Problems solved by technology

[0010] The present invention aims to solve the problem in the prior art that it is necessary to establish a huge amount of basic data and perform evaluation and early warning based on the original data, so that the analysis of the data has a certain lag and is not timely enough
The present invention provides a method for evaluating the water quality of Litopenaeus vannamei culture ponds. Through the method, it can not only solve the problem of determining and grading the water quality standards of Litopenaeus vannamei ponds in actual production due to the need to establish a huge database and the complexity of evaluation and early warning methods It is difficult to classify problems, and it can realize instantaneous data monitoring of pond water quality, timely evaluation and early warning, and provide decision-making for different levels of alarm situations

Embodiment 1

[0056] A method for evaluating the water quality of a Litopenaeus vannamei culture pond, comprising the following method steps:

[0057] A. Put the water quality online detection instrument in the breeding pond to obtain the values ​​of multiple water quality factors;

[0058] B. The data obtained in step A is transmitted to a computer database through wired or wireless transmission;

[0059] C. Carry out single-factor water quality evaluation through the single-factor water quality index evaluation method, and conduct comprehensive pollution index evaluation through the comprehensive pollution index evaluation method; use the above two methods to perform real-time calculation and evaluation of the data in the database;

[0060] D. The obtained evaluation results are sent and displayed on the mobile terminal through wireless transmission for decision-making and countermeasures.

Embodiment 2

[0062] The monitoring probe detected the water quality data of the Litopenaeus vannamei culture pond and sent the data to the database: at 08:30 on October 22, 2015, the water quality status: dissolved oxygen DO=8.87mg / L, ammonia nitrogen content=0.47mg / L, nitrous acid Salt nitrogen content = 0.153 mg / L, pH = 8.41.

[0063] 1. Single factor water quality evaluation method

[0064] 1) Establish single-factor water quality classification, each water quality factor is divided into 5 grades:

[0065] Table 1: Single-factor water quality classification

[0066]

[0067] Among them, the pH monitoring standard is based on two time periods: morning (07:00-12:00) and afternoon (12:00-18:00).

[0068] I DO =C DO / C DO-Ⅰ =8.87 / 8=1.1>1, the dissolved oxygen evaluation result is Class I water quality;

[0069] I NH3-N =C NH3-N / C NH3-N-Ⅲ =0.47 / 0.50=0.94<1, the ammonia nitrogen evaluation result is Class II;

[0070] I pH =C pH / C pH-Ⅰ =8.41 / 7.7=1.09>1, that is, the pH evalu...

Embodiment 3

[0102] The monitoring probe detected the water quality data of the Litopenaeus vannamei culture pond and sent the data to the database: at 08:30 on August 19, 2015, the water quality status: dissolved oxygen DO=8.63mg / L, ammonia nitrogen content=1.78mg / L, nitrous acid Salt nitrogen content = 1.972mg / L, pH = 8.76.

[0103] 1. Single factor water quality evaluation method

[0104] 1) Establish single-factor water quality classification, each water quality factor is divided into 5 grades:

[0105] Table 1: Single-factor water quality classification

[0106]

[0107] Among them, the pH monitoring standard is based on two time periods: morning (07:00-12:00) and afternoon (12:00-18:00).

[0108] I DO =C DO / CDO-Ⅰ =8.63 / 8=1.08>1, the dissolved oxygen evaluation result is Class I water quality;

[0109] I NH3-N =C NH3-N / C NH3-N-Ⅴ =1.78 / 1.0=1.78>1, the evaluation result of ammonia nitrogen is Class V;

[0110] I pH =C pH / C pH-Ⅰ =8.76 / 7.70=1.13>1, that is, the pH evaluat...

Abstract

The invention relates to a method for evaluating water quality of a Litopenaeus vannamei culture pond and belongs to the technical field of aquaculture. The method comprises the steps of transmitting data acquired by an online water quality detecting instrument to a computer database, carrying out single-factor water quality evaluation by adopting a single-factor water quality index evaluation method, then, carrying out comprehensive pollution index evaluation by a comprehensive pollution index evaluation method, sending an obtained evaluation result to a mobile terminal through wireless transmission, and displaying the evaluation result on the mobile terminal so as to make a decision and then make counter measures. According to the method, not only can the problem that standard determination and grade classification for the water quality of the Litopenaeus vannamei pond are difficult in actual production due to the fact that a huge database is required to be established and evaluating and warning methods are complicated be solved, but also instant-data monitoring for the water quality of the pond, timely evaluating and warning and decision providing for warning instances of different grades can be achieved.

Description

technical field [0001] The invention relates to a method for evaluating water quality, more specifically, the invention relates to a method for evaluating water quality in a culture pond of Litopenaeus vannamei, belonging to the technical field of aquaculture. Background technique [0002] my country is a big country in prawn farming. The output and scale of prawn aquaculture ranks first in the world in recent years. Among them, Litopenaeus vannamei is the main species of prawn farming. Shrimp farming is difficult, and the output continues to decrease. Shrimp farming is facing great challenges. "Farming shrimp is raising water". The quality of water is the key to the success of Litopenaeus vannamei farming. The impact of water quality on the growth, feeding and immunity of prawns cannot be ignored. Good water quality conditions are conducive to the stability of the micro-ecological environment of the breeding system and reduce the occurrence of diseases. Therefore, the fin...
