Abstract

This experiment was conducted to determine the effect of alkalinity on the survival rate and daily growth rate of Barbodes sp. The fishes were reared in 12 aquariums with four different alkalinity levels 48, 78, 108 and 138 ppm. Each aquarium filled with 10 fish at the average weight of 12.25 to 12.64 g attempt. The treatment lasted for 75 days. During the experiment, the fish were given commercial diet (pellet) with the dose of 5% of biomass weight at the frequency of three times a day. Result of the experiment showed that the survival rate for all treatments was 100%, while the alkalinity which suitable for daily growth rate of the fish was 80 ppm C’aCOr

Abstract

Study was done from May to November 2003 in Mayangan coastal, West Java. Fish samples taken once in a month. Laboratory analysis comprises measuring of total length and body weight; sex determination; and morphological and histological observation of gonad maturity. Total samples is 970 fishes, comprises 528 male, 326 female, and 80 indeterminate sexually. Samples is in the size range 45-208 mm total length and 1.38 - 145.7 grams body weight. Presumably, fish spawn every month with peak spawning in August and it attain first maturity at least 88 mm (male) and 95 mm (female). Gonado somatic index (GSI) of male among 0,0105-3,3021%, while female have GSI among 0,2076-6,0658%. In size range 83-208 mm, fecundity is among 1.496-57.845 eggs, and this value have very close relationship with gonad weight. Observation of frequency distribution of eggs diameter show that fish spawn their eggs all at once (total spawner).

Abstract

The research was conducted in Mayangan coastal, Pamanukan, West Java from June-November 2003. The collected fish are 323 females and 195 males. The fish is carnivorous, euryphagic and bottom feeder. The primary food is crustacean and fishes, the additional is polychaetas, gastropods, pelecypods and sipunculidea. The food quality and quantity are relatively the same between the females and males. The inter class size niche breadth and the sexual food overlap shown the food competition between them happened. But based on the value of condition factor which is relatively stable. The food competition is little, because maybe the food resoueces is enough.

Abstract

The objective of the research is to know the relationship between the altitude and biological aspects of swamp eel. It is expected that the result of the research can be used as basic information for its culture development. Swamp eel sample were collected from many locations at Subang regency, West java eg: Nanggerang (17 m asl), Gunung Sari (43 m asl), Suka Melang (150 m asl), Gunung Tua (400 m asl) and Tambak Mekar (600 m asl) villages during April to Mei 2001. In every sampling sites were measured physical-chemical and biological parameters of water and substrat texture were examined. Biological aspects of swamp eel e.g.: fish abundance, condition factors, maturity index, fecundity and food habits were analysed in laboratory. The result of the research indicated that altitude affected physical, chemical and biological parameters of water and substrate texture. The altitude also influenced the fish abundance, food habits and fecundity of the fish ell.AbstrakTujuan dari penelitian ini adalah untuk mengetahui hubungan antara ketinggian tempat dan aspek-aspek biologi belnt sawah Hasil penelitian ini diharapkan dapat digunakan sebagai informasi dasar untuk pegembangan budidaya Contoli ikan belut sawah ditangkap dari beberapa lokasi di Kabupaten Subang, Jawa Barat yakni di Desa Nanggerang (ketinggian 17 m dpi), Gunung Sari (43 m dpi), Suka Melang (150 m dpi), Gunung Tua (400 m dpi) dan Tambak Mekar (600 m dpi) dari bulan April - Mei 2001. Di setiap lokasi pengambilan contoh diukur parameter-parameter fisika-kimia air dan tekstur substrat. Aspek biologi ikan belnt sawah yang dianalisis adalah kelimpahan, faktor kondisi, indeks kematangan gonad, fekunditas dan kebiasaan makanan. Hasil penelitian menunjukkan bahwa ketinggian tempat mempengaruhi parameter fiskia, kimia dan biologi serta tekstur substrat. Ketinggian tempat juga mempengaruhi kelimpahan, kebiasaaan amakanan dan fekunditas belut sawah.

