The suspended solid plumes can drift with the current for tens of kilometres from the source of the trawling, increasing sedimentation rates in deep environments [20] Bottom trawling-induced resuspended sediment mass on the world's continental shelves has been estimated at 22 gigatonnes per year, approximately the same as the sediment mass ...
Smell is also important, as indicated by the rapidity with which demersal fish find traps baited with bait fish. The main diet of deep sea demersal fish is invertebrates of the deep sea benthos and carrion. Smell, touch and lateral line sensitivities seem to be the main sensory devices for locating these. [3]

The VGP sets numeric ballast water discharge limits for large commercial vessels. The limits are expressed as the maximum acceptable concentration of living organisms per cubic meter of ballast water. [11] The Coast Guard worked with EPA in developing the scientific basis and the regulatory requirements in the VGP. [5]
Due to poor and often non-existent catch documentation by these vessels, the number of sea turtles and albatross caught by these vessels between 2000 and 2004 will never be known [citation needed]. Hawaii longline fishing for swordfish closed again on 17 March 2006, when the by-catch limit of 17 loggerhead turtles was reached.
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. [1] The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone .
