      Abstract
      Ikan layur (Trichiurus sp.) merupakan ikan demersal ekonomis penting yang sering dimanfaatkan untuk tujuan ekspor. Tingginya permintaan ekspor menyebabkan meningkatnya upaya penangkapan. Sifat ikan layur yang mempunyai ruaya rendah serta kecenderungan menetap, sehingga memiliki daya tahan yang rendah terhadap tekanan penangkapan. Produksi ikan layur di PPI Cikidang mengalami penurunan sebesar 27.846 kg tahun 2020 menjadi 21.925 kg tahun 2021. Penentuan pola musim penangkapan dan menentukan ukuran ikan layak tangkap dengan mengestimasi ukuran ikan pertama kali matang gonad (length at first maturity) penting dalam upaya penangkapan yang lebih efektif dan berkelanjutan. Hasil penelitian menunjukan bahwa 82% ikan layur di lokasi studi layak tangkap, yakni dengan length at first maturity (Lm) sebesar 50,6 cm. Catch Per Unit Effort (CPUE) tertinggi dari alat tangkap drift gillnet tahun 2017-2021 terjadi pada tahun 2018 dengan musim puncak penangkapan ikan layur terjadi selama 6 bulan yaitu pada musim timur (Juli, Agustus, dan September) musim peralihan (Oktober, dan November) dan musim barat (Desember).
       
      The hairtail fish (Trichiurus sp.) is an economically important demersal fish targeted for the export market. The high demand for exports has led to an increase in fishing efforts. The hairtail fish is a demersal fish with behaviour of low fecundity and is relatively sedentary, resulting in being subject to fishing pressure. The hairtail fish landing in PPI Cikidang tend to decline from 27,846 kg in 2020 to 21,925 kg in 2021. Determining the seasonal fishing pattern and establishing the allowable capture size of the fish by estimating the length at first maturity (Lm) is biologically important to as basic information in achieving more effective and sustainable fishing management. The research results showed that 82% of the hairtail fish sample from the study location exceeded the Lm, and biologically allowable to sustainable catch, with a length at first maturity (Lm) of 50.6 cm. The highest Catch Per Unit Effort (CPUE) from drift gillnet fishing gear from the year 2017 to 2021 was recorded in the year 2018, with the peak fishing season for the fish occurring for six months, specifically during the eastern season (July, August, and September), the transitional season (October and November), and the western season (December).