Abstract

An experiment was conducted to know the effect of stocking density on growth and survival rates of Oreochromis niloticus for eight weeks at the Installation of Research Institute for Inland Fisheries, Depok (West Java). Twelve sheets of 1 x 1 m rearing nets were fixed at 60-70 cm height from the base of pond. Oreochromis niloticus, avereg the initial weight of fish was 2.85 g and reared, were reared at 50, 100, 150 or 200 fish/m2 with three replication in completely randomized design. Each fish results showed that stocking density influenced individual liveweight, and growth and survival rates (P<0.05). The optimum density was 100 fish/m2 with final liveweight of 13.22 g, growth rate of 10.42 g and survival rate of 95.67 %.AbstrakPenelitian dilakukan dengan tujuan untuk mengetahui pengaruh padat penebaran terhadap pertumbuhan dan sintasan ikan nila Gift (Oreochromis niloticus), dilakukan di Instalasi Penelitian Perikanan Air Tawar, Depok (Jawa Barat) selama delapan minggu. Wadah yang digunakan berupa jaring ukuran 1 x 1 m sebanyak 12 buah yang dipasang di kolam dengan ketinggian air sekitar 60-70 cm. Ikan uji adalah ikan nila dengan bobot awal rata-rata 2,85 g/ekor. Digunakan rancangan acak lengkap dengan padat penebaran 50, 100, 150 dan 200 ekor/m2, masing-masing diulang tiga kali. Jenis pakan berupa pelet komersial mengandung 27 % protein diberikan sebanyak 5 % dari bobot biomasa per hari dengan frekuensi dua kali. Hasil penelitian menunjukkan bahwa padat penebaran berpengaruh terhadap bobot mutlak individu, laju pertumbuhan dan sintasan (P<0,05). Padat penebaran optimal adalah 100 ekor/ m2 dengan bobot mtlak rata-rata individu sebesar 13,22 g, pertambahan berat 10,42 g dan sintasan 95,67 %.

Abstract

Study about feeding practice of fire eel (M. erythrotaenia) was carried out at Instalation for Freshwater Fisheries In Depok for tree months. The aim of the study is to knom the effect of feed substitution of life food (Tubifex sp.) which usually used as feeding this fish with artificial food; to the fish growth rate. Twelve aquaria (60x30x40 cm) filled with 40 liters freshwater was used for rearing the fish (5 fishes/aquarium). Prime weight of the fish was about 17-18 grams the treatment or feeding used in every 3 (three) aquaria were: A. 100 % tubifex; B. 75 % tubifex + 25 % pellet; C. 50 % tubifex + 50 % pellet and D. 25 % tubifex + 75 % pellet. Daily feeding was 7 % of body weight, given in three times and calculated by dry weight. The result of this experiment shown that all kind of the substitution can be used to rear this fish without any mortality. However the D treatment was indivated the lowest growth rate compared with the other treatment.AbstrakPenelitian bertujuan untuk mengetahui pengaruh penggantian pakan alarai dengan kombinasi pakan alami dan buatan terhadap pertumbuhan dan sintasan ikan tilan merah. Penelitian dilakukan di Laboratorium Instalasi Penelitian Perikanan Air Tawar Depok selama 3 bulan dengan menggunakan akuarium ukuran 60x30x40 cm diisi air 40 liter, masing-masing 5 ekor setiap wadali. Berat awal ikan 17-18 gram. Pakan yang diberikan cacing Tubifex sp. dan pakan buatan berkadar protein 40 %. Kombinasi pelet dalam perlakuan adalah: A. Pemberian pakan 100 % cacing tubifex; B. Pemberian pakan 75 % cacing tubifex + 25 % pakan buatan; C. Pemberian pakan 50 % cacing tubifex + 50 % pakan buatan dan D. Pemberian pakan 25 % cacing tubifex + 75 % pakan buatan. Jumlah pakan dihitung berdasarkan berat kering sebanyak 7 % BB/hari diberikan 3 kali. Dari hasil penelitian menunjukkan bahwa kombinasi pakan alami cacing tubifex dan pakan buatan berpengaruh nyata (P<0,05) terhadap bobot mutlak individu, Iaju pertumbuhan dan sintasan. Kombinasi pakan masih layak untuk pemeliharaan ikan hias adalah 50 % cacing tubifex + 50 % pelet dengan bobot mutlak 5,75 gram, laju pertumbuhan harian 0,46 % dan sintasan 100 % dengan konversi pakan 4,65.
