20 19 crayfish market "diving" is widely circulated on the internet, but shrimp farmers complain about it. Not only is the value of crayfish breeding worthless, but even whether crayfish can be raised is worth raising. A series of problems followed, but Xia Bao also wrote the future development trend of crayfish culture, from cheap to fine, from individual concentration to all seasons, which proved that crayfish still has a market in the future.
However, many people are skeptical about this, but some newcomers have asked me, is it risky to raise crayfish? What should I pay attention to when breeding crayfish?
Today we will talk about these newcomers who want to enter this industry.
1. Is it risky to breed crayfish?
The answer is, of course, yes. It can be said that there is no industry without risks. Doing anything that makes a difference requires twice as much blood to cope with risks.
Ordinary company employees are still at risk of being laid off, not to mention the controversial crayfish farming industry this year. However, the crayfish market is undergoing a major reshuffle. After this year, many farmers will quit this industry, and the future crayfish culture will inevitably change its development direction. The meager profit can't support the popularity of this industry at all, so I believe that most old shrimp farmers still hold a wait-and-see attitude towards next year's breeding.
The best way for newcomers who really want to participate in this industry is to learn technology and learn from old shrimp farmers. Not only have rich experience in breeding, but also the old shrimp farmers have been infiltrated in this industry for many years, and their sensitivity to the market is unmatched by newcomers. It is recommended that newcomers consult more humbly.
Second, what should I pay attention to when breeding crayfish?
For newcomers, getting started is very simple, as long as there is a large area of water, lying on the ground or rice fields and shrimp seedlings. But the beginning is simple, but the breeding process is difficult. What's the difficulty?
1. Water quality management
The high-density culture of crayfish requires very high water bodies. Of course, if you just keep a dozen for fun, you can keep them as you want. Crayfish is tenacious, but it can live anyway. But if you want to make money by large-scale farming, you must remember that crayfish have very high requirements for water bodies. Crayfish is a benthic animal and likes the stable environment of water, otherwise it is easy to produce stress reaction. Water quality should be paid attention to from pH value, temperature, depth and dissolved oxygen. For details of these aspects, please refer to our previous articles. We're only talking about the general idea today.
2. Water grass management
In fact, aquatic plants are one of the main reasons affecting water quality, which are directly related to acid, alkali and dissolved oxygen. At the same time, aquatic plants can also be one of the affairs of crayfish. Because aquatic plants are so important, we list this one. The most suitable aquatic plant for crayfish culture is Elodea. The management of aquatic plants has also been carefully written in previous articles, so I won't say much here.
3. Disease prevention and control
Crayfish are prone to many diseases, such as shell rot, enteritis, black gill disease, soft shell disease, fiber disease, white spot syndrome and so on. The most famous "May Plague" is the outbreak of several diseases together, which makes people unable to find a clue, resulting in a large number of crayfish deaths due to untimely spraying of drugs, so the "May Plague" is also called "May Curse". The prevention and treatment methods and forms of these diseases are different. But once the disease occurs, it is likely to cause great losses. This is also an extremely laborious part for farmers. Experienced shrimp farmers can see the clue at the early stage of the disease and treat it immediately. Inexperienced farmers may not find any problems until crayfish are killed or injured less than half.
4. Feed and feed
When to feed and how to control the feeding amount? How to give medicine to crayfish when it is sick? Has the feed of crayfish never changed? Of course not. There will be different feeding requirements at different time periods, which all depends on the specific situation.
5. Selection, release and fishing of shrimp fry
The choice of shrimp seedlings is also a big problem. How big it is, what kind of shrimp seedlings are healthy, when to release them, and what kind of density to release them are all places that need attention. When the crayfish are cooked, it is best to pick up the shrimps and sell them, depending on the market sensitivity. New farmers are most likely to stumble in these places.
It can be said that crayfish are easy to raise and difficult to raise. The good thing is, as long as you have the basic conditions, you can start. As long as you are careful, you can raise it well. However, if you know all these things mentioned in the article, it is difficult to cultivate a truly experienced farmer. If you want to enter the aquaculture industry, the best way is to find an experienced old shrimp farmer to take with you, learn experience and technology, and finally you can raise good shrimp.
