Copper, an essential micronutrient in crustaceans, plays vital roles in enzymatic processes, oxygen transport, pigmentation, and structural protein synthesis, including collagen and elastin. Recent research has elucidated its pivotal role in innate immunity of crustaceans, enhancing the immune response by promoting phagocytic activity, antimicrobial peptide production, and modulation of immune gene expression. Copper ions exhibit antimicrobial effects by disrupting cell membranes and inhibiting microbial proliferation. Furthermore, copper governs antioxidant defense mechanisms, protecting crustaceans against oxidative stress and infection. However, excessive copper can lead to toxicity, highlighting the need for strict maintenance of copper homeostasis. This review explores the complex processes of copper homeostasis in crustaceans, detailing transport mechanisms, storage proteins, and detoxification pathways. It emphasizes copper's critical physiological and immunological functions, contributing to a comprehensive understanding of its multifaceted roles in crustaceans and laying groundwork for further exploration of copper homeostasis as a strategy for boosting crustacean immunity. Aquaculture practices significantly influence copper levels in crustaceans. Effective copper management, including monitoring techniques, water treatment strategies, and regulatory frameworks, is crucial for both crustacean welfare and environmental sustainability.
铜是甲壳动物必需的微量营养元素,在酶过程、氧运输、色素沉着和结构蛋白合成(包括胶原蛋白和弹性蛋白)中发挥着重要作用。最近的研究阐明了铜离子在甲壳动物先天免疫中的关键作用,它通过促进吞噬活性、抗菌肽的产生和免疫基因表达的调节来增强免疫反应。铜离子通过破坏细胞膜和抑制微生物增殖来发挥抗菌作用。此外,铜还能调节抗氧化防御机制,保护甲壳动物免受氧化应激和感染。然而,过量的铜会导致中毒,因此需要严格维持铜的平衡。这篇综述探讨了甲壳动物体内铜平衡的复杂过程,详细介绍了运输机制、储存蛋白和解毒途径。它强调了铜的关键生理和免疫功能,有助于全面了解铜在甲壳动物中的多方面作用,并为进一步探索铜平衡作为提高甲壳动物免疫力的策略奠定基础。水产养殖方法会极大地影响甲壳类动物体内的铜含量。有效的铜管理,包括监测技术、水处理策略和监管框架,对于甲壳动物的福利和环境的可持续发展至关重要。

Cell death mechanisms in crustaceans are a complex interplay of processes essential for maintaining cellular homeostasis and immune defense. Modes of cell death like apoptosis, necroptosis, and necrosis are well-documented in crustaceans, serving crucial roles in removing damaged or infected cells. Unlike in other organisms, crustaceans likely lack pyroptosis, a type of programmed cell death associated with innate immunity and inflammation, because they do not possess the gasdermin genes essential for this process. Recently, NETosis and ferroptosis have emerged as significant mechanisms in pathogen defense. NETosis, involving the release of DNA fibers and antimicrobial proteins, helps trap and neutralize pathogens, while ferroptosis, an iron-dependent form of cell death, contributes to lipid peroxidation and immune responses. Cuproptosis, although not yet studied in the context of crustacean immunity, shows potential crosstalk with ferroptosis, particularly in the regulation of metal ion homeostasis, oxidative stress, and cellular metabolism. Understanding these mechanisms offers promising applications in aquaculture, such as developing targeted immune modulators and enhancing disease resistance in economically important crustacean species.
