Problems solved by technology

[0003] Traditional grass carp farming is mainly based on green feed, which takes a long time to breed and high cost; the nutrient composition of the feed is single, which cannot fully meet the growth needs of grass carp, and is not conducive to the output of grass carp and the meat quality of grass carp

Some existing grass carp feeds still have problems such as excessive addition of hormone drugs and high content of heavy metals, which make grass carp prone to various diseases
