Abstract Fishing experiments were undertaken to study the relative utility
of a newly designed four seam type net on a conventional two seam
net at the centre along the East Coast in both inshore and deeper
zones (upto 100 m.) and the results indicated that the new four seam
net has given higher catch rate of 6 to 8% more with higher catch
rate of fish supposed to belong to off bottom region. Further this
gear found more selective in obtaining Lactarius, which is one of
the good variety of fish from trawlers, in both quantity as well as
in quality. In terms of horizontal spread this new net gave less
on comparison with the. conventional two seam net, thereby showed
corresponding increase in vertical spread; but warp tension remained
more or less same in both the gear, Both gear have worked equally
well in majority of depth ranges experimented with optimum spread.
Finally the results indicated that the new net can work well from
the present trawlers along the coast.
