Associated characteristics


Species Development state Trait Primary Data Secondary Data
Salvelinus fontinalis Female Length at sexual maturity Means of female sizes involved in spawing range from 36.5 ±1.2 to 41.1 ± 1.3 36.5 cm
Salvelinus fontinalis Male Length at sexual maturity Means of male sizes involved in spawing range from 37.5 ±2.0 to 42.4 ± 1.2 37.5 cm
Salvelinus fontinalis Spawning conditions Mating system For males and females, tha mating costs of peripheral males were substantial because more than half (56%) of all observed brrok trout spawnings involved peripheral males. Males that paired with large females experienced a greater incidence of kleptogamy due to increase numbers of peripheral males present No category
