freedom for the pike is death for the minnows meaning
Negative liberty "It follows that a frontier must be drawn between the area of private life and that of public authority. Where it is to be drawn is a matter of argument, indeed of haggling. Men are largely interdependent, and no man's activity is so completely private as never to obstruct the lives of others in any way. 'Freedom for the pike is death for the minnows'; the liberty of some must depend on the restraint of others."[3]
Walleye Walleye (Sander vitreus, synonym Stizostedion vitreum) is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European Zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a subspecies that was once found in the southern Ontario and Quebec regions, but are now presumed extinct.[2] However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification.[3]
