Ikan bawal putih (Pampus argenteus) mempunyai nilai ekonomis penting dan sebagai salah satu komoditas unggulan di perairan Tarakan. Informasi tentang biologi perikanan ikan tersebut masih terbatas. Penelitian ini bertujuan untukmengestimasi parameter populasi meliputi pertumbuhan, umur, mortalitas dan tingkat eksploitasi ikan bawal putih. Data frekuensi panjang bulanan dikumpulan pada Februari – Nopember 2013 dengan bantuan enumerator. Sebaran frekuensi panjang ikan dipisahkan kedalam sebaran normal menggunakan metode Bhattacharya pada progran FiSAT (FAO-ICLARM Stock Assessment Tools). Estimasi parameter populasi dengan aplikasi model analitikmenggunakan program ELEFAN-1 (Electronic Length Frequency Analysis). Hasil penelitian menunjukkan ukuran panjang ikan bawal putih berkisar antara 9,0 cm–35,0 cmFL. Hubungan panjangberat ikan bawal putih yang tertangkap dengan jaring insang bersifat allometrik negatif mengikuti persamaan W= 0,187L2,374. Nilai rata-rata panjang ikan pada saat pertama kali tertangkap (Lc) sama dengan ukuran pertama kali matang gonad (Lm). Laju pertumbuhan (K) sebesar 0,52/tahun dan panjang asimptotik (L ) sebesar 37,28 cmFL. Persamaan pertumbuhan dari Von Bertalanffy sebagai Lt = 37,28 (1 – e-0,52(t-+0,07)). Mortalitas alami (M) adalah 1,11/tahun, mortalitas karena penangkapan (F) = ,65/tahun dan mortalitas total (Z) = 1,65/tahun. Laju pengusahaan (E) sebesar 0,60 berarti tingkat eksploitasinya sudah melebihi dari nilai optimal (E=0,5) atau populasi ikan bawal putih dalam keadaan lebih tangkap (over exploited). Untuk itu diperlukan kebijakan pengelolaan secara hati-hati dengan mempertimbangkan aspek biologi dan aspek penangkapan yang sedang berjalan.White pomfret (Pampus argenteus) is one of the economically important fish and includes leading commodity in Tarakan waters. Information of fishing biology of those species were still limited. This study aims to determine the population parameters including growth, age, mortality and exploitation rate of white pomfret. Monthly length frequency data have been collected by enumerator from February to November 2013. Fish lengthfrequency distribution was separated into a normal distribution using the Bhattacharya method with software of FiSAT (FAO-ICLARMStock Assessment Tools). Estimation of population parameters were use analytical model application with ELEFAN-1 (Electronic Length Frequency Analysis) program. The results showed that lengths distribution of white pomfret ranged beetwen 9.0 cm -35.0 cmFL. Length-weight relationship was negatively allometric. Estimating the average length at first captured (Lc) was equal with average length at first maturity (Lm) with growth equation of Lt = 37.28 (1 - e-0, 52 (t +0.07)). Natural mortality (M) was 1.11/year, fishing mortality (F) was 1.65/yearand total mortality (Z) was 1.65/ year. The exploitation rate (E) was 0.60. It is mean that more higher than optimal exploitation so that the white pomfret fish population in a state of over fished. It is necessary to better policy in the management of white pomfret through precaution approach and describing of biologycal and fishing aspect in Tarakan, Kalimantan Timur.

ABSTRAKIkan kakap merah (L. gibbus) adalah jenis ikan demersal dari famili Lutjanidae yang bernilai ekonomis penting dan banyak tertangkap di Indonesia. Informasi tentang kebiasaan makan dan aspek reproduksi ikan kakap merah di Indonesia masih relatif sedikit. Selain itu, telah terjadi penurunan stok ikan kakap merah di Selatan Banten selama 6 tahun terakhir (2008)(2009)(2010)(2011)(2012)(2013). Penelitian ini bertujuan untuk mengkaji hubungan panjangberat, kebiasaan makan dan reproduksi ikan kakap merah.. Penelitian dilakukan selama 3 tahun (2013, 2015 dan 2016). Ikan contoh diambil dari hasil penangkapan ikan oleh para nelayan dengan alat tangkap pancing rawai dasar dan pancing ulur dengan mata pancing no 7-10 yang didaratkan di Binuangeun-Banten. Analisis fekunditas dilakukan di Laboratorium dengan metode gravimetrik. Hasil penelitian menunjukkan bahwa ikan kakap merah jantan memiliki ukuran lebih panjang dibandingkan ikan betina, pola pertumbuhannya bersifat isometrik. Kebiasaan makan ikan kakap merah tergolong ikan karnivora dimana makanan utamanya adalah ikan dan kepiting (Portunidae). Nisbah kelamin jantan dan betina tidak seimbang yaitu 1: 1.53. Fekunditas berkisar 14.050-596.243 butir dengan rata-rata 170 869 butir, diameter telur berkisar 0,03-1,02 mm dan pola pemijahannya bersifat salin sebagian (partial spawner). (2013, 2015 and 2016) Kata Kunci: Pertumbuhan; kebiasaan makan; reproduksi; kakap merah; Banten ABSTRACT The humpback red snapper (Lutjanus gibbus) is the family of lutjanidae which has important economic value in Indonesian capture fisheries. In addition, there has been a sharp decline on the population of humpback red snapper in the Southern part of Banten during the last 6 years (2008-2013). This study aims to examine the growth function, food habits and reproductive biology of L. gibbus in the Southern part of Banten Waters. Fish samples were collected for 3 years

