Fish phagostimulant effect evaluation method and system based on microscopic hyperspectrum

Abstract

The invention relates to the field of spectrum detection technology and aquatic feed, and discloses a method and a system for evaluating the effect of a fish phagostimulant based on microscopic hyperspectrum. The method comprises the following steps: performing spectral difference analysis on local space and spectral information of intestinal tissues of test fish through a hyperspectral image, accurately identifying and detecting an enrichment area of digestive metabolites, and quantitatively calculating a food calling digestion coefficient; the effect of the phagostimulant is further analyzed and evaluated according to the phagostimulant growth index of the tested fish; the effect of the composite phagostimulant can be rapidly and accurately evaluated under the condition that the phagostimulant mechanism is not clear yet, so that the purpose of detecting whether the effect of the fish phagostimulant reaches the standard or not is achieved.

Description

technical field [0001] The invention relates to the field of spectral detection technology and aquatic feed, in particular to a method and system for evaluating the effect of a fish attractant based on microscopic hyperspectral. Background technique [0002] Food attractants, also known as attractants and appetite enhancers, are often used in aquatic feeds to improve the palatability of feeds, and can effectively increase the appetite of aquatic animals and promote the growth of aquatic animals. Among them, the attractant includes bait attracting substances and bait stimulating substances. Fish and shrimp mainly sense the attracting effect through smell and taste. Adding fish attractant to aquatic feed can stimulate the tendency behavior of fish in terms of color, odor or taste, and attract fish to the vicinity of the feed to speed up the process. The feeding speed of fish reduces water pollution and increases appetite to promote digestion and absorption of fish. [0003] ...

Problems solved by technology

However, due to the complexity of its compound components and the unclear mechanism of food attractants, there is still a lack of a scientific, accurate and efficient evaluation method for the effect of fish food attractants on compound food attractants. It is difficult to ensure the quality of aquatic products and improve the efficiency of breeding by realizing the rapid and accurate evaluation of the effect of compound food attractants
