Map of Listed, Proposed, and Candidate Fish and Mussels in the UTRB
-
Map depicting the number of listed, proposed, and candidate fish and mussel species within each 12-digit HUC within the Upper Tennessee River Basin. Occurrences include extant and historical records. Areas within the UTRB boundary not shaded by a color in the key have no records of imperiled fish and mussel species occurrences.

NOAA, USGS and partners: Chesapeake Bay ‘dead zone’ to vary from average to slightly smaller
-
Scientists expect that this year’s mid-summer Chesapeake Bay hypoxic low-oxygen zone or “dead zone” – an area of low to no oxygen that can kill fish and aquatic life – will be approximately 1.58 cubic miles, about the volume of 2.3 million Olympic-size swimming pools. This is close to the long-term average as measured since 1950.

Plan for the Population Restoration and Conservation of Imperiled Freshwater Mollusks of the Cumberland Region
-
The goal of this Plan is to provide a framework for the restoration of freshwater mollusk resources and their ecological functions to appropriate reaches of the Cumberlandian Region through the reintroduction, augmentation (R/A) and controlled propagation of priority mollusks. The Plan prioritizes propagation and R/A activities for Region mollusks and provides guidelines for resource managers and recovery partners. The Plan is not a legal document and is not intended to replace or supersede published recovery plans for listed mollusks.

Population Performance Criteria to Evaluate Reintroduction and Recovery of Two Endangered Mussel Species, Epioblasma brevidens and Epioblasma capsaeformis
-
Genetic and demographic modeling of two endangered mussel species, Epioblasma brevidens and E. capsaeformis, in the Clinch River, U.S.A., was conducted to determine quantitative criteria to evaluate performance of extant and reintroduced populations. Reintroduction modelling indicated that the initial population size created during a 5 year build-up phase greatly affected final population size at 25 years, being similar to the population size at the end of the build-up phase, especially when population growth rate was low. Excluding age 0 individuals, age 1 juveniles or recruits on average comprised approximately 11% and 15% of a stable population of each species, respectively. Age-class distribution of a stable or growing population was characterized by multiple cohorts, including juvenile recruits, sub-adults, and adults. Because of current barriers to dispersal and the low dispersal capability of some mussel species, reintroductions will play a prominent role in restoring populations in the United States.