甲壳动物的细胞死亡机制是一个复杂的相互作用过程,对维持细胞平衡和免疫防御至关重要。细胞凋亡、坏死和坏死等细胞死亡模式在甲壳类动物中已得到充分证明,它们在清除受损或受感染细胞方面发挥着至关重要的作用。与其他生物不同的是,甲壳类可能缺乏热凋亡,这是一种与先天免疫和炎症相关的程序性细胞死亡,因为它们不具备这一过程所必需的气体蛋白基因。最近,NETosis 和 ferroptosis 成为病原体防御的重要机制。NETosis涉及DNA纤维和抗菌蛋白的释放,有助于捕获和中和病原体,而ferroptosis是一种依赖铁的细胞死亡形式,有助于脂质过氧化和免疫反应。尽管尚未对杯突症进行甲壳动物免疫方面的研究,但它与铁突症之间存在潜在的相互影响,特别是在调节金属离子平衡、氧化应激和细胞代谢方面。了解这些机制为水产养殖业提供了广阔的应用前景,例如开发有针对性的免疫调节剂和增强具有重要经济价值的甲壳类物种的抗病能力。

Distant hybridization and gynogenesis are two prevalent breeding techniques for fishes. Drawing from the research achievements of our team and the existing literature, we summarize the reproductive traits and genetic features of fishes derived from distant hybridizations and gynogenesis, and we deduce the fundamental mechanisms of these two methods and compare them, discerning their common and different characteristics. Both distant hybridization and gynogenesis techniques can alter genotypes and phenotypes, thus establishing them as significant breeding methods. Additionally, the genetic principles and the basic biological characteristics of distant hybridization and gynogenesis in fish have been inferred. We propose the concepts of macro‐hybrid and micro‐hybrid based on extensive experimental findings from fish distant hybridizations and gynogenesis. The term “macro‐hybrid” refers to offspring from distant hybridization that possess two distinct subgenomes, each inherited from one of the two parental species, such as allodiploid and allotetraploid lineages. The concept of “micro‐hybrid” refers to offspring, including autodiploid and autotetraploid lineages, as well as those resulting from artificial gynogenesis, whose genome almost originates solely from the maternal parent but in which certain DNA fragments derived from the paternal parent insert. Distant hybridization and gynogenesis are vital techniques in fish genetics, breeding, and evolution. We highlight the prospective paths for research and application of distant hybridization and gynogenesis in fishes.
远缘杂交和雌核发育是鱼类育种的两种常用技术。我们结合本团队的研究成果和现有文献,总结了远缘杂交和雌核发育所产生的鱼类繁殖性状和遗传特征,推导了这两种方法的基本机制,并对它们进行了比较,找出了它们的共同点和不同点。远缘杂交和雌核发育技术都能改变基因型和表型,因而是重要的育种方法。此外,我们还推断了鱼类远缘杂交和雌核发育的遗传原理和基本生物学特征。根据鱼类远缘杂交和雌核发育的大量实验结果,我们提出了宏杂交和微杂交的概念。所谓 "大杂交",是指远缘杂交的后代具有两个不同的亚基因组,每个亚基因组遗传自两个亲本中的一个,如异源二倍体和异源四倍体系。微杂交 "的概念是指后代,包括自二倍体和自四倍体系,以及人工雌核发育产生的后代,其基因组几乎完全来自母本,但其中插入了父本的某些 DNA 片段。远缘杂交和雌核发育是鱼类遗传学、育种和进化的重要技术。我们重点介绍了鱼类远缘杂交和雌核发育的研究和应用前景。

Global aquaculture production has been rising for several decades, with up to 76% of the total production from fish. However, the problem of fish diseases is becoming more and more prominent in today's context of pursuing sustainable aquaculture. Since the first fish genome assembly reported in 2002, genomic approaches have been successfully implemented in fish breeding to enhance disease resistance and reduce economic losses caused by diverse fish diseases. Here, we present a review of the current progress in fish genomics and its application in disease‐resistance breeding. First, assembly data for all publicly available fish genomes were curated and statistical analysis of these data were performed. Subsequently, genomics‐assisted breeding approaches (including quantitative trait loci mapping, genome‐wide association study, marker‐assisted selection, genomic selection, gene transfer, and genome editing) that have been applied in practical disease–resistance breeding programs are outlined. In addition, candidate genetic markers that could possibly be utilized in breeding were summarized. Finally, remaining challenges and further directions were discussed. In summary, this review provides insight into fish genomics and genomics‐assisted breeding of disease‐resistant fish varieties.
