Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
The round whitefish is different than other whitefish by having one flap between the nostril openings (instead of two). It can grow up to 50 centimetres (20 in) in length [6] and typically grow in increments of 55–65 millimetres (2.2–2.6 in) annually. Most of its growth takes place in its first five years of life. [8]

Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. [1] Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn; and catadromous, in which adult fish live in fresh water and migrate into salt ...
