In-Vitro Propagation And Fish Assessments To Inform Restoration Of Dwarf Wedgemussel (Alasmidonta Heterodon), Jennifer Ryan
In-Vitro Propagation And Fish Assessments To Inform Restoration Of Dwarf Wedgemussel (Alasmidonta Heterodon), Jennifer Ryan
Masters Theses
The dwarf wedgemussel (Alasmidonta heterodon) is a federally endangered freshwater mussel that once ranged from New Brunswick to North Carolina, but now only exists in isolated populations throughout its diminished range. Laboratory propagation in conjunction with augmentation or reintroduction is considered a critical component of dwarf wedgemussel restoration. My thesis aimed to I) develop in-vitro propagation techniques including methods to minimize microbial contamination for two Alasmidonta species and II) compile and assess critical fish assemblage information at existing dwarf wedgemussel presence and absence locations to inform future restoration activities. For the first objective (Chapter 2) I assessed three …
New England’S Underutilized Seafood Species: Defining And Exploring Marketplace Potential In A Changing Climate, Amanda Davis
New England’S Underutilized Seafood Species: Defining And Exploring Marketplace Potential In A Changing Climate, Amanda Davis
Masters Theses
New England’s seafood industry has been searching for opportunities to diversify their landings and build resilience as it faces socio-economic challenges from a changing climate. Developing markets for underutilized species is one way the New England community could help their seafood industry build resilience. This thesis identified New England’s underutilized fish species and explored their marketplace potential by examining their availability in a changing climate, current availability to consumers, and consumers’ responses. In Chapter I, I account how New England’s seafood preferences have changed over time. In Chapter II, I identify New England’s seven underutilized seafood species: 1) Acadian redfish …
Improving Growth And Survival Of Cultured Yellow Lampmussel (Lampsilis Cariosa) For Restoring Populations, Virginia Martell
Improving Growth And Survival Of Cultured Yellow Lampmussel (Lampsilis Cariosa) For Restoring Populations, Virginia Martell
Masters Theses
In North America 72% of freshwater mussel species are endangered, threatened, or of special concern due to factors such as habitat loss and degradation, biological invasion, and land use change. Propagation of freshwater mussels has been considered a necessary conservation strategy for population restoration where threats have been mitigated but small population sizes limit population viability. Yellow lampmussel is a species of freshwater mussel that is endangered, threatened, or imperiled throughout its range; therefore, I evaluated laboratory techniques (probiotic supplements and secondary rearing designs) to improve culture of yellow lampmussel for population restoration. Several aquaculture facilities commonly use probiotics; thus, …
