Experimental research on vertical line using different bait and hook size to catch hairtail has been conducted in Palabuhanratu waters. Three kinds of bait were hairtails (Trichiurus sp.), sardine (Sardinella sp.), and mackerel (Rastrelliger sp.). Number of hooks consisted of 8, 9 and 10. All fishing operations were done on floating lift net. From the experiment, bait of sardine was more effective to catch hairtails of Trichiurus savala than hairtails and mackerel. The three baits cought 69, 54 and 46 hairtails of Trichiurus savala, respectively. While, bait of hairtails was more suitable to catch hairtails of Trichiurus haumela. Bait of hairtails, sardine and mackerel cought 11, 7 and 1 hairtails of Trichiurus haumela. Hook number 8 gave the greatest number of catch, i.e. 62 hairtails of Trichiurus savala and 11 hairtails of Trichiurus haumela.
