Abstract
Transformation of diameters of the rainbow trout eggs in different time, the change of different color eggs before and after absorbing water, number of adopted eggs, fertilized rate and the rate of eyed-eggs were observed and studied in 2001 from August to December and in December, 2002 The results show that there is no relationship between the weight and the egg diameter after analysis of variance, but the egg diameters is related to time and water temperature(r=0 8354, r=0 7634); there are no significant variance between orange eggs and light yellow eggs on the change before and after absorbing water, number of adopted eggs, fertilized rate and the rate of eyed-eggs Quality of orange eggs are better than light yellow eggs
