Abstract
A research was made into the fish-luring effect of flotsam using the fishing records of the purse-seine boat operating on the sea near New Guinia. The results obtained may be summarized as follows:
1) T-shows that a moderately-aged flotsam with fouling animals has the best luring effect, a rotted one comes next, and a fresh one has the worst luring effect.
2) The fish-luring effect of flotsam drifting alone is better than that of assembled flotsam in current-boundary.
3) Flotsam with small bait fish or sea birds has a better luring effect than one without them.
4) It is estimated that a moderately-aged flotsam with fouling animals will lure 0.5-18.3 tons of fish per day.
