More About Fish Migration
Fish migration is the movement of fish from one area to another, often undertaken in order to find food or to reproduce. Fish can migrate in a number of ways, including swimming long distances, using currents or tides to move, or hitching a ride on objects such as logs or boats. Some fish, such as salmon, migrate annually, while others, such as eels, may migrate several times during their lifetime.
Oceonodramous Fish
Oceanodramous Fish are a type of fish that live in the ocean. They are very good swimmers and can move quickly through the water. They have a long, streamlined body and a powerful tail that helps them move quickly through the water. They have a large mouth and sharp teeth that help them catch prey. They typically live in warm water environments and can be found in both the Atlantic and Pacific oceans.
Anadromous Fish
Anadromous fish are fish that live in the ocean but migrate to freshwater to spawn. After spawning, the adults return to the ocean. Some common anadromous fish include salmon, trout, and eels.
Catadromous Fish
Catadromous fish are fish that live in freshwater environments but migrate to the ocean to spawn. After spawning, the adults return to freshwater to live out their lives. Catadromous fish include eels, salmon, and lampreys.
