Anonymous users2024-02-13When raising crayfish, it is necessary to control the feeding density, because the crayfish has a strong sense of territory, and the density is too large and it is easy to fight and get injured. It is also necessary to establish a good ecological environment for crayfish, and bottom sand, sunken wood, and aquatic weeds are all necessary. You can feed crayfish with bloodworms, prawns, vegetables, etc., and pay attention to salvage residual food and feces to avoid polluting water quality.
How to raise crayfish.
1. Pay attention to density.
How to raise crayfish, maintenance methods and skills of crayfish.
Before raising crayfish, it is necessary to first choose a good shrimp tank, and plan the density of rearing, as well as whether to polyculture other ornamental shrimp. Crayfish is a more aggressive ornamental shrimp, crayfish has a strong sense of territory, if you don't want to raise your own crayfish often fight and get injured, it is best to reduce the breeding density.
2. Landscaping in the cylinder.
How to raise crayfish, maintenance methods and skills of crayfish.
Establishing a good ecological environment is a very important point for raising crayfish, crayfish like to live on sand and gravel, so the bottom sand should be laid in the shrimp tank, and the bottom can be paved with an appropriate amount of maifan stone, coral sand and other materials. It is also necessary to put in sunken wood, stones, aquatic plants, etc., to provide a place for crayfish to hide and feed. It should also be paired with water plant lamps to enhance their absorption of trace elements.
3. Reasonable feeding.
How to raise crayfish, maintenance methods and skills of crayfish.
The foods that can be eaten by crayfish are bloodworms, vegetables, harvest shrimp, etc., which are highly nutritious and can be used as the staple food of crayfish, so that crayfish grow faster and more robust. Celery stalks are generally recommended for vegetables, and spinach leaves can also be fed, but they are easy to pollute water quality and are not easy to clean.
4. Regular maintenance.
How to raise crayfish, maintenance methods and skills of crayfish.
It is very important to change the water regularly and clean the filtration system, we must pay attention to the water quality when raising crayfish, and regularly clean up the residual food in the shrimp tank.

Anonymous users2024-02-12Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: Can you raise crayfish without oxygen:
Raising crayfish can be without oxygen, if the tank is large, you don't need oxygen, if the tank is small, you still have to use oxygen. Because the head of the crayfish can accumulate a small amount of water, there should be no problem within 24 hours of leaving the water. So whether oxygen is needed or not is basically necessary, but there are also the following:
1. The water level is relatively shallow, and the crayfish can leak out of the water when standing by the tank, and there is no need for an oxygen pump. 2. High-speed flowing circulating water. During the period when the crayfish is about to be shelled, the shrimp eats smaller, the body color becomes darker, and the most protruding shrimp head is obviously isolated from the body.

Anonymous users2024-02-11White shrimp is a relatively easy species of ornamental shrimp to raise, because they have a strong ability to survive, the requirements for the environment are not strict, and they can adapt to a variety of environments. When farming, they can be fed by using a slightly larger tank and using neutral fresh water as the breeding water. They are omnivorous and can eat a variety of foods such as vegetables, small fish and shrimp, aquatic insects, shrimp food and fish food, so they are also relatively easy to feed.
1. Water temperature: White shrimp has a certain adaptability to water temperature, and can grow in water from 15 to 28. However, they cannot adapt to sudden changes in water temperature in a short period of time. Attention should be paid to maintaining a stable water temperature during breeding, so as to avoid sudden changes in water temperature and discomfort caused by shrimp.
3. Feeding: Compared with other ornamental shrimp, their food consumption is relatively large, so it is recommended to feed 1-2 times a day. If you are raising shrimp that have just been born, you can also increase the frequency of feeding. The feed is recommended to choose shrimp food from crayfish, or clean bloodworms.

Anonymous users2024-02-101. The water quality requirements are appropriate
Shrimp are aquatic animals, so water quality is very important for shrimp farming. The best water quality for crayfish farming is acidic or neutral water quality orange source, the pH value is generally between, and the water temperature is controlled at about 18 is more suitable.
In addition, crayfish need to have enough oxygen to breathe. When farming, it is necessary to change the water regularly to keep the water clean.
2. Choose a suitable breeding environment
Crayfish farming requires a suitable environment. For example, proper light can promote the growth of crayfish, and the breeding site should be full of sunlight and not too long. In addition, the habitat of the crayfish needs to have enough space to place some benthic habitats, such as stones and plants, that can provide perch and food.
In addition, it is necessary to pay attention to the permeability of the environment where the crayfish is located, if the soil is too compact, the puddle structure may be poor, so corresponding measures need to be taken.
3. Choose suitable varieties
There are many varieties of crayfish, some of which are relatively easy to farm. The most common are red and white crayfish. It is difficult to breed white-hooked shrimp and requires higher skills and knowledge of aquaculture management, while the characteristics of red-hooked shrimp are favored by farmers such as easy to raise and raise, and fast growth rate.
Therefore, for beginners, farmed crayfish is the most suitable.
4. Scientific and reasonable feeding
Proper feeding is the key to the success of crayfish farming. Crayfish are suitable for eating fish, insect eggs, raw meat, vegetables and other foods.
The amount of bait must be controlled when feeding, and the water quality should not deteriorate due to greed. The amount of each feeding should be limited to the consumption of crayfish, and the type and quality of bait should also be paid attention to, and the food should be fresh and should not be put for a long time. In addition, the types of food and bait in the disadvantageous state of crayfish balls are related to water depth and water temperature, and need to be scientifically and reasonably matched.
Fish or Plexiglass transparent aquariums are ideal for ornamental shrimp feeders. If you need to raise more, you should prepare more aquariums, because it has the habit of eating the same kind, you can't mix more than one, and you can only raise 1 2 per feeder. If you only raise 1 2 crayfish, use a rectangular aquarium of 30 cm * 25 cm. >>>More
At present, the domestic factory shrimp farming model: generally 3 5 stubble shrimp a year, after the seedlings are released, the standard seedling method is adopted to improve the success rate and shorten the breeding time. The first standard seedlings are about 25 days, the second time the seedlings are completed after the first standard seedlings 15 days, and the standard seedlings can be sold for 70 days, which not only improves the breeding efficiency, but also increases our profits. >>>More
Lobsters and crayfish can be polycultured. Although crayfish and lobsters are both crustaceans and shrimps, their species are also different.
