Suitability of Novel Algal Biomass as Fish Feed: Accumulation and Distribution of Omega-3 Long-Chain Polyunsaturated Fatty Acid in Zebrafish

Role of dietary Schizochytrium sp. in improving disease resistance of zebrafish through metabolic and microbial analysis

“…is rich in omega-3 LC-PUFAs, especially DHA, and a recent study recorded a signi cant increase in the fatty acid content in zebra sh fed Schizochytrium sp. diets [8]. Therefore, the reduced abundance of Bacteroidetes in zebra sh fed with 120 g/kg Schizochytrium sp.…”

“…In recent decades, different microalgae species have been tested for use in aquaculture applications [8,9]. Microalgae contain many bioactive components, such as omega-3 fatty acids, β-glucans, and avonoids.…”

“…Compared with landbased crops, microalgae have a nutritional quality that is more similar to sh oil, especially in terms of proteins, lipids, vitamins, and minerals, and, hence, they are considered as a promising alternative to sh oil and could enhance sustainability in aquaculture [6]. Studies have shown that marine microalgae diets that are rich in long-chain polyunsaturated fatty acids (LC-PUFA), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), can improve the growth, nutritional performance, and fatty acid pro le of sh [3,7,8]. Moreover, Sheikhzadeh et al have found that dietary supplementation with 2.5% Spirulina platensis could improve mucosal immune responses and disease resistance in rainbow trout [9].…”

“…To our knowledge, many researchers have focused on improving growth and the ratio of LC-PUFA with dietary containing with Schizochytrium sp. both in juvenile and adult sh, such as the Atlantic salmon (Salmo salar) [12,13], Paci c white shrimp (Litopenaeus vannamei) [14], channel cat sh (Ictalurus punctatus) [15], seabream (Sparus aurata) [16], and zebra sh (Danio rerio) [8]. Nevertheless, few studies have shown that dietary Schizochytrium sp.…”

Potential of Microalgae Biomass for the Sustainable Production of Bio-commodities

“…It is worth noting that the pool of bioactive pigments of microalgae origin we currently have access to is still limited to only the species so far isolated (Guiry 2012;Appeltans et al 2012 (Table 1), finding potential application as feed in aquaculture (Gimpel et al 2015;García et al 2017;Byreddy et al 2018) and also as food supplement since such molecules have been reported to be beneficial for cardiovascular and inflammatory disorders. PUFAs are currently mainly derived from fish oils, whose production is however rising several concerns for the long-term sustainability.…”
