KAJIAN ILMIAH IKAN GAR, FAMILI LEPISOSTEIDAE (Lepisosteus spp. & Atractosteus spp.): SPESIES ANCAMAN BAGI IKAN ASLI INDONESIA

Hadiaty, R.K. 2007. Scientific review of Gars, Family Lepisosteidae (Lepisosteusspp. & Atractosteus spp.): threat species for native Indonesian fish . ZooIndonesia 16 (2): 87-96. Indonesia is known as one of the countries with high fishdiversity. There are a lot of unexplore area which possibly have some undescribespecies. Damaging environment, poisoning and introduce species are very dangerousfor the sustainability of the native fish species in Indonesia. Gars are the alientpredator fish which prohibited to enter Indonesian waters since 1982, but the factsthere are many breeders of this species. This review paper is to discus the description,taxonomical history and the biology of gars. The aim of this paper is to build theawareness on the dangerous and destructive of this fish for Indonesian native specie

BEBERAPA CATATAN TENTANG ASPEK PERTUMBUHAN, MAKAN DAN REPRODUKSIIKAN NILEM PAITAN (Osteochilus jeruk Hadiaty & Siebert, 1998)

Osteochilus jeruk is one of the two new species of Osteochilus occuring in Gunung Leuser National Park, Aceh, Sumatra, Indonesia.It has a big size and beautiful colour, so it is potential as food and aquarium fish. Notes on growth, food and reproduction were examined as base for the culture of this fish

DIVERSITAS DAN HILANGNYA JENIS-JENIS IKAN DISUNGAI CILIWUNG DAN SUNGAI CISADANE

The fish research in Indonesian waters has been begun since 16 century ago. Most of the research collected fish around Batavia.Many new species was described and the type specimens deposited at the museums in Europe or America.The study of fish diversity and the lost of fish species was conducted at River Ciliwung and R. Cisadane in 2009. The aim of this study is to describe the recent fish diversity in both river drainages, then make a comparison with the number of species recorded based on the references data.The differences between the two datas show the number of species lost. The result of the study showed a total of 20 species of 13 families were collected in R. Ciliwung, while from the references data there were about 187 species, so the fish diversity lost in the Ciliwung river about 92.5%. The fish research in R. Cisadane were collected 39 fish species of 24 families. There were 135 species of 38 families of the references data, so the fish diversity lost in R. Cisadane is about 75.6%

KAJIAN ILMIAH IKAN PELANGI {Marosatherina ladigesi (Ahl 1936)} FAUNA ENDEMIK SULAWESI

Marosatherina ladigesi is one of the famous rainbow fish species from Sulawesi.This endemic fish species from Sulawesi is one of the Indonesian export commodity since more than 30 years ago.All of the export specimens come from the wild habitat.The anxiousness of the extinction of this species stated in the redlist of IUCN since 1994. Two field work of Maros Karst Project conducted in 2006, 2007 and an international expedition in 2007 showed the decreasing population of this species.The results of the three field trips showed the difficulties to get M. ladigesi in the streams.Taxonomical status and classification, coloration, sex dimorphism and distribution discussed

DNA BARCODING: FOUNDATIONS AND APPLICATIONS FOR SOUTHEAST ASIAN FRESHWATER FISHES

Identifying and delineating species are the primary tasks of taxonomy. Owing to the decreasing interest of the nations for taxonomy and the inventory of living beings, funds have been drastically decreasing during the last two decades for taxonomic studies. As a consequence, the worldwide pool of taxonomists has dramatically decreased. DNA barcoding, as an automated tool for species delineation and identification, proved to rejuvenate the field of taxonomy and open new perspectives in ecology and conservation. In the present review, we will discuss how DNA barcoding established as a new paradigm in taxonomy and how DNA barcoding has been recently integrated in taxonomic studies. We will further detail the potential applications for species identifications and discuss how DNA barcoding may positively impact the inventory and conservation of living beings, particularly in biodiversity hotspots. We emphasise the benefit of DNA barcoding for the conservation of Southeast Asian freshwater fishes

BIOGEOGRAPHY OF INDONESIAN FRESHWATER FISHES: CURRENT PROGRESS

Southeast Asia is one of the most geologically complex tropical regions on Earth, in which the intricate interactions among plate tectonics, volcanism and Pleistocene climatic fluctuations led to complex patterns of species distribution. An increasing number of biogeographic studies of the Indonesian ichthyofauna have already partially uncovered the potential mechanisms at the origin of present day species distribution. These studies are currently scattered in the literature and the present review aims at presenting recent progress. Here, we propose a review of this literature with the aim to provide a broad overview of the current progress in the field of Indonesian freshwater fishes biogeography. First, we will briefly present the geology of the Indo-Australian Archipelago (IAA) and highlight the time frame of the geographical settlement of the Indonesian archipelago. Second, we will present the palaeoecological history of Sundaland during the Pleistocene. Finally, we will present the results of recent biogeographic studies across the three biogeographic provinces (Sundaland, Wallacea, Sahul) and discuss how these results fit with geological and palaeoecological scenarios in Indonesia

Une espèce nouvelle de Sicyopterus (Gobiidae) d’Indonésie.

International audienceA new species of Sicyopterus, freshwater goby, is described from Sumatra and Java, Indonesia. It differs from other species belonging to the genus by a combination of characters including two lateral clefts on the crenulated upper lip, a second dorsal fin with one spine and 10 segmented rays, second and third rays of the first dorsal fin filamentous, more lateral, predorsal and transverse back scales, and a reddish caudal fin in male with a slight blue line on the upper and lower parts.Une espèce nouvelle de Sicyopterus, gobie dulçaquicole, est décrite sur la base de spécimens collectés à Sumatra et Java (Indonésie). Elle diffère des autres espèces du genre par plusieurs caractères incluant deux encoches latérales sur la lèvre supérieure crénelée, une seconde nageoire dorsale avec un rayon épineux et 10 rayons mous, les deuxième et troisième rayons de la première dorsale filamenteux, un plus grand nombre d’écailles en ligne longitudinale, en série prédorsale et transverse postérieure, ainsi qu’une nageoire caudale rouge bordée d’une ligne bleue chez le mâle

STRUKTUR BIBIR Osteochilus partilineatus KOTTELAT DAN PERBANDINGANNYA DENGAN 7 JENIS Osteochilus LAINNYA

Osteochilus is a genus of fish with large lips,everted, sucker-like, covered with more or less folds of plicae bearing numberous unicellulair keratinous projections or uncuil. The structure of thr lips Osteochilus is divided into three from i.e. ectomorph, mesomorph and endomorph, based on the length and shape of plicae on the lateral portion of the upper lip, the distribution of uncuil and taste buds on the plicae , also from the size and shape of uncuil. Osteochilus partlilineatus is a small fish which has a nice colour patteern, so it is potential as an ornamental fish. it has an ectomorph lips, which the structure of plicae,uncuil and taste buds. The from of the taste buds redemble the rose flower which are very different with the structures of that 7 other Osteochilus that were examined by Roberts using scaning Electro Microscope (SEM)
