THE EFFECT OF PHYSICAL-CHEMICAL FACTORS ON THE EXISTENCE OF KURAU FISH IN MARO ESTUARY OF MERAUKE DISTRICT

This study aims to analyze the influence of physical and chemical factors on the existence of Kurau Fish (Eleutheronema tetradactylum) in the Maro River Estuary of Merauke Regency. Data collection was carried out by measuring the environmental parameters directly, namely temperature, salinity and pH, while the fish catch data of Kurau was obtained by calculating directly the number of catches per trip with the data amount of 34 data. Environmental factor data and catch results were tested statistically using regression models. The results showed that environmental factors that influence the presence of Kurau Fish in the Maro River Estuary are water temperature and salinity.
