Abstract
Abstract Conserving genetic diversity within and among populations of northern pike Esox lucius is important for maintaining their short-term fitness and long-term evolutionary potential. Northern pike have consistently shown low within-population variation, as detected by allozymes, mitochondrial DNA, and randomly amplified polymorphic DNA. Microsatellite DNA loci reveal considerably greater variation in northern pike, yet microsatellite variation tends to be less than that in other fish species. Low genetic variation within populations may result from compounding factors of low effective population size and bottlenecks. Allozyme, randomly amplified polymorphic DNA, and microsatellite markers have revealed significant differentiation of populations located in different continents and major drainages, but only microsatellites have differentiated populations on finer geographic scales. Within the north-central United States, analyses with microsatellites have detected genetic differences among most populat...
