    Abstract
    Research on the Reproduction Biology of Tuna (Euthynnus affinis) Landed at the Tanjung Beringin Fish Auction Place (TPI) Serdang Bedagai Regency, North Sumatra Province, was conducted in July-September 2021. The purpose of this study was to determine growth patterns and aspects of fish reproduction biology landed at the Tanjung Beringin TPI, Serdang Bedagai Regency. The method used in this research is purposive sampling method with sampling once for each month. The number of fish samples was 101 fish with total weight (TW) ranging from 334-3184 g and total length (TL) ranging from 300-577 mm. The results of the relationship between length and weight show that the growth pattern of tuna is isometric (b=3) where the increase in weight is the same as the increase in length. The condition factor of tuna fish ranged from 1.22 to 1.38. The results of reproduction show that the sex ratio of tuna is not balanced. The gonad maturity levels obtained were male tuna TKG I, II, III, IV and female tuna TKG I, II, III, IV. The fecundity of tuna fish ranged from 6880.682 to 131570.9 grains. And the diameter of tuna eggs is classified as partial spawner
     
    Penelitian mengenai Biologi Reproduksi Ikan Tongkol (Euthynnus affinis) yang Didaratkan di Tempat Pelelangan Ikan (TPI) Tanjung Beringin Kabupaten Serdang Bedagai Provinsi Sumatera Utara telah dilakukan pada bulan Juli-September 2021. Tujuan dari penelitian ini adalah untuk mengetahui pola pertumbuhan dan aspek biologi reproduksi ikan tongkol yang didaratkan di TPI Tanjung Beringin Kabupaten Serdang Bedagai. Metode yang digunakan dalam penelitian ini adalah metode purposive sampling dengan pengambilan sampel satu kali untuk setiap bulannya. Jumlah sampel ikan sebanyak 101 ekor dengan Berat Total (TW) berkisar 334-3184 g dan Panjang Total (TL) berkisar 300-577 mm. Hasil hubungan panjang dan berat menunjukkan bahwa pola pertumbuhan ikan tongkol isometrik (b=3) dimana pertammbahan berat sama dengan pertambahan panjang. Faktor kondisi ikan tongkol berkisar antara 1,22–1,38. Hasil reproduksi menunjukkan bahwa nisbah kelamin ikan tongkol tidak seimbang. Tigkat kematangan gonad yang diperoleh yaitu ikan tongkol jantan TKG I, II, III, IV dan ikan tongkol betina TKG I, II, III, IV. Fekunditas ikan tongkol berkisar antara 6880,682-131570,9 butir. Dan diameter telur ikan tongkol tergolong partial spawner
