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 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

Detailed Explanation of Small Cage Culture Techniques for Tilapia
Small cage culture refers to high-density fish farming in small cages with a volume of 1-4 cubic meters. Because tilapia tolerates low dissolved oxygen and has strong disease resistance, it is relatively suitable for high-density cage culture. 1. Selection of culture conditions: Choose small cages in sheltered and sunny spots with broad water surface, stable water surface, no strong winds and waves, and a year-round water depth maintained above 5 m, with clear and pollution-free water quality, in reservoir branches, branch canals and other places; it is best to have a certain amount of slight flowing water, and the water flow speed is preferably 3-10 m per minute.
