Abstract
With the nationwide spread of tourist attractions like campgrounds, recreational fishing, and fish farming, there are concerns over environmental degradation of rivers. This research has used the AGP (Algal Growth Potential) test to conduct studies on reservoir algae (Microcystis aeruginosa) proliferation testing, caused by fish farming, and artificial fishing bait (paste bait). The following conclusions were as follows. Artificial fishing bait (paste bait) greatly associates with the proliferation of Microcystis aeruginosa. In the algae proliferation testing using river water sampling, it was thought that releasing fishing bait into reservoirs was the cause of the eutrophication phenomenon.
