Abstract

This research aimed to identify types of bacteria existed in nursery rearing pond of catfish (Clarias gariepinus) using closed water system. The observed data include bacterial abundance and diversity in the water and in the fish digestion system, fish growth and water quality. This research was performed in the media of 3 concrete pools with the size of 3 x 1 x 0.8 m3 containing fish stock spreading of 3000 tail / pond. The obtained results showed that the highest abundance of bacteria was found in the surface and the bottom of pond C with the abundance number of   3,0 x 104and 1,2 x 103for aerobic and anaerobic bacteria, respectively. Moreover, it was figured that the dominant bacterial species found in the water and the gastrointestinal tract were from the genus of Bacillus, Clostridium and Lactobacillus. Meanwhile, water quality in the pond was observed in the normal range with the temperatures of 28 - 30 oC, pH (6.0 - 7.0), DO (4.5 - 5.7 ppm), ammonia (0.06 - 0.03 ppm), nitrite (0 ppm) and nitrate (0 - 5 ppm). Keywords: Type of bacteria, catfish (Clarias gariepinus), Closed water system.

Abstract

One disease that often attacts fish is a group of parasites or parasitic diseases, parasites are not only dangerous because they are related to their activities, but also trigger the emergence of other pathogenic organisms and cause infections. Therefore, it is necessary to take fish quarantine measures to prevent the spread of diseases carried out by fish quarantine centers. This study was conducted to determine the type of parasite that infested fish samples and determine the prevalence and intensity of fish samples. A total of 48 sample fish consisting of freshwater and seawater fish were analyzed in the laboratory of Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Surabaya II during December - January 2019, either directly or directly (ectoparasites and endoparasites). Parasitic identification was carried out visually and microscopically with an approach based on identification books. The types of parasites that we found during the study consisted of Argulus sp, Trichodina sp, Anisakis sp., Gnathostoma spinigerum, and Gnathostoma spinigerum. The highest prevalence in Scomber Scombrus with Anisakis sp. Amounting  to 77.8%, mean while, the lowest prevalence and the intensity is found in Thunnus sp. The prevalence and intensity of parasites are influenced by water quality and pollution.

Abstract

Detriment caused by ectoparasitic infestation was not as big detriment caused by infestation of other organisms such as viruses and bacteria, but it could be a predisposing factor for the infection of more dangerous pathogenic in fish. The aims of this study was to inventory ectoparasites that infecting freshwater fish cultivated in several districts in the Banyuwangi, in which the results were expected to be used as a reference in an effort to prevent the spread of disease in fish culture. The sample of research consisted of tilapia fish, carp and catfish which were obtained from six sub districts in Banyuwangi, those were Kota, Kabat, Licin, Kalipuro, Giri, and Glagah. The ectoparasite examination method was performed naturally by scraping the surface of the body, fins and gills of the fish, then observed under a microscope with magnification ranging from 40 to 400x. The results of further observations were documented and identified by key identification. Ectoparasites which were found infesting freshwater fish in the city of Banyuwangi consisted of 4 genuses: namely Argulus, Lernaea, Chonopeltis and Trichodina. Further research is needed to determine the prevalence and intensity of ectoparasites in order to prevent the spread of ectoparasites in other regions. Keywords: Inventarisation, ectoparasites, freshwater fish, Banyuwangi

Abstract

The study aimed to determine the type of culture container for increasing the cell density of Nitzschia and producing the hightly cell biomass. The stages of this study were sterilization of containers and media, making diatom fertilizers and agar media, culture of Nitzschia in agar medium, culture of Nitzschia in test tube, and culture of Nitzschia in glass and plastic containers. The result showed that the cell density of Nitzschia cultured in the glass container was higher than plastic containers. Further study was needed to determine the nutrient composition of Nitzschia that culture in glass containers.Keyword : Nitzschia culture, Laboratory scale, Glass, Plastic container.

Abstract

The potential of freshwater fish cultivation in Indonesia is very large and is increasing every year. The high potential of freshwater and ornamental fisheries commodities and consumption must be developed through domestic and export marketing. The distribution carries the risk of entering and spreading fish pests and diseases, so is it required identification or quarantine is needed to avoid negative impacts from the distribution of fishery commodities. One of the infectious diseases which is known to attack fishery commodities in Indonesia is bacterial disease. Bacteria can cause high mortality in fish and loss for farmers. The purpose of this study is to identification bacteria in freshwater fish commodities. The study was conducted in December 2018 - January 2019 at the Fish Quarantine Center, Quality Control and Safety of Fisheries Products in Surabaya I. Identification of bacteria in this study using conventional methods. The parameters observed were external clinical symptoms that appeared on the body of the fish and internal pathology. The material examined in this study were The samples examined during Field Work Practices were Goldfish, Catfish fry, Common carp, and Koi fish with a total of 64 samples. This research was observative, then the data obtained were analyzed descriptively. The Result bacteria identified in freshwater fish commodities from 64 samples were dominated by Aeromonas hydrophila, Pseudomonas anguilliseptica, Streptococcus sp., Plesiomonas shigelloides, and Micrococcus sp.Keywords : Freshwater fisheries commodities, Bacteria, The Conventional Method
