“…In this study, alternative complement pathway activity was enhanced significantly in fish fed UL-25 at all sampling times analysed. Our results differ from Fumanal et al (2020), who found that dietary administration of 5% U. ohnoi during 90 days did not modify neither systemic immune response nor complement activity. Those authors suggest that changes in immune response and complement activity might polysaccharides activated the immune system (del Rocío Quezada-Rodríguez & Fajer-Ávila, 2017;Tabarsa et al, 2018), including the complement activity (Ponce et al, 2020;Safavi et al, 2019).…”

“…piscicida challenge were not affected in Senegalese sole receiving 5% U. ohnoi diet although increased transcription of genes encoding complement, and lower pathogen loads were detected in the liver (Fumanal et al, 2020). In the present study, results evidenced lower protection than that obtained with some of the existing vaccines against P. damselae subsp.…”

“…The use of immunostimulants to enhance the non-specific immunity and to prevent the bacterial diseases has been evaluated (Yengkhom et al, 2018). In this context, immunomodulatory activity has been previously described after dietary administration of algae to farmed fish (Fumanal et al, 2020;García-Márquez et al, 2020;Valente et al, 2016).…”

Given the potential of algae as a new aquafeed ingredient, this study evaluated the effect of the tank-cultivated macroalgae Ulva rigida C. Agardh (Chlorophyta) on innate immune response, intestinal microbiota and their resistance against Photobacterium damselae subsp. piscicida in juvenile gilthead seabream (Sparus aurata L.) after a short pulse of administration. An algae-free diet was used as control, and an experimental diet was formulated containing 25% of U. rigida (UL-25). After 2, 7, 15 and 30 days biological samples were taken. No statistical significance (p > 0.05) was detected in respiratory burst activity. Diet UL-25 significantly enhanced alternative complement pathway activity respect to control diet from the beginning of the experiment (p < 0.05). When fish were challenged against P. damselae subsp. piscicida, UL-25-fed fish were more resistant against the pathogen than the fish fed control diet, obtaining a relative survival percentage of 54.55%. The ability of UL-25 diet to modify the intestinal microbiota was also confirmed. In conclusion, the use of a short pulse of dietary administration of 25% U. rigida in S. aurata diet modulates the immune response, intestinal microbiota and reduced the mortality rate during P. damselae subsp. piscicida infection.

Considering algae as novel dietary ingredient for aquafeeds, this study evaluates the effects of three algae, Ulva rigida, Crassiphycus corneus (formerly Hydropuntia cornea) and Scenedesmus almeriensis, on non-specific immune response and fatty acid profile in juvenile Nile tilapia (Oreochromis niloticus) after a short dietary administration period (30 days). U. rigida, C. corneus and S. almeriensis diets (UL-25, CC-25 and SC-25 respectively) included 25% dry algae biomass, whereas an algae-free diet was used as control. Biological samples were taken at 7, 15 and 30 days. Diet SC-25 significantly improved respiratory burst, alternative complement (ACH50) and lysozyme activity (p < .05). Regarding tissue fatty acid composition, SC-25 diet reduced the levels of saturated fatty acid in liver and muscle, while increased levels of C20:3n6 and eicosapentaenoic acid (EPA) in liver, and total n-3 content, arachidonic acid (ARA), EPA and docosahexaenoic acid (DHA) in muscle (p < .05). UL-25 and CC-25 groups showed the lowest levels of ARA in liver but increased levels of monounsaturated fatty acids. In conclusion, the results obtained lead us to consider the use of a short pulse of dietary algae is suited for improving the immune response and modulating the tissue fatty acid composition in this fish species.

“…The DPPH assay is the fastest method to measure antioxidant ability, compared to other methods that are also commonly used, namely reducing power and superoxide anion radical scavenging activity [76,102,107,108,110,111]. Notably, using more than one method to assess antioxidant activities increases the accuracy of the results.…”

The species of green macroalga belonging to the genus Ulva (family: Ulvaceae) are utilized in various fields, from food supplements to biomedical applications. Ulvan, a polysaccharide obtained from various Ulva species, has shown various biological activities, including antioxidant, anti-inflammatory, anticancer, antibacterial, and antiviral activities. To obtain the polysaccharide ulvan that can be utilized in various fields, it is necessary to understand the critical points that affect its physicochemical nature, the extraction procedures, and the mechanism of action for biological activities. This article discusses the physicochemical properties, extraction, isolation and characterization procedures and benefits in food and biomedical applications of ulvan. In conclusion, ulvan from Ulva sp. has the potential to be used as a therapeutic agent and also as an additional ingredient in the development of tissue engineering procedures.
