Research of seasonal, sexual and species differences of white muscle bioenergetic state of cod and plaice

In the paper the analysis of seasonal dynamics of adenine nucleotides in north fish white muscle has been given. The authors have compared energy metabolism of Gadus morhua morhua L. and Pleuronectes platessa (L.). of the same age. The results have shown that the quantity of macroergic compounds depends on life's stage, the sex (male or female), and different environmental factors. It has been established that there is more ATP in the muscle tissues of more active cod.
