We’ll be sending submersibles into the Zemchug and Pribilof canyons to document the effects of bottom trawling. Then we’ll go to small fishing communities along the coast to share what we find.

我们将往珍楚溪谷（Zhemchug）和普里比洛夫（Pribilof）溪谷送潜水器以证明海底拖网捕捞的影响，然后我们沿着海岸向小型渔民社区展示我们的发现成果。

Campaigners, with the support of marine scientists, have repeatedly tried to persuade countries to agree to an international ban, arguing that the indiscriminate nature of bottom-trawling is causing irreversible damage to coral reefs and slow-growing fish species, which can take decades to reach maturity and are therefore slow to replenish their numbers.
