How to raise fish in summer? How to raise good fish in summer

Feed 2 meals a day, around 8 a.m. and around 6 p.m.

3 goldfish of 5 cm, feed about 7 grains per meal, a total of 20 grains per meal is enough, 40 grains a day.

They are fed nutritious animal feed and white sesame seeds. Animal feed such as daphnia, earthworms, mealworms, green worms, skin worms, etc. The main feeds are earthworms and white sesame seeds.

Both red and black earthworms can be fed. It can be fed with raw white sesame seeds. White sesame seeds are readily available.

Goldfish are very fond of eating, easy to digest, and do not easily pollute the water. Do not feed low-quality goldfish feed that you have bought. Because this feed has too much starch, poor nutrition, is not easy to digest, and the water quality is easy to pollute, goldfish eat malnutrition, goldfish growth is relatively slow, and it is easy to get sick.

As long as the goldfish eats easy-to-digest food, it will not die.

When to feed, generally once a day in the morning and afternoon, it is not advisable to feed more, until it is eaten. Otherwise, it will pollute the water quality.

2. Light: It is best to put the fish tank in the sun.

Shoot for 1-2 hours in place. In this way, the sun's ultraviolet rays are used for sterilization. It plays a role in disease prevention. This reduces the number of diseases. Try to prevent fish diseases as the main thing, supplemented by medication. At the same time, due to photosynthesis, the color of the fish body is also relatively bright and beautiful.

3. Water change: Frequent water change can increase the dissolved oxygen in the water. When changing the water, you can only change one-third to one-quarter, and you can't change a lot at once, and the fish are not adaptable.

It is important to keep the water in the aquarium clear. Fish with sufficient dissolved oxygen in the water can grow and grow quickly. Otherwise, it stops growing or even dies.

When to change the water, there is no conclusive conclusion, it can be determined according to the water quality, the water quality is turbid, otherwise it is less changed.

First of all, you have to have a container for raising fish, fish tank, water tank or cement pool, the container has to add water, it is best not to use tap water to add directly, even if it is well water, the most important thing is to add oxygen and cooling, the oxygen pump must be larger to ensure that the oxygen in the water is sufficient; Then you have to pay attention to the water temperature, don't let the water temperature get too high, keep it below 20 and your fish will basically be able to stay overnight.

First, try not to add new fish to the tank on hot days.

Fish farming

The weather is hot, and the germs enter a high incidence period. Normally, the nitrification system in our fish tank is balanced. If you add new fish, many of the new fish are not sterilized thoroughly.

After entering the fish tank, it will cause cross-infection of viruses in the fish tank. The virus soon broke out, causing the nitrification system in the original fish tank to collapse, and the fish quickly died. So try not to add new fish in the summer, especially large ones.

Second, change the water frequently

Fish farming

The weather is hot, and the water in the fish tank is always in a hot state, and the algae, viruses and food residues in the water will make the water spoiled and smelly. We need to replace it with new water in a timely manner. Brother Xiaoyu believes that the new water can be replaced every three days or so, and the advantage of this method is that there is not much new water added, so that the nitrification system in the original fish tank is not easy to collapse.

Because it is difficult for many aquarists to dry the tap water for a few days before adding it.

Third, try to feed less fish food or don't feed more fish food.

Fish farming

In hot weather, if you feed too much, the fish will not be able to eat, and the fish food will ferment quickly within an hour or two, polluting the water quality. It makes the water smell and provides nutrients to the algae, and all kinds of algae multiply wildly.

Fourth, do not turn off the oxygen pump

Fish farming

The weather is hot, the water in the fish tank does not contain much oxygen, the fish have difficulty breathing, if you often turn off the oxygen pump because of the noise, this is very bad, you must know that nitrifying bacteria need running water to multiply quickly.

5. The temperature is high in summer, and the aquatic plants should be pruned.

Fish farming

In order to give the fish a clean environment to grow. Aquatic weed planting tank, pay attention to pruning aquatic weeds, a case in case of full sunshine, too much saturated oxygen in the water, bubbles attached to the fish, is likely to make the fish breed ** disease, resulting in epidermal ulceration.

