斯里兰卡Deduru Oya水库中的入侵性蛇头鱼正在损害当地物种和渔民的生计,这促使人们作出新的努力,如角鸟旅游和食品加工,以控制它们的传播。 Invasive snakehead fish in Sri Lanka’s Deduru Oya reservoir are harming native species and fishers’ livelihoods, prompting new efforts like angler tourism and food processing to manage their spread.

在斯里兰卡的Deduru Oya水库中,过去两年入侵性蛇头鱼猛增,威胁到当地物种和传统渔业生计。 In Sri Lanka’s Deduru Oya reservoir, invasive snakehead fish have surged over the past two years, threatening native species and traditional fishing livelihoods. 据信是从装饰型坦克中释放出来的,侵略性的、呼吸空气的鱼类没有天然的掠食动物,现在体重高达7公斤。 Believed to have been released from ornamental tanks, the aggressive, air-breathing fish have no natural predators and now weigh up to 7 kilograms. 据渔民报告,虾和当地渔获量急剧下降,传统渔网没有效力。 Fishers report sharp declines in prawn and native fish catches, with traditional nets ineffective. 虽然先前的捕鱼竞争未能遏制数量,但当地人现在正在推动角鸟旅游,将蛇头加工成盐干美味的咸干熟食,以赢得优势的受欢迎程度,以此作为控制人口和创收的可持续方式。 While a prior fishing competition failed to curb numbers, locals are now promoting angler tourism and processing snakeheads into salted dried delicacies—gaining niche popularity—as sustainable ways to control the population and generate income.
