Abstract

The work examined the influence of experimental anoxia on the content and qualitative composition of carotenoids in the tissues of the bivalve invader Anadara kagoshimensis (Tokunaga, 1906) under experimental conditions. The oxygen content in the water was reduced by nitrogen sparging for five hours. The exposure lasted three days. Tissue samples (gills, foot, and hepatopancreas) were collected before the experiment (control), as well as on the first, second, and third day of the experiment. The water temperature was maintained at 16–17°C. It is shown that, in anoxia, carotenoids are redistributed in favor of respiratory surfaces. In the gills, the proportion of pink-scarlet pigments, that is, pectenolone and its esters (pectenolone complex), increases. The relative content of pectenolone esters significantly increases in all studied organs; there is also a slight increase observed in the levels of allo-, diato-, and zeaxanthin esters.

缺氧对双壳类入侵者Anadara kagoshimensis组织中类胡萝卜素含量和组成的影响（Tokunaga，1906年）

摘要

这项工作研究了实验性缺氧对双壳入侵者山adAnadara组织中类胡萝卜素含量和定性组成的影响。（Tokunaga，1906）在实验条件下。通过氮气鼓泡五小时来减少水中的氧气含量。暴露持续了三天。在实验之前（对照）以及实验的第一天，第二天和第三天，收集组织样本（g，足和肝胰腺）。水温保持在16–17°C。结果表明，在缺氧状态下，类胡萝卜素重新分布，有利于呼吸表面。在the中，粉红色的颜料（即果胶烯酮及其酯（果胶酮配合物））的比例增加。果胶酮酯的相对含量在所有研究的器官中均显着增加。还观察到了脲基，DIATO和玉米黄质酯的含量略有增加。
