Blue fish (this article specifically refers to brown blue fish, that is, mud whale) is delicious meat, rich in nutrition, suitable for all ages, and is deeply loved by southern coastal residents. Due to the impact of diseases or market conditions on golden pomfret in recent years, the breeding efficiency is poor, especially last year, the price of golden pomfret fluctuated up and down the cost price for a long time, and farmers lost more and earned less, and the amount of blue fish culture this year quietly increased. At present, the blue fish has reached the late stage of breeding, and the overall breeding situation in various production areas this year is good.
Recently, the editors of aquatic hotspots investigated the specific conditions of the main blue-blooded fish producing areas such as Zhangzhou in Fujian, Yangjiang in Guangdong, Zhanjiang in Guangdong, and Beihai in Guangxi, as detailed below:
Zhangzhou Dongshan: The amount of breeding is large, and the veterans make money
Blue fish has a history of 20 or 30 years of farming in Dongshan and is also one of the main cultured species in the local area. Dongshan is mainly cage culture, every year around the Qingming Dynasty began to release seedlings aquaculture, latest to the second year of the lunar calendar in February full end of breeding; Dongshan also has a small number of polyculture of earthen ponds, which have basically ended, and in general, the blue fish cultured in tutangs is of higher quality and the price of fish is slightly higher. Experienced farmers can raise three batches of fish a year, while conservative farmers can breed two batches. For blue fish, the high temperature period is a severe test, so when breeding the first batch of fish, it is very difficult for farmers to fish out of the fish time, and it is necessary to get out of the fish early. Breeding winter fish is more of a gamble, and in the face of severe cold, there is a danger that the whole army will be destroyed. Usually the fish can be farmed to 9-12 fish / kg, and the first batch of fish on the market in the morning can reach more than 25 yuan / kg. With a large number of adult fish listed, the price of fish continues to fall, and the lowest price of 14 yuan / catty appears around the end of June, which is very close to the normal cost price. At present, the fish price is relatively stable, and the price of 3 two/ tail blue fish is 19.5 yuan / catty.
This year, the breeding situation of Dongshan blue fish is quite OK, the impact of high temperature and insect pests are all there, but there is not much problem; At the same time, because the price of seedlings this year is relatively cheap, the amount of breeding has increased, and the market is also general. Usually farmers with more than 3 years of breeding experience can basically make money, while new farmers may have to "pay tuition". Dongshan blue fish farming volume is large, start early, there is a special compound feed, feed capacity of more than 10,000 tons, many aquatic feed giants here to fight.
Yangjiang Yangxi: breeding has increased, and the market is good
Last year, the breeding of golden pomfret in Yangxi was not good, and the market was also poor, and this year' farmers replaced golden pomfret with blue fish. The polyculture of tutang culture is mainly polyculture, and the seedlings are put into seedlings after the Qingming Dynasty, and the breeding cycle is usually about 2 months. Although the specifications are small, but the market is good, 10-20 / kg of blue fish in the market can usually sell 18-20 yuan / kg, compared to golden pomfret, the income is not bad.
After October, the temperature begins to drop, but the water temperature in the sea is still suitable for the cultivation of blue fish. Cage culture of golden pomfret out of the fish, there are also some farmers with the empty cage seedlings to breed blue fish, the seedling size is about 50 / kg, usually farmed to the Spring Festival before and after the fish, at that time usually the fish price is higher, is expected to be about 2 two / tail.

