What are fish farming techniques? Tips on how to raise fish

Pit pond fish farming skills".

Pit ponds, also called pit ponds, are widely distributed in rural areas and suburbs, and can be used to raise fish. The advantages are: small capacity, less water consumption, easy to solve the water source; The dry pond is easy, easy to clean, easy to raise, easy to catch, and does not require special tools and equipment; It can be organically combined with agriculture and animal husbandry, and it is easy to solve bait, fertilizer and labor; The production is flexible and diverse, and it is suitable for raising fish, raising seedlings and breeding.

The techniques are described below.

1.Cleaning of potholes. It is necessary to communicate the water source and divert the water through channels or culverts; The pool is neatly shaped, long and square; use of terrain to lay simple drainage pipes; leveling the bottom of the pond and tilting it to the drainage side; The walls of the pool should be compacted or coated with triple soil to prevent leakage.

Fish are sterilized with quicklime before releasing them.

2.Fingerlings stocking. For the pit ponds with abundant water sources and can raise fish in live water and semi-live water, grass carp and carp are stocked, and 15 20 fish fingerlings of more than 17 cm are stocked per square meter.

For pits and ponds with water sources supplemented but not abundant, it is advisable to mainly use silver carp and bighead carp, with grass and carp. Each square meter of water surface can put 80 100 silver carp of 3 10 cm, 8 10 bighead carp, 10 15 grass carp of 13 17 cm, and 3 5 carp of 3 cm per square meter of water surface. The "Tianshui" and stagnant water pits and ponds where the water source is insufficient and the water supply is difficult are mainly used for crucian carp, carp and tilapia.

They are not strict in their selection of water bodies. It can live in poor water bodies, tolerate low oxygen, and is suitable for stocking in stagnant pit ponds. Because the feeding habits of the three are basically the same, it is generally advisable to monoculture.

30 40 carp of 3 cm per square metre of water surface, or 1 kg of crucian carp, or about 2000 tilapia fry. If pit pond fish farming can be combined with mountain pond and paddy field fish farming, a series of pit pond flowering, paddy field breeding, and mountain pond fish cultivation can be adopted, so that grain, pigs, fish, and vegetables can promote each other, so as to improve the production capacity of water and soil (it is advisable to stocking in spring).

3.Feeding management. Flowing water and semi-flowing pit ponds based on grass and carp, grass carp are mainly fed with fresh and tender grass, vegetable leaves or aquatic plants; Carp is mainly a paste-like and granular feed made of concentrate and a small amount of vegetable leaves, or fed distiller's lees, bean dregs, boiled sweet potatoes, and potatoes.

In addition, snails, moths, earthworms, etc. can be fished to supplement some animal food with high protein content. The pit pond based on raising silver carp and bighead carp should be mainly decomposed manure, combined with grass and vegetable leaves to feed grass carp, and some concentrate should also be replenished. In the pit pond where the water source is difficult, it is advisable to feed concentrate and fertilize a small amount.

As with pond fish farming, the amount of bait and fertilizer should be insisted on less and more often. Pay attention to leakage, fill water regularly, and keep the water quality in the right color and transparency for fertilizer. Strictly prevent the harm of pesticides, water, birds, beasts, and fish diseases.

Give full play to the advantages of easy to catch pits and ponds, catch large ones in a timely manner and keep them small or make up for them, adjust the density, and promote growth.

Don't raise you before it's too late, it's like asking how to get rich.

1. Raise fish and water first.

Only good water quality is suitable for the growth of fish. Novice fish farmers, do not rush to buy fish after buying a fish tank, you need to leave the tap water for 7 to 10 days, during which you will inject some fish maintenance drugs into the fish tank, and then buy the fish fingerlings for stocking.

2. Pay attention to the selection of fish species.

Due to the different delicate degrees of fish species, different personalities, and different fish species are matched together, if the chong bush is not selected properly, they will often bite each other, resulting in the best of the fish. Therefore, it is necessary to raise fish with similar temperaments together.

3. Reduce feeding.

When feeding the fish, we must pay attention to reducing feeding, once a day, generally according to the number of fish to eat in 2-3 minutes. It is also necessary to pay attention to the density of fish farming to give the fish enough space to live.

4. What should I do if I am too lazy to change the water?

If you find that the fish tank is a little cloudy, or when there is a lot of fish feces, put in the digestive bacteria, and after 10 minutes, open the filter for another hour, the fish tank will be clean and the water quality will be better.

