Abstract
The paper deals with an experiment with a floating trawl net
off Cochin, using a pair of curved otter boards and a transducer
mounted on the head rope of the net. 32 hauls were made with
different towing speeds and warp length keeping one factor constant
for varying parameters of the other factor. The working data for
32 hauls are presented and the effect in the fishing depth of the net
due to the variation in one factor is mentioned. The 'fishing depth'
is indicated in this paper as the distance between the head rope and
the bottom. The usefulness of similar experiments with an added
information on the angle of leading warp at the stern for the exploitation
of column fishes in Iodian waters is indicated in this paper.
