| Abstract | An assessment was made of the impact of major carp hatchling and fingerling
stocking in beels in the North-eastern floodplains of Bangladesh.
Carp production from beels (perennial water bodies) artificially stocked
with major carp hatchlings was significantly higher (P<0.001) than non-stocked
bee ls, which was due to the artificial stocking of carp hatchlings. Total
production rate (per ha ) was relatively higher in larger bee ls than smaller, both
stocked and non-stocked. Rohu, cat la and t o some extent common carp were found
to be more s uccessful species in the floodp lain.
Leaseholders of all categories of beels were found to benefit most from the
stocking program as their income increased considerably.
The over al1conclition of the fishermen households surveyed improved a
little over the four years period from prestocking to poststocking. A significant
increment occurred in the ownership pattern of fishing gears, but the change in
other property ownership were found to be insignificant, no change in some cases.
Income from fishing increased, which reflects the impacts of stocking but its
percentage in total income decreased in the poststocking time, and a shifting
tendency to other occupations was observed.
It can be concluded that stocking resulted in both higher production and
income from beel fisheries, but poor fishermen did not benefit considerably from
the program.
The implication of these findings for management of the stocking program
and beel fisheries is described, as we ll as possible environmental impacts |
