Developmental trait (?) | Spawning References: FishBase (2001) Salvelinus fontinalis Brook trout. Comments: Spawning occurs in shallow riffles or shoreline with loose gravel and oxygen-rich water during late summer or autumn depending on the climate. Males court females by driving them towards suitable spawning gravel. Receptive females dig a depression, or 'redd', in the gravel bed. Males swim around the female, over and under her, while she digs. He rubs her with his fins and fends off other males. The pair enter the redd and the female deposits the eggs while the male fertilizes them. The female then covers the eggs with small gravel and sediment |

Known economic impact? | Known References: Roberts, J. 2000. "Salvelinus fontinalis" (On-line), Animal Diversity Web. Accessed July 19, 2024 at https://animaldiversity.org/accounts/Salvelinus_fontinalis/ Comments: Brook trout and their vastly popular sport fishing bring to a community related recreational activities such as camping, boating, and the need for gear, guides and transportation, all of which provide positive economic opportunities. |
Known measurable environmental impact? | Known References: Bechara, J. A., Planas, D., Paquet, S. 2007. Indirect effects of brook trout (Salvelinus fontinalis) on the structure of epilithic algal communities in an oligotrophic boreal forest stream. Fundamental and applied limnology, 169(2), 89. Comments: In spite of not being herbivorous, brook trout can also affect periphyton community structure by bioturbation of the substrate when swimming close to the bottom, by chasing invertebrates hidden among algal mats, or even by releasing nutrients that enhance algal growth, such as in some lacustrine food chains. |
