Matters needing attention in mackerel culture

Channel catfish is also called channel catfish, which belongs to the genus channel catfish, and some people also call it long kiss. At present, the main producing areas of mackerel in China are Liaoning, Huaihe River and the Yangtze River. The meat of mackerel is delicate and tender and rich in protein, so it is a precious nourishing aquatic product. In order that the mackerel can appear on the table of more people, and the artificial culture technology of the mackerel has also made great progress, what problems should be paid attention to when raising the mackerel? Let's follow the editor to take a look at the matters needing attention in its breeding.

1. Cleaning of fish ponds

The cleaning of fish ponds is very important, because many farmers do not pay attention to the cleaning of fish ponds, resulting in a large area of fish floating after the release of fish fry. When we breed the mackerel, about 10 to 15 days before the fry is put in, we should remove the silt from the fish pond and then disinfect it with quicklime or microbial preparation base modification products. After at least seven days of drying in the pond, fresh water is injected to wait for the release of fish fry.

2. Fish fry release

The breeding of mackerel should be purchased through regular ways, and the fry should be disinfected before rearing, followed by only about 1000 fish per mu. In order to regulate the water quality and make the channel catfish survive better, it is best to use multi-species fish fry for mixed culture. Silver carp, mandarin fish, sea bass, etc., are generally used. Do not put predatory fish such as carp and grass carp, so as not to cause unnecessary harm to the carp.

3. Water quality regulation

Mackerel has high requirements for water quality, and when it is convenient to change water, it is best to change water frequently. 2/3 of the water is changed every time, and we also need to retain some of the old water, mainly because there is proper plankton in the fish ponds for the fish to hunt. Secondly, without changing the water, we can put oxygen enhancers and other microbial products to improve the water quality to regulate the water quality. the effect is also very good, but the cost will be higher than the change of water.

4. Daily management

Ruiguan management is also one of the items that we need to pay special attention to in the culture of mackerel. It mainly includes cleaning and disinfection of fish ponds, anti-escape, cleaning up food residues and recording the daily food intake and exercise of fish, etc., according to these timely processing. The cleaning and disinfection of fish ponds are usually carried out every half a month, and the food residue can be cleaned up about an hour after each feeding.

5. Standardize the use of drugs

Many farmers are very irregular in the use of drugs when they breed mackerel. When it is found that the fish is abnormal, the medicine is used casually without a diagnosis, which leads to other diseases and leads to an irreparable situation. In addition, in the usual feeding, in order to enhance the resistance of the mackerel, the dosage of antibiotics added to the feed will be non-standard, leading to adverse reactions and even death. Therefore, we need to have special fish culture and disease prevention technology, so that we can make a correct treatment.
