Ferroptosis, an iron-dependent cell death driven by lipid peroxidation, offers a new perspective for elucidating the toxicity mechanisms of MNPs. Understanding this mechanism is particularly critical for assessing and mitigating the health risks of MNPs in aquaculture. This paper provides a critical review of recent progress on MNPs-induced ferroptosis. Mechanistically, MNPs trigger ferroptosis by inducing oxidative stress and lipid peroxidation, disrupting iron homeostasis, inhibiting the GPX4 antioxidant system, and regulating signaling pathways such as Nrf2 and p53/Fosl1. Nanoscale particles may act primarily via endocytosis and intracellular interactions to induce ferroptosis, whereas microscale particles exert effects mainly through surface interactions, mechanical stress, and metabolic disruption, yet the outcome is also modulated by polymer type, surface charge, shape, aging, and protein corona formation. At the organ level, MNPs-induced ferroptosis is associated with damage to the intestine, gonads, liver, cardiovascular system, nervous system, gills, and immune organs, and is amplified by co-exposure with heavy metals and organic pollutants. For aquaculture practice, molecular markers such as MDA, GSH, and GPX4 can serve as tiered early warning indicators, with intensive pond and cage culture systems facing the highest risk. Feasible interventions include dietary antioxidant supplementation, water treatment, feed quality control, and regular replacement of aged plastic infrastructure. This review provides a theoretical basis for assessing MNPs health risks and developing practical management strategies for sustainable aquaculture.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"19 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149199020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Blue Transformation Pathway for Nigeria and Africa: A Strategic Framework for Transitioning to 90%–95% Aquaculture Dominance by 2050","authors":"Anetekhai Martins","doi":"10.1111/raq.70219","DOIUrl":"10.1111/raq.70219","url":null,"abstract":"<div>\u0000 \u0000 <p>The global fisheries sector is undergoing a structural transformation, with aquaculture surpassing capture fisheries in 2022 (51% of global aquatic animal supply) and reaching 53% by 2024, when aquaculture production topped 100 million tonnes for the first time. Despite vast aquatic resources, Africa produces only approximately 1.9% of global aquaculture output and remains dependent on declining capture fisheries. Nigeria exemplifies this imbalance: aquaculture contributes only 26% of domestic fish production, while the country faces an annual supply deficit exceeding 1.7 million metric tonnes and incurs import costs of USD 700 million–1.5 billion. This paper proposes a Blue Transformation Pathway (BTP), a phased strategic framework to transition Nigeria's fisheries sector to 90%–95% aquaculture dominance by 2050. The BTP comprises three phases: stabilization (2025–2030; ~20% aquaculture), expansion (2030–2040; ~42%), and dominance (2040–2050; 90%–95%), reflecting a smoothed 12.9% compound annual growth rate sustained across the full 28-year horizon. It is supported by seven implementation pillars, feed innovation, energy transition, infrastructure, finance, technology, human capital, and governance reform, plus three value-added pillars: blue carbon finance, knowledge economy development, and humanitarian aquaculture. Economic projections indicate potential creation of 5.9–12.6 million jobs, reduction of fish imports by up to USD 6.2 billion annually, and a GDP contribution of 5.5%–7.5% by 2050, with additional gains from Sargassum utilization. The study concludes that Nigeria's aquaculture transition is feasible and scalable, offering a replicable model for sustainable fisheries transformation across Africa.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"19 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149077644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review synthesises and advances current understanding by integrating physiological, biochemical, and molecular evidence on the effects of elevated temperature and diverse contaminants—including endocrine-disrupting chemicals (EDCs), heavy metals (HMs), nanoparticles (NPs), pesticides, and microplastics—on crustacean reproduction and immunity. We summarise the molecular mechanisms underlying thermal- and pollutant-induced disruptions to gametogenesis, endocrine signalling, gonadal development, oxidative homeostasis, and innate immune pathways. To provide mechanistic insight into these processes, structure-based molecular docking analyses were applied in this review to evaluate the interactions of 18 environmentally relevant contaminants—including EDCs and pesticides known to impair crustacean health—with key reproductive regulatory nuclear receptors (EcR, RXR, ERR) across commercially important crustaceans including crabs, shrimps, and lobsters. In addition, interactions of HMs and NPs with these nuclear receptors, as well as with the detoxification protein metallothionein, were examined using the mud crab <i>Scylla paramamosain</i> as a representative model species. These structure-based evaluations suggest a potential molecular framework linking endocrine disruption, metal sequestration, and immunotoxicity in crustaceans. We further synthesise current knowledge on endogenous protective responses, including antioxidant defences and metallothionein (MT)-mediated detoxification, and assess potential mitigation strategies. Despite recent advances, critical knowledge gaps remain, particularly regarding the combined and synergistic effects of multiple environmental stressors.

