Abstract
Gut content analysis is an approach which
provides insights into feeding behavior, dietary composition and feed
preference of fish species. A total of 36 guts of Mastacembalus armatus of
Begnas Lake were collected from December 2023 to March 2024 from the fish
landing site of Begnas Lake. The growth pattern of Mastacembalus armatus
was found to be negative allometric, with a growth coefficient (b) of 1.7667.
The gut content analysis showed that Mastacembalus armatus mainly feeds
on animal-based items, with prawns (52.99%) being the most abundant food
source, followed by fish (33.46%), aquatic insects (8.26%), zooplankton
(4.05%), chironomid larvae (0.78%), and phytoplankton (0.46%). These findings
indicate that Mastacembalus armatus is predominantly carnivorous.
