Digestibility, growth and pigmentation of astaxanthin, canthaxanthin or lutein diets in Lake Kurumoi rainbowfish,Melanotaenia parva(Allen) cultured species

Abstract

New cultured ornamental fish namely Lake Kurumoi rainbowfish Melanotaenia parva (Allen) run into reduced of colour performances when reared in the aquaria, consequently, fish feed must be added with carotenoids as a pigment source. The aim of this study was to evaluate the digestibility, growth and pigmentation of astaxanthin, canthaxanthin and lutein in diet. Apparent digestibility coefficients (ADC) of dry matter, lipid, protein, carotenoids, growth and pigmentation were studied in twenty fish after 14 and 56 days of observation. The single‐dose supplementation of 100 mg/kg of astaxanthin, canthaxanthin, or lutein diets on fish was fed by apparent satiation. The basal diet without carotenoids was used as control. The result showed that the ADC of carotenoids of test diets was higher compared to control. Fish fed astaxanthin diet had higher survival rate (96.67 ± 2.89%), colour measurements of lightness (57.60 ± 7.46%), a*‐values (4.66 ± 1.20), total carotenoids content in skin (33.75 ± 5.02 mg/kg) and muscle (2.16 ± 0.74 mg/kg). Astaxanthin also increased the growth after 14 days (2.00% ± 0.19%/days) but there was no significantly different at the end of experiment. The yellowish‐orange colour performance was more rapidly achieved by fish fed astaxanthin diet after 28 days experimentation. These values suggested that dietary carotenoids were required and astaxanthin diet was superior to other diets for skin pigmentation of Lake Kurumoi rainbowfish.

Dietary astaxanthin differentially affected the lipid accumulation in the liver and muscle of the marine teleost, tiger pufferTakifugu rubripes

“…Considering that the group with 50 mg/kg ASTX had the best growth performances, the elevation of lipid content and SFA or MUFA content in this group could possibly be a side effect of good growth performances. In several fish species such as Atlantic salmon Salmo salar (Christiansen & Torrissen, ), common carp Cyprinus carpio (Jagruthi et al, ) and Lake Kurumoi rainbowfish Melanotaenia parva (Meilisza et al, ), the growth‐promoting effects of ASTX have been demonstrated. In terrestrial animals, ASTX has also been shown to have positive effects on health status of liver and intestine (Bhuvaneswari et al, ; Costanzo et al, ; Yang et al, ; Zhang et al, ).…”

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

“…The result in Table 2 showed that carotenoids tested feed directly affected the growth and survival rate of the Kurumoi rainbowfish (Meilisza et al, 2017). Niu et al (2017) and Parisanti et al (2011) reported similar results.…”

“…It was assumed that lutein absorption was lower than two other carotenoids. The statement was supported by the study by Yuangsoi & Jintasathaporn (2011) and Meilisza et al (2017) The health status of the tested fish was discovered through blood profiles. The erythrocyte content of a healthy teleost species generally ranges in 1.05−3.0×10 6 cell/mm 3 (Robert, 2012).…”

“…The applied dosage was considered as effective dosage for pigmentation, growth, and health of some fish species (Del Villar-Martinez et al, 2013;Nguyen et al, 2014;Pham et al, 2014). The digestibility of 100 mg/kg dosage has been determined based on the results in the previous experiment in Kurumoi rainbowfish (Meilisza et al, 2017).…”

“…Several pigments which obtained by carotenoid are lutein (yellow-green), carotene (orange), doradexanthin (yellow), zeaxanthin (yellow-orange), canthaxanthin (orangered), astaxanthin (red), echinenone (red), and taraxanthin (yellow) (García-Chavarría & Lara-Flores, 2013). Various study about pigmentation on ornamental fish has been widely observed using extracted carotenoid and astaxanthin is the most commonly used and it showed effective (Meilisza et al, 2017) *NFE = 100−(crude protein+fat+fiber+ash) NS = no significant amongst treatments to result in colour enhancing on different ornamental fish species (Niu et al, 2014;Das & Biswas, 2016). The other application of different source of carotenoids, such as canthaxanthin and lutein, is also proved in enhancing the colour of ornamental fish and affected the health status of the fish positively (Talebi et al, 2013;Rahman et al, 2016;Chow et al, 2016;Meilisza et al, 2018).…”
