“Juicing” Alfalfa for a Sustainable Aquaculture

Cows and horses aren't the only fans of alfalfa. Yellow perch like it, too. ARS scientists in Madison, WI, are experimenting with alfalfa as a promising alternative to using fishmeal, a protein-rich ingredient in aquaculture feeds given to "farm-raised" finfish and shellfish.

There’s concern that increasing consumer demand for aquaculture products like these will outpace what the ocean's wild-caught stock of sardine, anchovy, menhaden and other small forage fish can supply as a fishmeal resource for aquafeeds. Nutritious, affordable, plant-based alternatives could help ease the burden on these forage fish populations, which are important members of the marine ecosystem and its inhabitants, particularly larger predatory species.