几十年来,全球水产养殖产量不断上升,鱼类产量占总产量的 76%。然而,在当今追求可持续水产养殖的背景下,鱼病问题日益突出。自 2002 年首次报道鱼类基因组组装以来,基因组学方法已成功应用于鱼类育种,以提高抗病能力,减少各种鱼病造成的经济损失。在此,我们回顾了当前鱼类基因组学的进展及其在抗病育种中的应用。首先,我们整理了所有公开鱼类基因组的组装数据,并对这些数据进行了统计分析。随后,概述了已应用于实际抗病育种计划的基因组学辅助育种方法(包括数量性状位点图、全基因组关联研究、标记辅助选择、基因组选择、基因转移和基因组编辑)。此外,还总结了可能用于育种的候选遗传标记。最后,讨论了仍然存在的挑战和进一步的发展方向。总之,本综述为鱼类基因组学和基因组学辅助抗病鱼类品种的培育提供了深入的见解。

<p>The health and well-being of all people—<i>including all those persons reading this editorial</i>—depends by a very large extent upon the nutrient content of their diet or food that they regularly consume. It is not surprising therefore that nutrition-related disorders still remain the number one preventable health challenge facing all countries globally: over 735 million people suffering from hunger and under-nutrition in 2022, and over-nutrition and obesity, and resulting metabolic disorders such as coronary heart disease, diabetes and hypertension, resulting from the increased consumption of fast foods and processed meat products, affecting over 890 million adults in 2022 [<span>1</span>].</p><p>Notwithstanding the above global crisis, aquatic food products, whether derived from aquaculture or wild capture fisheries, offer a much healthier alternative to fast foods, highly processed foods and terrestrial meats [<span>2</span>]. Aquatic foods include freshwater and marine fish, crustaceans, molluscs, and several other invertebrate species, such as sea urchins, sea cucumbers, sea squirts, marine worms, as well as aquatic plants, seaweeds, and algae. According to the latest statistical information from the FAO, total global aquaculture production in 2022 reached a new high of 130.92 million tonnes (Mt, live weight) and was valued at $312.75 billion, with the total global production increasing at a compound annual growth rate of 5.19% per year since 2000. By contrast, landings from capture fisheries have remained relatively static since 2000, decreasing from 94.78 Mt in 2000 to 92.29 Mt in 2022, with total global production from aquaculture and capture fishery landings increasing to a new high of 223.21 Mt in 2022 [<span>3</span>]. Seafood currently contributes 14.79% of total animal protein consumed globally; however, great variety of contribution is notable across countries and continents, with values higher than 20% in Asia and about 5% in North and South American countries (Table 1) [<span>4</span>]. Increased consumption of aquatic foods (blue foods) is commonly advocated from various viewpoints and considerations, including environmental as well as health-related factors [<span>5</span>].