Floating Net Cages is a fishery business developed in Banua Anyar, Banjarmasin City. A total of 544 cages are managed by the Banua Anyar community. The majority of cages in Banua Anyar are used to cultivate Bawal fish. In 2019 there was a sudden death of all the fish in Floating Net Cages. This case was happened because low value of dissolved oxygen and high water salinity. So the study must be done to find out whether the location of the Floating Net Cages is suitable based on the physical and chemical parameters of fresh waters. This study is to ensure the sustainability of the Floating Net Cages and environmental carrying capacity. This study has used spatial analysis to perform scoring, spatial join and overlay in Inverse Distance Weighting (IDW) to obtained some information on physical and chemical parameters. The results indicated that of the 25 Floating Net Cages sample points, a total of 19 sample points were declared potential for Floating Net Cage and 6 sample points indicate quite suitable for Floating Net Cages. If examined based on physical and chemical parameters, it is indicated that several parameters do not meet the optimal value for aquaculture. Physical parameters that indicate sample points are not optimal for cultivation include water depth, brightness and current speed. Chemical parameters indicating not optimal for cultivation include dissolved oxygen and salinity. Physical parameters that indicate sample points are not optimal for cultivation include water depth, brightness and current speed. Chemical parameters indicating not optimal for cultivation include dissolved oxygen and salinity. Physical parameters that indicate sample points are not optimal for cultivation include water depth, brightness and current speed. Chemical parameters indicating not optimal for cultivation include dissolved oxygen and salinity.
