Fishing efficiency of conventional bamboo traps and other traps for eel Conger myriaster, was investigated. The results are as follows: ). The best fishing efficiency was observed when the trap is inclined to the sea bottom with 20 ~ 30 degrees. 2. Plastic traps were better compared with bamboo traps in rigidity and fishing efficiency. 3. Using clips in attaching branch line to main line, the operating time was saved somewhat considerably.
