fish in the process of breeding is a matter of great concern. How to choose the materials, how to control the amount, when to feed, or pay more attention to some details. Selection and Feeding Method of

1. Different Feeds

Feed is very important in breeding. Feed can basically account for more than 80% of the total breeding cost. Is the choice of species, a wide variety of aquatic feed, from the shape can be divided into powdered feed, soft pellet feed, hard pellet feed and extruded feed. In terms of use, there are grass fish, carp, crucian carp, mixed nutrients, prawn, turtle and so on.

size is not the same as the fry, feeding method is also different. For example, at the beginning of feeding a catty of 100 fry, the general feeding time is 8: 00 a.m. to 7: 00 p.m. Feeding once every hour, each feeding time is about an hour. When the fry grow to only about 20 fish per catty, each feeding can be separated by two hours, and each feeding time is still about one hour. When the fry grow to only 10 pieces per catty, it is enough to feed them four times, each time for one hour. It should be noted that in the fry stage, the size of the feed should be controlled well, and it is impossible for small fry to eat too much feed. In the early stage, it is suggested to use broken materials, and when you grow up, you can throw particles. Fry on the feed protein requirements higher than the fish, feed protein requirements between 32-35.

Above are some things that should be paid attention to when feeding fish fry, and below are some problems that should be paid attention to when feeding fish when growing up.

The feeding time of general fish is controlled within 30-60 minutes, which is * * * * * * * * * * * * * * * * * * * * * * is equipped with an oxygen increasing device, which is opened 10-15 minutes before feeding to ensure sufficient dissolved oxygen in the feeding area. Then there is the feed. I have also encountered many fish that have intestinal problems caused by the feed. Check the feed before feeding to ensure that the feed particles are uniform, fresh and free from moldy problems.

Let's talk about when to add materials, when to reduce materials or even stop materials. As long as these details are done, liver and gallbladder diseases can be avoided.

For ordinary fish ponds, the usual feeding amount is closely related to the weather. When feeding, pay attention to the clear weather, when there is a slight breeze, you can throw a little, and when it is rainy, you should feed less or not. Before it rains, the weather will be muggy and there will be no wind at all. At this time, it is even more important not to feed, and the oxygenation will be turned on to ensure sufficient dissolved oxygen in the pond.

also depends on the color of the water to determine the feeding amount. The color of the water is lighter and looks clear. At this time, the water is thinner and can be fed more. If the water color looks green, there will be no dosage, and it can be fed normally. However, if the water color is dark or soy sauce color, and even the fishy smell can be asked near the fish pond, don't throw food. This is because the water quality and bottom quality have deteriorated. At this time * * * the important thing is to change the water to the bottom, turn on the aerator to increase the oxygen, and * * * * * * * change some of the water.
