When the feeds are fed to an aquarium or a pond, (1) flaky flakes are fluttering. Slowly settles and sinks to the bottom, (2) Sinks and sinks to the bottom while collapsing over time while floating on the water surface, (3)
There are various types such as when they are thrown in, they settle down quickly and sink to the bottom. As feeds for cultured fish, natural feeds (small crustaceans such as rotifer and artemia, seafood, minced meat) and mixed feeds (moist pellets, pellets, granules,
Some are made from fish meal such as fine particles), but when fed to aquaculture ponds or farms, they quickly settle and sink to the bottom.

ある。Recently, among ornamental fish (tropical fish, goldfish, carp, etc.), tropical fish are becoming more popular. This is because (1) there are few restrictions on raising tropical fish as pets, it can be raised even in an apartment, etc., it is okay without feeding for several days, (2) an aquarium is placed in the room and enjoyed as an interior The reason is that the number of people has increased. In the market, there are an increasing number of people, including those who are enthusiastically bred to amateurs who are bred easily, and there is a demand for the development of feed that is easy to handle even for amateurs. That is, what is required of the feed is (1) not polluting the water, (2) feeding the fish with different growth depths together in the aquarium in order to keep them together. The cause of water contamination is often caused not only by the excrement of fish, but also by the food left behind and the food sinking to the bottom and decaying. Therefore, there is a demand for foods that are of interest to fish and that are easy to eat, foods that do not remain submerged in the bottom of an aquarium, and foods that are left over from food that can be removed by scooping with a net or overflowing water if necessary. On the other hand, looking at the feed for cultured fish, especially among the cultured fish, the juvenile to intermediate-cultured fish have not yet sufficiently developed the ability to move around in pursuit of the feed, and therefore, the feed having high floatability and the sedimentation speed The fast feed often flows out of the area or settles to the bottom and becomes sludge without being eaten by farmed fish. This causes more water pollution than excrement of farmed fish. In this way, the conventional feed has the unidirectional behavioral property that (1) floats while (2) sinks.
For fish who are interested in moving things as food,
The feed is not very interesting, and the feeding efficiency of fish is not very good. As a result, the fish do not eat the sedimented leftover food, but it rots and becomes a source of water pollution. Regarding the drug for fish, when treating diseased fish with the drug, the drug is dissolved in breeding water and immersed therein. There is a "medicine bath" and an "oral administration" in which a drug is added to feed and it is given to diseased fish. However, the reality is overwhelmingly a medicated bath. Since the method of the medicated bath requires the use of a large amount of medicine,
Not only the cost but also the pollution problem caused by its use must be considered. Therefore, an oral administration method is conceivable, but it is troublesome, time-consuming, and difficult for the breeder to mix the medicine with the feed and give it. Therefore, it is preferable that the medicine can be separately orally administered separately. Therefore,
It is an object of the present invention to provide a feed or a drug having a property of slowly settling once when a feed is fed or when a drug is administered and slowly rising again after a few minutes.

ぐことができる。[Effect] The following effects are produced by using the feed having the sedimentation and re-floatability. (1) It is possible to feed fresh fish, whether it is bottom fish, fish near the surface of water, or fish at any depth. (2) The fish are interested because the food is always moving,
Eat well (3) Since the feed passes in front of the fish twice when it sinks and when it floats, the chances of feeding it increase even for fry who have a weak ability to pursue food. (4) The leftover food does not accumulate on the bottom, which does not cause water pollution. (5) The uneaten food comes to the surface of the water, so it is easy to collect it if necessary. (6) Since the bait moves slowly at all water depths, fish living at any water depth can eat the bait in front of them. (7) Since the chemicals for fish settle and float, the fish are easy to eat and the drug is unlikely to remain in the aquarium. (8) The chemicals for fish left over from the surface can be recovered if necessary, and problems due to residual drug damage can be prevented.
