Common carp is one of consumption fish that has delicious meat, high pritein level, and easy in farming. The serious problem in common carp farming is koi herpesvirus infection. Onion extract potency to improve immune system was estimated to prevent disease infection. The testing of the garlic extract through food could be used as efforts to increase endurance of common carp fish Cyprinus carpio to koi herpesvirus infection that was considered from blood parameter. Fish that was used was measuring 9-11 cm with the treatment of food containing 30, 50, and 70 gr/100 ml onion extract. Fish was acclimated for seven days in 60×30×30 cm3 aquarium before used. Garlic extract diet in food gave increasing of fish immune system that was infected by koi herpesvirus. The increased of leucocytes of blood fish with onion extract diet was faster than possitive control. The dose of B treatment (50 gr/100 ml) was the best dose gave short incubation periode comparing other treatment. Survival rate (SR) of this B treatment was highest, i.e. 91.7%, while survival rate of negative control was 50%. Key word: common carp, Cyprinus carpio, onion, Allium sativum, koi herpesvirus ABSTRAK Salah satu jenis ikan konsumsi air tawar yang banyak digemari oleh masyarakat adalah ikan mas Cyprinus carpio karena rasa dagingnya gurih, memiliki kadar protein tinggi dan cukup mudah dalam pemeliharaannya. Permasalahan yang muncul saat ini adalah wabah Koi Herpes Virus (KHV). Potensi ekstrak bawang putih sebagai anti mikroba spektrum luas, diduga dapat mengobati dan mencegah penyakit ikan. Pengujian bawang putih secara in vivo melalui pakan dapat digunakan sebagai upaya untuk meningkatkan ketahanan tubuh ikan mas Cyprinus carpio terhadap infeksi penyakit KHV yang ditinjau dari gambaran darahnya. Ikan uji yang digunakan adalah ikan mas berukuran 9-11 cm dengan perlakuan pakan yang mengandung bawang putih sebanyak 30, 50, dan 70 gr/100 ml. Sebelum dilakukan penelitian ikan diadaptasikan selama 7 hari pada akuarium berukuran 60×30×30 cm3. Hasil penelitian menunjukan bahwa ekstrak bawang putih efektif untuk meningkatkan ketahanan tubuh ikan mas Cyprinus carpio yang diinfeksi oleh Koi Herpes Virus (KHV). Pengamatan gambaran darah ikan yang terinfeksi KHV setelah pemberian ekstrak bawang putih selama 30 hari dapat meningkatkan jumlah leukosit lebih cepat dibandingkan dengan perlakuan kontrol positif. Peningkatan jumlah limfosit dalam darah mampu meningkatkan pertahanan tubuh. Peningkatan jumlah leukosit ditunjukkan dengan meningkatnya jumlah limfosit dan penurunan jumlah monosit. Perlakuan B (50 gr/100 ml) merupakan dosis yang paling baik karena masa inkubasi KHV terlewati lebih cepat dibanding perlakuan lain yang ditandai dengan penurunan jumlah leukositnya. Hal ini didukung oleh gejala klinis yang ringan dibandingkan kontrol positif dan tingkat kelangsungan hidup yang tinggi sebesar 91,7%. Sedangkan pada kontrol negatif kelangsungan hidupnya sebesar 50%. Kata kunci: ikan mas, Cyprinus carpio, bawang putih, Allium sativum, KHV dan Herpes

Injury of fish caused by handling of fry transportation and harvesting could impact mycosis. Effort on controlling by using chemotherapeutic could impact on pollution of environtment and even carcinogenic effect. One of alternative substances can be used in both preventing and controlling safely is paci-paci, Leucas sp. This method based on phytopharmacy. The aim of this research is to test the prevention of paci-paci leaves extract to mycotic disease . This research used five treatments: possitive control; the doses of paci-paci extract were 0 gr/l (negative control); 0.5 gr/l; 1 gr/l and 1.5 gr/l by using the gurami, Osphronemus gouramy Lac. That was measuring 7-9 cm. The method that was used is the short-term submersion (short baths) for 24 hours. Paci-paci extract can reduced the fungal infection and hindered the growth of Saprolegnia sp. colonies. Descriptively, the paci-paci extract (the treatment of the extract 0.5 gr/l; 1 gr/l; 1.5 gr/l) could prevent the Saprolegnia sp. infection with the successive prevalence 33.3 %; 22.2 %; 0 %.

Publisher : Indonesian Society of Scientific Aquaculture (ISSA)

Ectoparasitic monogenean infestation is one of fish diseases which may cause mass mortality, therefore controlling the parasites is one of the important factors to ensure the success of aquaculture activities. Salt addition is one of disease curative and controlling techniques which is cheap, easy and environmental friendly as well as effective to control ectoparasites in freshwater environment. The objectives of this study were to examine monogenean parasites species in GIFT (Genetically Improved Farmed Tilapia) tilapia, their tolerance to salt concentration and the most effective salt concentration to control the parasites. Identification, intensity and prevalence of parasitic monogenean were carried out on the external parts (body surface, fins and gills) of 31 fishes. Subsequently, two different experiments were carried out to determine parasites and fish resistance on various salt concentration at a range of 0 - 24 g/l with an interval of 2 g/l. To confirm the results of previous experiment, parasites infected fish was immersed in salt water at various concentration based on previous experiments. Two genera of monogenean were identified in GIFT tilapia, i.e. Gyrodactylus sp. on body surface and fins, and Cichlidogyrus sp. on gills with the same prevalence (100%). The intensity of those parasites was different, namely 27.84 ind/fish for Gyrodactylus sp. and 6.06 ind/fish for Cichlidogyrus sp. The intensity of both parasites was found to be lower as salt concentration increase. Salt concentration of 24 g/l was the most effective concentration to reduce parasites infestation and could totally treat the infested fish within 6 days. Keyword : tilapia, Oreochromis, monogenea, parasite and salt ABSTRAK Serangan monogenea ektoparasitik merupakan salah satu masalah penyakit ikan yang dapat menyebabkan kematian masal, sehingga pengendaliannya merupakan salah satu kunci keberhasilan dalam usaha budidaya.

