A large fresh-water fish (Esox lucius), found in Europe and America, highly valued as a food fish; -- called also pickerel, gedd, luce, and jack.

highly valued northern freshwater fish with lean flesh

any of several elongate long-snouted freshwater game and food fishes widely distributed in cooler parts of the northern hemisphere

Any of the fishes of the family Esocidæ. Represented in the BWCA by a single, but prominent species, the Northern Pike ( Esox lucius), typically refered to simply as Northern. (The Walleye, sometimes erroneously referred to as "Walleyed Pike" is, in fact, a Perch). The name is short for pike-fish, a reference to the long, pointed snout resembling the pike, an iron tipped staff. Rather like the French, where brochet is the fish, but broche is a spit.

The Pike stream cipher was invented by Ross Anderson to be a "leaner and meaner" version of FISH after he broke FISH in 1994; the name is a humorous allusion to the Pike fish. The cipher combines ideas from A5 with the Lagged Fibonacci generators used in FISH. It is about 10% faster than FISH, yet believed to be much stronger.
