Problems solved by technology

However, the research on early warning and forecasting technology for aquaculture diseases started relatively late, and it is rarely used in the mariculture industry. At present, there is no early warning method for sea cucumber breeding diseases

Embodiment

[0050] The monitoring data of japonicus breeding ponds are shown in Table 1, stored in the form of Ecxel table, imported into the early warning model of japonicus japonicus disease, and selected the prediction method based on regression analysis for early warning analysis, the prediction result output by the system is 37.15%, and the probability of disease occurrence is relatively low. Small; in the same period, the offshore monitoring data was predicted to be 47.96% by the same method. At this time, it is not suitable for water exchange with the open sea. Some higher indicators such as pH and chemical oxygen consumption can be adjusted by adding probiotics.

Abstract

The invention discloses a disease pre-warning system for a stichopus japonicus. The disease pre-warning system is used for monitoring main factors (such as temperature, salinity, pH, dissolved oxygen, chemical oxygen consumption, pathogen number change) in a stichopus japonicus cultivation environment; applying a disease pre-warning model to analyze monitoring data; pre-warming a disease generation probability of the stichopus japonicus and putting forward prevention and control measures; and releasing pre-warming information through mobile phone messages or a network platform, wherein a disease pre-warming model screens out main environmental factors which remarkably affect growth and healthy cultivation of the stichopus japonicus after analyzing and researching long-term monitoring data of the stichopus japonicus cultivation environment; through an orthogonality simulation experiment, influence of each main factor to a death rate is analyzed in a mode that a telophase death rate of the stichopus japonicus is used as indexes while an experiment is ended; and based on a great number of data obtained from the experiment, an established pre-warming model based on a SQL Server (Structured Query Language Server) relationship databank engine comprises prediction methods, such as a regression analysis, a relevance regulation analysis, an expertise analysis, a rational analysis on storage, a neural network analysis.

Description

technical field [0001] The invention relates to the field of sea cucumber cultivation, in particular to a sea cucumber disease early warning system. Background technique [0002] Sea cucumber (Apostichopus japonicus) is mainly distributed in the Yellow and Bohai Sea regions of China. Because of its good quality, high economic value, and increasing market demand, it has become an important breeding species in Shandong, Liaoning and other regions. It is one of the pillar industries of the marine aquaculture industry in the region. In recent years, with the expansion of offshore aquaculture scale and the increase of aquaculture density, the water environment has gradually deteriorated, and the harm of pathogenic microorganisms has become increasingly serious. The disease problem has become one of the bottleneck factors restricting the sustainable development of japonicus aquaculture. At present, in the process of sea cucumber cultivation, a large number of antibiotics and chem...
