Ocean warming has led to more whales being entangled in fishing gear off the California coast, according to research published yesterday in Nature Communications.
根據昨天發表在“自然通訊”雜誌上的一項研究，海洋變暖已經導致更多的鯨魚被困在加州海岸的漁具中。
The study found connections among changes in forage species from heat waves, a recovery of whale populations and an increased number of whales being entangled in fishing nets.
研究發現，熱浪導致的飼料物種變化，鯨魚種群的恢復，以及被漁網纏住的鯨魚數量增加之間存在聯繫。
And the paper proposes an index for assessing the risks to marine life and fisheries' economic stability.
並提出了評估海洋生物和漁業經濟穩定性風險的指標。
"Warming of the ocean is impacting the ecosystem shift, and so we've had to come up with a new index to better monitor it," said Jarrod Santora, the study's lead author, an ecosystem oceanographer with NOAA Fisheries and an associate researcher at the University of California, Santa Cruz.
“海洋變暖正在影響生態系統的轉變，所以我們必須想出一個新的指標來更好地監測它，”該研究的主要作者、NOAA漁業的生態系統海洋學家、加州大學聖克魯茲分校(University of California，Santa Cruz)的副研究員賈羅德·桑托拉(Jarrod Santora)說。
Major marine heat waves from 2014 to 2016 reduced offshore krill populations, which left migrating humpback whales hungry and searching for anchovies along the coast near active fisheries.
2014至2016年間的主要海洋熱浪減少了近海磷蝦種群，導致遷徙的座頭鯨飢餓，並在活躍漁業附近沿海岸搜索鳳尾魚。
Additionally, the massive 2019 heat wave, also known as "the blob," delayed the crab season, which exacerbated the issue of whale entanglements.
此外，2019年的大規模熱浪，也被稱為“斑點”，推遲了螃蟹季節，這加劇了鯨魚糾纏的問題。
"That switch from feeding in the oceanic environment in the outer shelf break to the near-shore environment coincided with this amplified co-occurrence between whales and fishing gear," Santora said.
桑托拉說：“從在外大陸架斷裂的海洋環境中覓食到近岸環境的轉變，與鯨魚和漁具之間的這種放大的共生現象相吻合。”
