Global warming, as a key driver of climate change, is accelerating water temperature rise, with significant implications for aquatic ecosystems. Temperature, a critical abiotic factor, directly affects the physiology, growth, and survival of aquatic organisms. In the context of aquaculture—one of the fastest-growing food sectors—crustaceans hold high commercial value due to their production volume and global demand. However, their sensitivity to thermal fluctuations poses major challenge under climate change. This review examines the impact of elevated temperatures on growth performance, food intake, moulting, immune response, and survival of major farmed crustaceans, including shrimp, prawns, crabs, lobsters, and crayfish. Broader ecological consequences, such as disruptions in nutrient cycling and disease outbreaks, are also explored. Additionally, we evaluate mitigation strategies, including dietary modification, technological innovations, biotechnological approaches, and aquaculture insurance models. By integrating physiological, immunological, and ecological evidence, this review identifies key knowledge gaps and highlighting opportunities to improve climate resilience in crustacean aquaculture. Understanding these challenges is essential for sustaining productivity and promoting adaptive management in a warming world.

Innate immunity in fish is critically important for preventing the entry of pathogenic microorganisms by adeptly recognizing pathogen-associated molecular patterns (PAMPs) through pattern recognition receptors (PRRs). Concurrently, the adaptive immune response equips the vertebrate immune system to identify and retain memory of specific pathogens, thereby facilitating enhanced secondary responses upon re-exposure. Antigen-presenting cells (APCs) are integral to this process, as they recognize antigens via mechanisms including PRRs, internalize them, and process these antigens for presentation to T cells. This interaction triggers the activation of both T cells and B cells, initiating a robust priming of the adaptive immune system and establishing a functional bridge between innate and adaptive immunity. Antigen presentation serves as a pivotal mechanism for T cell activation and B cell differentiation, thereby leading to the establishment of effective antimicrobial protection. Vaccination of fish is of paramount importance for preventing specific infectious diseases and is economically and environmentally essential for the development of a sustainable fish aquaculture industry. The design of efficacious vaccines necessitates the establishment of long-term protection against specific antigenic challenges, with APCs occupying a central role in this endeavor. This review summarizes the most recent studies on fish antigen presentation pathways and elucidates the mechanisms involved in the recognition, processing, and presentation of antigens by APCs, triggering activation of T cells. Moreover, this review highlights recent findings concerning immune regulatory factors that activate adaptive immunity, including adjuvants and immunostimulants, providing the prospects for fish vaccine applications. A comprehensive understanding of how fish APCs detect and respond to antigens will have profound implications for the future development of tailored vaccination strategies and the rational design of interventions against infectious diseases impacting the commercial aquaculture sector.

This study aimed to evaluate the Lithothamnium organic mineral in the diets of Penaeus vannamei in low-salinity water with a synbiotic system. Two diets were formulated by partially replacing inorganic minerals (calcium, magnesium, and potassium) with a commercial source of Lithothamnium at levels of 2% (LT2) and 4% (LT4) per kg of diet, and two more diets were prepared using the same levels: 2% (CTLT2) and 4% (CTLT4) of Lithothamnium per kg of diet, fixed onto the pellets using a commercial binder. The experiment was conducted for 50 days with a stocking density of 50 shrimps (3.1 g) per m2 in a low-water salinity synbiotic system. Different doses and application forms affected the activities of digestive enzymes (trypsin, chymotrypsin, leucine aminopeptidase, amylase, and lipase) in the shrimp hepatopancreas. The oxidative stress enzymes did not differ significantly between the times analyzed, but MDA at 25 days of culture showed different values between LT2 and LT4 treatments compared to CTLT4. The shrimp's proximate and mineral composition showed that the concentration of lipids was lower in the CTLT2 and CTLT4 treatments, while the concentration of calcium was higher in the CTLT4 treatment. The LT2 treatment has a significant difference in shrimp performance (final weight, weekly growth, yield, and FCR) and a higher return on investment (34.26) compared to the other treatments and the control. Based on these results, the Lithothamnium organic mineral addition in diets for Penaeus vannamei for optimal growth was 2% addition (LT2) in the shrimp feed.

