Although vertebrates—a subphylum within the phylum Chordata—are far fewer in number than invertebrates, they differ significantly due to their larger body size, complex and diverse individual structures, and a wide range of physiological and ecological characteristics. Consequently, chordates hold immense importance for human life and activity; they are harvested for their meat, skin, fur, eggs, and oil. Therefore, it is essential to preserve rare and endangered vertebrate species—specifically fish—by studying their ecology, developmental traits, reproduction, and migration patterns, and by developing technologies for their protection and cultivation. As one of the most pressing issues, it should be noted that fish serve not only as a prized food source for humans but also as a valuable raw material.
