Abstract

The aim of the study is to investigate the reproduction aspects of Hampala sp and Osteochilus vittatus', wich is relationship between weight and lengths, maturity of the gonad, gonado somatic index (GSI) and fecundity. The research conducted from April to July 1997. The 49 sample of Hampala sp 21 sample was females and 28 sample was males . The length of Hampala sp female ranged 310 -410 mm, the weight ranged 320 - 753 gram. The male Hampala sp is length ranged 170 - 355 mm, the weight ranged 115 - 504 gram. The growth pattern of both is “isometric”. The first matured gonad was found at of 310 -330 mm length for female and 200.84-231.67 mm for male. Gonado Somatic Index for female ranged from 2.95 % - 7.74 % and for male ranged from 2.21 % - 3.07 %. The total ranged 88,442 -143,617 eggs. Nisbi fecundity was 4057 eggs/ gram of gonado weight. The 38 sample of Osteochilus vittatus 27 sample was female, the length ranged from 162 - 283 mm and weight ranged from 381.1 — 315.0 gram, 11 male at length ranged from 145 -226 mm and weight ranged 25.4 - 135.9 gram. The growth pattern for Osteochilus vittatus both is “isometric” .The first matured of the gonad was at of 182.18 - 202.35 mm length for female and at 145.00 - 165.25 mm for male. Gonado Somatic Index was ranged from 11.26 % -61.14 % and 2.35 % -14.09 % for male and female. The total fecundity was ranged from 28,140 - 129,042 eggs/gram weight of gonad AbstrakTujuan penelitian adalah untuk mengetahui aspek reproduksi ikan sasau (Hampala sp) dan ikan lelan (Osteochilus vittatus C.V.) di Danau Singkarak yang meliputi hubungan bobot dengan panjang, tingkat kematangan gonad, indeks somatik gonad (1SG) dan fekunditas.

Abstract

Mahalona, Lantoa and Masapi Lakes are three of the five beautiful lakes in South Sulawesi, the other two lakes are Matano and Town ti which bigger than those three. During the Dutch gouvemements there were several expedition to one, two or the five lakes. Rudolf Woltereck was the first biologist which visited and collected fishes from the all of the five lakes and published it in 1933. During 1988-1989, Dr, Maurice Kottelat recollected the fishes and found one new genus and about 8 new species, also designated the neotype of one species from Lake Towuti. A collaborative team between Indonesian Institute of Sciences (LIPI), Bogor Agriculture University and Forestry Department received a grant from Asean Regional Center for Biodiversity Conservation (ARCBC) to conduct the research in the five lakes. The results of this research are being reported in a series of scientific journal. The fish biodiversity of Lake Matano already published. This paper is the result of our interesting adventure to reach the three lakes and reporting their fish biodiversity. Twelveof the 17 of Mahalona’s fishes are the endemic species, while in Lake Lantoa there was 4 of the twelve and in Lake Masapi was only one of the twelve endemic fish species.

Abstract

Matano Lake is one of the five well known Malili complex in the South Sulawesi Province. The other four lakes are Mahalona, Towuti, Wawontoa and Masapi. Between the five lakes, Matano is the lake that lies in the highest place i.e 382 m above sea level, while the deepest part is 590 m. One research team from Research Center for Biology-IIS, Bogor Agriculture University and Forestry Service received fund from Asean Regional Center for Biodiversity Conservation (ARCBC, a joint cooperation project between ASEAN and the European Union) conducted a fieldwork at the three lakes Matano, Mahalona and Towuti. This paper is the result of four field works at Matano Lakes, while we plan to do 7 field works, so this result is a preliminary study. The results from the four fieldworks showed there were 18 fish species which is belong to 9 familia and distributed in 12 research stations. From 18 species collected, Telmatherina antoniae and Glossogobius matanensis are the common species at the almost all of the stations. It is interesting to found Telmatherina bonti in Lake Matano, this fish reported only occurred in Lake Towuti. AbstrakDanau Matano adalah satu dari lima danau di wilayah Propinsi Sulawesi Selatati yang dikenal dengan nama Malili Kompleks. Keempat danau lainnya adaiah Mahalona, Towuti, Wawontoa dan Masapi. Diantara kelima danau tersebut, Matano merupakan danau yang terletak di daerah yang tertinggi yaitu 382 m dari permukaan laut, sedangkan bagian terdalamnya mencapai 590 m.

