Ameliorating effects of dietary Haematococcus pluvialis on arsenic-induced oxidative stress in rainbow trout (Oncorhynchus mykiss) fillet

Microalga‐ and yeast‐based astaxanthin production via nutrient recovery from wastewater for aquaculture practice: an emerging technology for sustainable development

“…1,2,66 As a super antioxidative substance, astaxanthin could be added into fish diet as a supplement for immunity enhancement and disease resistance. 3,76 Pigmentation Astaxanthin in diet can accumulate in muscle and skin, improving meat quality and ornamental value of aquatic animals. It was reported that in the 86-day culture of Atlantic salmon fed diets supplemented with Phaffia rhodozyma, astaxanthin retention in muscle reached 6.63% of total amount of astaxanthin eaten.…”

“…1,2 As a type of carotenoid with superior antioxidative activity, natural astaxanthin has been widely used as feed supplement and pigment for fish rearing. 3,4 It was reported that the intake of natural astaxanthin could enhance immune response and increase disease resistance of aquatic animals. 5,6 Compared with antibiotics or medicines, the use of natural astaxanthin in fish diet is a more promising option for ecofriendly aquaculture.…”

“…The overuse of antibiotics or medicines in fish rearing not only leads to environmental pollution, but also causes safety problems in food chains 1,2 . As a type of carotenoid with superior antioxidative activity, natural astaxanthin has been widely used as feed supplement and pigment for fish rearing 3,4 . It was reported that the intake of natural astaxanthin could enhance immune response and increase disease resistance of aquatic animals 5,6 .…”

Environmental toxicology of arsenic: current understanding of toxicity, detection, and remedial strategies

“…There are many reports on algae aggravated arsenic exposure to aquatic animals (Milan et al, 2021;Byeon et al, 2021), since algae additively acting with arsenic to increase arsenic uptake and assimilation in aquatic animals. Hence, water systems having high algae and arsenic are posing more bioaccumulation in aquatic animals.…”

Dietary supplementation of archaeal carotenoids improved antioxidative capacity and regulated immune‐related gene expression of golden trout Oncorhynchus mykiss against challenge

“…Nevertheless, the economic loss caused by disease outbreak has threatened the sustainable farming of this species (Cao et al, 2020; Yarahmadi et al, 2016), hence, the disease prevention and cure strategies are needed. It has been reported that dietary supplementation with astaxanthin‐enriched red yeast Phaffia rhodozyma , and microalgae Haematococcus pluvialis have resulted in better antioxidative capacity and health condition of rainbow trout (Kheirabadi et al, 2022; Milan et al, 2021). Our previous study has shown that dietary supplementation of halophilic archaea Halorubrum carotenoids resulted in higher astaxanthin content in the carapace of Litopenaeus vannamei (unpublished data), and enhanced antioxidative capacity and stress tolerance of Litopenaeus vannamei (Xie et al, 2021).…”
