Description Observations on the stranded marine turtles and mammals in a stretch of 10 km at Gahirmatha
Beach, Orissa during 1983 to 1987 are reported here. The washed ashore marine turtles were due
to the result of turtles getting entangled and drowned in fishing operations conducted off Paradip
and adjacent area, the carcasses drifting northwards and ashore at Oahirmatha. In 1983 around
7S00 olive ridley Lepidochelys olivacea were washed ashore and the curved carapace length in cm varied
from 51-72 (62.2) and the carapace width in cm varied from 48-63 (57.8). The number of stranded
turtles was reduced to 360 in 1987 and this is due to the effective steps taken to enforce the Widlife
(Protection) Act by the State Forest Departments. Strandings of Humpback dolphin Soma
chinensis, Snubfln dolphin Orcaella brevirostris and Finless black propoise Neophocaena phocoenoides
were also recorded. Mortality of nesting females during arribada could have an adverse effect on the
breeding population of olive ridley visiting the rookery and consequently on recruitment. A careful
study is needed to take preventive and precautionary regulatory measures to be adopted in specific
type of fishing operations during the nesting season of olive ridley.
