River fish trap

A bamboo fish trap is placed at a rapid in the river where fish flow in. The mouth of the trap is made in such a way that fish cannot swim back out. Traps used to be a common method of river fishery in land-locked Nepal, but lately a decline in the number of fish species as well as the amount of fish in the rivers, attributed to human activities such as dam building and use of pesticides, has caused a decrease in trap-use and fishing in general.
