Mesh size versus gear and craft type.

<p>All the fisheries except gill nets and ring seines appear to operate a distinct and fairly narrow range of mesh sizes. The mesh size of ring seines overlaps with gill nets however, ring seines have a much large range of mesh sizes. Kattumarams, small FRPs and vallams operate similar mesh sizes, however the range of mesh sizes operated is substantially larger in small FRPs and even more so with vallams. Trawlers operate nets with the smallest mesh sizes while big FRPs operate the largest, both within a narrow range. Note that values for line fisheries is size of hooks. Outliers were excluded to visualise the spread of the data.
