What are perch and bass skeletons made of in fish?

Perch and bass skeletons, like those of most bony fish, are primarily composed of bone, which is a hard, mineralized tissue. The bones are made up of a matrix that contains collagen fibers and inorganic minerals, primarily hydroxyapatite, which gives them strength and rigidity. Additionally, some parts of their skeletal structure may have cartilage, a flexible connective tissue that provides support and flexibility. Overall, the bony skeleton supports the fish's body and protects vital organs.
