Problems in the application of rapeseed meal in aquatic feed
Currently, the prices of protein raw materials are very unstable. Fishmeal has risen sharply, soybean meal remains high, and the price of cottonseed meal fluctuates greatly. Only rapeseed meal, which maintains relatively good cost-effectiveness, is gradually gaining attention. I really hope everyone can share their experience with using rapeseed meal in aquatic feed for different species. Begging you! Thank you!

In fish feed I use 15%.
--------------------------------------
As long as quality control is good, use it boldly, no problem
--------------------------------------
I say, Young Master Yin, what is the difference between what you said and saying nothing? Doing academics requires rigor!
--------------------------------------
Hehe, rapeseed meal in freshwater fish feed is indeed the most cost-effective. As for the usage amount, of course it varies by fish. It can be classified according to ecological habits!
--------------------------------------
Why are the answers from the experts all so slippery? Could there be hidden rules in this too?
--------------------------------------
For cyprinid fish, we use within 25% and the effect is still not bad
--------------------------------------
Following along to learn................

The glucosinolates in rapeseed meal do not cause significant impact on the liver of grass carp when the rapeseed meal addition does not exceed 40%. What about research on other fish species? Everyone share!

In Tongwei's general mixed culture feed, rapeseed meal is 20, rapeseed cake is 10

Xiao Hei, the discussion is not active enough!

Rapeseed meal is a good thing. The usage amount varies according to fish species and stage. Note that the ratio with cottonseed meal also varies greatly depending on fish species and stage. As for the discussion of maximum usage amount, it is basically meaningless. What we make is compound feed. The first principle is the diversification of raw materials, allowing amino acids in raw materials to complement each other and achieve the best balance. We also need to consider the profit of feed manufacturers.
