Cage Culture Methods and Technical Key Points for Sturgeon
The sturgeon series varieties have the characteristics of wide adaptability, fast growth, short culture cycle, good market prospects and high economic returns. Using cages to culture sturgeon is a very good intensive production method. Compared with pond culture of sturgeon, it has the following advantages: large water exchange volume

Key Technical Points for Fingerling Rearing in Carp Farming
Summer fry fingerlings must be selected from those that are disease-free and uninjured, robust in constitution, lively in movement, and uniform in size. Fingerling rearing generally adopts mixed culture of 2 to 3 species of fish, but with one species as the main one. In a pond with carp as the main cultured fish, stock 6,000 to 8,000 summer fry per 667 sq m, combined

Key Technical Points for Feeding and Management of Nutria During Lactation
The focus of feeding and management during lactation is to ensure normal milk secretion in the female nutria and normal growth and development of the young, and to improve the survival rate of the young. (1) To promote milk production in the female nutria, manual plucking of the mammary hair and the use of Chinese herbal galactagogues can be adopted to promote mammary gland milk secretion. Manual

Key Technical Points for Safe Overwintering in Velvet Deer Farming
Cold protection and insulation. When the outside temperature is 15°C, a portion of the nutrients taken in from feed must be diverted to resist the cold in order to maintain normal body temperature. At this time, in northern regions, 1 to 2 layers of bundled corn stalks should be set up outside the deer shed walls to block wind and cold.

Key Technical Points for Summer Rearing and Management of Angora Rabbits
I. Cooling and Heat Prevention (1) Shade and Ventilation The rabbit house must not allow direct sunlight to fall on the rabbit cages; a shade awning should be built, and the doors and windows of the rabbit house should be wide, with skylights, ventilation windows or exhaust fans installed to keep the air circulating inside the rabbit house. Attention should be paid to lighting, ventilation and moisture prevention. (2) Reducing feed

Key Technical Points for Winter Feeding and Management of Beef Cattle
In winter, cattle are in a state of consuming feed, and both feed utilization rate and market-ready rate are very low, thus forming a vicious cycle of "full in summer, fat in autumn, thin in winter, weak in autumn." After a winter, cattle can lose up to 25%-30% of their body condition. To solve this problem, the following technical measures should be taken.

Key Technical Points for Rapid Rearing and Management of Free-Range Chickens
1. The chicken coop can be built by renovating an old house, or a new coop can be built separately. Inside the chick coop, install elastic plastic netting or bamboo woven netting, with a mesh diameter of 1 cm and the net about 100 cm above the ground. If an old house is renovated, light windows and ground windows should be opened at the front and back. The light window is 150 cm above the ground, and the ground

Loach Farming Methods and Technical Key Points in Wooden Boxes
Where there is a water source but it is not suitable to build a pond, loach can be farmed in wooden boxes, and they can be harvested after half a year of rearing, with each box producing 15-20 kg of loach. 1. Wooden box construction. Specifications 1 m x 1 m x 1.5 m, with a spatial capacity of 1.5 m3. Install a water inlet and outlet with a diameter of 3-4 cm on one or both sides

Prevention and Control Methods and Technical Key Points for Rotting Stomach Disease in Sea Cucumber Aquaculture
This disease mostly occurs in the late auricularia larval stage, and is more likely to break out during the high-temperature period from June to July each year and when larval rearing density is high. The disease has been found in both Shandong and Liaoning provinces, and its incidence rate has shown a trend of increasing year by year. The main symptoms of disease and death are: the larval stomach wall thickens

Prevention and Control Methods and Technical Key Points for the "Huaban" Disease in Sea Cucumber Aquaculture
This disease is also called "sliding board disease", "board-shedding disease" and "disintegration disease". It mostly occurs when barrel-shaped larvae metamorphose into five-tentacle larvae and in juvenile sea cucumbers after the larvae attach to boards. It is one of the most serious and commonly occurring epidemic diseases in the late stage of sea cucumber (Apostichopus japonicus) seedling rearing. The disease is highly contagious and develops quickly