As the production of fish and shellfish is increasing, and the price of fishmeal is high cheaper suitable alternatives must be evaluated. Spirulina (Arthrospira), a filamentous blue-green microalgae, reported worldwide in fresh and marine waters, could be an alternative protein- and vitamins source. According to the Web of Science using the key words Spirulina and aquaculture 640 studies have been published on the topic since the first study was published by Stanley and Jones in 1976. Some microalgae including Spirulina contain several bioactive phytochemicals that exhibit anti-inflammatory, antioxidant, and immunomodulatory properties. Based on this, numerous studies have revealed that the supplementation of Spirulina to several fish and shellfish species improve growth performance, enhance cellular and humoral immunities, modulate the gut microbiota composition and improve disease resistance towards pathogenic infection (Vibrio alginolyticus, Vibrio harveyi, Aeromonas hydrophila and Aeromonas sobria). This review article evaluates the supplementation of Spirulina as a functional feed additive in sustainable fish and shellfish aquaculture.
随着鱼类和贝类产量的增加，以及鱼粉价格的上涨，必须评估更便宜的合适替代品。螺旋藻（节肢螺旋藻）是一种丝状蓝绿色微藻，在淡水和海水中都有报道，可以作为蛋白质和维生素的替代来源。根据Web of Science使用的关键词螺旋藻和水产养殖，自Stanley和Jones在1976年发表第一项研究以来，已经发表了640项关于该主题的研究。包括螺旋藻在内的一些微藻含有几种具有抗炎、抗氧化和免疫调节特性的生物活性植物化学物质。基于此，大量研究表明，在几种鱼类和贝类中添加螺旋藻可以改善生长性能，增强细胞和体液免疫，调节肠道菌群组成，提高对致病性感染（溶藻弧菌、哈维弧菌、嗜水气单胞菌和温和气单胞菌）的抗病能力。本文综述了螺旋藻作为一种功能性饲料添加剂在鱼贝类可持续养殖中的应用。

Gamma-aminobutyric acid (GABA) regulates several physiological, neuroendocrine, and behavioural functions, yet the specific role of its receptors in the hypothalamic-pituitary-testis (HPT) axis remains unclear in teleosts. We investigated the effects of muscimol (MUSC, a GABAA receptor agonist) and baclofen (BAC, a GABAB receptor agonist) on the HPT axis in the male black molly Poecilia sphenops. Administration of 0.05 μg MUSC on alternate days for 21 days upregulated gonadotropin-releasing hormone-I (GnRH-I) mRNA levels in the preoptic-hypothalamus, whereas they were downregulated in 0.5 or 5 μg MUSC-treated groups. The GnRH-I mRNA levels were unaltered following treatment with 5 or 10 μg BAC, but they were upregulated in 50 μg BAC-treated fish. The luteinizing hormone-β (LH-β) mRNA levels were unaltered following MUSC or BAC treatment across all doses. The numbers of all germ cell types were significantly decreased in 5 μg MUSC-treated fish concomitant with significantly lower levels of testicular 11-ketotestosterone (11-KT). On the other hand, treatment with 50 μg BAC caused a significant increase in the majority of the germ cells and testicular levels of 11-KT compared to controls. Furthermore, in vitro 11-KT levels in the testis were significantly increased in MUSC + human chorionic gonadotropin (hCG)-treated fish compared to those of the MUSC-alone group; however, a similar treatment of BAC + hCG did not attenuate the inhibitory effect of BAC-alone treatment. These findings suggest that GABAA and GABAB receptor agonists produce differential effects on the HPT axis of the black molly. In particular, MUSC suppresses the GnRH-I mRNA expression and spermatogenesis process at higher doses, whereas BAC promotes these processes at high concentration.

