PROBLEM TO BE SOLVED: To solve such problems that, in feeding aquatic organisms such as fishes under farming, it is difficult to feed an appropriate amount of baits; if an excessive amount of such baits is fed, residues remain, resulting in water pollution, if the amount is too small, the growth of the aquatic organisms is delayed; in particular, since fishes such as flatfish do not eat baits sunk at the bottom but eat only baits in water, residues tend to inevitably accumulate at the bottom; besides, much labor is required because of periodically conducting feeding operations and exchanging water. SOLUTION: A bait 16 for aquatic organisms in the form of a pill made by rounding a semi-kneaded bait or in the form of a pellet is attached to the tip 18 of a thread 15, and then suspended into a predetermined depth under the surface of water to make a feeding, thus facilitating eating the bait for an aquatic organism.
