1.   The boat would then sail in a circle, dragging the net, until it returned to the point of departure.

3.   Immense nets were dragged across the fronts of nearby buildings to prevent broken glass from snapping off and being carried by the wind into the demolition site.

4.   Most halibut are caught commercially by trawlers, which drag nets in deeper waters, and by hook and line.

5.   Since most shrimp boats drag their nets for two hours or more, trapped turtles drown before the nets are hauled aboard.

6.   Some trawlers have moved from dragging nets along the ocean floor for groundfish to dragging for lobsters.

7.   Some, such as a male nicknamed Necklace, drag nets around for years before shaking them.

8.   The commercial boats often drag nets that are like vacuum cleaners, hang gillnets that are miles long, and set miles-long lines with thousands of hooks.
