Brook Trout Reproduction and Lifespan Brook Trout will spawn in the fall, from October to early November. The female will create a shallow, “redd” nest in a clean area with small gravel or stones. She will lay around 100-400 eggs, and multiple males will fertilize the eggs. The femal...
Hatchery-reared wild and domestic strains of brook trout (Salvelinus fontinalis) were released in natural lakes, and survival and growth estimated at semiannual intervals throughout the life span. Angling was restricted. Four experiments with two year-classes involved three different Adirondack Mountain ...
Fig. 1. Mean CTmax (°C) for brook trout (Salvelinus fontinalis) life stages incubated under varying winter thermal regimes as embryos. Error bars represent standard deviation (s.d.). Thermal tolerance of age 2+ adult treatment groups did not differ based on the temperature treatment in which...

We hypothesized that the spatial distribution of groundwater inflows through river bottom sediments is a critical factor associated with the distribution of coaster brook trout (a life history variant of Salvelinus fontinalis) spawning redds. An 80-m reach of the Salmon Trout River, in the Huron ...

Summary 1. Species with distributions that span a broad range of latitudes may have populations that exhibit distinct life history traits associated with environmental gradients. The majority of previous studies have indicated a strong association between spawning site selection by brook trout (Salvelinus...
