Hence, it is necessary to do this research Catch Product of Yellowfin Tuna. Results obtained from the study are expected to give an idea of yellowfin condition in the Indian Ocean. This research was conducted in April - May 2016 at the Benoa Port. Th e aim ed of this research was to determine condition of yellowfin tuna through the study of the length-weight relationship , condition factor , length at first capture , and asymptotic length (L∞) of yellowfin tuna in the Indian Ocean based on catches landed at the port of Benoa, Bali. Th is research used survey method . Data processing use d the software of Microsoft Excel and FISAT II. The results have show n the size of the yellowfin tuna from Apri l- May 2016 ranging from 70 – 178 with 112 cmFL . The equation of length weights correlation was obtained W = 0.00002*FL 2,966 with isometric growth pattern. The condition factor obtained wa s between 1.64 to 2.44, and the size of the first caught fish is 133 cmFL. A symptotic length (L∞) = 190.05 cmFL. Based on the size of fish caught where Lc > ½ L∞ can be stated that the size of which was caught had a decent catch.

Produksi ikan Madidihang yang cenderung menurun yang disebabkan oleh penangkapan yang berlebih dikhawatirkan dapat mengganggu kelestarian sumberdaya ikan Madidihang. Oleh sebab itu perlu adanya penelitian tentang hasil tangkapan ikan Madidihang.

Penelitian ini bertujuan untuk mengetahui kondisi ikan madidihang melalui telaah panjang-bobot, faktor kondisi, ukuran pertama kali tertangkap, panjang asimtotik (L∞) ikan Madidihang di Samudera Hindia berdasarkan hasil tangkapan yang didaratkan di Pelabuhan Benoa, Bali.
