The Price and Culture method of German Mirror Carp

German mirror carp is a variety introduced from the original West Germany, also known as Sanhua carp, three scales, iron back fish and so on. It has the characteristics of fast growth, miscellaneous eating habits, low temperature tolerance, strong adaptability, easy feeding, high starting rate and so on. Its growth rate is 20% to 30% faster than ordinary carp, and its meat quality is better than that of ordinary carp. It is very popular with consumers, and the market price is higher than that of ordinary carp. Let's take a look at the price and breeding methods of German mirror carp.

How much is the German mirror carp per jin?

The market price of German mirror carp is about 810 yuan per jin, and its price is generally slightly higher than that of ordinary carp. German mirror carp has been approved as an excellent aquaculture variety suitable for popularization by the Aquatic Variety examination and approval Committee of China, and its growth rate is very fast under reasonable stocking density and better feeding conditions. in Heilongjiang area (production period 120 days), the size of 2-year-old commercial fish can reach more than 1 kg, and its growth rate is much faster than that of other carps under the same conditions.

What are the varieties of German mirror carp?

1. German mirror carp: German mirror carp is an excellent variety of carp introduced from Germany in the 1980s. after more than 20 years of breeding, it has become one of the main breeds of common carp in China, with the characteristics of fast growth, miscellaneous eating habits, low temperature tolerance, easy feeding and so on.

2. Songpu mirror carp: Songpu mirror carp is a new variety with good shape, high and thick back, fast growth, strong cold resistance and high fecundity based on German mirror carp breeding line F4.

3. Loose-scale mirror carp: loose-scale mirror carp is a kind of carp without scales. The breeding line of German mirror carp, which is suitable for breeding in most parts of China, was selected by Heilongjiang Fisheries Research Institute after more than 20 years of systematic breeding from the former West Germany.

Culture methods of mirror carp in Germany

1. Pond culture: German mirror carp can be cultured in two ways: main culture and combined culture. 3000 million carps per mu are mainly cultured in ponds, and artificial fodder is fed. The crude protein content is required to reach 280.32%, and the amount of fish species in pond culture accounts for 50.10% of the total.

2, cage culture: German mirror carp cage culture can be floating or fixed, usually single culture, can also be matched with a certain proportion of silver carp, bighead carp, fine scale oblique jaw, but controlled at 3% 5% of the total stocking volume, with a stocking specification of 50 kg 150 grams per square meter and 30 fish species per square meter.

3. Rice field culture: German mirror carp rice field culture should select fields with sufficient water source, fresh and pollution-free water quality, convenient drainage, no water leakage and good water retention, with a stocking density of 3cm summer flowers or 100g fish species with a stocking density of 30mm / mu.

Culture methods of German mirror carp

1. Pond conditions: the pond area of German mirror carp culture is 5 mu and 20 mu, the depth is more than 2 meters, the water quality is fresh and pollution-free, equipped with aerator, the pond is thoroughly cleaned and disinfected 10 days before stocking, 200 kilograms of fermented manure per mu is applied, and the depth of water injection is 0.8 meters.

2. Fish restocking

① culture pond: from the middle of May to the beginning of June, the fingerling of black carp or summer flower with the size of 1.6cm or 3cm is released, the proportion of silver carp and bighead carp is 1x3ul, and the size of the fry out of the pond is 100g at harvest.

② adult fish pond: from the middle of April to the beginning of May, the fish species are released with about 100g spring fillet or 200kg 250g large spring fillet, the proportion of silver carp and bighead carp is 1g / 3vl, and the size is 750g at harvest.

3. Feed selection: German mirror carp culture uses artificial mixed pellet feed, the crude protein content of fish seed feed is required to reach 3035%, the crude protein content of adult fish feed is required to reach 280.30%, and the feed crushing fineness should be more than 40 mesh.

4. Feeding and domestication: German mirror carp adopt the method of domestication and feeding. A trestle with a length of 3 meters and 4 meters is built in each fish pond as a feeding platform. Spring fillets begin to be domesticated after entering the pond, and summer fry begin to be domesticated when they grow to 4 centimeters. Generally, it can be domesticated in 5 or 7 days.

5. Feed feeding: the daily feeding times of German mirror carp are generally 3 times from May to June, 4 times from July to August, 3 times in September, each feeding time is 20 minutes, and the appropriate feeding amount is 80% of the fish, that is, most of the fish swim away.

6. Water quality regulation: German mirror carp species are added with fresh water every 7-10 days, with a water depth of 20-30 cm each time until the water depth reaches 2-2.5 meters in July. On a sunny day in summer, the aerator is turned on for 1-2 hours, and raw lime water is sprinkled once every 15-20 days.

7. Prevention and treatment of fish disease: before the German mirror carp is planted in the pond, wash the fish with 35% salt water for 10 minutes for 20 minutes, sprinkle bleach, chlorine-rich and other fungicides in the whole pond every other month, and check the fish regularly at the same time. Fish diseases need to be treated in time.
