摘要: SUMMARY Evolution of body and yolk weights brown trout (Salmo trutta L.) alevins was studied during 91 days following fertilization. The were reared under a mean temperature 8,8°C (range : 3,8°C-12,3°C). They either fed from the opening oesophagus or fasted. This study shows that resorption can be described, fertilization, by means theoretical model, which takes into account weight fasted alevins. No difference in between detected. Before complete resorption, significantly higher than Consequently, early feeding should recommended to reduce period alevin stage.
