Summary: | In the present study, the location, histology and number of corpuscles of Stannius (Sc), which are endocrine glands associated with the kidneys of teleost fish, were investigated for the first time in Lake Van fish (Alburnus tarichi), an anadromous and endemic inhabiting Turkey's Lake Van Basin. The Sc, which were ovoid or spheroid and white or cream in colour, were found to vary in number between three and five among the examined fish. The glands were located in the caudal part of the kidney, and either partially or completely embedded, and found to be present on both the ventral and dorsal surface of either side of the caudal part of the kidney. The Sc were surrounded by a connective tissue capsule that penetrated and divided the gland into incomplete lobules. Two types of cells were determined in the parenchyma of the gland. Type‐I cells were predominant throughout the parenchyma and larger than the second (type‐II). In the type‐I cells, the cytoplasm was observed as weakly or moderately eosinophilic with haematoxylin and eosin staining and weakly or moderately acidophilic with Mallory's triple staining. In the type‐I cells, the cytoplasm exhibited weak to moderate periodic acid‐Schiff staining and slight or uniform staining with aldehyde fuchsin. The type‐II cells were round, had a darkly stained spherical nucleus and were dispersed among the type‐I cells. They displayed no cytoplasmic staining with the abovementioned stains. |
