Problems solved by technology

[0002] Bionic bait includes bionic shrimp, bionic small fish, bionic earthworm, etc. The existing bionic bait is mainly processed from transparent silica gel, which has certain elasticity. There are problems or defects, and it emits a faint leather smell. This smell is significantly different from the fishy smell of food. When it is serious, it has the effect of repelling fish. Fish don't like it or even reject it. Entering rivers and ponds will cause pollution to rivers and ponds, especially after being swallowed by fish, it will affect the life safety of fish in the water, so a bionic bait that can automatically degrade in the water is needed to avoid damage to the pond. and river pollution

Abstract

The invention discloses a degradable bionic bait prepared from a polyvinyl alcohol material, which is prepared from the following raw materials in parts by weight: 10 to 15 parts of polyvinyl alcohol 1788, 10 to 15 parts of polyvinyl alcohol 1799, 1 to 3 parts of alkylphenol sulfate salt, 15 to 20 parts of polymerized starch, 0.2 to 0.3 part of a phagostimulant, 2 to 3 parts of filler, 3 to 5 parts of modified chitosan gel and 0.1 to 0.2 part of pigment. The defects in the prior art are overcome, and the degradation performance and the elasticity of the bait are effectively improved.

Description

technical field [0001] The invention relates to the technical field of bionic fishing bait, in particular to a degradable bionic fishing bait prepared from polyvinyl alcohol material. Background technique [0002] Bionic bait includes bionic shrimp, bionic small fish, bionic earthworm, etc. The existing bionic bait is mainly processed from transparent silica gel, which has certain elasticity. There are problems or defects, and it emits a faint leather smell. This smell is significantly different from the fishy smell of food. When it is serious, it has the effect of repelling fish. Fish don't like it or even reject it. Entering rivers and ponds will cause pollution to rivers and ponds, especially after being swallowed by fish, it will affect the life safety of fish in the water, so a bionic bait that can automatically degrade in the water is needed to avoid damage to the pond. and pollution of rivers.
