A feed distributor used in fish ponds with feed supplied from below and thrown circumferentially comprises a feed-supplying mechanism, a feed-throwing mechanism and a feed-conveying mechanism by which feed supplied from said feed-supplying mechanism is delivered to said feed-throwing mechanism; the feed-supplying mechanism has a hopper which connects with a feed container above and a feed conveyor below. The feed-throwing mechanism has a launching disc with a sealed top, feed outlets in its circumference and a feed inlet below. The launching disc is disposed on a hollow shaft with an inner hole opposed to said feed inlet. The feed-throwing mechanism is disposed in pond and the feed supplying mechanism settles on a bank, feed is sucked into the feed-throwing disc and thrown circumferentially under negative pressure caused by rotation of the launching disc, and has a low crushing rate.
