Developmental rates of embryos of Atlantic salmon, Salmo salar L., in response to various levels of temperature, dissolved oxygen, and water exchange
Embryos of Atlantic salmon. Salmo salur L., were incubated from fertilization to completion of hatching at 5 and 10 °C, at 20, 50, and 100% air-saturation, and at several rates of water exchange from 0.2 to 15 ml/s. Developmental rate to various structural stages, expressed as the reciprocal of time...
