摘要

一项为期63天的实验评估了8个水平的红曲霉色素（0、25、50、75、100、150、200和300 mg kg−1）与一种商业色素虾青素(Lucantin®Pink；150 mg kg−1)对小龙虾幼虾生长性能、鱼片品质和血淋巴生化指标（4.71±0.23 g）的影响。增加红曲霉色素（50 ~ 300 mg kg−1）对小龙虾的生长和饲料效率的影响显著高于对照和虾青素（p < 0.05）。饲粮中添加200 mg kg−1红曲红色素的小龙虾最终体重最高，为24.35 g，蛋白质效率（PER）为3.13，蛋白质生产价值（PPV）为58.38% （p<0.05）。添加200 mg kg−1红曲红色素的小龙虾血淋巴中酚氧化酶、超氧化物歧化酶、溶菌酶和一氧化氮合酶的含量最高（p < 0.05）。鱼片颜色质量评价结果显示，添加300 mg kg - 1红曲红色素的小龙虾a*和b*指标最高（p < 0.05）。根据折线回归模型，饲料中红曲红色素对小龙虾最终体重、特定生长率和饲料系数的影响分别为225.6、227.1和228.4 mg kg−1。本研究结果表明，使用225 ~ 230 mg kg - 1水平的红曲红色素对小龙虾的生长性能、鱼片颜色质量和免疫反应有积极影响。建议进一步研究红曲霉色素在其他水生物种（特别是甲壳类动物）饮食中的使用情况，以确定最佳的添加水平并评估潜在的益处。

A 63-day experiment was conducted to assess the impact of using eight levels of Monascus purpureus pigment (0, 25, 50, 75, 100, 150, 200, and 300 mg kg⁻¹) along with a commercial pigment, astaxanthin (Lucantin^® Pink; 150 mg kg⁻¹), in the diet on the growth performance, fillet quality, and hemolymph biochemical indices of juvenile crayfish (4.71±0.23 g) at three replicates. An increment in the supplemented levels of Monascus pigment (50–300 mg kg⁻¹) in the diet of crayfish showed significant increases in most growth and feed efficiency indices when compared with the control and astaxanthin diet (p<0.05). The highest final weight (24.35 g), protein efficiency ratio (PER) (3.13), and protein productive value (PPV) (58.38%) were observed in the crayfish fed the diet containing 200 mg kg⁻¹ Monascus pigment (p<0.05). The highest levels of phenoloxidase, superoxide dismutase, lysozyme, and nitric oxide synthase were measured in the hemolymph of crayfish fed the diet containing 200 mg kg⁻¹ Monascus pigment (p<0.05). The evaluation of fillet color quality showed that crayfish fed the diet containing 300 mg kg⁻¹ of Monascus pigment had the highest values for the a* and b* indices (p<0.05). The optimum dietary levels of Monascus pigment on final weight, specific growth rate, and feed conversion ratio of crayfish, based on the broken-line regression model, were 225.6, 227.1, and 228.4 mg kg⁻¹, respectively. The results of the present study showed that the use of Monascus pigment at levels of 225 to 230 mg kg⁻¹ can have a positive effect on growth performance, fillet color quality, and immune responses of tested crayfish. Further studies are recommended to investigate the use of Monascus pigment in the diets of other aquatic species, particularly crustaceans, to determine optimal inclusion levels and evaluate potential benefits.

期刊介绍： Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture. The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more. This is the official Journal of the European Aquaculture Society.
