Cetacean interaction with fishing gear has been
reported widely around the globe. This study is
aimed at finding out the fishery most prone to
cetacean attack along the Indian coast, and to
identify the species causing the attacks, the extent
of damage to fishing gear, the seasonal variation and
catch loss in different fisheries and suggest mitigation measures. This was assessed by conducting face
to face interviews with the crew and owners of the
fishing vessels from 20 major harbours along Indian
coast. The results of the study show that cetacean
fishery interactions are frequent in all type of fishing
gears operated in the country. Small gillnets that
operate near the shore are most prone to cetacean
attacks. Gear damage and depredation by cetacean
and non-cetacean species cause economic loss to the
tune of Rs. 0.5 – 2.0 lakhs per incident in gillnet and
purse seine/ ring seine fishery. The study shows that
about 15.3% of respondents reported incidental
bycatch of cetaceans, mainly in gillnets, purse seines
and trawls. The number of interactions are found to
be maximum during pre-monsoon season. It has
also been observed that gillnets and purse seine/
ring seine are the most economically affected
fisheries. Fishers employ mitigation measures like
scaring away the animals or delaying fishing. The
use of acoustic pingers can be considered as a
management option in India.
