Fekunditas Dan Produksi Larva Padaikan Cupang (Betta Splendens Regan) Yang Berbeda Umur Dan Pakan Alaminya [the Fecundity and Juveniles Products of Fighting Fish (Betta Splendens Regan) with Different Age and Natural Food]

Ikan cupang (Betta splendens Regan) merupakan ikan hias bernilai ekonomis tinggi, karena keindahan warna dan naluri berkelahinya. Dalam perkembangbiakanya pakan memegang peranan penting yang terkait dengan fekunditas dan produksi larva. Penelitian ini bertujuan untuk mengetahui umur yang tepat bagi induk cupang untuk dipijahkan serta pengaruh berbagai jenis pakan alarm (Daphnia, Tubifek dan jentik nyamuk) terhadap tingkat fekunditas dan produksi larva. Penelitian dilaksanakan di Instalansi Penelitian Perikanan Air Tawar, Depok dari bulan Agustus sampai Oktober 2000. Metode yang dipergunakan adalah pemberian makan secara ad libitum dengan 90 ekor induk jantan dan 90 ekor betina dengan umur 3-4 bulan. Hasil yang diperoleh dianalisa dengan program SPSS versi 10 menunjukkan bahwa umur dan pakan alami yang memberikan hasil (fekunditas dan produksi larva) paling baik ialah umur 4 bulan dengan pakan Daphnia

Aspek Reproduksi Ikan Paray (Rasbora Aprotaenia) Dibeberapa Sungai Kawasan Taman Nasional Gunung Halimun [Reproductive Aspects of Paray Fish (Rasbora Aprotaenia) in Some Rivers of the Gunung Halimun National Park]

Paray, Rasbora aprotaenia is an endemic fish whose distribution is limited in Java. Degradation of its habitat is fear to result in the extinction of this fish. The objective of this study was to reveal reproduction aspect of paray in some rivers originating in the Gunung Halimun National Park. The specimens that were used in this study were part of the specimens which were collected from S.Cikaniki, S.Cikancra, S.Citaradje, S.Cimadur dan S.Cisimeut. Aspects of the reproduction covering the description of the Level of Gonadal Maturity (TKG), the Index of Gonadal Maturity (IKG) and the Fecundity. The result of the study indicated that the pattern of growth of this fish was allometric positive, and the value of condition factor was relatively high ranging from 1.63 to 2.11. Index of Gonadal Maturity (IKG) was relatively high: 12.20 -22.46% for male, and 10.47 -13.48 % for female. Fecundity range 647-3512 eggs. The result of the regression analysis showed that there were significant correlation (P <0.05) between the ovary weight and the egg number, and between the Index of Gonadal Maturity (IKG) and fecundity of the fishes sampled from the observed rivers

Fauna Ikan Di Sungai Cimadur, Ciujung Dan Ciberangdi Sekitar Taman Nasional Gunung Halimun, Kabupaten Lebak, Banten*[fish Fauna of Cimadur, Ciujung and Ciberang River, Gunung Halimun National Park, Lebak, Banten]

Fish fauna survey were conducted in Cimadur, Ciujung and Ciberang Rivers. From these studies six fishes species were found as additional record for fishes living in Gunung Halimun National Park and its adjacent area. This finding brings the fish species living at this park to be sixty.In this record, it includes Cypriniid fishes that attain large size: Barbodes balleroides and Osteochilus hasseltii, found in the segment of the middle of R. Ciujung (18.3 m asl)

Tingkat Prevalensi Escherichia Coli Dalam Daging Ayam Beku yang Dilalulintaskan Melalui Pelabuhan Penyeberangan Merak

The aimed of this study was to determine prevalence of Escherichia coli in frozen chicken meat transported through Merak port. The samples were taken from DKI Jakarta (16 samples), Bekasi (11 samples), Bogor (8 samples), and Serang (18 samples). The average number of E. coli in frozen chicken meat from DKI Jakarta was 0.43x101±0.28x101 MPN/g, Bekasi was 10.4x101 ±33.04x101 MPN/g, Bogor was 0.28x101 ±0.23x101 MPN/g, and Serang was 6.72x101±25.79x101 MPN/g. Based on the result of ANOVA, the four areas had no significance in diferrence (p&gt;0.05). The conclusion of this study showed that the average number of E. coli from Bekasi and Serang were over the maximum limit of microbial contamination as permitted by SNI 01-7388-2009 (1x101 MPN/g), whereas DKI Jakarta and Bogor were under the maximum limit. The prevalence of E. coli in frozen chicken meat from DKI Jakarta was 31.25°/o, Bekasi 31.25°/o, Bogor 27.27°/o, and Serang was 27.78°/o
