Problems solved by technology

[0003] However, in the current fish farming process, there is no systematic water quality analysis and control method, most of them only stay at the experience level, a few monitor a few parameters, companies sell a few water adjustment products, when to use, how much to use, and how long the course of treatment is None of them are clear, and a set of effective methods for guiding water transfer has not been formed. It is difficult to use modern instruments to accurately grasp and control the aquaculture water body. Often due to poor control of the aquaculture water body, diseases continue to occur, and serious poisoning, hypoxic death fish
Some even lead to blue-green algae outbreaks, pollute water bodies, and damage the sustainable development of fisheries

Embodiment 1

[0027] The present embodiment is aimed at the diagnosis and regulation of the entire culture cycle of a fish pond that mainly raises grass carp. During detection, choose a representative point in the pond, use a water collector to get 1.0, 1.2 or 1.5 liters of water 20, 25 or 30cm away from the water surface. Analysis and control of water, including algae phase analysis and control, toxic and harmful substance analysis and control, water pH value analysis and control, and dissolved oxygen analysis and control:

[0028] The algae phase analysis takes the content of living chlorophyll a in the water as the main index, and the water body COD Mn Value and alkalinity are secondary indicators: when the content of living chlorophyll a is lower than 90μg / L, continue to analyze the COD of the water body Mn value and alkalinity, when COD Mn When the value is lower than 4mg / L and the alkalinity is lower than 70mg / L, then add algae nutrients to adjust; when the content of living chloroph...

Embodiment 2

[0038] This embodiment is on the basis of embodiment 1, for the water quality diagnosis and regulation of another fish pond where grass carp is mainly raised by another farming household: choose a representative point in the pond, use a 1.0-liter water collector (with a thermometer) at a distance from the water surface Collect 1.0 liter of water from 20-30cm of water. Carry out the following detection and analysis respectively:

[0039] First, the content of living chlorophyll a in the water body is detected to be 60 μg / L, and the corresponding parameter values ​​in Table 1 are lower than the lower limit, indicating that the amount of algae in the water body has not met the design requirements, and the amount of algae needs to be increased; then the ammonia nitrogen is 1.87mg / L L, nitrite nitrogen is 0.61mg / L, and the corresponding parameter value of comparison table 1 shows that these two parameters are in the state of exceeding the standard, and the fish has appeared to floa...

Abstract

The invention discloses a fresh water pond's water quality diagnosing, regulating and controlling method. On the basis of the water analysis, a variety of regulating modes are used for the continued diagnosing, regulating and controlling of the water so as to achieve the purpose for stable water and to create a stable and comfortable environment for the bred objects. With the method, the propagation of pathogenic bacteria in a breeding cycle is inhibited, which reduces the occurrence of diseases, thus reducing the use of drugs and promoting growth. The cultivated algae serve as natural fish baits, which can make up for the shortage of the injected forage and the nutritional imbalance. The experiment using the method finds that under the same breeding condition, the annually injected feeding amount can be reduced by 10%, therefore, reducing the cost while increasing the fish production; in addition, the method also protects the water environment and provides consumers with healthy and safe aquatic products.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a freshwater pond water quality diagnosis and control method. Background technique [0002] In the new situation of vigorously promoting the construction of modern fishery and implementing the concept of healthy farming, how to maintain the green mountains and green waters in the environment and maintain the friendly breeding water body, and at the same time maximize the development and utilization of the breeding water surface to ensure the quality and safety of aquatic products and achieve fishery efficiency. , Fisherman's income increase and the purpose of making fishery sustainable development are an important topic in front of aquatic practitioners. [0003] However, in the current fish farming process, there is no systematic water quality analysis and control method, most of them only stay at the experience level, a few monitor a few parameters, companies se...
