Rainbow/Brown Trout When the water temperature hits 68 degrees, both species will begin to get stressed. If the water temperature continues to rise and gets in the 75 to 77 degree range for an extended period, it can be lethal for Rainbow and Brown Trout.
What is the warmest water rainbow trout can live in?
As temperature rises and dissolved oxygen decreases, fish begin to experience stress. These stresses begin to set in well before the water temperature reaches lethal limits. For example, rainbow trout are said to be able to survive in temperatures up to and exceeding 77°F (24°C), but stop growing at 73°F (23° C).
What temp is too hot to fish?
So how hot is too hot? Coldwater fish such as trout, steelhead and salmon will start to feel stressed when water temperatures hit 68°F. Warmwater fish can tolerate temperatures up to 86°F, but they’ll probably be sluggish and slow to bite.
Is rainbow trout a cold water fish?
Rainbow trout is an anadromous, cool- to cold-water fish species. Although rainbows have been known to tolerate higher temperatures, they do best in areas where the water remains below 70°F. Eggs are laid in shallow nests dug out by the female in gravel riffles.
How hot is too hot for trout?
As an ethical angler, you’ll want to know how hot is too hot for trout fishing. Because of these compound effects, a rule of thumb is to avoid fishing when water temperatures are above 68-70°F.
How old is a 20 inch rainbow trout?
In less than two years, these farmed rainbow trout can reach a length of 20 or more inches and weigh around 6 to 8lb.
Do trout like warm water?
Prime trout feeding water temperatures are between 45 and 65 degrees Fahrenheit. Any warmer and you run the risk of playing a fish to exhaustion. Any colder and those trout will become lock-jawed as they do their best to conserve energy.
Why do trout need cold water?
For the trout, temperature tolerance is about more than comfort. Colder water holds more oxygen. As the water warms, dissolved oxygen begins to dissipate causing trout to feel stressed well before low oxygen reaches lethal levels.
Is it bad to fish when it’s hot?
Fish become heat-stressed and don’t hit your lure quite as often as the water heats up. Just like humans, fish can get testy and cranky when they’re overheated. You don’t necessarily have to give fishing up for the season after a slew of hot days.
What type of water do rainbow trout live in?
freshwater streams
All rainbow trout and steelhead occupy freshwater streams or lakes at some point in their lives. They use aquatic vegetation, boulders, and wood as protective cover. Steelhead spend the majority of the year in estuaries or open ocean and only return to freshwater to spawn.
What depth do rainbow trout swim at?
from the surface. During the warmer months, Trout are at-least 15 ft. deep and can even get down to 160 ft. Advanced trolling equipment and techniques are required to target these deeper areas.
What is the lifespan of a rainbow trout?
Life Span and Reproduction
Maturation begins as early as one year with average survival of three to four years. Maximum known longevity is 11 years but 7 year olds are typically the oldest in most populations.
Do trout like cold or warm water?
Trout are most actively feeding in comfortable water temperatures between 34 and 67 degrees Fahrenheit. Trout feeding picks up just as the water temperature rises one degree above 40, 45 and 49 degrees Fahrenheit, so taking the water temperature every hour is beneficial.
What temp do trout stop biting?
A sound principle of trout fishing is, when the water temperature drops one degree between 45 and 65 degrees trout shut down. They either never start feeding; or if they were feeding, they suddenly quit.
What kind of water do trout like?
The shallow, highly oxygenated water is a perfect environment for the aquatic insects trout eat. Boulders and rocks create plentiful hiding and resting spots. Deeper water downstream gives trout rest and security. All of these aspects make a riffle a great starting point when looking for trout.
What is the biggest rainbow trout ever caught?
48 pounds
Rainbow Trout: 48 pounds

How many hearts do trout have?
two hearts
That is, trout actually have two hearts. The first functions as the normal blood-pumping machine and, in most fish, sits right behind the throat. This four-chambered heart pumps deoxygenated blood to the gills where it fills small capillaries.
What is the biggest trout ever caught?
The world record brook trout record has stood for over 100 years! The current record is 14 pounds and was caught in the Nipigon River in Ontario, Canada.
How deep of water do trout need to survive?
According to the Fishbase online database Rainbow trout inhabit water between 0 and 200m (656ft). The source of this maximum depth is from the Catalog of marine and freshwater fishes of the northern part of the Sea of Okhotsk. Vladivostok: Dalnauka, 2003.

What is the best time of day for trout fishing? The best time of day to catch trout is early morning from dawn until 2 hours after sunrise and the second-best time of day is late afternoon from 3 hours prior to sunset until dusk.
How do you catch trout in hot water?
Look for the dark pockets of water on streams. They may only be 2 feet deep and 8 feet long, but they hold fish. Slow down. Except for extreme feeding sprees, trout may feed infrequently during daylight hours, the time when most summertime anglers hit the streams.
