They pour cement in the bottom of the crab traps so they will land bottom first once set off the boat. This way they will fish properly. Very few lobstermen pour cement in the bottom of lobster traps but I have seen it here and there. The prefered method of weighting a lobster trap is with bricks. This is another difference between lobster traps and crab traps.
