Everyone knows that high-density farming can raise 60,000 kilograms of fish in one acre of land. Some people ask how many kilograms of fish can be raised in one acre of land? In addition, some people want to ask about the method of raising grass carp at high density. Do you know what is going on? In fact, how many kilograms of fish can be raised in one acre of fish pond? Let’s take a look at how many kilograms of fish can be raised in one acre of land? Hope it helps everyone! High-density breeding can raise 60,000 kilograms of fish in one acre of land

1. High-density breeding can raise 60,000 kilograms of fish in one acre of land: How many kilograms of fish can be raised in one acre of land?

It depends on what kind of fish you plan to raise. Different kinds of fish require different amounts, and the mantissa of each acre of water surface is also different.

One acre of water surface, two meters deep The water can support 1,500 fish, 900 grass carp, 300 crucian carp and carp each!

2. High-density breeding of 60,000 kilograms of fish per acre: methods of high-density breeding of grass carp

The silt in the pond where grass carp is mainly raised should not exceed 20 centimeters, and the water source should be sufficient and the water quality should be sufficient. Okay, the depth of the pond should be 2 meters. A pond of 30-50 acres must have a set of 2.2 kilowatt aeration equipment. High-density fish farming.

Grass carp must be neatly sized and healthy, with a size of about gram/tail. The size of other matched species, especially carp, must not be larger than grass carp.

Grass carp stocking: In ponds that mainly raise grass carp, the amount of grass carp stocked should be controlled at about 60% of the total stocking volume. In ponds with good conditions, one tail of grass carp can be stocked per meter, along with silver carp tail, bighead carp tail, and carp tail (if carp is stocked, crucian carp cannot be stocked). If crucian carp is stocked, one tail will be used.

The following are the daily elements to prevent fish diseases

Thoroughly clean the pond: Before stocking, the pond must be filled with 80 kilograms of quicklime per meter. Round high-density breeding pond.

Fish fingerling disinfection: Soak the fish fingerlings in 3%-4% salt water liquid for 15 minutes before stocking. You can also use 10 ml/kg, 8 ml/kg copper, etc. for disinfection. How many grass carp fry should be released in one acre of field?

Feed disinfection: From June to September, disinfect the food court every 15 days. The method is to dissolve the fish in water after eating and spread it around the food court. Hanging bags and hanging bags can also be used. Basket style.

Limit food intake: Grass carp is greedy. As long as the environment is suitable, its appetite is basically uncontrolled. In the high temperature season, the food intake of grass carp must be particularly limited. Generally, it is enough to feed it until it is 80% full. Grass carp cannot be allowed to eat at night. Every day Be sure to remove the remaining material.

Water quality disinfection: from May to September, it must be disinfected every 15 days.

The number of pond culture species is entirely up to you, there are many Fish can be kept together! As for the yield, it depends on the variety and density of your stocking. Different varieties and different stocking densities have different yields!

1. When selecting fry, you need to choose high-quality fry with strong physique and strong vitality.

2. Look at the group pigments of the fry. The population of high-quality fry has the same color, no white dead fry, and the body is clean and slightly dark blue. The population of inferior fry has different pigments, is flower-colored, and has a black and gray body.

3. To see how the fry swim, use your hands or a wooden stick to stir the water into a vortex in the fish basket. High-quality fry will swim against the water to the side, while inferior fry will swim in the middle and swim with the current. How many kilograms of fish can be raised in one acre of fish pond

Those that float away are of high quality, and those that float away with the wind are of inferior quality. You can also slowly pour out the water in the plate. The fry with their backs facing upwards, the tail curled into an arc and moving back and forth are of high quality, and the fry that are close to the bottom of the plate and do not move are inferior. Get rich through high-density fish farming in flowing water.

Hello, generally no more than one acre of fish pond can be raised tail fish. However, it is also divided into fish species, such as grass carp, which is mainly stocked in 1 acre - grass carp and silver carp tail. 50 carp. You can feed grass carp pellets without making them too dense.

2. Under pond breeding conditions, grass carp are generally stocked with fish species weighing 0.25 kg. After 4 months of rearing, they can reach a size of 0.5-0.75 kg in the autumn. If they are stocked with 0.5-0.75 kg, they can grow to 1.0-1.5kg.

Silver carp and bighead carp are generally released as first-year-old fingerlings with a size of 12-8 cm and can reach 0.5-0.75 kg when they are released from the pond. Other fish such as carp, crucian carp and bream are all stocked with one-year-old fingerlings with a slightly thinner density and a size of about 12-14 centimeters.

At the same time, water body disinfection is carried out, and medicinal baits are taken orally for prevention and control.
