Freshwater crayfish (Cherax quadricarinatus) as an invasive species has high capability to adapt in most waters in Indonesia. The extant distribution of this species in Indonesia causes observation of morphological charactersÃÂ is important to be established. This study purpose is to compare the morphological characters of Cherax quadricarinatus from several locations in Indonesia waters, such as the river in Bintan Island, Toba Lake, and Lido Lake. The total of morphological characters was measured in twenty-two characters. The result of the Kruskal-Wallis test represented nine different characters between Toba, Bintan, and Lido. Cluster analysis illustrated the highest level of similarities between Toba and Lido. The growth rate of the dactyls, and carapace width, and ocular carapace length between Toba and Lido were similar, meanwhile between Toba and Bintan were different. C. quadricarinatus originating from river waters in Bintan Island has a different morphological character from Lake Lido and Lake Toba. The differences in morphological characters between locations are caused by differences in habitat characteristics in rivers and lakes.

Sungai merupakan habitat makhluk hidup dimana terjadi hubungan timbal balik antara makhluk hidup dengan lingkungannya. Sungai yang merupakan habitat ikan sidat (Anguilla spp.) harus tetap terjaga agar pertumbuhan dan perkembangan tidak terganggu serta keberadaannya tetap lestari. Ikan sidat pada stadia larva akan bermigrasi dari laut ke perairan sungai hingga hulu dan setelah dewasa akan kembali ke laut untuk memijah. Penelitian ini bertujuan untuk menganalisis orde sungai dan mengkaji distribusi stadia ikan sebagai dasar penentuan daerah perlindungan ikan sidat (Anguilla spp.) di DAS Cimandiri, Jawa Barat. Penelitian ini dilakukan pada bulan Desember 2014 dan April 2015 meliputi tracking sungai (pengamatan habitat sungai, pengamatan aktivitas penangkapan, dan wawancara), analisis orde sungai, dan penentuan distribusi tiap stadia ikan sidat. DAS Cimandiri memiliki panjang sebesar 69,5 km dengan komposisi sungai permanen (permanent) dan sungai periodik (intermittent) memiliki orde sungai dari 1 hingga 7. Terdapat 56 sungai permanen bagian DAS Cimandiri yang merupakan sungai dengan orde sungai 1. Sungai dengan orde sungai 1 merupakan bagian hulu yang kondisi habitat dan perairannya masih baik. Beberapa dari bagian sungai yang memiliki orde sungai 1 dapat ditetapkan sebagai daerah perlindungan ikan sidat (Anguilla spp.). Distribusi berdasarkan stadia menunjukkan bahwa ikan sidat memiliki komposisi stadia yang tercampur, tetapi glass eels terdistibusi hanya pada 5 km dari arah laut. Adanya perbedaan stadia dari setiap bagian sungai maka diperlukan pengelolaan yang berbeda pula pada masing-masing bagian sungai tersebut.

Truss Morphometric Approach for population kinship analysis of Cherax quadricarinatus (Von Martens, 1868) in West Java Waters: Pendekatan Truss Morphometric Dalam Menganalisis Kekerabatan Populasi Cherax quadricarinatus (Von Martens, 1868) Di Perairan Jawa Ali Mashar; Yuyun Sri Wahyuni; Agus Alim Hakim; Yusli Wardiatno

Freshwater crayfish (Cherax quadricarinatus) is originate from Australia and Papua New Guinea waters. Morphometric measurement is one of the technique for differentiating body shape from a population. This study aimed to analyze the population kinship of freshwater crayfish in West Java with truss morphometric approach. Several morphometric characters were conducted measurement with a total of 133 individuals including 20 individuals from Darma Dam, 38 individuals from Kemang Lake, and 75 individuals from Kemuning Lake. The result of cluster analysis was obtained that the population of Cherax quadricarinatus from Kemuning Lake had closer relation with Kemang Lake than with Darma Reservoir. The differences in morphometric characters were alleged to be caused by differences of environmental conditions in three populations. Discriminant analysis showed that C. quadricarinatus from Darma Reservoir, Kemang Lake, and Kemuning Lake appropriately classified as 100%, 63.2%, and 76% respectively. Meanwhile, there were four main characters that differentiated the population from the three locations (C4, B5, D6, and A6).

