How to tell if the fish are full or not?

In the process of raising ornamental fish, it is believed that a large number of fish friends can not make a correct judgment on how much fish to eat, so that the fish are hungry when they are full, the growth rate is not ideal, and diseases occur frequently, which will also make the ornamental effect of the fish unsatisfactory. So how to tell whether the fish is full or not?

Fish live in the water, it is not easy to observe the eating situation, and some fish are very gluttonous. If they do not master certain scientific methods and do not understand the water environment and the feeding habits of fish, they will not be able to correctly grasp the feeding quantity of fish. Here are some suggestions for you.

First, the judgment that the fish are hungry and full.

one

Look at the length of time to eat.

It is normal to finish eating in about 10 minutes after feeding. If the feed is eaten up immediately, it can only mean that it is not enough. If some fish are not full, you can also feed a small amount of feed again, or increase it appropriately in the next feeding. If the feeding time is extended to 30 minutes, and the fish have left the food market, the next feeding can be appropriately reduced. Then remove the excess fodder. If the excess fodder is left in the tank all the time, the fish will not eat it. I believe that people will not like to eat food that has gone bad after a meal. And these residual fodder food will be decomposed and produce some substances that are bad for the fish and even turn into toxins, so do not let these residual food pollute the living environment of the fish!

two

Look at the growth size of fish

Every summer, the intake of young fish will increase day by day after eating, and the change of each period of time should be observed in the feeding plan of one week or ten days. If the amount invested is the same every day, it will be eaten within 10 minutes at the end of the week or at the end of the decade, indicating that the weight of the fish has increased, and it can generally be seen visually. The young fish grow into big fish and the food intake is also gradually increasing. Please refer to the previous 1 to increase the feeding amount.

three

Look at the movement of the water.

Especially after feeding, if the fish do not get sick and move frequently on the water, this is a sign of hunger. On the contrary, after eating, the fish will leave to play, especially the young or small fish will only swim in flocks on the surface of the water, which is a sign of severe hunger, commonly known as "horse racing disease". You should immediately feed and stop swimming, otherwise a large number of fish will die. if the fat water fish that mainly feed on plankton, you can observe the fat and thin water quality to determine whether it meets its growth requirements. When the water quality is thin, fertilizers are used to cultivate plankton; when the water quality is too fat and there is a lack of oxygen, it is necessary to immediately change the water to increase the amount of oxygen, and if necessary, sprinkle trichlorfon and other insecticidal drugs to kill zooplankton, which is conducive to its growth.

Second, prevent the imbalance between hunger and food, and make sure that there are four levels of feeding.

You can't vote what you have, how much you have, and don't vote if you don't have it. A fish proverb says, "if you stop eating for one day, you will grow for three days." Some fish lovers may not pay attention to the normal feeding of ornamental fish when they are busy at work, and some stop eating for as long as a few days. Or use the feeder to concentrate the feed on a small area, especially in the case of group breeding, resulting in uneven eating and uneven growth of fish, which will affect the healthy growth of fish. The feed after opening must be kept tightly and stored in a cool and ventilated place. If the feed has become moldy, it must not be fed again. Moldy feed will lead to disease or even death of fish. Therefore, in order to learn the technology of scientific fish culture, we must first learn to identify the hunger and satiety of fish and adhere to the "four-fixed" feeding method of quantity, quality, positioning and timing, so that we can raise fish well and make a lot of money.

That's all for today. I hope I can help you. If there are any deficiencies, I'd like to give you some advice.
