Salah satu jenis ikan bernilai ekonomis tinggi yang terdapat di perairan ini adalah ikan Bawal Hitam ( Parastromateus niger ). Bawal Hitam tertangkap pada alat tangkap payang. Dalam mengelola sumberdaya Bawal Hitam dibutuhkan data aspek biologi. Tujuan dari penelitian ini adalah mengetahui hubungan panjang berat, faktor kondisi, ukuran pertama kali tertangkap, ukuran pertama kali matang gonad, tingkat kematangan gonad ikan, indeks kematangan gonad, fekunditas dan CPUE harian Bawal Hitam yang didaratkan di Tempat Pelelangan Ikan (TPI) Tawang, Kabupaten Kendal. Selain itu, untuk mengetahui CPUE harian Bawal Hitam. Penelitian dilaksanakan bulan Desember 2014 dan Januari 2015. Metode yang digunakan pada penelitian ini adalah pengumpulan data primer dan data sekunder. Hasil penelitian yang diperoleh adalah pola pertumbuhan Ikan Bawal Hitam bersifat allometrik negatif dengan persamaan W=0,0004L 2,923 . Ukuran rata-rata pertama kali tertangkap Ikan Bawal Hitam (L 50% ) adalah 225 mm. Nilai L∞ sebesar 335,79 mm dan 1/2 L∞ sebesar 177,89 mm. Nilai faktor kondisi Ikan Bawal Hitam selama penelitian adalah 1,19. Persentase terbesar tingkat kematangan gonad Ikan Bawal Hitam jantan terdapat pada TKG 2 yaitu 29% sedangkan Ikan Bawal Hitam betina persentase terbesar terdapat pada TKG 3 yaitu 62 %. IKG yang kecil untuk jantan berkisar antara 0,06 sampai 3,53 dan betina berkisar 0,08 sampai 5,71. CPUE Bawal Hitam pada bulan Desember 2014 13,48764 kg/trip. Rata-rata CPUE Bawal Hitam bulan Januari 2015 sebesar 6,745776 kg/trip. Kendal waters have the potential fishery. One of the high-value fish species found in these waters are fish Black Pomfret (Parastromateus niger). Black pomfrets were caught in payang fishing gear. Data of biological aspect is needed in order to manage Black pomfret resource. The purpose of this research was to determine the long-weight relationship, condition factor, the size of the first captured, the size of the first ripe gonads, gonad maturity level (GML), gonad maturation index, fecundity and daily catch per unit effort of Black Pomfret landed at the fish auction place (TPI) Tawang, Kendal. The study was conducted in December 2014 and January 2015. The research collected both primary and secondary data. The results obtained that Black pomfret fish growth pattern in negative allometric equation W = 0,0004L 2,923 . The average of first caught size of Black Pomfret fish (L 50% ) was 225 mm. L∞ obtained by 335.79 mm and 1/2L∞ value of 177.89 mm. The value of Black pomfret fish condition factor in this research was 1.19. The largest percentage of male Black pomfret fish level gonad maturity contained in the GML 2 that is 29% while the percentage of female Black pomfret fish are most at GML 3 is 62%. Black pomfret average CPUE in December 2014 was 13,48764 kg/trip. Black pomfret average CPUE in January 2015 was 6,745776 kg/trip. }, issn = {2721-6233}, pages = {1--9} doi = {10.14710/marj.v4i4.9762}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/9762} }
