The ancients said: "There is a succession of hearing the Tao, and there is a specialization in the art industry", and we rural people also have an old saying, called "what mountain to go up, what song to sing". Since Muhai himself is in the field of aquatic products, he will combine what he knows here and talk about the special breeding of aquatic products.
With the loneliness of bulk freshwater fish in the aquatic market, special aquatic products have sprung up, and there is a great momentum of catching up. From the price point of view, the aquaculture species that can be called "famous and excellent" have always been high, surpassing the four major fish. The following is a one-by-one introduction (the length may be a little long, first a multi-image warning):
Yellowtail
The price of yellow jaw fish is generally about 12 yuan / catty, and there is large-scale farming in Huzhou, Zhejiang, and the production in Hubei and other places is also very high. Due to its strong disease resistance, superior growth performance and strong ability to tolerate low oxygen, yellow jaw fish can adapt to high-density farming, and the yield per mu is very high.
Because male yellowtails grow faster than females and have larger individuals, in order to further increase production and meet market demand, the all-male yellow mulberry fish species also came into being. The yield of 5,000 jin per mu is generally not much pressure, and it is also possible to produce 10,000 jin per mu if the aquaculture water quality is good and the management ability is strong.
With the continuous improvement of production, the market price of yellow jaw fish has gradually declined in the past two years, but in any case, 10 yuan / catty is still a relatively solid bottom line for the present. When the price of four large fish is struggling below 10 yuan, what reason do farmers have not to choose the more efficient all-male yellow jaw fish?
Ayu, I believe many people have heard of this name for the first time. However, as the "king of freshwater fish", ayu not only has a delicious and unique flavor, but also has a deep cultural heritage.
For the grand situation of the ayu resources, the "Yandang Mountain Chronicle" has such a record: "Wherever the water flows, there is also yongnan creek in the west, from the maple forest, the stall creek, the lower pond, and the ancient temple pond." "During the season when the ayu swims, there will be a school of ayu in the rivers and streams. However, the lifespan of ayu is only one year, and the broodstock will die after spawning, which is similar to the salmon in the northeast.
California perch farming in the south is very popular, and even formed a complete industrial chain: from special compound feed to special animal protection products, from seed to growing to processing, in short, this fish has completely supported a market.
At present, the California perch market has differences in selling prices due to the size of the specifications, and the price of a pound or so of commercial fish is generally at the price of 15 yuan. Due to the huge production and climatic factors, prices fluctuate frequently and are for reference only.
Shanghai Aquarium: Rouge
Rouge fish is a valuable freshwater fish native to China, which is known as "smooth sailing" in the aquaculture industry, and originates in the Yangtze River and Minjiang River water systems. Rouge is a second-class aquatic protected animal in China, so it is necessary to obtain a special economic animal breeding and domestication license and a business and sales license before breeding. Otherwise, it will touch the bottom line of the law and belong to illegal farming. In addition, wild cochineal is prohibited from being sold and eaten, which please note.
Under natural conditions, wild cochineals have a high dorsal fin in the juvenile stage and gradually degenerate in adulthood, which may be a survival strategy to improve their own survival rate. In terms of growth, the body length of the cochineal fish can reach 20 cm a year, the weight of 2-year-old fish can reach 2 kg, and the mature individual can reach 20 kg. The cochineal can reach a maximum length of more than 1 meter, and the maximum weight of the cochineal fish that has been reported so far is 50 kg.
There are very few military fish farming in the northern region of China, and the main website areas are concentrated in Hunan, Sichuan, Yunnan, Guizhou and other places, which are special fish in mountain streams.
The scientific name of the military fish is light barbed catfish, the scientific name of the blue wave fish is Chinese barbed catfish, and the scientific name of the green bamboo fish is barbed catfish, these three kinds of fish have similar water quality requirements, living habits are also very similar, and the classification status is all fish of the genus barbed catfish, which have a certain blood relationship. Since these several types of barbed catfish have a certain farm value, another picture is attached for the reader to distinguish.
Guangxi osmanthus fish
In the Qing Dynasty, Zhang Zhihe had a poem: "The egret flies in front of the Xisai Mountain, and the peach blossom flows with mandarin fish fat". Mandarin fish as a traditional precious fish species, the market price remains high, Songhua River mandarin fish is one of the four major freshwater famous fish in China, and the related verses and allusions are countless.
At present, the artificially farmed mandarin fish species include warped mandarin, big-eyed mandarin, spotted mandarin, etc., of which the warp-billed mandarin fish grows the fastest and breeds the most, followed by the big-eyed mandarin, and although the spotted mandarin grows slower, the market price is higher. Therefore, the selection of varieties can be determined according to the market environment, personal positioning and production plan.
Mandarin fish is fresh and expensive for a reason. One of the most important points is that mandarin fish only eat live bait for life, especially long striped fish such as wheat ears, white stripes and grass carp, and the difficulty of domesticating food also raises the technical threshold of mandarin fish farming.
In order to reduce the production cost of mandarin fish farming, domestication technology and feed research and development are the key, and the breeding mode can also play a good auxiliary role in increasing production. We may wish to wait and see.
The scientific name of the duckbill is spoon-sturgeon, which has been specially introduced in Muhai's personal homepage to introduce life habits and breeding characteristics, and will not be repeated here.
The meat of the duckbill is tender and high in nutritional value, the snout is rich in collagen; the fish roe can be made into high-quality caviar, which is of great economic value; even the fish skin can be made into the best leather. After a year of captive rearing, the duckbill can grow to about 0.7-1 kg, weighing 2-3 kg in two years, reaching the market specifications. The highest weight recorded for duckbills is 65 kg, which is comparable to the weight of adult males.
Duckbill culture fry is the key, the best way is pond culture and reservoir stocking, can replace the cultivation of silver carp, of course, the economic benefits are certainly much higher than the silver carp.
Bamboo shoot shell fish scientific name shatang snakehead, is a new species introduced from Thailand, in the early stage of promotion of the market price of more than 100 yuan / catty, a fish is a hundred yuan.
It should be noted that some markets have requirements for the specifications of bamboo shoot shell fish, 1-2 pounds of the most popular, larger sizes are easy to sell, or even can not be sold, so it is very important to control the breeding specifications, you can consider batches of fish, round fishing and rotation, should improve the overall economic benefits.
