Abstract

Abstract. Epipelic diatom lives by attaching on sediment. Its existence is strongly affected by water and sediment qualities. The purpose of this research was to analyze the structure of epipelic diatoms in shrimp pond bottom and the correlation between epipelic diatom diversity with water and pond bottom sediment qualities. This explorative research was conducted on 12 shrimp ponds during water preparation period (pre-stocking). Data were collected to analyze the correlation between water and sediment qualities. The results showed that Nitzschia and Pleurosigma were the dominant epipelic diatoms in shrimp pond. Epipelic diatom diversity in shrimp ponds were affected by water quality parameters, namely total alkalinity, organic matter, and nitrate, as well as sediment quality parameters, namely cation exchange capacity, clay content, and organic matter content. Keywords: Epipelic diatom, lens tissue trapping method, Nitzschia, Pleurosigma