Suburbs of Zhanjiang: The stock is not large, and the price of fish is stable and rising
Zhanjiang suburban aquaculture blue fish are mainly distributed in Potou, South Three Islands, soil pond polyculture is the mainstay, there are also a small number of cage culture, every year before and after the Qingming fry, the size of the fry is 100-200 fish / kg. In recent years, the high temperature of blue fish on the slope is serious, and the density of fry released this year has decreased, ranging from 50-200 seedlings per mu, which has also reduced the amount of aquaculture, but this year's breeding situation is good, and there are fewer dead fish. However, the situation in the South Three Islands this year is relatively poor, with more problems during the high temperature period and greater losses.
The daily market consumption of basket fish farmed in Zhanjiang is only a few hundred catties, and the fish production cycle is relatively long, and the current stock of basket fish is less than half. Due to the small amount of basket fish culture this year, fish prices are also stable and good. In late November, the price of 6-7 blue fish live and fresh pond head is 20 yuan / catty. It is estimated that the fish will continue until around the Spring Festival, when the size of the blue fish will reach 3-4 tails / catty, and the price of the pond head can reach 30 yuan / catty.
Zhanjiang Liusha Port: The early batch breeding effect is ideal, and the seedlings have continued to be released in recent days
In recent years, the situation of dead pomfret in Liusha Port has occurred every year, and the price of golden pomfret has continued to be sluggish since last year, resulting in more bluefish farming than golden pomfret this year. Early batch of seedlings before and after the Qingming, the size of the seedlings in 200-400 tails / kg, there are also some farmers plan to fish early, the size of the seedlings is larger, but the large size of the seedlings to adapt to the environment is poor, easy to stress, the survival rate is low. In August, the fish are concentrated, and the size is 7-8 fish per catty. Although the early batch of blue fish breeding process also lost a lot, but the fish price remained at 18-20 yuan / catty, the breeding efficiency is better than the golden pomfret.
After the early batch of blue fish is finished, the farmers continue to release the seedlings. After the middle of November, the cold air went south, the water temperature of the quicksand port dropped, and the winter fish entered the concentrated seedling release period, and the seedling specification was 100-200 fish/kg. Experienced farmers said that the release of seedlings in the high temperature period is easy to lead to a low survival rate of seedlings, so they usually wait until the temperature is cooled before releasing seedlings. Winter fish are expected to be farmed until the Spring Festival or after the Spring Festival before fishing.

Xu Wen: The long speed is slower, and it is still in the breeding period
Xu Wen breeds more blue fish mainly in Wailuo Port, this year's aquaculture has increased, and last year's golden pomfret farming efficiency is related to the poor efficiency, mainly small size fish row cage culture. This year's seedling release period is concentrated in May and October, which is slightly delayed compared with the past. The size of the blue fish fry released in May is very small, about 500 fish / kg, and the breeding situation in the high temperature period this year is poor, and the feeding is prone to dead fish; After the high temperature period, the water quality of the sea is poor, and the same does not dare to feed; It has only recently officially entered the growth period, so this year's blue fish growth rate is significantly slower. In October, there are also some blue fish farmers who release seedlings, and the size of the seedlings is larger than that in May, 50-100 fish/kg. Overall, the breeding situation of blue fish in Wailuo Port is general, the current size is about 1 two / tail, basically in the breeding period, the custom fish specifications are about 2 two / tail, it is estimated that the concentrated fish around the Spring Festival.
In addition, Xilian also has a small number of cages, high ponds, and earthen ponds for the cultivation of blue fish, which has considerable benefits.

Beihai Tieshan Port: Make full use of cages, fast maintenance and fast selling
Last year, the golden pomfret farmers in Tieshan Port suffered serious losses due to insect pests, and this year farmers were very cautious about breeding golden pomfret, the amount of aquaculture was reduced, and some cages were vacated for the cultivation of blue fish. Blue fish are usually released before and after the Qingming Dynasty, and the amount of seedlings is estimated to reach 30 million. Probably because of lack of experience, there are more diseases in the breeding process, and the overall survival rate is low, only about 50%. Fortunately, the blue fish breeding cycle is only more than two months, the fish price is very ideal, the purchase price of the early batch of fish is 30 yuan / kg, and the fish price in the later period is not less than 20 yuan / kg, so most farmers have money to earn.
However, blue fish is not the main breed of farmers in Tieshan Port. The high temperature period came, and the blue fish farming ended. Farmers sell all the bluefish and then divide the growing golden pomfret into empty cages to reduce the density of the golden pomfret.
Summary: Although the market is good, do not follow the trend
Although the blue fish is both afraid of cold and heat, it is also easy to eat, and it must pay attention to the control of the amount when feeding, but the breeding cycle is short, the capital is returned quickly, the risk is low, the disease is less than that of the golden pomfret, and the infrastructure facilities for the cultivation of golden pomfret can be fully utilized, complementary breeding, which to a certain extent reduces the market stock of golden pomfret and enriches people's tables.
However, the market capacity of each aquatic product species has an upper limit, basket fish is mainly based on the market, the market capacity is limited, fish prices are regulated by the market, once blindly farmed, the stock increases sharply, it is easy to follow in the footsteps of gold pomfret, resulting in a collapse in fish prices. In addition, many areas have only recently risen to cultivate blue fish, due to insufficient breeding experience, there are many examples of no return. Don't do it on a whim and follow the trend of breeding!
