| Abstract: | To study the effect of morphometric attributes on body weight of the Steelhead Oncorhynchus mykiss,morphometric measurement was taken from 116 samples.The attributes used in this study include body length,body height,body depth,head length,eye diameter,eye cross and bodyweight.A correlation coefficient matrix was constructed,in which the body weight was used as the dependent variable and other attributes as independent variables for path analysis.The path coefficients,determination coefficients,and correlat... |
