WATER QUALITY INSPECTION DEVICE AND BREEDING SYSTEM

To provide a water quality inspection device that determines water quality on the basis of the amount of microorganisms fixed to a filter medium.SOLUTION: A water quality inspection device for a breeding system 10 including a breeding tank 20, includes a water quality control tank 40 connected to the breeding tank 20 and through which breeding water circulating in the breeding system 10 is circulated, a filter medium 42 stored in the water quality control tank 40, an exterior water source 70 that subjects the filter medium 42 to a germicidal treatment, a turbidimeter 44 that measures turbidity of the breeding water in the water quality control tank 40 after the exterior water source 70 subjects the filter medium 42 to the germicidal treatment, and a control device 80 that determines water quality on the basis of the turbidity.SELECTED DRAWING: Figure 1 【課題】濾材に定着した微生物の量に基づき水質判定する水質管理装置を提供する。【解決手段】飼育槽２０を備える飼育システム１０用の水質検査装置であって、飼育槽２０に接続されており、飼育システム１０内を循環する飼育水が流通する水質管理槽４０と、水質管理槽４０に収容されている濾材４２と、濾材４２を殺菌処理する外部水源７０と、外部水源７０が濾材４２を殺菌処理した後に、水質管理槽４０内の飼育水の濁度を測定する濁度計４４と、濁度に基づき水質を判定する制御装置８０と、を備える。【選択図】図１
