Recreational fishing is a well-known activity round the world (Cooke and Cowx 2004) and particularly in regions including North America (Arlinghaus and Cooke 2009). In Canada alone, over 3.3 million residents participated in recreational fishing in 2010 and put together 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 massive socioeconomic gains, and thus, many water bodies in North America are managed to optimize gains for anglers and society (Arlinghaus and Cooke 2009; UN 2012). In the last few years, there has been a growing recognition that recreational fishing, regardless of the utilization of modern fisheries management strategies, can possess a variety of adverse consequences that extend beyond exploitation (McPhee et al. 2002). Specifically, there are an increasing number of reports of environmental pollution and degradation attributed to angling activities (Cooke and Cowx 2006; Lewin et al. 2006).Recreational angling can create pollution through a variety of sources including the use of combustion boat motors (sound, generation of hydrocarbons, fuel spills) and the deposit of fishing tackle (e.g. fishing line, lead sinkers, lures) and affiliated litter (e.g. packaging from fishing materials). Fishing gear is discarded haphazardly by irresponsible anglers (i.e. trashing) and, more commonly, as unintentional loss by responsible anglers (e.g. when line breaks during a failed casting, when equipment becomes entangled in debris). To accentuate the potential magnitude of equipment 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. Connecting 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) studied bank fishing sites in Ontario and discovered a variety of litter, including fishing line, lures and packaging from fishing gear (e.g. worm containers, fishing gear packaging). Baits can be ingested by many different organisms (reviewed in Cooke and Cowx 2006) and lost line can become entangled in critters (Derraik 2002) and in addition has contributed to degradation of coral habitats (Yoshikawa and Asoh 2004). Fishing Gear loss really has the possibility to produce difficulties for a number of wildlife, but birds happen to be the focus of all studies. Soft plastic fishing lures (SPLs) have been commonly utilized in the angling community since the early 1970s. Soft plastic lures closely resemble natural forage and offer an alternate to live bait that is cumbersome. With growing concern for biosecurity and bait transport, there is certainly added recent interest in the utilization of SPLs to get a number of fisheries. Another advantage to the usage of SPLs is they are considerably stronger than live bait, permitting one to capture multiple fish per bait. This durability and longevity that is following is presumably a result of their being composed -biodegradable synthetic polymers. Currently, you will find numerous brands and types of soft plastic lures, and for the most part, they're the same general makeup, dampened plastic which includes 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.
