Abstract
The invention relates to ecological artificial bait for tuna longline and a preparation method therefor. The bait contains the following main constituent materials: a bait skeleton and bait film coating (outer coating) materials, wherein the bait skeleton is prepared from artificial or natural, degradable and harmless materials, and the density of the materials is higher than that of sea water, and the bait film coating (outer coating) materials contain adjuvants such as polyvinyl alcohol (PVA), polycaprolactone (PCL), poly(butylene succinate) (PBS), aliphatic polycarbonate (APC), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), styrene-ethylene / butadiene-styrene copolymer (SEBS), sodium alginate (SA), hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), protein, amino acid, starch, glycerine and cane sugar, as well as a fish luring agent, a coloring agent, an illuminating agent and the like. A film coating, which is proper in material density and has good dispersing and fish luring agent slow-releasing capacity, can be prepared through mixing the film coating materials at a proper ratio; and the ecological artificial bait is ideal in rigidity, toughness and weather resistance, excellent in mechanical properties, breakage resistance and tear resistance and easy to operate, transport and store. The novel ecological artificial bait can be prepared by a simple process and has a very good simulated effect, thereby being capable of replacing the traditional fresh bait.
Description
technical field [0001] The invention relates to the technical field of an ecological artificial bait for tuna longline fishing, in particular to the use of degradable materials as the main material of the artificial bait. This artificial bait can be naturally degraded in the marine environment without causing harm to the environment. The invention also relates to methods of using these materials to make lures. Background technique [0002] In recent years, due to the decline of offshore fishery resources and the successive entry into force of China-Japan, China-Korea, and China-Vietnam fishery agreements, my country's marine fishing industry is facing an unprecedented severe situation. For this reason, the national marine fishery policy actively encourages the development of pelagic fishery. Among them, tuna fishery Because of its considerable economic benefits and rich fishery resources, it has become the most important part of the development of my country's pelagic fishery...
