Common carp with an average weight of 8 &plusmn; 0.2 g were fed for one month with a diet supplemented with Lemon beebrush essential oil (0.15 and 0.3 ml) and with normal diet as controls.&nbsp;</span><span style="font-size: 11pt;">The growth performance, body composition, biochemical and hematological factors were measured on day 30. Results of the present study showed that specimens fed a diet supplemented with Lemon beebrush EO in both dosages noticeably increased final weight (p<0.05). Group of fish fed on 0.15 and 0.3 LB in the diet had the lowest level in Hb and hematocrit indices (P<0.05). Lipid content was lower in fish fed 0.15 LB supplemented diet and ash was decreased in fish fed both LB supplemented diet.</span></p> <p style="margin: 6pt 0cm; text-align: justify; line-height: 150%; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;"></p> Lemon beebrush, Carcass, Blood parameters, Common carp 1 15 http://ijaah.ir/browse.php?a_code=A-10-35-41&slc_lang=fa&sid=1 H Gholipourkanani 10031947532846001645 10031947532846001645 Yes Department of Fisheries, Faculty of Agriculture and Natural Resource, Gonbad Kavous University, Golestan, Iran F Jamali 10031947532846001646 10031947532846001646 No Department of Fisheries, Faculty of Agriculture and Natural Resource, Gonbad Kavous University, Golestan, Iran H Jafaryan H 10031947532846001647 10031947532846001647 No Department of Fisheries, Faculty of Agriculture and Natural Resource, Gonbad Kavous University, Golestan, Iran E Gholamalipour Alamdari E 10031947532846001648 10031947532846001648 No Plant Production Department, College of Agriculture Science and Natural Resources, Gonbad Kavous University, Golestan, Iran.
