Abstract
Effect of incorporation of square mesh panels in stationary bag nets operated in Hooghly
estuary (West Bengal) on fish landings was studied through comparative fishing experiments.
The results showed that catches of juveniles of prawns and finfishes was significantly lower
in the experimental gear with square mesh panels of 20 mm bar mesh size, compared to
the control net. 50% retention lengths (L ) of Metapenaeus sp. and Macrobrachium mirabk,
Macrobrachium lamerri and sciaenids were also higher in the experimental bag net compared
to the control net. Results indicated that provision of square mesh panels in bag nets would
help in the conservation and management of estuarine fishery resources
