In 20 19, the "diving price drop" of crayfish market was widely heard on the internet, but shrimp farmers complained 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 about the future development trend of crayfish culture, from cheap to fine, from individual concentration to year-round, to prove 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 we 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 to make a difference requires spending 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 are still holding 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 the experience of 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, it is very simple to get started, as long as there are large areas such as water, lying or rice fields and shrimp seedlings. But the beginning is simple, but the breeding process is difficult. What are the difficulties?
1. Water quality management
High-density culture of crayfish requires very high water bodies. Of course, if you just raise a dozen for fun, you can do whatever you want. Crayfish are very tenacious and can live anyway. But if you want to make money from large-scale farming, you must remember that crayfish have very high requirements for water bodies. Crawfish are benthic animals and like the stable environment of water bodies, otherwise it is prone to stress reactions. Water quality should be paid attention to from the aspects of pH value, temperature, depth, dissolved oxygen and so on. For the detailed contents of these aspects, please refer to our previous articles. We only talk about the general idea today.
2. Water grass management
In fact, aquatic plants are one of the major causes affecting water quality, and have a direct relationship with acid, alkali, dissolved oxygen and so on. At the same time, aquatic plants can also be used as one of the affairs of crayfish. Because aquatic plants are too important, we list this as a separate item. The most suitable aquatic plant for crayfish culture is Elodea sp. The management of aquatic plants has also been carefully written in the previous article, so I won't talk about it here.
3. Disease prevention and control
Crayfish are prone to many diseases, such as rotten shell disease, enteritis, black gill disease, soft shell disease, ciliary disease, white spot syndrome, etc. The most famous "May plague" is that several diseases break out together, which makes people unable to find a clue, leading to a large number of crayfish deaths due to untimely spraying of drugs, so "May plague" is also called "May curse". The prevention and treatment methods of these diseases are different, and the forms are different. But once the disease occurs, it is likely to cause a lot of losses. This is also an extremely laborious part for farmers. Experienced shrimp farmers can see the clues at the beginning of the disease and treat it immediately. Inexperienced farmers may not find anything wrong until crayfish have been killed or injured for less than half.
4. Feed and feeding
When to feed and how to control the amount of feed? How to administer crayfish if 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 depend on the specific situation.
5. Selection, release and fishing of shrimp seedlings
The choice of shrimp seedlings is also a big problem. How big to be, what kind of shrimp seedlings are healthy, when to release them, and what kind of density to release them, these are all places that need attention. When crayfish are ripe, it is best to pick up shrimps and sell them, which depends entirely on the market acumen. Newcomer 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 that as long as you have the basic conditions, you can start with it. As long as you are careful, you can raise it well. But it's difficult to raise a real experienced farmer only if you know all these things mentioned in the article. If you want to enter the aquaculture industry, the best way is to find an experienced old shrimp farmer to take it with you and learn experience and technology, and finally you can raise good shrimp.
