CATDOLL : CATDOLL: How to raise carp at home

1. How to raise carp at home

1. If you don't have old water at home before buying fish, you need to use water that has been stagnant for seven days (that is, tap water that has been stored in other containers for more than seven days) to raise fish. Don't rush to put the fish into the tank after you bring them home. First, immerse the plastic bag containing the fish in the fish tank for ten to twenty minutes before opening it. Allow the water in the tank to flow back into the bag several times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality.

2. In addition to eating artificial baits, they prefer to eat bloodworms, earthworms, shrimps, egg yolks, etc. Make sure the bait is fresh and do not feed it if it is rotten or spoiled.

3. Feed once a day at a fixed time, feed until the fish is 80% full each time, and it is best if the fish can finish eating the food within five minutes.

4. Koi are not afraid of cold, but since you keep them indoors, I believe the temperature should not be very low. Generally, they will be fine as long as the water does not freeze. However, you should try to keep the water temperature constant. If the temperature fluctuates, they will definitely catch a cold.

5. If there is no filter, the fish feces should be sucked out on time every day, and then the same amount of trapped water (requires three days of trapping) should be added. In this way, only a small amount of water is changed, and the water can be kept clean and oxygenated. A large amount of water should be changed once a week (or when the water is muddy), that is, 3/1 water change is enough. Before changing the water, put the trapped water next to the fish tank a few hours in advance to ensure that the new water to be replaced is kept at the same temperature as the water in the fish tank, so that the fish will not be stimulated.

Just put it in the fish tank and feed it with food every day.

2. How to raise carp?

1. Summer flower cultivation

1. Pond preparation: Select an area of ​​1-2 mu, with a water depth of 0.8-1.2 meters, less silt, and an east-west fish pond. Clean and disinfect it according to conventional methods.

2. Fertilization (also known as putting fertilizer into the pond): 7-10 days before the fry are put into the pond, fermented manure can be applied, such as 150-300kg/mu (about 5 picks) of pig and cow manure, or 5-10kg/mu of inorganic fertilizer (chemical fertilizer, phosphate fertilizer, etc.), and quicklime disinfection (dosage 150kg/mu) can be carried out at the same time. A week later, the fry are put into the pond at the peak period of rotifers, and the fry have sufficient palatable bait and grow healthily.

3. Stocking: Before stocking the fry, use a fine mesh net to remove weeds. You can also stock 50 to 80 cheap silver carp fry to test the water. Once everything is safe, you can stock the fish, 100,000 to 250,000 per mu.

4. Put the fry into the pond with clear water: do not apply base fertilizer, but put the fry directly into the pond. This method is because there are less palatable bait rotifers in the water and there is not enough for the fry to eat, so the fry are weak and the survival rate is low.

5. Management:

(1) Timely feeding: After the fry are placed in the pond, they grow very fast in the first few days, and there is often a shortage of natural bait, so it is important to pay attention to feeding.

Soybeans and cooked egg yolks are often used to make a pulp and sprinkle it on the fish. Every day, 2-4kg of soybeans and 3-5 cooked egg yolks are ground into a pulp and sprinkled on the fish immediately, focusing on the water surface a few meters near the edge of the pond. Fresh filtered pig blood can also be sprinkled every three days. Soybean milk can be directly eaten by the seedlings, and it can also fertilize the water quality and enrich the natural bait. At present, there are also fish fry feeds circulating on the market, which are in the shape of microcapsules or powders. They can be fed from 6-8 minutes. They can not only supplement food, but also induce the fry to grab food, thereby promoting the development of the digestive tract, which is beneficial to improving the survival rate and strengthening the seedlings.

(2) Topdressing and water management: Topdressing should be done every three days to keep the rotifer level in the water at a high level. You can also draw some water from the fatter adult fish pond and add it to the fry pond every day to provide the fry with natural food and prevent the occurrence of bubble disease caused by adding too much water from the well. 1/3-1/2 of the water should be changed every week.

(3) Careful observation: During the fish fry cultivation process, more inspections should be carried out.

Observe their activities, feeding, growth, water quality changes, and whether there are enemies, diseases, etc. At the same time, the fry should be divided into ponds in a timely manner to prevent overcrowding and uneven sizes. If necessary, it is necessary to pull the net to exercise the fry to enhance their endurance.

Second-specification fish breeding: After summer flower breeding, the length and weight of the fry increase many times, and their adaptability is also greatly enhanced. The changes in their feeding habits have already shown the characteristics of the species, and they begin to like concentrated feed, so they should be smoothly transitioned to eating compound feed as soon as possible.

Feeding methods include:

1. Single culture method: select a disinfected pond of 2-4 mu with a water depth of 1-1.5 mu, put 3000-6000 summer flower fish fingerlings per mu, feed compound feed or a mixture of bean cake, silkworm pupae and fish meal, the protein content of the feed should be more than 35%, feed 8-12 times a day, and the feeding rate is 5-8%.

2. Mixed culture method: Mix carp summer flower with other fish species, with carp as the main or auxiliary.

If carp is the main fish, the feeding should be increased. If silver carp is the main fish, the water quality can be appropriately cultivated. If grass carp is the main fish, less carp should be released.

3. Feeding and management

(1) The earlier the fry start to eat, the better their growth will be. We should strive to smoothly transition to feeding with complete formula feed as soon as possible.

(2) Pay close attention to the early stages of the growth of the most edible fish (especially from the age of one inch to 25-30 days). Their length and weight increase rapidly and they require more feed. At this time, feeding should be increased. Some fishermen feed more than 10% of the fish during this period.

3. What should you feed carp raised in rice fields?

In order to ensure the quality of carp, it is best not to feed it anymore.

Pay attention to epidemic prevention, spread dry and pure wood ash in the rice fields every half a month, and do not spray herbicides and insecticides after releasing carp. No feed is needed, carp will eat algae in the rice fields, small earthworms, small maggots, small mayflies, rice pollen, etc.

Different regions can choose the stocking species according to different situations. In principle, all species suitable for pond farming can be farmed in rice fields, but rice fields are generally mainly carp, and some crucian carp, tilapia, etc. can also be raised. Carp can grow well in shallow water and are omnivorous. They can eat weed seeds, young roots, tender shoots, small underground stems, as well as some filamentous algae and various insects, mollusks, water earthworms, zooplankton, etc. The first-year fry can grow to 50 grams in two months and 100 grams in three months. The 50-gram fish of the previous year can grow to 250 grams in three months. Carp fry are easy to produce and easy to breed and raise, so they are ideal for rice field fish farming. Grass carp can also grow in shallow water and eat various weeds. Grass carp species are mainly raised in rice fields to provide large-sized fish species for ponds, lakes, and weirs. The first-year fry can grow to 50 grams in two months. Tilapia is not only suitable for shallow water life, but also can withstand high temperatures, is omnivorous, and can eat a lot of algae. It is more suitable for stocking in late rice fields. However, since tilapia is a tropical fish, it is not suitable for stocking in cold fields and it is difficult to survive the winter. It is not widely promoted at present. Crucian carp is generally suitable for shallow water life, omnivorous, easy to produce fry, and good meat quality.