Rajungan (Portunus peiagicus'' merupakan salah salu sumber daya hayati laut yang banyak dimanfaatkan oleh nelayan tradisionai. Rajungan di Teluk Jakarta selain sebagai sasaran penangkapan pada bubu cian jaring rajungan, juga tertangkap dengan sero, bagan, dan jaring arad Penelitian ini dilakukan pada tahun 2006 dengan tujuan untuk memperoleh informasi parameter stok dan selektivitas beberapa alat tangkap rajungan. Hasil pengamatan menunjukkan bahwa rajungan yang terlangkap mempunyai iebar karapas 4.16-11,9 cm dan boboi anlara 5.'1-113 g. Rajungan pertama kali tertangkap (Lcuo,o) pada sero, bagan, bubu, jaring rajungan, dan iaring arad pada ukuran lebar karapas 6,3: 7,3: 8,54; 8,96; dan 8,69 cm. Hampir semua (>95%i ralungan yang tertangkap dengan sero dan bagan merupakan rajungan kecil. Raiungan dewasa yang tertangkap pada jalng arad, bubu, dan Jaring rajungan diperoleh 4l, 66, dan 68%. Perbandingan keiamin jantan terhadap betina tidak sama pada alat tangkap yang digunakan. Hubungan antara lebar karapas dan panjang karapas pada sero, bagan, dan bubu rajungan mengikuti persamaan CW=o,4446 CL+0,1892 1r=3,9;. CW=o.431 4CL+0,347 5 (r=0,84J, dan CW=0,471 8C1+0,1 843 (r=0,83). Swimming crab, Portunus pelagicus ls one ot marine organism resources, intensively exploiled by aftisanal flsheres. fills crabis targeled species of trap and monofilalnent gili net and also as by catch of guiding barrier trap. fixed lift net. and monofilament gill net. The study was conducted in Jakarta Bay in 2006. The ob.tecti\/es of this study are to detemline papL ation parameters and seieclivity of swimmhg crab on several fishing gears used in Jakarta Bay. The swimning crabs werc caLtgl)t between 4.16-11 .9 cm in carapace widlh and between 5.1-113 g in weight. ihe firct captured (Lc sa-) of swimming crab caught by guiding barrier trap, fixed lift net, collapsible trap, beach se//]e. and monofilament gill net were 6.3, 7.3, 8.54. 8.69. and for 8.96 cnt. respectively. Guiding bamer trap and fixed iift net caught small crab for more than 95%. Large crab was caught by beach seine, collapsible trap, and monofilament gill net for crab were 41 , 66, dan 68% of the total catclt. The sex rutio between male and female diferred among the gears used. The relationship between CW and CL ol guiditlg barrier trap, fixed lifnet, bagan, and trap follows the equation CW=0.4446 CL+0.1892 (r=0 9) CW=o. 43 1 4CL+0. 3 47 5 (r=0. 84), and CW=o.47 1 8CL+0. 1 84 3 (r=0. 83 ).

Study on the population dynamic of endeavour shrimp (Metapenaus ensis) was conducted in Binuangeun waters based on data collected during period of survey, January to November 2016. The purpose of the study was to identify population parameters of the endeavour shrimp. Result showed that the endeavor shrimp growth pattern in Binuangeun waters was negative allometric and sex ratio of males and females was 1.0 : 2.7. The chi square test indicated that comparison of male and female of the endeavour shrimp was significantly different. It mean that there was imbalance in number between males and females. The length at first capture (Lc) of endeavour shrimp was 28.9 mm (carapace length),smaller than the length at first maturity (Lm) at 37.7 mm (carapace length). The growth parameter of endeavour shrimp was 1.33/year with maximum carapace length (Loo) of 51.45 mm. Instantenous total mortality (Z) and natural mortality (M) were 7.74/year and 1.88/year, respectively. While fishing mortality (F) and exploitation rate (E) respectively were 5.86/year and 0.76/year. The exploitation rate of endeavour shrimp in Binuangeun and adjacent waters was high. It was, therefore, recommended that fishing effort of the endeavour shrimp in that waters should be reduced about 52 % in the next year.
