课题组关于藻类虾青素的论文成果《Effects of Dietary Supplementation with Algal Astaxanthin on Growth, Pigmentation, and Antioxidant Capacity of the Blood Parrot (Cichlasoma citrinellum × C. synspilum)》在最新一期的Journal of Oceanology and Limnology期刊（Vol.36, No.5, P:1851-1859, 2018) 见刊发表。 为探究藻类天然虾青素对鹦鹉鱼生长、色素沉着和抗氧化能力的影响，本研究通过饲养实验对饲喂虾青素的鹦鹉鱼进行了观察。选择组织总抗氧化能力（TAC），超氧化物歧化酶（SOD），过氧化氢酶（CAT）和马来酸二醛（MDA）作为其抗氧化能力的量度。所有接受虾青素（来自微藻Haematocccus pluvialis）的鱼每公斤补充400毫克虾青素，饲喂50天后呈现粉红色皮肤，与饲喂基础鱼的鱼呈现灰色外观形成对比。饮食（非虾青素饮食作为对照组）。取出皮肤和鳞片样品用于分析总类胡萝卜素和虾青素含量，并且接受虾青素的鱼显示出比对照组显着（p <0.05）更高的浓度，表明通过膳食虾青素显着改善了该鱼的色素沉着。与对照鱼相比，色素鱼具有较低的SOD，CAT和MDA以及较高的TAC。可以得出结论，补充膳食虾青素可以有效地增强这种鱼的抗氧化能力。

  Abstract：An algal astaxanthin feeding trial was carried out to observe the improvement of blood parrot Cichlasoma citrinellum x C. synspilum, with astaxanthin could enhance its growth, skin coloration and antioxidant capacity. Tissue total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT) and maleic dialdehyde (MDA) were chosen as measures of its antioxidant capacity. All fish which received an astaxanthin (from micro-alga Haematocccus pluvialis) supplemented diet with 400 mg of astaxanthin per kg-1, displayed a pink-colored skin after 50 days of feeding in contrast to the grayish appearance displayed by fish fed with the basal diet (a non-astaxanthin diet as the control group). Samples of skin and scales were withdrawn for analysis of total carotenoids and astaxanthin content, and fish receiving astaxanthin showed significantly (p<0.05) higher concentrations than the control group, indicating that the pigmentation of this fish had been significantly improved by dietary astaxanthin. Compared with the control fish, pigmented fish had lower SOD, CAT and MDA and higher TAC. It can be concluded that supplementation with dietary astaxanthin could effectively enhance the antioxidant capacity of this fish.
