Abstract

Fish fauna exploration al Cimanuk River was conducted from June 1999 up to January 2000. Two months interval of sampling were done at the three segments of the river (the upper stream = Garut area, the middle stream = Sumedang area and the down stream = Indramayu area). About 40 species of 20 families, were recorded. The fish fauna were dominated by species belongs to Cyprinidae, and Rasbora laterisiriata found in the three segments. Each segment has different number of species. The existing fish were potential to be developed as fish food and ornamental species for aquarium. ABSTRAKUpaya untuk mendapatkan informasi tentang kcragaman jenis ikan di Sungai Cimanuk dilakukan antara Bulan Juni 1999 dan Januari 2000 dengan pengambilan contoh selang dua bulan, Sungai Cimanuk dibagi menjadi tiga segmen sungai yaitu hulu (Garut). tengah (Sumedang). dan hilir (Indramayu). Selama penelitian ditemukan ikan sebanyak 40 jenis yang tercakup di dalam 20 famili. Famili Cyprinidae mempunyai spesies yang paling banyak ditemukan. Satu-satunya spesies/jenis ikan yang ditemukan di tiga segmen sungai ialah ikan paray (Rasbora laterisiriata). Jumlah jenis ikan pada masing-masing segmen sungai tidak merata. Ikan di sungai Cimanuk dapat dikembangkan sebagai ikan konsumsi dan ikan hias.

Abstract

The research was conducted in Labuan Bay, Banten from April - June 1999. The fish sample was collected once in every five days. The total fish collected were 483 with 75 - 265 mm of total length and 4.85 - 169.81 grams in weight. Sexual composition was 252 male, 183 female, and 48 of the ambiguous sex. The fish sample was divided into 4 groups of total length (small, medium, and extra large). The medium size was 124 -171 mm) was the most number of the sample (248). According to length weight relationship the growth pattern of the fish was negative allometric. Condition factor of the fish was increased from small to medium size. While the biggest size (extra large) the condition as decreased. This phenomenon maybe because a lot of their gonad were in atresia, A lot of the condition of food material was destructed and impossible to be identified. The female primarily consumed shrimp and squilla. The male feed on shrimp, crab, and fish. According to the time-series of sampling the shrimp had primer index, and the second crab, the third was fish.ABSTRAKPola pertumbuhan ikan kurisi termasuk allometrik negatip. Faktor kondisi kian besar dengan semakin panjang ukuran ikan Ikan kurisi termasuk kedalam kelompok karnivor, dengan makanan utamanya udang. Ikan betina mengkonsumsi terutama udang dan squilla, sedangkan ikan jantan mengkonsumsi udang, kepiting, dan ikan. Tidak ada perubahan jenis maupun IP makanan ikan kurisi berdasarkan waktu. Semakin panjang ukurannya, ikan kurisi semakin mengkonsumsi ikan sebagai makanannya.

Abstract

The ichthyological study was conducted in Mendalam river system on 6 May to 24 May 1998 in Mendalam River and 21 its tributaries, a sub river system of Kapuas River Basin. These were included in 44 sampling stations. This work conducted in conjunction with the establishment and management of Betung Kerihun National Park collected 69 fishes species. These belong to 12 familia, 39 genera and 5 ordo. The most common fishes were those belonging to Cyprinidae (47.88%), Balitoridae (14.08%) dan Cobitidae (12,67%). At least eleven species endemic to Borneo were found. They are Garra borneensis, Grynocheihisptistulosus, Hampala bimaculata, Homaloptera stephensoni, Neogastrotnvzon niewenliitisi, N. pauciradiatus, Osphronemus septemfasciatus, Paracrossocliilus acerus, Rasbora vo/lzi, Acrochordonichthys chameleon, and Gastromyzon embalohensis. Most of the fishes found constitute ornamental and consummed fishes, which are economically important. ABSTRAKPengamatan fauna ikan di Daerah Aliran Sungai (DAS) Mendalam telah dilakukan selama 18 hari (dari tanggal 6 Mei sampai tanggal 24 Mei 1998) di DAS Mendalam dan 21 anak sungainya yang merupakan salah satu sub DAS Kapuas.

