Abstract

The application relates to the technical field of marine organism phagostimulant, and particularly discloses an artificial phagostimulant and application thereof in conch fishing. The artificial phagostimulant comprises one or more of glutamic acid, taurine, inositol and lactic acid. According to the application, four key active ingredients of the mollusk phagostimulant are systematically identified from the shark meat, and one or more of the four key active ingredients of glutamic acid, taurine, inositol and lactic acid are used as artificial phagostimulants, so that a good phagostimulant effect can be achieved on the mollusk, and when the four active ingredients are used together, the phagostimulant effect can be equivalent to that of the traditional shark meat, so that dependence on the scarce shark meat resources is effectively reduced, the problem of unstable effect of the traditional phagostimulant material is solved, and important scientific basis and technical support are provided for the research of the mollusk chemical ecology and the development of other marine mollusk phagostimulants.

Description

Artificial phagostimulant and application thereof in conch fishing Technical Field The application relates to the technical field of marine organism phagostimulant, in particular to an artificial phagostimulant and application thereof in conch fishing. Background The conch is an important economic shellfish in the northern sea area, and has higher edible value and economic value. Along with the continuous increase of market demands, the fish-catching device becomes an important catching object in northern sea areas in China, the annual output reaches tens of thousands of tons, and the output value reaches billions yuan. In the fishing process of the conch, the phagostimulant technology is the most main fishing method, and conventionally, animal baits such as shark meat, fish viscera and the like are mostly adopted as phagostimulant, and the conch is attracted to gather and enter a trap device by releasing chemical signals. The shark meat is widely applied to the conch fishing operation due to the strong feeding effect, and becomes a high-efficiency feeding material accepted in the industry. Although the traditional phagostimulation method can utilize the sharp chemical sensitivity of the conch to form a chemical gradient field in the sea water so as to guide the conch to actively swim to a fishing area, a plurality of problems still exist. Traditional food-attracting material resources such as shark meat are increasingly scarce, the price is continuously rising, and the food-attracting material is limited by environmental protection policies, so that the obtaining channel is strictly controlled. Moreover, these natural materials are prone to deterioration, are difficult to preserve, require low temperature Leng Lian for transportation, and severely increase the use cost. In addition, the natural phagostimulant is unstable in component composition, and the phagostimulant effect is different from batch to batch, so that the stability and predictability of the fishing operation are difficult to ensure. For this reason, researchers have attempted to isolate and identify key phagostimulant active ingredients from natural high-efficiency materials, and to identify specific active molecules through systematic ingredient screening and biological activity verification, thereby developing artificial phagostimulants. However, people still lack the accurate identification capability of active ingredients, so that the fact that which chemical substances in natural high-efficiency materials such as shark meat are true phagostimulant active ingredients cannot be completely determined, and therefore, the conventional artificial phagostimulant cannot achieve the standard of the natural high-efficiency materials, cannot realize standardized production and cost control, and still depends on the integral use of the natural materials in industry. Disclosure of Invention In order to solve the technical problems, the application provides an artificial phagostimulant and application thereof in conch fishing. In a first aspect, the application provides an artificial phagostimulant, which adopts the following technical scheme: An artificial phagostimulant comprises one or more of glutamic acid, taurine, inositol and lactic acid. Preferably, the artificial feeding agents include taurine, glutamic acid, creatine and lactic acid. By adopting the technical scheme, the application determines that four key active components which play a role in phagostimulation of the conch in the shark meat are glutamic acid, taurine, inositol and lactic acid based on the metabonomics analysis result of the shark meat, and then respectively verifies the phagostimulation effects of the four active components when the four active components are singly used and are compounded in different combination modes for use. According to the analysis of the comparison experiment result, glutamic acid, taurine, inositol and lactic acid can have a phagostimulant effect on the conch when being singly used, and the phagostimulant effect of the four active components shows the strong and weak sequence of taurine, glutamic acid, inositol and lactic acid. Meanwhile, experimental data show that in a plurality of different combination modes, when the four active ingredients of glutamic acid, taurine, inositol and lactic acid are used together, the food calling effect is obviously better than that of a single active ingredient, and can be equivalent to that of the traditional shark meat. The four active ingredients can fully exert the synergistic interaction when being used together, effectively improve the foraging reaction intensity and the liveness of the conch, and show excellent food calling performance. In the application, when the metabonomics of the shark meat is researched and analyzed, the traditional method for determining the key substances only by the content of the substances is not adopted, the substances in the metabonomics are firstly subjected to contribution
