Abstract

Freshwater eel (Anguilla spp.) is a catadromus fish that migrates from freshwater into seawater for spawning and return to freshwater during larvae stage to grow. The objective of this study was to determine species composition of tropical freshwater eels based on morphology collected from several rivers flowing in to the Palabuhan Ratu Bay. Young, adult, and glass eels were caught in August 2014 until Desember 2014. Glass eels were only caught in Cimandiri River. Freshwater eels were classified by ano-dorsal length (AD) divided by total length (TL), cluster analysis, and discriminant analysis based on morphometric data. The results showed different AD/TL of young and adult, i.e., 1.93±0.51 for A. bicolor bicolor, and 16.99±0.65 for A. marmorata, and three different AD/TL of glass eels i.e.,1.72±1.05 for A. bicolor bicolor6.60±1.79 for A. nebulosa nebulosa, and 15.07±1.04 for A. marmorata. Cluster analysis showed three groups of population  characters of young and adult eels i.e.  A. bicolor bicolor (2 groups) and A. marmorata (1 group). Discriminant analysis showed three groups of glass eels population i.e., A. bicolor bicolor, A. nebulosa nebulosa, and A. marmorata. Morphological identification showed that young and adult eels in Cibareno  and Citepus rivers had two species i.e., A. bicolor bicolor and A. marmorata. Glass eels from Cimandiri river had three species i.e., A. bicolorbicolor, A. nebulosanebulosa, and A. marmorata. A. bicolor bicolor was found in each rivers and as a dominant species in Palabuhan Ratu Bay.Keywords: A. bicolor bicolor, A. marmorata, A. nebulosa nebulosa, species composition

Abstract

The existence of horseshoe crabs Tachypleus gigas is currently on the threatened condition and its population status is also unclear. The objectives of this research were to asses the horseshoe crabs morphological characters and to identify based on molecular marker of Cytochrome Oxydase Subunit I (COI) gene. The samples were collected from five locations (Segara Menyan Subang, Ujung Kulon Banten, Tambak Lorok Semarang, Betah Walang Demak, and Kenjeran Surabaya) in October 2014 until June 2015. A total of 27 parameters for 62 individuals were used to determine connectivity and character identifier among populations. Data were tested using non-parametric analysis. While, the 5 individuals from each sites were used for molecular analysis including several stages of the DNA extraction, DNA electrophoresis, amplification and visualization of DNA fragments, and DNA sequencing. The results obtained based on morphological characters that T. gigas of Surabaya formed a unique group due to its body size (X1-X2 and X4-X16) was larger than the other 5 body parts (X22, X23, X26-X28) of Semarang, Demak, Subang, and Banten. According to molecular results, there were 650 bp conserve nucleotide sequences. Analysis using software MEGA 5.0 showed that there were 73 existence of specific nucleotide sites that can be used to distinguishes between T. gigas in-groups  and out-groups (T. gigas from Central Arabian Sea, T. tridentatus from Sweden, and Carcinoscorpius rotundicauda from USA).Keywords: horseshoe crabs, Java coast, morphology, identification molecular, CO1 gene.

Abstract

Kekerangan adalah organisme laut yang kosmopolit, mendiami substrat perairan dan bersifat sedenter(bivalvia) sehingga organisme tersebut sangat rentan terpengaruh oleh perubahan lingkungan. DiPerairan Indonesia terdapat beberapa jenis kekerangan. Salah satunya pusat penyebaran danpenangkapan kekerangan di Indonesia adalah Perairan Karangantu dan Labuan, Provinsi Banten. Jeniskekerangan yang dominan di perairan tersebut adalah famili Arcidae. Kondisi lingkungan perairan yangberbeda akan mempengaruhi morfologi dari setiap spesies kekerangan. Penelitian ini bertujuan untukmengidentifikasi morfologi pada famili Arcidae di Perairan Karangantu dan Labuan. Metode penelitianyang digunakan adalah deskriptif komparatif dengan teknik survei. Lokasi penelitian yang dipilih yaituPerairan Karangantu dan Labuan, masing-masing dua stasiun. Setiap stasiun memiliki karakteristikkondisi lingkungan yang berbeda, seperti daerah Muara Sungai dan daerah industri. Sampel kerangdiambil dengan metode sapuan menggunakan alat tangkap kerang (garuk). Sampel dari setiap spesiesditangkap sebanyak 25 individu/stasiun. Setiap spesies memiliki karakteristik morfologi yang berbeda,walaupun beberapa individu memiliki kesamaan ciri morfologi antara satu stasiun dengan stasiun lainnya.Potensi sumberdaya kekerangan di Perairan Karangantu yaitu A. granosa dan A. antiquata, sedangkan diPerairan Labuan yaitu A. granosa, A. scapha dan B. barbata. Secara umum potensi sumberdayakekerangan di provinsi banten yaitu A. granosa dengan ukuran cangkang terbesar di Perairan Lab

Abstract

Ikan teri (Stolephorus commersonnii) merupakan ikan pelagis kecil yang memiliki nilai ekonomis dan ekologis penting. Tujuan penelitian ini adalah menganalisis beberapa parameter dinamika populasi dan status stok ikan teri (Stolephorus commersonnii) di Teluk Palabuhanratu. Penelitian dilakukan pada bulan Mei hingga September 2017 pada periode bulan gelap dengan metode yang digunakan Penarikan Contoh Acak Sederhana (PCAS) dan holistik. Hasil penelitian menunjukkan bahwa ikan teri memiliki pola pertumbuhan alometrik negatif. Berdasarkan analisis model produksi surpus menggunakan model Fox, ikan teri berstatus overexploited. Upaya pengelolaan yang dapat dilakukan adalah pengendalian eksploitasi melalui penerapan alat tangkap ramah lingkungan.
