<br />Research, manufacturing know-how and extensive field testing in all types
<br />of feeding situations is what keeps the Sweeney Aqua-Feeders head and
<br />shoulders above the rest.
<br />For hatchery, tank, raceway and pond Sweeney has a feeder to fit the situation. Choose from
<br />various sizes and types of vibratory feeders, drop feeders or scatter type feeders.
<br />Whether the feed is the difficult-to-dispense larval feed, finely ground starter, crumbles or cat-
<br />fish pellets there is a Sweeney feeder to automatically dispense the exact amount on
<br />a preset schedule.
<br />To go with the feeders there are Sweeney Timers and Controllers that can be
<br />programmed to turn your feeder on and off at any frequency you may desire. You
<br />may feed as frequently as every one second or as infrequently as once every 24
<br />hours; and, the duration of the feed run can be set from .1 second to 99.9 seconds.
