Book excerpt: The introduction and spread of two Asian Carp species, Bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix have caused severe ecological damage throughout North America. Currently, academic institutions, and state and federal agencies are investigating ways of controlling the spread of these species and managing existing populations to minimize further damage. One promising method of control is the commercial harvest of Asian carps for export to China, as both species are highly valued foodfish throughout Asia. Habitat modification and destruction, along with the questionable quality of fish produced in aquaculture facilities throughout China, have caused members of the foodfish industry to search elsewhere for a high quality product destined for middle and upper class consumers in China. At this time, harvest practices are not standardized, and taking market potential into consideration, it is important to optimize aspects of harvest so commercial fishermen and processors can supply consumers with the highest quality product. Therefore, the present studies evaluated the effects of season, geographic origin, and harvest gear on commercially caught fresh fish and those subjected to standard processing practices and simulated shipping conditions to China using quality evaluation methods common in the foodfish industry. Information assembled in this research can be used by commercial fishermen and processors to develop standardized methods for the harvest of Asian carps. Providing a high quality product is vital considering market potential and the resulting economic stimulation provided to fiscally starved areas where these facilities are located. Most importantly, the development of this industry could, in conjunction with continued academic and agency efforts, offer an independent solution to the serious ecological threat posed by these species.

This book was released on 2014 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsidized harvest of invasive silver carp Hypopthalmichthys molitrix and bighead carp H. nobilis (collectively referred to as Asian carp) from the Illinois River have been initiated in an effort to control their populations. However, market-driven control strategies have been suggested in an effort to reduce or eliminate the need for subsidies. Given that Asian carp are not a favored food fish in the U.S. and exporting to Asian markets is currently not economically feasible, industrial applications such as fish meal production have been explored. Fish meal production to support aquafeed manufacturing is potentially a high-value, high-volume market which is essential to a market-driven approach. However, the nutrient composition of Asian carp as a raw material from the Illinois River needs to be evaluated as well as the nutrient digestibility and production performance of a rendered Asian carp fish meal product to fully assess its suitability for use in aquafeeds. To determine the suitability of Asian carp to support aquafeed manufacturing, we evaluated seasonal and geographical differences in Asian carp harvested from the Illinois River, performed standard digestibility trials with hybrid striped bass and rainbow trout, and assessed production performance through standard feeding trials with hybrid striped bass, rainbow trout, and cobia. Results indicate slight geographical and seasonal variation in body composition, though both species represent protein-dense raw materials suitable for fish meal production. Additionally, Asian carp fish meal is a highly digestible feedstuff that closely resembles the nutrient content of traditional menhaden fish meal sources, although it is slightly less digestible. Production performance of fish fed practical Asian carp fish meal based diets was similar to those that used menhaden fish meal. Overall, Asian carp fish meal appears to be a highly-digestible, nutrient-dense ingredient suitable for inclusion in aquafeeds. Therefore, rendering Asian carp into fish meal appears to be a viable market-driven approach to help control Asian carp populations.

