Self-floating feed type culture method for benthic fishes

Abstract

The invention discloses a self-floating feed type culture method for benthic fishes, and belongs to the technical field of aquaculture. The structure of feed is improved, the feed firstly sinks into the water bottom to wait, water flow caused by swimming of fishes is used as a trigger condition when the fishes find food nearby, sensing capsule pieces on the feed induce resonance after sensing water flow changes, vibration is transmitted into disintegration assisting capsule rods in the feed, friction bodies in thermal triggering balls are driven by magnetic force to conduct repeated friction again to generate heat to heat thermal decomposition layers, the thermal decomposition layers are forced to be subjected to decomposition reaction to release gas, the disintegration assisting capsule rods are filled with the gas to continuously expand to finally form broken holes in the surface of the feed, then the spherical feed is inflated to expand to increase the buoyancy of the feed to startfloating, fishes can directly observe the feed, meanwhile, the feed starts to disintegrate to facilitate fish feeding, and the utilization rate of the feed and the feeding rate of the fishes are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a self-floating culture method for benthic fish. Background technique [0002] Aquaculture is the waters that humans use for breeding (including planting). According to the ecological habits of the breeding objects and the requirements for the environmental conditions of the waters, aquaculture technology and facilities are used to engage in aquatic economic animal and plant breeding. one. According to the nature of the waters, it is divided into marine aquaculture and freshwater aquaculture. According to the breeding and planting objects, it is divided into fish, shrimp and crab, shellfish, algae, gorgon, lotus, lotus root, etc. The aquaculture industry in China has a long history, as far back as 1142 BC (the end of the Yin Dynasty and the beginning of the Zhou Dynasty), it was known to dig ponds to raise fish. Fan Li wrote the "Fish Culture Classic" around 460 BC, which i...

Problems solved by technology

[0004] When breeding bottom-dwelling fish, sinking feed is mostly used for feeding, but the environment of the breeding site is generally more complicated, not only there are many original features, but also the excrement of the fish itself will hide part of the feed. It is difficult for fish to find and eat. On the one hand, it will cause some waste of feed and increase the cost of breeding. On the other hand, it may lead to the phenomenon that the fish do not eat enough and affect the growth, thereby reducing the breeding efficiency.
