Abstract

The average annual yield of finfish from Negombo lagoon (7°10'N and
79°50'E) was estimated to be around 15 kg/ha. About 36% of the catch came
from brush parks, while encircling nets contributed for 28%; the gill nets and
modified set nets contributed for about 20%. The maximum sustainable yield
(MSY) was calculated using Schaefer's "surplus yield" model. The results show
that an increase in the use of gill nets and a decrease in the use of modified
set nets may increase the present catch towards MSY. The catch from other
gears appears to be very close to the level of MSY.
