Abstract

Phytoplanktons are a supporting microorganism within the activities of vannamei shrimp cultivation. Phytoplankton are useful to control the color and clarity of the water, increasing the dissolved oxygen (DO), controlling the growth of weeds in the bottom of the pond, and absorbing the abundance of organic compounds in the water such as ammonium, nitric and nitrate. This research aimed to find out the influence of the ratio dynamic of N:P toward the abundance of phytoplankton in an intensive system shrimp pond. The main parameters observed were ammonium, nitric, nitrate and phosphate, as well as the abundance of phytoplankton. The study was being held in the laboratory of PT Surya Windu Kartika Banyuwangi, and measurements were also taken of the supporting parameters of pH, clarity, and salinity. The results of the data analysis and study revealed that the dynamic composition of ammonium, nitric, nitrate and phosphate influences the dynamic composition of the phytoplankton in the water. The increasing nitric levels affect and increase the composition of Bacillariophyceae and decrease the abundant composition of Cyanophyceae. An increase in the level of ammonium in the water causes an increase in the abundant composition of Cyanophyceae and a decrease in the abundant composition of Bacillariophyceae, and dynamic PO4 influences the dynamic abundant composition of phytoplankton classified as Bacillariophyceae and Cyanophyceae.
