Abstract
A study on gut content analysis of fish species that are captured around the
floating caged fish culture area in the Koto Panjang Dam, Kampar, Riau Province has
been conducted on June to September 2007. Aims of this research are to understand the
type of fishes present aroimd the cages, their food types and also their role in reducing the
amount of organic materials originated from fish culture activities. Fish samples were
caught by scoop nets and fishing lines and gut content was analysis using a volumetric
method.
Results shown that 9 fishes species namely goramy (O^hronemus gouramy ),
tambakan {Helostoma temincki) , kapiek {Puntius schwanefeldi), paweh {Osteochilus hasseiti),
common carp (Cyphnus carpio ), sipaku (Cyclocheleichthys apogon), nile tilapia
{Oreochromis niloticus), ingir-ingir (Macrones nigriceps) and baung (Macrones nemurus) are
able to eat pellets and fish remams that may present around the cages. Other species, such
as belida (Notopterus notopterus), toman (Ophiocephalus micmpeltes), gabus {Ophiocephalus
striatus) and tapah (Walfago lean), prey on fish and shrimp only. The stomach of another
fish species captured, namely katung fish (Pristolepis grotif), however, fiill of algae. Based
on the data of stomach content, it can be concluded that fish that have ability in eating
pellet remains present around the cages may have important role in reducing the amount
of organic materials originated from floating cages aquaculture
