Special Issue Information

Dear Colleagues,

The "Selection of Deep-Sea Aquaculture Species and Development of Supporting Technologies and Equipment" aims to explore the identification of viable deep-sea species and the technological advancements required to support their sustainable cultivation. The scope includes species selection criteria, innovations in aquaculture systems, and the development of specialized equipment tailored to the harsh deep-sea environment. Historically, aquaculture has been limited to shallow waters, but recent advancements have shifted focus to deeper, more challenging habitats, driven by the need for resource diversification and environmental sustainability. Cutting-edge research focuses on enhancing species adaptability, improving biosecurity, developing autonomous systems for monitoring and feeding, and optimizing environmental control systems for deep-sea conditions. We are particularly interested in papers that present novel approaches to species selection, technological breakthroughs in aquaculture infrastructure, and strategies for overcoming the unique challenges posed by deep-sea environments, with a focus on sustainability and efficiency.

Bivalves use byssal threads for attachment and locomotion, periodically shedding and regenerating them. In the winged pearl oyster Pteria penguin—known for its strong byssus and its role in the pearl industry—shedding may occur when the byssal stalk reaches a critical size, although the underlying mechanism remains unclear. This study investigated whether artificial manipulation of the byssus (via trimming) could stimulate thread production and promote shedding in adult P. penguin from two size groups. Byssal threads attached to the substrate were trimmed every 3–5 days over a 30-day period and compared to untrimmed controls. Oysters with trimmed byssus produced significantly more threads, with smaller individuals outperforming larger ones in both thread count and byssal stalk diameter. Moreover, small oysters exhibited a higher frequency of complete byssal shedding. These findings suggest that trimming stimulates thread production and accelerates stalk thickening, potentially triggering shedding due to spatial constraints at the attachment site. This response appears to reflect an adaptive mechanism for maintaining effective attachment and may help explain how mechanical or environmental cues influence byssal dynamics. Understanding this process offers new insight into the behavioral and physiological plasticity of P. penguin, with potential applications in pearl oyster management and aquaculture. Full article

Penaeus semisulcatus, a commercially valuable aquaculture species, is widely distributed along the southeastern coast of China and throughout the South China Sea. Despite its economic importance, the comprehensive understanding of its germplasm characteristics remains limited. This investigation evaluated nutrient profiles, amino acid composition, lipid constituents, antioxidant capacity, and genomic variability across three farmed aquaculture populations maintained under standardized environmental parameters to discern divergence in nutritive attributes and hereditary characteristics. The results revealed significant interpopulation variation in ash content (p < 0.05), while other proximate components showed comparable levels. Among 17 detected amino acids, glutamic acid was the most abundant (2.07–2.30 g/100 g), while cysteine had the lowest concentration (0.10–0.11 g/100 g). Notably, the PsHK population had a relatively higher amino acid content, indicating superior nutritional value. Fatty acid analysis detected 13 fatty acids, with C18:0 (88.27–108.00 mg/100 g) being the most abundant, and C20:2 (3.40–4.70 mg/100 g) the least. The PsHK population exhibited significantly higher levels of all fatty acids compared to the other two populations (p < 0.05). Antioxidant enzyme activity assays revealed no significant differences in antioxidant capacity across the three populations, indicating a similar overall antioxidant status. Genetic diversity analysis indicated that the PsHK population had the highest genetic diversity, with a relatively pronounced genetic differentiation between the PsHK and PsRP populations. In conclusion, the comparative analysis of these three cultured populations highlights that the PsHK population excels in both nutritional composition and genetic diversity. With its superior nutritional profile and rich genetic background, P. semisulcatus shows great potential for aquaculture development. These findings provide valuable insights for future germplasm improvement and aquaculture optimization efforts, offering a scientific basis for refining breeding strategies and enhancing the nutritional evaluation of P. semisulcatus. Additionally, the comparative analysis of genetic diversity and biochemical composition contributes to a better understanding of population variation, which is essential for the sustainable management and utilization of this species in aquaculture.

In cryopreservation technology, the choice of cryoprotectant plays a crucial role in cell survival and function. Different types of cryoprotectants, each with unique protective mechanisms, mitigate cellular damage from ice crystal formation during freezing. This study investigated the effects of different types and concentrations of cryoprotectants on the cryopreservation efficacy of noble scallop Mimachlamys nobilis sperm. Six cryoprotectants were tested, including four permeable cryoprotectants (dimethyl sulfoxide (DMSO), ethylene glycerol (EG), propylene glycerol (PG), methanol (MET)) and two non-permeable cryoprotectants (trehalose (TRE), fetal bovine serum (FBS)). The results showed that permeable cryoprotectants, which penetrate the cell membrane, regulate the osmotic pressure inside and outside cells to reduce dehydration damage. Among them, 10% DMSO provided the best protection, significantly preserving sperm motility, velocity, and morphology. Non-permeable cryoprotectants, although unable to penetrate cells, stabilized the extracellular environment at higher concentrations (such as FBS). Additionally, MET and FBS exhibited enhanced protective effects with increasing concentration, indicating their potential in reducing sperm structural damage at higher concentrations. Morphological observations indicated that freezing caused varying degrees of structural damage to sperm, with flagellar integrity being crucial for motility. Overall, selecting an appropriate cryoprotectant and concentration is essential for the efficient cryopreservation of M. nobilis sperm, providing a valuable reference for conserving germplasm resources of marine species.

Environmental temperature declines significantly impact the physiological processes of marine organisms, particularly under the cool La Nina conditions, challenging yellowfin tuna (Thunnus albacares) aquaculture. Low temperatures affect fish metabolism and immune functions and can alter the gut microbiota composition, influencing health and growth. This study investigates the impact of low temperatures on the gut microbiota of juvenile yellowfin tuna. Fish were divided into a Low Temperature (LT) group (24 °C), an Ultra Low Temperature (ULT) group (18 °C), and a Control group (CG) (30 °C), with evaluations at 0, 12, 24, and 36 h using α-diversity analysis and microbial species composition. Results indicated a significant increase in the Ace index for the ULT group after 36 h of cold stress (p < 0.05), with no significant changes in the Shannon index. A decline in Proteobacteria and increases in Verrucomicrobiota and Firmicutes were observed in both LT and ULT groups. Additionally, both LT and ULT groups showed a significant rise in the Ace index at 36 h (p < 0.05), with a significant decrease in the Shannon index in the ULT group at 24 h. Furthermore, Firmicutes significantly increased at 12 h in both temperature groups (p < 0.05). These findings highlight the potential role of the gut microbiome in adapting yellowfin tuna to cold environments and provide microbial insights into their physiological adaptations, laying a foundation for further research and practical applications in aquaculture under cold conditions.
