    Abstract: The bilih fish Mystacoleucus padangensis did a migration of the lake to the river that empties into the lake to spawn. This study aimed to determine whether migratory fish bilih ate when and what kind of natural foods consumed by bilih fish in it migration habitat. The study was conducted in Naborsahan River, Toba lake, North Sumatra. Sampling was done every 1 hour using Cast net. The results showed that bilih fish keep doing the feeding activity and having diurnal when migrated. The natural food bilih fish in the river and Toba lake was same, it was the phytoplankton of the class Bacilariopiceae. Natural food bilih fish that found in it intestine were phytoplankton include Rhizosolenia, Synedra, Gonatozygon, Closterium, Surirella, Pinnularia, Oscillatroria, Melosira, Gyrosigma, Aulacoseira and Zooplankton among others Creseis, Tubifex and Daphnia. The type of natural food  that  nostly found  in bilih fish intestines were phytoplankton from the genus Synedra Bacilariopiceae with Index of Preporedance (IP) is 97.9 %. Based on the composition of the natural food that was dominated, bilih fish was categorized as the plankton feeder.

    Abstract: Enggano Island is one of the outermost islands of Indonesia. Among the recoverable resources that exist in Enggano Island are coral reef ecosystems. A coral reef ecosystem is also one of the ecosystems with a high level of biodiversity productivity having a major role as habitats, feeding places, and the coastal protection from the crashing of waves and strong currents. Currently, coral reefs are being destroyed either by nature or humans. The ability of an ecosystem to adapt to a disturbance or potential damage is called adaptive capacity. The aim of the study was to assess the adaptive capacity of corals in terms of their health levels to estimate the carrying capacity of marine ecotourism. The observation method used was survey method. Adaptive capacity measurements were carried out by analyzing six parameters: hard coral cover (%), distances from human settlements (km), dominance of lifeform, types of lifeform, reef fish species, and coral reef depth (m). The results of this study showed that Enggano Island corals had the adaptive capacity that fell into two categories: medium and adaptiveEnggano Island is one of the outermost islands of Indonesia.

    Abstract: 〈 p 〉 Perairan Lubuk Lampam merupakan salah satu kawasan lelang lebak lebung yang saat ini masih dikelola oleh masyarakat dan berperan penting sebagai mata pencaharian. Lubuk Lampam memiliki luas + 1.200 ha dan terdiri dari 4 tipe sub ekosistem paparan banjiran antara lain hutan 〈 br / 〉 rawang, lebak kumpai, lebung dan sungai utama. Seperti daerah lainnya di OKI, perairan Lubuk Lampam saat ini juga mengalami tekanan yang besar akibat akitifitas manusia seperti penangkapan yang berlebih dan alih fungsi lahan untuk perkebunan. Saat ini produksi perikanan di Lubuk Lampam mengalami penurunan yang sangat drastis dari 93 ton pada tahun 1997 menjadi 12 ton tahun 2012. Penelitian ini menggunakan data primer dan wawancara langsung dengan nelayan dan selanjutnya dianalisa secara deskriptif. Keanekaragaman dan komposisi jenis ikan juga mengalami perubahan dari waktu ke waktu, tahun 1992 jumlah jenis ikan sebanyak 63 jenis dan tahun 2008 sebanyak 48 jenis, sedangkan tahun 2013 meningkat menjadi 63 jenis. Beberapa ancaman yang dapat merusak sumber daya ikan antara lain, i) alih fungsi lahan untuk perkebunan kelapa sawit, ii) penggunaan alat tangkap yang tidak ramah lingkungan, iii) kurang memperhatikan waktu penangkapan dan iv) penggunaan pestisida. Untuk menjamin keberlanjutan sumber daya perikanan dimasa mendatang diperlukan langkah-langkah pengelolaan sebagai berikut: 1) rehabilitasi habitat Lubuk Lampam yang meliputi hutan rawang, lebak kumpai dan lebung-lebung, 2) Penetapan waktu dan lokasi penangkapan, 3) pengaturan jenis alat tangkap yang diperbolehkan, 4) rehabilitasi kawasan reservat Lebung Proyek, Suak Buayo dan Kapak Hulu dan 5) menerapkan Peraturan Daerah (PERDA) Ogan Komering Ilir (OKI) No. 9/2008 tentang Pengelolaan Lebak, Lebung, dan Sungai. 〈 /p 〉 〈 p 〉 Lubuk Lampam floodplain is one of the lebak lebung auction region has been managed by local community and plays an important role as a livelihood. Lubuk Lampam has an area of 1.200 ha and consist four type of sub ecosystem such as wet forest (rawang), swampy area (lebak kumpai), deep pool (lebung), main river (sungai utama). As with other areas in Ogan Komering Ilir, Lubuk Lampam area is experiencing great pressure due to human activity such as over fishing and land convertion to 〈 br / 〉 be palm oil plantation. Current fishery production in Lubuk Lampam decreased drastically from 93 tons (1997) to 12 tons (2012). This study used primary data and direct interviews with fishermen and subsequently analyzed descriptively. Diversity and species composition also changed over time. The number of species was 63 species in 1992 then decreased 48 species in 2008, while in 2013, increased to be 63 species. Some threats that can damage fish resources, such as i) land conversion for oil palm plantations, ii) destructive fishing, iii) lack of attention to the time of fishing and iv) utilizing pesticides. To ensure the future sustainability of fisheries management are required as follows: 1) habitat rehabilitation of Lubuk Lampam covering wet forest, swampy area, deep pool and main river, 2) Determination of the time and location of fishing, 3) arrangement the type of fishing gear is allowed, 4) rehabilitation of Lebung proyek reserves, Suak Buayo and Kapak Hulu and 5) implementing of local regulation of Ogan Komering Ilir (OKI) No. 9/2008 about the Management of Lebak, Lebung, and river. 〈 /p 〉