Species Validation of Mole Crabs Based on Molecular Marker of 16s rRNA from Bantul and Purworejo waters: Validasi Spesies Undur-Undur Laut Berdasarkan Penanda Molekuler 16s rRNA dari Perairan Bantul dan Purworejo Nurlisa A Butet; Inge Anggraeni Bela Putri Dewi; Zairion Zairion; Agus Alim Hakim

Mole crabs live in intertidal areas of sandy beaches. Identification of aquatic species is often due misidentification cause by the cryptic phenomenon, so it is needed identification technique with a molecular approach by DNA barcoding. The study was purposed to validity and analyze kinship of the mole crabs based on 16S rRNA molecular marker from Bantul and Purworejo waters. Commercial kit of Gene Aid was used to isolation and extraction of DNA and was produced three total DNA from each location. DNA total with good quality was continued to amplified process using PCR technique with a primer of 16S rRNA. Sequence products of 16S rRNA gene were aligned with several sequences of species other from genus Emerita, Scylla, and Portunus that was found from GenBank. Species validation was performed using BLASTn. Genetic distance and phylogenetic tree were obtained MEGA 5.0 program. The samples of mole crab from Bantul and Purworejo were insignificantly different and the samples were from the same genetic sources.

The sperm whale (Physeter macrocephalus) is a protected marine biota in Indonesia. Molecular identification of sperm whales from the Sawu Sea (East Nusa Tenggara, Indonesia) was carried out using the 16S rRNA gene. This study aims to validate the species of the sperm whale (Physeter macrocephalus) in Indonesia using the partial cytochrome oxidase subunit I (COI) gene. The specimens used were tissue specimens from laboratory collections taken from Sawu Sea waters in 2014. The three samples were validated as Physeter microcephalus with 100% similarity. The base composition is dominated by the base thymine (31.7–31.8%) with a GC content of 42.7–42.8%. The genetic distance for the same species was 0.0015, while the highest genetic distance for Orcaella brevirostris was 0.2128. Molecular identification using the 16S rRNA gene and COI has validated the species of a sperm whale (Physeter macrocephalus) in Indonesia so that this genetic data can be used as a basis for sperm whale resource management and conservation.

Salah satu ikan endemik di perairan Danau Matano adalah Telmatherina antoniae. Ikan tersebut memiliki potensi sebagai ikan hias karena keunikannya. Tujuan dari penelitian ini adalah untuk menganalisis pertumbuhan ikan di danau tersebut. Penelitian dilakukan pada bulan Maret 2018 – Februari 2019 di Danau Matano, Sulawesi Selatan. Ikan tersebut memiliki pola pertumbuhan allometrik negatif dan positif. Nilai faktor kondisi T. antoniae jantan dan betina terendah berada di daerah Wotu Pali dan yang tertinggi berada di Sungai Petea. Faktor kondisi T. antoniae betina terendah pada Juni 2018 dan tertinggi pada Maret 2018, sedangkan faktor kondisi T. antoniae jantan terendah pada Oktober 2018 dan tertinggi pada Januari 2019. Koefisien pertumbuhan T. antoniae betina lebih besar daripada jantan, Persamaan pertumbuhan T. antonaie Lt = 104,49 [1-e-0,22(t+0,54)] dan ikan T. antonaie betina Lt = 103,37[1-e-0,28(t+0,42)].

Paus sperma (Physeter macrocephalus) merupakan salah satu mamalia laut yang dikategorikan dalam status vulnerable pada IUCN dan status Appendix I pada CITES. Identitas asli dari paus sperma secara molekuler dapat ditelusuri. Penelitian ini bertujuan untuk mengidentifikasi karakteristik molekuler paus sperma (P. macrocephalus) berdasarkan gen 16s rRNA parsial. Tiga contoh jaringan paus sperma yang dianalisis berasal dari perairan Laut Sawu, Nusa Tenggara Timur. Hasil identifikasi berdasarkan sekuen basa nukleotida gen parsial 16S rRNA menunjukkan bahwa ketiga contoh memiliki kemiripan dengan Physeter catodon sebesar 99%, dimana P. catodon merupakan sinonim dari P. macrocephalus. Pensejajaran sekuen nukleotida dengan outgroup (Balaenoptera physalus dan Balaena mysticetus) didapatkan nilai jarak genetik ketiga contoh dengan outgroup berkisar antara 0,0093–0,0726. Selain itu, didapatkan 25 nukleotida spesifik P. macrocephalus yang mampu membedakan dari spesies outgroup. Penelitian ini mampu memvalidasi spesies P. macrocephalus berdasarkan gen 16S rRNA dan dapat dijadikan sebagai marka molekuler yang kuat untuk identifikasi P. macrocephalus.
