THE EFFECT OF ENVIRONMENTAL PARAMETERS ON PLANKTON ABUNDANCE IN JATIGEDE RESERVOIR, WEST JAVA

Fisheries

ABSTRACT The water flowing to Jatigede Reservoir can affect the condition of the waters both physically, chemically and biologically. The correlation between physical-chemical parameters of water affects the life of the organisms below. The purpose of this research was to determine the physical-chemical parameters of the waters that more affect the distribution of plankton in the waters. The research was conducted from August 2019 to October 2019 at the Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Sciences, Padjadjaran University. This study used a survey method. Sampling was carried out at 4 stations on the surface, half compensation and compensation depth. The parameters analyzed were the physical and chemical parameters of the waters, the abundance and composition of plankton, and the multivariate analysis of CCA. Metering of physical-chemical parameters of water includes nine parameters, such as transparency, temperature, current velocity, pH, CO2, BOD5, DO, Nitrate and Phosphate. The results showed that the average phytoplankton abundance in the Jatigede reservoir during the research ranged from 6,978-15,069 ind/L and the range of 100-312 ind/L for zooplankton. A total of 49 genera from 22 orders and five phytoplankton phylum as well as 17 genera from 9 orders and 5 zooplankton phylum have been identified. Temperature and nutrients are the parameters that most affect the distribution of phytoplankton, while for zooplankton are temperature and depth.
