Abstract
Anaesthetics are important in fish culture to reduce handling stress and mortality. Eugenol is a promising anaesthetic because of its low cost, efficacy, safety margin for fish and lack of toxicity to humans. The goal of this study was to establish a protocol using eugenol as a fish anaesthetic for tambaqui Colossoma macropomum (Cuvier), and provide information for regulating authorities on establishing safety dosage protocols for its use. Juvenile and sub‐adult tambaqui were first individually exposed to doses of 35, 50, 65, 85, 100 or 135 mg L−1 eugenol for 10 min. A second experiment examined the effect of the duration of exposure to eugenol on the time required for recovery and survival of tambaqui. A eugenol dose of 65 mg L−1 was adequate to induce fish of both sizes into a surgical anaesthetic state, and recovery time was similar for dosages up to 100 mg L−1. Exposure to the ideal dose (65 mg L−1) for up to 30 min did not cause fish mortality. Fish blood glucose values were similar for all the tested eugenol doses as well as with the benzocaine control. The results show that eugenol is an efficient and safe anaesthetic for tambaqui.

A eugenol dose of 65 mg L−1 was adequate to induce fish of both sizes into a surgical anaesthetic state, and recovery time was similar for dosages up to 100 mg L−1. Exposure to the ideal dose (65 mg L−1) for up to 30 min did not cause fish mortality. Fish blood glucose values were similar for all the tested eugenol doses as well as with the benzocaine control. The results show that eugenol is an efficient and safe anaesthetic for tambaqui.</abstract><subject lang="en"><genre>keywords</genre><topic>Colossoma macropomum</topic><topic>eugenol</topic><topic>anaesthetic</topic><topic>handling stress</topic></subject><relatedItem type="host"><titleInfo><title>Aquaculture Research</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">1355-557X</identifier><identifier type="eISSN">1365-2109</identifier><identifier type="DOI">10.1111/(ISSN)1365-2109</identifier><identifier type="PublisherID">ARE</identifier><part><date>2005</date><detail type="volume"><caption>vol.</caption><number>36</number></detail><detail type="issue"><caption>no.</caption><number>11</number></detail><extent unit="pages"><start>1056</start><end>1061</end><total>6</total></extent></part></relatedItem><identifier type="istex">0D84A8E5841369F81C2AD2E0856F228377C5DF78</identifier><identifier type="DOI">10.1111/j.1365-2109.2005.01319.x</identifier><identifier type="ArticleID">ARE1319</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Science Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
