Symptoms and Control Methods of External Parasites in Turtles
Cause: Aquatic turtles and terrestrial turtles become infected because parasites are present in their wild living environment. The types of parasites include ticks, mites, fleas, leeches, and others. Symptoms: Parasites are visible on the surface of the turtle, and the turtle becomes emaciated. Control methods: Once parasites are found on the turtle's body surface, remove them immediately. For newly purchased turtles, soak and wash them in a 1% trichlorfon solution for 2 consecutive days. The incidence rate is relatively low in captive-bred turtles. For aquatic turtles, soak and wash them in a 0.7 mg/L copper sulfate solution for 20-30 minutes, and the leeches will drop off and die.

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

Causes and Control Methods of Eggplant Fruit Rot
"Rotten eggplant" is the collective term used by vegetable growers for gray mold, cotton blight, and sclerotinia rot. In winter and spring, eggplant fruit rot in greenhouses is mainly caused by gray mold, with sclerotinia rot as a secondary cause, and the two often occur together. The main symptoms are that the disease mainly affects small fruits and green fruits, and can also affect leaves. When fruits are affected, the residual filaments and receptacles are usually infected first, then the disease spreads to the fruit and fruit stalk, causing the peel to become grayish-white and soft-rotted. In the late stage of the disease, a large amount of grayish-white mold grows at the fruit stalk, after which the fruit loses water and becomes mummified. However, the disease conditions are mostly suitable under low temperature and high humidity
