<![CDATA[Perairan Teluk Jakarta merupakan area dengan aktiftas tinggi, sehingga sumberdaya ikan didalamnya mengalami tekanan ekploitasi dan degradasi habitat. Udang jerbung (Penaeus merguensis) merupakan salah satu sumberdaya ekonomis penting dari Teluk Jakarta yang perlu dikelola supaya tetap lestari. Pada penelitian ini bertujuan untuk memperoleh data dasar dan informasi terkini mengenai struktur ukuran, aspek reproduksi, parameter populasi, kelimpahan dan daerah tangkapan udang jerbung di sekitar Teluk Jakarta. Pengambilan data melalui observasi dan enumerasi. Hasil penelitian didapatkan udang jerbung dari Teluk Jakarta mempunyai panjang karapas 19 - 64 mmCL dengan modus 30 mmCL, panjang karapas tertinggi di P. Harapan. Hubungan panjang-berat menunjukan sifat pertumbuhan allometrik negatif degan nilai b = 2,3044 dan R2 = 0.8021. Panjang karapas pertama kali tertangkap; jaring arad 33 mmCL, jaring rampus 32 mmCL, jaring cantrang 30 mmCL dan pertama kali matang gonad 34 mmCL. Nisbah kelamin mempunyai rasio jantan : betina = 1 : 1,07. Komposisi gonad matang tertinggi (puncak musim pemijahan) pada bulan Maret dan Oktober. Laju pertumbuhan (K) = 1,33 per tahun dan panjang infinity(L∞) = 54,35 mmCL. Laju kematian total (Z) = 5,89, kematian alami (M)= 1,85/tahun, laju kematian karena penangkapan (F)= 4,04/tahun dan tingkat pengusahaan (E)= 0,69. Indeks kelimpahan/Hasil tangkapan per unit usaha (CPUE) 1,71 - 4,18 kg/trip/hari dengan rerata 2,57 kg/trip/hari. Musim penangkapan pada Februari-Mei dan paceklik pada Juni-Desember. Untuk menjaga kelestarian udang jerbung di Teluk Jakarta perlu meningkatkan lebar mata jaring dan penutupan penangkapan di area pemijahan pada puncak musim pemijahan. Jakarta Bay waters are an area with high activity so that the fish resources in it are under exploitation pressure and habitat degradation. White shrimp (Penaeus merguensis) is one of the important economic resources of Jakarta Bay that needs to be managed to sustain. This study aims to obtain basic data and up-to-date information; size structure, reproductive aspects, population parameter, abundance and fishing ground of white shrimp in around Jakarta Bay. The data were collected through observation and enumeration. The results showed that white shrimp from Jakarta Bay had a carapace length of 19 - 64 mmCL with a mode of 30 mmCL, the highest carapace length in Harapan Island. The length-weight relationship shows negative allometric growth with the values of b = 2.3044 and R2 = 0.8021. The length first captures by of mini bottom trawl 33 mmCL, by gillnet 32 mmCL and by danish seine 30 mmCL and the length first gonad maturity 34 mmCL. The sex ratio has a male : female = 1 : 1,07. The highest ripe gonad (peaks spawning season) was in March and October. The growth rate (K) = 1.33/year and the infinity (L∞) length = 54.35 mmCL. Total mortality rate (Z) = 5.89/year, natural mortality (M) = 1.85/year, fishing mortality (F) = 4.04/year and exploitation rate (E) = 0.69. Catch per unit effort (CPUE) 1.71 - 4.18 kg/trip/day with an average of 2.57 kg/trip/day. The fishing season in February-May and famine in June-December. To maintain the sustainability of white shrimp in Jakarta Bay, it is advisable to increase the width of the mesh size and the closure of fishing in the spawning area at the peak spawning season.]]>
