An assessment of quantity, composition and seasonal variation of fishing-related plastic debris was conducted in six beaches along the Kerala coast of India during 2017-2018. Plastic items were the most dominant type of waste constituting 73.8% by number and 59.9% by weight. In the total debris recorded, 5540 pieces (36%) weighing 198.4 kg (39.8%) were fishing related trash. On an average 14.4 ± 12 fishing related items/100 m, corresponding to mean weight of 0.55 ± 0.7 kg/100 m was recorded from these beaches. Results indicated that the fishing-related plastic items were concentrated four times more in the beaches with higher fishing intensity, as compared to the other beaches. Also, the concentration of fishing-related plastic was recorded higher in the post-monsoon season compared to the lowest during monsoon, which was significant with p-value < 0.05. The results emphasize the role of fishing activities in the generation of marine litter.
2017年至2018年期间，对印度喀拉拉邦海岸沿线的六个海滩进行了与渔业相关的塑料垃圾的数量、成分和季节变化评估。塑料物品是最主要的垃圾类型，数量占73.8%，重量占59.9%。在记录的所有垃圾中，5540件（36%）、重198.4千克（39.8%）的垃圾与渔业相关。这些海滩平均每100米有14.4±12件与渔业相关的物品，平均重量为0.55±0.7千克/100米。结果表明，与其他海滩相比，渔业活动强度较高的海滩中与渔业相关的塑料物品集中程度高出四倍。此外，与渔业相关的塑料垃圾在季风后季节的浓度高于季风期间的最低浓度，p值<0.05，差异显著。研究结果强调了渔业活动在海洋垃圾产生中的作用。
