The first thing you need to know is where fish hide in streams and rivers. Undercut banks, eddies, sunken trees, rocks and overhanging trees and bushes provide protection from the current and above-water predators (such as birds).
Do fish live in the river?
Rivers are home to abundant fish and wildlife, including: Freshwater fish like bass, perch, bluegill, and catfish. Migratory fish such as alewife, salmon, trout, and striped bass. Invertebrates that provide food for fish.
Where do most fish live?
Fishes live in virtually all aquatic habitats. Different species of fish are adapted for different habitats: rocky shores, coral reefs, kelp forests, rivers and streams, lakes and ponds, under sea ice, the deep sea, and other environments of fresh, salt, and brackish water.
What fish live in rivers?
Most ponds, reservoirs, and rivers across North America are freshwater. Some common freshwater fish are bluegills, carp, catfish, crappie, bass, perch, northern pike, trout, and walleye.
Where do those fish live?
About half of fishes live in freshwater terrestrial environments such as lakes and streams while the other half live in the oceans. The physiological cost of dealing with differences between saltwater and freshwater is so great that few fishes can tolerate both.
How does fish live in water?
All fish have gills that allow them to breathe water. Just like we use our lungs to exchange oxygen for carbon dioxide from the air, the gills of a fish perform a similar function from water. So fish still need oxygen to live, they just get it from the water instead of the air.
Where do fish go in the winter in rivers?
Trout and other stream fish prefer to spend winter in habitats with large deep pools and boulders and survive well under stationary ice. Groundwater inputs provide access to warm water and can support aggregations of larger fish.
Which fish live in lakes and rivers?
Tilapia are freshwater fish that live in shallow water, rivers, and lakes, although they can also be found in brackish water in India. Tilapia is also one of the most popular fish in the world and, after carp and salmon, one of the most important species in aquaculture.
Do all fish live in water?
Fish live in nearly every large body of water in the world including streams, rivers, ponds, lakes, and oceans. Some fish live on the surface of the water and some live in the very depths of the ocean. There are fish that live in fresh water and others that live in salt water.

Are fish everywhere in the ocean?
The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of 4000 metres.

How would you describe a fish in a river?
Slippery, scaly, luminescent, shiny, delicious, crispy, golden, juicy, battered, smelly, salty, slimy, foul-smelling, wet, water-dwelling, iridescent, white-bellied, gullible, fickle, curious, finned, bony.
What fish live in a lake?
Some of the most common fish found in lakes are tiny shiners, sunfish, perch, bass, crappie, muskie, walleye, perch, lake trout, pike, eels, catfish, salmon, and sturgeon. Many of these provide food for people. Lakes are an important part of the water cycle; they are where all the water in an area collects.
Where can you find fish in the ocean?
Ocean Fishing
Put simply, you want to find cover, depth change, and currents. Rocky areas in bays are ideal because they provide all three of these key factors. Scan the water in your chosen area for disrupted water – a sign of schools of bait fish, as well as birds sticking close to one specific area of the water.
Where do fish hide in the ocean?
In coastal areas, closer to shore, the ocean bottom most covered with sand but may also have sections of exposed rock. Fish live at all depths in coastal water, but most stay close to the bottom. Many feed near cover, such as a rock or a coral reef, where they can ambush prey.
Where do fish come from?
Of the ~90 million tons of captured fish consumed around the world, roughly 80 million tons come from the ocean. The other 10 million tons come from freshwater lakes and rivers, mostly in Asia and Africa.
Why does fishes survive in water?
Just like all animals, fish needs oxygen to survive. They have gills as their respiratory organs. These gills can take oxygen only from water and not air. Hence it is necessary for them to live in water.
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart.
Can a fish drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen. Fishing equipment, such as some types of hooks, can damage the gills.
How do fish get into rivers?
Over longer time periods, movement of fish between basins is often facilitated by “headwater capture.” This is when a river tributary cutting its way upstream toward the divide between basins causes enough erosion to cut through that divide, thus serving as a waterway between two rivers.
Can a fish freeze to death?
As the anoxic zone creeps upwards into the water column, fish cling to the under-surface of the ice as the oxygen is depleted, until they suffocate to death.
Do fish get thirsty?
They don’t ever get thirsty. Marine fish are what’s called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.
