Abstract
Various chemical substances are used as anesthetic agents in fish farms and research centers. The aim of this study was evaluation of sedation and anesthesia effects of Dianthus (Syzygium aromaticum), Valerian (Valeriana officinalis) and Lavender (lavandula officinalis) plants on Astronatus ocellatus fish by immersion technique. For this purpose, ?? fish with an average size of ?±?.? centimeters were selected and divided in three groups. Dianthus at a ?.? g/l, Valerian at a ?.? ml/l and Lavender at a ?.? ml/l concentration were used. Anesthesia onset, duration and recovery time were recorded separately for each group. Valerian extract was not anesthetized fish and only occasioned their sedation. Dianthus and lavender caused anesthesia that anesthesia times in dianthus was shorter than lavender. But only anesthesia duration time with lavander in comparison with dianthus was significantly (P
