Destructive or not?[edit]

  • I removed this text from the article:
    Dredging is not always so destructive.[citation needed] The dredge ploughs the sea bottom to a depth of a few inches, but this layer at the bottom of the sea is often turned over anyway by worms and other organisms which burrow, and can also be disturbed by large storms. Scallop beds can be exploited in sustainable ways, providing sufficient unexploited areas remain for male and female scallops to mix spawn. [citation needed]
  • Scallop dredging is NOT similar to the long slow overturn (bioturbation) cause by worms etc. Scallop dredging turns the seabed upside down and inside out and ruins the grazing for the area's bottom-feeding sea life. Try scuba diving the same area before and after a scallop dredger has operated there. Anthony Appleyard (talk) 05:38, 21 August 2009 (UTC)
