Summary: The study found that regardless of the administration period (15 to 45 days), β-glucan enhanced innate immune responses and disease resistance in Nile tilapia, with the protective effect lasting up to 10 days post-feeding trial. Additionally, longer administration did not lead to immunosuppression as previously thought, but rather promoted growth and immune performance.

Summary: This experiment demonstrated that Astragalus polysaccharides (APS) had immunomodulatory effects on crucian carp, enhancing immune-related indicators and antiviral abilities. The results showed that APS could significantly improve the immune response and resistance against viral infection in crucian carp and EPC cells infected with SVCV.

Summary: This study demonstrates that dietary silkrose-AY from the Japanese oak silkmoth can enhance the survival of medaka fish infected with Edwardsiella tarda, while decreasing bacterial load in their kidneys. Microarray analysis revealed differential expression of 2930 genes in the intestine of fish fed with silkrose-AY, highlighting the involvement of various genes related to pathogen recognition, complement cascade, antimicrobial peptides/enzymes, opsonization/phagocytosis, and epithelial junctional modification in the immune response to bacterial infection.

Summary: In this study, the potential immunostimulatory effects of mangosteen peel extract on Macrobrachium rosenbergii were investigated. The results showed that the administration of mangosteen peel extract significantly increased total haemocyte count, differential haemocyte count, phenoloxidase activity, respiratory bursts, as well as phagocytic activity and clearance efficiency against Lactococcus garvieae. These findings suggest that mangosteen peel extract can be utilized as an immunostimulant for prawns through dietary administration, enhancing immune responses and resistance against pathogens by modulating carbohydrate metabolism.

Summary: This study investigated the effects of feeding diets containing tyramine to Litopenaeus vannamei on growth performance, immune parameters, metabolic processes, and resistance against Vibrio alginolyticus. The results showed that feeding shrimp with tyramine-containing diets improved feed efficiency, weight gain, immune activity, and resistance against bacterial infection.

Summary: This study investigated the effects of different levels of dietary chromium on multiple aspects of abalone. The results showed that moderate levels of chromium had positive effects, while high levels decreased flesh quality and excessive levels had negative effects on the health of abalone.

Summary: The study demonstrates that feeding shrimp with diets containing CPH pectin significantly improves growth rate, feeding efficiency, and disease resistance. Within a certain dosage and time frame (3.0 g/kg and 56 days), CPH pectin acts as a regulator for shrimp neuroendocrine and immune responses, as well as carbohydrate metabolism, enhancing resistance against pathogens and hypothermal stress.

Summary: l3-glucans are linear polysaccharides composed of D-glucose monomers linked through l3-glycosidic bonds, which are widely present in nature. They have been recognized as safe and functional components with biological activities including lipid-lowering, hypoglycemic, antitumor, and immune regulation. Soluble l3-glucans can bind to immune cell receptors, activate pro-inflammatory responses, and enhance the host's antitumor defense.

Summary: In this study, multilayered alginate/chitosan microparticles were fabricated to enhance the oral administration of large cranberry fruit extracts. The size and properties of the microparticles were influenced by the outermost layer composition. The microparticles showed good drug entrapment efficiency and release profiles.

Summary: This study investigated the effects of flaxseed oil as a feed additive on the growth, oxidative stress, immunity, and disease resistance of rainbow trout. The results showed that the addition of flaxseed oil increased the final weight and specific growth rate of the fish, as well as their resistance to a specific bacteria. Furthermore, flaxseed oil improved the immune response and reduced oxidative damage in the fish.

Summary: Yeast cells and their cell wall components, especially beta-glucans, have strong immunostimulatory effects on bivalves. However, it is unclear whether long-term use of yeast contributes to prolonged immune activity in bivalves. Understanding these innate immune mechanisms is important for developing feeding strategies and disease prevention in hatcheries and nurseries. This study investigated the immunostimulatory effect of continuous dietary supply of a yeast mutant on Crassostrea gigas juveniles and its protective effect against Vibrio coralliilyticus infections.
