Traditional riverine fish catching devices operated in the Barak, Dhaleswari, Jatinga, Brahmaputra, Dhansiri and Dorika rivers, in Assam have been studied with regard to their structure, operation and productivity. The study revealed the occurrence of 18 types of fish catching devices, which have been categorized into seven groups, viz., (i) hook and line gear (lar barshi and kupa barshi), (ii) traps (dori, polo, dhu, hogra and chairon jal), (iii) towed gear (km jal and pelain jal), (iv) dip nets (dheki jal and dorar jal), (v) entangling gillnets (patan jal ), (vi) seines (maha jal, pan jal and basta jal) and (vii) falling gears (jhaki jal, rekh jal and utar jal). The trap polo of river Dorika obtained the highest catch per man-hour (22.52 kg) followed by jhaki jal in river Brahmaputra (1.11 kg) and polo in river Barak (1.00 kg). Maha jal, though a massive gear, has given poor catch per man-hour (< 0.005 kg).
