Abstract
The application discloses application of Prunella vulgaris extract in prevention and treatment of fish parasitic disease infection. Inclined tube worm in-vitro soaking experiments show that the insecticidal effect of Prunella vulgaris extract and zinc sulfate is equivalent after 48 hours, and the mortality rate is above 95.44%; based on the growth condition of rainbow trout feeding on Prunella vulgaris extract, the specific growth rate of fish is significantly improved, the growth performance is improved, and the growth of fish is promoted; the plasma biochemical indexes after parasitic infection show that the addition of 0.25% to 1% Prunella vulgaris extract in feed can significantly reduce stress caused by pathogenic stress and protect the health of fish liver.
