They have developed a substantial body of theory that has been applied successfully to a large number of animal populations and has led to a major improvement in the management of some of the ma jor marine fisheries. The theory has been developed for single species populations with man as a predator. Much of it is based on the Darwinian concept of a constant overpopulation of young that is reduced by density dependent mortality resulting form intraspecific competition. The unfished population tends toward a maximum equilibrium size with a relatively high proportion of large, old individuals. As fishing increased and natural mortality is reduced, death from fishin eventually takes the place of most natural mortality. If the amount of fishing is increased too much, the indivduals will tend to be taken before realizing their potential growth, and total yield will be reduced. The maximum sustainable yields can be taken at an intermediate population size that in some populations is about one third the unfished population size G V Nikolskii, of Moscow State University, develops his theory from a different approach. He is non Darwinian and is(he says)a nonmathematician; rather he considers himself as ecologist and morphologist. He argues that Darwins s concept of constant overpopulation has led to the eglect of the problem of protecting spawns and young fish. He argues also that Darwin s concept of a variety as an incipient species have led to extensive mathematical analysis of racial characters. Nikolskii considers the main laws of population dynamics to be concerned with the succession of generations; their birth, growth, and death. The details are governed by the relative rates of adaptaton and environmental change. The mass and age structure of a population are the result of adaptation to the food supply.