Abstract

Study on the stomach contents of some puffer fishes (Tetraodon reticularis, T. fluviatilis, T. lunaris) was done from March 2000 to April 2001 in Ujung Pangkah Waters, East Java. Samples were collected monthly using gill net mesh sized of 2.5 and 4.5 cm. Stomach content was preserved by formalin 10% and observed under microscope (50 magnification). Analysis was carried out to estimate Index of Stomach content (ISC) and Index of Preponderance (IP). The result showed that main food of male Tetraodon reticularis was Balamis sp.. suplemen food was bivalva and debris, and additional food, gastropods and crab. While main food of female fish was Balamis sp., suplemen food w'as debris and bivalve, and additional food was shrimp, crab, and gastropoda. Main food of male T. fluviatilis was Balamis sp., suplemen food was gastropoda, additional food was shrimp, bivalve, fish and green mussel. While for female fish, the main food was Balamis sp., suplemen food was bivalve and shrimp, and additional food was gastropoda, crab, fish and bivalve. Main food of male T. lunaris was fish, suplemen food was bivalve, shrimp and gastropoda, and additional food was Balanus sp., crab, green mussel and unidentified organisms. While main food of female fish was fish, suplemen food was shrimp and bivalva, and additional food was Balanus sp., crab, gastropoda and unidentified organisms. The ISC seems on August (male) and September (female) for T. reticulates, on April (male) and May (female) for T. fluviatilis, and on April (male) and December (female) for T. lunaris. ABSTRAKPengamatan terhadap isi lambung beberapa jenis ikan buntal (Tetraodon reticularis, T. fluviatilis, T. lunaris) dilakukan sejak Maret 2000 sampai April 2001 di perairan Ujung Pangkah, Jawa Timur. Sampel ikan ditangkap per bulan dengan menggunakan gill net (mata jaring 2,5 dan 4,5 cm). Isi lambung diawet dengan formalin dan diamati di laboratorium. Analisis dilakukan untuk menentukan indeks isi lambung (ISC) dan indeks bagian terbesar (IP). Hasil pengamatan didapatkan bahwa jenis Tetraodon reticularis jantan memiliki makanan utama berupa Balanus sp., makanan pelengkap berupa bivalva, serasah, dan an makanan tambahan berupa ikan, gastropoda dan kepiting. Sedangkan untuk ikan betina, makanan utama berupa Balanus sp., makanan pelengkap berupa serasah dan bivalve, dan makanan tambahan berupa udang, kepiting dan gastropoda. T. fluviatilis jantan memiliki makanan utama berupa Balanus sp., makanan pelengkap berupa gastropoda, makanan tambahan berupa udang, bivalve dan ikan. Sedangkan untuk ikan betina makanan utamanya berupa Balanus sp., makanan tambahan berupa bivalve dan udang, dan makanan pelengkap berupa gastropoda, kepiting, ikan dan bivalve. T. lunaris jantan makanan utamanya berupa ikan, makanan pelengkap berupa bivalve, udang dan gastropoda, dan makanan tambahannya berupa Balanus sp., kepiting, bivalve dan organisme tak teridentifikasi. Sedangkan untuk jenis ikan betina memiliki makanan utama berupa ikan, makanan pelengkap berupa udarrg dan bivalve, dan makanan tambahannya berupa Balamis sp., kepiting, gastropoda dan organisma tak teridentifikasi. T. reticulates terlihat memiliki ISC yang lebih tinggi pada bulan Agustus (Jantan) dan September (betina), T. fluviatilis pada bulan April (jantan) dan Mei (betina), dan T. lunaris pada bulan April (jantan) dan Desember (betina).

Abstract

The research was conducted in Labuan Bay Banten from April to June 1999. The number offish were 282, 120 males and 212 females. The sex ratio was 1: 1, 25. The samples were dominated by fish of length 90 - 170 mm. The fish mature gonad of the male was predicted at 120 mm and the female was 125 mm in length. Their fecundity ranged BETWEEN 19.116 - 89.344 according to distribution. According to distribution of egg diameter, the fish was total spawner. The fish growth was isometric and it was carnivore which fish and shrimp as main food. ABSTRAKPenelitian dilakukan di teluk Banten dari bulan April-Juni 1999.

Ikan dengan panjang 99 -170 mm mendominasi hasil tangkapan. Ikan jantan diduga pertama kali matang gonad pada ukuran 120 mm dan ikan betina pada ukuran panjang 125 mm. Fekunditas ikan biji nangka berkisar antara 19.116-89.344 butir. Ikan mempunyai sifat pemijahan total. Pertumbuhan ikan bersifat isometrik.
