How many centimeters are grass carp fry 1 catty 40 in 3 months

Grass carp is a common large freshwater fish, the general individual is about 5 10 kg, the largest individual can reach more than 40 kg, the maximum body length can reach more than 1 meter, but more than 20 kg of grass carp is extremely rare, in fact, the grass carp individual is within 20 kg, of which 5 10 kg of grass carp is the most common.

2. Growth rate.

The growth rate of grass carp is very fast, under natural conditions, 1-year-old fish can reach kilograms, 2-year-old fish can reach kilograms, 3-year-old fish can reach 5 kilograms, 4-year-old fish can reach 7 kilograms, and 5-year-old fish can reach more than kilograms, especially the weight of 2 3-year-old fish increases the fastest, so artificial grass carp are generally only raised for 2 3 years.

3. Average life expectancy.

The life span of grass carp is long, it can reach more than 40 years under natural conditions, but it is generally within 10 years, affected by natural conditions and artificial fishery and other factors, most grass carp can not complete the whole life process and die, under normal circumstances, grass carp can live to 7 or 8 years is relatively long.

Fourth, living habits.

1. Herbivorous: Grass carp is a herbivorous fish, mainly algae and aquatic plants.

It feeds on rhizomes, shoots, fruits, etc., and also eats zooplankton, aquatic insects, and earthworms.

Dragonflies and other meat food.

2. Social life: grass carp is a social fish, which likes to live in the middle and lower layers of the water area and the many aquatic grasses near the shore.

area, sexually active, fast swimmer, often in groups in search of food in waters rich in aquatic weeds.

3. Ectothermic: Grass carp is an ectothermic fish, which is most suitable for survival temperature 20 32 and feeding critical temperature.

5 35 , when the water temperature is higher than 5 and lower than 35, you can maintain a certain desire to eat.

4. Migratory: grass carp is a migratory fish, usually fattened in large waters such as lakes and reservoirs, and will swim to the middle and lower reaches of the river in late autumn and early winter to winter, and then trace the river to the middle and upper reaches to spawn in the spring of the following year.

8 cm grass carp fry can grow to about 12-15 cm in 3 months.

Raising this kind of fish is generally raised from the fry, select the good quality fry, put it into the breeding pond in the right season, the water in the pond must be clean and pollution-free, and also pay attention to the depth of the water, usually between meters.

Usually you can feed pellets, which have a higher protein content and help them grow, but you can't overfeed them, especially in the hot season.

2-3 cm grass carp fry can be about 15-25 cm a year.

Two or three centimeter grass carp fry grow rapidly in the early stage. If it grows normally, 2-3 cm grass carp fry can grow to about 15-21cm a year. 2-3cm grass carp fry are in the juvenile stage, the growth rate is relatively fast, in terms of length, the overall length can grow to about 25cm in one year.

Grass carp is a herbivorous fish that usually feeds on aquatic plants or algae. But they also eat insects because insects are rich in protein and other nutrients, which can make grass carp grow faster and bigger. If there are fewer insects in the water, the growth of grass carp fry will be slower, and if there are more insects in the water, it may grow to about 18-25cm a year.

How do grass carp grow fast?

1. Provide sufficient space

Generally, grass carp breeding should pay special attention to the problem of density, which is to raise a large area in the fish pond, and the number must not be too much and not too dense. It is necessary to provide them with plenty of space to move around, so that grass carp can grow quickly.

2. Provide adequate food

Grass carp need to be fed every day, and young grass should be selected to feed grass carp and add some insects from time to time to promote their rapid growth, so that grass is conducive to their digestion and absorption.

3. Ensure that the environment is suitable

There are many environmental factors that can affect the growth rate of grass carp, such as water temperature, this factor will greatly affect the appetite of grass carp, which can affect the growth rate of grass carp, and can keep the water temperature at about 20°C. Keeping the water clean can promote the rapid growth of grass carp, and the water quality will also affect the growth rate of grass carp. There is also the oxygen content in the water, which can be properly oxygenated if necessary.

