Abstract
This study has been conducted to find out fecundity of
rainbow trout raised at Gip Research station of Fisheries School, Fırat University. Thirty four fully matured female trouts of three and lour years of age
were used. Estimates of ova were made both volumetrically, gravimetrically and
by actual count. The calculation of egg number per female fish, per kilogram
and cubic centimeter of eggs per kilogram of fish were made. Eggs didmeter
were also measured. .
The mean number of eggs per female of threeyears old was 2988, for four
,)'ear old was 3228. Number of eggs per kilogram ~ffish were 3926 for three
years old, 2092 for four years old group. Relative fecundity, that is the number
number of eggs per kilogram of body weight of the female, was 3009 eggs on the overall average. The relative fecundity did not markedly change in relation
to body lengtk.
Diameter if matured eggs varied between 4.1 and 5.1 mm. in three years
of age and 4.7-5.2 mm. in four years if age being positively correlated with
the body lengtk if female.