Abstract

From 589 species freshwater fishes recorded as inhabitant of freshwater ecosystem in Sumatra, 58 species (9.8%) belong to endemic species for Sumatra. The highest endemicity by family is Belontiidae (42.3%). Based on list of aquatic biota species represented in ’’The 2000 IUCN Redlist of Threatened Species” (IUCN 2001), can be identified 14 species of freshwater fishes of Sumatra that belong to threatened species. Of these, 7 species (50%) are endemic to Sumatra i.e. Betta burdigala, B. chloropharynx (found only in Bangka Island), B. miniopinna dan B. spilotogena (found only in Bintan Island), Neolissochilus thienemanni (found only in Lake of Toba), Poropuntius tawarensis and Rasbora tawarensis (found only Lake of Laut Tawar). Geographic distribution of those endemic species were analysed by province as unit analysis. The high endemicity by province are West Sumatra (24.1 %), Jambi (20.7 %), Riau Islands (17.3 %), Nanggro Aceh Darussalam (17.3 %), and Riau (15.5%). However, nowadays those high endemicity threatened by various development activities. Factors that threaten the existence of those species were identified. AbstrakDari 589 jenis ikan air tawar yang tercatat sebagai penghuni ekosistem perairan tawar Sumatra, 58 jenis diantaranya (9,8%) termasuk kelompok ikan endemik Sumatra. Suku yang mempunyai endemisitas tertinggi adalah Belontiidae (42,3%). Berdasarkan daftar jenis biota air yang tercantum dalam “The 2000 IUCN Redlist of Threatened Species (IUCN 2001), dapat diidentifikasi 14 jenis ikan air tawar Sumatra yang terancam punah (threatened species) dan 7 jenis diantaranya (50%) adalah jenis-jenis ikan endemik Sumatra yaitu Betta burdigala, B. chloropharynx (hanya terdapat di P. Bangka), B. miniopinna dan B. spilotogena (hanya terdapat di P. Bintan), Neolissochilus thienemanni (hanya terdapat di D. Toba), Poropuntius tawarensis dan Rasbora tawarensis (hanya terdapat di D. Laut Tawar). Distribusi geografis ikan endemik Sumatra dianalisis dengan provinsi sebagai unit analisis. Provinsi yang memiliki endemitas tinggi adalah Sumatra Barat (24,1 %), Jambi (20,7 %), Kepulauan Riau (17.3 %), Nanggro Aceh Darussalam (17.3 %), dan Riau (15,5%). Endemisitas yang tinggi tersebut sekarang terancam oleh berbagai aktifitas pembangunan. Diidentifikasi pula faktor-faktor yang mengancam kelangsungan hidup ikan-ikan tersebut.

Abstract

Indonesia is rich in fish diversity. It contains nearly 8500 species. 1300 species live in freshwater ecosystem, approximately 45 % of the world’s fish species. Habitat loss is the primary threat to Indonesia’s biological diversity. Remnant natural habitats inside and outside protected areas have come under a variety of unprecedented threats and have suffered severe and likely irreparable degradation. Freshwater ecosystems too have been subjected to intense and destructive pressures. To conserve the richness of fish diversity, more study and scientific information should be created more intense. The systematic collections of the Bogor Zoological Museum provide the scientific information and basic reference material for biodiversity inventory and monitoring in Indonesia. Improving scientific information through better reference collection and through better access to associated, habitat, geographic and environmental data is therefore an integral component of the Indonesia biodiversity conservation strategy. AbstrakIndonesia kaya akan keanekaragaman ikan, terdiri dari 8500 jenis, 1300 jenis hidup di ekosistim air tawar, merupakan 45% dari jumlah jenis global di dunia. Kehilangan habitata adalah ancaman utama bagi kekayaan keanekaragaman hayati Indonesia. Beberapa kawasan alami yang tersisasa, baik di dalam kawasan lindung ataupun di luar, menunjukan kondisi yang mengkhawatirkan, bahkan cenderung tidak dapat dipulihkan. Ekosistim perairan air tawar paling banyak mendapat tekanan. Untuk lebih mengetahui kekayaan keanekaragaman ikan, harus banyak belajar dan mencari informasi ilmiah yang lebih intensif. Koleksi sistematik di Museum Zoologi Bogor menyediakan informasi mengenai materi acuan dasar akan inventaris keanekaragaman dan monitoring di Indonesia. Museum Zoologi berperan aktif dalam menyediakan bahan acuan koleksi ilmiah dan dapat diakses, data lain yang terhimpun berupa data habitat, geografi dan lingkungan. Hal tersebut merupakana suatu komponen yang terintegrasi dari strategi konservasi keanekaragaman hayati Indonesia.

