Abstract

Natural betta fish is one of the Betta fish that comes from nature and still has high genetic diversity because it has not been crossed with cultivated Betta fish. Many environmental changes affect the reproduction of natural betta fish in their natural habitat, so it is necessary to carry out studies related to the reproductive biology of natural betta fish (Betta picta). This research aims to determine various reproductive biology and the influence of water quality on the gonad maturity level of natural betta fish (B. picta). The research was conducted from October to November 2023 in the Gending River, Mertoyudan District, Magelang Regency, and the Integrated Laboratory of Tidar University. Fish samples were caught using a seser and placed in plastic containers for observation in the laboratory. The gonad maturity level, or GMI, was observed morphologically and analyzed descriptively. The results of this research were that the TKG consisted of TKG I-TKG V, the IKG value was 4.7%, the IG value was 48.2, the HSI value was 0.7%, the sex ratio was 1:1, the relationship between length and weight was allometric negative, and plankton abundance was 166.6ind/l. There was an increase in the second week of observation up to the sixth week.

Abstract

Freshwater lobster is one of the lobster commodities that is not widely known by society today. Freshwater lobsters have a high selling value on the market, so information on growth hormones is needed to increase the growth of freshwater lobsters, so that they can meet market demand. Thyroxine hormone is a hormone produced by the thyroid gland which functions to form, store and release substances related to regulating metabolic rate. Therefore, this study aims to see how different soaking times for the thyroxine hormone affect the growth rate of freshwater lobsters and to determine the optimal time for soaking freshwater lobsters using the thyroxine hormone. The research method used in the research was a Completely Randomized Design (CRD) method with 4 treatments and 3 three replications. The treatments carried out were: PHT0 (control), PHT1 (soaking for 12 hours/0.1 mg/L), PHT2 (soaking for 24 hours/0.1 mg/L), PHT3 (soaking for 36 hours/0.1 mg/L). Parameters observed: Absolute Weight Growth, Absolute Length Growth, Daily Growth Rate, Survival Rate (SR), and Water Quality Observations. The results of the research showed that the best soaking time for the thyroxine hormone on the growth of freshwater lobsters (Cherax quadricarinatus) was in PHT2 (24 hours), and the lowest was in PHT0 (control) treatment.

Abstract

This study aimed to determine the supplementation of yellow pumpkin peel powder on the coloration of lemon fish. The powder lemon fish with an average length of 3 cm and a weight of 0.83 g as many as 240 fish. This study used a completely randomized design (CRD) consisting of four treatments and four replicates, namely P1 (0 g/100 g feed), P2 (5 g/100 g feed), P3 (10 g/100 g feed), and P4 (15 g/100 g feed). The aquariums used were 50x30x30 cm in size, with 16 aquariums and 15 fish per aquarium. The fish were reared for 30 days and fed based on fish biomass. The parameters observed were growth performance (absolute weight, absolute length, and survival), water quality, feed nutrient levels, and increased color intensity. Data on growth performance and increased color intensity were analyzed using a one-way analysis of variance (one-way ANOVA) to determine the real difference between each treatment and followed by the Duncan multiple distance test (DMRT) with a 95% confidence interval (p<0.05). Water quality data and feed nutrient levels were analyzed descriptively. The results of the study showed that dietary supplementation with yellow pumpkin peel powder did not affect the growth performance of lemon fish, but it did affect the coloration of lemon fish. The best treatment for increasing the color of lemon fish was P4, with a color increase value of 31.5%.

