Dimethoate pesticide and bacilar bio-fertilizer are two common inputs widely used in Iranian agriculture which washed by run-off and transmitted to aquatic ecosystems where they can cause biological and physiological problems for aquatic organisms. The objective of this research was to study the combined effects of dimethoate pesticide and bacilar bio-fertilizer on blood biochemical parameters of common carp. To this end, 270 fish were selected and allocated into 9 treatment including: control group, treatment A (0.016 mg/L pesticide), treatment B (0.032 mg/L pesticide), treatment C (0.1 ml/L fertilizer), treatment D (0.2 ml/L fertilizer) and combined treatments AC, AD, BC, BD, in triplicate. Fish were exposed to different concentration of dimethoate pesticide and bacilar fertilizer for 14 days. The blood biochemical parameters including Triglyceride (TG), Cholesterol, Glucose, Protein, Albumin, and Globulin were measured. The amount of TG in treatments A, C and D showed significant increment in comparison with control group. The amount of Cholesterol in treatments A and B had been increased in comparison with control group but in treatment AD had been decreased. The amount of Glucose showed no significant differences in all treated groups in comparison with control group. Protein had been increased in treatments C, D and other combined treatments except AC. The amount of Albumin in all treatments except A had significantly increased. The amount of Globulin in all treatments except B did not have any significant differences with control group. The results of this study revealed that combined treatment of dimethoate and bacilar bio-fertilizer did not showed remarkable differences from their singular treatments and more research with higher concentrations of pollutants are required for better understanding of their interactional effects.

In recent years, the global trade of ornamental fish has been a significant growth, so that Asia and other countries such as Sri Lanka and South-east Asian countries could use this potential to export this type of fish to other countries. Considering the importance of ornamental fish, the efforts to reduce stress is one aim of the ornamental fish farmer to reach more growth and production. Besides using the other new technology for alleviating the effects of stress through changes in physiological parameters related to blood and body tissues of fishes, music as stress reducer factors is more considered, recently. Music as a controllable factor in cultivating is reported by many researchers, to achieve more benefits by lower cost. This article reviews the effects of music on some ornamental fish species.
