目前,美国人越来越爱吃日本寿司,而以海藻为食的海胆是日本寿司的主要原料之一,因此,人们发现多吃寿司非常有助于保护该国加利福尼亚州沿海地带正在日渐消失的海藻资源,海藻资源正是加利福尼亚地区生态系统的一个重要组成部分。
据路透社10月30日报道,加利福尼亚州海胆协会表示,那些频繁光顾寿司店的食客们目前正在吃掉越来越多的海胆,而捕捞这种海洋生物已在该州成为了一项年产值达2300万美元的新兴产业。
做为一种多刺的棘皮类动物,海胆对于那些把脚放在暗礁上的海滨游泳者构成了潜在的威胁,这种动物通常以大型海藻为食物,因此海藻在加州沿海地区正呈出日渐减少的趋势。
按照该海胆协会的说法,加州潜水员们现在每年下海捕捞的海胆数量已经达到80万磅,而且他们预计全美国对于海胆的需求量仍会继续增涨。随着海胆数量被大量消耗,海藻资源将会得到一定程度的保护。
America's growing appetite for exotic sushi may help preserve vanishing beds of seaweed seen as an important part of the ecosystem along the California coastline.
Diners in sushi restaurants are eating ever greater amounts of sea urchin roe, known as Uni, creating a $23 million (13 million pounds) industry in California for harvesting the creatures, the California Sea Urchin Commission said this week.
The spiny echinoderms, a potential peril to swimmers stepping on rocks, feast on kelp, which is dwindling along California's coastline.
Divers in the state now harvest 800,000 pounds of Uni annually, the Sea Urchin Commission said, adding that it expects growing consumer demand for Uni in the United States.
