AMOUNT AND TYPE OF MICROBES ON THE COMMON CARP (Cyprinus carpio) IN JATILUHUR RESERVOIR WEST JAVA

This research was conducted in Microbiology Laboratory of Biology Department, Faculty of Mathematics and Natural Sciences, Padjadjaran University in May 2017. The purpose of the research was to identify the number and types of microbes contained in carp (Cyprinus carpio) in Jatiluhur Reservoir, West Java. The method used in this research was sample survey method or field survey. The water and common carp sampling stations are divided into 3 stations, station 1 is located in Zone 1 (low density), station 2 is located in Zone 3 (medium density), and station 3 is located in Zone 5 (high density). Determination of sampling location water and fish is done based on Data Recapitulation of Density of Karamba Floating Net from the Department of Animal Husbandry and Fisheries of West Java.Water samples and fish mucus were tested using Total Plate Count (TPC) method using different specific media that is Trypticase Soy Agar (TSA), deMann Ragosa Sharpe Agar (MRSA), Kliger Iron Agaar (KIA), Thiosulphate Citrate Bile salts Sucrose Agar (TCBS), and Xylose Lysine Deoxycholate (XLD). Microbes can be known by species because they just grown on specific media that can directly showed the specific characteristics of certain microbial species based on the color of the colony. The parameter observed were microbiological test (TPC). The result of the research showed that there was Bacillus sp, Escherichia coli, Lactobacillus sp, Vibrio cholerae, Vibrio parahemoliticus, Vibrio spp, dan Shigella sp on the water samples and carp mucus. The result of research on water samples and fishery products in Jatiluhur Reservoir showed that water quality in Zone 1, Zone 3, and Zone 5 is still below the threshold of microbial contamination based on SNI 7388: 2009, while fish located in Zone 3 and Zone 5 is contaminated by Escherecia coli and Vibrio cholerae, exceed the threshold of SNI 7388: 2009 on microbial contamination in fresh fish.

Carp Cyprinus Carpio

ABSTRACTSince early 1980s, freshwater fish farming was introduced as an economic activity to the rural community in Subang, West Java Province. Until presently, 5% of the population participate on it, specifically as common carp (Cyprinus carpio) cultivators in freshwater ponds ecosystem. The economic gain from the carp farming triggers vast development indicated by significant landscape conversion from rice fields to fish ponds. Environmental limitation does not seem to become their major concern, because good yields which means good income is their main driving factor to extend and intensify common carp aquaculture. Recognizing the important role of small scale fish farms in West Java common carp production system, we explore their resiliency in confronting challenges encountered in managing the freshwater ecosystem. Utilizing participatory observation and interview, we explore their socio-ecological resilience from the perception of human and nature interaction. The study area is Pagaden Sub District in Subang - West Java. Descriptive analysis is used to articulate the phenomenon enfolded in a socio-ecological framework of thinking. It can be concluded that high dependency to the aquaculture activity, has reached a situation in which ecologically sound technology should be introduced. Included in a scheme of technical assistance which specifically designed to meet the need and in harmony with the socio-cultural characters of small-scale fish farmers, the technology introduction should be carried out to spur the sustainable aquaculture in Subang West Java. This should be a proposed agenda for the local government in support to aquaculture sustainable development.ABSTRAKSejak awal tahun 1980, budidaya ikan air tawar diperkenalkan sebagai kegiatan ekonomi masyarakat desa di wilayah Subang, Propinsi Jawa Barat. Dewasa ini, sekitar 5% populasi terlibat di kegiatan tersebut, terutama sebagai pembudidaya ikan mas (Cyprinus carpio) di ekosistem kolam air tawar. Pendapatan yang diperoleh dari kegiatan budidaya ikan mas telah memicu terjadinya percepatan laju pembangunan yaitu dengan adanya perubahan lansekap dari petak-petak sawah menjadi kolam-kolam ikan. Keterbatasan lingkungan tampaknya tidak dipertimbangkan, karena hasil panen yang tinggi atau keuntungan usaha menjadi tujuan pokok perluasan atau pun intensifikasi kegiatan budidaya ikan mas. Mengingat peran penting pembudidaya ikan skala kecil di rantai produksi ikan mas di Jawa Barat, kami melakukan kajian terhadap daya lenting mereka dalam menghadapi tantangan mengelola ekosistem budidaya ikan air tawar. Dengan memanfaatkan metoda pengamatan-partisipatif dan wawancara mendalam, data dan informasi dari para pelaku budidaya ikan mas skala kecil di Kecamatan Pagaden Kabupaten Subang Jawa Barat ditelusur. Analisis data dilakukan secara deskriptif untuk memberikan ruang artikulatif dalam mengurai fenomena lapangan yang dirangkum dalam kerangka pikir sosio-ekologi. Dapat disimpulkan bahwa meskipun mereka memiliki kearifan lokal tersendiri dalam membudidayakan ikan mas di kolam air tawar, ketergantungan yang tinggi pada kegiatan akuakultur ikan mas, telah sampai pada situasi diperlukannya pengenalan teknologi budidaya yang ramah lingkungan. Pengenalan teknologi tersebut seyogyanya disertai strategi pendampingan yang sesuai dengan kebutuhan dan karakter sosial-budaya para pembudidaya ikan mas skala kecil. Hal ini perlu dijadikan agenda pemerintah daerah untuk diterapkan demi keberlanjutan pengelolaan ekosistem akuakultur di Subang – Jawa Barat.

The experiment was done to find out species, intensity and prevalence of common crap fry from traditional ponds and "longyam" at Sukamulya village, Singaparna, Tasikmalaya. This experiment was conducted at Sukamulya village and Aquatic Biology Laboratory of Fisheries Department, Faculty of Agriculture, Padjajaran University form October 1st 2002 to October 31th 2002. Samples of common carp fry were obtained from six traditional ponds and six "longyam". The survey method was used in this experiment of common carp fry at difference type of pond were based on the Wilcoxon rank sum test. Intensity and prevalence of ectoparasites of common carp fry at traditional ponds and longyam was based on the Kruskal-Wallis test. The result of this experiment showed that eight genera of ectoparasites were found, consisted of three Platyhelminthes: Dactylogyrus (47,01%), Gryrodactylus (3,84%), Transversotrema (0,01%), four Protozoa: Ichtyophthrius (9,59%), Epistylis (1,05%), Trichodina (1,68%) and one Arthopoda: Acarus (0,01%), The intensity of Dactylogyrus was 28,83. Gryrodactylus 4.98, Transversotrema 0,17, Ichthyophthirius 13,51, Epistylis 4,68, Trichodina 25,14 Trichodinella 6,55 and Acarus 0,17. The prevalence of Dactylogyrus is 90,00% Gyrodactylus 44,82%, Transversotrema 0,37%, Ichthyophthirius 42,17, Epistylis 13,17%, Trichodina 82,59%, Trichodinella 17,04 and Acarus 0,37%.