Fishing is a significant global food source, providing protein for millions of people. The Food and Agriculture Organization (FAO) is committed to ensuring access to high-quality food, reducing hunger, and promoting sustainable fisheries to address global population growth and hunger. However, illegal, unreported, and unregulated fishing poses a significant challenge, threatening marine biodiversity and food security. Portugal has the 10th largest Exclusive Economic Zone (EEZ), with waters around mainland Portugal, the Azores, and Madeira. This research focuses on the Azores region, known for its traditional multispecific fishery around the island slopes and seamounts. The region's fisheries face data scarcity issues and complicating effective management. By combining Vessel Monitoring System (VMS) records from 2016 to 2022 and Portuguese Navy (PoN) Fiscalization Reports (FISCREP) from 2015 to 2022, it was possible to use appropriate metrics to characterize the fishing effort and analyze the effectiveness of the inspections conducted in the Azores EEZ. The Total Boat-Meter (TBM) metric combines the number and length of boats to quantify the fishing effort better. The analysis shows that the fishing effort in the protected areas is very high, highlighting the pressure on the protected ecosystems. The findings aim to assist regulatory institutions and researchers in assessing fishing pressure and promoting sustainable fisheries management in the Azores to preserve marine ecosystems.

Although the aquaculture industry has undergone monumental development worldwide, the ever-present threats of infectious diseases have become a constraining factor, imperiling its sustainability. Antimicrobial resistance (AMR) remains a real menace to industrial aquaculture due to the careless adoption of preventive therapies (antimicrobial therapeutic drugs) to forestall disease outbreaks in aquatic food production. Suitable strategies, or at least supplementary measures, should therefore be developed to curb the emergence and widespread transmission of AMR. Vaccination represents one of the primary options to substantially mitigate the economic damages imposed by emerging infectious diseases on global aquaculture; nevertheless, the availability of commercial aquatic vaccines is usually limited, and many vaccines only confer minimal or poor protection against infections (during the early stages of animal development). Accordingly, a large body of research has been enthusiastically exploring alternate approaches for managing animal health challenges. These efforts have led to the establishment of various biocontrol strategies, such as the versatile use of high-value functional ingredients (e.g., probiotics, prebiotics, synbiotics, paraprobiotics, postbiotics, and phytogenics), phage therapy, and quorum-sensing interference (QSI), to promote the health and welfare of farmed aquatic species in a responsive or preventative manner. This review article addresses the state-of-the-art pertinent to biological control as an eco-friendly green approach for aquatic disease management, paving the route to a sustainable blue revolution. The potential biological mechanisms of these strategies are also described, along with the impediments to scientific progress and topics that merit further investigation.

To unravel the intricate morphological structure and functional aspects of the digestive system in Procambarus clarkii, this study employed histology and transcriptome sequencing techniques for a comprehensive analysis of its digestive system. The investigation revealed that the digestive system of P. clarkii comprises the esophagus, stomach (including cardiac and pyloric regions), caeca, midgut, hindgut, and hepatopancreas. The esophageal lumen displayed an "X" shape, with clearly visible radial muscle bundles within the connecting tissues. The internal architecture of the stomach and intestines mirrored that of the esophagus. Notably, the pyloric region of the stomach exhibited a comb-like structure, which facilitated food selection and filtration. The caeca showcased a larger lumen within the intestines, while the hindgut displayed smaller folds. The hepatopancreas, representing the digestive glands, demonstrated predominant bilaterally symmetrical features, encompassing the midgut on both sides. It consisted of multi-stage branching hepatic ducts, crucial for digestion and absorption. Transcriptomic analysis of the digestive system revealed significant gene expression in the esophagus, stomach, caeca, midgut, hindgut, and hepatopancreas, with 23,006, 22,208, 23,485, 23,196, 22,781, and 21,375 genes expressed, respectively. Moreover, tissue-specific expression was observed in 161, 459, 374, 547, 337, and 1080 genes. Additionally, a subset of 447, 453, 553, 506, 433, and 711 genes exhibited high expression levels. Further analysis led to the identification of 36 digestive enzyme genes across six distinct digestive tissues, categorized into three groups: carbohydrate metabolism, lipid breakdown, and protein metabolism. In conclusion, this study provides a comprehensive understanding of the morphological structure, gene expression characteristics, and classification of digestive enzyme genes in the digestive system of P. clarkii. These findings lay a solid foundation for future investigations on the digestive physiology and food digestion in P. clarkii.
