotes estrogen metabolism but inhibits the conversion of cholesterol to pregnenolone by regulating cyp19a1, cyp1a, and hsd17b7. This study reveals that both LZ and MT may inhibit the ovarian differentiation and induce masculinization through different regulatory mechanisms, which provides a fundamental insight into the sex control breeding in aquaculture.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"10 1","pages":"21-21"},"PeriodicalIF":0.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/10/1/21/pdf?version=1736223670","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cold-adapted ectotherms, such as the Arctic charr, <i>Salvelinus alpinus</i> (Linnaeus 1758), are likely to experience changes to growth as a result. Anadromous Arctic charr (charr, hereafter) are of great importance for northern communities, providing a source of income from commercial fisheries and food security from subsistence harvest. Initially, warming is expected to increase the growth of charr, benefitting subsistence and commercial fisheries in the short term. However, over longer time scales, temperatures exceeding the optimum for growth will likely result in metabolic stress, slowed growth, and higher mortality. Thus, the long-term consequences of climate change will likely be negative. We assessed anadromous charr growth from 1984 to 2013 in three stocks around Cumberland Sound using otolith measurements as proxies for age-specific growth. Trend analyses indicated growth had increased in pre-migratory ages over the years. We used mixed models to investigate changes to growth for ages 1-10 in relation to climate variables, finding that growing degree days had the greatest positive influence on ages 1-6 while annual precipitation had an overall negative effect on growth in ages 1-2 and 6-10. Contrary to previous assessments on these stocks, our results suggest charr have indeed experienced changes to growth with climate change. These findings emphasize the need for more thorough long-term growth studies in the management of fisheries as altered growth will affect food security and the economy across the Canadian Arctic.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"108 12","pages":"2087-2104"},"PeriodicalIF":1.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12615573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145539034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After spawning (and for males, after parental care), bowfin dispersed around the western half of the lake, with some fish traversing the full extent of our study area. Analysis of home range sizes revealed high variability in how widely individuals roamed, but there was a significant tendency for females to exhibit larger home ranges than males during the spring.

Some estuaries have experienced decreasing trends in catch-per-unit-effort (CPUE) of adult hardhead catfish beginning in the mid-1990s and early 2000s, and widespread decreasing trends in adult mean length were additionally observed for central and lower coast estuaries. Compared to the CPUE of finfish in the larger community, adult hardhead catfish largely exhibited decreasing trends in their relative contribution (expressed as percentage of CPUE) across most Texas estuaries. When combined with the larger Ariidae species grouping, and compared to the relative contribution of common Sciaenids, it was generally observed that the contributions of these two species groupings were converging for many estuaries. This was primarily characterized by increasing Ariidae trends. Given the trophic role of Ariidae catfishes, they clearly have the potential to exert major trophic influence on estuarine food webs.
