The use of “omics” in freshwater mussel conservation Ieva Roznere, The Ohio State University Full Abstract
Freshwater mussels are the most endangered group of animals in North America. A common conservation technique involves translocating mussels to different habitats or bringing them into captivity. However, this often results in increased mortality and slower growth and, despite the necessity, we know very little about freshwater mussel health. We use “omics” techniques, such as transcriptomics and metabolomics, to better understand the physiology of these animals and how they respond to stress. Transcriptomics is the study of transcripts, the subset of genes that are being expressed at a certain time period. Metabolomics is the study of metabolites, the intermediates and products of metabolism. Because gene expression and metabolite production are closely associated with environmental conditions, studying changes in these biological molecules is especially helpful in understanding how animals react to environmental stressors. |
Freshwater Mussel In Vitro Research Jacqualyn Halmbacher, The Ohio State University Full Abstract
Since 2002, the Columbus Zoo & Aquarium’s Freshwater Mussel Conservation and Research Facility has been dedicated to reintroducing mussel populations back into Ohio’s rivers. The success experienced by this facility has resulted in the release of tens of thousands of mussels in Ohio via propagation and reintroduction; receiving accolades such as “The North American Conservation Award” in 2011. Recently, the facility has experienced a significantly higher degree of success in propagating freshwater mussels by implementing a cell culture technique known as in vitro. The Columbus Zoo & Aquarium’s Freshwater Mussel Conservation and Research Facility is among a handful of institutions across the United States successfully transforming juvenile mussels with this innovative technique. In vitro offers an alternative: eliminating host fish from the equation. The protocol allows thousands of juveniles to be cultured in one petri dish. This presentation will give insight into the in vitro research conducted at the Columbus Zoo & Aquarium’s facility partnered with The Ohio State University and Ohio Division of Wildlife. |
Flexing Our Mussels, Part Deux – Freshwater Mussel Husbandry and Collaborative Conservation at the National Mississippi River Museum & Aquarium
Mikaela Foust, National Mississippi River Museum & Aquarium Full Abstract
The National Mississippi River Museum & Aquarium has made a commitment to help its partners to restore and interpret freshwater mussels, considered by many to be among the most threatened taxa in North America. Our live freshwater mussel display has been a great introduction for much of the public who do not otherwise get to see live mussel beds. We intend to describe the husbandry methods that have been successful or us. In addition, our collaborative partnerships have been instrumental in jumpstarting additional conservation work, opening the door to resources that would not have otherwise been available to us. Learn how our simple early collaboration efforts have led to big opportunities to do conservation and research. Our hope is that this presentation will inspire other facilities, both big and small, to start or expand their own mussel projects |

Citizen Science, ex‐situ, and in‐situ Unionid Mussel Conservation: Possibilities for Zoos and Aquariums
Barrett Christie, Maritime Aquarium Full Abstract
Unionid molluscs are the most endangered fauna in North America, at present we are losing species faster than their populations can even be assessed. Avenues for conservation action include a range of possibilities such as citizen science, rescue, and small‐scale propagation efforts. Aquarists, researchers, and even educators can utilize their skillsets in animal care, transport, aquaculture, field collection, or science communication to contribute to conservation activities or promote awareness of this unique and fascinating taxon. In one case study, a small aquarium in the western U.S. was able to survey over 10,000 animals, rescue another 3500 from drought, and evolve to propagating threatened species never before bred in captivity. An overview of the scope of freshwater mussel conservation programs from aquaria, zoos, museums, and their partners will show how a facility with any size budget and resources can work towards ensuring the survival the most imperiled animals on our continent. |
