Decline of Alaskan Snow crab 松葉蟹消失

Using a combination of survey data and laboratory studies, NOAA Fisheries scientists identified starvation as the most likely cause of mass mortality event during the eastern Bering Sea marine heatwave.

松葉蟹與帝王蟹，是台灣老饕的兩大心頭好，但未來想吃可能也不容易，因為數量驟減，阿拉斯加去年（2022年）關閉了漁場，衝擊當地漁民生計，日本松葉蟹產量同樣大跌，導致去年就創下一隻蟹69萬台幣的競標天價。

“This was kind of an unexpected, punctuated change in their populations,” Szulwalski said. “But I think long term, the expectation is that the snow crab population will move north as the ice recedes and in the eastern Bering Sea, we probably won’t see as much of them anymore.”