Available in PDF, EPUB and Kindle. Book excerpt: Four species of non-indigenous Asian carp are expanding their range in U.S. waterways, resulting in a variety of concerns and problems. Three species—bighead, silver, and black carp—are of particular note, based on the perceived degree of environmental concern. Current controversy relates to what measures might be necessary and sufficient to prevent movement of Asian carp from the Mississippi River drainage into the Great Lakes through the Chicago Area Waterway System. Several bills have been introduced in the 112th Congress to direct actions to avoid the possibility of carp becoming established in the Great Lakes. According to the Great Lakes Fishery Commission, Asian carp pose a significant threat to commercial and recreational fisheries of the Great Lakes. Asian carp populations could expand rapidly and change the composition of Great Lakes ecosystems. Native species could be harmed because Asian carp are likely to compete with them for food and modify their habitat. It has been widely reported that Great Lakes fisheries generate economic activity of approximately $7 billion annually. Although Asian carp introduction is likely to modify Great Lakes ecosystems and cause harm to fisheries, studies forecasting the extent of potential harm are not available. Therefore, it is not possible to provide estimates of potential changes in the regional economy or economic value (social welfare) by lake, species, or fishery. The locks and waterways of the Chicago Area Waterway System (CAWS) have been a focal point for those debating how to prevent Asian carp encroachment on the Great Lakes. The CAWS is the only navigable link between the Great Lakes and the Mississippi River, and many note the potential of these waterways to facilitate invasive species transfers from one basin to the other. The U.S. Army Corps of Engineers constructed and is currently operating electrical barriers to prevent fish passage through these waterways. In light of recent indications that Asian carp may be present upstream of the barriers, increased federal funding to prevent fish encroachment was announced by the Obama Administration. Part of this funding is being spent by the Corps of Engineers to explore options relating to the “hydrologic separation” of the Great Lakes and Mississippi River drainage basins. The potential closure of navigation structures in the CAWS is of particular interest to both the Chicago area shipping industry and Great Lakes fishery interests. Since December 2010, Michigan and other Great Lakes states have filed a number of requests for court ordered measures to stop the migration of invasive Asian carp toward Lake Michigan from the Mississippi River basin via the CAWS. The U.S. Supreme Court denied several motions for injunctions to force Illinois, the U.S. Army Corps of Engineers, and the Metropolitan Water Reclamation District of Greater Chicago to take necessary measures to prevent the carp from entering Lake Michigan. Michigan, Minnesota, Ohio, Pennsylvania, and Wisconsin sought a separate order in federal district court seeking similar relief, which was also denied. In the 112th Congress, language in P.L. 112-74 authorized the Corps of Engineers to take emergency measures to exclude Asian carp from the Great Lakes. In addition, H.R. 892 and S. 471 would direct federal agencies to take measures to control the spread of Asian carp. Notably, each of these bills, as well as H.R. 4406 and S. 2317, would require the Corps of Engineers to complete the Chicago portion of a study on hydrologic separation of the Great Lakes and Mississippi River Basin within 18 months of enactment. H.R. 2432 would require the Corps of Engineers to prepare an economic impact statement before carrying out any federal action relating to the Chicago Area Water System. H.R. 4146 and S. 2164 would authorize the Corps of Engineers to take actions to manage Asian carp traveling up the Mississippi River in Minnesota.

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asian carp have rapidly expanded their range through much of the Mississippi River drainage over the past 10 to 15 years. Silver and bighead carp are now the dominant fish species present along several reaches of the Illinois River. The upper Illinois River and shipping canals entering Lake Michigan are of great concern as pathways for Asian carp to enter the Great Lakes. Knowledge of reproductive habitats and dispersal pathways for these species may be valuable for ongoing and future efforts to control these exotic invasives. Previous studies have successfully identified spawning areas of native riverine species via otolith microchemistry, but this technique has not yet been applied to Asian carps. Both stable isotope and trace element ratios have been found to differ significantly among the large rivers of the Mississippi River drainage, enabling identification of natal environment for individual fish. The primary objective of this study was to identify differences in natal river origin and floodplain habitat use through the incorporation of trace elements (Sr:Ca) and stable isotopes. Silver and bighead carp were collected via electrofishing and trammel netting along four reaches of the Illinois River from the Mississippi-Illinois River confluence at Grafton, IL to the upper segment of the Illinois River upstream of Starved Rock State Park. Sagittal otoliths were removed from both silver and bighead carp collected from each of the four reaches of the Illinois River for analysis of stable isotope ratios and trace element concentrations. Water samples were collected seasonally from the four reaches of the Illinois River and several of its associated floodplain lakes in addition to the Missouri, Upper Mississippi and Middle Mississippi Rivers to validate water signatures of the various river reaches. Results indicated the majority of adult Asian carp caught in the Illinois River originated from the Illinois. However, there was strong evidence indicating roughly twenty percent of captured adults were in fact immigrants from other sources; primarily the Middle Mississippi river and, to a lesser extent, the Missouri River. Stable isotope results indicated that Asian carps primarily used river channel rather than floodplain lake habitats during early life. The findings of this study suggest current Asian carp removal efforts should continue to be primarily directed within the Illinois River, however, the evidence of immigrant silver carp indicate expanding the control efforts into other rivers (Middle Mississippi River and Missouri River) will further support the control of Asian carp within the Illinois River.

