Knowledge of fish farming is a must. Many people will keep pets at home, and many of them will raise fish, which will not only beautify the environment at home and make people feel more comfortable, but also play a role in making money in geomantic omen. The following is the essential knowledge of fish farming.
Complete knowledge of fish culture 1 1. Fish culture knowledge-fish culture method
1, select
If you choose any kind of fish, you should choose a fish with a broad and strong body, a complete chest, abdomen and caudal fin, and a wide tail. Fish without dorsal fin should have a smooth back without dorsal fin fracture or nodule. The colors of fish should be red and delicate red, white and pure white, blue and blue, black and dark, with harmonious colors and meticulous markings. Only those with blue can be called Wuhua.
Some fish are half red and half black, or those fish with red bodies and black fins are beautiful at the moment, but they will soon become all red, so you should have a hunch.
2. Health status
See if there are parasites on the fish body surface, such as long white hair and white spots, bleeding and ulceration.
Step 3 choose the age of the fish
The life span of wild fish is mostly 4-6 years, and 2-3 years is the best age for ornamental fish. At this stage, the fish are healthy and can swim freely. It belongs to an old fish after 4-6 years. Its body color is pale, it is lazy to swim, its appetite is weakened, and it is easy to get sick.
However, fish within 6 months are difficult to raise because their physical development has just begun, their species characteristics are not obvious, their colors are not set, and their defective rate is high, and they are limited to family farming.
Therefore, it is most suitable to choose 6- 18 months old fish. At this stage, the fish has a strong appetite, swims freely, the species characteristics initially flash, and the price is reasonable, so it can be kept at home for 2 years.
Step 4 feed
No matter what shape the synthetic feed is, its ingredients must meet the needs of fish growth. Good fish feed ingredients should include: protein not less than 40%, crude fiber not more than 4%, crude fat not less than 4%, and natural astaxanthin, spirulina, water pollution fungi, vitamins and trace elements should be added. And pay attention to the shelf life when buying, and choose a regular manufacturer.
Second, fish culture knowledge-fish culture water
Tap water should never be used to raise fish. Pouring tap water into the bottle for at least three days will reduce the chlorine content in tap water and reduce the harm to fish. As for changing water, use a small hose to suck the fish excrement and leftover bait out of the fish tank on time every day, and then add the same amount of water.
Third, the knowledge of fish farming-the number of fish farming
From the perspective of geomantic omen, the number of family fish farming is small, but the key is the appropriate number. This will limit the effect. In general, it is better to have one, four, six, nine or four numbers at home. Because in Feng Shui, 16 is water and 49 is gold, these numbers are the most popular.
Four, fish culture knowledge-fish culture Feng Shui
1 The orientation of fish culture depends on the orientation of the house, and the location of the feng shui fish tank is also different, as follows:
(1) Sit facing south, suitable for the north, northeast and southwest;
(2) Sitting east facing west is suitable for northwest and east;
(3) Sitting south facing north is suitable for the northeast and south;
(4) The west faces east, and it should be placed in the southwest and northeast;
(5) Sitting in the northeast facing southwest is suitable for facing north and east;
(6) Sitting in the southeast facing the northwest is suitable for the northwest west;
(7) sitting in the southwest facing the northeast is suitable for the northeast;
(8) Sitting northwest facing southeast is suitable for things.
2. According to the specific space of the house, the locations suitable for placing fish tanks are as follows
(1) porch: It can relieve the suffocation of going straight to the gate, prevent the exuberant leakage of the mansion, and have the function of making money.
(2) living room: there is water in the living room, which can play the role of "collecting gas" and make the room more lively. The fish tank in the living room can be placed in the financial position of the living room, which is the diagonal position of the door.
(3) Study room: Wenchang can be upgraded to intelligent water, which can bring books transportation and help students and candidates.
(4) Unit lobby: The fish tank is placed in the company lobby, which is conducive to resolving external shocks.
(5) Meeting room: It can ease the atmosphere of the meeting. If placed in the southeast corner, it can enhance Wenchang qi and become a smart water.
Basic knowledge of fish culture II. Fish farming needs water first.
1, fish tank disinfection.
Fill it with water, pour in sterilized and deoxygenated water, soak it for 20 minutes, and drain it.
2. Clean and decorate.
Landscape sandstone is washed with clear water. The simulated plants are soaked and cleaned at 80 degrees Celsius before use.
