Description Non-biodegradable marine debris such as derelict fishing gears and their parts, polythene covers, carry bags,
synthetic packaging materials etc., cause serious damages to the benthic ecosystem including the marine biota.
We report here the monthly variation in the marine plastic litter (MPL) and its relative percentage to the quantity
of fish caught from the trawling grounds off Cochin, Ratnagiri, Mumbai and Veraval along the west coast as well
as Visakhapatnam from the east coast of India. The mean values of MPL from the fishing grounds registered the
maximum of 55.2 ± 16.52 kg/km2 off Veraval and the minimum of 2.11 ± 0.55 kg/km2 off Visakhapatnam,
registering a national average of 10.95 ± 3.05 kg/km2. The relative percentage of MPL over the fish catch
remained highest (3.83%) at Veraval and lowest from Visakhapatnam (0.33%) while, the national average was
1.89 ± 0.28. Monsoon season registered maximum MPL in the fishing grounds of all the coastal regions we
studied. Depth of the trawling grounds also influenced the quantity of MPL that 20 m depth registered quantity
(24.25 ± 9.16 kg/km2) and the overall mean at 10 m and 40 m depth zone are significantly different from that
of 20 m. The database created through this study are discussed in the light of increasing deleterious effects of
plastic pollution in the active fishing areas in coastal region and the urgent need to save the sea for sustainable
use of its resources.
