Salmon require cold, clean, oxygenated water to survive. If the water's too cold, development will slow and the aquarium may even freeze.
The ideal temperature for salmon to thrive is between 40ËšF to 50ËšF, when water is warmer than the usual temperature it is physiologically unsuitable for salmon. Warm water temperature increases a fish's metabolism burning essential energy at a faster rate.
Cold water has the ability to hold more oxygen than warm water. Hot summer temperatures can heat water so it won't hold enough oxygen to maintain fish life.
When you clean cold water fish there is less blood in the meat because they are need more blood in their internal organs to survive. The end result is cleaner tasting fish
Hot Water Versus Cold WaterFish are sensitive to temperature because they are cold-blooded and can't keep a constant body temperature like humans and other mammals do. Most fish species can't survive in water that is too cold or too hot.
Temperature at which fish become more active (in degrees fahrenheit): Largemouth Bass: 65-75. Smallmouth Bass: 65-70. Rock Bass: 70-74.
As a coldwater fish native to Maine, Landlocked Salmon (Salmo Salar) ideally need water temperatures below 65 degrees Fahrenheit. In the spring, adult salmon tend to populate warmer water and in the summer they group together in glacial lakes with deep water to protect themselves from the heat.
It depends on the species, but in general, tropical fish are most healthy in the range of 75-80°F (24-27°C). Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish.
Warmer Water: The optimum water temperature range for most salmon is 55 to 64 degrees Fahrenheit (12.8 to 17.8 degrees Celsius).
Pike are very specific when it comes to water temperature. Their absolute ideal water temperature is between 64.5F and 70F (18C-21C). This temperature range is ideal for growth and is most comfortable to them. Because of this pike will seek out the warmest areas of the lake while the water is still cold.
August is the month with the highest water temperature at
77.9°F / 25.5°C. The month with the lowest is March with an average water temperature of 32.9°F / 0.5°C.

Atlantic salmon, also known as the “King of Fish,†are anadromous, which means they can live in both fresh and saltwater. Atlantic salmon have a relatively complex life history that begins with spawning and juvenile rearing in rivers.
The salmon run is the time when salmon, which have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds. After spawning, all Pacific salmon and most Atlantic salmon die, and the salmon life cycle starts over again. When they have matured, they return to the rivers to spawn.
Scientists believe that salmon navigate by using the earth's magnetic field like a compass. When they find the river they came from, they start using smell to find their way back to their home stream. They build their 'smell memory-bank' when they start migrating to the ocean as young fish.
The reason, according to a new study, is that they're infested with sea lice—and are trying to splash them off. Researchers already suspected that salmon leap to dislodge sea lice, a pea-size parasite that feeds on mucus, blood, and skin. Jumping out of the water isn't a risk-free proposition for the salmon.
Both the Pacific salmon fish and bamboo only breed once in their lifetime. The Pacific salmon usually breeds in the spring( April, May and June) and after spawning they die.
Salmon are considered “anadromous†which means they live in both fresh and salt water. They are born in freshwater where they spend a few months to a few years (depending on the species) before moving out to the ocean.
All salmon species are carnivores that mostly prey on smaller species of fish and like all predators, they need teeth in order to grab hold of their prey. And prey they do! Of course, their teeth aren't growing at all but are simply being more exposed due to the salmon's ongoing bodily deterioration.
CONCLUSION. A significant body of scientific evidence suggests that yes, fish can feel pain. Their complex nervous systems, as well as how they behave when injured, challenge long-held beliefs that fish can be treated without any real regard for their welfare.
Most salmon species live 2 to 7 years (4 to 5 average). Steelhead trout can live up to about 11 years.
Because the cold reduces a fish's metabolism, they aren't going to go for the big stuff. Because fish aren't as hungry in the cold, attractants will encourage them to bite and hold on once they do.

Warmer waters impact fish in multiple ways. Toxins produced by algae blooms—which are occurring more frequently as temperatures rise—can stress or kill fish by clogging their gills or reducing oxygen levels in the water. Warmer waters also make fish more vulnerable to parasites and diseases.
Different kinds of fish thrive in different water temperatures. In natural habitats, the water temperature affects the way fish grow, reproduce, and feed. Like birds, fish are cold-blooded creatures. But most fish will survive living in slightly warmer temperatures than they require.
For example, lake trout, a cold-water species, can tolerate (survive) temperatures up to 70 to 73 °F but has a core preferred temperature range of 46-59 °F. Smallmouth bass, a warm-water species, can tolerate temperatures up to 86 °F and prefer temperatures above 68 °F.
Fish, like all other complex life forms, need oxygen to survive. Warm water holds less dissolved oxygen than cold water, so summer is the time when fish can have a hard time getting enough oxygen.
