TL;DR: It appears that communities from hydrodynamic fishing grounds that are well adapted to natural physical stress are not highly affected by dredging, and at shallower depths communities demonstrated a faster recovery.

TL;DR: It is suggested that dredging projects may only cause short-term positive effects on lake ecosystem health, and should be combined with other ecological lake restoration measures when the project has caused positive effects in a lake.

TL;DR: In this paper, the effects of dredging and associated development pressures (e.g., shoreline armoring, developed land use) on fish were investigated in three sets of paired dredged and undredged tidal creeks.
Abstract: To investigate the effects of dredging and associated development pressures (ie, shoreline armoring, developed land use) on fish, three sets of paired dredged and undredged tidal creeks were surveyed within Lynnhaven River, Virginia Fish species diversity, community abundance, biomass, and size structure were compared among creeks and related to watershed, shoreline, and physicochemical characteristics Mean fish community characteristics (eg, abundance) were similar among creeks; however, species-specific analysis revealed subtle differences Species biomass differed between dredged and undredged creeks, though species abundance was similar Turbidity highly influenced differences in species abundance among creeks, while organic matter, dissolved oxygen, turbidity, and shoreline hardening may be influencing biomass patterns The most recently dredged creek appeared to provide less suitable nursery habitat for some species than historically dredged creeks, suggesting initial adverse effects with eventual recovery Protective measures, such as preservation of marshes, dredge depth, and time-of-year restrictions, may be moderating development and dredging pressures

TL;DR: In this article, the authors examined whether suction dredging for cockles on tidal flats of the Dutch Wadden Sea had affected densities of non-target fauna, directly after fishing and one year later.

TL;DR: In this paper, the authors used the information contained in the Italian Ministry of the Environment Acts related to dredging of Carrara Harbor determined the sediment volume dredged between 1993 and 2008 (849,500 m3) and allowed us to estimate an average rate of material dredged from the harbor mouth (10,000-13,000 m3/yr).
