What are the basic contents of pond management in fish farming?
1 Visit the pond regularly to observe the dynamics of the pond. Every morning, evening and midnight, we will continue to inspect the ponds three times to observe fish activity, feed intake, water quality changes, weather conditions, etc. We will do a good job in feeding and measuring water temperature and water quality to determine if there are abnormal fish or fish. Diseases occur, prevention work is done well, and flood prevention pools are prevented and controlled. 2 According to the weather, water temperature, season, water quality, fish growth and feeding conditions, determine the type and amount of feeding, fertilization. 3 Grasp the pool of water, pay attention to regulate the water quality, maintain the appropriate amount of water, and fight drought. 4 At any time to remove pool side weeds and pool surface dirt, keep the ponds clean, and find that dead fish should be removed and buried in time to prevent the occurrence and spread of fish diseases. 5 Reasonable use of fishery machinery, good maintenance and safe use of electricity. 6 Do a good job in safety production to prevent accidents. 7 Make daily records and statistical analysis work.
Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.

for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
