Abstract Outside its native range in Alaska, the northern pike (Esox lucius) is a destructive aquatic nuisance species (ANS). Pike are native north and west of the Alaska Range, but they do not naturally occur in Southcentral Alaska or in most Southeast watersheds. Most of the ecologically and economically important salmonid production in Alaska occurs in these locations. The proliferation of pike within these areas has become a fishery management concern because pike are voracious predators and prey heavily on juvenile salmonids. Outside its native range, pike have the potential to interfere with ecosystem function and destroy economically important fisheries. Due to illegal introductions and subsequent dispersal, pike are found in several Cook Inlet watersheds including the Susitna River Basin, the Anchorage Area, and watersheds on the Kenai Peninsula. Pike have also been illegally introduced to ponds within the city of Yakutat in Southeast. Pike have been problematic in other states as well as in Alaska, and several state agencies are trying to control or eradicate them. In Alaska, fishing regulations for pike have been liberalized in hopes that angling pressure will reduce introduced populations. In addition, netting programs have been implemented to document water bodies with pike and, in some cases, reduce their abundance. Though control netting is a good start, it is clear that more efficient control methods are necessary. Alaska Department of Fish and Game (ADF&G) plans to implement extensive public outreach programs to inform the public about the consequences of illegal pike introductions to both prevent further illegal introductions and gain public support for control actions. The specific objectives of this management plan are to: 1. Increase public awareness of problems associated with invasive pike. 2. Prevent future pike introductions and re-introductions to restored areas. 3. Initiate public processes to gain support for management actions. 4. Implement scientifically sound management options to control or eradicate pike. 5. Improve wild salmon and resident fish populations that have been impacted by pike. 6. Restore enhanced fisheries that have been reduced or eliminated by pike.
