“…Struktur ukuran panjang karapas udang jerbung (Penaeus merguiensis) di perairan Kepulauan Aru berkisar antara 16 -54 mm dan dominan tertangkap pada ukuran panjang karapas 32 mm. Hasil ini berbeda dengan struktur ukuran jerbung di berbagai perairan seperti di perairan Demak berkisar 19,9-48,0mm (Wedjatmiko & Yulianti, 2003); di perairan Sampit berkisar 18,0-58,0 mm (Nurdin & Kembaren, 2015): di perairan utara Jawa Tengah berkisar antara 14,0-68,0 mm (Tirtadanu & Ernawati, 2016); di perairan Tarakan berkisar antara 19,0-53,0 mm (Chodrijah & Suman, 2017); sedang di perairan Kotabaru berkisar 14,0-46,0 mm (Tirtadanu et al, 2017) serta di perairan Segara Anakan berkisar antara 11,0-42,0 mm (Wagiyo et al, 2018). Perbedaan struktur ukuran udang jerbung pada berbagai perairan tersebut disebabkan oleh adanya perbedaan kondisi oseanografi perairan (Motta et al, 2005).…”

Pemanfatatan sumber daya udang jerbung (Penaeus merguiensis) di perairan Kepulauan Aru dan sekitarnya sudah berlangsung cukup lama dan dilakukan sangat intensif. Untuk menjaga keberlanjutannya, dibutuhkan opsi pengelolaan agar sumber daya ini dapat dimanfaatkan secara berkesinambungan. Tujuan penelitian ini adalah untuk mengkaji status stok dan kemungkinan pengelolaan udang jerbung di perairan Kepulauan Aru dan sekitarnya. Penelitian dilakukan pada periode survei 2013-2017 dengan metode survei dan diperkaya dengan sintesis hasil-hasil penelitian di perairan Kepulauan Aru, Laut Arafura. Hasil analisis menunjukkan bahwa struktur ukuran udang jerbung berkisar antara 16-54 mm dengan perbadingan kelamin didominasi udang betina, sementara pola pertumbuhannya bersifat allometrik negatif. Ukuran udang jerbung yang tertangkap pada umumnya belum memijah. Laju pertumbuhan (K) udang jerbung sebagai 1,3/tahun dengan panjang karapas maksimum (Loo) 60,0 mm. Laju kematian total (Z) dan laju kematian alamiah (M) masing-masing 3,79/tahun dan 1,57/tahun. Laju kematian karena penangkapan (F) sebagai 2,22/tahun dan laju pengusahaan (E) sekitar 0,59/tahun, sementara spawning potential ratio (SPR) adalah 3 %. Dengan demikian status stok udang jerbung sudah berada pada penangkapan berlebih (overfishing). Untuk menjamin keberlanjutannya, maka perlu disusun opsi-opsi pengelolaan meliputi penutupan daerah/musim penangkapan pada bulan Maret, melakukan pengurangan upaya penangkapan sekitar 18 % dari kondisi saat ini dan penetapan ukuran udang jerbung terkecil yang boleh ditangkap yaitu pada ukuran panjang karapas 38,8 mm. The exploitation level of banana prawn (Penaeus merguiensis) resources in Aru Island and surrounding waters has been done very intensive for a long time and until now. To preserve the banana prawn resources, it needs management options to sustain the use of these resources. The aim of this study was to identify the stock status and management of banana prawn in Aru Island and surrounding waters. The research was conducted during 2013 to 2017 using survey methods and supplemented by the synthesis of investigation results from Aru Island waters. Results show that the banana prawn’s size structure ranged between 16-54 mm, the sex ratio was dominated by female and the growth pattern was negative allometric. Most of the banana prawn were caught in immature condition. The growth rate (K) was 1.3/year with maximum carapace length (L∞) of 60.0 mm. Total mortality (Z) and natural mortality (M) was 3.79/year and 1.57/year respectively. The fishing mortality (F) was at 2.22/year and exploitation level (E) was around 0.59/year, while the spawning potential ratio (SPR) was 3 %. Hence the banana prawn stock in Aru Island and surrounding waters is in overfishing condition. Management options are proposed in order to keep the sustainability of the resources, such as: closed area/season in April, reducing effort to 18% from current condition, and legal-size catch limitation at 38,8 mm.

White shrimp is one of the catches of fishermen using fishing gear in the Sekatak Bengara Estuary area, Bulungan Regency which has a fairly high economic value ranging from Rp. 28.000-Rp. 40.000,-. The purpose of this study was to analyze the characteristics of the growth and mortality model of white shrimp (P.merguiensis) in the Sekatak Bengara Estuary, Bulungan Regency. The research method uses descriptive quantitative methods. Sampling of P.merguiensis shrimp used fishing nets with purposive sampling method in the Sekatak Bengara Estuary, Bulungan Regency. The results showed that P.merguiensis shrimp with a total of 2253 samples with 750 male samples with the smallest size 53mm (age 13 days) and the largest size 129mm (aged 62 days), while the female sample was 1503 tails with the smallest size 55mm (age 18 days). and the largest size is 123mm (110 days old) with a sex ratio of 1.0:2.0. The growth model of male and female P.merguiensis shrimp was negative allometry with the male dominant body shape being thin and the female dominant having a fat body shape. The growth model of von Bertalanffy male shrimp has a maximum length of 151.894 mm (451 days old) has a growth speed of 0.03mm/day with a correlation of 64.29% and a female shrimp of 128.01mm (452 days old) has a growth rate of 0.052mm/day with a correlation of 80.07%. The mortality model of male and female shrimp obtained total mortality of 101.17% and 100.9%; catch mortality was 50.75% and 67.81%; natural mortality of 50.41% and 33.09%; exploitation rates of 50.17% and 67.2%, respectively.
