Description of Method - Triploid Grass Carp. The grass carp, also known as the white amur, is a vegetarian fish native to the Amur River in Asia.

In some situations, sterile grass carp may be permitted for introduction into Washington waters.
Scallops filter plankton from the water internally. Squid eat small fish which eat plankton, and even the mighty humpback whale dines on small fish which eat plankton.

So, nearly everything in the ocean somehow depends on the zooplankton.
