Assessing Biodiversity at Eastern Oyster (<i>Crassostrea virginica</i>) Aquaculture and Reef Sites Utilizing Real-Time Monitoring and Environmental DNA in Rehoboth Bay, Delaware, USA. [PDF]

open access: yesEcol Evol
Eastern oysters (Crassostrea virginica) are a keystone species and vital to the commercial shellfish industry, acting as environmental engineers that enhance biodiversity. To study their impact, real‐time monitoring and Environmental DNA analysis were conducted at various sites in Rehoboth Bay, Delaware and 23 species were identified, with Spot ...

Epigenetic Responses to Anthropogenic Versus Natural Sources of Oil Exposure Differ in Wild Arctic Seabird Populations. [PDF]

open access: yesEvol Appl
ABSTRACT Anthropogenic pollution can have detrimental effects on organismal physiology, behavior, and fitness, but the underlying genomic mechanisms mediating these effects are not well understood. Epigenetic regulation, such as DNA methylation, has been proposed as a potential mechanism mediating these effects, but currently, there are few studies in ...

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids

open access: yesEcosphere, Volume 14, Issue 12, December 2023., 2023
Abstract Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon (Salmo salar) experience lower predation than Sea trout (Salmo trutta), yet telemetry studies ...

Waiting for the right time and tide: The fine‐scale migratory behavior of river herring in two coastal New England streams

open access: yesMarine and Coastal Fisheries, Volume 15, Issue 5, October 2023., 2023
Abstract Objective Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis, collectively referred to as river herring, are anadromous clupeids inhabiting the North American Atlantic coast. Although the seasonal patterns of their spawning migration are well studied and predictable, the fine‐scale movements are still poorly resolved. Methods This

Great cormorant (Phalacrocorax carbo sinensis) predation on adult anadromous brown trout (Salmo trutta)

open access: yesEcology of Freshwater Fish, Volume 32, Issue 2, Page 488-495, April 2023., 2023
Abstract The increase in abundance of great cormorants (Phalacrocorax carbo sinensis) over the last decades has caused concern for the sustainability of fish populations. Cormorants are opportunistic piscivorous birds that eat fish from a wide range of species and sizes, in marine, lacustrine and riverine habitats.

Cost of regulations on US catfish farms

open access: yesJournal of the World Aquaculture Society, Volume 54, Issue 1, Page 32-53, February 2023., 2023
Abstract Understanding the economic effects of regulations on US aquaculture farms provides insights into which compliance costs create the greatest compliance burden on farms. This can further guide strategies to improve the efficiency of regulatory frameworks and potentially reduce on‐farm compliance costs while maintaining adequate oversight.

Effects of Aquaculture on Migration and Movement Patterns of Double-Crested Cormorants

open access: yesHuman-Wildlife Interactions, 2017
We analyzed 10,620 recovery records for double-crested cormorants (Phalacrocorax auritus) banded as nestlings from 1923 to 2006 to determine the population’s age structure, migration routes, dispersal patterns, and the possible influence of the expansion
