Comprehensive Prevention and Control Techniques for Soft-Shelled Turtle Gill Gland Inflammation
Since the intensification of soft-shelled turtle farming, because research on turtle diseases has lagged behind production, various hidden disease risks have remained latent. Among them, the most harmful and also the most difficult to treat, turtle gill gland inflammation, has gradually become prevalent in recent years. At the farm where the author works, the annual losses caused by this disease account for about 50% of total losses. This disease repeatedly occurs in broodstock turtles and adult turtles, and has now developed to affect the entire production process. 1 Main symptoms and pathogens This disease is mainly characterized by systemic edema and pale plastron. Most have intact body surfaces

How to comprehensively utilize fish processing by-products
The fish heads, fish tails, minced meat, scales, skin, viscera, bones, gallbladders, etc. left over from fish processing contain large amounts of protein, amino acids, trace elements and vitamins. Using these protein resources, various deeply processed products can be made, including soluble edible fish protein powder, liquid fish protein feed, fish scale glue, fish skin glue, bone paste, fish protein calcium candy, bile pigment calcium salt and bile acid salt, etc. Comprehensive utilization of fish processing by-products can reduce the cost of main products and increase the added value of aquatic products; it can also protect the environment and reduce wastewater and waste emissions, achieving relatively high economic, ecological and social benefits.

How to prevent and treat swine influenza? A comprehensive guide to integrated prevention and control techniques
Swine influenza is an acute, highly contagious infectious disease caused by the synergistic action of swine influenza A virus and Haemophilus suis. It occurs in pigs of different ages, sexes and breeds. Once the disease breaks out, it rapidly spreads throughout the whole herd. Symptoms include high fever, coughing and difficulty breathing. Most affected pigs show a benign course, but death can occur when complications are present. I. Causes: Abrupt climate changes with sudden cold and heat mean the protective qi cannot defend the exterior; pathogenic wind-cold and wind-heat invade the skin and muscles, then pass to the lungs, causing this disease. Affected pigs suddenly

What is licorice lemon? A comprehensive guide in one article
This product belongs to the category of preserved fruits (liangguo), and is made by further processing salted lemon embryos. Its processing technique is as follows: 1. Raw material handling: the salted lemon embryos need to be soaked in water to remove part of the salt, using a large amount of clean water for soaking. Before the lemon salted embryos are processed with table salt, if the raw material is large, it can be sliced, generally crosswise slices are preferred; if small, it can be salted whole. Because when processing licorice lemon the raw material may be sliced or salted whole, the dehydration time for sliced raw material can be shortened, while the desalting time for whole ones will be relatively longer. The degree of desalting generally requires leaving at least 2% salt

Detailed Explanation of Key Points of Comprehensive Garlic Management Technology
In garlic production management, early-stage management is relatively simple, as the plants rely on the nutrients stored in the seed garlic for growth. When they grow to 5-7 leaves before winter, they only need to survive the winter safely. After spring begins, as temperatures rise, garlic roots undergo their second major root flush. After the mother bulb recedes, the plants immediately enter vigorous growth, and it is during this period that garlic yield is formed; at the same time, this period is also a time of high incidence of pests and diseases. Therefore, spring management of garlic should be strengthened to lay a good foundation for a high garlic yield. 1. Management during the greening stage After "Jingzhe," as

What are the comprehensive pest control methods for licorice?
The leaf beetle (Apophylia flavovirens) is a leaf-eating pest of the subfamily Galerucinae in the family Chrysomelidae. It causes very serious damage to licorice and is one of the main obstacles to developing licorice production. This insect is distributed to varying degrees in **, the Hexi region of Gansu Province, and the licorice-producing areas of Liaoning Province. It mainly damages sweet licorice (Glycyrrhiza glabra) and does not harm other tree, shrub, or grass plants. Throughout the entire growing season, adult insects cause the primary damage and have a large feeding capacity; adults and larvae often overlap in causing damage. Control methods: Experiments have shown that dichlorvos emulsion

Comprehensive Utilization Methods of Fish Fingerling Ponds During the Winter Fallow Period
Raising market-size fish: Using winter-fallow fingerling ponds to raise one season of market-size fish can both increase production and help ease the "summer shortage" in the aquatic product market. Because the rearing period is relatively short and temperatures are relatively low, the following techniques should be adopted: 1. Stock early, that is, stock immediately after the fingerlings are combined into ponds, so as to make full use of the growing period. Stocking rate is calculated at a maximum water depth of 2 m, generally 125-150 kg per mu. The stocking ratio is generally about 40% silver carp, about 10% bighead carp, about 30% grass carp and bream, and about 20% black carp and common carp.