</p><p>In fact, in contrast to traditional capture fisheries, aquaculture offers a series of added advantages, including the ability to significantly increase global fish and seafood production and market availability, reducing harvesting pressure on wild stocks, and thus potentially benefiting biodiversity, and, in the case of fed-aquaculture fish and crustacean species, the unique and so far not fully utilized potential to tailor the nutrient profile of the target species to the consumer, through feed ingredient selection and sustainable feed use. By doing so, aquaculture can maximize the potential health value and benefit of farmed aquatic food products to the consumer.</p><p>With this in mind, we believe there is significant value in exploring new res
所有人--包括阅读这篇社论的所有人--的健康和福祉在很大程度上取决于他们的饮食或经常食用的食物中的营养成分。因此,营养相关疾病仍然是全球所有国家面临的头号可预防健康挑战就不足为奇了:到 2022 年,将有超过 7.35 亿人遭受饥饿和营养不足之苦;到 2022 年,将有超过 8.9 亿成年人因快餐和加工肉制品消费量增加而营养过剩和肥胖,并由此引发冠心病、糖尿病和高血压等代谢性疾病[1]。尽管存在上述全球危机,但水产食品,无论是来自水产养殖还是野生捕捞,都为快餐、高度加工食品和陆地肉类提供了更健康的替代品[2]。水产食品包括淡水鱼和海水鱼、甲壳类动物、软体动物和其他一些无脊椎物种,如海胆、海参、海鞘、海洋蠕虫,以及水生植物、海藻和藻类。根据粮农组织的最新统计信息,2022年全球水产养殖总产量达到1.3092亿吨(百万吨,活重)的新高,总价值为3127.5亿美元,自2000年以来,全球总产量以每年5.19%的复合年增长率增长。相比之下,捕捞渔业上岸量自 2000 年以来保持相对稳定,从 2000 年的 9478 万吨下降到 2022 年的 9229 万吨,而水产养殖和捕捞渔业上岸量的全球总产量则增加到 2022 年的新高 22321 万吨[3]。目前,海产品占全球动物蛋白总消费量的 14.79%,但各国和各大洲的比例差异显著,亚洲高于 20%,北美和南美国家约为 5%(表 1)[4]。增加水产食品(蓝色食品)的消费通常是出于各种观点和考虑,包括环境和健康相关因素[5]。国家/地区水产食品(千克/瓶/年)占动物蛋白总量的百分比陆生肉类(千克/瓶/年)占动物蛋白总量的百分比奶类(千克/瓶/年)占动物蛋白总量的百分比蛋类(千克/瓶/年)占动物蛋白总量的百分比总计非洲9.6117.6517.7850.0935.2022.312.254.4694.51Asia24.2020.3333.4543.1068.4421.4911.3910.8895.80Europe21.718.9677.6448.05200.9233.7813.916.3097.09Caribbean9.307.8045.4661.6982.4519.817.136.8196.11Central America11.937.1366.9958.37111.5619.4617.9311.2696.22Northern America22.185.73122.7760.82224.4126.9515.805.9199.41South America9.664.7384.5564.21111.5619.4617.9311.2699.66Oceania22.599.6291.2061.37147.3621.256.763.3795.61World20.1614.7943.1248.6087.5924.0910.418.6996.17 事实上,与传统的捕捞渔业相比,水产养殖具有一系列额外优势,包括能 够显著增加全球鱼类和海产品产量和市场供应,减少对野生种群的捕捞压力, 从而可能有利于生物多样性,对于投喂水产养殖的鱼类和甲壳类物种,通过饲料 成分选择和可持续饲料使用,具有独特的、迄今尚未充分利用的潜力,可根据 消费者的需求量身定制目标物种的营养成分。有鉴于此,我们认为探索水产养殖科学的新研究领域和目标具有重要价值。具体来说,我们的目标不仅是以可持续的方式提高海产品产量,使全世界人民在地理和经济上更容易获得海产品,而且还要探索提高养殖物种营养成分的方案,使消费者更好地受益。例如,在面临微量营养素缺乏症的地区,量身定制的水产养殖生产系统可以帮助缓解这些问题。这种方法要求我们转变观念,从仅仅将水产养殖视为生产公斤级海产品的手段,转变为将其视为一个能够在需要的地方提供特定数量的必需和有益营养素的系统。我们相信,这一修订后的目标不仅可能惠及全球营养不良人口,为实现可持续发展目标2 "零饥饿 "做出贡献,还将提升整个水产养殖行业。事实上,更加注重伦理道德,努力提高海产品生产的营养水平,也有助于扩大水产养殖的社会接受度,促进水产养殖被公认为全球粮食系统中可持续、可扩展、公平和营养有效的支柱。 在这篇社论的最后,我们想与大家分享最新的技术信息并表示感谢。从 2025 年开始,《水产养殖评论》将过渡到连续出版。这一变化符合行业趋势,预计将受到作者和读者的欢迎,因为它可以加快从录用到出版的周转速度,从而更快、更有效地传播知识。然而,这一转变将影响我们继续提供翻译摘要的能力。事实上,水产养殖是一个真正的全球性产业,生产者遍布各个国家,其中许多国家并不主要使用英语。认识到这一点后,《水产养殖评论》一直率先提供多种语言的翻译摘要,包括中文、阿拉伯文、西班牙文和巴西/葡萄牙文。遗憾的是,随着连续出版物的发展,这项服务将不再可行。不过,由于最近在线翻译工具的效率和可用性不断提高,我们相信,任何对水产养殖感兴趣的人,即使是英语水平有限的人,仍然能够阅读和理解我们的论文摘要。我们衷心感谢伊齐亚-埃斯滕索罗博士、埃斯特-莱亚尔-塞布里安博士、拉沙-M-雷达教授、丹尼尔-莱莫斯教授、玛丽亚-塞利亚-波尔泰拉教授和刘家寿教授,感谢他们在为我们翻译论文摘要方面提供的卓越支持,他们也是《水产养殖学报》编辑委员会非常宝贵和活跃的成员。我也非常高兴和荣幸能与阿尔伯特(AGJT)共同撰写这篇简短的社论。作为本刊的创始人,艾伯特的远见卓识、满腔热情和对本行业坚定不移的支持是非常宝贵的。我(GMT)非常感谢艾伯特对全球水产养殖界的指导、传帮带和坚定承诺。我和艾伯特希望您喜欢本期的《水产养殖评论》。