This study applied a meta-analytical approach to evaluate the effects of dietary chitin-containing ingredients and dietary chitin content on fish growth performance and nutrient digestibility, and to develop regression models identifying factors influencing fish responses to chitin. The pooled effects indicated that the dietary inclusion of krill, shrimp, and yeast improved fish growth without affecting feed intake, whereas insect-based diets reduced growth, and insects and yeast reduced nutrient digestibility. However, these overall effects varied across fish trophic levels. Notably, insect-based diets decreased growth in higher trophic species but promoted growth in lower trophic species. Meta-regression analysis showed that dietary chitin content partly explained the heterogeneity in effect sizes for growth performance and protein digestibility in insect-based diets. Segmented regression showed a marked decline in fish growth above 2.91% dietary insect chitin. Multiple regression models indicated that trophic level and study duration influenced fish growth responses to dietary insect chitin, while initial body weight affected nutrient digestibility responses to chitin. At comparable study durations, lower dietary chitin contents maintained stable growth across trophic levels, whereas growth declined progressively with increasing chitin levels, with the steepest reductions observed in higher trophic species. These findings demonstrate that dietary chitin content, trophic level, study duration and initial body weights are key factors shaping fish responses to chitin, providing a quantitative basis for optimizing chitin-containing ingredients inclusion in aquafeeds.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"19 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149077647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large yellow croaker iridovirus (LYCIV) is a major pathogen of this species, and the innate immune response constitutes the primary line of defense.

As a result, the government of Kenya promoted aquaculture through an economic stimulus program and achieved significant milestones in the sector's development over the last decades. However, aquaculture still faces a myriad of challenges in the area of feeds. Fish feed accounts for nearly 50% of the overall production expenses and is primarily imported despite the availability of local resources to spur aquaculture development. Among the opportunities for the growth of fish feed and aquaculture industry include the availability of fish feed ingredients, a youthful workforce, and various production technologies. The information disconnect between available resources and opportunities has limited youth recruitment into the sector. To bridge this gap, the study conducted interviews with key informants coupled with a literature survey to establish the distribution of locally available fish feed ingredients, technologies, constraints, and opportunities for aquaculture development. Findings revealed that the country's demand for fingerlings and fish feed estimates stand at 100 million and 100,000 MT. Available local fish feed ingredients can potentially produce between 141,200 and 470,667 tons annually, assuming different levels of competition from other sectors such as animal feed production that utilize the same ingredients.

The sector faces ongoing challenges, including high energy consumption, land-use conflicts, and unreliable electricity supply, all of which impede its sustainable development and pose broader risks to both human survival and long-term ecological balance. The quest for efficient solar energy utilization has led to the emergence of aquavoltaics, a novel integrated model that combines photovoltaic technology with aquaculture. Aquavoltaics offers a promising solution to mitigate climate change while addressing the growing global demands for food and energy. By installing photovoltaic modules on water surfaces, aquavoltaic systems simultaneously generate renewable energy and support aquaculture operations. This integration enhances land and water resource efficiency, providing stable power for critical aquaculture equipment and improving the overall sustainability of the sector. Moreover, it contributes to mitigating the energy crisis, enhancing water quality, and advancing the synergistic development of energy and aquaculture within the water-energy-food nexus. This review paper explores the current state of aquaculture production and energy consumption, detailing the functionality of aquavoltaic systems, their impact on water quality parameters, and their influence on the productivity of cultured organisms. Additionally, the paper discusses how aquavoltaics fulfill the water-energy-food nexus, offering insights into improving aquaculture production and clean energy.

