“…Studies showed that botanical polysaccharides can enhance the innate immunity and resistance to pathogens of aquatic animals (Huang et al 2006;Cheng et al 2007;Yeh et al 2008;Wang et al 2009). The present results clearly indicate that dietary ASP boosts the cellular immunity of E. malabaricus, when assayed by respiratory burst activity, phagocytic activity, and leukocytes proliferation.…”

The purpose of this study was to determine the effect of Angelica sinensis polysaccharide (ASP) supplemented in diet on the innate cellular immune response and disease resistance in grouper, Epinephelus malabaricus. Fish were fed diets containing different doses of ASP (0, 500 and 3,000 mg kg -1 diet) for 12 weeks. After 12 week feeding, the respiratory burst activity, phagocytic activity, and leukocytes proliferation in head kidney were assayed. The functional immunity in terms of cumulative mortality was also assessed by a challenge with live Edwardsiella tarda. Results showed that the respiratory burst activities in ASP-supplemented groups were increased significantly. The respiratory burst index was the highest in fish-fed 3000 mg kg -1 diet and the lowest in control. The phagocytic activities in ASP-supplemented groups were significantly higher than that of control. No significant difference in phagocytic activity was observed between ASP-supplemented groups. ASP stimulated the head kidney leukocytes proliferation significantly, despite the absence of lipopolysaccharide (LPS) or not. The cumulative mortalities of fish fed with 3000 mg ASP kg -1 diet were significantly lower than those fed with 500 mg ASP kg -1 diet and control diet after 96 h of challenge. In conclusion, dietary ASP enhanced some cellular immune parameters and disease resistance against E. tarda in grouper.

“…Their similar biochemical composition to that of pullulan, as well as their effect on the production of NO and IL-6 by RAW macrophages, suggests that the polysaccharides from H. incurva might also induce cellular immune response. Polysaccharides from a number of seaweed (Schepetkin and Quinn 2006;Castro et al 2006) and higher plants (Pereira et al 2000;Cheng et al 2007) have been reported to enhance phagocytic and secretory activity of macrophages and phagocytes. The polysaccharides from Porphyra yezoensis, for example, induced the in vitro and in vivo production of NO and TNF-α by murine macrophages (Yoshizawa et al 1993).…”

Red algae have been reported to be an important source of polysaccharides with potential immunomodulatory properties. The objective of this study was to characterize the polysaccharides from Halopithys incurva and Hypnea spinella and to evaluate their effect on the synthesis of cytokines by murine cell line RAW 264.7 macrophages. Polysaccharides were obtained by N-cetylpyridinium bromide precipitation and characterized by Fourier transform-infrared spectroscopy. Their effect on the activity of RAW 264.7 macrophages was examined by quantification of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and nitric oxide (NO) production using enzyme-linked immunosorbent assays. The activation of the cytokine IL-6 and NO increased linearly as the concentration of polysaccharides from H. incurva and Hy. spinella increased. In general, the activation of IL-6 and NO was tenfold greater when macrophages were exposed to polysaccharides from H. incurva than when exposed to polysaccharides from Hy. spinella. In contrast, TNF-α concentration did not increase when macrophages were exposed to increasing polysaccharide levels. These results indicate that polysaccharides are strong cytokine IL-6 inducers.

“…Growing concerns about the use of antibiotics in aquaculture has directed attention towards natural compounds with potent antimicrobial and immunostimmulating properties such as various plant-derived compounds (Citarasu, 2010). The beneficial effects of algae-derived bioactive compounds on fish immune function and consequently on their resistance to certain pathogens has been demonstrated in several studies on various fresh water and marine fish species including carp (Cyprinus carpio) , turbot (Scophthalmus maximus L.) (Skjermo et al, 1995), rainbow trout (Oncorhynchus mykiss) (Peddie et al, 2002), Atlantic salmon (Salmo salar L.) (Dalmo and Seljelid, 1995) and grouper (Epinephelus coioides) (Cheng et al, 2007;Yeh et al, 2008). Chiu et al (2008) found that supplementation of sodium alginate, a natural polysaccharide derived from brown algae, to juvenile grouper (Epinephelus fuscoguttatus) diets can significantly enhance innate immune response and disease resistance against Streptococcus sp.…”

A 6-week feeding trial was conducted to evaluate the efficiency of hijiki (Sargassum fusiforme) and ecklonia (Ecklonia cava) as dietary supplements for juvenile olive flounder. Fish growth performance, hematology, innate immunity and disease resistance were examined. A basal experimental diet was used as a control and supplemented with 6% of either S. fusiforme or E. cava and another diet was prepared to contain 0.5% oxytetracycline (designated as Con, Hij-6, Eck-6 and OTC-0.5, respectively). The experiment was conducted in triplicate (25 fish per replicate) and the fish (initial body weight, 18.3±0.04 g) were fed one of the test diets at a rate of 3% body weight twice daily. Significantly higher (P<0.05) antioxidant capacity and polyphenolic compounds concentration were detected in hijiki and ecklonia supplemented diets. At the end of the feeding trial, fish growth performance and feed utilization were not significantly affected by dietary treatments. Significantly higher (P<0.05) hemoglobin level and respiratory burst activity were found in fish fed Hij-6 diet. The fish fed Hij-6 and Eck-6 diets exhibited higher resistance against Edwardsiella tarda challenge compared to those fed Con and OTC-0.5 diets. The findings in this study may show that hijiki and ecklonia can be used as environment friendly substitutes for antibiotics in diets for olive flounder.