3. Square landscape.
Can be placed according to our leisure, or DIY at will.
4. pour tap water.
The watermark is added above the water pump.
5. Add water stabilizer.
According to the dosage, stabilizer is added to stabilize the PH value of water and purify the water quality.
6. Add nitrifying bacteria.
After 2 hours, nitrifying bacteria were added.
7. Filter the water quality.
The filter runs for 2 days.
8. release water to raise fish.
In the fish tank, stir the water in the tank three or four times, then fish and put it in the fish tank.
9. Observe.
After putting it in, observe the fish's condition to see if there is rot or scratches on the surface, so as to buy fish medicine in advance and prescribe the right medicine.
10, feed the fish.
After releasing the fish for three days, the fish should be properly fed after adapting to the environment. Unhealthy fish may die and should be fished out in time.
Second, the fish tank is complete.
1, water level.
The water level of the new fish tank should be increased to a distance of 1 cm from the edge of the fish tank, and the water level should be checked frequently. If the water level is lower than the filter pump, the evaporated water should be replenished in time. (Filter pump is easily damaged by dry burning)
2, filtration cycle.
Check whether the filter pump works normally (it is normal for the filter pump to occasionally make a sound of pumping water). If the filter pump does not work, there may be something stuck or blocked in the internal shaft. Just dismantle it, debug and clean it up.
Step 3 feed.
Feed 1 2 times a day. Let the fish finish eating for 3 to 5 minutes.
4. Water temperature.
For example, keep tropical fish, check the water temperature, and keep the fish at a proper temperature (22 to 30 degrees). Check the health of the fish to see if they are sick.
5. Change the water and clean it.
Remember to cut off the power supply when changing water, change water once or twice a month, and clean the filter cotton once or twice a month.
6. Fish tank Do you need a heating rod to raise tropical fish in winter?
The suitable water temperature for tropical fish is 22 to 30 degrees. So in very cold winter, it is necessary to prepare a heating rod for fish.
7. Observe.
Observe the state of fish when feeding feed every day, such as eating less and swimming slowly. The crowd pushes or the water is turbid, which is the initial state of fish getting sick. At this time, half of the water should be replaced immediately, and more salt, yellow powder and fish medicine should be added for 3 days.
Sharing of fish culture and feeding experience.
1. When feeding the feed, if the fish is not finished within 5 minutes, remember to remove the residual bait immediately, otherwise it will pollute the water quality.
2. Observe the health status of the fish every day to see if the fish's activities are healthy and lively.
3. When changing feed, stop feeding for 2 ~ 3 days. Then mix the previous fish feed with the new feed, and don't change the feed when the fish is sick.
Essential knowledge of fish farming 3. First, novice fish farmers should buy cheap and improved varieties.
Experience is accumulated little by little. If we start with the expensive and difficult-to-raise varieties, once the fish die because of some mistakes, it will be a great blow to enthusiasm and self-confidence. Novices are advised to buy some common commercial fish in the market, because these fish are easy to raise, and they can gradually accumulate experience from the process of raising these fish.
Second: choose the right fish tank.
Fish farming must have a fish tank. If you use a washbasin to raise fish, it is inconvenient and unsightly. Before buying a fish tank, you must think clearly about your future fish farming plan, so as to buy the most suitable fish tank.
If you just want to keep a few fish for viewing, then a small fish tank can meet your requirements. It is more important to buy a bigger fish tank if you want to mix ornamental fish in the future.
Third: learn to raise water before raising fish.
Never buy fish before you consider how to raise water. Compared with other pets, fish is very fragile, and a little change in the environment may lead to a large number of deaths. Therefore, before raising ornamental fish, you must master the basic knowledge of water conservation, which is the most basic.
Fourth: the newly bought fish should adapt to the "new home" a little.
The newly bought fish must not be directly thrown into the new fish tank we have prepared. We can put the plastic bag containing fish into the fish tank first, and then slowly release the fish when the water temperature in the plastic bag becomes similar to that in the new fish tank. Don't throw away the water containing the fish you just bought. These "old waters" are the key to make the fish adapt to the "new home" quickly.
Fifth: Don't overeat.
I'd rather let the fish starve for a while than feed them too much. A little Russian fish won't die, but if you are full, you will really die. Moreover, excessive feeding will also affect the water quality, but will affect the normal living environment of fish.
