Don't forget to protect the parent fish in order to induce labor.
Reducing the death of spawning parent fish is an important technical work for fish fry producers. In the production practice, we found that there are two reasons for the death of parent fish: first, the physical exertion of parent fish in the process of spawning and reproduction, coupled with the side effects of spawning drugs, reduce the resistance of parent fish, if the fish is seriously injured, a variety of pathogens will take advantage of the opportunity to infect the fish and cause disease, resulting in the death of the parent fish. Second, the physique of the parent fish is poor, the gonadal development is poor, or the water temperature changes greatly during the induction of labor, and the dosage of drugs used to induce labor is inappropriate.

Processing technology of large silverfish (2)
Second, the processing of light dry products of large silverfish is simple and convenient for storage, and this processing is more popular among consumers than dried salt products because it can preserve the inherent flavor of silverfish. 1. Processing process raw material → cleaning → alum water soaking → secondary drying → stacking cooling → packaging → preservation 2. Main points of operation (1) Raw material treatment: first, remove miscellaneous fish, shrimp and other impurities, pour the silverfish into a wooden bucket filled with half a bucket of water in advance, and add food.

Matters needing attention in fishery production during heavy snow
The process of rain and snow since January 10 has affected 77.862 million people in 14 provinces (autonomous regions and cities), including Anhui, Jiangxi, Henan, and Hunan, and 28 people have died as a result of the disaster. Ningbo also began to snow heavily from 4:00 this morning, and the snow thickness reached 2.5cm. In the face of the worst snow in the country in 50 years, fishery production in Yinzhou District should pay attention to the following points: 1. Deepen the water level of the pond as far as possible. Prevent fish frostbite due to low water level. Because when the water level in the pond drops too much,

What should be paid attention to when releasing fish fry in winter in the reservoir
Every winter is the golden season for releasing silver carp, bighead carp, grass carp and herring to the reservoir. However, many mariculturists report that a large number of dead fish and swimming diseased fish will be found on the water surface of the reservoir within 2 ~ 7 days. The skin of these fish loses luster and the body surface mucus increases. According to the above symptoms, it can be inferred that the fish is suffering from a typical "incompatibility of soil and water". The disease is mainly caused by the sharp change of water temperature and the strong stimulation of nerve endings in the skin of fish, which leads to the dysfunction of internal organs and its death.

Common diseases of parent fish and their prevention and treatment
1. The pathogen of vibrio is Vibrio alginolyticus. When the fish is sick, it is slow to move, often swims out of the water, and the food intake is reduced or not eaten; the ends of the caudal, ventral and dorsal fins are congested and inflamed, and the tissue between the fins spreads gradually, and when the fin fester is severe, the festering focus of the body surface of the diseased fish is uncertain, and in serious cases, it rotates into a deep hole, the bones are exposed, and Vibrio can be isolated from blood and internal organs, resulting in a high mortality rate. Prevention and treatment: ① uses vaccine to immunize fish. Soak in ② drugs, usually with 100ppm

To identify fish species by observing their faces and colors.
A look at the specifications of fish species the specifications of the same kind of fish in the same pond should be neat and uniform, with little difference in body length and weight. On the contrary, the overall survival rate of poor fish species with large individual gap and uneven quality is often very low due to predation, mixed germplasm, poor feeding and other reasons. Second, look at the body color of fish species. The body color of fish species is bright and full of luster. Generally speaking, the back of high-quality silver carp should be silver-gray, the side of the body and abdomen should be silver-white, and the body color of high-quality grass carp should be light golden yellow and gray-black net.

Treatment of fish bleeding
The factors that cause goldfish bleeding are more complex, generally caused by viral, bacterial and environmental factors: 1. Viruses, bacteria (generally believed to be caused by single cell bacilli) and parasites invade the fish body, causing fish body or local damage. 2. Water quality relationship whether using tap water fish, or lake water or well water fish, after standing or exposure for 2 - 3 days, can be used. If used without treatment, the light will make the fin scales congested, and the heavy will make the goldfish die. [Symptoms]

General principles for raising antler deer
The main results are as follows: (1) in order to improve the production performance of deer, the feed should be matched scientifically and reasonably according to the local feed source, species, reserve, feed quality and management conditions of deer, so as to meet the needs of antler deer for nutrients. Antler deer have different nutritional needs in different periods. For example, male deer need more nutrition during mating period and antler growing period than female deer, while female deer need more nutrition during pregnancy and lactation. For this reason, in the process of feeding, the feed supply plan should be made in advance to ensure timely, scientific and cooperative.
