Moreover, the fish will not have had a chance to reproduce, undermining the fish stock altogether. For example, the avowed intention of the EU Common Fisheries Policy is "to protect fish resources by regulating the amount of fish taken from the sea, by allowing young fish to reproduce , and by ensuring that measures are respected."
渔业政策旨在保护幼苗得以生长。原因不证自明：捕捞幼鱼会导致重量上大幅减产；而且鱼群也将因此失去繁殖机会，招致鱼类总储备量下降。例如， 欧盟共同渔业政策就是"通过调节海上捕捞数量、允许鱼苗繁殖和保证此类政策被切实执行来保护渔源"。
