Рост и энергетический бюджет плоской устрицы (ostrea edulis) в раннем онтогенезе
Growth and the energy budget of flat oyster (Ostrea edulis) in early ontogenesis

Summary/Abstract: Regularities of growth and dynamics of balance constituents of the energy budget of the flat oyster larvae in development are investigated. It is shown, that the linear growth in early ontogenesis is described by the exponential equation with high accuracy. Parameters of the functions connecting length, height and weight of larvae are defined. The quantitative characteristic of the energy balance elements of oysters larvae is given. It is shown, that during development from a veliger stage to a pediveliger the energy expenditures for growth, metabolism and nutriment assimilation increase more than 10 times. Net efficiency of larvae growth (coefficient К2) varies within 61.6–62.8 % during development, and the magnitude of a specific daily ration of oyster larvae equals 32–35 % of the energy equivalent of body weight.
