If you want to raise lobsters, I don t know which kind of lobster is good to raise, and whether lobs

There is only one lobster species in China, and the key is to choose the seedlings when choosing uniform size, strong activity, and no injuries.

It's not something that can be said clearly in one sentence or two. A brief summary is as follows. You can refer to the following:

The first is to create a good environment for lobster growth. Lobsters are insect shells, similar to crabs, with a pair of particularly developed chelae, and have the habit of burrowing, generally digging burrows near the water's edge. Lobsters are shady and afraid of light, crawling out of burrows when the light is weak or dark, and sinking to the bottom or hiding in burrows when the light is strong.

According to the habits of lobsters, a 50 cm high escape net can be added to the river pond to prevent lobsters from escaping. At the same time, the river pond simulates the ecological environment of lobsters under natural conditions, and 10-15% of aquatic weeds and hidden objects are planted shallow on the edge of the pond to create an environment for lobsters to inhabit and shell, and reduce mutual killing.

The impact of water quality on lobster production cannot be ignored. The quality of water quality directly affects the healthy growth and development of lobsters, during the breeding process, the pH value of the pool water is kept between, the transparency is 30-40 cm, new water should be added frequently, and quicklime solution should be splashed regularly, and the water quality should be adjusted to prevent diseases and shelling.

The second is to feed reasonably. Lobsters can kill each other when they are hungry and underfed, so the amount of feed must be sufficient. The feed of lobsters is animal and plant feed.

The plant-based feed is wheat, aquatic weeds, rapeseed cake, etc., and the animal-based feed is trash fish, miscellaneous meat and offal. Usually according to the lobster's diurnal and nocturnal habits and the density of shrimp in the pond to determine the feeding time, feeding amount and feeding method. Otherwise, it will increase the cost of feed and reduce the efficiency of breeding.

The third is scientific fishing. In the process of lobster farming, juvenile shrimp can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings are released in March, and the rotation fishing begins around June, and the big ones are sold and the small ones are kept.

Due to the large catch and small retention, round fishing and release, it can improve the recapture rate, sell at a good price, and achieve the purpose of high yield and high efficiency.

Crayfish is relatively easy to raise, this animal reproduces relatively quickly, for the bait is not picky, can be cultivated together with rice, as long as the construction of the site, the delivery of shrimp species and the supervision of water quality, etc., can be selected in the old rice field breeding, 40 kg of shrimp seedlings per acre, planting aquatic weeds can be regularly inspected.

1. Easy to raise

Crayfish is relatively easy to raise, this animal in the wild without natural enemies will even flood, it can be seen that they reproduce fast and tenacious vitality, and crayfish farming generally does not need a special site, can be cultivated in the rice field, and rice symbiosis, saving the site at the same time can also purify the water quality.

2. Site construction

Crayfish can be remodeled from ordinary rice fields. Choose a rice field close to the water source with good and clean water quality and abundant water, and then add high ridges to strengthen the embankment, it is best to add fine nets to the ridges on all sides to prevent lobsters from escaping, and install fine nets at the inlets and outlets, and make fences to prevent shrimp from escaping.

3. Shrimp seed stocking

Before putting shrimp seeds, you need to plant some elophyte or water peanuts in the reconstructed rice field, and add a certain amount of fertilizer to play the role of fertilizing the field, the density of algae should not be too large, and the seeds should be planted when the weather is relatively sunny and cool, so as to reduce the mortality rate of lobsters, and 40 kg of shrimp seeds can be put into each acre.

4. Regular inspections

Crayfish feed on plankton in the water body in the early stage, and the bait that is fed by blind in the later stage is mainly based on various proteins and concentrate feed, and animal offal or flesh can also be added, but it is necessary to take the initiative to inspect regularly, salvage the leftover food residues, regularly change the water and increase oxygen, observe the growth and development of crayfish and make adjustments.

There are many lobster breeding bases in Hubei, Hunan, Chongqing, Zhejiang and Jiangsu.

In our country, most of the areas have lobster breeding bases, including Hubei, Hunan, Chongqing, Zhejiang and Jiangsu and other regions of the lobster breeding base more, it is recommended to contact in advance and then go to the breeding base for field investigations, lobster adaptability is wider, its fecundity is stronger, whether it is rice fields, ponds, rivers or lakes, can be farmed.

Lobster adaptability is very wide, strong reproductive ability, in lakes, rice fields, rivers and ponds can be farmed, its pond culture, easy to manage, feed is very wide, the yield is also high, is a common lobster farming method. Build a pond: the pond area is about 10 acres is the best, the water depth is about 1m, the pond silt is about 5cm, dig a deep and wide shrimp collection ditch at the bottom of the pond, and also need to set up anti-escape facilities around the pond.

Key points for raising crayfish in summer

1.Strengthen water quality management

The temperature in summer is relatively high, so farmers must strengthen the management of water quality, in the hot environment static water temperature is easy to rise, will seriously reduce the oxygen content, can take measures to increase oxygen according to the specific situation, at the same time in summer to properly deepen the water level, to avoid direct sunlight to increase the water temperature.

2.Feeding management

Summer crayfish must pay attention to the best in the early morning and evening when the temperature is relatively low, because the temperature at noon will also affect the appetite of the crayfish, affect the crayfish to eat, the feed is best to be higher in protein, which helps to improve the high temperature resistance of the crayfish.

3.Polyculture with aquatic weeds

When breeding crayfish, it is best to polyculture with aquatic weeds, and proper breeding of some aquatic weeds can not only improve water quality and maintain the water environment. And in the summer, aquatic plants can also shade crayfish from the sun and maintain the temperature of the water body, but farmers should also manage aquatic weeds, the growth size of aquatic weeds should not be too high or too low, and aquatic weeds should show a slag silver dot distribution, so as to play a role in the effect of crayfish to escape the heat, such as blocking the feast.

4.The key points of daily management and balance of the world

Due to the high temperature in summer, crayfish like to stay in the diving position at night to breathe, at this time crayfish are likely to become the object of predation of predators, farmers must patrol the pond more. In addition, the feed residue in the pond is easy to spoil in summer, leading to crayfish infection, so farmers must pay more attention to the condition of the pond.
