Method for using fish breeding raft structure for raising, observing and collecting

Abstract

The invention discloses a method for using a fish breeding raft structure for raising, observing and collecting. The raft structure comprises a raft body and a throwing device; the raft body comprisesa bottom surface and four side walls; the raft structure also comprise first floaters, second floaters and an air compressor; the first floaters are arranged on the side walls of the raft body and are used for ensuring the floating of the raft structure after water enters the raft body; the second floaters are arranged on the bottom surface of the raft body, can be inflated and deflated, and areused for controlling the floating and sinking of the raft structure; and the air compressor is connected with the second floaters through inflating pipes and is used for inflating. The principle of the method is to realize the feeding of fish through controlling the floating and sinking of the raft structure. The body characteristics of the fish can be observed at a short distance while the fish is fed, and excrement or fish scales of the fish can be collected after the feeding is finished, so that the growth condition of the fish is known, and the problem can be found at the early stages of fish diseases. In addition, the excrement of the fish can be collected for testing, the destruction to the water quality by feed residues is reduced, and the survival rate of fish stocks and fry is improved, so that the method is suitable for promotion.

Description

technical field [0001] The invention belongs to the field of breeding, and relates to a method for using a fish breeding raft structure integrating feeding, observation and collection. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish...

Problems solved by technology

[0004] Common causes of disease include: water pollution and virus infection, resulting in a high incidence of fish disease and low survival rate; the quality of the input bait is poor, and the excess bait cannot
