  2. Von Bertalanffy function - Wikipedia

    en.wikipedia.org/wiki/Von_Bertalanffy_function

    The von Bertalanffy growth function (VBGF), or von Bertalanffy curve, is a type of growth curve for a time series and is named after Ludwig von Bertalanffy. It is a special case of the generalised logistic function. The growth curve is used to model mean length from age in animals. [1]

    The Bertalanffy equation describes the growth of a biological organism. It was presented by Ludwig von Bertalanffy in 1969. [11] = Here W is organism weight, t is the time, S is the area of organism surface, and V is a physical volume of the organism.

    The individual growth model, published by von Bertalanffy in 1934, can be used to model the rate at which fish grow. It exists in a number of versions, but in its simplest form it is expressed as a differential equation of length ( L ) over time ( t ): L ′ ( t ) = r B ( L ∞ − L ( t ) ) {\displaystyle L'(t)=r_{B}\left(L_{\infty }-L(t ...

    It assumes that there is a relationship between size and natural mortality. Pauly’s original method was based on the correlation of M with von Bertalanffy growth parameters (K and L∞) and temperature (Gunderson 2002): N0 = N 1*e(-Z*∆t)

    Biochemical systems theory is a mathematical modelling framework for biochemical systems, based on ordinary differential equations (ODE), in which biochemical processes are represented using power-law expansions in the variables of the system.
