Abstract
A growth curve is an empirical model of the evolution of a quantity over time. Some growth curves for certain biological systems display periods of exponential growth. A Gompertz curve, named after Benjamin Gompertz, is a sigmoid function. It is a type of mathematical model, where growth is slowest at the start and end of a time period. In biology, a growth model is a depiction of length or weight of animals as a function of age. In the case of fish populations, the study of growth is to determine the body size as a function of its age. The growth model developed by von Bertalanffy (1934) has been found to be suitable for the observed growth of most of the fish species. This model expresses length as a function of age of the animal. Fish increases in length as they grow older but their growth rate which is the increment in length per unit time decreases as they grow old.
