“…Previous researches have declared that a low level dietary inclusion of Ulva meal (3-5 %) enhanced growth, feed utilization, immune response, and lipid mobilization in numerous finfish species such as gilthead seabream (Wassef et al, 2005), tilapia (Ergün et al, 2009), rainbow trout , mugil Mugil cephalus (Wassef et al, 2001), black sea bream Acanthopagrus schlegeli (Nakagawa et al, 1993) and snakehead Channa striatus (Hassan and Hashim, 1995). Other studies have shown that a 5% or 10% inclusion of dietary Ulva meal had no negative effects on the growth performance of juvenile European seabass Dicentrarchus labrax (Valente et al, 2006), tilapia , and rainbow trout, Oncorhynchus mykiss of different sizes (Güroy et al, 2013;Dantagnan et al, 2009;SolerVila et al, 2009).…”
