Effect of dietary astaxanthin on growth, body color, biochemical parameters and transcriptome profiling of juvenile blood parrotfish (Vieja melanurus ♀ × Amphilophus citrinellus ♂)
2022, Aquaculture ReportsCitation Excerpt :The apoa1b and apodb genes related to lipid metabolism were downregulated in the skin of the Wk6ASTA+ and Wk12ASTA+ groups, this reduction may be due to a decrease in accumulation of fatty acids and cholesterols into high-density lipoprotein (HDL). Ando et al. (1986) and March et al. (1990) have described the significant role of HDL in carrying fatty acids and astaxanthin in Atlantic salmon. Because of the hydrophobic attribute of carotenoids, they are reported to be linked with fatty acids and transported via the intestine and blood circulation (Vo et al., 2021).
Effects of natural astaxanthin from microalgae and chemically synthetic astaxanthin supplementation on two different varieties of the ridgetail white prawn (Exopalaemon carinicauda)
2021, Algal ResearchCitation Excerpt :The difference may be caused by the difference in body scale (0.6 ± 0.1 g vs 2.3 ± 0.3 g) and growth stage (juvenile vs adult). It was reported that the deposition of carotenoids was lower at the young stage in salmonids [28,29], and even the flesh pigmentation only occurs after reaching certain minimum size or body weight [28,30]. Different from the uniform effects of improved pigmentation of Ax to aquatic animals, the effect of dietary Ax on growth performance of aquatic animals varies at different developmental stages, or under different environment for different species [2,5].
Effects of dietary cholesterol on astaxanthin transport in plasma of Atlantic salmon (Salmo salar)
2013, Comparative Biochemistry and Physiology - B Biochemistry and Molecular BiologyCitation Excerpt :The biochemical mechanisms involved in carotenoid absorption in fish are considered similar to that of mammals and involve the following steps: 1) disruption of the food matrix and molecular linkages; 2) uptake in lipid droplets; 3) formation and uptake in micelles; 4) uptake in enterocytes and; 5) incorporation for transport into chylomicrons (van het Hof et al., 2000). Uptake of Ax and Cx from the intestine is slow, approximately 18–24 h (March et al., 1990). The blood clearance rate of these carotenoids depends on the transport and cellular uptake of carotenoids from blood lipoproteins (Guillou et al., 1992).
