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
