Description

technical field

[0001] The invention relates to the technical field of aquaculture feed, in particular to a low-salinity cultured Penaeus vannamei additive premix. Background technique

[0002] Vannamei shrimp (Litopenaeus vannamei), commonly known as Penaeus vannamei, is a euryhaline crustacean native to the Americas. This species has quickly become a popular aquaculture industry due to its large output, high meat yield, easy intensive farming, and delicious meat. Its output has been ranking first in the world's shrimp output for nearly ten years. In view of its eurosalinity (0.5--4.0), Penaeus vannamei not only spreads all over the seawater areas of coastal provinces, but even has a certain freshwater aquaculture market in the interior. Statistics in 2003 showed that the output of Penaeus vannamei in low-salinity (0--5) culture (that is, freshwater culture) in my country accounted for about 50% of the total. Although much has been done on Penaeus vannamei in mariculture ...
