Salmon and striped bass are well-known anadromous fish, and freshwater eels are catadromous fish that make large migrations. The bull shark is a euryhaline species that moves at will from fresh to salt water, and many marine fish make a diel vertical migration , rising to the surface to feed at night and sinking to lower layers of the ocean by day.
Because the eels are catadromous (living in fresh water but spawning in the sea), dams and other river obstructions can block their ability to reach inland feeding grounds. Since the 1970s, an increasing number of eel ladders have been constructed in North America and Europe to help the fish bypass obstructions.

They are catadromous, spending their adult lives in freshwater, but migrating to the ocean to spawn. Eels are an important food fish and some species are now farm-raised, but not bred in captivity. Many populations in the wild are now threatened, and Seafood Watch recommend consumers avoid eating anguillid eels.
This catadromous breeding system [8] also ensures randomised mating, creating a panmictic population. [7] The New Zealand longfin eel is a very long-lived fish, with records of females reaching 106 years old and weighing up to 24 kg. [5] [9] They have the slowest growth rate of any eel species studied, just 1–2 centimetres a year. [10]
This fish lacks scales but its body surface is textured with knobbles. [1] The gill opening is large [1] and each gill has two orange stripes. [2] This fish lives in rivers, estuaries, and coastal ocean waters. It is catadromous; adults spawn on mudflats at the river mouths, and after hatching, the juveniles swim upstream to freshwater river ...
European eels live through 5 stages of development: larva (leptocephalus), glass eel, elver, yellow eel, and silver eel.Adults in the yellow phase are normally around 45–65 centimetres (18–26 in) and rarely reach more than 1.0 metre (3 ft 3 in), but can reach a length of up to 1.33 metres (4 ft 4 in) in exceptional cases.

The barramundi (Lates calcarifer), Asian sea bass, or giant sea perch (also known as dangri, apahap [2] or siakap) is a species of catadromous fish in the family Latidae of the order Carangiformes. The species is widely distributed in the Indo-West Pacific , spanning the waters of the Middle East , South Asia , Southeast Asia , East Asia , and ...
