Among above pool type fishpass is mostly common. This types fishpass consist of a series of pools installed to aid the fish to overcome natural or artificial obstacles during fish migration. Fish migration take place in all three directions such as upstream, downstream and laterally. The general principle of upstream fish passes facilities (called fish passes, fish ways or some times even fish ladders) is to attract fish that move up the river to a specific location in the river down stream of the obstruction so as ot induce them (actively) or even make them (passively) pass up stream by opening a water way (fish pass in the strict sense) or by trapping them in a tank and transferring them upstream.
