چکیده
The aim of this study was to determine the relationship between RNA and DNA concentrations in body tissue and the condition factor in the catfish, Heteropneustes fossilis. RNA was related curvilinearly to condition, while DNA maintained a reciprocal relation. The biochemical basis of changes in condition and the effect of these changes on tissue specific gravity have been discussed and the relationships determined.
