This study aimed to determine the effects of 3%, 7%, 11%, and 15% red pepper () supplementation to diet on antioxidant, oocyte development and disease resistance against A210 of jewel cichlid (). Fifteen fish (3.43 g ± 0.03) were stocked to each aquarium and fed ad libitum for 90 days. At the end of the trial, the number of mature oocytes increased by adding 11% and 15% red pepper to the diets. ( < 0.05). Fish fed diets containing 11% and 15% red pepper showed a significant rise in superoxide dismutase (SOD) activity ( < 0.05). In addition, fish fed diets containing 3% and 11% red pepper showed disease resistance against in jewel cichlids. After challenge with , cumulative mortality rates in fish fed with diets containing 3%, 7%, and 11% red pepper were significantly reduced compared to the control group ( < 0.05). Therefore, using 11% red pepper is appropriate to provide resistance against infections, increase fertility and antioxidant levels in jewel cichlids ).
本研究旨在确定在宝石丽鱼饮食中添加3%、7%、11%和15%的红辣椒对其抗氧化能力、卵母细胞发育以及抵抗嗜水气单胞菌A210的抗病能力的影响。每个水族箱放养15尾鱼（3.43克±0.03），随意喂食90天。试验结束时，在饮食中添加11%和15%红辣椒可使成熟卵母细胞数量增加（P<0.05）。喂食含11%和15%红辣椒饲料的鱼超氧化物歧化酶（SOD）活性显著升高（P<0.05）。此外，喂食含3%和11%红辣椒饲料的鱼对宝石丽鱼的嗜水气单胞菌具有抗病能力。在用嗜水气单胞菌攻击后，与对照组相比，喂食含3%、7%和11%红辣椒饲料的鱼的累积死亡率显著降低（P<0.05）。因此，使用11%的红辣椒适合提高宝石丽鱼对嗜水气单胞菌感染的抵抗力、增加繁殖力和抗氧化水平。