The temperature is high in summer, and fish farming needs to pay attention to:

As the water temperature rises, it is impossible to see as much light indoors as outdoorsIt is easy to breed mold, bacteria and fish diseases

2. Dissolved oxygen. As the water temperature rises, the amount of dissolved oxygen in the water decreases, but the algae multiply and die at an increasing rate, and the water cannot keep up with the water change, and the dead algae decompose and spoil the water quality, and the algae that bloom in large numbers will compete with the fish for oxygen at night.

The water temperature increases, the fish are more active, the metabolism is faster, the feeding amount increases, and the fish feces also increasesThe cleanup is not timelyFish feces or bait residues in the fish tank will also spoil the water quality. If you are fed live bait, it will also be presentExogenous insects and bacteria invaderisk.

4. The temperature difference between the water changes is too largeFish can become sluggish, stop eating, catch a cold, or even die. So keep the water temperature stableDo not exceed 3 temperature differences

If you raise goldfish in a place with strong sunlight such as a balcony, it is easy to form green waterA slight negligence can cause scalding。In particular, it is necessary to pay special attention to raising large-tailed goldfish.

The feeding density is large, the water is old and green, and the oxygen is stopped at night, which is causedStuffy tank

Fish farming is diligent, especially ornamental fish, while obtaining relatively high profits, the risk faced by farmers will be much higher than that of ordinary economic fish. Summer is the season of fish growth, for the farmers, the hardest time of the year has come, at this time, not to take a little leisure, a little careless, often cast a big mistake, so these "diligence" can not be ignored. One is the "leg work", high temperature in summer, the increase of plankton in the water body, and the increase in the amount of fish body feeding and excretion, so the water situation of the pond changes a lot, so it is necessary to often inspect the pond, pay attention to the water color, pay attention to the transparency of the water body, detect the dissolved oxygen in the water body in the early morning and evening, and see if there is a situation of the floating head of the fish body, and take corresponding aeration measures in time.

The second is "hand diligence", most of the quality of a year's breeding results is determined by the summer culture, therefore, regular net casting or net proofing is essential, according to the proofing results, you can adjust the feed nutrition level and breeding density, in order to achieve a reasonable water fish load. In addition, frequent sampling and measurement of water quality is also an important part of the management of aquaculture. In ornamental fish farming, it is necessary to continuously screen high-quality seedlings, and in the first month of summer, we must pay close attention to picking fish, which not only reduces the pressure of breeding, reduces costs, but also provides a broad space for the growth of high-quality seedlings.

The third is "mouth diligence", ornamental fish breeding process, inevitably problems, when there is a situation, and peer exchanges, to the master for advice is particularly important. First of all, when encountering common problems, the word experience is no match for the word, so asking diligent questions is the last word in raising good fish. Secondly, don't work behind closed doors, grope for more detours by yourself, sometimes a word from others may save you a lot of financial and material resources.

Finally, it is very important to inquire diligently, understand the market, choose the right breed, and have a long-term plan, is the key to the success of ornamental fish farming, to obtain profits.

There is no problem with raising ornamental fish in summer, but it is a big problem in winter; In the summer, just remember to change one-third of the water the next day.

Almost all tropical fish can be as long as your tank is big enough, but novices should consult aquarists, which is easy to start with, don't ask the merchants, which merchants make money and sell which.

The flora in the tank is unbalanced, and there are more fungi in summer! It is recommended to improve the structure of the microflora! The easiest and intuitive way is to make the water green, introduce the easiest way to make green, go to the fish market to buy redworms and put them in the tank, take them out after 2-3 days (they may also be eaten by goldfish), and then replace them with new redworms, repeat for a week, and the water will turn green!

Goldfish love "old water"! If your goldfish eats red worms, be careful when you put the worms in to avoid holding the goldfish!

Summer is coming, how to feed the koi well.

