If you are a fish farmer, what should you pay attention to during fish farming

1. Diversification of fish pond shapes: fish ponds are often rectangular and pit pond shapes, so as to give full play to the three-dimensional benefits of aquaculture water bodies. The area of a single fish pond is generally about per hectare (mu, the same below), the depth of the pond is meters, and the length and width ratio is 5:

3. The slope coefficient is 2-3. The construction shape can be easy and then difficult, and make some transitional fish ponds, such as "back" type, high and low type, "well" type, "field" type and other shapes, among which the "back" word fish pond is the most ideal transitional fish pond.

2. Timely supporting drainage and irrigation system: the drainage and irrigation system is required to be synchronized with the construction of fish ponds. In the planning and design, the location of the drainage and irrigation ditch should be reserved.

In the specific construction, the focus is on the construction of the branch canal and bucket canal of the shaped fish pond. The main canals, trunk canals and drainage ditches can be simplified and left for construction when the works are fully completed. In terms of building form and materials, brick and stone materials can be used for open channels, positioning and stereotyped channels, and earthen ditches are used for unpositioned and unshaped channels.

The best thing to do is to use a barrage made of steel, and the basic requirements are to be able to stop (fish), flow (water) smoothly, and resist (wind and wave) impact.

3. Guarantee energy and power supply: the engineering construction of each hectare of fish pond as a production unit, according to the technical and economic index requirements of the design yield of 750 kg: the total power per hectare is 1 kilowatt, equipped with a kilowatt aerator, and the power is 13 kilowatts; 1 axial flow pumping station with a diameter of 30 cm, and 3 submersible pumps with a diameter of 15 cm and a power of kilowatts.

In this way, it can be guaranteed that in the high temperature season of the month, about 1 5 of the water in the pond can be exchanged every day, so that the quantity and quality of the pond water meet the needs of fish growth.

4. Scientific selection of breeding mode: for the newly opened fish pond, due to the light water quality, it is advisable to choose the breeding mode of herbivorous fish, supplemented by omnivorous fish, and appropriate breeding of filter-feeding fish. The stocking amount is 1 6 per unit of the design yield, and the average size of the fingerlings is about kilograms.

The ratio of various fish is: grass carp, bream: carp, crucian carp, carp

The ratio of silver carp and bighead carp is 4:4:2, and a small amount of herring and mandarin fish (5-10 per hectare) are raised.

Fish species should be based on grass carp breeding mode, 2500 grass carp summer flower fingerlings per hectare, 500 tuantou bream summer flowers, 1000 silver carp and bighead carp summer flowers, 100 carp and high back crucian carp summer flowers; It can also be the main carp species, stocking 3,000 carp summer flowers per hectare, and raising 1,000 grass carp, bream and silver carp, bighead carp, crucian carp and other fish summer flowers.

Water quality management, disease prevention, feeding management.

Fish first raise water, the water is good to raise the fish naturally it is easy to raise, a tank of new water to be oxygenated for a week to release the fish, and at the beginning of the fish best not to put more, put some good fish, aquarists called the tank fish, after the situation of these fish stabilized, it also proved that the water in the tank was stable, and then put other fish. And the density of the fish is not large, especially for novices, often like to the fish market to buy their favorite fish at once and put them in a tank to raise, so there are many disadvantages, a small density of a large fish in the tank needs a large amount of oxygen in the tank, large amount of defecation, so it is easy to deteriorate the water quality, resulting in dead fish. Then there is the need for different kinds of fish water quality is different, maybe your water quality can meet the requirements of one or two or three kinds of fish, but not meet the requirements of other fish, then other fish will get sick, and then infect, resulting in dead fish.

For example, if a fish gets a disease, but it is immune to the disease, so it will be fine, but other fish may not be immune to the disease, so it will cause other fish to die. This is the reason why many friends who have raised a lot of fish are originally very cautious in raising their own fish, but after buying new fish into the tank, their original fish will die. Therefore, the water should be raised first, and then the fish should be released, and the new water must be dried in the container for at least two days before it can be changed, prevention is better than cure!

Finally, I have to give some advice to the landlord that fish are actually the same as people, and they should try to eat regularly and quantitatively, and don't feed a lot at once if they want to feed it, feed it several times a day, and be hungry for several days if they can't think of it. Although the fish will not die of hunger for a few days or even more than ten days, if you want to raise the fish well, it is better to feed it every day, try to do it in the morning or noon, not to feed it at night, and the amount of feeding is not too much, the fish can not eat it enough, the remaining bait will pollute the water quality, the fish will eat more and the amount of defecation will increase, and it is easy to deteriorate the water quality, so try to be in line with the principle of "feeding less and eating more" to ensure that the bait can be eaten every time. Also, all animals are the same, always in a semi-starved state will be spiritual, will be willing to grab food, feed too lazy to move, in order to make your fish more energetic, don't always feed too full.

Prepare the necessary equipment, a fish tank, a net fishing, a bag of fish food and a bag of sterilized salt;

After preparing the necessary equipment, you can now go to the fish market to buy your favorite fish, and generally pay attention to when choosing fish: 1. There are no detailed external injuries to the fish's eyes, head, scales, tail and other places; Second, when fishing for fish, choose fish under the water, these fish generally swim faster; 3. Fish that are relatively normal to the naked eye;

Attention should be paid to the water for fish farming: the tap water for general household use is OK, but there is chlorine in the tap water, we need to use a fish tank or other basin filled with water to fill the tap water and let it stand for at least 24 hours, and wait for the chlorine in the hand to volatilize, so that it is healthy;

Put the fish in clean water, and sprinkle a little fish with sterilizing salt to sterilize the water;

Pay attention to the feeding of the fish, the fish is not afraid of hunger but not full, if you keep feeding the fish will keep eating until you die, feed the fish normally about 2-3 days on the line;

If you have a small fish tank, raising too many fish will cause oxygen in the water, if you buy a small air pump for fish farming, it is the best;

For the first time to buy the fish, pay attention to the water should not be changed for 2-3 days, and can not be fed;

The water change of the fish is about to change once in 5-7 days, and the feeding should be fed once in 3-4 days.

It is best to use soda water for cleaning the fish tank, and if there is no Taisho Tour, you can use clean water or tap water to roll off, and you must not use soap or dish soap to clean.

If you find that there is an abnormality on the body or head of the fish, or white spots or yellow spots, it may be that there are too many bacteria in the water, and you should sprinkle some sterilizing salt on the abnormal parts, and change the clear water in time;

If you can pay attention to the above points, fish farming will not be a problem, I hope it will be helpful to novice fish farming;
