“…The majority of shells planted in Virginia waters in recent years have been dredged shells, with shucking house shells comprising a smaller portion [∼500,000 bushels (22,600 m 3 )/year]. Most of this shucking house shell was not derived from local harvests but from imported shell stock from the Gulf of Mexico, as the few remaining (161 in 1981, 36 in 2009) oyster shucking and packing houses in Virginia primarily imported and processed live oysters from the Gulf of Mexico until the Deepwater Horizon oil spill in 2010 impacted a significant part of the gulf oyster fishery, causing a wide-scale closure of most of it (Sumaila et al, 2012) and the increasing local harvests in recent years.…”

Oyster populations in Virginia's waters of Chesapeake Bay were lightly exploited until the early 1800s, when industrial fishery vessels first arrived, driven south from New England due to the collapse of northeastern oyster fisheries. Early signs of overexploitation and habitat degradation were evident by the 1850s. The public fishery, where oyster fishers harvest on state-owned bottom, rapidly developed after the Civil War and peaked in the early 1880s. Declines were noted by the late 1880s and eventually prompted the creation of Virginia's shell-planting and oyster-seed (young-of-the-year, YOY) moving repletion program in the 1920s. Despite management and increasing repletion efforts, the public fishery collapsed (annual landings <10% of peak historical landings) by the early 1960s. The private leasehold fishery, in which individuals rent areas outside the public grounds to plant shells and oysters for their own private use, surpassed the public fishery by the late 1920s, which partly masked this decline due to overfishing, habitat degradation, and diseases until both public and private fisheries completely collapsed in the mid-1980s after a third disease outbreak. This disease outbreak was likely related to warming waters. Overfishing and concomitant habitat loss followed a pattern of sequential population collapses observed in wild oyster fisheries along the Coastlines of the United States and worldwide. In recent years, expanding hatchery-produced seed oysters and aquaculture significantly increased leasehold landings. The wild fishery has also increased as disease resistance is developing naturally in the wild stocks, but remains ∼5% of peak landings. Improved management has assisted in this recent limited recovery, improving these efforts further by enhancing stock recovery via large no-take sanctuaries, among other actions, could assist in stock recovery.

“…Volatile organic compounds (VOCs), such as hexane, benzene, toluene, ethylbenzene, and xylenes (BTEX), are a large fraction of petroleum hydrocarbons, representing up to 15% of all hydrocarbon contaminants (2). These compounds can have a broad range of toxicity on a large number of organisms (3), affecting natural biota and ecosystems (4), fisheries (5), and human health (6). Although the most dramatic effects usually are observed when a large volume of oil is spilled, it also has been shown that small quantities of oil can severely impact marine ecosystems (7).…”

cHydrocarbons released during oil spills are persistent in marine sediments due to the absence of suitable electron acceptors below the oxic zone. Here, we investigated an alternative bioremediation strategy to remove toluene, a model monoaromatic hydrocarbon, using a bioanode. Bioelectrochemical reactors were inoculated with sediment collected from a hydrocarbon-contaminated marine site, and anodes were polarized at 0 mV and ؉300 mV (versus an Ag/AgCl [3 M KCl] reference electrode). The degradation of toluene was directly linked to current generation of up to 301 mA m ؊2 and 431 mA m ؊2 for the bioanodes polarized at 0 mV and ؉300 mV, respectively. Peak currents decreased over time even after periodic spiking with toluene. The monitoring of sulfate concentrations during bioelectrochemical experiments suggested that sulfur metabolism was involved in toluene degradation at bioanodes. 16S rRNA gene-based Illumina sequencing of the bulk anolyte and anode samples revealed enrichment with electrocatalytically active microorganisms, toluene degraders, and sulfate-reducing microorganisms. Quantitative PCR targeting the ␣-subunit of the dissimilatory sulfite reductase (encoded by dsrA) and the ␣-subunit of the benzylsuccinate synthase (encoded by bssA) confirmed these findings. In particular, members of the family Desulfobulbaceae were enriched concomitantly with current production and toluene degradation. Based on these observations, we propose two mechanisms for bioelectrochemical toluene degradation: (i) direct electron transfer to the anode and/or (ii) sulfide-mediated electron transfer.

“…Although some of the environmental impacts were obvious (contaminated shorelines and mortality of marine mammals and birds), the longer-term and sublethal impacts that may persist in marine fish species of the GOM are less apparent (Bue et al 1998;Sumaila et al 2012). Some long-term impacts can be relatively easy to detect (e.g., bioaccumulation of hydrocarbons), but others (e.g., community changes, trophic shifts, or year-class failures) are subtle and difficult to detect against normal background environmental and ecological variability.…”

The Deepwater Horizon oil spill was one of the largest oil spills in U.S. history. The timing of this spill coincided with peaks in spawning and recruitment of Red Snapper Lutjanus campechanus and may have led to reduced recruitment or to year‐class failure. Artificial recruitment reefs were deployed in 2010 (n = 30) and 2011 (n = 30) to measure Red Snapper recruitment off the coast of Alabama at four sites (three inshore sites, 13 km south: west, center, and east sites, each 30 km apart; and one offshore site, 25 km south). Substantial age‐0 Red Snapper recruitment (density range = 0–34.5 fish/m3) occurred in 2010, with higher densities on inshore reefs than on offshore reefs. Age‐0 Red Snapper recruitment was again observed in 2011 (density range = 0–108.5 fish/m3) along with age‐1 Red Snapper (density range = 0–78.9 fish/m3) from the 2010 year‐class. There was a negative correlation between the densities of age‐0 and age‐1 Red Snapper, indicating that older Red Snapper excluded younger fish from the reefs. Higher fractions of silt in the substrate at the west site compared with the center and east sites were associated with higher densities of age‐0 Red Snapper, but the effects of sediment type were less important than exposure to hypoxic conditions at the west site in late August 2011 (dissolved oxygen fell to concentrations as low as 0.4 mg/L), which caused an almost complete loss of fish. The abundances of age‐0 and age‐1 Red Snapper in 2010 and 2011 provide evidence that the oil spill did not result in a year‐class failure and that the most important variables affecting age‐0 Red Snapper abundances were age‐1 Red Snapper presence and dissolved oxygen concentration.
