Description Squid (Loligo sp.) is one of the fisheries commodities caught in Manokwari waters. The aim of this study was to determine the biological aspects of Loligo sp. including the sex ratio, size distribution, growth pattern, and the lengthy relationship of Loligo sp. from Manokwari waters. This research was conducted in January until March 2017, in three landing sites of squid (Loligo sp) namely Fanindi Pantai, Borobudur and Arowi village. The method used is observation technique in the laboratory includes measurements of length and weight to find out the size distribution and growth pattern of captured Loligo sp. and surgery to determine the sex ratio. The male-female sex ratio of Loligo sp. was  1.3: 1.0 with a range of coat length and wight dominated by male. The growth pattern of Loligo sp in Manokwari waters is negative allometric, where the length increase is faster than the weight gain.
Cumi-cumi (Loligo sp.) adalah salah satu komoditi perikanan yang banyak tertangkap oleh nelayan di perairan Manokwari. Penelitian ini bertujuan untuk mengetahui aspek biologi Loligo sp. meliputi  rasio kelamin, sebaran ukuran, pola pertumbuhan, dan hubungan panjang-bobot Loligo sp yang tertangkap dengan alat tangkap pancing oleh nelayan asal Manokwari. Penelitian dilakukan pada bulan Januari sampai bulan Maret 2017, di tiga lokasi pendaratan cumi-cumi (Loligo sp) yang berada di Kabupaten Manokwari yakni : Kampung Fanindi Pantai, Borobudur, dan Arowi.  Metode yang digunakan yaitu teknik observasi analisis lanjutan di laboratorium meliputi pengukuran panjang dan bobot untuk mengetahui sebaran ukuran dan pola pertumbuhan Loligo sp yang tertangkap serta pembedahan untuk menentukan rasio kelamin. Hasil penelitian menunjukkan bahwa perbandingan jenis kelamin jantan-betina Loligo sp adalah  1,3 : 1,0 dengan didominasi oleh individu jantan di hampir semua selang kelas panjang mantel maupun bobot tubuh. Pola pertumbuhan Loligo sp di perairan Manokwari bersifat allometrik negatif, dimana pertambahan panjang lebih cepat dibanding pertambahan bobot.
