Net Gain

Skipper a herring trawler in the North Sea for ten years. Steer through the shoals, shoot your net and haul in the catch. With no rules and more boats every year, the herring stock crashes. Then bring in licences, limits on boat size, a bigger mesh size, a closed season, a quota, a Marine Protected Area and an international agreement, one a year, and watch the stock and the wildlife come back.
