Abstract

The results of the study of traditional shrimp fishery in the Negombo lagoon are presented. Fishing was mainly conducted by traditional dug out canoes and log rafts. Trammel nets, brush piles, cast nets, drag nets and stake-seine nets were the major fishing gears employed. The estimated mean catch rates
for trammel nets, brush piles, cast nets, drag nets and stake-seine nets were 4.15, 5.92, 0.65, 13.33 and 23.21 kg/operation respectively in 1998 and 5.18, 7.09, 0.7, 15.68 and 26.19 kg/operation respectively in 1999. The annual total
catch was estimated at 827 MT in 1998 and 1024 MT in 1999. Stake nets, drag nets, trammel nets and cast nets caught more shrimps and brush piles favoured fish catches. The highest income/fishing operation was estimated for stakeseine
nets (Rs. 2 050.00), while the lowest was for cast nets with Rs. 115.00/ operation. In the stake-seine net fishery, the fishing community itself has formulated a mechanism for equity sharing.
