Formicki, K. and Sadowski, J. and Tanski, A. and Korzelecka-Orkisz, A. and Winnicki, A. (2004) Behaviour of trout (Salmo trutta L.) larvae and fry in a constant magnetic field. J. Appl. Ichthyol., pp. 290-294
| Species | Development state | Trait | Primary Data | Secondary Data |
| Salmo trutta fario | Larvae | Larvae behaviour | From hatch until two-thirds of the yolk sac was resorbed; this time intervalwas deliberately selected because from hatch until two-thirds of the yolk sac has been resorbed, the trout larvae, or -strickly speaking-, eleutherembryo, excessevely weighted by the yolk sac, stays immobile and close to the bottom and performs only slight movement in the water column | Demersal |
| Salmo trutta fario | Larvae | Onset of exogeneous feeding | Freely swimming fry, a few days after the yolk had been completely resorbed; the fry had already strated actively feeding and were behaving as fully formed organisms. The fry measured 25-35 mm | 30.0 °C * day |
