本章概述了关于鱼类的普遍应激反应以及虾青素(ASX)对鱼类可能的生物学和营养作用的知识，虾青素是一种典型的极性胡萝卜素。这是因为类胡萝卜素是一种独特的天然色素，在动物体内具有多种生物活性。生物体暴露于应激源可能会导致一系列的生化和生理变化。这些变化是由生物体水平的神经内分泌系统调节的。类胡萝卜素是自然界中最常见的一类色素。它们存在于生命的三个领域：真细菌、古细菌和真核生物。各种来源的饮食类胡萝卜素已被应用于鱼的着色。水产养殖中经常使用的类胡萝卜素来源是合成的ASX、红酵母P。红发酵母菌、绿色微藻雨生红球藻、龙虾、螺旋藻、甲壳动物粉、红辣椒、万寿菊等。
This chapter summarizes knowledge about the generalized stress response in fish and possible biological and nutritional actions of astaxanthin (ASX), a typical polar carotenoid, on fish. This is because carotenoids are unique natural pigments, which have many kinds of biological activities in animals. Exposure of organisms to stressors may result in a series of biochemical and physiological changes. These changes are mediated by the neuroendocrine system at the organismal level. Carotenoids are one of the most common classes of pigments that occur in nature. They occur in three domains of life: eubacteria, archaebacteria, and eukaryotes. A variety of sources of dietary carotenoids have been applied for coloration of fish. The sources of carotenoids often used in aquaculture are synthetic ASX, red yeastP. rhodozyma, green microalgaeHaematococcus pluvialis, krillEuphausia superba, algaSpirulina spp., crustacean meal, red pepper paprika, marigold flowers, etc.
