Application of enzyme preparation in Freshwater Fish Feed

Excuse me, what do you think of the use of enzymes in freshwater fish? Has anyone specifically evaluated it? Hehe, it seems that we should use a little bit. I want to use it anyway. -- in use, the effect is very good: the water quality is relatively stable, basically no need to transfer water for a month, good stuff! Aquatic compound enzyme. Really, so aquatic compound enzymes are commonly used in aquatic products? Can the effect be reflected in promoting growth? Reply: what kind of enzyme? How high temperature can you bear? -- I used Xinhua Yang's aquatic compound enzyme, which has been used since 2003. At that time, it was called bacteriolytic enzyme and could withstand 90 °granulation. I don't understand the enzyme activity and so on. It's fun to have money to go to waste! The reply to the moderator of Han Pig means that no enzymes can be added to aquatic products? Is there any enzyme that is said to be resistant to 90 degrees in response to k54108? Fungus enzyme is too vague.-- recently, some enterprises have been talking about high temperature resistant aquatic phytase products. I wonder if anyone has used them?
