密歇根州正在推进一项五大湖白鱼人工养殖救援计划，旨在通过从密歇根湖捕捞野生白鱼进行人工繁殖，来保护因欧洲斑马贻贝和魁蚌入侵导致种群数量急剧衰退的白鱼1。该州获得了州预算中的35万美元以及五大湖渔业信托基金近90万美元的资金支持1。计划将从今年秋季开始收集产卵鱼进行遗传救援1。
白鱼种群的危机日益严峻。密歇根湖和休伦湖共有18个独立的白鱼种群，其中大多数处于危险之中1。商业捕获量已从2009年的690万磅下跌至去年的不到200万磅1，而在密歇根湖和休伦湖的部分地区，过去20年间几乎没有幼鱼存活到成年1。Little Traverse Bay Band of Odawa Indians自然资源主管Doug Craven表示，"如果我们今年不做，将来可能没有足够的野生鱼种进行救援"1。
为应对这一危机，密歇根州代表Debbie Dingell和Tim Walberg共同提案，建议在未来十年内投入5亿美元用于贻贝控制研究1。尽管获得初期资金支持，长期资金仍是该救援计划面临的主要障碍1。
Michigan has initiated a genetic rescue program aimed at saving the Great Lakes whitefish population from collapse caused by invasive species.1 The state plans to capture wild whitefish from Lake Michigan for artificial breeding and propagation in response to dramatic population declines driven by European zebra mussels and quagga mussels.1
The initiative has secured substantial funding to support its urgent timeline. The program received $350,000 from Michigan's recently approved state budget and nearly $900,000 from the Great Lakes Fishery Trust.1 Collection of spawning fish for genetic rescue is set to begin this fall.1 The commercial catch has plummeted from 6.9 million pounds in 2009 to less than 2 million pounds last year, underscoring the severity of the crisis.1 Compounding these challenges, parts of Lake Michigan and Lake Huron have experienced virtually no juvenile whitefish survival to adulthood over the past two decades.1
The scope of the challenge is substantial, as Lake Michigan and Lake Huron together support 18 distinct whitefish populations, with most facing endangerment.1 Doug Craven, natural resources director for the Little Traverse Bay Band of Odawa Indians, emphasized the urgency: "If we don't do this this year, we may not have enough wild fish to rescue down the line."1 Beyond state action, Michigan representatives Debbie Dingell and Tim Walberg have jointly proposed federal legislation to invest $500 million over the next decade in mussel control research.1 Long-term funding remains a critical obstacle to sustaining the rescue effort beyond its initial phase.1
