Winter breeding famous fish has many advantages

After the “winter season” began, the weather became colder and the water temperature dropped. Many farmers mistakenly believe that the famous fishes are not long and they lack the means of protection. This is a misunderstanding. Winter fish has many advantages: First, the cold water temperature is low, the decomposition of organic fertilizers in ponds is slow, the pond water is fresh, and the oxygen is sufficient, which is beneficial to the famous fishes. The second is due to the bacteria in the cold ponds. The insects are not easy to breed and grow. The famous fishes have fewer diseases and the survival rate is high. Thirdly, some fish ponds are used for dry pond disinfection. There are many kinds of wild fish and shrimps that are famous for many kinds of famous fishes, and there are plenty of fish feeds. This is to solve the carnivorous problem. The difficulty of fresh feed for fish provides favorable conditions for cost reduction and efficiency improvement. So what are the best fish cultures in winter?

Now choose the best varieties introduced as follows: Carp Carp also called Osmanthus fish, the meat is delicious and smooth, and no fine bones, high body and side flat, back bulge, rich meat. Carp is a high-temperature fish. It can survive below 0°C or above 33°C. However, the optimum water temperature is between 18-30°C. It is one of the most suitable fishes for winter raising, and it is also the best for anti-season farming. One of the varieties.

Its cultivation method: First, purchase fry stock of 7-10 cm size, about 1500 stocks per acre, if stocking coarse fish species, then put 700-800 mu, the water quality should be fresh, and the water depth should be kept at about 1.5 meters. Feeding 3-5 kg ​​of feed fish per day, and the length of the feed fish is about 1/3 of the length of the carp seedlings. As the squid grows, feed fishes continue to increase, making it 80% fuller.

The second is to stockpile the pond. As the carp specializes in catching live fish as baits, individual sizes in stocking in Tong Tong vary greatly, and they tend to eat on their own. Therefore, it is necessary to classify stocking ponds for stocking, raise them together within 250 g, and stock up to 300 kg per acre. Around, scientific feeding, round catching, catching big stay, and even listing, improve efficiency.

Carp Carp Carp Carp Carp, also known as Bigmouth Bass, is a freshwater river fish native to North America. This fish has fast growth, wide adaptability, fewer diseases, short breeding cycle, good meat quality, and strong cold resistance. It can survive in the temperature range of 2-34°C, and the growth water temperature is 15-25°C. It is an excellent breed for winter culture.

However, for many years, this kind of fish has adopted the method of spring harvesting. The market is concentrated and the seasonal price difference is very large. In the second and third quarters of the year, the price of goods is high, and the wholesale price per kilogram is about 10 yuan. In winter and spring, it rises to 25-30 yuan. Therefore, it is imperative that all localities use their appropriate temperature and wide features to vigorously promote anti-season farming, rearing 5–7 cm fry 2000–2500 acre per acre, and if larger 50–100 g fish species, acre 1000–1500 acre. And with 30-50 tail squid to purify the water quality, the feed is mainly fresh live wild fish, sea ice chilled fish, and hard chopped into the corners of the fish ponds, to develop its good habit of positioning food, every day at 10:00 At 5 pm each time, the feed volume is controlled at about 7% to 10% of the total fish production, and it is appropriate to eat within two hours after feeding. In feeding and management, stick to the morning and evening patrols. Special attention should be paid to changes in water quality and the fish’s food intake, and new water should be regularly added to promote its appetite, prevent its floating heads from lacking oxygen, catch fish regularly, catch large fish, and keep a reasonable amount of fish in the pond.

The large-spotted catfish, also known as gully, is native to North America. It is a good breed with fast growth, large individual size, wide appetite, high yield, and strong disease resistance. It breeds after two or three years of breeding. Up to 5-6 kilograms, its meat is delicate, delicious, the fish adaptability to the water temperature is also very large, in the 0-38 °C, can survive, the water temperature rose above 5 °C began to eat, is Guangdong throughout the year Aquaculture fish accounts for 40% of the freshwater fish supply in the U.S. market. It is particularly large and fleshy and has less bone spurs. It is an important raw material for the production of canned fish in the future. It is an important economy for China to strive for exports after China's accession to the WTO and should cause heights. Pay attention.

The ichnich is a kind of omnivorous fish. In the seedling stage, zooplankton species such as ribeyes, arborids, rotifers, etc. are dominant. Human and animal manure can be used for cultivation. In the stage of adult fish breeding, benthic organisms and small animals are used. Miscellaneous fish, algae, and aquatic plants are the main sources, but artificially formulated pellet feeds can also be fed. The source of feed is wide, and the cost of breeding is low. There can be 800-1000 tails of 15-20 cm species of fish per mu and 100-150 tails of carp fry. Feeding twice a day, at 9 a.m. and 5 p.m. once a day, the amount of feed per day is controlled between 3% and 4% of the total weight of the fish body, and the degree of eating is about 1 hour after feeding, and the cold wave is coming. In case of overcast or rainy weather, it is necessary to cast a small amount of water to prevent water pollution. Sooner or later, it is necessary to watch the pond and observe the floating head of the fish. Evening patrol ponds, mainly check the food throughout the day, there are no signs of residual baits and fish. Drainage and irrigation should be matched and new water should be added regularly to ensure that the pond water has a high dissolved oxygen content, promotes fish appetite, accelerates growth, and reduces fish disease.
