• The aquaculture field of recirculating and filtering type, high density breeding system in the problems of the yield efficiency and the treatment of waste water, are being used. In the aquaculture field of the recirculating and filtering type, nitrofier bacteria are used to remove Ammonia effecting very harmful for fish life and deterioating water quality. However, the problem of this system causes water to be deteriorated and a lot of fish to be died because the water qualiy becomes worse by Ammonia generated due to the discharges of fish and feed stuff not to be fed. So the methods producing a cluster of nitrofier bacteria by recirculating the sludge with a lot of nitrofier bacteria, and fixing a cluster of nitrofier bacteri, on filter plate by using a lot of activated sluge makes the water quality better in microbiological aspect. But, it takes a long time to grow the nitrofier bacteri, by fixing them on filtering plate. So it also takes a long time to keep them in adequate level when a part of bacteria died off. In this paper, the measurement and control system analizing the microsopic image obtained from CCD camera and keeping them in the suitable level by measuring the number of nitrofier bacteria, in the bioreactor in a real time is developed in order to solve this problem. Alcaligenes sp., Pseudomonas sp., acinetobacter sp., and Acinetobacter sp., are used in this experiment. Nitrofier bacteria are fed from the bioreactor by the sampling device, their images from CCD camera are stored in computer and analized by the image processing method. They are binarized, classified and compared to thier microbiological prior knowlege. The result suggested in this paper are compared to the result analized by the vision of microbiology expert, and its effectiveness is proved.
