A formula to determine the efficiency of food conversion to fish body growth was examined, in order to advance the formulae on the growth of fish, which had been showed in the previous paper³⁾. As results of the experiments, the following formulae and others were obtained.
The formula on the relation between efficiency of conversion (X) and body weight (W) is:
X=^β/_δβ'-^γ/_δβ'W¹³
The formula on the relation between the rate of increase in weight (Y) and the rate of food uptake (Z) is:
Y=^β/_δβ'Z-^γ/_δ
δ is the energy per unit weight used for construction of the increased portion of body, and δ, β', β, and γ are constants.
