A Differential Game Model of Canada′s Pacific Halibut Fishery

Models Canada′s Pacific halibut fishery as a non‐zero‐sun on‐co‐operative differential game. Optimal harvesting level are derived under the criterion of profit maximization. Show that optimal aggregate steady‐state fishing effort and yield increase with the number of fishermen harvesting the stock. The model provides a better explanation of what has actual occurred in this fishery than an optimal control model, which may be considered as a game with one player.