By doing so, aquaculture can maximize the potential health value and benefit of farmed aquatic food products to the consumer.&lt;/p&gt;&lt;p&gt;With this in mind, we believe there is significant value in exploring new res","PeriodicalId":227,"journal":{"name":"Reviews in Aquaculture","volume":"16 4","pages":"1461-1462"},"PeriodicalIF":8.8,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/raq.12965","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142161044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The immense production of fishmeal and fish oil is dramatically intensifying the severe state of pelagic fisheries overexploitation. The latter in conjunction with the increasing demand for low-cost protein-rich food supply prompt aquaculture to employ new practice. Several novel dietary ingredients are currently under evaluation for potential incorporation in aquafeeds in an effort to shift the aquaculture sector toward a more sustainable and economic production. The present review aims to summarize the existing findings regarding the effects of studied alternatives to fishmeal and fish oil on the most valuable and commercially produced marine (Sparus aurata and Dicentrarchus labrax) and freshwater (Salmo salar and Oncorhynchus mykiss) finfish species in European aquaculture. Alternative protein sources, including macroalage (marine plants), krill (marine fishery), insects (terrestrial), terrestrial animal by-products (processed/rendered), and single cell ingredient (biotechnology), are discussed for their efficiency in promoting the growth and the welfare of both fry and adult cultured finfish species. Applicability of these ingredients is reviewed in terms of nutrient composition, dietary inclusion level, performance output, digestibility, and health benefits. In addition, a meta-analysis was conducted based on data from peer-reviewed scientific publications in order to assess whether novel ingredients meet the dietary protein (amino acid) and lipid requirements of finfishes. Aquafeed reformulation strategies should ensure the recommended daily nutritional requirements and additionally indicate the meta-analysis alternatives, such as microalgae, which are deficient in essential amino acids. The sustainable expansion of aquaculture is on the horizon, but which novel ingredients may be regarded as the key drivers to its establishment?
鱼粉和鱼油的大量生产急剧加剧了远洋渔业过度开发的严重状况。后者与对低成本、富含蛋白质的食物供应日益增长的需求相结合,促使水产养殖业采用新的做法。目前正在对几种新型膳食成分进行评估,以便将其纳入水产饲料,努力使水产养殖业转向更具可持续性和经济性的生产。本综述旨在总结有关鱼粉和鱼油替代品对欧洲水产养殖中最有价值和商业化生产的海洋鱼类(Sarus aurata 和 Dicentrarchus labrax)和淡水鱼类(Salmo salar 和 Oncorhynchus mykiss)的影响的现有研究结果。讨论了替代蛋白质来源,包括大型饲料(海洋植物)、磷虾(海洋渔业)、昆虫(陆生)、陆生动物副产品(加工/屠宰)和单细胞成分(生物技术),以了解它们在促进鱼苗和成鱼养殖中的生长和福利方面的效率。从营养成分、日粮添加量、性能产出、消化率和健康益处等方面审查了这些配料的适用性。此外,还根据同行评审科学出版物中的数据进行了荟萃分析,以评估新型配料是否符合鱼类对日粮蛋白质(氨基酸)和脂质的要求。水产饲料重新配制战略应确保推荐的每日营养需求,并在荟萃分析中指出缺乏必需氨基酸的替代品,如微藻类。水产养殖业的可持续发展指日可待,但哪些新型配料可被视为其发展的关键驱动力?
