Monthly litter samples were collected from three major beaches in Mangaluru from 2011-2016. Fishing litter persisted at the beaches, resulting in higher abundances by number (59%) and weight (33.4%) relative to all litter in 2016. In addition to plastics, foam comprised 7.14-11.0% of total litter. Significant positive correlations were observed between the amount of plastic on the beaches and rainy days, rainfall, and river discharge. The maximum river discharge coincided with an increase in plastic items on the beach. Yearly quantities of plastic items (p < 0.01), plastic bags (p < 0.001), and plastic footwear (p < 0.05), on the beaches were significantly different indicating clean-up activities reduced the litter quantity. Changes in total beach litter revealed that Panambur Beach, a fishing boat landing centre was the least changed, and thus appropriate incentive-based management options for the resident fishermen could result in collection and elimination of litter.
每月从芒格洛尔的三个主要海滩收集一次垃圾样本，时间为 2011 年至 2016 年。钓鱼垃圾在海滩上持续存在，导致 2016 年的数量（59%）和重量（33.4%）均高于所有垃圾。除了塑料，泡沫占总垃圾的 7.14-11.0%。海滩上的塑料量与雨天、降雨量和河流流量之间存在显著的正相关关系。最大的河流流量与海滩上塑料物品的增加相吻合。海滩上塑料物品（p<0.01）、塑料袋（p<0.001）和塑料鞋（p<0.05）的年数量存在显著差异，表明清理活动减少了垃圾量。海滩上总垃圾的变化表明，作为渔船登陆中心的 Panambur 海滩变化最小，因此，为当地渔民提供基于激励的管理选项可能会导致垃圾的收集和消除。
