The aim of this study was to identify and assessthe growth
retardation observed with increasing temperatures and led to
economic losses at a rainbow trout (Oncorhynchus mykiss)
farm at the Karaova Dam Lake within the province of Kirsehir,
and to perform a poisson regression analysis and estimation
on the effect of temperature. During the study, fish
demonstrating signs of growth retardation were identified.
For the studied rainbow trout, the value of the Pearson
statistic was determined as 9.14, the deviation statistic as
7.53, and the artificial R2 as 78.15, and the Chi-squared
goodness of fit as 21.11.Based on the poissonregression
analysis, it was determined that temperature levels had an
adverse effect on fish growth.
