What is the impact of PH on aquaculture?

In the process of fish farming, there are many factors that affect the health of fish, among which the PH value of the aquaculture water is a very important factor, so specifically what are the main aspects of its impact on fish? The so-called PH value refers to the concentration index of hydroxide ions in the water body. In the process of fish farming, the main factors that affect the PH value in the water are weather, water source, light, medication, algae and organic matter in the water, etc.


1. When the PH value is lower than 6.5, the culture water body is acidic. Acidic water will cause the fish's blood PH value to drop and the concentration of H+ ions in the blood to increase, causing acidosis in fish. It also causes the function of many enzymes in the fish as well as the function of haemoglobin and haemocyanin in transporting oxygen to become impaired, which leads to serious oxygen deprivation in fish.


Acidic water is usually characterized by normal levels of dissolved oxygen in the water, but fish still exhibit symptoms of oxygen deficiency and float to the surface. Acidic water can also lead to a high incidence of fish diseases caused by protozoa. If the pH is too low, between 5 and 6.5 for a long period of time, it will easily lead to a proliferation of methanogens, which will further deteriorate the water and increase the risk to the fish.

 

2. When the PH value is too high, the ionic ammonia NH4+ in the water body is transformed into molecular ammonia NH3, and the toxicity of the water body increases, causing ammonia poisoning in fish. In addition, when the culture water body shows strong alkalinity, the salinity will also corrode the gill tissue of fish, leading to breathing difficulties and even suffocation and death of fish.


Moreover, too high PH value will affect the activity of microorganisms in the water body and their degradation of organic matter, and will also affect the recycling and reabsorption of substances in the water body.


3. The effect of pH on fish reproduction. When the pH is not suitable, the gonads of the parent fish will be stunted. If the pH is below 6.4 or above 9.4 for a long time, the fry will not hatch. If the pH is too low, the egg membrane can soften, the egg ball collapses and loses elasticity, making it very easy for the membrane to break early during hatching. Therefore, it is important to pay close attention to changes in the pH of the water during the breeding stage.



Therefore the use of water PH sensors for timely monitoring of water PH makes it easier for farmers to take timely measures to adjust the PH of the water, improve production and avoid losses.

The working principle of carbon dioxide detector

图片
The working principle of carbon dioxide detector The working principle of the CO2 detector is mainly based on the infrared light source absorption principle. The following is the detailed working mechanism: Infrared absorption principle: Carbon dioxide detectors detect carbon dioxide gas in the environment through the absorption properties of infrared light sources. Specifically, carbon dioxide molecules have absorption properties for infrared light of specific wavelengths, especially infrared light with a wavelength of approximately 4.26 microns (4260 nanometre ). Measuring chamber and light source: The gas to be measured is introduced into a measuring chamber with an infrared light source mounted at one end of the chamber and a filter and detector at the other end. The filter allows infrared light of a specific wavelength to pass through, while the detector measures the luminous flux through the chamber. Detector Measurement: The amount of light flux received by the detector depends...

Introduction of temperature and humidity data recorder A temperature and humidity data logger is a device used to monitor and record changes in temperature and humidity in the environment. It has an important role in many areas, such as: In the laboratory, it can ensure that the experiment is carried out under the appropriate temperature and humidity conditions to ensure the accuracy of the experimental results. In the storage place, it helps the management to monitor the temperature and humidity inside the warehouse to prevent the goods from getting damp or mildew. In the production workshop, the temperature and humidity of the production environment can be monitored to ensure the normal progress of the production process. Type of temperature and humidity data logger Digital temperature and humidity recorder Features: The temperature and humidity data in the environment is collected by the sensor and displayed in digital form. This type is more common, simple and intuitive operation,...

Weather Forecasting

图片
  The Importance of Weather Forecasting Weather forecasting has an extremely important impact on our daily lives, economic activities and social security. The following are some of the main aspects: 1. Prevention of natural disasters Weather forecasts can predict possible weather disasters in advance, such as heavy rain, typhoons, snowstorms, etc., so as to take appropriate precautions to reduce the loss of life and property.   2. Planning life and production activities People can understand the future weather changes through the forecast, reasonable planning of travel, tourism, outdoor activities, etc., to improve the convenience and safety of life. For agricultural production, weather forecasts can provide farmers with references for agricultural activities such as sowing, fertile  application, irrigation, etc., so as to improve the efficiency of agricultural production and yield.   3. Emergency response When emergencies occur, such as epidemics, earthquakes, etc.,...