Although the liver of teleosts is not considered a primary osmoregulatory organ and its contribution to osmoregulation is frequently overlooked, it in fact plays an indispensable role in fish adaptation to salinity changes through its involvement in energy supply and allocation, ion transport, signal transduction, immune response, and cellular structural regulation. Central to the energy-related function, the liver regulates glucose and lipid turnover to fuel osmotic stress responses. Beyond energy provision, hepatocytes also participate in water, ion, and organic osmolyte (e.g., urea, taurine) trafficking via regulated expression of aquaporins (AQPs) and transmembrane transporters. The liver further contributes to osmotic signal transduction through the expression of cell adhesion molecules, ion channel receptors, and ion channel regulatory proteins, enabling the propagation and amplification of salinity stress signals. Moreover, it participates in regulating the expression of inflammatory factors and antioxidant enzymes, metabolic reallocation, and protein homeostasis, helping teleosts maintain immune homeostasis under osmotic stress, optimize energy allocation between immune and osmotic regulation, and reduce cellular damage, thereby adapting to salinity changes. Building upon a decade of research advances in hepatic osmoregulatory mechanisms, this review systematically synthesizes the liver's multifaceted roles in teleost salinity adaptation, including glucolipid metabolic reprogramming, osmosensory signaling, cytoskeleal remodeling, and hormonal coordination. We further compare the water-electrolyte balance strategies employed by different ecological types of teleosts, while offering forward-looking insights into future research directions for sustainable aquaculture: (1) using multi-omics and gene editing to identify and integrate key genes regulating hepatic metabolism and osmotic adaptation into breeding programs; (2) elucidating interactions between hepatic energy metabolism and organic osmolytes (e.g., taurine, betaine) for developing targeted nutritional strategies; (3) identifying the research gaps in hepatic urea-based osmoregulation of teleosts.</p>\u0000 </div>","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"19 1","pages":""},"PeriodicalIF":13.8,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It impairs growth, feed intake, tissue integrity, immune homeostasis, and survival, making hypoxia tolerance a key trait for sustainable production. At the physiological level, tolerance reflects a balance between survival and cost, involving metabolic suppression, altered development, immune dysregulation, and reduced resilience under compound stress. At the molecular level, hypoxia responses are organized around hypoxia-inducible factor-1α (HIF-1α) and related HIF-α isoforms, whose activity depends on oxygen-dependent hydroxylation, VHL-mediated degradation, FIH-dependent transcriptional restraint, and oxygen-independent inflammatory/pathogen-associated inputs, metabolic and epigenetic regulation, RNA-level control, SET7-mediated protein methylation, OTUB1-related ubiquitin-linkage control, and redox-mediated crosstalk with the PHD-HIF axis. This review evaluates nutritional strategies for hypoxia tolerance by distinguishing direct HIF evidence, indirect HIF-related evidence, and phenotype-based evidence. A three-tier evidence framework is used to interpret protein and amino acid, carbohydrate, lipid, vitamin, mineral, plant-derived additive, probiotic/prebiotic/postbiotic, and carotenoid interventions. We emphasize that improved hypoxia tolerance should not be equated with direct activation of HIF-1α unless protein stabilization, nuclear localization, HRE activity, target-gene regulation, or functional perturbation evidence is available.

This review discusses the existing knowledge on heart remodeling in finfish aquaculture and its importance for fish performance. Here, we described the morphological deviations in size, form, and structure of the hearts of farmed fish relative to their wild conspecifics that were statistically supported by meta‐analysis, including a general rounding of the heart and alterations in its symmetry, especially for salmonid species. To get to the heart of these cardiac alterations, we also reviewed how aquaculture practices, focusing on factors related to genetics, environmental conditions, nutrition, disease, and stress, have changed the cardiac morphology of farmed fish. When looking into implications on cardiac performance, the aquaculture‐induced cardiac plasticity seems either beneficial or pathological. Overall, this review highlights the propensity of aquaculture practices to cause changes in heart morphology, but understanding the functional consequences and underlying mechanisms of these alterations necessitates comprehensive, integrated research that considers the intricate interactions among genetic, environmental, and physiological influences.","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"14 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149009762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
