Abstract

The fish community in beels in the Sylhet-Mymensingh basin in Bangladesh
changed dramatically from 1967-1973 to 1984. The dominant species of carp in
the community shifted from large Labeo rohita, Catla catla, Cinhinus mrigala
and Labeo nandina to small Labeo calbasu, Labeo gonius and other miscellaneous
fishes. Major carp populations (L. rohita, C. catla and C. mrigala) which were
composed of large age 1+ and 11+ fish in 1967-1973 changed to populations
which primarily consisted of small age 0+ fish in 1985. The above changes in
the fish community and major carp population structures suggest that overfishing
is a major cause for the scarcity of large fish and decline in major carp stocks
in beels in the Sylhet-Mymensigh basin.
