Fish farms have a big problem: They’ve been making feed out of sardines
and anchovies from the oceans, a source that could be depleted within a

solution: They’ve developed the first completely vegetarian fish feed to
be used commercially in the U.S., with the help of a USDA scientist who
has made fish nutrition his life’s work. (Video by: Alan Jeffries, Amy
