Title: Энергетический баланс морского ежа Strongylocentrotus droebachiensis (O. F. Muller), использующего разные формы пищи Authors: Холодов В. И. Abstract: An extended energy balance of Strongylocentrotus droebachiensis is studied. It is established that divergence in the energy balance observed in the experiment is mainly due to discrepancy in the ration volumes in the experiment and under nature conditions as well as taking no account of organic matter in a soluble form. By the method of the main components it is determined that 99% of total variation in the energy balance is caused by the following: changes in the balance parameters in the process of ontogeny peculiarities of the plastic metabolism, variability in the body mass of the animal at a definite age, physiological peculiarities of Strongylocentrotus droebachiensis (O. F. Muller) maturing. The mathematic modelling of growth established that a noticeable growth of Strongylocentrotus droebachiensis is observed up to the age of 8 - 8.5. The size-frequency analysis of the natural population permits detecting the age classes not older than 8-9.
