Abstract

The increase in koi fish cultivation can lead to increase risks and caused problems. The main problem is high disease attacks caused by the bacteria Edwardsiella tarda. One of the alternatives to control the disease is immunostimulant treatment with the use of maggot, Hermetia illucens Larvae, known as Black Soldier Fly (BSF). This study aims to report the effect of maggot as a substitute for koi fish feed formulations on the immune system of koi fish infected with E. tarda. This study used a descriptive method, by quantitative approach with the IL-6 and IFN-Ɣ expression through RT-PCR analysis and fish survival rate (%). Identification of E. tarda was carried out by the PCR test method at a molecular weight of 200 bp. The density of bacteria that caused the death of the 50% koi fish population (LD50) for 72 hours was 107 cells/ml. The highest IL-6 expression in the spleen was found in sample C of 28,844 and the lowest in-sample K (+) of 26,096. The highest IL-6 expression in the liver was in sample K (+) of 29,060 and the lowest was in sample D of 25,428. The highest IFN-Ɣ in the spleen was in treatment C, 28,844, and the lowest was in treatment D, 27,219. The highest IFN-Ɣ in liver was sample K (+) of 26,795, and the lowest in-sample C of 25,615. The survival rate of fish in this study reached 30%-100%. The optimal amount of substitution of maggot treatment is 75% (Treatment C) of fish feed.

Abstract

Clarias sp. is one of major genera of freshwater catfish and also common commodity in tropical aquaculture. Excessive light intensity is expected to be responded to by fish as environmental stressors. Fish that experience stress will increase the secretion of catecholamine, cortisol, blood glucose levels and p38 MAPKs in catfish. The different intensity of lights will affect the fish physiological processes. The purpose of this study was to analyze physiological responses (Level of blood glucose, primary stress hormone (Cortisol) and p38 MAPKs) catfish Clarias sp. which were incubated at different lights intensity of catfish. 300 fish were collected from Kepanjen Regency, East Java. Blood and meat sampling are carried out to test the profile of glucose, cortisol, and p38 MAPKs. The experimental research at this stage were carried out by transferred the catfish from Kepanjen to experimental aquarium (50 x 30 x 30 cm) that setted the different lights intensity (0 lux (control), 400 lux, 800 lux and 1200 lux). Each experimental aquarium is filled with 15 catfish and will be kept it for 21 days. Quantificationof the parameter using ELISA method. The study result showed highest peak of primary stress hormone (cortisol) levels are 34±1,50 ng/mL, blood glucose levels are 120±3,4 mg/dL, and p38 MAPK are 97±1,1 %. All of it were achieved in the treatment of 1200 lux on the 2nd week.

Abstract

Indonesia is the largest exporter of eel to consumer countries such as European, America, Taiwan, Japan, South Korea, and the Middle East. Eels are catadromous fish that are in the growth phase in fresh waters and the development phase is in marine waters. Meristic measurement is done by counting the spine (vertebrates). Eel morphometric measurements include TL (Total Length), HL (Head Length), PDL (Pre-Dorsal Length), PAL (Pre-Anal Length) and ADL (Ano-Dorsal Length). The purpose of this study was to analyze the morphological, morphometric, and meristic diversity of intraspecies between populations. Based on the research, the samples identified were morphologically almost the same between the populations, this was seen from the color patterns in the form of plain black or brown and short fins. The morphometric and meristic measurements in the 3D distribution plot still appear to be clustered in one population, while in the dendrogram clade, one species is still congregated in each. The results of the interpretation of the matrix plot of the lowest diversity are the length and number of anodorsal vertebrate segments. This observation can be concluded that the TL and TV of the eel varied, while the PDL, PAL, PDV, PAV, ADV showed the intraspecies character of A. bicolor. This is because the distribution of A. bicolor eels that inhabit the waters of Java Island is widely distributed and random (panmitic).

