Abstract

The invention relates to evaluation of a fish growth speed by a fuzzy matter-element model method according to computer programming and aims to overcome the defects of inconsistent standard, poor quantitative feature, low efficiency and the like of the conventional fish growth speed evaluation method. Technology and device for automatic storage and processing of classification data are provided. The technology has the characteristics of quantitative evaluation, uniform standard and wide application range and plays an important practical role in fishing management on lakes and rivers.

Description

technical field [0001] The invention belongs to a fish growth suitability evaluation based on a fuzzy matter-element model, and relates to a technology and a device for realizing multi-objective fuzzy matter-element evaluation by computer programming, and automatically storing and processing identification data. Background technique [0002] Many experiences at home and abroad have shown that the evaluation of fish growth suitability in rivers and lakes is a key link in the estimation of minimum ecological flow and ecological comprehensive evaluation of the watershed, and the evaluation of fish growth suitability in rivers is also closely related to fish migration. There is no unified standard method for the evaluation of fish growth suitability in rivers and lakes. In the past, the evaluation of fish growth suitability mostly used qualitative methods, which could not quantitatively analyze the growth rate of fish. The method adopts a fuzzy matter-element model and realizes ...
