2. Clean and disinfect the pond. Before the stocking, use a quicklime of 75 to disinfect Dianchi Lake.
3. Loach species and stingray species stocking.é³– species: Select Chinese quail species that have good varieties, no injuries, no defects, neat specifications and strong activity. Stocking density, usually 0.4-0.5?/100-120 per mu. Yellow sturgeon species: In mid-March, mu tails weighed about 4,000 tails of 10 to 20 g of stingray species. In order to purify the water quality, another mu with a specification of 250 grams/tail of maggots, oyster species 100-110 tails (carp 10%).
4. Reasonably feed the feed. Adhere to four feeding methods.鳖 鳖 鳖 鳖 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 饲料 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 The larvae are broiled and sprinkled directly on the food field (Changyu), and the daily feed is 3-6% of the body weight of Chinese sturgeon. The feeding work was done after the stingray had finished feeding. Stingrays must be artificially domesticated before they are completely fed with artificial compound feeds. The domestication process usually takes 5-7 days. In the early period, animal feeds such as fish meat and animal viscera are mainly used as supplements for compound feeds to smoothly feed their colonies. When feeding, use sound stimulation to allow it to form a conditioned reflex, and then gradually increase the proportion of use of compound feed until it is completely fed with compound feed.
5. Water quality regulation. Fresh water is required, and it is best to use microecological agents to regulate water quality.
6. Disease prevention and control. Adhering to the principle of “preventing the main thing, supplementing it with treatment, and comprehensively preventing and controllingâ€, we regularly feed disease-prevention baits on a regular basis, and disease prevention drugs are mainly based on Chinese herbal medicines and biological agents, supplemented by western medicine. Fish disease was found and treated promptly.
