通常情况下,软骨藻酸是太平洋沿海的硅藻繁殖时产生的。此类繁殖并不总是危险的。需要营养素、光照,更为重要的是,温水组合在一起才能产生毒素。该毒素会沿着食物链从滤食性贝类传播到螃蟹、海洋哺乳动物,极少情况下,会传播给人类。为保证食品供应安全,当毒素水平过高时,加州官员会关闭渔业。
These closures have been devastating to the Dungeness crab industry, as many publications, including San Francisco Magazine and National Geographic, have reported. The worst closure started in 2017 and lasted for months, costing the industry more than $48.3 million by one estimate and upwards of $117 million by another. The 2016 and 2018 seasons also saw domoic acid delays.
渔业关停对珍宝蟹行业的打击是毁灭性的,正如《旧金山杂志》《国家地理》等刊物所报道的那样。最糟糕的一次关停发生在2017年,关停持续了4个月,使该行业损失超过4830万美元,还有人估计称,此次损失超过1.17亿美元。2016年和2018年也见证了软骨藻酸引起的渔业推迟开业的现象。
An organization called the Pacific Coast Federation of Fishermen's Associations is bracing for a future where climate change ensures that there's plenty of that key ingredient for toxic blooms: warm water. These fishers have connected some worrying dots, from the toxic blooms and warming oceans to climate change and fossil fuels. So the group has taken the extraordinary step of suing 30 major fossil fuel companies: it wants Big Oil to pay for the harm to members' livelihoods, and they want their industry to survive even in a changing climate.
