Preliminary study of the use of "Aqui'S" as anesthetic for handling and sampling of rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta)
Etude préliminaire sur l'utilisation de "l'Aqui'S"comme anesthésique pour la manipulation et l'échantillonnage de truites arc-en-ciel (Oncorhynchus mykiss) et de truites fario (Salmo trutta)
Résumé
The kinetic of anesthesia with Aqui'S(R) was followed on rainbow trout (Oncorhynchus mykiss) of different weight (9, 25 and 200 g). Aqui'S(R) allowed fish anesthesia in a dose dependent manner and did not induce any mortality when used less than 30 min at concentrations below 60 ml/m(3). Recovery kinetic was also dependent on the Aqui'S concentrations used.
