Food Habits Study of Cultured Nilem Fish (Osteochilus hasselti C.V.) on Minapaddy at Agriculture Area of Talagasari Village, Kadungora District, Garut Regency and Indonesia

Abstract

This research was conducted in May 2018 until September 2018, aimed at analyzing the eating habits of nilem fish which are kept in the waters of CV Agri Insan Mandiri, Tegalsari Village, Kadungora District, Garut Regency, West Java. The research method used was purposive sampling for sampling water quality and plankton abundance, as well as simple random sampling method for sampling nilem fish as a data source for eating habits. Data on mineral content in dissolved soil and minerals in the waters is used as supporting data that determines the presence of natural feed. Based on the results of this research, it was found that in the Minapaddy waters found 7 phyla including Bacillariophyta, Euglenophyta, Chlorophyta, Cyanophyta, Ochrophyta, Cryptophyta and Rodophyta. Bacillariophyta and Euglenophyta are the most common phyla. Natural feeds favored by nilem fish come from Bacillariophyta with a total of 10 genera, while those that are not favored come from Euglenophyta with 2 genus. The composition of dissolved minerals Calcium (Ca), Potassium (K), Iron (Fe) and Silica (Si) exceeds the normal requirements for phytoplankton, especially Bacillariophyta, so that the abundance of plankton is comparable to Euglenophyta which is not utilized by nilem.
