To better understand fish life life cycles, their migratory patterns during spawning season must be looked at. Some fish make journeys back to where they were born, or can only give birth in certain types of waters. The way fish move to make this journey helps scientists classify them into different groups. These groups do not hold any taxonomic sbustance and does not mean the fish are more or less related. Fish that live part of their lives in freshwater and part of their lives in salt water are called diadromous fish. This classification alerts whoever is studying the fish to their unique spawning behaviors and can be further broken down to a more psecific point. Anadromous fish are born in fresh water and then spend most of their lives in salt water before returning to freshwater to spawn. The salmon and its journey upstream to spawn is one of the most common examples, although stripped bass and sturgeon are other examples. Catadromous fish are the opposite. These fish are live in fresh water but journey to the sea to spawn. A common example of this type of fish are eels. This information is important to understanding the fish and in a practical sense, because it is necessary to know how certain buildings and structures will be affecting the aquatic life. If diadromous fish live in a river or off the coast, then they will need to be able to maintain access to the other in order to complete their life cycle and maintain a healthy population.