Book excerpt: Intelligent investigative writing meets experiential journalism in this important look at one of North America’s most voraciously invasive species Politicians, ecologists, and government wildlife officials are fighting a desperate rearguard action to halt the onward reach of Asian Carp, four troublesome fish now within a handful of miles from entering Lake Michigan. From aquaculture farms in Arkansas to the bayous of Louisiana; from marshlands in Indiana to labs in Minnesota; and from the Illinois River to the streets of Chicago where the last line of defense has been laid to keep Asian carp from reaching the Great Lakes, Overrun takes us on a firsthand journey into the heart of a crisis. Along the way, environmental journalist Andrew Reeves discovers that saving the Great Lakes is only half the challenge. The other is a radical scientific and political shift to rethink how we can bring back our degraded and ignored rivers and waterways and reconsider how we create equilibrium in a shrinking world. With writing that is both urgent and wildly entertaining, Andrew Reeves traces the carp’s explosive spread throughout North America from an unknown import meant to tackle invasive water weeds to a continental scourge that bulldozes through everything in its path.

Available in PDF, EPUB and Kindle. Book excerpt: Bureaucratic Impediments to Collaboration: A Case Study of the Asian Carp and the Great Lakes Basin Christina Wille Chair of the Supervisory Committee: Professor Thomas Leschine School of Marine and Environmental Affairs Silver carp and bighead carp, also known as Asian carp, were first imported to the United States in the early 1970s for use in aquaculture, research, and waste management; however, these species escaped to the Mississippi River basin in various flooding incidents by 1980s. Both species have now spread throughout much of the upper Mississippi River system. In the Illinois River, commercial fishing operations harvested over 5 million pounds of bighead and silver carp from the Illinois River in 2009. Depending on its life stage, Asian carp will eat between 5-20% of its body weight daily in plankton, and adult Asian carp can weigh more than 25 kg. Almost all native fish in the Great Lakes Basin depend on plankton for at least part of their life cycle, so an established population of Asian carp will have profound effects on the ecosystem. Moreover, the presence of silver carp in a waterway poses a serious risk to boaters, since these fish have excellent hearing and leap 8-10 feet into the air when startled and have caused bruises, concussions, and broken bones when the carp have collided with humans. Natural resource managers are concerned about the possible introduction of bighead and silver carp to the Great Lakes Basin through the Chicago Area Waterways System. In response to the potential introduction of Asian carp species to the Great Lakes, the Obama Administration formalized the Asian Carp Regional Coordinating Committee (ACRCC) in 2010. This thesis studies the relationship between the organizational structure of the ACRCC's member agencies and these agencies' efforts to work together. One hypothesis is that agencies key to ACRCC efforts exhibit fewer characteristics of a bureaucratic organization; an alternate hypothesis is that the agency's calculation of the costs of and benefits resulting from collaboration explain its decision to collaborate or not. Data was gathered through elite interviews with agency representatives who attend ACRCC meetings. Interview questions were designed to gather insights into several different aspects of the agencies involved and the ACRCC in general, including the structure of each participant's agency, the participant's agency's role in the ACRCC as well as the roles that other important agencies play in the ACRCC, and the effectiveness of the ACRCC as an organization, together with any factors that aid or detract from the ACRCC's goal. The questions were designed to be general, to allow each participant's perceptions of the ACRCC to guide our discussion. The open nature of the questions and the resulting responses led to the creation of the second hypothesis midway through the interviews. Data supported both hypotheses: some correlation was found between the levels of collaboration and the levels of bureaucratic characteristics as predicted by the first hypothesis, especially in federal agencies. There was also support for the second hypothesis, particularly for state agencies. These costs and benefits included jurisdictional issues and access to resources (whether these aspects were considered costs or benefits depended on the circumstances organizations were faced with), as well as concerns about the costs associated with the continued spread of Asian carp. However, given the limits of this study it is not possible to conclusively prove one hypothesis over the other. Interview responses also provided information about the level of collaboration for the ACRCC as a whole. The organization provides a forum for communication about the issue among its members, but the ACRCC does not yet appear to rise consistently to the level of true coordination. Due to the limitations of this study, it is not possible to make predictions about future collaborative efforts in the ACRCC. Further studies are necessary to gather more information before such predictions can be reliably made.

