Lizardfish artificial breeding technology

Habits: Dorsaurus lives in the cool waters of the mountain rivers and rivers, and dwells in stone holes. Active food is often found at night. It usually hides in rock holes during the day. The food is mainly aquatic insects, fish and shrimp, crabs, frogs, etc. (Other animal meats also eat). When the baby salamander is young, it has three pairs of branching nephew on both sides of its head and neck. It is the respiratory organ that lived in its early waters. About 3 years or so, the young worms disappeared on their own, and their respiratory organs were replaced by the lungs. With the change and influence of geographical conditions, these animals are currently only preserved in three species of the family Conservancy. In addition to the distribution of the United States and eastern Japan, the main producing areas are China, and there are seventeen provinces and regions in the country, especially the mountains and rivers in the middle and upper reaches of the Yangtze River, the Yellow River, and the Pearl River. For a long time, due to the inefficient protection of natural resources and the large amount of artificial capture, the giant salamander, a unique aquatic resource in China, has been severely degraded, and some producing areas have almost disappeared in recent years.

Artificial rearing: A batch of fertile baby fish with reproductive ability is introduced into the artificial ecological simulation pool for breeding from the wild. The rearing pond is based on the characteristics of the hirunus and the dark and habitat holes. Artificial rearing ponds are built in dark arched rooms, each pool is 4 to 5 square meters, the pool is 1 meter deep, and 2.5 to 5 kilograms of fish are put on 4 to 5 tails. The water source for the rearing pond is a natural stream, and the water temperature variation is maintained in the range of 10-22°C throughout the year. The daily management of artificial rearing giant salamanders focuses on the administration of esophageal water and feeding of crabs, clams, fish and shrimp, and animal meat. As long as the baby fish eats normally, growth and development will receive good results. In addition to adequate patronage, pool water management is also important. If the pool is overfilled, the baby salamander will evade itself; if the water quality is not good and the environment deteriorates, it will cause injury and death. Therefore, the artificial feeding should always pay attention to the water quality and water temperature, and update the water in the pond so that the baby has a good water environment. This is a problem that cannot be ignored. Artificial Propagation: For sexually mature male and female broodstock, artificial breeding of baby doll fry can be obtained by hormones (human chorionic gonadotropin and luteinizing hormone) aphrodisiac and artificial insemination. The baby fish eggs are rosary ribbons. Large particles (oocyte diameter of 1.7 to 1.8 cm), embryo development changes slowly, fertilized eggs from the beginning to the emergence of 35-40 days, so incubation management has brought a lot of difficulties, the incubation of fertilized eggs is the use of still water incubation method, The water quality of hatchery water should be fresh, and the water temperature should be relatively stable. It is advisable to use 18-20C, and exchange the hatching water 4 to 5 times within 24 hours. The number of water changes can be flexibly controlled based on water quality and water temperature. If the water temperature does not change much, the fertilized egg can emerge after more than 30 days of incubation. After the hatched seedlings are opened for food, they can be cultivated in the pond. Seedlings cultivation pond should not be large, l ~ 2 square meters is appropriate, pool depth 60-80 cm, each pond about 10 fish fry, feeding and management methods and adults are similar, but the feeding of food in the amount and quantity to be suitable Larval appetite. Each dose should not be much, feeding materials to facilitate larval intake intake. The cultivation of baby fish fry is a highly technical work. The management must be careful and must not be neglected.

The routine postpartum administration of oxytoxin or antibiotics is unnecessary. But if the animals got postpartum problems,  we recommend these postpartum care medicines: Oxytocin Injection, Cloprostenol Sodium Injection, Estradiol Benzoate Injection. All the veterinary medicines are GMP certified and has wide market and good reputation in China. we are now engaging in open overseas market with our high quality and enonomic price veterinary medicines.
