Recreational fishing is a favorite activity around the world (Cooke and Cowx 2004) and particularly in areas for example North America (Arlinghaus and Cooke 2009). In Canada alone, over 3.3 million residents participated in recreational fishing in 2010 and collectively spent over 39 million angler days (DFO 2012). In 2006, in the USA, over 33.9 million residents went fishing at least once during that period (USFWS 2007). Recreational fishing supplies astounding socioeconomic advantages, and thus, many water bodies in North America are managed to maximize benefits for anglers and society (Arlinghaus and Cooke 2009; UN 2012). In recent years, there is an increasing realization that recreational fishing, regardless of the usage of modern fisheries management strategies, can have various adverse effects that extend beyond exploitation (McPhee et al. 2002). 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 casting, when equipment becomes entangled in debris). To highlight 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 fishing gear loss, translating to a loss rate of 0.0127 pieces per hour. Relating 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 discovered a variety of litter, including fishing line, lures and packaging from fishing gear (e.g. worm containers, tackle packaging). Bird 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 industry to 'get the lead out' through education plans and development of non toxic alternatives (Goddard et al. 2008). Baits can be ingested by a variety of organisms (reviewed in Cooke and Cowx 2006) and lost line may become entangled in critters (Derraik 2002) and has additionally contributed to degradation of coral habitats (Yoshikawa and Asoh 2004). Tackle loss has the possibility to generate difficulties for various wildlife, but birds have become the focus of most studies. Soft plastic fishing lures (SPLs) have been generally utilized in the angling community because the early 1970s. Soft plastic lures closely resemble natural forage and offer an alternative to cumbersome live lure. With growing issue for biosecurity and lure transport, there's additional recent curiosity about the usage of SPLs for a number of fisheries. Another benefit to the use of SPLs is that they are far stronger than live bait, permitting one to get multiple fish per lure. Following longevity and this lastingness is due to their being composed -biodegradable synthetic polymers. Currently, there are numerous brands and types of soft plastic lures, and for the most part, they are the same general composition, dampened plastic which contains phthalates added to another products that are similar or polyvinyl chloride. Similar tackle, SPLs have the capacity to be lost or discarded in terrestrial and aquatic ecosystems.