4. Regular disinfection

Before putting grass carp into the pond, it must be properly disinfected, for example, with quicklime. In the future breeding process, we must do a good job of disinfection, which can avoid the breeding of harmful bacteria, prevent grass carp from getting sick, and make them grow faster.

It takes about 2 to 3 months, and the grass carp fry can grow to half a catty in the longest winter.

For this problem, it also depends on the place where you are located, what are the conditions of the fish pond, because the good or bad conditions of the fish pond will directly affect the growth rate of the fish, and the average annual temperature of your location will have a greater impact on the growth of the fish, the growth temperature of the grass carp is between 20-32 degrees, of which 25-32 degrees is the optimal temperature, so the general north is the shorter the growing season of the fish in a year, and it will be much longer in the south.

We take the Yangtze River basin.

For the grass carp farmed in the area, generally from the fish eggs just hatched out of the seedlings to open the culture, after a winter if the breeding is good, the bait in the pond is sufficient, can grow to 2-3 taels, the big has 4 taels, but this kind of large-size fish is not much.

Growth cycle of grass carp:

The fastest growth period of grass carp body length was 1-2 years old, and the most rapid weight increase was 2-3 years old. When 4-year-old fish reach sexual maturity.

After that, growth slowed down significantly.

1. The body length of winter-year-old fish is about 340 mm, and the weight is about 750 grams;

2. Winter-old fish are about 600 mm long and weigh kilograms;

3. The body length of winter-aged fish is about 680 mm and the weight is about 5 kg;

4. The body length of winter-aged fish is about 740 mm and the weight is about 7 kg;

5. The body of winter-year-old fish can reach about 780 mm and weigh about kilograms;

The largest individual can reach about 40 kg.

Habits of grass carp:

Grass carp generally prefer to inhabit the middle and lower layers of rivers, lakes and other waters, as well as near-shore aquatic grass areas. It has a migratory habit of rivers and lakes, and sexually mature individuals spawn in river waters, and after spawning, broodstock and juveniles enter tributaries and rivers and lakes, usually in shallow grasslands and floodplains that are flooded.

area and the water bodies attached to the main and tributaries feed and fatten. In winter, it overwinters in the deep waters of the main stream or lake. It feeds on zooplankton at the fry stage, and eats insects and earthworms at the juvenile stage.

Algae and duckweed.

When the body length is about 10 cm or more, it completely ingests aquatic life.

Higher plants, especially grasses. Grass carp has a lively temperament, swims quickly, often forages in groups, and is a gluttonous fish, which is a typical herbivorous fish. The types of plants that grass carp feed on vary according to the food base of their living environment.

Grass carp reproduces similarly to other domestic fish species and cannot spawn in still water under natural conditions. The spawning site is generally selected at the confluence of the main stream of the river and the meander.

The deep trough water on one side and the section of the river that suddenly tightens on both sides are suitable spawning grounds. The reproductive season is similar to that of silver carp, and it is more common than herring.

and bighead carp a little earlier.

A pound of grass carp fry is about 5 yuan a pound. It's cheaper to shop online**. Here's a look at what you need to know.

Selecting fry is an important part. When selecting the fry, we need to look at the activity of the fry, and also carefully observe the state of the fish in the feeding. Active fry will grow healthier, be sure to carefully observe whether there are wounds under the scales, and never buy injured fish.

However, it is best to breed grass carp with carp when we breed grass carp in captivity, so as to improve the efficiency of farming. However, it is necessary to remind everyone that the number of other mixed fish should not be too much, otherwise other fish will compete with grass carp for food, affecting the development of grass carp.

Scientific management methods of grass carp fry:

1. The feeding and activities of the fry can be observed everywhere around the pond, and the whole situation of the pond can be accurately grasped in a timely manner.

2. Within 1 week of seedling, we should try our best to create an environment suitable for splash life. If the water color has receded and there is little plankton, more soy milk or manure should be thrown in time.

