How are wild Schizothorax prenanti domesticated? Keep the precautions firmly in mind
Schizothorax prenanti belongs to the Cyprinidae family, Schizothoracinae subfamily, and Schizothorax genus; it is also known as Yayu, fine-scaled fish, and carp. As market demand for Schizothorax prenanti increases, its natural resources fall short of demand.

A Detailed Guide to the Methods of Capturing and Taming Wild Hazel Grouse
The history of artificial breeding of wild hazel grouse is still less than 10 years, so capturing and taming are effective ways to solve the shortage of breeding stock. 1. The trapping time is best from September to November each year. They lay eggs in May and the chicks hatch in June; during this period the hazel grouse is in plump body condition, reaching its highest weight of the year. 2. Trapping methods: set up some homemade trapping tools in areas where hazel grouse are frequently active, such as snares, capture cages, etc. If conditions permit, you can make full use of the hazel grouse's flocking tendency by continuously imitating the hazel grouse's call to make the birds gather together, and then capture them with a net. 3

What are the precautions for selecting wild eel fry
To succeed in farming yellow eels (Monopterus albus), high-quality fry is the prerequisite. Therefore, when selecting high-quality wild eel fry, the following ten points should be noted. 1. The size of the eel fry should be appropriate. Generally, the artificial farming period is 5-6 months, and the weight gain multiple is 2-4 times. At the end of the year when selling, only individuals with a size of over 100 g can fetch a higher price. Therefore, fry stocked in April-May should weigh over 30 g. 2. Try to choose cage-caught fry. Yellow eel fry come from two sources: artificial breeding and natural capture. The number of artificially bred fry

A Complete Analysis of New Techniques for Clearing Ponds and Removing Wild Fish
Currently, the commonly used pond-clearing drugs in production include quicklime, tea seed cake, bleaching powder, bleaching essence, trichloroisocyanuric acid, etc. 1. Quicklime pond clearing. Quicklime (CaO) reacts with water to form strongly alkaline calcium hydroxide, causing the pond water pH (acidity and alkalinity) to rise sharply to 11-12, thereby killing wild miscellaneous fish, harmful organisms and various pathogens. 2. Tea seed cake pond clearing. Tea seed cake is a round cake pressed from the residue left after oil extraction from the seeds of the oil tea plant. Method of use: break the tea seed cake into small pieces, soak in

How to Clear Wild Trash Fish from Fish Ponds? Four Methods to Solve It Easily
When filling, changing water, and feeding aquatic plants in intensive ponds, wild trash fish or their eggs such as sharpbelly, topmouth gudgeon, crucian carp, loach, and grass shrimp inevitably get mixed in. These wild trash fish not only have strong food-grabbing ability, a large feeding volume, and low economic value, but also reproduce quickly. In addition, carnivorous predatory fish such as snakehead and catfish can also swallow cultured fry. Therefore, various measures must be taken in aquaculture management to remove wild trash fish. 1. Kill the wild trash fish in the pond in advance. Before stocking fry, drain the pond water, let the pond bottom freeze and sun-dry for a period of time, then add 20-3
