Replacement of dietary kelp meal with three macroalgae sources on the growth performance, immune responses and anti-stress capacity of abalone Haliotis discus hannai

Three Types of Enteromorpha prolifera Bio-Products Based on Different Processing Procedures as Feed Additives in the Diets of Pacific White Shrimp (Litopenaeus vannamei)

“…These biological activities of E. prolifera polysaccharide were not only confirmed in terrestrial animals [5,9], but also in fish and shrimp [2,10]. In addition, some studies found that seaweed polysaccharide could mitigate various stress responses, such as air exposure, heat stress and ammonia stress [11][12][13][14]. Except for the polysaccharide, E. prolifera had been shown to enhance feed intake of fish due to its potential feeding attractants, such as betaine [2,15].…”

“…Apart from the lipid metabolism, antioxidant, and immune effects, the stress resistance of E. prolifera bio-products was evaluated in this study. Polysaccharides from seaweed could improve survival rate of aquatic animals under various stress, such as air exposure, ammonia stress and heat stress [12][13][14]. Survival rate was used as an important index for comprehensive evaluation of resistance to stress because its challenge tests reflected nonspecific immune and anti-oxidation functions of the organisms [39].…”

Dietary replacement of Undaria pinnatifida by Sargassum horneri in feed formulation for abalone Haliotis discus hannai: Effect on growth, gut microbiota, and taste sensory profile

“…However, these species are bounded with several problems including availability as only exclusively harvestable during the winter season (Lee et al, 2016), increasing market price (Jang et al, 2018), and unsustainable in the long run as also being farmed for biopharmaceutical application and human consumption (Hwang and Park, 2020). It is further known from previous studies that over a single macroalga, a combined macroalgae in the diets offers well-balanced nutrition and improves immunity and subsequently faster growth performance in a range of abalone species (Dang et al, 2011;Viera et al, 2011;O'Mahoney et al, 2014;Ansary et al, 2019b;Sun et al, 2021). As a result, earlier studies affirmed the necessity of using additional seaweed species as a source of macroalgal biomass for abalone aquaculture (Mulvaney et al, 2013;Jang et al, 2018;Ansary et al, 2019a).…”
