Threats to Habitat

Bottom Disturbing Fishing Gear

Habitats Affected: Shell bottom, SAV, soft bottom, ocean hard bottom, water column

Common Sources:See Table Below

Impacts

  • Mobile bottom disturbing gears dig down into the bottom and uproot SAV.
  • Hard bottom and shell bottom structure can be broken apart, killing organisms and reducing habitat value.
  • The vertical profile of subtidal oyster reefs can be lowered, making the shell bottom community more susceptible to low oxygen events.
  • Elevated turbidity can degrade water column, SAV, shell botttom, or hard bottom habitat, depending on the frequency and intensity.
  • Disturbance of soft bottom habitat can alter productivity of benthic microalgae and reduce structural complexity of the bottom.
