Abstract
   The study on electroanesthesia is part of a larger project that refers to research on the genetic determinism of the growth process in some breeds of Cyprinus Carpio species. One of the problems encountered was the handling of fish specimens in optimal conditions, without inducing stress, without causing injuries and without introducing chemicals, with a sedative or narcotic effect, into the aquatic environment. This was necessary to collect blood samples, tissue and semiological material to obtain results as relevant and compliant with those of the living environment. Among the anesthesia methods without chemicals (the method of electroanesthesia, the method of hypothermia and the method with CO₂), the method of electroanesthesia was used due to its immediate efficiency and easy recovery of fish material. Thus, the present study revealed that the most efficient current to be applied to obtain the desired effect of electroanesthesia was the alternating current rectified monoalternation.
