The rainbow trout thymus is a paired organ, organized in 3 adjacent zones. The gland lying on a thick connective tissue layer, is covered by a thin epithelial capsule. Cellular components of thymus are essentially the thymocytes and the epithelial cells. Thymocytes occur mainly in the inner and outer zones but neither cortex nor medulla are clearly delimited. Septa represent a typical epithelial structure associated with thymocytes and blood vessels. Thymus is well vascularized and electron microscopy demonstrates a characteristic relationship between vascular system and lymphoid tissue.
虹鳟鱼的胸腺是一对器官，由三个相邻区域组成。该腺体位于一层厚厚的结缔组织上，被一层薄的上皮包膜覆盖。胸腺的细胞成分主要是胸腺细胞和上皮细胞。胸腺细胞主要出现在内部和外部区域，但皮质和髓质均无明显界限。间隔是一种与胸腺细胞和血管相关的典型上皮结构。胸腺血管丰富，电子显微镜显示了血管系统与淋巴组织之间的特征性关系。