3. Artificial soybean milk and other feeds should be fed in an appropriate amount, generally once a day in the morning and in the afternoon, and gradually increase the amount of bait as the fry grow. In addition to this, the cultivation of fertilizer water to propagate a large amount of natural bait. After about 10 days of cultivation, some have begun to change their eating habits, at this time, it is necessary to feed some Pingsha and duckweed in moderation to attract food, and pay attention to the clean and fresh green fodder, and strictly prevent diseases from entering the mouth.

At the same time, the dissolved oxygen situation of the pond is closely observed. When the hypoxic floating head in the pool is serious, new water should be filled in time. In case of sultry weather and sudden thundershowers, the upper and lower layers of water in the pond are convection, a large amount of residue gushes up to the surface of the water from the bottom of the pond, and the fry reduce or basically stop eating, this situation is easy to induce flooding, and in this case, immediately inject new water or turn on the aerator.

4. After about 1 month of cultivation, the feeding habits have already been transformed, and the specifications are all in 3 4 cm, at this time it is the summer flower fry, except for some **, it must be managed in the pond, leaving only about 10,000 summer flowers per mu to continue to cultivate until winter and spring. In the first 2 days of pond separation, it is necessary to carry out the adaptability exercise of pulling the net, and the operation should be light and agile, so as to reduce the scratching caused by man.

5. In terms of disease prevention, it is generally carried out according to the conventional disinfection method. After autumn, bait is cast once in the morning and once in the afternoon. After several months of careful breeding to winter, the fry basically reach 10 20 cm, into the winter, the temperature is very low, such as the temporary release, the fingerlings and in the deeper pond winter, waiting for the spring.

Hello dear, the information I found for you shows that the grass carp is 30 cm long and weighs about 4 catties. Grass carp grows faster.

1. The body length of the fish is about 340 mm, and the weight is about 750 grams; 2-year-old fish with a body length of about 600 mm and a weight of kilograms; The body length of the 3-year-old fish is about 680 mm and the weight is about 5 kg; At the age of 4, the body of the fish is about 740 mm long and curved, and the weight is about 7 kg; The body of the 5-year-old fish can reach about 780 mm, and the sock liquid weighs about kilograms; The maximum number of buried finches can reach about 40 kg.

Summary. 2 cm grass carp fry can grow to 3 cm in a month. 1. Growth rate:

Grass carp belongs to freshwater fish, sexual maturity age is 3-4 winter age, weight more than 5 kg, fast growth rate, fish fry of the year, summer flowers or autumn flowers of the year, under general breeding conditions, summer flowers or autumn flowers of the current year, grass carp fingerlings of about 2-3 cm, after a winter and spring feeding, can reach more than 5 cm; Under the conditions of winter and spring breeding, grass carp fingerlings of about 2 cm can reach more than 6 cm after two winter and spring feeding. Under good feeding management conditions, the growth rate of grass carp is relatively fast. 2. Nutritional needs:

Due to the wide range of feeding habits of grass carp, grass carp are very interested in all kinds of artificial feed, and have a great appetite, so it is not difficult to raise grass carp.

Ten months.

Grass carp fry grow relatively fast, from 3cm to 2 catties it takes ten months, this fish is one of the four major fish in our country, is a herbivorous fish, usually feeds on aquatic plants and algae, but can also eat insects.

It generally lives in the middle and lower layers of the water body, likes to inhabit in the waters rich in aquatic grasses, has a relatively lively personality, and swims quickly, usually foraging in groups, and has a certain economic value.

Adult grass carp mainly eat pellet feed because the feed contains 28 to 32 protein to ensure that grass carp feed and forage feed are adequately nutritious.

They should be fed once a day, in the morning and in the evening, in a amount that allows them to eat in 2 hours.

The daily intake should be controlled at 3%, and in order to control grass carp diseases, the intake rate of protein-containing grains should be reduced to about 2% to improve the feed intake rate.

During a period of cold weather, the continuous feeding of 32% protein-containing cereal feed should be stopped, and some raw materials should be fed every week or so, so that the grass carp fed is more economically valuable.
