We deal with a variational model of the Stock-Recruitment (S-R) relationship in fish dynamic. In this model the S-R relationship is characterized as a minimizer of a suitable integral energy functional. By basic tools of Calculus of Variations a necessary condition is derived. As application, the derived condition is used to test the equilibrium of the recruitment level. An exploratory numerical procedure is also discussed.
