Aquatic organisms have various pigments contained in their body and may be an important characteristic for the consumer choice. Carotenoids are the main group of pigments present in aquatic organisms and play an important role not only in colouring but also in the growth, reproduction and maintenance of these animals. As aquatic animals do not have the ability to synthesize carotenoids, they must be ingested in the food, and in some cases, they are converted into forms that are possible to store or use in the animal metabolism. In this work, information was collected about the colour characteristics of aquatic organisms and their influence on aquaculture. Various dietary ingredients, such as vegetables and microorganisms, may be potential sources of pigments for aquaculture species, reducing production costs and dependence on synthetic sources of carotenoids. Some species with aquaculture potential may be better studied in terms of the ability to use carotenoid pigments and their function in the body.

类胡萝卜素颜料作为水生生物食品添加剂的用途及其功能作用

水生生物体内含有各种色素，可能是消费者选择的重要特征。类胡萝卜素是水生生物中主要的色素，不仅在着色方面而且在这些动物的生长，繁殖和维持中都起着重要作用。由于水生动物不具有合成类胡萝卜素的能力，因此必须将其摄入食物中，在某些情况下，它们会转化为可能在动物新陈代谢中存储或使用的形式。在这项工作中，收集了有关水生生物的颜色特征及其对水产养殖影响的信息。各种饮食成分（例如蔬菜和微生物）可能是水产养殖物种色素的潜在来源，降低生产成本并减少对类胡萝卜素合成来源的依赖。在使用类胡萝卜素色素的能力及其在人体中的功能方面，可以更好地研究某些具有水产养殖潜力的物种。
