| Good Practices: |
Prolong exposure to the stress of low concentration of oxygen lowers their resistance to disease and inhibits their growth. |
| Bad Practices: |
Oxygen levels also may be reduced when there are too many bacteria or algae in water. Check algal growth. |
| Suggestions Given: |
|
| At night, on days without sunlight or with overcast weather and rain, water will not have enough dissolved oxygen for shrimp. At this time, dissolved oxygen should be increased by using paddlewheel aerator, aeration blower, or partial water exchange |

| Good Practices: |
Water with pH ranging from 7.5 to 9.0 are generally regarded as suitable for shrimp production.Water of excessive alkalinity (pH values > 9.5) may also be harmful to shrimp growth and survival.High ph leads to high plankton growth effects DO in water |
| Bad Practices: |
The increase in pH transforms the ammonium ion (NH4+) into ammonia gas (NH3), which increases the concentration of toxic ammonia in the water. The pH is therefore a determining factor in the risk of ammonia poisoning of fish and shrimp. |
| Suggestions Given: |
|
| The growth of shrimps is retarded if pH falls below 5.0.Water with low pH can be corrected by adding lime to neutralize the acidity. |

| Good Practices: |
hardness is a crucial parameter in maintaining good pond balance. Water alkalinity and hardness can be enhanced by liming ponds. Lime can be used to reduce the acidity in water. |
| Bad Practices: |
0 - 75- Soft
75 - 150-Moderately hard
150 - 300-Hard
Above 300 -Very hard
|
| Suggestions Given: |
|
| In case the water pH fluctuates greatly during the day, lime can also be used to increase alkalinity in the water to stabilize the water pH. However, there is no practical way to reduce alkalinity and hardness. |

| Good Practices: |
Alkalinity Importance:Alkalinity levels for aquaculture are in the range of 50 - 300 ppm CaCO3, which provide a good stabilising effect to pH swings. |
| Bad Practices: |
Total alkalinity has been traditionally expressed as milligrams per liter (ppm) of equivalent calcium carbonate (CaCO3). |
| Suggestions Given: |
|
| Low alkalinity in freshwater or in low salinity areas will affect the survival rate and molting of shrimp. |

the inorganic salts and small amounts of organic matter present in solution in water. The principal constituents are usually calcium, magnesium, sodium, and potassium cations and carbonate, hydrogencarbonate, chloride, sulfate, and nitrate |
| Bad Practices: |
TDS concentrations are often reported in parts per million. Water TDS concentrations can be determined using a digital meter. |
| Suggestions Given: |
|
| Total dissolved solids is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular suspended form. |

| Good Practices: |
Impact of water Quality in Vannamei culture:Outside the optimum ranges, shrimp will exhibit poor growth, erratic behaviour, and disease symptoms or parasite infestations. Under extreme cases, it leads to death of shrimps |
| Bad Practices: |
Water quality problems resulting from high stocking,
increased feeding rates and intake of polluted water are
increasingly common in shrimp farming. Good water quality directly influences shrimp growth, survival and overall production. |
| Suggestions Given: |
|
| Regular water check ups |

| Good Practices: |
Ammonia is toxic to L vannamei because high concentrations can damage the gill, hepatopancreas and possibly the gut lining. This will damage – such as respiration, metabolism, immunity, osmotic regulation, nutrient absorption & moulting. |
| Bad Practices: |
Low levels of ammonia 0.03 mg/1 (PPM) or less are not harmful to shrimp or fish, any level above is considered harmful |
| Suggestions Given: |
|
| Increasing pond aeration or the process of removing dissolved gases is another way of decreasing ammonia concentration |

| Good Practices: |
Nitrogen fertilizers such as urea or ammonium nitrate can be applied to ponds to stimulate phytoplankton growth and increase the natural food base for fish or shrimp production. |
| Bad Practices: |
Nitrite also can be toxic to aquatic animals, for it is absorbed and interferes with the ability of blood to transport oxygen. |
| Suggestions Given: |
|
| Increasing pond aeration or the process of removing dissolved gases is another way of decreasing ammonia concentration in a fish pond. In a small scale pond, aerating will remove the dissolved toxic ammonia through diffusion from water into the air. |

| Good Practices: |
Water temperature plays a very important role in regulating the activities of the cultured animal. The rate of chemical and biological reactions is said to double every 10°C increase in temperature. |
| Bad Practices: |
The optimum temperature is about 25–30°C |
| Suggestions Given: |
|
| aquatic organisms will use twice as much dissolved oxygen and chemical reactions will progress twice as fast at 30°C than 20°C. It follows therefore that dissolved oxygen requirement of aquatic species is higher in warmer than in cooler water. |

| Good Practices: |
Partial harvesting is useful in some types of management systems where only large shrimp are to be caught and smaller shrimp left in the pond to grow larger, |
| Bad Practices: |
Sampling is compulsory before harvesting |
| Suggestions Given: |
|
| Shrimps move around the pond at night looking for food. They are attracted to light. They are stimulated by movement of water. When water is let into a pond, the shrimp become active, swimming around the pond and often gathering near the sluice gate. |
