1. What is the molting process of shrimp?

Like other crustaceans, shrimp possess a chitin outer shell that can affect their development and increase their size. Therefore, they need to molt and completely renew their shell. This molting process usually takes place through many stages.

Many people wonder, during a shrimp’s life cycle, how does the peeling cycle take place? According to experts in the field of aquaculture, shrimp peeling time is from 10pm to 3am, most happening from 1am to 3am. As for healthy shrimp, the peeling time takes place extremely quickly in just 5 to 7 minutes. As for shrimps with weak health, the peeling time lasts longer from 1 hour to 2 hours or even from 1 day to 2 days. According to statistics, the molting cycle of shrimp includes 3 stages:

• Pre-molt: At this stage, shrimp will exercise little
• Molting: They often molt at high tide or on full moon days.
• After molting: Farmers need to supplement shrimp with essential minerals so that the shell hardens quickly.

2. Why is it necessary to stimulate shrimp to peel?

The peeling process plays an important role inprocessshrimp growth. Each time the shrimp’s shell and body are peeledwillgrows rapidly to a larger size than the old shell. This helps shrimp grow quicklybothsizeconfusedvolume.

However, under natural conditions, the molting process of shrimp does not always take place regularly,especiallywhen encountering unfavorable environmental conditions. Therefore, stimulating shrimp to molt at the right time will optimize the growth process, helping shrimp reach commercial size faster.contributeImprove economic efficiency for farmers.

On the other hand, stimulating shrimp to peel at the right time will improve the health quality of shrimp. During the peeling process, shrimpwillRemove old bark that is damaged, dirty or infected. The formation of a new shell will help protect shrimp better against pathogens in the pond environment.

In addition, shrimp may have difficulty if they do not peel properly. This is possiblemake themPhysiological stress, increasing mortality or reducing resistance. Therefore, controlling and stimulating shrimp to peel is extremely necessary.

3. What factors affect the molting process of shrimp?

Peeling is the natural growth mechanism of shrimp, but they cannot always peel their shells successfully. In some cases, shrimp cannot peel or easily dieor sufferdamage after peeling. Accordingly, whether the shrimp peeling process goes smoothly or not depends on the following basic factors:

• Nutrition: Deficiency of minerals such as calcium and phosphorus can cause the peel after peeling to become soft and not harden quickly.
• Water temperature: Low temperatures will slow down metabolism, causing shrimp to peel more slowly. On the contrary, high temperatures stimulate metabolism, causing shrimp to peel faster.

Temperature greatly affects the shrimp peeling process

• Water salinity: Appropriate salinity helps shrimp absorb minerals better, and the shell quickly hardens after peeling. Low salinitybelow the allowable levelwill reduce the amount of minerals that shrimp absorbs, affecting the quality of the shell after peeling.
• Shrimp hormones: The molting hormone ecdysone controls the molting process of shrimp. If shrimp have a hormone deficiency, the molting process may be delayed or occur unevenly.
• Shrimp are stressed, high density: When shrimp are stressed, their immune systemsufferweakened, reducing the ability to peel successfully. In addition, when the stocking density is too high, movement space is limited and the shrimpwillcompete for food sources, slowing down the growth and molting process.

4. Solution to help shrimp peel quickly, evenly and healthily

To ensure farmed shrimpreachedHigh productivity, big and strong, farmers needapply measuresStimulates shrimp to peel simultaneously and at the right timefollowing:

4.1 Adjust salinity in shrimp farming water

Salinity is one of the important factors that directly affects the peeling process of shrimp. Farmers need to check the salinity of pond water regularly, at least once a week, using a salinity meter or electrolyte meter. If the salinity is found to be inappropriate, the farmer canAdjust by the following measures:

Adjusting the salinity in shrimp water helps shrimp easily absorb minerals to peel their shells

• When salinity is too low:Add salt water to the pond to increase salt concentration. Salt water can be obtained from natural sea water sources or using diluted sea salt. However, care should be taken to add slowly and not increase suddenly to avoid shocking the shrimp.
• When salinity is too high:Farmers should add fresh water to dilute the pond water. This process also needs to be done slowly so that the salinity gradually decreases, avoiding stress to the shrimp due to changing the environment too quickly.

4.2 Control pH in ponds

In shrimp ponds, pH directly affects the metabolism and physiological processes of shrimp, especially the peeling process. To control pH in the pond, you can use lime to raise pH as well as provide additional minerals needed for shrimp. There are 2 types of lime that can be used:

• Agricultural lime (CaCO₃): Often used to increase alkalinity without causing sudden changes in pH. This lime is suitable for long-term alkalinity correction.
• Slaked lime (Ca(OH)₂): Has a quick effect in raising pH, but needs to be used with caution to avoid increasing pH too high.