5. How to avoid hurting the fish?

The saddest thing about fish farming is that the fish are dead, but as long as you regularly dismantle the cherry blossoms into the fish tank and sprinkle some special potions sold in the market, these potions can play a role in preventing and curing diseases of fish. In winter, you should also pay attention to the water temperature, if it is a tropical fish, the water temperature is generally kept between 23 and 26. To heat the water in the fish tank, of course, you need to use a heating rod.

Selection of fry: Before raising fish, it is necessary to select fry that are healthy, disease-free, and responsive. Over-water delivery:

Soak the bag containing the fish in the tank, wait for the fry to acclimatize to the environment, and then release it in the tank. Feeding and water exchange: change the water once a week, the water exchange is one-third of the total, and feed once a day.

1. Select fish fry

Before raising fish, it is necessary to select the fry that are strong, responsive, disease-free and injury-free and put them in the fish tank, and in the process of selection, you can observe the head, eyes and tail of the fish, and there will be no external injuries on the healthy head, eyes and tail, and there will be no scales falling off.

2. Put it in water

In the process of putting fish fry, it is necessary to take measures to pass the water, put the bag containing the fry directly into the fish tank, let the water temperature in the bag and the water temperature in the tank be close, and then pour the water in the tank into the bag, wait for the fry to adapt to the environment, you can cut the bag and let the fry enter the fish tank.

3. Feed and change water

In the process of fish growth, the requirements for water quality are higher, and the water should be changed once a week during the breeding period, and the amount of water changed is one-third of the total amount of water, so as not to allow the fish to adapt to the environment, and before replacing the tap water, the tap water should be dried for 1 day, and the chlorine should be removed, and the fish should be fed once a day, and the amount of feeding should not be too much each time, so as not to kill the fish.

Methods and techniques of fish farming:

1. Clean and disinfect.

Before raising fish, the pond should be cleaned, which should be carried out from early winter to early spring, drain the pond water, transport away the silt, widen and strengthen the pond ridge, and at the same time carry out drug pond cleaning. Fingerlings must be strictly disinfected before being put into the pond to avoid cross-infection of fish diseases.

2. Fingerlings stocking.

Stocking fingerlings should be stocked sooner rather than later, and stocking fingerlings early is one of the experiences to ensure a good yield. Every year after the beginning of spring, the southern diqu begins to prepare for the stocking of fish fry.

At this time, the water temperature is still low, the scales of the fry are tight, and the net and transportation are not easily injured, which can significantly improve the survival rate. As soon as the weather warms up, the fish will be able to adapt smoothly to the new water environment. It should be noted that when the cold weather is cold in early spring, the fingerlings should be stocked on a sunny day.

3. Stocking density.

Stocking density is highly flexible and dependent on a variety of factors such as environmental factors, feed conditions, fingerling species and sizes. The pond conditions are good, the bait fertilizer is sufficient, the fish fingerlings are small, and the aerator and the breeding technology level is high, otherwise the stocking density should be sparse.

4. Daily management.

Frequent pond patrols to observe the dynamics of fish in the pond. Patrol the pond every morning, noon and evening, and observe whether the fish have floating heads before dawn and the degree of floating heads. In the high temperature season, when the weather changes abruptly, the fish are prone to serious floating heads, and they should also patrol the pond before and after midnight, so as to stop the serious floating heads in time to prevent flooding.

Dear, I am honored to provide you with blind lead services Fish farming can make people enjoy the sound of the water, watch the fun of fish playing, and also play a certain role in beautifying the environment. Here are the methods and tips for fish farming:1

Choose the right species: Choose the fish species that are suitable for keeping at home according to your personal preferences and family conditions. Primary pearl fish, goldfish, lotus carp, etc. are common pet fish, they require different water temperature, pH value, oxygen content, should choose suitable for their own family conditions and the most suitable.

2.Ensure good water quality: Water quality determines the health of the fish, so you should choose the right filtration equipment, change the filter regularly, and check the water quality.

At the same time, avoid overfeeding to prevent excessive organic pollutant production, and regularly replace 10-20% of the water every week. 3.Give the right amount of bait:

Feeding fish the right amount of evenly distributed feed will keep them healthy and increase their appetite. Overfeeding, on the other hand, can lead to problems such as muddy or polluted water at the bottom of the moss or pond water. 4.

Proper environmental arrangement: Aquatic plants can increase oxygen levels, reduce organic pollutants, and beautify waterscapes. The ecological turtle tank and ornamental fish tank that have been scientifically designed can make the aquarium general vivid and atmospheric.

5.Regular health checks: Regularly check the weight, texture and color of the fish, and carry out maintenance work such as water change and replacement of resident liquid and charcoal powder at regular intervals to ensure that all fish can live in a good environment.
