How do fish move?

This is a relatively slow type of locomotion and a good deal of energy is needed to propel (move) the fish. Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side.

Why does a fish’s fin move side to side?

As the fin moves side to side, pressure builds up on the thrusting side of the fin and decreases on the trailing side. The gradient causes water to move sideways across the body. This lateral motion can disrupt the boundary layer, the layer of water right next to the moving body (the fish), which is crucial to reducing drag.

What is sub-carangiform locomotion in fish?

Sub-carangiform The sub-carangiform group has a more marked increase in wave amplitude along the body with the vast majority of the work being done by the rear half of the fish. In general, the fish body is stiffer, making for higher speed but reduced maneuverability. Trout use sub-carangiform locomotion.

More specialised fish include movement by pectoral fins with a mainly stiff body, opposed sculling with dorsal and anal fins, as in the sunfish; and movement by propagating a wave along the long fins with a motionless body in fish with electric organs such as the knifefish.

Can tilapia swim fast?

But they can’t swim as fast as fish using their bodies and caudal fins. As an example of how a fish moves through the water, consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance to movement and enabling the tilapia to cut easily through water.
