在俄勒冈州的威拉梅特河中发现了一只被禁的中国手套螃蟹,引起人们对生态系统破坏和蔓延的担忧。 A banned Chinese mitten crab was found alive in Oregon’s Willamette River, raising concerns about ecosystem damage and spread.

在Sellwood大桥附近的Willamette河中发现了一只中国小螃蟹,这是俄勒冈州禁止的入侵物种,它是活生生的,是今年经证实的第二次目击事件。 A Chinese mitten crab, an invasive species banned in Oregon, was found alive in the Willamette River near the Sellwood Bridge, marking the second confirmed sighting this year. 国家生物学家正在利用陷阱、水采样和调查来调查潜在的扩散,因为螃蟹可以破坏基础设施、破坏生态系统和威胁本地物种。 State biologists are investigating potential spread using traps, water sampling, and surveys, as the crabs can damage infrastructure, disrupt ecosystems, and threaten native species. 与原生螃蟹不同,它们生活在淡水中,并迁移到咸水中繁殖。 Unlike native crabs, they live in freshwater and migrate to brackish water to breed. 官员警告螃蟹可能通过食品贸易非法进入, 并敦促公众通过俄勒冈入侵物种热线报告目击或销售情况。 Officials warn the crabs may enter illegally through the food trade and urge the public to report sightings or sales via the Oregon Invasive Species hotline.
