Abstract

This study presents evidence of a significant improvement in survival rates with eugenol use. Survival rates with eugenol reached 97%, compared with 52% without it. In aquaculture, transport and stocking density are recognized stressors that can increase mortality rates. The effectiveness of eugenol as an anesthetic and the impact of density during the transport of Prochilodus nigricans and Piaractus brachypomus fingerlings were evaluated. Fish were transported for 5 hours, with 1 mL and 1,5 mL of eugenol applied at varying densities. The results showed survival rates exceeding 90% for P. nigricans at 150 fish per bag and 80% for P. brachypomus at up to 100 fish per bag. These findings confirm that both eugenol use and appropriate stocking density are critical for efficient fish transport.
