The 53 pages that link to Fish migration, each with the reason it gives.

• Environmental flowRelated: Flow cues and passable water levels can determine whether migrations succeed.

• Ray-finned fishRelated: Migratory ray-finned species connect rivers, lakes, and oceans across their life cycles.

• Fish locomotionRelated: Swimming capacity constrains how far and through what currents migrating fish can travel.

• DamRelated: A dam can block routes between spawning grounds and other habitats.

• Freshwater fishRelated: Seasonal and life-stage movements connect feeding grounds with spawning sites.

• WaterfallRelated: A waterfall can obstruct upstream movement for fish unable to leap or climb it.

• Fish ladderRelated: Many ladders are intended to preserve migrations interrupted by dams.

• Ram ventilationRelated: Long-distance swimming can sustain ventilation while animals travel.

• SpawningRelated: Many species migrate specifically to reach suitable spawning sites.

• Thermal pollutionRelated: Temperature changes can shift migration routes and access to spawning habitat.

• Fish spawningRelated: Many fish migrate to reach spawning areas or suitable conditions for reproduction.

• River regulationRelated: Changed flows and barriers can disrupt migration cues and routes.

• Nile perchRelated: Seasonal movements influence where Nile perch feed and where fisheries can catch them.

• Marine fishRelated: Marine fish may cross entire ocean basins or move between sea and freshwater.

• AnchovyRelated: Anchovy schools shift with food availability, temperature, and spawning needs.

• Atlantic herringRelated: Herring move seasonally among spawning, feeding, and overwintering areas.

• Fish trapRelated: Fixed traps are often placed where migrating fish pass through predictable routes.

• Freshwater fisheriesRelated: Migration connects fishing grounds and spawning or feeding habitats across inland waters.

• SawfishRelated: The routes and timing of sawfish movements remain uncertain in many parts of their range.

• Atlantic menhadenRelated: Seasonal movements connect menhaden feeding grounds, nurseries, and spawning areas.

• GadidaeRelated: Seasonal migrations bring some gadid populations to feeding and spawning grounds.

• IchthyologyRelated: Migration routes and environmental cues remain difficult to track for many species.

• Skipjack tunaRelated: Skipjack moves across ocean regions as temperature and food availability change.

• Water diversionRelated: Reduced or rerouted flows can obstruct migration to spawning and feeding grounds.

• HaddockRelated: Haddock move among feeding and spawning areas, though patterns vary by stock.

• European perchRelated: Perch may move between deeper feeding areas and shallower spawning grounds.

• European seabassRelated: Seasonal movements connect seabass feeding grounds, overwintering areas, and spawning regions.

• Grass carpRelated: Adults migrate into flowing rivers to spawn.

• Madeira RiverRelated: Dams and rapids influence routes used by migratory fish in the Madeira basin.

• Pacific sauryRelated: Seasonal migrations shape the species’ distribution and availability to fisheries.

• FishermanRelated: Seasonal migrations shape where and when fishermen can catch particular fish.

• Mahi-mahiRelated: Mahi-mahi move widely through warm waters, with seasonal patterns shaped by temperature and food.

• Murray codRelated: Seasonal movements connect cod habitat and spawning areas within rivers.

• BarramundiRelated: Movement between inland waters and coastal spawning areas shapes barramundi’s life cycle.

• Big-game fishingRelated: Seasonal migrations help determine where and when large pelagic fish can be found.

• TambaquiRelated: Seasonal movements connect tambaqui feeding grounds and spawning areas.

• CaranxRelated: Movement among reefs, coastlines, and open water shapes the distribution of some trevallies.

• Coastal fishRelated: Some coastal species shift among habitats as seasons or life stages change.

• Common breamRelated: Bream move between feeding grounds and spawning areas within river and lake systems.

• Fishing weirRelated: Weirs intercept fish moving along established routes.

• Flathead grey mulletRelated: Adults migrate toward the sea to spawn, while juveniles enter coastal waters.

• GalaxiidaeRelated: Many galaxiids move between freshwater and the sea during their life cycles.

• IlishRelated: Hilsa migration connects coastal waters with inland river reaches.

• TarponRelated: Tarpon move among coastal, estuarine, and sometimes freshwater habitats during their life cycle.
