Seamounts are one of the most common oceanic ecosystems in the world. Interactions between seamounts and underwater currents attract plankton, corals, fish, and cetacea alike. Their effect has been noted by the commercial fishing industry, and many seamounts support extensive fisheries. There are concerns about the effect of fishing on seamount ecosystems. There are well-documented cases of stock decline. 95% of ecological damage is done by bottom trawling, which literally scrapes whole ecosystems off seamounts.
