ON THE OPERATION OF SMALL SHRIMP TRAWLS IN SHALLOW WATERS-SCOPE-RATIO AND Sl E .. DEPTH RELATION

Abstract

Studies on small trawls seem to be comparatively less. These
trawls are generally operated in shallower waters, where due to the
limitations in the length of warp that could be released, size
restrictions have to be considered for their efficient functioning. An
attempt has been made to assess the effective scope-ratio of length of
warp required for the operation of trawls at shallower depth and to
a judge the size oftrawl suitable for use at lower depths.
