Efficacy of garlic (Allium sativum) extract applied as a therapeutic immersion treatment for Neobenedenia sp. management in aquaculture

| Summary: | Garlic, Allium sativum L., extract administered
as a therapeutic bath was shown to have
antiparasitic properties towards Neobenedenia
sp. (MacCallum) (Platyhelminthes: Monogenea)
infecting farmed barramundi, Lates calcarifer
(Bloch). The effect of garlic extract (active component
allicin) immersion on Neobenedenia sp.
egg development, hatching success, oncomiracidia
(larvae) longevity, infection success and juvenile
Neobenedenia survival was examined and compared
with freshwater and formalin immersion.
Garlic extract was found to significantly impede
hatching success (5% 5%) and oncomiracidia
longevity (<2 h) at allicin concentrations of
15.2 lL L
1, while eggs in the seawater control
had >95% hatching success and mean oncomiracidia
longevity of 37 3 h. At much lower allicin
concentrations (0.76 and 1.52 lL L
1), garlic
extract also significantly reduced Neobenedenia
infection success of L. calcarifer to 25% 4%
and 11% 4%, respectively, compared with
55% 7% in the seawater control. Juvenile
Neobenedenia attached to host fish proved to be
highly resistant to allicin with 96% surviving 1-h
immersion in 10 mL L
1 (15.2 lL L
1 allicin)
of garlic extract. Allicin-containing garlic extracts
show potential for development as a therapy to
manage monogenean infections in intensive
aquaculture with the greatest impact at the egg
and larval stages. |
