Development of tools to assess genetic and age structuring of the Atlantic Sea Cucumber (Cucumaria frondosa)

As fisheries for the Atlantic Sea Cucumber (Cucumaria frondosa) develop in Atlantic Canada, effective management will require a thorough understanding of the underlying genetic relationships within and between different populations to assess “genetic health.” Detecting genetic structure, such as differences in allelic frequencies and heterozygosity, is challenging in marine invertebrate species like C. frondosa due to having a highly dispersive and long larval stage, which results in high levels of gene flow between populations.
