This historical essay describes the theory behind, and implications of, models of optimum yield from an exploited animal population (in particular for whaling) formulated by Johan Hjort and his colleagues, Per Ottestad and Gunnar Jahn, in the 1930s. The essay places the evolution of fishery science during the 1930s–1940s into context.
