“…Seasonal shifts in faunal abundance, diversity, and size, as observed here, are common in temperate marine ecosystems, including the North Inlet estuary (Kimball et al, 2023). Among other causes, these seasonal patterns can be due to migration (Akin et al, 2003), recruitment of juveniles into nursery habitats (Shervette & Gelwick, 2008), or predatory impacts (Beseres Pollack et al, 2009).…”

Despite the popularity of recreational fishing, our understanding of the impacts of this type of harvest within marine ecosystems generally lags behind the well‐documented effects of commercial fisheries. Intertidal oysters serve as ecosystem engineers within otherwise soft‐bottom estuaries but may be disproportionately susceptible to harvest because of their sessile nature and accessibility at low tide. We used a Before–After–Control–Impact design to investigate the effects of recreational oyster “picking” on the physical structure provided by reefs and the community of reef‐associated mobile fauna. Despite reductions in oyster density on harvested reefs following the fishing season, we did not observe changes in other biophysical properties of reefs. Similarly, we found variable impacts of oyster harvest on the community of reef‐associated fauna, with community diversity changing seasonally on closed reefs but remaining low throughout on harvested reefs. Direct relationships between change in oyster density through time and changes in reef rugosity, faunal diversity, and faunal density were also variable. While oyster harvest removes the physical structure provided by these foundation species, the level of recreational harvest currently occurring in our study system apparently does not exceed the threshold which leads to cascading changes in reef‐associated fauna.

“…Bilkovic and Roggero [39] found analogous results in Virginia's James River, a tidal tributary of the Chesapeake Bay, where estuarine communities populating natural shoreline habitat tended to be more diverse than highly developed sites where a few generalist species dominated. Kimball and co-workers [40] worked over a similar decadal time span but evaluated different metrics. They saw a decrease in ichthyofaunal abundance and a shift from pelagic to benthic finfish dominance.…”

Natural environmental change, anthropogenic development, and inter-annual variability can affect the ecology of estuarine fish and invertebrates. Yaquina Bay, Oregon, a well-studied estuary, has undergone intense development, as well as deep-draft dredging during the latter half of the 20th century, resulting in the alteration of ~45% of the lower estuary’s natural shoreline. In 1967, the United States Environmental Protection Agency (USEPA) conducted a 21-month survey of Yaquina Bay to characterize the demersal fishes and epibenthic crustaceans that occupy the bay. From 2003 to 2005, we conducted a 25-month survey to replicate that work and provide a comparative snapshot of the demersal fish and epibenthic crustacean community in the bay. A comparison of the trawl survey datasets reveals a 91% decline in total catch per unit effort (CPUE) between surveys, as well as a decline in multiple measures of biodiversity. Furthermore, the fishes and crustaceans of Yaquina Bay have experienced a shift in species dominance from demersal fishes in the late 1960s to epibenthic crustaceans in the 2000s, marked most notably by a nine-fold increase in the Dungeness crab CPUE. While this work does not establish a causal relationship between changes in the demersal communities of this West Coast estuary and human or natural events, it does document substantial changes in both the diversity and total abundance of animals in that community over a three-plus decade period of development and environmental variability. Hence, this forms a second baseline for continued long-term monitoring.
