What should be paid attention to in culturing crucian carp

Crucian carp is the most common species of fish in our daily life, and its culture range is not limited in our country. There are always some problems in daily culture. In fact, many problems can be avoided if we pay attention to them. Next, let's take a look at those aspects of crucian carp farming together with the pro-agricultural network.

1. Feeding density

The breeding density is known to many people and will be paid attention to, but do you know the specific subdivision? In general, the adult fish density of each mu in the breeding pond is controlled at about 1500-1700, which is distinguished by the density of water depth. If it is a little deeper, 1700 fish can be raised at a depth of 2.5m. When crucian carp grows to about one jin, it should be appropriately reduced, otherwise it will lead to excessive feeding density, whether disease or lack of oxygen will occur very frequently. When you find that sawdust areas often surface, you should know that this is a high breeding density.

2. Water quality regulation

Water quality regulation is an issue that everyone is very concerned about, but the water quality in the hearts of many farmers refers to oxygen, which is a wrong idea, because the lack of oxygen is only a kind of bad water quality. Water quality problems also include the content of trace elements and plankton in the water, so we often encounter that the water quality is still very poor when the oxygen supply is clearly added, and the fish raised is not ideal at all. In this regard, it is suggested that we plant some aquatic plants or algae in the water, which can not only increase the content of some trace elements, but also provide rich plankton for crucian carp.

3. Mixed culture

Crucian carp culture of a single species has been not ideal, until later we found the benefits of mixed culture, then crucian carp mixed culture of what problems should be paid attention to? First of all, there is the proportion of mixed fish species, which is generally between 10% and 20%. Secondly, mixed fish species can not have any carnivorous, and should be more docile, black fish, catfish is firmly can not be mixed species. More suitable, such as grass carp, carp, but the proportion of these two kinds of culture should be controlled at 10%, because this is a relatively large food intake of fish species, easy to seize the food of crucian carp.

4. Feed size

Fish culture is the early stage to pay attention to feeding problems, especially in the feed size of this piece, too small will lead to feed just into the water on the flower, not conducive to young fish to eat, too big to eat. The feed fed during the fry period is crushed and granular, the fry of young fish will be more dense, and the feed will not be wasted when scattered in the water. In the later stage, when the fry grows to 20-50 grams, the feed size should be controlled at about 0.1 cm, 50-250 grams should not exceed 0.2 cm, and after 250 grams, the feed size should be controlled at 0.3 cm.

These are some of the problems that need to be paid attention to in crucian carp culture, and fish culture has always been a troublesome one. Due to being in the water for a long time, it is difficult to judge when something goes wrong, and we can only rely on spot checks occasionally. In some obvious cases, we can also find that others can only rely on daily attention, so in fact, the above points for attention are very important.
