A total of 450 crayfish (3.94 ± 0.03 g) were selected and randomly divided into six groups, with each group consisting of three replicates and 25 crayfish per replicate. The crayfish were fed a basal diet without attractant (control group) and five experimental diets supplemented with 0.4% betaine (BET), 0.4% trimetlylamine oxide (TMAO), 0.4% squid paste (SQU), 0.4% dimethyl-β-propiothetin (DMPT), and 0.4% taurine (TAU). The feeding trial lasted for 6 weeks. The results showed that compared with the control group, the BET, SQU, DMPT, and TAU groups significantly improved in growth performance, weight gain rate, and specific growth rate of crayfish. Compared with the control group, the BET, MTAO, and SQU groups significantly increased hepatopancreas SOD, CAT, and T-AOC. Histological results showed that compared with the control group, all feeding attractant groups could alleviate hepatopancreas tissue damage. Compared with the control group, the TMAO and SQU groups significantly reduced serum GLU content as well as ACP and AKP activities. The results of gene quantitative analysis showed that, compared with the control, TMAO significantly upregulated the expression of tlr, nf-kb, propo, hsp70, and tgf-β, while TAU significantly increased the expression of hsp70, hsp90 and nf-kb genes. Compared with the control group, the expression levels of tor, 4ebp1, and s6k1 in the TMAO group were significantly increased. Compared with the control group, the expression levels of leptin and npy genes in the DMPT group were significantly increased. In summary, the addition of attractants to high plant protein feed has the effects of promoting growth, enhancing antioxidant capacity, improving digestive enzyme activity, alleviating hepatopancreas injury, improving immunity, and promoting feeding.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"11 5","pages":"267-267"},"PeriodicalIF":0.0,"publicationDate":"2026-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147878918","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}

Juvenile fish (initial weight 24.01 ± 1.35 g) were fed one of six isonitrogenous and isolipidic diets containing graded levels of TB (0–1.5 g/kg) for 90 days. Supplementation significantly enhanced the weight gain and specific growth rates. The optimal level of 0.9 g/kg TB improved muscle nutritional quality, muscle texture, and intestinal morphology. This dosage also significantly increased hepatic and intestinal antioxidant capacity, elevating superoxide dismutase (SOD), catalase (CAT), and total antioxidant capacity (T-AOC), while reducing malondialdehyde (MDA) content. Furthermore, dietary TB at 0.9 g/kg reduced plasma and hepatic triglycerides and total cholesterol, and elevated key plasma immune parameters, including complement components (C3, C4) and phosphatase activities (ACP, AKP). Intestinal health was further enhanced, as evidenced by increased digestive enzyme activities (amylase, lipase, chymotrypsin) and improved microbial diversity, marked by a proliferation of beneficial bacteria. In conclusion, dietary TB supplementation at 0.9 g/kg optimally promotes growth, improves muscle and intestinal health, and enhances antioxidant and immune functions in H. otakii.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"11 1","pages":"67-67"},"PeriodicalIF":0.0,"publicationDate":"2026-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/11/1/67/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904805","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}

Phylogenetic and collinearity analyses indicated that TTC39 genes are evolutionarily conserved among Danio rerio. Gene structure and motif analyses further highlighted the homology and distributional diversity within the TTC39 family. Quantitative expression assays comparing red and black skin revealed significant upregulation of TTC39A and TTC39B in red skin, suggesting that these genes play a role in regulating skin color.

The NPFF precursor encodes two mature peptides, NPFF and NPAF (neuropeptide AF). Both peptides share the conserved C-terminal PQRFa motif. However, there is very limited information available on receptor cross-reactivity for NPFF and GnIH peptides in teleosts. As a first step, we cloned two cognate receptor genes for NPFF, designated as NPFFR2-1 and NPFFR2-2, in the flatfish species half-smooth tongue sole. Tissue distribution analysis revealed that npffr2-1 and npffr2-2 transcripts were present at high levels in the brain and pituitary gland, and at lower levels in some peripheral tissues. In vitro functional analysis indicated that NPFF significantly stimulated CRE-luc and SRE-luc activity in COS-7 cells expressing either NPFFR2-1 or NPFFR2-2. However, NPAF increased CRE-luc and SRE-luc activity only via NPFFR2-1. Moreover, NPFF exerted an inhibitory effect on NFAT-RE-luc activity in COS-7 cells transfected with NPFFR2-1, whereas NPAF elicited an evident stimulatory effect via NPFFR2-2. Neither GnIH1 nor GnIH2 altered CRE-luc activity in COS-7 cells transfected with NPFFR2-1 or NPFFR2-2; however, forskolin-induced CRE-luc activity was significantly reduced by these two peptides. Furthermore, neither basal nor forskolin-stimulated CRE-luc activity was modified by NPFF or NPAF in COS-7 cells expressing the GnIH receptor (GnIHR). Both GnIH1 and GnIH2 significantly increased SRE-luc activity in COS-7 cells expressing NPFFR2-1 or NPFFR2-2, and vice versa. Taken together, our findings provide novel evidence that both NPFF and GnIH peptides could exert their functions via three different receptors, and that PKA, PKC, and Ca2+ signaling pathways are potential mediators.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"11 1","pages":"40-40"},"PeriodicalIF":0.0,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/11/1/40/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917915","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, limited information exists regarding the tolerance and adaptability of red tilapia (Oreochromis spp.) to alkaline environments. This study evaluated the acute semi-lethal toxicity of alkaline water and its physiological effects on juvenile red tilapia (44.80 ± 1.09 g; 12.84 ± 1.02 cm). Fish were exposed to NaHCO3 for 96 h at five alkalinity levels (50, 55, 60, 65, and 70 mmol/L). Survival declined significantly with increasing alkalinity, and the 96 h LC50 was 60.66 mmol/L, indicating relatively high alkaline tolerance. Gill tissue and serum samples were collected at 0, 12, 24, 48, and 96 h under 50 mmol/L NaHCO3 and freshwater (control). Under prolonged alkaline exposure, gill structure exhibited marked alterations, with SLL and ILCMT progressively decreasing over time. Serum antioxidant responses were impaired, showing a sustained decline in SOD activity and a rise in MDA content, indicating the onset of oxidative stress. TAOC, CAT, and GSH-Px displayed a biphasic response, rising initially before declining with continued stress. TP and GLU levels remained largely stable throughout. Energy metabolism indices also shifted dynamically: TC showed a transient increase followed by a decrease, whereas TG and LDH initially declined before rising later in the exposure period. Stress-related markers, including cortisol, T3, ALP, and ACP, were notably elevated during the exposure. Additionally, serum ion concentrations (K+, Ca2+, Na+, Cl−) increased gradually over the 96 h period, reflecting progressive osmoregulatory disturbance under alkaline stress. Overall, this study shows that juvenile red tilapia (Oreochromis spp.) have high alkaline tolerance (96 h LC50 = 60.66 mmol/L NaHCO3), but exposure to alkaline water causes significant physiological stress, affecting gill structure, antioxidant defense, metabolism, and ion balance. These results offer valuable insights into their adaptability to saline-alkaline aquaculture.","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"11 1","pages":"26-26"},"PeriodicalIF":0.0,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2410-3888/11/1/26/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895822","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}

