Fish feed is one of the necessary conditions for fish farming, and among the types of fish feed, sinking feed and floating feed are indispensable. The difference between the two feeds is not only reflected in their form, but also in their application scenarios and applicable objects. This article will give a detailed introduction to the difference between sinking and floating feed in fish feed, to help farmers better choose the fish feed that suits them.

Definition of sinking fish feed

Sinking fish feed refers to materials made of higher density, and its density is generally between 1 and 4, which has the ability to sink to the bottom. Sinking feed can also be made by adding a mixture of water and feed to a certain degree of specific gravity to meet the dietary needs of fish. The shape of sinking fish feed is mostly granular, of different sizes, and can vary according to the type of fish.

Definition of floating fish feed

Floating fish feed is made of foaming agent and other materials, with a low density, generally between 0.2 and 0, and has the ability to float on the water. The floating material itself does not contain water, but needs to be mixed with water and feed during production. The shape of floating material is mostly spherical or flake, and the size is smaller than sinking material.

Differences between the two types of feed

Different applicable objects

Sinking fish feed is suitable for fish with larger bodies and larger mouths, such as koi, carp, black carp, and grass carp. This is mainly because the oral structure and feeding method of these fish are most compatible with sinking feed, and they can get food by diving, so using sinking feed can ensure that the feed is fully digested and absorbed. Floating fish feed is suitable for small fish with smaller mouths, such as goldfish, clownfish, and jellyfish. This is mainly because these fish like to forage on the water surface, so using floating feed can make it easy for them to get enough nutrition.

Different sinking and floating properties

Since a higher density material is added when making fish feed sinking, it has a higher density and sinks to the bottom. Floating fish feed has the ability to float on the water surface, mainly because foaming agents and other lightweight materials are used during production. The different sinking and floating properties of the two feeds make them different in feeding methods.

Different nutritional components

The nutritional components of sinking fish feed and floating fish feed are also different. Sinking feed is mainly composed of some sediments and proteins, which is very beneficial for large fish that need to consume energy and protein for a long time, and can provide them with sufficient nutrition. Floating feed is mainly composed of protein, which can meet the protein needs of small fish.

Different influences of water environment

Since the characteristic of sinking feed is to sink to the bottom, it is less affected by the water environment. Floating feed is directly exposed to the water surface. In addition to the influence of water quality, it is also affected by natural factors such as sun and rain. When choosing fish feed, in addition to considering the type and size of fish, it should also be considered comprehensively in combination with the breeding environment and climate factors.

Conclusion:

As an indispensable part of the breeding industry, the difference between sinking and floating feed in fish feed lies in the applicable objects, sinking and floating properties, nutritional components and the influence of water environment. Choosing a feed that suits you can help fish farmers achieve better results in breeding and improve the survival rate and growth rate of fish.