    Abstract: Ikan bilih (Mystacoleucus padangensis) merupakan salah satu ikan dari famili cyprinidae yang melakukan ruaya pemijahan dari danau menuju sungai. Habitat pemijahan dan asuhanikan bilih perlu dikaji sebelum melakukan upaya pemulihan kembali ikan bilih di Danau Toba. Tujuan penelitian ini adalah untuk mengetahui habitat pemijahan dan habitat asuhan ikan bilih. Habitat pemijahan ditentukan berdasarkan jumlah ikan matang gonad dan habitat asuhan diidentifikasi berdasarkan keberadaan juvenil ikan bilih di Sungai Naborsahan, Danau Toba Sumatera Utara. Pengambilan sampel ikan bulanan (April 2013 sampai Mei 2014) dilakukan di enam stasiun yang ditentukan berdasarkan karakteristik sungai dan habitat ikan bilih. Ikan bilih matang gonad (siap mijah) dapat ditemukan di semua stasiun penelitian. Seluruh lokasi penelitian merupakan habitat pemijahan ikan bilih. Juvenil ikan bilih hanya ditemukan di stasiun 3, 4, 5 dan 6. Oleh karena itu, diduga stasiun 1 dan 2 merupakan daerah pemijahan bagi ikan bilih sedangkan stasiun 3, 4, 5, dan 6 merupakan daerah pemijahan sekaligus juga daerah asuhan ikan bilih.Bilih fish (Mystacoleucus padangensis) is a species of the Cyprinidae family that have migration pattern from the lake to the river for spawning purpose. Spawning and nursery ground of bilih fish needs to be assessed before making a recovery effort of bilih fish in Lake Toba. The purpose of this study was to determine the nursery and spawning ground of bilih fish. Spawning ground is determined based on the number of mature gonad fishes and the nursery ground identified based on the presence of juvenile fishes in the Naborsahan River, Toba Lake, North Sumatra. The montly samples (April 2013 to May 2014) were collected from six stations that was determined based on the characteristics of the river and bilih fish habitat . The results showed that the mature gonad fish can be found at all research stations. The entire study sites are spawning habitat of bilih fish. The juvenile  was found at the stations 3, 4, 5 and 6. This phenomena suggests that the stations 1 and 2 possibly were only a spawning ground while the stations 3, 4, 5, and 6 were both the spawning and nursery ground of bilih fish.

    Abstract: Ikan betok (Anabas testudineus) adalah salah satu jenis ikan ekonomis penting yang dihasilkan dari perairan paparan banjiran. Penelitian yang bertujuan untuk mengkaji beberapa aspek biologi reproduksi ikan betok di paparan banjiran Lubuk Lampam, Kabupaten Ogan Komering Ilir dilakukan pada bulan Nopember 2012-Oktober 2013. Sampel ikan ditangkap setiap bulanmenggunakan alat tangkap jaring dan bengkirai.Analisis data meliputi sebaran frekuensi ukuran panjang, nisbah kelamin, tingkat kematangan gonad, indeks kematangan gonad, ukuran pertamakali matang gonad, potensi reproduksi dan pola reproduksi. Jumlah sampel ikan betok yang diperoleh sebanyak 540 ekor, terdiri dari 187 ekor ikan jantan dan 353 ekor ikan betina, dengan kisaran panjang ikan betina antara 27-224 mm dan ikan jantan antara 48-243 mm. Rasio kelamin ikan jantan dan betina adalah 0,53 : 1. Tingkat kematangan gonad (TKG) ikan jantan dan betina yang paling banyak ditemui adalah TKG I dengan frekuensi tertinggi pada ukuran 116-132 mm dan 114-129 mmmasing-masing berjumlah 34 dan 33 ekor. Perkembangan tingkat kematangan gonad ikan betok dipengaruhi oleh perubahan tinggimuka air secara musiman. Indek kematangan gonad ikan jantan pada TKGIV berkisar 1,3-15,0%dan ikan betina berkisar antara 1,2 17,1%. Ukuran pertama kali matang gonad ikan betina adalah pada panjang total 160 mm dan ikan jantan pada panjang total 177 mm. Fekunditas ikan betok berkisar antara 224–182.736 butir dengan diameter telur berkisar antara 0,465-1,026 mmdengan pola pemijahan secara sebagian. Climbing perch, Anabas testudineus is a dominant commercial fish inhabit floodplain area of Lubuk Lampam, Ogan Komering Ilir Regency. A study aimed to investigate some aspects of the reproductive biology of climbing perch has been conducted at floodplain of Lubuk Lampam, Ogan Komering Ilir regency from November 2012 to October 2013. Fish sampling was conducted every month using nets and bamboo trap. The data analysis includes lenght frequency distribution, sex ratio, the gonado maturity, gonado somatic index, the size at first maturity, fecundity and reproductive patterns. Climbing perch sample amounted of 540 specimen compose of 187 males and 353 females, with the lenght frequency between 27-224 mm (female) and 48-243 mm (male). Sex ratio of the male and female of the climbing perch was 0,53 : 1. The gonado maturity of male and female are mostly at the first level with the highest frequency between 116-132 mm and 114-129 mm, equivalent to 34 and 33 specimen, respectively. The development of gonado maturity of climbing perch was influenced by seasonally of water level fluctuation. Gonado somatic index of maturity of male and female range 1.3-15.0% and 1.2 -17.1%, respectively. The size at the first maturity of the female was 160 mm lenght and of the male was 177 mm lenght. The fecundity ranges 224 to182,736 eggs with the egg diameter ranges 0.465-1.026 mm and the climbing perch was classified into partially spawner.
