| Species | Development state | Trait | Primary Data | Secondary Data |
| Salvelinus fontinalis | Female | Length at sexual maturity | Spawning females were: in 1994, n=47, 37.2 ±6.5; in 1995, n=42, 37.6 ± 6.4 | 37.2 cm |
| Salvelinus fontinalis | Female | Weight at sexual maturity | Spawning females were: in 1994, n=45, 656 ±395 g; in 1995, n=42, 705 ± 381 g | 656.0 kg |
| Salvelinus fontinalis | Male | Length at sexual maturity | Spawning females were: in 1994, n=50, 33.4 ±7.7; in 1995, n=65, 33.7 ± 6.5 | 33.4 cm |
| Salvelinus fontinalis | Male | Weight at sexual maturity | Spawning females were: in 1994, n=48, 480 ±407 g; in 1995, n=63, 507 ± 351 g | 480.0 kg |
| Salvelinus fontinalis | Spawning conditions | Spawning season | Brook trout were observed on or near the spanwing grounds over a 64-d period in 1994 (30 September to 2 December) and a 61-d period in 1995 (25 September to 24 November) | ['September', 'November', 'December'] |
| Salvelinus fontinalis | Spawning conditions | Spawning period duration | 3-4: The seasonal peak in spawning activity: 1994, days 296-310; 1995, days 296-312 coincided with peak counts of males and females [Brook trout were observed on or near the spanwing grounds over a 64-d period in 1994 (30 September to 2 December) and a 61-d period in 1995 (25 September to 24 November). Peak number of males and females occurred approximatively the same time, between 22 Ocotber to 8 November. The duration of time spent on the spawning grounds was longer for males in 1994 than in 1995 (31 ± 12 and 22 ± 9 d, respectively), although no difference was observed for females between years (11 ± 6 and 15 ± 7, respectively).] | 31.0 weeks |
| Salvelinus fontinalis | Spawning conditions | Spawning temperature | During peak spawning periods, water temperature in the spawning area decreased from 11.3 to 8.8°C in 1994 and from 10.3 to 5.9°C in 1995 | 11.3 °C |
| Salvelinus fontinalis | Spawning conditions | Spawning depth | Redds were located in the shallow littoral zone (1994, 1± 0.4 m; 1995, 1.6 ± 0.5 m) and near shore | 1.0 m |
| Salvelinus fontinalis | Spawning conditions | Nycthemeral period of oviposition | We observed spawning at all times of the day throughout both seasons, with a distinct peak in activity between 13:00 and 14:00. Eighthy-nine percent of all spawning toook place during the hours of daily observation (09:00-18:00), the remaining spawnings occurred either just prior to our arrival (3%) or sometime after our departure (8%) | Day |
