Brook trout enter their spawning season in early September which can continue for some fish through October depending on water conditions. There is typically a 95-100 day egg incubation period. Again, this is also water temperature dependent. After about 100 days, the eggs will begin to hatch and fry will emerge.

What months do brook trout spawn?
Brook trout normally mature in two years but may spawn after one year. These fish spawn between September and October. Brook trout fry will emerge sometime between February and April. Young brook trout normally seek shelter in submerged aquatic vegetation or shallow water near the shoreline.
At what age do trout lay eggs?
In their native watersheds, bull trout migrate into smaller tributaries sometimes as early as July and they begin spawning as early as mid- to late August. Bull trout don't reach sexual maturity until they're at least four years old, and sometimes not until they're seven years old.
How do I know if my trout has eggs?
Look for these indications that there are spawning trout nearby: Redds. Redds are patches of cleaned-off gravel in a stream where trout and salmon lay their eggs. As you can see in the video above, they are usually quite apparent, since they will be a different color than the rest of the stream bed.
Do female trout die after laying eggs?
Unlike salmon, trout don't die after spawning and can participate in spawning multiple times in the course of their life [source: USDA Forest Service]. During a spawning season, a single female rainbow trout can spawn 200 to 8,000 eggs.
Where do brook trout lay their eggs?
During the spawn, the female lays hundreds of eggs and the male fertilizes the eggs. After the spawn, the female brook trout covers the eggs by sweeping pebbles near the downstream portion of the redd.
How many eggs might a female rainbow trout lay every spring?
A single female may lay 400-3,000 eggs depending on her size. The embryos develop for 20-80 days depending on the water temperature. They hatch into what are called alevins (free-swimming embryos with huge yolk sacs) and stay down in the gravel for another 2-3 weeks while their fins develop.
How many eggs brook trout lay?
Spawning occurs in autumn, mainly in late October to early November, during the day. The female uses her tail to create a shallow, 1- to 2-foot-wide nest or “redd” in a clean, gravelly area and lays 100 to 400 eggs into the nest.
How long does it take for a trout to grow full size?
It takes 12 to 14 months for the trout to grow to legal size (7 inches). During this time, trout are fed three to five times per day, and they grow quickly.
How do I know if my trout is pregnant?
A pregnant female trout will often have a prominent ovipositor. What is an ovipositor, you ask? Well, it's simply a fancier term for anus. Most pregnant trout will have a small protrusion on this body part, simply because this is where the eggs will come out when the trout is ready to lay them.
How do you tell a male trout from a female?
Look at the mouth
One of best ways to distinguish the sex of a trout is to examine the mouth. Female trout all have a short rounded nose or upper jaw, while male trout have a more elongated snout. If your trout has a lower jaw with a kype, it's a male for sure.
Do trout turn red when spawning?
As adult trout near spawning maturity, they begin to undergo changes in their color, behavior and anatomy. The trout's exterior shifts from a silvery color to bright red, pink and green. The closer to the spawning event, the easier it is to distinguish between the male and female trout.
Do stocked brook trout reproduce?
Spawning occurs in the fall months, as early as August in the far north to as late as December in the southern portion of their range. ... Very small streams entering lakes can provide important spawning and nursery habitat.
Will brook trout reproduce in a pond?
Brook trout will successfully spawn in a pond if there is some upwelling and a bottom that can be cleaned of detritus down to some gravel. They will most definitely go through the motions. Rainbows and browns need flowing water.
What is the lifespan of a trout?
Life Span and Reproduction
The average life span of wild rainbow trout in Virginia waters is very similar to that of brook trout. 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.
