Analisis Isi Lambung Ikan Katung (Pristolepis Grootii) Di Danau Lubuk Siam Kecamatan Siak Hulu Kabupaten Kampar Provinsi Riau
Pristolepis grootii is one of freshwater fishes that inhabit the Lubuk Siam
Lake in the Kampar Regency. The information on the feeding habit of that fish,
however, is rare. To understand the type of food consumed by that fish, a research
has been conducted in January to February 2020. Sampling was conducted once/
two weeks interval for a two months period. There were 96 fishes captured, but 22
of them had empty stomach and they can not be used for stomach content
analysis. The analysis was conducted using a volumetric method. Stomach content
was analyzed as a basis to calculate the Preponderance Index (PI). Results shown
that the main food of the fish in Lubuk Siam Lake was plant (PI 55.50%) and
insect (PI 40.50%), another type of food was fish, crustacean and unidentified
debris which classified as additional food (PI was 2.67%, 1.02% and 0.32%
respectively). Data obtained indicate that this fish can be categorized as omnivore.