Abstract

During the monetary crisis the natural resources has demonstrates endurance in fishery difficulty. Fisheries sub-sector can play role in the recovery of this crisis and growth of the economy nation. This is caused by the high of fishery potential in the quantity and diversity. The level of utilization up the present just reach 63.49% from the MSY (maximum sustainable yield), i.e 6.4 million for per year. To manage this fisheries resources, scientific information concerning fish biology, the dynamic of fisheries resources and its environment are required. The role of ichthyology is important and this should be know by stake holder and others. AbstrakSelama krisis ekonomi temyata sektor yang berbasis sumberdaya alam telah menunjukkan ketangguhannya dalam menghadapi krisis. Subsektor perikanan dapat berperan dalam pemulihan dan pertumbuhan perekonomian bangsa ini karena potensi sumberdaya ikannya yang besar dalam jumlah maupun keragamannya. Tingkat pemanfaatan baru mencapai 63,49% dari potensi lestarinya sebesar 6,4 juta ton per tahun. Untuk mengelola sumberdaya ikan secara benar dibutuhkan informasi ilmiah menyangkut biologi ikan, dinamika sumberdaya ikan dan lingkungannya. Di sinilah peran iktiologi yang perlu diketahui oleh para stakeholders dan lainnya.

Abstract

In the future, fish supply from aquaculture should be encouraged since its production from capture fisheries nearly reached the level-off condition. Aquaculture is a source of national economic growth and should be developed in such a way so that socially accepted, environmentally sound and competitively advantaged. The condition of aquaculture in Indonesia (in year 2000) is presented in this paper. Independent and dependent factors which influenced feasible aquaculture, and also the levels of technologies of aquaculture based on feed input and environmental modification are also presented as a basic aquaculture technology increase. AbstrakDi masa depan, pasokan hasil perikanan diharapkan berasal dari budidaya lebih besar dibandingkan dari penangkapan. Dengan demikian, budidaya ikan merupakan salah satu sumber pertumbuhan ekonomi yang harus diwujudkan melalui sitem budidaya yang berdaya saing, berkelanjutan dan berkeadilan. Pengembangan budidaya dilakukan baik di perairan tawar, payau dan laut yang keragaannya di tahun 2000 dikemukakan dalam tulisan ini. Faktor-faktor yang mempengaruhi kelayakan budidaya ikan yang terdiri dari faktor independen dan dependen, serta tingkat penerapan teknologi budidaya berdasarkan input pakan dan modifikasi lingkungan dibahas agar dijadikan dasar dalam peningkatan teknologi budidaya perikanan.

Abstract

Study on the spawning aspects of Thynnichthys thynnoides in the floodplain of Kampar Kiri River was conducted from June 2006 to December 2006, using experimental gillnet and trap. Total samples were 852 individuals, comprised 479 individuals from Mentulik (294 males and 185 females) and 373 individuals from Simalinyang (197 males and 176 females). The range of total length was between 94-198 mm for fishes caught from Mentulik and 104-227 mm from Simalinyang. Sex ratio was counted for fishes in QSIIV. Sex ratio is balanced for fish in Mentulik and unbalanced for fish in Simalinyang. The first size of maturity for male in Mentulik and in Simalinyang were 105 and 118 mm; while for female ones were 109 and 108 mm. Presumably, the spawning season is on September-December with the peak spawning in October. Fecundity ranged 781-27135 eggs for fish from Mentulik and 797-35804 eggs from Simalinyang. The Fish is indieaied to be a total spawner.
