Characteristics of a healthy fish population include its ability to produce numerous healthy, fecund, and normal-sized adults and to resist or rebound from short-term stresses. These characteristics generally can be expressed in terms of the population staying within a certain range of values in abundance, age structure, length and weight structure, condition factor, and sex ratio. The individual-based modeling approach is an alternative to traditional models that permits explicit representation of the feedback between the differing physiological states of individual members of the population and their ability to feed, grow, reproduce, and avoid disease and predation. -from Authors
