dc.description.abstract"Microplastics have plagued fish communities since the inception of industrialization and regulations have not been keeping pace. Microplastics are defined as particulates less than 5mm in size and are characterized by type (e.g., fragment, fiber, film, foam, bead, and nurdle/pellet), color, polymer, and size. Fish uptake particulates via ingestion, gill adhesion, and absorption. These microplastics have the potential to adsorb additional chemicals and toxins, further reducing reproduction, feeding, and survival. We conducted a survey of microplastics in fish of the Saranac River, New York using the traditional hook and line method to simulate common recreational angling practices. Fish were sampled above and below impoundments (e.g., Imperial Dam, Plattsburgh and Cadyville Dam, Cadyville, NY) and only fish that met New York state fishing regulations for capture were kept for microplastic analysis. Wet peroxide oxidation was used to isolate microplastics within digestive tracts and samples were then size separated (e.g., 1mm, 355um, 125um). Particulate was quantified and characterized under a dissecting microscope. Fish generally had higher microplastic burdens below impoundments, specifically 5.22 and 2.58 particles per gram in their stomachs and intestines, respectively. Fish captured above impoundments had 2.56 and 1.74 particles per gram in their stomach and intestines, respectively. The most prevalent particulate size was 125 microns, the smallest of size classes. Fibers were 97 and 99% prevalent above and below impoundments, respectively and were largely blue in color. With the traditional hook and line method becoming ever more popular in recent years, it is imperative that anglers understand the microplastic pollution risks associated with their catches and offers an opportunity for community efforts to reduce our dependencies on plastic.
