Abstract
A feeder for larval and juvenile fishes is capable of delivering a small (ca. 15 mg) precise dose of microparticulate (ca. 100 μm diameter) feed to selected locations, via pneumatic conveyance and control. A source of low-pressure dry gas is used to blow microparticulate feed through a manifold and into a selected one of a number of tubes. A terminal valve at the end of the tube is selectively activated to send the feed to a selected tank or pond. When not in use, the feeder is sealed, and the feed protected from moisture and ambient oxygen.
