Ikan tenggiri (scomberomorus commerson) merupakan spesies yang menjadi target tangkapan oleh nelayan diseluruh daerah indonesia. tujuan dari penelitian ini menyediakan informasi nilai dari variabel dinamika populasi yang mencakup: model dan sifat pertumbuhan ikan tenggiri, reproduksi ikan tenggiri, ukuran pertama kali matang gonad dan tertangkap ikan tenggiri (s. commerson) dari hasil tangkapan jaring insang hanyut (drift gillnet) di perairan tanjung pasir kota tarakan. penelitian ini dilaksanakan pada bulan mei, juli dan agustus 2018. metode penelitian menggunakan metode deskriptif kuantitatif. pengambilan sampel dilakukan dalam 6 kali trip, setiap trip sampel berjumlah 6 ekor ikan. pertumbuhan ikan tenggiri mencapai panjang 80,25 cm, panjang maksimal 76,23 cm tingkat kepercayaan mencapai 95%, nilai koefesien pertumbuhan k berkisar 0,43/tahun dan nilai lifespan-nya mencapai 3,3 tahun. persamaan regresi y = 2,765x - 1,7275 menghasilkan nilai b 2,765 (b < 3) = pertumbuhan allometri negative. tkg i-v ditemukan hampir pada setiap waktu pengambilan sampel. nilai tertinggi ikg sebesar 12,29% (ikg v), nilai terendah ikg sebesar 0.27% (ikg i). nilai fekunditas terbesar berjumlah 57.719 butir telur (tkg v), rasio hasil tangkapan ikan tenggiri jantan dan betina 3,5 : 1. penelitian ini didapatkan nilai lm ikan tenggiri diketahui sebesar 45.12 cm dan nilai lc sebesar 36.757 cm. kata kunci: reproduksi ikan, ukuran pertama kali matang gonad, ukuran pertama kali tertangkap, ikan tenggiri

Mackarel fish (scomberomorus commerson) is a species that is targeted by fishermen throughout indonesian. the purpose of this study provides information on the values of population dynamics variables which include: the model and growth properties of mackerel, mackerel reproduction, size of the first maturity and capture by mackerel (s. commerson) from drift gillnet in tanjung pasir waters, tarakan. this research was conducted in may, july and august 2018. the research method used descriptive quantitative methods. sampling was done in 6 trips, each sample trip was 6 fish. the growth of mackerel fish reaches a length of 80.25 cm, a maximum length of 76.23 cm confidence level 95%, the value of a coefficient of growth k ranges from 0.43 / year and the value of lifespan reaches 3.3 years. regression equation y = 2,765x - 1,7275 produces a value of b 2,765 (b < 3) = growth of negative allometry. tkg i-v is found almost at each sampling time. the highest ikg value is 12.29% (ikg v), the lowest value of ikg is 0.27% (ikg i). the largest fecundity value amounted to 57,719 eggs (tkg v), the ratio of catches of male and female mackerel fish 3,5: 1. this study found that the value of mackerel fish was known to be 45.12 cm and lc value of 36,757 cm. key words: fish reproduction, length at first maturity, length at first capture, mackerel
