Abstract This study was conducted to find out the effect of the addition of three types of plant oils (mint, chamomile, and ginger) on productive and immune performance in common carp fish Cyprinus carpio L. Used 120 fish with an average weight of 250 ± 4g, randomly distributed over four treatments with three replicates, with 10 fish per replicate. Used Four treatments: the first control (T1) without additives and the second treatment (T2), adding peppermint oil by (0.5%), the third treatment (T3), adding chamomile oil by (0.5%), and the fourth treatment (T4), adding ginger oil by (0.5%). Fish were fed on experimental diets by 5% of the live weight divided into two meals per day and the trial continued for 128 days, including 8 days for the adaptation period. Measured Some growth criteria for assessing the effect of diets and Some environmental tests were taken as. The results showed significant differences between the treatments (p<0.05), the chamomile treatment (T3) and the mint treatment (T2) outperformed the rest of the treatments in the growth criteria as they recorded the highest weight increase rate, respectively, reaching 656g and 609g and also recorded the highest weight increase rate of Respectively 405g and 358g. Also, they recorded the highest food conversion rate (FCR), respectively, 3.0 and 3.14 gm/g weight gain and the highest food transfer efficiency rate (FCE), respectively, were 33.36 and 31.82%. They also recorded the highest daily growth rate (DGR), respectively, of 3.38 and 2.99 g/day. It recorded the highest qualitative growth rate, respectively, 1.88% and 1.80%. The conclusion of this study is that the use of oils (mint, chamomile and ginger) with a concentration of 0.5% in diets of common carp fish has improved productive performance. Key words: Fish, Mint ,Chamomile, Ginger. Introduction Aquaculture is the fastest growing sector in animal food production, with fish contributing about 17% of the proteins consumed by the world’s population In view of this importance, global production of aquaculture has increased, reaching in 2016 (53.367) million tons, with an average of 20.3kg of fish per person per year. (FAO, 2018). However, aquaculture’s growth is often associated with intensification of agriculture, which leads to overcrowding and poor water quality, And facilitate the spread of pathogens and increase disease outbreaks and, as a consequence, the occurrence of deaths ( Bondad et al., 2005). In order to avoid economic losses related to health deficiencies, veterinary medicines are widely used in fish farming for disease prevention and treatment. (Rico et al., 2013). While the extensive use of synthetic drugs presents many imperfections for both the environment and health, and the extensive use of antibiotics has led to their accumulation in fish tissues (Cabello et al., 2006). Therefore, medicinal plants can provide a cheaper and more sustainable alternative to chemotherapy in aquaculture, as it has been shown to show many vital effects such as anti-stress, And immune stimulants against parasitic, bacterial, fungi, external viruses and parasites (Reverter et al., 2012). In addition, its use can reduce treatment costs and be more environmentally friendly as it is more biodegradable than synthetic molecules, It is also less likely to produce drug resistance due to the wide variety of plant extract molecules (Olusola et al., 2013). *Author for correspondence : E-mail : qasimsultan80@gmail.com
