[The correlation between fish growth and several biochemical characteristics by the example of the steelhead Parasalmo mykiss Walb].
Correlation analysis demonstrated a statistically significant correlation of linear-weight characteristics of the steelhead rainbow trout (cultivated steelhead form) with an RNA/DNA ratio and the expression level of the gene encoding cytochrome c oxidase (CO) in two-year-old individuals (1+) as well as the expression level of the gene encoding the myosin heavy chain (MyHC) and activities of the enzymes CO and lactate dehydrogenase (LDH) in muscles and 1-glycerophosphate dehydrogenase (1-GPDH) and glucose-6-phosphate dehydrogenase (G-6-PDH) in the liver of two- and three-year-old individuals (1+ and 2+). With age, the correlation of 1-GPDH and G-6-PDH activities in the rainbow trout liver with the fish body weight increased, whereas their correlations with the body length reduced. The age- and sex-related distinctions in the MyHC gene expression and activities of the white muscle enzyme LDH and the liver enzymes 2-GPDH and G-6-PDH were detected in rainbow trout of both age cohorts.
