Special Issue Information

Dear Colleagues,

Aquatic animal health is a critical pillar of global food security, sustainable aquaculture, and ecosystem stability. This Special Issue invites contributions on cutting-edge research aimed at combating diseases in aquatic species. The rapid expansion of aquaculture to meet the rising protein demand has promoted the emergence of pathogens and environmental stressors that pose significant threats to productivity and biodiversity. We seek high-quality original research and reviews, including innovative diagnostic technologies, surveillance systems, novel vaccine development, immunostimulants, and biosecurity strategies. Emphasis will be placed on genomic and molecular tools for pathogen detection, novel prevention and control measures, and sustainable management practices. Studies exploring host–pathogen interactions, disease-resistant genes identification, the mechanism of host immune defense, and pathogen immune escape are also particularly welcome. By compiling advancements in this field, this Special Issue aims to foster interdisciplinary collaboration and translate scientific discovery into practical solutions, ultimately supporting the healthy and high-quality development of the aquaculture industry.

Plant extracts contain multiple bioactive compounds and have been extensively investigated as alternatives to antibiotic-based feed additives in aquaculture. The present study was designed to evaluate the effects of dietary supplementation with galangal (Alpinia officinarum) extract (AO) on the growth, immune response, intestinal digestive enzyme activities, gut microbiota, and resistance to A. hydrophila in red claw crayfish (Cherax quadricarinatus). Crayfish with an initial body weight of 0.83 ± 0.05 g were randomly assigned to 18 tanks (6 groups × 3 replicates) and were fed basal diets supplemented with 0, 0.5, 1, 3, 5, or 7 g/kg of AO for 8 weeks. The weight gain rate (WGR) and specific growth rate (SGR) of crayfish were significantly higher in the 3 g/kg and 5 g/kg groups than in the control group. Dietary supplementation with 3–5 g/kg AO significantly elevated the crude protein content and reduced the crude lipid content in the muscle. AO supplementation at 3–5 g/kg significantly enhanced the total antioxidant capacity (T-AOC) and the activities of glutathione peroxidase (GPx), catalase (CAT), acid phosphatase (ACP), and phenol oxidase (PO), whereas the content of malondialdehyde (MDA) was significantly reduced. Dietary AO supplementation markedly increased the relative abundance of Firmicutes, Cytophaga, and norank_o_Saccharimonadales. Moreover, dietary AO significantly upregulated the expression of multiple functional genes in the hepatopancreas, including ecCu, Zn-SOD, Trx1, ALF, C-LZM, GPx, and Se-GPx, and improved the survival of the C. quadricarinatus under challenge with A. hydrophila. Collectively, the findings of the present study indicate that dietary supplementation with 3–5 g/kg AO enhances the growth performance, intestinal digestive enzyme activities, immune function, and disease resistance in the red claw crayfish (C. quadricarinatus).
