Tribes and local conservation teams are finding ways to protect walleye and the spearing tradition.

部落和当地的保护团队正在寻找保护角鱼和鱼叉捕鱼传统的方法。

But the number of walleye fish in the lake is decreasing due to warming waters, seasonal changes and lake development.

但是，由于水温升高、季节变化和泊开发，中角鱼的数量正在减少。

In 2022, Wisconsin's Department of Natural Resources updated its conservation plan for walleye, with a focus on climate change.

2022年，威斯康星州自部更新了其针对角鱼的保护计划，重点关注气候变化。

Wolter said, " It's not that the adult walleye are just dying out, it's that the amount of reproduction isn't happening at the same levels that it used to, especially in certain water bodies."

“并不是说成年大眼梭鲈正在灭绝，而是繁殖数量没有达到过去的水平，特别是在某些水体中。”
