** (.):** We study several models of fishery control with catch quotas. Alternative linear approximations of initial non-linear problems are suggested along with linearized routines for their study. We also suggest game-theoretic models of fishery and consider illustrative examples for optimal quota assignment problem and for the maximal profit problem.
