چکیده
Penelitian bertujuan untuk mengkaji aspek morfometri dan biologi reproduksi ikan tongkol lisong (Auxis rochei, Risso 1810) yang didaratkan di Pangkalan Pendaratan Ikan (PPI) Kedonganan. Aspek meliputi sebaran panjang hubungan berat ikan, sedangkan kematangan gonad diamati secara histologis berdasarkan perkembangan sel gonad. Hasil penelitian menunjukkan memiliki antara 16,5 - 35,3 cmFL tubuh 64,8 539,4 gram dengan pola pertumbuhan bersifat allometrik positif (b>3). Secara umum PPI Kedonganan didominasi TKG sudah matang (TKG III, IV V) sebanyak 123 ekor (58,85 %) pada kisaran 22 23 cmFL. Perkembangan tidak bersamaan mengindikasikan bahwa asynchrounous (pemijahan berganda / multiple spawning) periode mijah sekaligus (partial spawning).
