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 |
