| 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 sun light 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 paddle wheel 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 effectsDO 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 shrimp is retarded if pH falls below 5.0 water with low pH can be corrected by adding lime to neutralize the acidity. |

| Good Practices: |
Aeration:one to three single horse power paddle wheel aerators are usually used,depending on farm size and stocking densities.The aerator typically operate for 8-12hours per day during the entire culture period.Aerators are placed 3m away from dykes |
| Bad Practices: |
Mortality if shrimp seed occurs due to bad handing during transport
Bad management practices like inadequate nutrition,poirwater quality maintenance were correlated with the incidence of loose shell syndrome in L.Vannamei |
| Suggestions Given: |
|
| Water &soil treatments:After stocking,probiotics,minerals, zeolites, ammonia reducer compounds, dissolved oxygen(DO) engancer compounds and disinfectants are widely used at regular intervals. |

| 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 litre (ppm) of equivalent calcium carbonate (CaCO3). |
| Suggestions Given: |
|
| Low Alkalinity in freshwater or in low salinity areas will affect survival rate and molting of shrimp. |

| Good Practices: |
Take shrimp samples regularly: sampling allows farmers to understand shrimp growth & adjust the feed regime, preventing over feeding & under feeding.It is recommended to take shrimp samples every 5 to 7 days using nets.aporopriate to the current size |
| Bad Practices: |
Avoid sampling near the feed trays because the shrimp there tend to be bigger than the rest.Avoidvsampking when the shrimp are moulting. |
| Suggestions Given: |
|
| Take random samples vertically covering the top,middle and bottom of the water column-as well as horizontally, covering various sides of the pond sampling is done to estimate the MBW, whichbis calculated by dividing the total weight by theNo.ofShrimp |

| Good Practices: |
Above optimum range shrimp will exhibit poor growth,erratic behaviour,and disease symptoms or parasite infections.Under extreme cases,or where the poor conditions remain for prolonged periods of time,shrimp mortality may occur. |
| Bad Practices: |
Frequent water quality check up is suggested. |
| Suggestions Given: |
|
| The composition of pond water changes continuously, depending on climatic and seasonal changes,and on how a pond is used.It is the aim of good management to control the composition to yield the best conditions for the shrimp. |

| Good Practices: |
Ammonia is toxic to L.Vannamei because high concentrations can damage the gill, hepantopancreas and possibly the gut lining.This will damage-such as respiration, metabolism, immunity, osmotic regulation, nutrient absorption & moulting. |
| Bad Practices: |
Low levels of ammonia 0.03mg/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: |
Nitrate 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 10c 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 30c than 20c . it fallows 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. |
