Expert Solution

Two types of aquatic life migrations:
1. Anadromous migration: Migration of life forms from the marine environment to freshwater environment for spawning
Ex: Sea lamprey, Salmon, and striped bass

2. Catadromous migration: Migration of life forms from the freshwater environment to marine environment for spawning
Ex: Eels

3. Amphidromous migration: Migration of life forms from sea to freshwater and vice versa

The migration of aquatic organisms occurs for several reasons.
i. Spawning
ii. Feeding
iii. Nursery grounds
