Accessibility the fry of Mugil cephalus to the extract of Camellia sinensis concerning growth performance and haematology indices

Nowadays, Researchers are looking for approaches to eliminate or minimize the application the antibiotics in aquaculture industry. The purpose of this study was to determine accessibility the fry of Mugil cephalus to Camellia sinensis concerning the growth performance and haematology parameters. One hundred and fifty fry of M. cephalus with an average weight of 2.15 ± 0.08 were collected from Chabahar coastal waters and transferred to the experimental site, under the optimal conditions. This research was based on 3 treatments, one control in triplicates, 0, 50, 100 and 200 ppm of C. sinensis. The main index should be measures in this study were included the growth factors containing mean weight, daily growth, and haematological factors, ultimately. Overall, the results of this study showed that adding 200 mg kg-1 of GTE (Green Tea Extract) of diet resulted in a significant increase in final weight and daily growth index (DGI), especially during the first 4 weeks of fry M. cephalus rearing, compared with the control group. Increasing the green tea extract to diet caused no significant increase in the number of RBC compared to the control. The number of white RBC increased in the treatment containing 200 mg kg-1 of green tea extract. The highest amount of hemoglobin (Hb) was measured in the group of 200 mg kg-1 GTE. The lowest amount of hematocrit (Hct) was observed in the treatment containing 100 mg kg-1 GTE and its highest was measured in treatment containing 200 mg kg-1 GTE.
