| Summary: | Anaesthesia is a widely used tool in fish handling, sampling and surgery in aquaculture;
thus, fish anaesthesiology has been studied for a long time. In this case,
there are several common anaesthetics in aquaculture, namely tricaine methanesulfonate
(a chemical agent) and clove oil (a natural agent). Recently, there was
an increasing interest to use herbal materials (other than clove oil) in fish anaesthesia.
In this review, current knowledge about the use of herbal anaesthetics has
been summarized. To date, essential oils/extracts of different plants have been
studied for fish anaesthesia; most of them belong to Lamiaceae, Verbenaceae, Lauraceae
and Myrtaceae. In addition, menthol, linalool, myrcene, cineole, globulol,
spathulenol, guaiol, caryophyllene oxide, terpinen-4-ol and dehydrofukinone are
herbal compounds that their anaesthetic effects have been studied in fish. Compared
with clove oil and eugenol as the most common herbal anaesthetic, all
tested herbal materials are less efficacious to anaesthetize fish. Some plants’ essential
oil/extract, namely Aloysia triphylla, Myrcia sylvatica, Lippia alba and Curcuma
longa, have beneficial health effects including suppression of physiological
and oxidative stress. There is a lack of data in mechanism of anaesthesia and
health effects of the herbal anaesthetics, which should be followed in future studies.
In addition, most of the current studies have focused on certain fish species
such as silver catfish (Rhamdia quelen), tambaqui (Colossoma macropomum) and
common carp (Cyprinus carpio), and in most of the studies, essential oils/extracts
of South American plants have been used. Thus, there is a need to study other fish
and plant species. |