Available in PDF, EPUB and Kindle. Book excerpt: 1st Chapter: Controlling invasive fishes is a pressing issue in fisheries management. Commercial harvest and bounty programs are often used as a control method to reduce abundance and lessen the destructive impacts of an invasive species. One group of species that may be controlled with harvest are invasive carps [Black Carp (Mylopharyngodon piceus), Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix)]. To reduce source populations and propagule pressure of invasive carps near the Laurentian Great Lakes, an enhanced contract commercial fishing program was started on the Peoria Pool of the Illinois River in September 2019. Commercial fishers received compensation of $0.10 for every pound of invasive carps caught in the Peoria Pool of the Illinois River on top of the price they were paid at the fish processing plant. My thesis used mobile hydroacoustic sampling to evaluate the effects of the enhanced contract fishing program by evaluating changes in invasive carp densities, biomass, and size structure from February 2020 to August 2021. The enhanced contract fishing program did increase fishing effort in the Peoria Pool of the Illinois River, which in turn increased harvest from 1,284,931 kgs of invasive carp in 2020 to 1,515,575 kgs of invasive carp in 2021. The average of hydroacoustic densities was 1.19 kgs/1000m3 and there was not a significant change throughout the duration of the project. It will be important to continue evaluating the enhanced contract fishing program as commercial fishing programs can take years to have effects. This study serves as a unique case study for future management by allowing us to assess how bigheaded carp abundances change due to commercial fishing pressure. 2nd Chapter: Understanding the effects and having accurate estimates of demographic rates of an invasive species is important for management. Commercial harvest/removal is a common method of invasive species management. Quantifying mortality rates can be useful in informing population models for future management decisions for Silver Carp removal efforts. The objective of this study was to compare Silver Carp total annual mortality between the Wabash and Illinois Rivers, where additive mortality due to fishing and other factors likely differs. With the necessity of increasing additive mortality to bring down populations, these estimates are important to more accurately parameterize future control models as well as to differentiate between rivers with different management methods and other sources of mortality. For this study, survival and detection probabilities were determined in Program MARK using a Cormack-Jolly-Seber Models of acoustically tagged Silver Carp over 8 years and were compared between the upper and lower Illinois River and the Wabash River. The survival estimate for Silver Carp in the Wabash River (0.97±0.02) was higher than those in the Illinois River (0.22±0.14 to 0.77±0.07). Harvest and perhaps commercial barge traffic are leading to higher mortality in the Illinois River as there was much higher harvest and mortality in the Illinois River than there was in the Wabash River. Higher overall mortality in the Illinois River appears to be affecting densities differently in the upper and lower river due to the differing harvest strategies in these stretches of river. Previous estimates of annual mortality for the Illinois River were similar to our estimates. The Wabash River Silver Carp mortality was much lower than previous published estimates. This study serves as a unique method for evaluating the impacts of large-scale removal efforts and may also be useful in informing the Spatially Explicit Invasive Carp Population (SEICarP) modeling effort on how best to develop future management actions and harvest efforts.

This book was released on 2014-03-30 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of molecular methods, such as the detection of environmental deoxyribonucleic acid (eDNA), have become an increasingly popular tool in surveillance programs that monitor for the presence of invasive species in aquatic systems. One early application of these methods in aquatic systems was surveillance for DNA of Asian carps (specifically bighead carp Hypophthalmichthys nobilis and silver carp H. molitrix) in water samples taken from the Chicago Area Waterway System (CAWS; Jerde et al. 2011). Analysis of water samples from the CAWS to detect DNA of Asian carps has since been integrated into the Asian carp monitoring program managed by the Monitoring and Response Work Group, an interagency group established by the Asian Carp Regional Coordinating Committee. The U.S. Army Corps of Engineers (USACE) is presently responsible for the analysis of DNA in samples taken from the CAWS and has led the development and refinement of the methods and procedures used to process environmental samples to detect Asian carp DNA. Those methods are specified within the USACE “Quality Assurance Project Plan” or QAPP (USACE 2012).
