Silver Carp Hypophthalmichthys molitrix have spread throughout the Mississippi River Basin. Specifically, in the Middle Mississippi River (MMR), Silver Carp are reproducing successfully. While research suggests Silver Carp require a large river to reproduce, recent findings reveal Silver Carp are using the associated tributaries during early life. However, the relative proportion that each tributary contributes to the overall population is not fully understood. Therefore, this study aimed to identify natal habitats of adult Silver Carp from the Middle Mississippi River using otolith trace element and stable isotope analysis. I analyzed forty-one young-of-year (YOY) Silver Carp from six different tributaries of the MMR to evaluate previously established correlations between otolith and water strontium: calcium ratios (Sr:Ca). My results support a previously documented strong relationship (r2 = 0.94) between otolith and water Sr:Ca and suggests core values can be used to determine natal origins of Silver Carp. Consequently, thirty-eight adult Silver Carp otoliths from the MMR were analyzed using this relationship. My results indicate the following: 21% of the sample originated from the MMR; 13% originated from the Big Muddy River; 8% originated from the MMR or Big Muddy River; 3% originated from the Big Muddy River or Illinois River; 5% originated from a tributary not including the Big Muddy River; 37% originated from the MMR or Illinois River; 3% originated from the MMR, Big Muddy River or Illinois River; 5% originated from the MMR or Missouri River; and 5% originated from the Upper Mississippi River, Illinois River or a tributary not including the Big Muddy River. Surprisingly, fish had natal origins from tributaries previously thought to not contribute to the adult MMR population. High concentrations of YOY Silver Carp have been documented in these tributaries in recent years. This may indicate that use of these tributaries during this life stage is a novel occurrence. If this is indeed a novel occurrence, there is a lag time until these YOY fish recruit to the adult population. Thus, this research and consistent YOY sampling should take place regularly to better understand how YOY densities translate to an overall population year class.

520 $a Common Carp Cyprinus carpio (Linnaeus, 1758) were introduced from Europe in the 1800s. Long Term Resource Monitoring element (LTRM) has been studying the fish communities of the Upper Mississippi River Basin for over twenty years at six study reaches (pool 4; Lake City, MN, pool 8; La Crosse, WI, pool 13; Bellevue, IA, pool 26; Alton, IL, La Grange pool of the Illinois River; Havana, IL and the open river reach; Cape Girardeau, MO). The goal of this project is to evaluate the Common Carp populations at the six study reaches by estimating the relative biomass, determining the dynamic rate functions (recruitment, growth and mortality) and calculating Spawning Potential Ratio (SPR) equations to estimate the effects of simulated harvest. Common Carp were the most abundant fish in each of the six study reaches since 1993 and reached ages greater than 50. Key differences were revealed among Common Carp population dynamics of the six LTRM study reaches. Essentially, Common Carp were smaller and grew slower in the LaGrange reach and Pool 26 reaches when compared to the three northern reaches and the open river reach. Being such a long lived (up to 57 years old) and abundant species (highest relative biomass in the Upper Mississippi River); a high recruitment year could have detrimental impacts to the entire ecosystem for several decades. Our results suggest Common Carp could be recruitment-overfished with moderate exploitation rates (as low as 15%) as an option to help control Common Carp populations in the Upper Mississippi River Basin.
