Abstract
The mullet is a fish that dominates the Lampon Estuary. These waters contain Pb and Hg that exceed the threshold. This study aims to look at the mullet food habits, water quality, and the relationship between water quality and mullet food habits. This research was conducted for three months, from November 2019 to January 2020 at Estuary Lampon, Pesanggrahan, Banyuwangi, East Java. This research used a survey method (non-experimental) and observation method. The number of fish samples was 171 fish. Based on the analysis, the composition of mullet fish feed consists of Diatoms, Flagellates, Chlorophyceae, Bacillariophyta, Xanthophyta, and Dinoflagellates. The composition of plankton as food in polluted waters obtained a different type of plankton from normal waters. Based on the index value of food choices, the most popular food is Diatoms and can be categorized as herbivorous fish.
