How to construct a net hapa?
A nylon thread is used to sew the net hapa into its required size and shape. This is done by using a sewing machine. Kuralon rope is passed through nylon cloth tape on the vertical corners of the hapa. This is done to fortify the hapa. The Kuralon rope is made in such a way that it extends out of the four corners of the hapa in the form of loops. To these loops, the riggers are tied which helps the hapa to float in the water for fish culture or breeding.
