Pelvic fins play a role in stabilization of the body during swimming. The bony fish pelvic fin is simple and is supported on a flat-lying triangular plate, somewhat similar to that of the female of the shark Falcatus. Pelvic fins of all sexually mature male chondrichthyans, however, also feature extensions of the fin axis that form sperm conducting ducts for internal fertilization of females. These paired structures, the claspers, are characteristic of adult male Chondrichthyes.
Chondrichthyans related to the modern chimaeroids also develop a tall dorsal process and a specialized first radial armed with denticles (pre-pelvic tenaculum), as seen in a relatively primitive state in Echinochimaera snyderi.

Where is the location of the pectoral fin and pelvic fin in the perch?
The pelvic fin is in the bottom; toward the front side of the middle. The pectoral fin is on the bottom, in the front. The pectoral fin helps control the direction the perch moves. The pelvic fin also controls the direction it moves. The anal fin is in the bottom back side and helps the fish balance. The dorsal fins are on top, one in the middle one it the back and stabalize the fish and aid in sharp turns. The caudal fin, or the tail, is in the back and helps to propel the fish through the water.
