Abstract

Pembeda dalam kelas timun laut (Holothuroidea, Echinodermata) adalah morfologi eksternal, organ internal, dan spikula. Karakteristik tersebut bisa menunjukkan tingkat kemiripan yang tinggi untuk  famili tertentu, termasuk famili Stichopodidae. Famili ini merupakan salah satu famili Holothuroidea (Echinodermata) yang mewadahi sebagian besar spesies komersial yang tersebar luas di perairan dangkal tropis. Sampai saat ini, evolusi timun laut berdasarkan karakteristik morfologis yang digunakan untuk menentukan status karakteristik yang dapat diaplikasikan ke dalam analisis filogeni masih dalam perdebatan. Bahkan, untuk famili Stichopodidae sendiri, belum ada yang melakukan penelitian filogeninya. Tulisan ini melaporkan hasil studi filogeni yang ditujukan untuk melihat kedekatan antara spesies anggota Stichopodidae yang ada di Indonesia. Spesimen yang digunakan dalam penelitian ini merupakan spesimen koleksi Pusat Penelitian Oseanografi LIPI yang terdiri dari sembilan spesies Stichopodidae (sebagai ingroup) dan dua spesies  Holothuriidae (sebagai outgroup). Konstruksi pohon filogeni dilakukan dengan menerapkan metode maksimum parsimoni dan program PAUP 4.0b, menggunakan 78 karakteristik morfologis. Penelitian ini menghasilkan dua pohon filogeni yang memisahkan secara konsisten genus Stichopus dari genus Thelenota  (bootstrap 99% and 100%). Posisi dalam setiap genusnya stabil. Kedua genus dari Stichopodidae memiliki jumlah synapomorf yang sama. Stichopus memiliki sepuluh karakteristik homoplasi, sedangkan Thelenota tidak memilikinya. Enam dari sembilan spesies Stichopodidae memiliki karakteristik autapomorf yang dapat digunakan sebagai karakteristik tingkat spesies

Abstract

Experiment on Holothuria atra provided evidence that asexual reproduction by fission was possible to be stimulated at laboratory. The success of the experiment was determined based on the high survival of stimulated individuals that grew into intact. After being tightened, induced individuals divided into anterior- and posteriorend individuals. During regenerating into intact individuals, the body weight decreased to relatively minimum weight. Developing of new tentacles in posterior-end individuals and anal aperture in anterior-end individuals required 7-8 weeks after fission. These indicators may lead to anatomical recovery which may be a sign of feeding necessity.

Abstract

More than 300 sea cucumber species have been recorded from Indonesian waters. This paper presents eight species which have been rarely reported. Actinopyga bannwarthi Panning, 1944, were found among fished sea cucumbers collected by fishermen in Kupang and Karimunjawa. Stichopus pseudohorrens Cherbonnier, 1967, was found in West Timor waters; Thelenota rubralienata Massin & Lane, 1991, and A. caerulea Samyn, Vandenspiegel & Massin, 2006, were collected from the reef in Halmahera, North Maluku. Four other species i.e. Bohadschia atra Massin, Rasolofonirina, Conand, Samyn, 1999; B. subrubra Quoy and Gaimard, 1833; Holothuria (Metriatyla) fuligina Cherbonnier, 1988, and H. (Thymiosycia) gracilis Semper, 1868, were discovered from Lombok waters. The latest mentioned species was also found among fished sea cucumbers in Karimunjawa. All species except T. rubralineata may be new records for Indonesia. In the case of H. (Thymiosycia) gracilis Semper, 1868, it was new record for Lombok waters, following its discovery from West Seram, Central Maluku.

Abstract

Indonesia has been supplying the highest diversity of dried sea cucumbers (trepang) to world markets for decades even though species validation on the trepang from any producing areas throughout the country is still needed. Karimunjawa (Islands off north coast of Java) is one of trepang habitats. Several visits from May to November 2009 had been made to collect trepang from the fishers and collectors in that area. Eighteen aspidochirote species were identified, more varied than those reported in 1988 and 1992 although 7 species have no longer been found. Three species among those: Actinopyga banwarthi, Bohadschia subrubra, and Holothuria fuscocinerea have never been reported in Indonesia before, neither on the list of commercial sea cucumbers in Asia nor world trade provided by Choo (2008) and Toral-Grande (2007). These species composition shifts may indicate a threat to species diversity, starting with excessive removal of natural stock. Up to now, 28 species of trepang have been recognized from Karimunjawa waters.

Abstract

Ovaries of Holothuria leucospilota consist of simple tubules, within which oocytes grew and reached maturity. The oocytes development started at the tubule lining and as the development proceeded, the oocytes increased in size and moved to the tubule lumen. An ultra-section-method was applied to describe ultrastructural changes in the oocytes during their development, leading to the knowledge on gametogenesis of sea encumber H.leucospiota. Primary previtellogenic oocytes embedded in tubule lining was the earliest stage, which were characterized by the presence of nuage. Prior to yolk formation, clusters of mitochondria appeared in the ooplasm. This may indicate the need for energy to produce yolk substance. When yolk bodies were common in vitellogenic oocytes, nuage became invisible and mitochondria were no longer in groups. As development progressed, abundant microvilli appeared on the surface of vitellogenic oocytes, but less common on postvitellogenic oocytes when maximum growth had been attained. This structure was suggested to facilitate size increase and functional efficiency of oocyte surface.

Abstract

This study was aimed to investigate diversity of sea cucumber. Samples were collected  in  the coastal  waters  of  Natuna,  Riau  Islands  in  June 2009. Samples were taken from 2 locations: Sepempang and Pengadah beach. Sampling was done by using a transect quadrant of 5x5 m. This  sampling and observation on  its  microhabitat  were conducted by snorkeling. Analyses on the sea cucumber community structure were based on its diversity, equitability, density and frequency of occurance. The result showed that at both  locations there  are 16  species from two families: Holothuriidae and  Stichopodidae.  The higher  diversity index  (H) was  3.256  and  equitability  index  (e) was 0.993.  The higher  density  of species were 0.0032 ind/m2. The higher frequency of occurance was 27.71% by H. atra.
