Indoor freshwater aquaculture white prawn, a net annual income of 350 thousand
The white prawns are usually kept outdoors in lakes or fish ponds, but here the white prawns are kept indoors in round ponds, so what about the white prawns here? Many farmers are very curious and interested in this kind of indoor white prawn. Today, let's take you to know about indoor freshwater white prawn farming.
Pick up some white prawns from the round pool. It is obvious that all these prawns are alive and kicking. They are very vigorous and healthy. Speaking of their South American white prawn, indoor farming chef that is full of confidence ah.
Why so confident? Once we asked the master, we understood clearly. Freshwater raised South American white shrimp, the overall color is more translucent than seawater raised shrimp, we picked up a shrimp, its lines, viscera are very clear to see. You can tell from the shrimp line that the shrimp is feeding, and of course, it looks like the shrimp is feeding well.
A series of investigations and groping, but unfortunately encountered a wall.
How can the white prawn, which originally lives in seawater, grow so well in fresh water? It's a secret! After understanding, we know that this is the master in the process of freshwater aquaculture, overcome many difficulties to achieve.
More than ten years ago, the master and his father raised four large fish together. By chance, the master heard from his friends that the market of white prawns was very good. After investigation, it was also found that the sales of white prawns was very good, and the price was rising every year. Shifu was very impressed by this investigation.
Light has the heart is useless, heart after the master immediately put into action. Since 2008, the master has been to Jiangsu, Zhejiang and other places to investigate. After investigation, the master found that farmers in coastal areas usually use seawater to raise white prawns, but this is very difficult to achieve in Hubei. In the course of Master Peng's apprenticeship, someone taught him a very useful method.
The old master tells the master that you can also raise white prawns with fresh water and sea salt. Adopted his method. In 2012, the master introduced the technology and method of freshwater aquaculture of South American white prawn to Hubei Province, and started aquaculture in the outer pond. But things didn't go so well. During the farming process, Peng found that the land was so salty and alkaline that the surrounding crops couldn't grow. This can worry bad. Pond mouth breeding is difficult to achieve, this can be how to breed again?
Misfortunes followed one another. Shifu insisted on exploring the true scriptures
At first, I thought the plan had been soaked in soup. However, with the teacher's continuous exploration, after two years of study and exploration, I successfully mastered the seawater desalination technology, and finally realized the freshwater aquaculture of South American white shrimp in Hubei Province. This method is both environmentally friendly and cost saving. What is the good method? The master gave us this introduction:
After their shrimp seedlings we transport back, and then we played down the pool, fake it growth environment, for it to achieve a "artificial sea water", and then through this way we additive part of fresh water a day, have replaced seawater out gradually, through this step, the shrimp seedlings gradually adapt to the growth of the fresh water environment.
In 2014, the chef began raising white prawns in fresh water in the fish pond. I thought that the technical difficulties had been overcome and the breeding was finally on the right track. However, in 2016, many areas in Xiaogan, Hubei Province were hit by floods. Most ponds were invaded by floods, and Shifu did not avoid them. In the face of setbacks, not only did not give up, but also have a new idea.
Master from then on, the outside pond farming into indoor factory farming, the change of farming mode, so that not only can not be affected by the weather, but also to increase production. At the beginning of last year, Master Peng's shrimp farm finally started to get on the right track.
In the process of breeding, the master invited a lot of technical personnel to carry out fine breeding of his South American white shrimp. Among them, the most important and always need to pay attention to the breeding process is feeding.
Nutrition collocation, learn to control materials.
Nutrient collocation requires us to feed different diets at different growth stages and stages of the shrimp. So as to ensure the shrimp's health and energy. According to the different growth stages of prawns, they need different nutrients, so they should be properly supplemented with bacteria and algae. After filling in, shrimp's constitution can be stronger.
How to carry out routine material control?
Accurate feed feeding is one of the most important work of prawn culture, and it is also a breeding technology that prawn personnel must master. The basic principle of feed is: accurate feed, rather less than more. It can choose to reduce the feed regularly or stop feeding 1 meal for a fixed period of time, which can well reduce the digestive load of the liver and intestines, promote the shrimp to eat algae, bacteria, bioflocs, etc., and supplement trace elements, indigenous flora and natural nutrients to promote gastrointestinal digestion and nutrient absorption and utilization. At the same time can also clear bottom water transfer, reduce pollution.
When feeding, farmers can stir and add lactic acid bacteria to feed, which can not only promote digestion, benefit intestinal health, improve the utilization rate of bait, reduce bait cost; It can also inhibit the breeding of harmful bacteria to a certain extent.