Abstract

Aquaculture has a land potential of 17.92 million ha consisting of 2.83 million ha of freshwater aquaculture potential, 2.96 million ha of brackish water aquaculture and 12.12 million ha of marine aquaculture. One of the freshwater species that has the potential to be cultivated is catfish (C. gariepinus). But now, as a result of the decline in the quality of the freshwater environment, catfish are prone to contamination by plastic waste. If microplastic particles have accumulated in large numbers in the fish's body, it can clog the fish's digestive tract and affect the growth of catfish which will affect the results of aquaculture production. The purpose of this study was to determine the survival rate or survival rate of catfish exposed to microplastics. The research design used in this study was a Completely Randomized Design (CRD) with 1 control variable, namely no mixing of microplastics in commercial feeds and 3 different doses of microplastics, namely A (5%), B (10%), C (15%) mixed with commercial feed, where each treatment was repeated 3 times. The results of the one way ANOVA analysis showed that the treatment of exposure to microplastics with different doses did not have a significant effect (P<0.05) on the survival rate and length growth of catfish. The survival rate ranges from 65- 100%. Survival values that were not significantly different could indicate that there was competition for space and dominance of larger fish in the aquarium which affected fish growth, feed utilization and fish survival. Meanwhile, the length growth value ranged from 21-28cm. The length growth value which was not significantly different could indicate that the dose of microplastic used in the study did not result in muscle and bone cell division which was the cause of the increase in body length of fish.

Abstract

Aquaculture activities cannot be separated from obstacles that can lead to failure of aquaculture, including the presence of microplastics. Microplastic polystyrene (styrofoam) is a type of plastic that is commonly found in aquatic organisms (35%). Microplastics in fish can cause hormonal disturbances and high vacuolation in gonads which can cause apoptosis in gonadal cells. This study aimed to determine the effect of microplastics exposure on catfish (Clarias gariepinus) feed on the gonadal histology of male catfish. The research design used an experimental method with a Completely Randomized Design (CRD) which was divided into four treatments and three replications, namely 3% of the feed rate with treatments A (5% microplastics), B (10% microplastics), C (15% microplastics), and K (0% microplastics). Microplastic exposure treatment was given to fish by mixing it with commercial feed for 30 days. The results showed that microplastic exposure had a significant effect on the 15th and 30th days of the study on the Gonad Maturity Level (GML) and Gonado Somatic Index (GSI) of male catfish (C. gariepinus) in treatments A, B and C compared to controls (K). Treatment C (Microplastics 15%) had the lowest GML and GSI values, while treatment K (Microplastics 0%) had the highest GML and GSI values. Treatments A, B, and C experienced changes and delays in the development of gonadal cell structure, while control (K) developed well. This is presumably because the nutritional needs of control fish (K) were more fulfilled than treatments A, B and C exposed to microplastics.

Abstract

Barriers to cultivation activities are disease attacks, one of which is caused by infection with the bacterium Edwardsiella tarda. Treatment efforts can be made using natural ingredients such as jackfruit (A. heterophyllus) leaves. This study aims to determine the content of antibacterial compounds in the jackfruit (A. heterophyllus) leaves crude extract and their effect on Edwardsiella tarda bacteria in vitro. The inhibition test used disc test with five different concentrations of jackfruit (A. heterophyllus) leaves crude extract with three replications: 75 mg/L, 150 mg/L, 225 mg/L, 300 mg/L and 375 mg/L with a comparison using two types of controls (positive with 5 mg/L chloramphenicol antibiotics and negative with no treatment) using Tryptone Soy Agar (TSA) media and incubated for 2x24 hours. The results of phytochemical screening proved that the jackfruit (A. heterophyllus) leaves crude extract contains flavonoids, alkaloids, tannins and saponins. Treatment E with a dose of 375 mg/L gave the highest inhibition of 7.80 mm and treatment A with a dose of 75 mg/L gave the lowest inhibition of 4.38 mm.  The relationship between the treatment given to the test parameter in the form of the resulting inhibitory power obtained the equation y = 0.0111x + 3.6297 with an R2 value of 0.974 which means 97% of the treatment given in the form of crude extract of jackfruit (A. heterophyllus) leaves affects inhibition of bacteria E. tarda.
