Changes in population structure of two coregonid species (Coregonus lavaretus L. and C. peled Gmel.) kept in illuminated cages from hatching until maturity are a result of concerted action of a number of ecological factors, food resources playing the key role. The analysis of long-term trends in body size variability and in changes within each stock allows to reconstruct the conditions of growth in cages and to indicate certain critical periods in fish life.
