Six parameters for water quality monitoring

pH

| Hydrogen ion concentration index,

reflecting the acidity and alkalinity of water bodies; Various organisms have their most suitable pH range; High pH water has a corrosive effect on gill tissue;

Low pH values can lead to the proliferation of pathogenic

bacteria and increase the toxicity of hydrogen sulphide;

| ****

6.5~7.5 (Dragon fish tank) 7.5~8.2 (seawater fish tank)

ORP

| Refers to the redox capacity of water bodies, which refers to the total potential of water bodies;

Generally, aquaculture ponds require an increase in redox potential;

Low ORP  will provide conditions  for the accumulation  of

toxic  substances  such  as ammonia  nitrogen, nitrite, and

| ****

350-450mv (seawater fish tank)

 | hydrogen sulphide;|
---|---|---

EC

| Refers to the concentration of soluble salts in the solution or the concentration of soluble ions in liquid fertilizers or planting media;

As an indicator to ensure the health of the ocean and its living organisms, it is often used in conjunction with salinity;

The higher the conductivity value, the better the conductivity. The more impurities, the worse the water

quality;

| ****

<2000us/cm (fresh water) 45000uS/cm~SS000uS/cm (Seawater fish tank)

Salinity

| Refers to the amount of salt that has been appropriately dissolved in the water body, determining the suitable species of aquatic animals;

And salinity can affect the solubility of dissolved oxygen, which is crucial for water quality;

The optimal salinity can increase the body’s food intake and enhance the body’s epidemic prevention mechanism; Low salinity can lead to increased weight and mortality of

marine organisms;

| ****

1.021-1.025 (seawater fish tank)

DO

| Molecular oxygen dissolved in water directly affects the metabolic intensity of fish and shrimp, thereby affecting their growth;

Generally, it is inversely proportional to  water temperature and salinity, and directly proportional to atmospheric pressure;

It is necessary to ensure sufficient oxygen supply in the aquaculture environment. High dissolved oxygen is conducive to the degradation of various pollutants in the water body, thus enabling the water to be purified quickly.

However,  if  it  is too  high, it  can  cause  fish  to develop

| ****

5~8mg/L

 | bubble disease;

Low indicators lead to slow degradation of pollutants and hypoxia in cultured animals;

|
---|---|---

Temperature

| Temperature is the most important factor affecting animal growth rate, digestion and absorption;

Different organisms have different requirements for water temperature;

Within    the  optimal   temperature     range, fish exhibit vigorous feeding, respiratory, and digestive functions, enhanced metabolic  function, and rapid growth; Exceeding the appropriate temperature  range can lead to

metabolic  dysfunction, growth inhibition, and even death;
