Recreational fishing is a well-known activity round the earth (Cooke and Cowx 2004) and especially in regions including North America (Arlinghaus and Cooke 2009). In 2006, in the USA, over 33.9 million residents went fishing at least once during that period (USFWS 2007). Recreational fishing supplies huge socioeconomic benefits, and therefore, many water bodies in North America are managed to maximize gains for anglers and society (Arlinghaus and Cooke 2009; UN 2012). Lately, there is an increasing realization that recreational fishing, despite the usage of contemporary fisheries management strategies, can have various adverse outcomes that extend beyond exploitation (McPhee et al. 2002). Specifically, there are an increasing variety of reports of environmental pollution and degradation attributed to angling actions (Cooke and Cowx 2006; Lewin et al. 2006).Recreational angling can generate pollution through a variety of sources including the use of combustion boat motors (noise, creation of hydrocarbons, fuel spills) and the deposit of fishing tackle (e.g. fishing line, lead sinkers, lures) and affiliated bedding material (e.g. packaging from fishing stuff). Fishing gear is lost haphazardly by irresponsible anglers (i.e. trashing) and, more generally, as unintentional loss by responsible anglers (e.g. when line breaks during a failed cast, when gear becomes entangled in debris). To emphasize the potential magnitude of gear loss, a study in Minnesota (Radomski et al. 2006) interviewed 8,068 boat anglers for five walleye (Sander vitreus) fisheries and found 80 % of anglers reported tackle loss, translating to a loss rate of 0.0127 pieces per hour. Associating this to angler numbers and hours spent fishing, this equated to over 100,000 lead-based things lost in the summer of 2004 alone. O'Toole et al. (2009) surveyed bank fishing sites in Ontario and uncovered a variety of litter, including fishing line, lures and packaging from fishing gear (e.g. worm containers, fishing gear packaging). Fowl ingestion of lead sinkers is well examined (Scheuhammer and Norris 1996; Franson et al. 2003), and there are a variety of efforts underway by authorities, anglers and the fishing sector to 'get the lead out' through education programs and development of non toxic alternatives (Goddard et al. 2008). Hooks can be ingested by a number of organisms (reviewed in Cooke and Cowx 2006) and lost line can be entangled in animals (Derraik 2002) and has also contributed to degradation of coral habitats (Yoshikawa and Asoh 2004). Fishing Gear loss has got the potential to generate problems for a variety of wildlife, but birds have become the focus of the majority of studies. Soft plastic fishing lures (SPLs) have been generally used in the angling community because the early 1970s. Soft plastic lures strongly resemble natural forage and supply an alternate to cumbersome live bait. With growing concern for bait and biosecurity transfer, there is added recent interest in the use of SPLs to get a variety of fisheries. Another advantage to the use of SPLs is that they are considerably stronger than live bait, allowing one to get multiple fish per lure. This durability and following longevity is a result of their being composed of inert non -biodegradable synthetic polymers. Now, there are numerous brands and kinds of soft plastic lures, and for the large part, they're the same general composition, dampened plastic which includes phthalates added to other products that are similar or polyvinyl chloride. Similar tackle, SPLs have the capacity to be lost or discarded in aquatic and terrestrial ecosystems.
