Abstract

In order to illustrate the origin of occurrence of congenital malformation in RAINBOW TROUT, in the present study, the percent and type of malformation in brother-sister mating were compared with those of control. For this propose two pair of breeders from different stocks have crossed to produce sister-brother line. For estimation of mean deviation between family and non FAMILY MATING of traits, analysis of variance have used and hatchability rate was lower in FAMILY MATING but was not significantly different (p<0.987). In this study the type and percent of abnormal larvae, fingerling and marketable size fish were investigated. Pug head, curved body, shortened tail and enlargement of the yolk sac was the character of malformations at larval stage. The difference of mean at the end of yolk absorption and ABNORMALITY at stages of 150, 225 and 300 days have not shown any significant difference (p<0.960, p<0.774, p<0.775, p<0.730) respectively. The fingerling of 450 mg, one month after active feeding stages, had only 5% abnormal consistent of shortened body length (92%), pug head (2%), shortened operculum (5%) and lump back(1%). It was shown that even in crossing between close family (sister-brother), the ABNORMALITY was not significantly higher than normal mating, therefore it may be due to environmental factors of management problems.
