Yamagishi, H., Ishioka, K., & Matsumoto, T. (1988). Simulation Study on the Growth Variation of Fish with Special reference to the Exponential and Aymptotic Growth.
Zusammenfassung: Computer simulation of fish growth was conducted in order to clarify the mechanism of individual variation in terms of coefficient of variation (CV) and skewness of frequency distribution (sk). Normal distributions of initial body length, specific growth rate (growth coefficient) and asymptotic value were supposed. In exponential growth accompanied by the changes of distribution of body length from normal to lognormal, both CV and sk continuously increased.

Yamagishi, H., & Ishioka, K. (1989). Simulation study on the growth variation of fish with special reference to the sexual dimorphism in growth.
Zusammenfassung: With respect to the sexual dimorphism in growth of fish, computer simulation of individual growth variation was made in terms of coefficient of variation (CV) and skewness (sk) of frequency distribution. Normal distributions of initial body length, specific growth rate in exponential growth coefficient in asymptotic growth and asymptotic value (each consisting of 500 monosexual distributions) were supposed. In exponential growth both CV and sk of the bisexual distributions increased more quickly than the two monosexual distributions. In asymptotic growth (Bertalanffy and Logistic) CV of the bisexual distribution was always greater than the monosexual distributions, and sk of the former was greater in positive value and smaller in negative value than those of the latter all the time.

Yamagishi, H., & Ishioka, K. (1991). Silumation Study on the Growth Variation of Fish with Special Reference to the Mortality by Cannibalism.
Zusammenfassung: In respect to the higher initial mortality in fish by cannibalism, computer simulation of individual growth variation was made in terms of coefficient of variation(CV) and skewness(sk) of frequency distribution. CV of the cannibalistic groups changed similarly to the control groups, but converged on smaller values than the asymptotic CV of the control groups. Sk of the cannibalistic groups finally converged on similar values to those of the control groups after irregular changes in positive values except N-N correspondent type.
