What precautions should be taken when processing snake venom? A full breakdown of the key operational points
1. Pay attention to safety when extracting and processing snake venom. To strictly prevent venomous snakes from injuring people, the movements for releasing the snake during and after venom extraction must be quick. When returning a snake that has been milked to its cage, first place the snake's body inside, and when the snake's head approaches the edge of the container opening, let go quickly. If you cannot withdraw your hand in time when releasing the snake, you can easily be bitten by the snake striking back. 2. Venom extraction equipment must be strictly sterilized. 3. If the venomous snake clamps onto the vessel and will not let go, you may gently swing the snake's trunk; if it still will not release its bite, you may gently twist its neck, or use a small stick or your finger to stimulate the snake's cloaca.

Processing operation key points and quality control methods for mackerel and Spanish mackerel
Mackerel and Spanish mackerel are rich in nutritional value, with DHA and EPA content second only to tuna, and can enhance the body's immunity. They are also very low in price and are well received by consumers at home and abroad. However, mackerel and Spanish mackerel contain a relatively high amount of histidine. When the fish is not fresh or has spoiled, after the action of decarboxylase produced by bacteria, histidine is decarboxylated to produce histamine. When histamine accumulates to a certain amount, there is a risk of poisoning after human consumption. Therefore, process conditions must be strictly controlled during processing to ensure product quality. 1. Processing operation key points

What are the specific operation methods for broodstock rearing ponds?
The daily operations of the managers in the rearing pond directly affect the feeding of the broodstock and the success or failure of the rearing. Because the large yellow croaker is very timid and easily startled, the sounds made by managers walking around in the rearing room, feeding, handling tools, and so on, as well as the sudden change in lighting caused by opening the door, may cause the large yellow croaker to temporarily stop feeding or feed less, and may cause it to swim wildly and dash about, so that it hits the pond wall or jumps out of the pond, causing injury or death and affecting the normal development of the broodstock's gonads.

Correct Methods and Operating Procedures for Venom Collection from Snakes
There are two methods for collecting snake venom: "dead collection" and "live collection." "Dead collection" is a special *destructive method in which the venom glands are excised from the head of a venomous snake cut off by a processing facility, or from rear-fanged venomous snakes and sea snakes with low venom yield after they have been anesthetized and killed; it is used only occasionally under special circumstances. Generally, the "live collection" method is used so as to make full use of snake resources. Several "live collection" methods are briefly introduced below. (1) Electrical stimulation venom collection method: This method uses a weak electrical stimulation device such as a "needle anesthesia instrument," with a specially made electrode to stimulate the inner wall of the snake's mouth.

Key Points and Detailed Operation Methods of Lily Whitening Processing Technology
Lily is one of the important health vegetables. The traditional processing method is to blanch the harvested lily and then dry it in the sun. Lily dried by this method still has a relatively high moisture content, is not resistant to storage, and is prone to discoloration. In the past, people used sulfur fumigation to maintain the whiteness of lily, but lily processed by this method is harmful to people's health. Now the dehydration method is used to dry lily, the moisture content is low, and after color protection, blanching and dehydration, discoloration is not likely to occur, which better solves the quality and safety problem of lily caused by sulfur fumigation.

Detailed Explanation of Lily Propagation Techniques: Common Methods and Key Operation Points
Mainly propagated by scales, bulbs and bulbils. I. Cultivating seed bulbs (1) Scale propagation When lily leaves begin to turn yellow in autumn, select robust disease-free plants, dig up the bulbs, cut off the base to separate the scales, take the inner-layer scales, and from September to October on prepared beds, open furrows and plant them at a plant spacing of 3 cm and a row spacing of 17 cm, cover with 3 cm of soil, and cover with grass to preserve moisture. After planting, small bulbs grow from the cut surface, develop into new plants in the spring of the 2nd year, and in autumn are either transplanted for final planting or continuously cultivated for 3 years; the large ones are dug up for
