Salinity is a regulating factor (Fry, 1971 Brett, 1979), of greatest importance to diadromous and semi-anadromous fish. In order to keep in balance, fish in sea water must drink copiously and continually excrete salt, while in fresh water they must acquire salts and excrete water. Fish which live in both media at different...

Anadromous fish—These fish are born in fresh water, swim to the ocean as adults, and return to their birthplace to spawn. The alewlfe, American shad, and salmon are examples of anadromous fish. 

Brook trout [Salvdimsfontinalis] have both migratory (anadromous) and non-anadromous populations. Fish from each type were tested for their responses to home-stream water. Both preferred home stream over control water but were equally attracted to water from their home-stream and from an unfamiliar stream. Therefore, specific local odors may not be critical cues. Furthermore, anosmic fish made the same choices, indicating that taste may be involved. In the non-migratory population, responses to home-stream water were noted only in summer, not in winter (Keefe and Winn, 1991).

While the role of carotenoid photoprotection seems well justified in copepods, it is more obscure in the cladocera [16,41]. Sub-Arctic alpine copepods (Hetero-cope) were found to have ten times more carotenoids than sympatric populations of cladocerans, and even low-land transparent copepods have higher carotenoid levels than highly light-exposed Daphnia [41]. Carotenoids are also widespread in fish, notably anadromous salmonids, yet the role of carotenoids in photoprotection in these species is not settled.

Chemical signals are also involved in fish migration. Fish which, like eels, spawn in the sea and swim up rivers to feed and mature are called catadromous, whereas those, like salmons, which perform the reverse movement are called anadromous. 

Furthermore, the dams huilt for hydroelectric power plants, for example, cut off access to the spawning grounds of anadromous, migratory salmon or the American shad. These fish must return upriver to lay their eggs. To facilitate the return journey, fish lifts, ladders, or elevators are in place at many dams. These structures, which help fish move upstream, also help to avoid the disruption of the local hahitat. 

Saltwater fish are often classified in the fishing industry as anadromous, groundfish, or pelagic fish.
