Chelatna pike suppression in 2018 and 2019

Northern pike are an invasive species in southcentral Alaska and have
caused the decline and extirpation of salmonids and other native fish
populations across the region. Over the last decade, adaptive management
of invasive pike populations has included population suppression,
eradication, outreach, angler engagement, and research to mitigate damages
from pike where feasible. Pike suppression efforts have been focused in
open drainages of the northern and western Cook Inlet areas, and
eradication efforts have been primarily focused on the Kenai Peninsula and
the municipality of Anchorage. Between 2010 and 2020, almost 40,000 pike
were removed from southcentral Alaska waters as a result of suppression
programs, and pike have been successfully eradicated from over 20 lakes
and creeks from the Kenai Peninsula and Anchorage, nearly completing total
eradication of pike from known distributions in those areas. Northern pike
control actions are tailored to the unique conditions of waters
prioritized for their management, and all efforts support the goal of
preventing further spread of this invasive aquatic apex predator to
vulnerable waters.

白斑狗鱼（Northern pike）是阿拉斯加中南部的入侵物种，已导致该区域鲑科鱼类及其他本土鱼类种群的衰退与灭绝。过去十年间，针对入侵白斑狗鱼种群的适应性管理措施包括种群抑制、根除、宣传推广、垂钓者参与，以及在可行区域开展减轻狗鱼损害的研究。狗鱼抑制工作主要集中在库克湾（Cook Inlet）北部及西部的开放排水区域，而根除工作则重点针对基奈半岛（Kenai Peninsula）和安克雷奇市（municipality of Anchorage）。2010至2020年间，通过抑制项目从阿拉斯加中南部水域移除了近40000条狗鱼；同时，基奈半岛和安克雷奇的20多个湖泊与溪流已成功根除狗鱼，几乎完成了这些区域已知分布区内狗鱼的全面清除。白斑狗鱼防控行动会根据优先管理水域的独特条件量身定制，所有努力均旨在防止这一入侵性水生顶级捕食者进一步扩散至脆弱水域。