Abstract

In fish farming activities, problems often arise that must be faced by farmers, the main factor causing the failure of fish farming efforts is the emergence of disease attacks. The type of disease that often attacks carp (Cyprinus carpio) is the bacteria Aeromonas hydrophila. Efforts made by farmers using artificial drugs or antibiotics. The use of antibiotics does not always have a positive effect; there are also negative effects. Therefore, natural, environmentally friendly handling is needed, and water lily leaf extract plants (Crinum asiaticum L.) are able to treat A. hyrophila infections in farmed fish. This study aims to determine the soaking of water lily leaf extract on the survival and optimal concentration that can reduce infection in carp juvenile (Cyprinus carpio). The research method used is an experiment with a Completely Randomized Design (CRD) consisting of 3 treatments and 3 replications. Treatment P1 (20 ml of water lily leaf extract), treatment P2 (40 ml of water lily leaf extract), and P3 (60 ml of water lily leaf extract). Data were analyzed using Analysis of Variance (ANOVA). If the results were significantly different, they were followed up with the Least Significant Difference (LSD) test. The results showed that the provision of water lily leaf extract (Crinum asiaticum L.) soaking had a very significant effect on the survival of carp (Cyprinus carpio) juvenile. The optimal concentration that can reduce A. hyrophila bacterial infection is in treatment P1 (20 ml) with the highest survival rate of 90%. Water quality during the study obtained a temperature value between 23-27.3 oC, pH between 6.9-8.45, and DO levels between 4.1-8.3 mg/l.

Abstract

Pomfret (Colossoma macropomum) is a freshwater fish that is one of the leading commodities in Indonesia, and has good prospects for development because it has a delicious and savory taste. The obstacle that is often faced today in pomfret cultivation is the high Feeding Rate value in pomfret fish is not comparable to the growth produced by efforts made to increase growth and survival in pomfret fish, namely by adding VCO and fish oil to commercial feed. The research design used in this study was an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications where P1: 7% Fish oil / kg feed, P2: 5% Fish oil + 2% VCO / kg feed, P3: 3% Fish Oil + 4% VCO / kg feed, and P4: 7% VCO / kg feed. The results obtained on absolute weight growth showed the best treatment, namely in P3, which was 10.46 g, while the best survival rate was in P1, which was 96.67%. In P1, where fish oil is 7% with a survival value of 96.67%, this is because fish oil contains omega-3 fatty acids such as DHA and EPA which are important for increasing the immunity and physiological function of pomfret fish.

Abstract

Reservoirs are one of the waters used for fishing activities. One of them is the Gajah Mungkur Reservoir which is used for cultivating tilapia using the KJA system. Activities around the reservoir can affect the quality of the water in it. The aim of this research is to determine the condition of reservoir water quality and to determine the suitability of reservoir waters for tilapia cultivation activities in the KJA system. The method used in this research is the matching and scoring method, which is then used to obtain the water suitability value. The ArcGIS application is also used to map and calculate the area that can be used for cultivation. The parameters measured are temperature, brightness, depth, current speed, basic substrate, pH, DO, CO₂,nitrate, ammonia, and phosphate. The suitability of the waters of the Gajah Mungkur Reservoir at 6 station points is divided into 3 classifications, namely, stations 1 and 2 are in the S3 category (marginally suitable), stations 3, 4 and 6 are in the S2 category (quite suitable) and station 5 is in the S1 category (very suitable). The scores obtained by each station are as follows: station 1 with a score of 34 (70.83%), station 2 with a score of 33 (68.75%), station 3 with a score of 37 (77.08%), station 4 with a score of 40 (83.33%), station 5 with a score of 43 (89.58%), and station 6 with a score of 39 (81.25%). The overall results show that the Gajah Mungkur Reservoir has a suitability value in the S2 category or is moderately suitable.

Abstract

Water quality is a crucial factor in the cultivation of Sangkuriang catfish (Clarias gariepinus). One of the main issues in catfish farming is the increase in ammonia levels in the water, which can negatively impact fish health and the environment. This study aims to analyze the effectiveness of the phytoremediation method using Eichhornia crassipes (water hyacinth), Pistia stratiotes (water lettuce), and Azolla microphylla in reducing ammonia levels from catfish farming wastewater. The research employed an experimental method with a completely randomized design (CRD), consisting of three treatments using each plant type and a control group without treatment. The results showed that the phytoremediation method using water hyacinth was the most effective in reducing ammonia levels, achieving an efficiency of 99.35%. Water lettuce and Azolla microphylla also demonstrated effectiveness in absorbing ammonia, with efficiencies of 98.2% and 96.4%, respectively. Additionally, water quality parameters such as temperature, pH, dissolved oxygen (DO), phosphate, and nitrate were within the optimal range for fish farming. Based on these findings, the phytoremediation method using aquatic plants can be an environmentally friendly solution for managing catfish farming wastewater. Further research is needed to optimize environmental conditions and the number of plants used in the phytoremediation process.
