Introduction: Monogenean parasites are an important part of pathogenic fish parasites that cause a lot of damage to the aquaculture industry every year.
Methods: Many clinical studies have been conducted using anti-parasitic drugs such as praziquantel and mebendazole with the aim of finding a way to treat these parasites, but their use has been costly and sometimes unsuccessful. Therefore, in recent years attempts have been paid to use medicinal herbs or plants as an alternative to the synthetic anti-parasites. In this review we obtained all available data from the scientific journals and websites and analyzed them for their antagonistic and clinical efficacies towards the fish monogeneans such as Dactylogyrus, Gyrodactylus and Neobenedenia.
Results: Rosemary (Rosmarinus officinalis), garlic (Allium sativum), ginger (Zingiber officinale), ashanti pepper (Piper guineense), peppermint (Mentha piperita), tea tree (Melaleuca alternifolia), bge seeds (Semen aesculin), and bupleurum chinense roots (Bupleuri chinensis) are the most medicinal herbs and plants that have been used against monogeneans under in vitro or in vivo conditions with promising results. In most of the studies carried out, the bath method was used to treat these parasitic diseases in fish, while in aquaculture practice, oral method is a practical method and required in the industry. In addition, unfortunately, most of the studies have no information about the bioavailability of the active ingredients of the studied medicinal plants in the organs of treated fish.
Conclusion: In most of these studies, the main focus has been on the efficacy of medicinal plants on the immunological, physiological and detoxification effects of fish, while their therapeutic properties (laboratory and clinical) have received less attention. In this study, various aspects of the effectiveness of medicinal plants against parasitic monogeneans in fish will be discussed.
