Bascinar, N. and Okumus, I. and Serezli, R. (2003) The development of bràok trout (Salvelinus fontinalis Mitchill, 1814) embryos during the yolk sac period. Turk J Zool, pp. 227-230
| Species | Development state | Trait | Primary Data | Secondary Data |
| Salvelinus fontinalis | Egg | Incubation time | Hatching started on day 55, and 50% hatching occurred on day 58 | 55.0 days |
| Salvelinus fontinalis | Egg | Temperature for incubation | 9.2 ± 1.92 [range 4.5-13°C] | 9.2 °C |
| Salvelinus fontinalis | Egg | Degree-days for incubation | 491 [Hatching started] to 523 [50% hatching] | 491.0 °C * day |
| Salvelinus fontinalis | Larvae | Onset of exogeneous feeding | The first external feeding activities of the fish larvae start when the larvae swim up. Observations have demonstrated that the larva has a piece of yolk when swimming up, so in trout fisheries the first external feeding starts when over 30% of the larvae swim up. | 30.0 °C * day |
