Overview
1. It can meet the needs of aquaculture measurement of various Rivers and Lakes and oceans. It is one of the ideal instruments for modern aquaculture monitoring and management. 2. Easy to operate, simple, and fast, without the need for debugging. Even untrained personnel can quickly master the usage of the instrument.
Product Details
In aquaculture, dissolved oxygen and appropriate pH valueIt is a condition of *. Ammonia nitrogen, nitrite nitrogen, and hydrogen sulfide are the main toxic substances produced by the metabolism of fish and shrimp. Accurately and timely measuring the concentration values of these substances and taking corresponding measures can greatly improve the survival rate of fish and shrimp and reduce breeding costs.

To ensure the normal growth of fish and shrimp, the water quality standards for aquaculture should meet the following standards:
（1）Dissolved oxygen: Like humans, aquatic animals must survive under aerobic conditions. Lack of oxygen can cause them to float, and in severe cases, flooding can lead to death. Generally speaking, the dissolved oxygen in aquaculture (seedling) water should be maintained at 5-8 mg/L, at least 4 mg/L or above, and not less than 3 mg/L. In the later stage of high-density precision breeding, it should not be less than 4 mg/L. In addition, fish and shrimp with high dissolved oxygen are prone to bubble disease.
(2) The pH value is between 6.5-9.0 and not higher than 9.2. Marine aquaculture is between 7.5-8.5, with a daily difference not exceeding 0.5.
(3) The content of ammonia nitrogen (NH3-N) is below 0.6mg/L. The toxicity of ammonia nitrogen is related to the pH value of water. When the pH value is high, ammonia nitrogen can be converted into molecular ammonia that is highly toxic to fish and shrimp, inhibiting their growth, damaging gill tissue, and exacerbating fish diseases. Molecular ammonia can cause acute poisoning and death in aquatic animals at lethal concentrations of 0.2-0.5mg/L. Fish and shrimp may exhibit severe anxiety when experiencing acute ammonia poisoning. Due to the alkaline pH value of the water at this concentration, it has a strong irritant effect, causing an increase in mucus on the surface of fish and shrimp, resulting in surface congestion and significant bleeding at the gill and fin base. Fish swim on the surface of water, with protruding eyeballs and struggling to open their mouths before dying.
(4) The toxicity of nitrite (NO2-N) in shrimp is quite high. Generally, if the content in shrimp ponds exceeds 0.15mg/L, it can cause serious harm. When the concentration of nitrite in water reaches 0.5mg/L, some metabolic functions of fish and shrimp become abnormal, and their physical strength declines. At this time, fish and shrimp are prone to illness, and in many cases, large-scale outbreaks of disease and death occur.
(5) The concentration of hydrogen sulfide should be strictly controlled below 0.1mg/L. When it exceeds 0.5mg/L, it can cause difficulty breathing in fish, shrimp, crabs, and turtles, and even lead to poisoning and death.
