Abstract

Koi fish commodities have business prospects that can be developed through aquaculture activities in ponds, but in aquaculture, there are often obstacles that are encountered and difficult to control. One obstacle that is difficult to control in the presence of disease attacks caused by parasites. One type of parasite that often attacks koi fish is Myxobolus. Zingiber officinale Rosc. or commonly referred to as red ginger has several properties for the treatment of parasites such as Myxobolus koi, which infects the gills of koi fish. The purpose of this study was to determine the effect of giving red ginger juice (Zingiber officinale Rosc.) To changes in anatomic pathology and the amount of erythrocyte blood of koi fish infected with Myxobolus koi. This study uses a completely randomized design method with six treatments and four replications. The treatments used were different concentrations of red ginger juice that were negative control P1 (healthy fish), positive control P2 (without red ginger juice), P3 (0.1%), P4 (0.2%), P5 (0.3 %) and P6 (0.4%). Pathology scoring data obtained were analyzed using Kruskal Wallis, then followed by an Independent Two-Sample Test, data on the number of erythrocytes obtained were analyzed using ANOVA and then followed by Duncan's Multiple Range Test. The results showed that the administration of red ginger juice gave effect to changes in anatomic pathology and total blood erythrocytes of koi fish infected with Myxobolus. Based on these data, the highest anatomic pathology changes were found in the administration of red ginger concentration of 0.4% with a ranking of 11 and based the on scoring of 2 and the highest average number of erythrocytes found in the treatment of red ginger concentration of 0.4% with an average 14.9 x 105 cells / mm3.

Abstract

The main obstacle to the cultivation of tilapia (Oreochromis niloticus) in the KJA Urban Farming Program in Surabaya is unstable water quality. This is because the reservoirs and bozem used are waters whose water quality depends on the water source so that if the environment experiences a decrease in water quality, the activity of disease agents such as parasites will increase and the health condition of fish will decrease. This condition allows fish to be more susceptible to ectoparasite infestations. This study aims to determine the correlation of water quality with the prevalence of ectoparasites in tilapia in the KJA Urban Farming Program in Surabaya. The method used is a survey method. The results of measurements of water quality parameters indicate that the temperature ranges between 29-30C, pH 7-8.5, brightness 18-30 cm, dissolved oxygen 4.8-5.3 mg / l, nitrite <0.043-2.213 mg / l, nitrate <0.008-7.781 mg / l and ammonia 0.063-0.35 mg / l. The results of the average prevalence of Trichodina ectoparasites were 73.85% and Dactylogyrus ectoparasites were 2.85%. There is a positive correlation between temperature, pH, nitrate, nitrite with the prevalence of Trichodina, and temperature, pH, and nitrate with the prevalence of Dactylogyrus. There is a negative correlation between brightness, dissolved oxygen and ammonia with the prevalence of Trichodina, and brightness, nitrite, dissolved oxygen, and ammonia with the prevalence of Dactylogyrus.

Abstract

The presence of plankton in pond ecosystems fluctuates. Phytoplankton needs nutrients to support their growth. The higher the nutrient content in the waters, the greater the abundance of phytoplankton. The increased abundance of phytoplankton will stimulate the growth of zooplankton. One of the causes of changes in ecosystems in waters is caused by water waste that comes from the rest of the feed and feces and in the form of ammonia or nitrite and nitrate. Water quality is a critical factor in the cultivation process. As a preventative measure, the decrease in water quality in waters is by giving probiotic bacteria. This study aims to obtain information about the effect of giving different commercial probiotics to the diversity and density of seawater plankton in the experimental bath. The method used in this research is descriptive method with a Completely Randomized Design (CRD) as an experimental design. The treatments used are different types of commercial probiotics, with as many as six replications. The main parameters observed were the diversity and density of seawater plankton in the experimental media. Supporting parameters observed were temperature, pH, dissolved oxygen, salinity, ammonia, and C / N and N / P ratio of water. Commercial probiotics are given every 7 days at a dose of 2 mg / l. The results showed that the treatment of different commercial probiotics resulted in differences in diversity, density and plankton dominance. The highest diversity index value (H ') obtained in probiotics A was 6.85 (moderate diversity), and dominance (C) was 0.96, meaning that there was dominant plankton, Chlorella sp. and Oscillatoria sp. whereas the highest plankton density was obtained in probiotics B at week 1 of 5.98x106 ind / ml.

Abstract

Mud crab is one of the fishery commodity which potential to be cultured because it has high economic value. Mud crab has nutrients content such as protein 62,72%, lipid 0,83%, ash 7,5% and water content 9,9%. Trash fish is fresh feed which commonly used as main feed for the growth of mud crab juvenile of 5,3to 13,8%, however Kuniran fish has omega-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) content which is necessary for optimum growth of mud crab.The study method was implemented as the experimental method use Completely Randomized Design (CRD) which consists of five treatments and four replications. The quantity of Crude Fish Oil which is added in trash fish feed on this study are: Treatment A (0%), B (2%), C (4%), D (6%) dan E (8%). The observed parameters are growth of mud crab and feed conversion ratio value. Data analysis use Variant Analysis (ANAVA) and continued with Duncan's Multiple Range Test to determine differences between treatments. The results shows that addition of Crude Fish Oil in trash feed fish for 32 days of rearing gives significantly different effect (P<0,05) toward length and width of mud crab carapace, meanwhile toward feed conversion value of mud crab doesn’t gives significantly different effect (P>0,05). High length and width  growth of carapace were obtained on D and E treatment. The water quality of mud crab during 32 days of rearing is the temperature range of 28-29°C, pH range of 7,5-9,0, salinity range of 15-21ppt, dissolve oxygen range of 4 mg/l and ammonium range of 0,09-0,27 mg/l.

Abstract

Fish farming activities in recent years, many shows water quality conditions do not support fish life are maintained optimally and decreases the carrying capacity, one DO and pH parameters. As a remedial action is carried out either by probiotic bacteria One commonly used in the application of probiotics is Lactobacillus spp. Gram positive bacterium Lactobacillus spp. widely used as probiotics to improve the quality of air Penggunaan Lactobacillus spp. is expected to improve the quality of water that is accelerating the overhaul of organic material in the water and suppress harmful microorganisms that can affect the dynamics of DO, pH and increasing nutrient waters. Barley straw is a powdered extract of hay-producing H2O2 which serves to inhibit the growth of microalgae. The use of straw extract powder has become more common as an alternative method for controlling excessive algae growth by blocking and not get rid of it so that stabilization of the abundance of plankton in the water can be controlled well.To study the role of Lactobacillus spp. and barley straw in the management of organic matter and plankton abundance Giving a research study Lactobacillus spp. and barley straw to the dynamics of DO, pH and Abundance of Plankton.
