Abstract: |
Fish catch data were collected for' a period of 5 years (1994 to 1998) from three major
lakes of Pokhara valley, Phewa, Begnas and Rupa. Catch statistics were analyzed to
depict the fisheries management issues for future. Fishing gear survey interviews were
conducted in 1998 to assess the degree of fishing efforts and pressure on the fish
resources in the lakes of Pokhara valley. Twenty four species of fish, of which 17 native,
were found in catch from the lakes of P.okhara valley. The total catch of fish was higher
in lake Phewa (50. 7 t)fol/owed by lake Begnas (42.3 t) and the lowest were for lake Rupa
(8.0 t) during 1998. Species contribution to the total catch of individual lakes was varied
greatly. Rohu dominated in catch for the recorded lakes. Seasonal pattern of fish catch
was almost similar for these lakes. About 65-70% of the total catches occurred during
September to March during the year 1994-98. Growth rate of catch yield increased by 4. 3
and 6. 6% every year for lakes Phewa and Begnas, respectively for a period of 1994 to
1998 whilst the catch decreased by 10.3% every year during the same period in lake
Rupa. Contribution of native fish in total catch was decreased by 12. 7% every year
during 1994 - 98. · Possible reasons for decline of native fish in catch have been
discussed Three major types of fishing ·gear, gil/nets, cast nets an4 fishing hooks were
found in the lakes of Pokhara valleY: The gi/lnet was the most common fishing gear
operated by fisher men with an average holding area of 5494, 5797 and 949 m2
•
respectively for lakes Phewa, Begnas and R'"fa. The most common size of gil/net
operated in these lakes ~as between 350-450 m. Likewise the mesh opening (stretched).
of gil/nets varied greatly from 15 to 400 mm, irrespective of water bodies. The
effectiveness of gill net in catch was only 0. 36 kglm2 !year for the lakes of Pokhara valley.
The pressure of fishing gear on the lake fisheries resources has been analyzed and
imprQvement measure~ have been suggested |
