Lake Van is the largest lake in Turkey. It is one of the few soda lakes in the world. Its water is brackish and soda. The lake water has a salinity rate of 19‰ and a pH of 9.8. The salty-soda content of the lake greatly limits biodiversity. Since the Lake Van fish is anadromous, it migrates from the extreme conditions of Lake Van to the freshwater pouring into the lake to spawn. In the same way, once they have emerged from the eggs, the newly hatched fish return to the lake environment to feed again. In this study, the changes in Lake Van fish gill mucus cell histochemistry were examined using different histological stains. The area and density of the mucus cells were observed to have changed in the aquatic areas of different physicochemical properties due to reproductive migration. The intensity of the mucus staining was also found to vary in different aquatic locations and gill regions. As a result, it was clearly demonstrated that mucus cell glycoprotein contents and levels found in Lake Van fish gills varied in different lake freshwater and aquatic environments. In addition, it was determined that the area and density of the mucus cells varied during reproductive migration. It is thought that the change in mucus cells was caused by salinity, pH, and bacterial and parasitic infections encountered in different aquatic environments. These changes in the gill mucus cells play an important role in the aquatic adaptation of fish.

范fish鱼(Alburnus tarichi)生殖迁移过程中g黏液细胞的研究。

范湖是土耳其最大的湖泊。它是世界上为数不多的苏打湖之一。它的水微咸和苏打水。湖水的盐度为19‰,pH为9.8。湖中的盐碱含量极大地限制了生物多样性。由于范克湖的鱼类过旺,因此从范克湖的极端条件迁移到涌入湖中的淡水中产卵。同样,新孵出的鱼一旦从卵中出来,就会回到湖泊环境中重新觅食。在这项研究中,使用不同的组织学染色检查了范克鱼fish黏液细胞组织化学的变化。观察到由于生殖迁移,在具有不同理化特性的水生区域中,粘液细胞的面积和密度发生了变化。还发现粘液染色的强度在不同的水生位置和g区域中变化。结果,清楚地证明了在范湖鱼g中发现的粘液细胞糖蛋白含量和水平在不同的湖泊淡水和水生环境中变化。另外,确定在生殖迁移期间粘液细胞的面积和密度变化。据认为,粘液细胞的变化是由盐度,pH以及在不同水生环境中遇到的细菌和寄生虫感染引起的。ill粘液细胞的这些变化在鱼类的水生适应中起重要作用。清楚地表明,范湖鱼g中发现的粘液细胞糖蛋白含量和水平在不同的淡水和水生环境中有所不同。另外,确定在生殖迁移期间粘液细胞的面积和密度变化。据认为,粘液细胞的变化是由盐度,pH以及在不同水生环境中遇到的细菌和寄生虫感染引起的。ill粘液细胞的这些变化在鱼类的水生适应中起重要作用。清楚地表明,范湖鱼g中发现的粘液细胞糖蛋白含量和水平在不同的淡水和水生环境中有所不同。另外,确定在生殖迁移期间粘液细胞的面积和密度变化。据认为,粘液细胞的变化是由盐度,pH以及在不同水生环境中遇到的细菌和寄生虫感染引起的。ill粘液细胞的这些变化在鱼类的水生适应中起重要作用。
