What problems should crucian carp culture pay attention to at ordinary times?

Crucian carp is widely distributed in China, and it is cultivated all over the country. Crucian carp is one of the main edible fish in China. Crucian carp has delicate meat, delicious taste, high nutritional value, rich in protein and a variety of nutritional elements, and very high medicinal value. What problems should crucian carp culture pay attention to at ordinary times?

First, pay attention to the feeding density

In general, the density of adult fish per mu in a culture pond is controlled at about 1500-1700 fish per mu, which is distinguished by the density of water depth. A little more fish can be raised a little deeper, and about 1700 fish can be raised at a depth of 2.5m. When crucian carp grow to about one jin, it will be reduced appropriately, otherwise it will lead to excessive breeding density, whether it is disease or lack of oxygen, it will occur very frequently. When you find that sawdust areas often surface, you should know that this is a high breeding density.

Pay attention to the regulation of water quality

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 one of the bad water quality. the problem of water quality also includes the content of trace elements in the water and the content of plankton, so we often encounter the addition of oxygen, the water quality is still very poor, the fish 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.

Pay attention to the problem of mixed culture

First of all, there is the problem of the proportion of mixed fish species, which is generally between 10% and 20%. Secondly, mixed fish species can not have any carnivorous nature, and should be more meek. Black fish and catfish are the two species that are more suitable, such as grass carp and carp, but the proportion of these two kinds of culture should be controlled at 10%, because this is a relatively large intake of fish species, easy to seize the food of crucian carp.

Pay attention to the size of the feed

Fish culture should pay attention to the feeding problem in time, especially in the feed size, too small will cause the feed to bloom as soon as it enters the water, it is not conducive to the young fish to eat, it is too big to eat, the feed fed in the fry period is crushed and granular, the fry of young fish will be more dense, and the feed will not be wasted in the water. When the fry grows to 20-50g in the later stage, the feed size is controlled at about 0.1cm. When the feed is 50-250g, the feed should not exceed 0.2cm250g. After that, the feed size can be controlled in 0.3cm.

The above is the introduction of some problems that need to be paid attention to in crucian carp culture by Tuliu. fish culture is a troublesome one. Because the fish are in the water for a long time, it is difficult to judge when something goes wrong, so it can only be checked by random checks occasionally. So daily management is very important.