Note: Farmers should add lime to ponds in appropriate doses, usually about 10-20 kg/1,000 m³ of water, depending on the specific condition of the pond.

4.3 Change water periodically

Changing water is a measure to help remove toxic substances accumulated in the pondaimImprove water quality, support shrimp to peel quickly and simultaneously. Farmers should change water periodically, about 30 – 40% of the water volumeinpond every week, depending on environmental conditions and pollution level of the pond. This is a popular and simple method. Change the water in the pond to gently stimulate the shrimp to peel, then run a fan to aerate the water.

In addition, the addition of clean water to the pondwillProvides additional natural minerals from the water source, helping to support the shrimp peeling processmore effective.

Regularly changing the water for shrimp ponds also has the effect of stimulating shrimp to peel

Maintain stable pond water environmental factors: Sudden changes in temperature, pH, salinity, and dissolved oxygen can shock and stress shrimp, hindering the molting process.

• Temperature: Controls water temperature at a steady level.
• pH and alkalinity: Add lime when it rains to maintain pH and alkalinity, making it easier for shrimp to peel.
• Dissolved Oxygen: Ensures dissolved oxygen levels remain high. Run a water fan to increase oxygen and remove toxic gases.

4.4 Control your diet

Providing nutritious food in sufficient amounts will help the shedding processof shrimptake place evenly and effectively. Farmers should feed shrimp foods rich in protein (containing about 30 – 40%), lipids, vitamins and necessary minerals.

During the period before and after molting, shrimp needs more nutrients to support the process of regenerating new shells. Therefore, the breederrightIncrease food intake and mineral supplements during these times. However, avoid increasing too much because it can lead to excess and pollute the shrimp’s living environment.

• Choose the right food: Use high-quality industrial food that is easy to digest and rich in protein to provide enough energy for shrimp during the molting period.
• Nutritional boost: Vitamins, minerals, and enzymes can be mixed into food to enhance health and aid in the shedding process.

4.5 Use biological products to control bacteria

Using probiotics is a safe and optimal solution to help shrimp peel simultaneously and is applied by many people.On the other hand, this solutionIt also has a positive impact on the shrimp’s living environment such as improving water quality and enhancing shrimp resistance.

Besides the above solutions, farmers can also consider other ways such as adjusting alkalinity, temperature or adding minerals to create the best conditions for the shrimp peeling process.

4.6 Supplementing minerals helps shrimp peel quickly

• Periodic supplementation: Shrimp need to absorb minerals, especially calcium, magnesium, potassium and zinc, from the water environment to create new shells.
• Supplement time: Add minerals at night, when shrimp molt a lot, to ensure shrimp has enough materials to harden their shells quickly.
• Use specialized products: You can use specialized mineral products or organic minerals to make it easier for shrimp to absorb.

5. Important notes when stimulating shrimp to peel

Stimulating shrimp peeling is a necessary step in the aquaculture process. However, to ensure safety, effectiveness, and no harm to farmed shrimp, farmers need to pay attention to the following issues when stimulating shrimp to molt:

• Regularly check water samples in the pond to determine which molting stage the shrimp are in. In particular, you must record exactly the times they molt. That helps us predict future molts more accurately.
• During the shrimp molting process, you must control the amount of dissolved oxygen in the pond at 4 to 6 mg/liter. To ensure sufficient and stable oxygen levels, farmers should run fans or aerate the pond. The pH also needs to reach 7.5 to 8.5.
• Increase aeration at night when shrimp molt, don’t forget to use Bio Active to remove toxic H2S gas in the pond,
• In principle, after shrimp molt, the water in the pond will decrease in alkalinity because ions are used to create new shells for them. If so, you need to adjust the alkalinity back to 100 to 200 ppm
• If the weather is rainy or heavy, the molting process of shrimp will take place unevenly due to lack of oxygen in the water in the pond and increased levels of toxic gases. In that case, people should use limeMaintaining pH and adding probiotics will help prevent shrimp from molting and control toxic gases in the pond.
• Reduce stress: Avoid strong impacts that stress shrimp, such as loud noises or sudden environmental changes.
• Disease prevention: After peeling shrimp, it is very weak and susceptible to disease. It is necessary to maintain a clean environment and control pathogens to avoid loss.
• Observe shrimp: Monitor shrimp regularly to recognize signs of preparation for molting such as loss of appetite and loose shells, so that you can take timely support measures.
