Monogenean infections in aquaculture are responsible for significant economic losses.
Ginger and garlic are the well-known herb which possess anti-parasitical properties.
The current study focuses on the in vitro treatment with ginger and garlic extractions
towards the behavioural changes of Cichlidogyrus sp. at various concentrations and
also their effectiveness. In vitro trials revealed the clear anti-parasitic effects of herbs.
Herbal extracts, prepared from oven-dried herbs, were tested. After specific time of
exposure, the behavioural changes of monogeneans were recorded, which involved:
Straight and Elongated; Irregular and Elongated; Straight and Shortened; and Coiled
and Shortened. Besides, increased extract concentration was associated with reduced
time to parasite cessation, with garlic extract being more efficient; at 100 and 400
ppm ginger and garlic extracts, monogeneans died at 75.1±0.6 and 36.3±0.2 min;
31.0±0.3 and 5.2±0.1 min, respectively. These findings show that immersion in herbal
extract provide an effective result for monogenean in vitro treatment.
