Despite the growing interest in microalgae as sustainable sources of nutrients in complete feeds and recent findings indicating their good potential as a bulk feedstuff for formulated aquafeeds, their dietary inclusion, even at low level, often implies declining nutrient and energy availability in carnivorous fish species (Sorensen et al., 2016; Kousulaki et al., 2015; Tibaldi et al., 2015; Tulli et al., 2012; Burr et al., 2011). A possible adverse role of microalgae cell wall structure and composition on nutrient availability has been hypothesized by different authors. This study was carried out to test sonication as a possible post production cell wall disruption technique to increase the digestibility of Chlorella sorokiniana freeze dried biomass in rainbow trout.
