References (not structured): Scott WB, Crossman EJ, 1973. Freshwater Fishes of Canada. Bulletin 184, NO. 184:966 pp. Comments: The species preferentially occupies the nearshore (littoral) area of lakes due to the abundance of aquatic vegetation and warm temperatures. |

Developmental trait (?) | Spawning References: Scott WB, Crossman EJ, 1973. Freshwater Fishes of Canada. Bulletin 184, NO. 184:966 pp. Comments: Spawning occurs in late spring to mid-summer in Canada, when water temperatures reach 15.6 °C. Spawning sites consist of sand, gravel or marl substrates and are usually contained within protected waters (coves, bays of larger lakes) with ample aquatic vegetation. Males clear a 61-95 cm area that may include exposed roots of emergent vegetation. Nudging and nipping between male and female initiates spawning, which results in the female depositing between 2000 and 109,314 eggs that are 1.5-1.7 mm in diameter. Males aggressively guard the nest during egg development. Hatching takes 3-5 days in southern Ontario, which produced transparent fry about 3 mm long. A nest may produce between 751-11,457 fry, averaging 5000-7000 individuals. |
Characteristic feeding method / Life stage (?) |
References (not structured): Scott WB, Crossman EJ, 1973. Freshwater Fishes of Canada. Bulletin 184, NO. 184:966 pp. Comments: M. salmoides are a generalist carnivore, feeding mostly during the day and eating mainly nearshore organisms that occur frequently within freshwaters. Their diet consists mostly of invertebrates at young ages, but will be dominated by fishes as age increases. Cannibalism may occur, especially in age-0 individuals exhibiting high variability in growth rate |
