Many of these are mainly made up of bamboo at Mendha and from synthetic material at Khursa. Following types of indigenous fishing instruments has been documented from both villages,
Dhiri
Reported from Mendha, this is a rectangular trap of bamboo sticks (Locally called Kaduhu) interwoven by nylon threads (Initially instead of nylon threads fiber made up of Boyal tree were in use). This is a passive method of fishing. Virtually this trap operate on a ‘funnel’ or ‘maze’ principle, with fish passing easily through an entrance hole, but being confused by the blind endings within the trap and being unable to find their way out. The dimensions of box vary as per need, but standard size is 2.5 feet (0.76 m) to 5 feet (1.5 m) long, 0.5 to 1 foot (0.30 m) wide and 1 to 1.5 feet (0.46 m) high. This structure has 2 to 3 doors on both sides. The entrances or doors are very specialized structures, work as one-way valves, due to this valve fish can enter inside but cannot escape. The diameter of the doors is 2.5 cm wide, so that fish of this much of size can only be caught. Dhiri set in running water generally in night. The setting of the Dhiri is laborious work and needs about 1 hour time. This can only set in at least 0.5 feet (0.15 m) deep water (so that water level should be slightly above the door) with the help of rope, mud and branches of the trees. Fishes moving along with stream of water enters into the doors. About 1 kg to as much as 10 kg live fishes can be caught without any physical damage. Another morning or after 4 to 5 hours fishes can be collected from the upper hole. Interestingly some time water snakes are also caught in the Dhiri. (Illustrated in plate 9.1)
Kurjar
Reported from Mendha, this is active method of the fish trapping. Kurjar is a dome of Bamboo (Shape just like satellite antenna disc) made up of 12 bamboo sticks (Locally called Kurjar Guta) arranged in circle and tighten to each other with the help of rope. To these sticks, nylon mesh is tightly attached (Initially instead of nylon threads fiber made up of Boyal tree were in use). Mesh size measured 15 X 15 mm at lower wide end and 20 X 20 mm towards rear end. After assembly, circumference of the dome becomes 21.5 feet (6.6 m) and height becomes 130 cm. Its application is very interesting, during monsoon flood when the shoal of migrating fishes seen by knowledgeable individual, running from the bank into river Kurjar drop on migrating fishes. Fishes trapped under Kurjar collected by hand. Observation during its application reveals that it was not much effective; as it is very much time consuming compared with the low yield. To use Kurjar it is important to have knowledge about the migratory behavior of the fishes. (Illustrated in plate 9.2)
