The body color of adult fish is slightly golden yellow.
1. Carassius auratus has high meat content and high nutritional value.
Golden crucian carp has the characteristics of thick body, tight meat quality, high meat content and few spines.
Golden crucian carp has a beautiful figure (slightly wider and thicker than Pengze crucian carp), moderate body length, neat pulp slices and crystal-clear and solid scales, which is suitable for long-distance transportation.
The body color of adult fish is slightly golden yellow.
1. Carassius auratus has high meat content and high nutritional value.
Golden crucian carp is fat and thick, with compact meat, high meat content, few spines, small organs, delicious fish and rich nutrition.
It has been proved by national authorities that the meat content of golden crucian carp is higher than that of Pengze crucian carp 1 1%, and it contains 23 kinds of amino acids.
2. Wide temperature range.
The temperature range of golden crucian carp is very wide, and it can survive normally at 0 ~ 38℃.
Its growth water temperature is 12-32' E, and its vigorous growth water temperature is 16 ~ 28℃.
3. Strong cold resistance.
The water level of the pool is kept above 1.5m, and all water bodies or waters that meet the standards can safely overwinter.
4. Good resistance.
Golden crucian carp has low requirements for water environment. The water used to raise carp and crucian carp can be used to raise golden crucian carp. The oxygen consumption rate is extremely low, as long as the oxygen in the pool water is kept at 3 mg/
When the pH value is above 7-9.4, it has no effect on its feeding, feed conversion rate and growth.
5. Strong disease resistance.
Carassius auratus has been cultured for more than two years, and there has never been an epidemic or sudden disease. In addition, parasitic diseases such as rotifer, third generation worm, giant salamander and anchovy in adult fish are less than those in other cultured fish.
6. Golden crucian carp has been eaten for a long time.
Because it takes a long time to eat, it is easy to take the bait, and it is an excellent species in the fishing industry.
When the water temperature rose above 6℃ in early spring, the species began to feed, and when the water temperature dropped to about 5℃ in late autumn, it still ate to varying degrees, which prolonged the feeding time.
7. Golden crucian carp is easy to breed.
Golden crucian carp is gentle in temperament and naturally has the habit of foraging in groups. It will eat on the stage, not domesticated, eat honestly, not fried, and reduce feed waste.
Key points of culture of golden crucian carp
1. Conditions of golden crucian carp culture pond.
Ponds can be large or small, 3 acres to dozens of acres, as long as the water level can be kept above 2 meters.
2. Golden crucian carp culture mode.
There are three kinds: the first is to cultivate large-scale fish species in summer flowers, the second is to cultivate commercial fish in summer flowers that year, and the third is to cultivate finished fish.
3. Feeding points of golden crucian carp culture.
The content of protein in the bait is not less than 36%-38% in the larval and larval stages, and not less than 34%-35% in the adult stage. It can be fed 2-3 times a day, each time for 1 ~ 1.5 hours.
The daily feeding amount is 5% ~ 8% of the total weight of juvenile and larval pond fish, and 3% ~ 4% of the total weight of threatened pond fish.
4. Pond management of golden crucian carp culture.
Patrol the pond every morning and evening 1 time.
Keep the pool water oily green and light green.
Start the aerator at the right time, every day in midsummer, at midnight in rainy days, and after heavy rain.
The optimum value of dissolved oxygen in the pool is kept above 3 mg/L throughout the year.
