Anesthetic activity of Brazilian native plants in silver catfish (Rhamdia quelen)

Abstract: There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture and handling. In this context, the present study evaluated the potential of essential oils (EO) of three Brazilian native plants (Hesperozygis ringens, Lippia sidoides and Ocotea acutifolia) as anesthetics for the silver catfish - Rhamdia quelen. Moreover, an analysis was made of the chemical composition of these oils and their influence on stress parameter. EO of H. ringens … Show more

“…Thus, for these reasons, there is a growing demand for low-cost anaesthetic products that are easy to obtain and offer security to the animals, to the handlers and to the environment. Some essential oils (EO) derived from plants have been shown to be a viable alternative to reduce stress during fish capture and handling (Silva et al, 2013). Different oils have been used to anaesthetize fish, such as Eugenia caryophyllata (Weber et al, 2009;Pawar et al, 2011), Cinnamomum camphora, Mentha arvensis (Pedrazzani and Ostrensky, 2014), Melaleuca alternifolia (Hajek, 2011), Ocimum gratissimum (Benovit et al, 2012), Hesperozygis ringens and Ocotea acutifolia (Silva et al, 2013).…”

“…Recovery of H. geographicus within 30min was not obtained after anesthesia with 200µL L -1 EOLO. Silver catfish anesthetized with EO of L. sidoides also did not recover normal behavior within 30min at most concentrations tested, and this EO causes mucous loss and mortality (SILVA et al, 2013). These side effects of EOLO were not observed in H. geographicus, probably because the percentage of carvacrol was lower (41.7%) in EOLO.…”

“…There are no studies of anesthesia with EOLO, but the EO of the carvacrol chemotype of Lippia sidoides, which contains 68% carvacrol, the main compound of EOLO, can anesthetize silver catfish (SILVA et al, 2013). Recovery of H. geographicus within 30min was not obtained after anesthesia with 200µL L -1 EOLO.…”
