What are the precautions for breeding mantis shrimp? What conditions should be met for breeding mantis shrimp?

Gobies have the habit of digging sand, so when planting water plants, you should pay attention to planting water plants with relatively strong roots. In addition, it is best to arrange a place for gobies to hide in the tank to facilitate their breeding and laying eggs. In the tank where gobies are raised, it is best to keep the water flowing smoothly and the water temperature should not be too high, so that the body color of the gobies will be more colorful. Make sure there is enough food to prevent them from attacking other small fish or shrimps. It is best to breed gobies in a single tank and a single pair, so as to ensure a higher hatching rate. The environment with a nest hole at the bottom of the tank is better with some plants. The sunlight should not be too strong. The water body should be plant-humus water, and the pH value should be around 6.5. During the hatching period, the broodstock will stop eating to protect the eggs. After the fry come out, they should be fed with live bait. Some equipment for breeding brine shrimps should be prepared in advance. Of course, if there are no conditions, red nematodes or water earthworms can be crushed manually for feeding, so that both large and small fish can eat them.

That's all I can think of. I didn't breed them professionally before. They were all thrown into a big tank. The reproduction method of shrimp goby is different from that of other fish species. It is oviparous. When it comes to the hatching period, shrimp goby will go to gravel or caves in groups to lay eggs, most of which are sticky eggs. Soon after hatching, they will become larvae, and then wander in the sea for three weeks, looking for a coral reef to live in, where they will reproduce. To raise tiger shrimp, you must first clean the pond and disinfect it. New ponds should be soaked in moisture-proof water as soon as possible, and disinfect after the HP value in the pond is stable. For old ponds, seal the gates and dry the ponds after collecting shrimp, remove dirt, and then disinfect.

After the shrimp pond is disinfected and sterilized for 2 to 3 days, water can be infiltrated and fertilized. To make basic fish bait, basal fertilizer, phosphorus-potassium fertilizer and organic fertilizer are generally invested. The ratio of basal fertilizer and phosphorus-potassium fertilizer is 3:1 or 3:2. 3 to 3 grams of water should be used for each meal. Fertilizer should be applied once every three to five days in the early stage and once every seven to ten days in the middle and late stages. The water clarity is best between 25 and 30 cm. The water should remain light yellow or light brown. The free-range breeding time is based on the temperature. It cannot be released after hot weather or heavy rain. The temperature and salt content of the shrimp pond must be checked before releasing the seedlings. If the temperature of the water is too different, the plastic bag containing the shrimp seedlings can be put into the water immediately, and the seedlings can be released after the water temperature is balanced. If the salt difference is too large, the water of the breeding fish pond can be poured into the shrimp bag, and then drained after a while, and then poured in again, and the shrimps can be gradually absorbed into the water in the pond before releasing the seedlings.

The most suitable salt content for tiger prawns is 12‰, while the salt content of shrimp fry in the early stage of cultivation is around 30‰. Therefore, the salt content of the water surface for free-range cultivation should be similar to that of the shrimp fry pond. After free-range cultivation, water can be gradually added to reduce the salt content to an appropriate range. Therefore, it is extremely important to have good water resources and sound drainage facilities. It is best to have a water resource (including surface water) in the shrimp farming area without large rivers and streams. Tiger prawns can tolerate water temperatures of around 10-35℃, and the suitable ambient temperature is 25-30℃. If the water environment temperature changes too much during the cultivation period, surface water can be extracted for grouting in a short period of time. If the water temperature is within 20℃ for a long time and there is no strong wind and waves, the water level can be lowered and the solar energy can be used to increase the ambient temperature; if the water temperature is too high, the water level can be raised or surface water can be introduced.

You need to choose a suitable breeding environment, pay attention to the water density and oxygen content, and breed at a temperature above 10°C.

It has strict requirements for the environment in which it grows. It is necessary to choose a place with sufficient water and very good water. It is best if the pond is made of cement. There are also requirements for the size and oxygen content in the water. The water should be changed every day to ensure that the water is clear and the water temperature should be controlled. Mantis shrimps are active at night, so you should feed them more food in the evening and less food during the day because they are generally not active during the day. When feeding, you can choose some small fish, shrimps or shellfish. Don't put in large pieces. Cut the bait into smaller pieces to ensure that it is evenly distributed. You should also feed more to prevent the mantis shrimps from competing for food and killing each other.

We need to pay attention to the temperature of the fish, the diet, the breeding process, disease prevention, soil, and water quality. We need to have a very good filtration system, and be able to frequently replace the water source with pharmaceutical preparations. There should be no toxins or harmful substances in the water source, and we should also pay attention to the presence of microorganisms.

Mantis shrimp is a very common delicacy, so what are the methods for breeding mantis shrimp?

The dissolved oxygen in the water is kept above 5mL/L, 1/4 to 1/3 of the water is changed every day, and the transparency is between 30 and 50cm. Mantis is a ferocious endothermic crustacean, and its growth and life activities are directly affected by the ambient water temperature. The water temperature in its living area is about 6 to 31°C, and the optimal temperature is 20 to 27°C. It is a warm-blooded species. Under laboratory conditions, when mantis is moved directly from 17°C to 5°C seawater, its body immediately arches, slowly straightens, and then falls into a coma.

After moving it to 33℃ seawater, the mantis first jumped up and down, then fell to one side of the bottom, with only the swimming limbs able to swing, and fell into a coma after 3 minutes. Therefore, it can be considered that its temperature range is 5~33℃. When the water temperature changes, the temperature range will increase. Water quality management: The water body should maintain a dissolved oxygen content of more than 5ml/L, a daily water change of 1/4-1/3, a transparency of 30-50 cm, a water temperature of approximately 6-31℃, and an optimal temperature of 20-27℃. Feed management: Feed once every night, with a feed amount of 5%-20% of the shrimp weight. Daily management. During the hatching period, it is necessary to patrol the pond to check the inlet and outlet, the activity and feeding of the shrimp, the water quality and the discharge of the larvae.

Water quality management is very important for shrimp farming, and it is related to the success or failure of shrimp farming. Under normal circumstances, the oxygen content of shrimp farming water should be kept above 5ml/L, and the water should be changed every day, with the amount of water changed controlled at 1/3 or 1/4 each time. If aquaculture can be adopted, water can be omitted. In addition, the water temperature should be paid attention to. Generally, it is best to keep it around 20 to 27 degrees, with the minimum temperature not lower than 6 degrees and the maximum temperature not higher than 30 degrees.

There are artificial breeding methods, river breeding methods, indoor breeding methods and outdoor breeding methods. When breeding mantis shrimp, you must pay attention to temperature issues, environmental issues, water quality issues, feed issues, and safety issues. Because when breeding mantis shrimp, you cannot let the mantis shrimp grow in a very poor environment, and you cannot let yourself get hurt.

First of all, you should choose a suitable farm, then you should also choose higher-quality varieties and some nutritious bait. Then you should also pay attention to the number and frequency of feeding. Don't feed too much. Then you should also change the water source regularly, remove weeds in the water, ensure that there is sufficient oxygen in the water, and prevent diseases.

Pay attention to seed selection, feed management, seedling cultivation, water quality management, and be sure to pay attention to the development of seedlings.