We conducted a mark-recapture study in a 400 m reach of Lee Creek in Alberta, Canada, using passive integrated transponder and visible implant elastomer tags across approximately 4 months. Boosted regression tree models were used to assess the movement of (1) all recaptured individuals (global model) and (2) only mobile individuals (movement only model) in response to abiotic and biotic factors. Biotic factors, such as congeners at the destination (8.7%), congeners at the origin (8.0%), and competitors at the origin (7.2%) were the most important variables for predicting movement in the global model. Alternatively, cobble (18.7%) followed by biotic factors including congeners at the origin (9.6%) and competitors at the origin (9.1%) were the most important variables selected in the movement only model. Biotic and abiotic factors showed strong interactions, providing a clear example of the importance of competition in the understanding of movement. Although the vast majority of restoration activities for endangered species are aimed at abiotic (i.e. habitat-related) factors, this study shows how these may be limited without considering biotic interactions, such as the role of inter- and intraspecific competition.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10641-026-01841-9.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"109 2","pages":"86"},"PeriodicalIF":1.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13152878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147867267","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}

We used littoral and pelagic ecotypes of pumpkinseed sunfish (<i>Lepomis gibbosus</i>) to investigate performance over the natal summer of age-0 juveniles spawned either in the ancestral littoral habitat of a Canadian shield lake or in two other habitat types: exposed rocky littoral shorelines and submerged rocky shoals offshore in the pelagic habitat. We compared zooplankton availability and use through stable isotope analysis of juvenile tissue and subsequent effects on late natal summer size and condition among habitats. Zooplankton prey were three times more abundant at pelagic than at littoral and shoreline sites and stable isotope analysis revealed that the fraction of plankton-derived tissue was consistently higher in age-0 juvenile fish from pelagic sites. By summer's end, age-0 pelagic juveniles were 15% longer and 35% heavier than littoral and shoreline juveniles, indicating that accessible planktonic resources provided significant growth benefits to juveniles in the pelagic but not inshore habitats. By addressing a key uncertainty about the effects of non-ancestral natal conditions on age-0 performance, our study reveals a previously unrecognized juvenile benefit of habitat diversification by pumpkinseed sunfish in a postglacial lake. Since larger juvenile size contributes to first year survival these benefits could enhance local recruitment to a pelagic subpopulation that favours ecological and phenotypic diversification of pumpkinseed ecotypes through interacting developmental and evolutionary mechanisms.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10641-026-01836-6.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"109 2","pages":"65"},"PeriodicalIF":1.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13033004/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147580892","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}

The human need for this infrastructure is generally prioritised over its environmental impact, particularly for aquatic fauna with migratory needs. Such infrastructure can block migratory pathways for fish, trap sediment, and alter river flow regimes. The Lower Thukela Bulk Water Supply Scheme (LTBWSS) abstraction weir was constructed on the lower uThukela River in KwaZulu-Natal Province, South Africa, in 2017, near the town of Mandini. The riverine stretch where it is constructed is a critical interface for marine, estuarine, and freshwater migrant local fish species. As such, a vertical-slot fishway was incorporated into its design to facilitate the movement of fish over the weir. This study utilised data collected from field surveys at three sites upstream of the weir, four sites downstream of it, and two sites on the Mandini Stream, a tributary of the uThukela, to assess the impact of the weir on local fish community structures. Multivariate statistical analyses were employed to identify the environmental variables influencing fish community structures and select fish species in the region. The results showed that the dominant cover types, dominant substrate, average depth, and water temperature significantly affected fish communities in the study. Individual species were driven by different habitats, water velocity-depth profiles, and physical water-quality variables. Furthermore, the presence of the LTBWSS has influenced three cichlid species, particularly <i>Tilapia sparrmanii,</i> which was previously shown to favour silt substrate. The resulting loss of downstream sedimentation because of the LTBWSS weir has led to the absence of the species, along with synergistic effects on water quality and quantity in the downstream sections of the uThukela River.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10641-026-01822-y.</p>","PeriodicalId":11799,"journal":{"name":"Environmental Biology of Fishes","volume":"109 1","pages":"54"},"PeriodicalIF":1.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12960327/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147376517","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}
