Abstract :

In this research، The possibility of intelligent management of water qualitiy conditions in Common carp culture was investigated during one month. To perform the study، one intelligent instrument that is constructed by the authors was used in this research. The instrument was equipped with Program Logic Control(PLC) and sensitive sensors for control of three important water parameters including، temperature ،Oxygen and pH.  Three above parameters which are crutial  for   Common carp culture  were adjusted on optimum levels ،temperature at (25Co)،Oxygen at (8 mg / li) and  pH at( 7.3).                                                                               In each contianer (aquariums) fingerlings 5 to 10gr were released. This instrument could be controll remotely by camera and communication equipments like mobile، telephone and internet. Three other aquariums also were prepared as control group which on them، the above parameters،where countrolled manually. They were checked three times a day during the study.The three mentioned parameters (tempruture ، O2 and pH)in the quiped containers  were exmind countiusely and atumatically duiring whole period of expriments. On equipped aquariums during 31 days، 13 speciemen،out of  15 alive til end of the study. They seems to be healthy and shows a good growth،which can be considered as a result of favorate invironmental conditions (temprature،O2، pH) After 31 days period of study، the average  weight of treatment fishes were reached form 5-10gr to 250±8gr. But in 3 control group ،parameters meet a great flactution،vz: tempruture(18-29ºC)، Oxygen (5-12)، and pH (5-9)، leading all control group،s  speciemens being died til end of days of expriment. Result show،s that this instrument(PLC)،can successfully being used for water management of carp cuture ponds.
