"HONOLULU - Biologists fighting invasive seaweeds taking over Hawaiian reefs are using native sea urchins and fish to help control the aggressive plants. "If people can raise herbivore (plant-eating) stocks quite substantially, I believe it will have a big impact," said coral reef ecologist Ivor Williams of the Hawaii Coral Reef Initiative and the state Division of Aquatic Resources.

In tests of weed-infested reefs in Kaneohe Bay, the tactic has been successful and gives hope that the state's coral reefs might be able to battle the plants."

Go, go, sea urchins!

Cheers Amaranth,

There's a lot of doom and gloom about the environment. It is nice to get some positive news.
