Effects of dietary supplementation of golden apple snail (Pomacea canaliculata) egg on survival, pigmentation and antioxidant activity of Blood parrot

Abstract

This study aims to evaluate the effects of supplementing golden apple snail (Pomacea canaliculata) eggs powder (EP) in the diet as a source of natural carotenoids on survival, pigmentation and antioxidant activity of Blood parrot. A total of 90 fish were divided into three treatment groups with three replicates per treatment. Blood parrot were fed with diets containing 0 (control), 5 % (EP 5 %), and 15 % (EP 15 %) dry powder of golden apple snail egg for 60 days, and nine fish per group were sampled at 20, 40, and 60 days. No differences in survival of the fish among treatments were found throughout the experiment. The body coloration of Blood parrot was enhanced in the skin and caudal fin with increasing content of golden apple snail egg powder in the diet. At the end of the experiment, the carotenoid content in the caudal fin and the number of scale chromatophores of the fish fed dietary with EP were higher (P < 0.05) than those of the control group. The EP 15 % treated fishes showed a significant higher (P < 0.05) in the activities of SOD after 60 days, but we could not observe significant changes (P > 0.05) in CAT activities. Results demonstrated that golden apple snail eggs can be used as a colorant to promote the pigmentation efficacy of Blood parrot.

Enhancement of colour quality, growth, and health status of rainbow Kurumoi fish Melanotaenia parva through dietary synthetic carotenoids supplementation

“…The basal feed treatment obtained more non pigmented cells (Table 6). It was in line with Yang et al (2016) in blood parrot fish which showed xanthophores and erythrophores escalation when fed using Pomacea canaliculata eggs. Yang et al (2016) also stated that feed contained different kinds of carotenoids would generate colour differences.…”

The percentage of chromatophore showed that carotenoids addition affected the chromatophore appearance in the integument of Kurumoi rainbowfish.…”

Effect of Shrimp Feed Supplemented with Astaxanthin on Golden Apple Snail Pomacea diffusa

“…and rami Boehmeria nivea obtained a 6:1 feed conversion and food acceptance may vary according to the mollusk' age. Pomacea can accumulate these pigments and convert them to astaxanthin only during the reproductive period as a way of protecting eggs and larval forms, as described by Yang et al (2016). Still, in the mentioned study, the greatest accumulation of astaxanthin (when added to the diet) was observed in the Pomacea's hepatopancreas.…”

“…According to Dreon et al (2004), the carotenoids of Pomacea eggs with proteins form a complex called ovorubin which is responsible for the protection against microsomal oxidation. Due to the properties of these eggs, studies have been directed to their use in fish feeding to enhance color in fancy carp (Cyprinus carpio) (BOONYAPAKDEE et al, 2015), parrots as an antioxidant and feather coloring (YANG et al, 2016), also to improve egg quality in Arabic chicken (NUSANTORO et al, 2020).…”
