This study was conducted to study the catch composition of Largehead hairtail (Trichiurus lepturus) hand and line and some biological characters of T. lepturus in northern waters of Oman Sea (Remin fishing port). Sampling was done by hand and line used in the region by four motor boats each of which included 4 fishermen from February to May 2022. 6955 fish were caught which include T. lepturus, Sphyraena jello, Carangoides chrysophrys, Terapon jarbua, Strongylura strongylura and Otolithes ruber. Among them T. lepturus with 97.66% had the highest percentage and O. ruber with 0.01% had the lowest percentage of catch. The maximum and minimum total length of T. lepturus caught were 128 cm and 42 cm, respectively. The optimal size of T. lepturus was 85.63 cm and the infinite length was estimated at 131.13 cm. Also, the length of sexual maturity was calculated as 66.57 cm. The results showed 84.36% of T. lepturus were mature and only 15.64% had a length less than the length of the first sexual maturity
