"All garlic products significantly reduced parasite mean survival time
in vitro, from 13 h to <1 h. In fully randomised trials, the number of parasites was also significantly reduced on infected fish exposed to garlic from different sources. Two garlic treatments (minced and granule forms) reduced worm burdens by 66% and 75% after three doses, whereas Chinese freeze-dried garlic and allyl disulphide were 95% effective after a single application. In fact, Chinese freeze dried garlic was equally effective as Levamisole, a licensed livestock dewormer that is highly effective against
G. turnbulli but not routinely prescribed for use in fish; hence, garlic may be a potential alternative treatment for gyrodactylosis."

"During this 13-week study period, Sand tiger A increased the frequency of feeding days
and increased the amount of food per feeding when offered garlic-injected food. Sand tiger B
also increased the amount of food consumed on certain individual days but overall decreased its
food intake. Since the cessation of the garlic additions, Sand tiger A has continued to consume
its targeted food amount during most weeks. Sand tiger B has continued to eat sporadically."

"The results indicate that the inclusion of 1.3% garlic in the diet of orange-spotted grouper enhances feed efficiency, fish growth and resistance to infection by