Transportation of fish fry with high density in closed system will reduce levels of O2, increasing CO2 and NH3, will also elevate the fish stress so that increase fish mortality. To reduce the effects of increased CO2 and NH3 can be applied by using zeolite and activated charcoal, while to reduce the fish stress is through the addition of salt. This study aims to determine the dose of salt added into the water containing zeolite and activated charcoal in a closed transportation system with a high fry density for 72 hours. The study was conducted two stages, namely the preliminary study and the primary study. The preliminary study involved the observation of the survival rate of fish fry during fasting, oxygen consumption rate of fish fry, the rate of total ammonia nitrogen (TAN) excretion of fish fry, and the adsorption capacity of TAN by zeolite and activated charcoal. In the primary study, fry transport simulations was carried out for 72 hours in the laboratory. Gourami fry (body length of 4 cm and body weight of 1.7 g) with the fry density of 50 fish/L were placed in the packing bag which has been filled with zeolite as much as 20 g/L and activated charcoal as much as 10 g/L. The study used a completely randomized design with five treatments and two replications: A: blank (without zeolite, activated charcoal, and salt), B: control (20 g/L zeolite+10 g/L activated charcoal), C: 20 g/L zeolite+10 g/L activated charcoal and 1 g/L salt, D: 20 g/L zeolite+10 g/L activated charcoal and 3 g/L of salt, and E: 20 g/ L zeolite+10 g/L activated charcoal and 5 g/L salt. The results of preliminary study showed that the survival rate of fish fry was 100% and active swimming for five days without food, the level of oxygen consumption as much as 1340.28 mgO2, produce NH3 as much as 22.64 mg/L, while zeolite and activated charcoal adsorbs >50% of TAN in time of 120 seconds. In the primary study, the survival rate of fish fry during the 72-hour transportation for treatments A, B, C, D, and E, were 0%, 57%, 59%, 65% and 74%, respectively. Treatment E with survival rate of 74% was obtained at NH3 concentration of 0.016±0.069 mg/L and CO2 as high as 89.89 mg/L while the DO of 4.26 mg/L. The highest growth and survival rate of fry for 17 days post-transportation was treatment E, accounting to 2.95% and 100%, respectively.Keywords: zeolite, active charcoal, closed system transportation, survival rate, gourami fish

ABSTRACTGiant gourami Osphronemus goramy Lac. is one of the most important fresh water fish commodities with increasing production level every year. Water quality management through a proper water exchange both in quantity and quality can be one of the alternatives to support the elevating production. This research was conducted from July to August 2010 at the Aquaculture Production Technology and Management Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine Science, Bogor Agricultural University. The juvenile used was 0.84±0.011 cm in length and 0.017±0.001 cm in weight which reared in nine units of aquaria with a size of 60×29×33 cm3. Silk worm was used as the feed and provided daily at satiation. Water exchange was performed twice a day at a level depending on the treatment, namely 75% (50% at morning and 25% at evening), 100% (50% at morning and evening) and 125% (75% at morning and 50% at evening) of total water volume. Water exchange at 75%, 100%, and 125%/day resulted in survival rates of 94.11±0.63%; 91.89±2.02%; and 93.89±0.75%; specific growth rates of 7.43±0.15%, 8.58±0.24%, and 9.97±0.18%. Growth rate in length of 1.06±0.06 cm, 1.33±0.04 cm, and 1.55±0.01 cm; coefficient of variation in length of 11.31±1.43%, 9.35±1.46%, and 6.90±2.30%; feed efficiency of 12.47±0.30%, 14.32±1.05%, and 19.67±0.54%. The financial benefits resulted of the process were worth of IDR.351,903.00; IDR.402,302.00; and IDR.464,715.00; whereas R/C ratio of 1.71; 1.80; dan 1.90; BEP of 1,845 unit, 1,645 unit, and 1,517 unit; payback period (PP) of 0.97 years, 0.85 years, and 0.74 years; and the cost production as much as IDR.79.90; IDR.82.70; and IDR.82.90/individual, respectively. The treatments were significantly different on several parameters, such as specific growth rate, length of growth rate, feed efficiency at p<0.05. The results of this experiment showed that 125% daily water exchange improved the production performance of giant gourami juvenile cultured at a density of 20 fish/L. For production purpose, rearing giant gourami fish 2 cm in size at a density of 20 fish/L was found as the optimum condition through 125%/day water exchange.Keywords: water exchange, survival rate, growth, gourami fishABSTRAKIkan gurami Osphronemus goramy Lac. merupakan salah satu komoditas penting ikan air tawar dengan produksi yang cenderung meningkat dari tahun ke tahun.
