A Brief Introduction to the Effect of Mannich Base Ingredient in Killing Fish Parasites
Mannich base ingredient is a highly efficient biological insecticide extracted from the roots and leaves of the pure plant eucalyptus and made through scientific processing. More than 1000 years ago, people already knew that eucalyptus has medicinal value. Especially in rural areas of southwest China, its roots and leaves are commonly soaked into a liquid to directly kill maggots and other pests. In recent years, after in-depth research by relevant departments at home and abroad, preparations have been extracted from it, and it is recognized as a biological insecticide that is broad-spectrum, highly efficient, low-toxicity, easily degradable, residue-free, free of "three-causing" effects, and

What kind of fish is the Nile tilapia? An introduction to its breed characteristics
The Nile tilapia (Oreochromis niloticus), or tilapia for short, is also called the Nile tilapia. It is native to Africa. Taiwan, China introduced it in 1966, and trial farming produced good results; it has now become one of the main species in Taiwan's freshwater aquaculture. In 1978, mainland China introduced this fish successively from Thailand and from the Nile river system. After years of trial farming, the results showed that the Nile tilapia can adapt to the water conditions of most regions of our country, grows well, and has a good yield-increasing effect.
