Ivlev, V. S.2023-05-302023-05-301960On the utilization of food by planktophage fishes / V. S. Ivlev // Bulletin of Mathematical Biophysics. –– 1960. –– Vol. 22. –– P. 371–389.https://repository.marine-research.ru/handle/299011/12529Making some plausible assumptions about the over-all mechanism of food catching and consumption by fishes and evaluating in the light of those assumptions some available experimental data, it is possible to calculate from those data the variation of several important factors with the concentration of food. The factors considered are: total rate of metabolism, total diurnal energy expenditure in the process of feeding, average number of hours per day during which the fish feeds, average length of path traveled by a fish per day, and the so-called “energetic coefficient of growth.” A possible relation with the work of N. Rashevsky (Bull. Math. Biophysics,20, 299–308, 1959) is discussed.en