When the water temperature rises to about 25 in summer, you should thoroughly clean the biochemical filtration system of your favorite carp pond. After cleaning, the pool water is easy to turn green due to the change of the proportion of bacteria, so it is necessary to turn on the ultraviolet germicidal lamp to avoid the pool water turning green. In about two weeks, you will be able to turn off the UV lamp.

Circulate filtered water to an hourly cycle, and turn on the oxygen pump at full speed from 21:00 p.m. to 06:00 a.m. the next morning.

Cover with a shade net above the carp pond, and the covering area depends on the depth of the water and the intensity of the sun exposure in your carp pond, which generally accounts for about one-third of the area of the carp pond. The bottom water of the sinking hall bin and the first biochemical bin in the filtration system should be discharged once a day, and the bottom water of the second biochemical bin and the clear water bin should be discharged once a week every other day. 24 hours of uninterrupted infusion of fresh water like the diameter of a ballpoint pen.

Once a week, the ore powder should be withdrawn to the Ai Lichi pond, and about 50g of stone powder should be put per ton of water.

Feed germ type and color type fish food, the ratio is 2:1, and the feeding amount is controlled to be eaten in about 10 minutes. Feed nutritious fresh silkworm pupae two to three times a week.

Note that the amount of silkworm pupae fed is about two to three silkworm pupae per fish, and do not overfeed. Every 10 days, stop feeding the carp for one day, and only feed chopped Chinese cabbage and a small amount of germ fish food on the first day of re-eating. Once a month, on the day of stop feeding, the whole pool is sprayed with 90% crystal trichlorfon at a dose of 1 ppm.

Tropical fish farming method There are many species of tropical fish, and the essentials of breeding mainly include: 1. Water 1Water quality Captive-bred tropical fish require soft water or low hardness water, and the pH is weakly acidic or neutral.

Tropical fish are more acidic, have difficulty breathing, and grow slowly; The alkaline nature is strong, and the gill tissue of tropical fish will be corroded. 2.Water change (1) Partial water change is to use a straw to suck out feces, bait residues and other dirt at the bottom of the fish tank.

The water absorption should be 1 4 of the water in the tank. Then, add the same amount and temperature of new water that has been dried or chemically dechlorinated. The frequency of water mixing should be 2 times a week in autumn and winter, and 3 times a week in spring and summer.

2) All the water should be changed All the equipment in the fish tank should be taken out, the aquatic weeds and fish should be fished out, placed in other containers at the same temperature as the raw water, and the wall and bottom of the tank should be scrubbed clean with a sponge. Change the water every 3 months and 4 months. 2. Water temperature Tropical fish are extremely sensitive to temperature, and if the temperature is not suitable, they will die quickly.

Different species of tropical fish have different water temperature requirements. The water temperature for most tropical fish is 20 24 and 25 28 during the breeding season, and the temperature difference between day and night should not exceed 4. 3. Oxygen A certain number of aquatic plants should be planted in the fish tank, because aquatic plants will produce oxygen during photosynthesis, so that the oxygen content in the water increases.

At the same time, timely removal of dirt and frequent water changes can also increase the dissolved oxygen in the water. 4. Light Place the fish tank in a sunny room, and it is best to receive about 1 hour of sunlight in the morning and evening when the sun is insufficient; If you set up a fish tank in a room without sunlight, you should use a light to illuminate the aquatic plants, using a 60-watt incandescent bulb or a 40-watt fluorescent lamp for 6 hours a day. Light can make tropical fish grow faster and make their bodies more colorful.

5. Stocking Tropical fish are raised in tanks, and the stocking density depends on the size of the fish tank. For first-time fish farmers, the lower the density, the better, and the addition of an inflator pump is required. For the combination of fish in the same tank, quiet fish cannot be polycultured with aggressive fish; Large fish cannot be polycultured with small fish.

There are a variety of options for tropical fish feed, such as fish bugs, bloodworms, or packaged feeds suitable for different species of tropical fish. Both raw and live bait should be washed to control the source of the disease.
