Food preferences of nilem carp (Osteochilus hasselti) at paddy-fish culture pond in Kuningan, Garut and Tasikmalaya, West Java Province

The research aims are to determine the availability of natural feed resources and to study the food habits of nilem carp (Osteochilus hasselti) in the paddy-fish culture system in Kuningan (300 m from sea level), Garut (700 m from sea level) and Tasikmalaya (500 m from sea level) districts.

Description
Summary:The research aims are to determine the availability of natural feed resources and to study the food habits of nilem carp (Osteochilus hasselti) in the paddy-fish culture system in Kuningan (300 m from sea level), Garut (700 m from sea level) and Tasikmalaya (500 m from sea level) districts. The research used a survey method with descriptive analysis. The treatment was without commercial feeding so that it utilizes natural feed, and consists of two replications in each location. The research was conducted in August 2018 - May 2019. The fish used was java carp with a length of 5-7 cm and a stocking density of 2000 fish/paddy field 200 m2. The results showed that there were two types of feed composition, namely phytoplankton and zooplankton. The preponderance index of nilem carp in each location generally utilizes phytoplankton from the phylum Bacillariophyta as its main feed. The index of electivity shows that the preference level of Java carp for phytoplankton has similarities in each region. Its mostly preferred phytoplankton, such as Cyclotella, Gomphonema, Gyrosigma, Navícula, Nitzschia, and Synedra from Bacillariophyta and Closterium, Coelastrum and Cosmarium from Chlorophyta.
