CATDOLL : CATDOLL: How fast does crucian carp grow? How long does it take to reach 1 catties?

1. Crucian carp growth rate, how long does it take to reach 1 catties

Generally, crucian carp can grow about half a pound in a year. Crucian carp grows faster in waters with sufficient sunlight and abundant food; it grows slower in waters with low water temperature or lack of food. If the breeding density is too high, the growth rate will be even slower. Wild crucian carp grows relatively slowly. May and June of each year are the spawning period of wild crucian carp. It can grow to about 200-300 grams in a year and a half.

1. Crucian carp growth rate

1. The growth rate of crucian carp has a lot to do with the environment. In waters with sufficient light and abundant food, crucian carp generally grow very fast and can grow about half a pound a year. If the water temperature is too low or food is scarce, coupled with too high a breeding density, it will lead to slow growth.

2. Wild crucian carp grows slowly. May and June of each year are the spawning period of crucian carp. After hatching, the small crucian carp can grow to 20-30 grams in winter, 100-150 grams in the next summer, and more than 200 grams in the next winter. Generally speaking, the weight of wild crucian carp after two winters is about 200-300 grams.

2. How long does it take for a crucian carp to grow to 1 catties?

1. Engineered crucian carp, also known as Xiangyun crucian carp, is a triploid new fish species bred by bioengineering technology combining cell engineering and sexual hybridization. Compared with ordinary crucian carp, engineered crucian carp has the advantages of dysgenesis of gonads, strong disease resistance, tolerance to hypoxia and low temperature, wide diet, easy to catch, etc., especially fast growth rate, which is 3 times faster than ordinary crucian carp. Under artificial breeding, it only takes about half a year for the fry to grow to one kilogram.

2. Native crucian carp is a common type of crucian carp with a relatively long growth cycle. This type of crucian carp only grows a few taels a year and it takes several years to grow to one kilogram.

3. If silver crucian carp is fed artificially with feed, it can grow to about one kilogram in less than a year. The body shape and color of silver crucian carp are very similar to those of ordinary crucian carp, but its body is significantly taller and wider than ordinary crucian carp. Its body length is 1.9-2.4 times its height, and its body color is darker. It grows faster than native crucian carp, and its individual size is also larger, with the largest individual reaching about 3 kilograms.

2. How big can crucian carp grow in a year? Attached with breeding methods

The growth rate of wild crucian carp is generally slow. If it is hatched in May or June, it can generally grow to 100-150 grams in the summer of the second year. Compared with wild crucian carp, artificially cultivated crucian carp generally grows faster. It can reach 200 grams after half a year of cultivation. After one year of cultivation, the weight of crucian carp can reach 1 jin. The growth rate of crucian carp also depends on the suitability of the surrounding environment. When various environmental conditions are relatively suitable and there is sufficient food around, the growth rate of crucian carp is naturally faster.

1. How big can crucian carp grow in a year?

1. In terms of body size, crucian carp is very small and its growth rate is not very fast. Specifically, the growth rate of crucian carp living in different environmental conditions will also be different. The growth rate of wild crucian carp is relatively slow. If it is hatched from May to June, it can generally grow to 100-150 grams in the summer of the second year.

2. Compared with wild crucian carp, artificially farmed crucian carp grows faster. It can reach 200 grams after about half a year of farming, and its weight can reach 1 jin after one year of farming.

3. How big crucian carp can grow is related to the suitability of the surrounding environment. When various environmental conditions are suitable and there is sufficient food around, crucian carp will grow faster and grow larger.

2. Crucian carp breeding method

1. Breeding preparation

(1) Be sure to choose a suitable aquaculture pond, such as building a pond in a location that is sheltered from the wind, facing the sun, and with convenient drainage. Drain the pond water, expose it to the sun for a few days, and then disinfect it with quicklime before releasing the water.

(2) Choose the species to be farmed. After years of artificial breeding and selection, many new species of crucian carp have been produced. You can choose the high-back crucian carp, which grows 2-3 times faster than other species.

(3) Choose high-quality feed for breeding, the protein content must be above 30%.

2. Planting seedlings

(1) When stocking the seedlings, the water temperature must be kept above 10°C. Too low a water temperature will affect the survival rate of the seedlings. In order to facilitate watering for breeding and sale, the seedlings must be stocked all at once. They cannot be stocked in several batches, which would make breeding inconvenient.

(2) The seedlings must be disinfected before stocking to reduce the chance of common diseases. Generally, about 2,000 seedlings are stocked per acre. Too dense a population will be detrimental to their growth. They can also be raised together with other fish for a more effective breeding effect.

3. Water quality management

(1) Crucian carp is rich in calcium and phosphorus. These two substances are 2-3 times that of other fish. Therefore, when breeding crucian carp, the calcium and phosphorus content of the water must be guaranteed to meet its growth needs. Lime solution and calcium phosphate can be applied once every half a month.

(2) Other trace elements are also indispensable, so organic fertilizers must be applied according to changes in water quality. If necessary, duckweed or chlorella can be cultivated in the pond.

(3) Pay attention to changes in water quality when the temperature is high. If the water quality is too poor, change the water in time.

4. Feeding management

(1) Crucian carp is an omnivorous fish that feeds on plants. The feed must be in line with the preferences of crucian carp. It should be fed in small amounts and multiple times, 6 to 8 times a day, and not too much each time.

(2) In spring, the temperature is lower and crucian carp's food intake decreases. At this time, the number of feedings can be reduced. In summer, the temperature is higher and crucian carp's food intake increases. This is a period of rapid growth, so the amount and frequency of feeding must be increased.

5. Disease prevention and control

(1) Diseases should be prevented. Diseases of crucian carp include saprolegniasis, hepatobiliary syndrome, and red gill disease. If these diseases are not treated in time, they will lead to the death of crucian carp.

(2) Sprinkle quicklime regularly for disinfection and sterilization to reduce the possibility of disease.

3. Crucian carp living environment and characteristics

Crucian carp is a bottom-dwelling fish that grows in a deep and warm environment. Therefore, when breeding, it is necessary to plant aquatic plants in the pond and control the water temperature at around 20 degrees. At the same time, crucian carp likes clean water, so in daily management, it is necessary to replace the water for crucian carp in time and provide it with high-protein feed.

What are the characteristics of crucian carp? 1. Benthic fish

Crucian carp is a bottom-dwelling fish and is suitable for growing in an environment with a certain depth and overgrown weeds. Therefore, when breeding crucian carp, you can choose a pond with open terrain, good ventilation and sunshine as the breeding place, clean up the debris at the bottom of the pond, plant aquatic plants, and provide a good growth environment for crucian carp.

2. Likes warmth and is afraid of light

Crucian carp likes warmth but is afraid of light, and is suitable for growing in a warm and dark environment. Therefore, during the breeding process, the water temperature needs to be controlled at around 20 degrees to maintain the growth of the crucian carp. At the same time, you can also cover the water surface with a shade net to prevent strong light from sunburning the crucian carp and affecting its growth.

3. Clear water quality

Crucian carp has high requirements for water quality during its growth and prefers to grow in a clear water environment. In daily management, it is necessary to change the water for crucian carp every week, and the amount of water change needs to be controlled at one-third to prevent the crucian carp from being unable to adapt. If conditions permit, you can use flowing water culture.

4. Omnivorous fish

Crucian carp is an omnivorous fish. During its growth process, it can eat grass stems and young shoots in the water, as well as earthworms, fish, shrimp and other foods. Therefore, when breeding crucian carp, you can provide it with grain feed with high starch content and animal feed with high protein content.
