Rainbow trout farm effluent as a potential source of feed and medium for mass culture of Artemia parthenogenetica

Substitution of microalgae by bioflocs as a food source for the brine shrimp Artemia franciscana

“…Although the bioflocs produced in our study contained significantly less protein and lipid than the microalgae used, this was not reflected in the proximate composition of the Artemia fed under different feeding regimes. In our study, protein, lipid and ash content of Artemia fed on bioflocs was in the range of previous studies, which reported 45%–58% protein and 9%–19% lipid for Artemia fed with bioflocs (Anh et al, 2009), aquaculture effluent (Gharibi et al, 2021) and microalgae (Turcihan et al, 2021), with the ash content in our study being in the range of the first two studies (11%–22%).…”

“…In the present study, the amounts of fatty acids in cultured Artemia were affected by the diet, as treatments fed more bioflocs had significantly higher levels of C18:1n‐9, ARA, EPA, MUFA and total n‐6 PUFA. Our results on EPA (except from the control treatment), DHA, ARA and ALA were in the range of values reported in Artemia fed on microalgae as a main food supplemented by bioflocs and in Artemia fed on aquaculture effluent (Toi et al, 2013; Gharibi et al, 2021), whereas LA and DHA were, respectively, higher and lower than ranges reported in the literature (respectively, 14–17 and 6–8 mg g −1 DW (Toi et al, 2013; Turcihan et al, 2021). These differences may be due to the different types of food offered to Artemia , including the strains of microalgae, quality and quantity of produced bioflocs, and the ratio of microalgae and of bioflocs in the diet.…”

Biological Impact of Photoperiod on Fairy Shrimp (Branchinecta orientalis): Life History and Biochemical Composition

“…Fatty acids are involved in organismal adaptive responses to any changes in the environment, participate in cellular energy provision and physiological processes, and regulate biochemical reactions [ 67 ]. It has long been recognized that culture conditions play a major role in determining the quantity and quality of the fatty-acid profile in aquatic animals [ 64 , 67 , 68 ]. Our results showed that the fatty-acid content of fairy shrimp was affected by the light/dark cycle.…”
