Abstract

Phytoplankton in an intensive system of white shrimp cultivation is useful as an indicator of the water quality. Blue-green algae are a group of phytoplankton that has an important role, although there are several disserve species. Blue-green algae are an abundant primary producer and can be found a lot both in freshwater and in the sea. Blue-green algae are also a potential bio-indicator to designate how good or bad the water condition is. This research aimed to determine the correlation of the ratio dynamic of N:P toward the abundance of Blue-green algae within the system of a Vaname (Litopenaeus vannamei) shrimp pond. The main parameters observed were ammonium, nitric, nitrate, phosphate and the abundance of blue-green algae, as well as the supporting parameters of pH and the clarity of the intensive system of the Vaname shrimp pond in Banyuwangi. Based on the data analysis and study of the dynamic ratio correlation of N:P toward the abundance of Blue-green algae, it can be concluded that ratio of N:P influences the level composition of phytoplankton in water cultivation. The difference in the levels of ammonium, nitric and phosphate influence the abundance of Blue-green algae in the water. A high level of ammonium and low level of nitric causes a high level of abundance of Blue-green algae.
