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.

“…Previous studies have confirmed the growth index parameters such as the weight gain rate (WG) (Doan et al, 2017), final length (FL) and length increase (LG) (Hua et al, 2005), specific growth rate (SGR) (Yin et al, 2014) and feed conversion rate (FCR) (Faghani et al, 2008) of laminarin for fish have a significant impact. On the other hand, oral laminarin and others nutrition caused a significant increase in WG and SGR in Epinephelus coioides and Mugil cephalus (Akbary & Aminikhoei, 2017; Yin et al, 2014). In this study, from the growth results, the main effects are at the added doses of laminarin at 4 g and 8 g, and these two places show different growth promotion status.…”

In this study, the different dosage of laminarin groups (normal fodder group (Control), normal fodder add 1 g laminarin group (AL1), normal fodder add 2 g laminarin group (AL2), normal fodder add 4 g laminarin group (AL4) and normal fodder add 8 g laminarin group (AL8)) were set. After 45 days, the growth, enzyme activity and immune‐related gene were measured to assess the effect of feeding laminarin on Ictalurus punctatus. Laminarin (4 g dosage) can significantly increase body length (p < .05) and BMI (body mass index) value in 8 g dosage group (p < .05). Lysozyme, acid phosphatase, aspartate aminotransferase, catalase, superoxide dismutase, pepsin, amylase and trypsin activity are increased with the dosage of laminarin increasing, and have a significant difference at the dosage of 4 g and 8 g group (p < .001). However, the serum cortisol content, alkaline phosphatase and lipase activity have a significant inhibition in high‐dosage groups (p < .001). The expression of TLR5 gene in group of 4 g dosage was significantly upregulated (p < .05). The expression of SOCs gene in groups of 2 g (p < .05), 4 g (p < .001) and 8 g (p < .001) dosage was significantly downregulated. The expression of IGF2 and STAT5 genes was significantly upregulated in high‐dosage laminarin groups. Generally, larminarin enhances the immune response, reduces the rate of energy decomposition required and improves food absorption. This shows that the larminarin improves the physical quality and increases productivity of I. punctatus, and offers great potential for application in the aquaculture industry.

“…It is suggested, the reason why a concentration of 100 mg kg −1 UFME better than 150 mg kg −1 UFME is the phytol component which have anti-metabolic-syndrome properties and anti-inflammatory at physiological concentrations (Bobe et al, 2020). Similar results were reported by Akbary and Aminikhoei (2017). Therefore, the use of immunostimulants has been widely advocated to control diseases in farmed aquatic animals.…”

“…Ulva secondary metabolites showed great activity in antibacterial, ichthyotoxicity, larvicidal and antifouling assays (Selvin &Lipton, 2004 andAkbary &Aminikhoei, 2018). Ulva fasciata is a marine macro algae, green in colour (Phylum: cholorophyta, Class: chlorophyceae), and grows plentifully in both surface and deep water layers of sea (Sivakumar et al, 2014).…”

Worldwide fish production continues to go beyond world population growth and fish farming remains the field that grows faster than many other fields (Moffitt & Cajas-Cano, 2014). After 40 years of constant growth in fish farming-related production, over half of the fish used globally is supplied by this sector and most of the aquatic products create an important food source with increasing economic importance (Moffitt & Cajas-Cano, 2014). Diseases of water living organisms like fish are the most restriction to the progress of the worldwide fish farming related manufacturing and commerce. Moreover, malnutrition and environmental stressors may affect fish growth and ability to defend against infections (Meena et al., 2013). Antimicrobial agents such as oxytetracycline, amoxicillin, etc. have been broadly used to eliminate infections related to various microbes such as Aeromonas hydrophila (Depaola et al., 1995). Excessive usage of antimicrobial agents in fish farms provides a selective pressure generating drug-resistant bacteria in addition, transportable resistance genes in fish microbes (Heuer et al., 2009). Resistance genes may possibly broadcast by horizontal gene transmission and become human pathogens or drug-resistant pathogens and the occurrence of resistance to these antimicrobial
