How to do a good job in daily feeding management?

Whether it is productive farming or ornamental farming, daily management is an indispensable work in goldfish farming. Even if goldfish are raised in an automatic aquarium, attention should be paid to whether the fish's activities are normal, and accidents caused by environmental changes, changes in the physiological state of fish or mechanical equipment failures should be dealt with in time. Daily aquaculture management mainly includes the following aspects:

(a) the location of the aquarium

The place where the breeding containers are placed should not only take care of convenient management, suitable light and temperature, but also serve as an indoor landscape. But the first thing is to consider the convenience of management, which is beneficial to the life of fish. Therefore, it is ideal to put the aquarium in the south window, followed by the east window. To prevent strong direct sunlight, when the sun is strong, use curtains to shade the fish, otherwise, the fish will get sick and even die over time.

(2) Feeding procedure

(1) Preparation of containers. First, clean and disinfect the aquarium, then spread sand and gravel, plant aquatic plants, and slowly add water that has been dried 1 ~ 2 days in advance. Tap water should be aerated for 24 hours.

(2) Put the purchased goldfish together with plastic bags into the water in the upper layer of the aquarium. When the water temperature in the bag is close to that in the aquarium, throw the water in the bag out of the aquarium and put the fish in the bag into the aquarium.

(3) After the fish in the aquarium adapt to 1 ~ 2 days, a small amount of bait can be put in, and the amount of bait can be increased to the normal amount day by day.

(4) Newly purchased individuals who need to be released are pre-cultured in another container for 7 ~ 10 days, and whether they are carriers or not is observed. If it is determined to be a healthy fish, it can only be raised with the previously released fish.

(3) stocking density

Goldfish have a certain clustering habit, especially in the breeding season. Reasonable stocking density is beneficial to the bodybuilding of goldfish and the sanitation of water environment. The stocking density of goldfish varies with species, age, individual, season, water temperature, bait status, still water or living water, deep water or shallow water, etc. It is better to be sparse but not dense, so that fish can be strong and show the unique richness of special species. If the animals are kept too close, their heads will float up due to lack of oxygen, and even get sick or die. If 5-6 second-instar fish can be put in an aquarium glass box with a length of 60cm, a width of 30cm and a height of 35cm, if an air pump is installed in the aquarium, the stocking density can be increased to 10- 12.

(4) Feeding

Feed regularly and quantitatively. Because the number of goldfish raised at home is small and the consumption of feed is not large, it is best to feed active bait, such as Daphnia and earthworm. For young fish that have just started to eat, it is best to feed single-celled protozoa (such as paramecium). ). If you can't buy it, you can use Daphnia instead.

When feeding, be sure to keep the water clear and regular. Feed 1 ~ 2 times a day, that is, once in the morning and once in the evening. And it's early at night, so you have to feed it when you get home from work. If the weather forecast shows that there will be showers or cooling at night, the feeding amount should be reduced or not, and the feeding time in the morning can be before 8 am. The amount of bait should be within one hour at a time. At the same time, we should refer to the shape and color of feces to judge whether goldfish is well digested. In general, the feeding situation of goldfish should be observed within one hour of each feeding, so as to determine the next feeding amount.

(5) Change water

Although goldfish containers are often cleaned, they cannot be completely cleaned. Over time, the decorations in the container are dull, the sand and stones have turned yellow-brown, and the cracks on the inner wall of the glass jar have accumulated black rust and odor. It is necessary to clean and change water thoroughly. The conventional methods are as follows: ① Use a rubber hose to suck the clear water in the upper part into a clean container for later use, and the turbid water in the lower part will be treated later. (2) Take out aquatic plants, stones and other ornaments, and rinse them with clear water for later use. ③ Take the fish out with a net bag, and cover the net bag properly to prevent the fish from jumping out of the net bag: put the fish into the fresh water that has just been sucked out. (4) Take out the discolored and smelly fine sand, wash it and rub it until there is no peculiar smell; If it is possible to replace new fine sand, it would be more ideal. ⑤ Thoroughly clean the container, and wipe the rusty spot and container wall with decontamination powder. If not, you can dip a clean cloth in vinegar, and then wipe it repeatedly on the container wall until the glass or porcelain cylinder wall is clean. The pollution caused by fish excrement and food residues often exceeds the self-purification ability of water bodies. Even in a closed water circulation system with filtration equipment, organic impurities will accumulate in water due to limited filtration capacity. In this case, the most effective way to remove pollutants in water is to change water.

It is not advisable to update all the water supply every time the water is changed. Generally, it is appropriate to change the raw water quantity from 1/5 to 1/3. When changing water, it is best to use siphon to suck the old water at the bottom of the pool together with organic pollutants, and then inject new water. Pay attention to the change of water temperature when changing water. Fish is a temperature-changing animal, and its body temperature needs to be maintained by the ambient temperature of water. Once the water temperature exceeds its suitable temperature range, fish will be hurt in a short time. Especially in hot or cold seasons, we should pay more attention to the harm of rapid changes in water temperature to fish. Even if it is an aquarium equipped with thermostatic equipment, the reliability of the equipment should be checked.

When goldfish will move into a new water environment, it is necessary to pay attention to the temperature difference between the old and new water bodies, so as to prevent fish from dying because they do not adapt to the rapid change of water temperature. For example, people usually use plastic bags filled with water as transportation tools to transport goldfish bought from markets or shops home to raise them. At this time, it is best not to pour the goldfish in the plastic bag into the aquarium first, but to soak the plastic bag with hairtail in the aquarium for a period of time. It is safer to put the goldfish in the aquarium when the water temperature of the aquarium is close to that of the plastic bag.
