Abstract

Interest in the cultivation of koi carp commodities has increased during the Covid-19 pandemic. Breeders come from various communities. This study aims to determine whether topographic differences have an effect or not on the growth of koi carp. The research was conducted from February to March 2022 for 45 days. The location of the research was carried out in three different places, Kaliangkrik, Tempuran, and Kebumen. The research method used was a Completely Randomized Design (CRD) with 3 treatments and 3 repetitions. The first treatment is an altitude of 1,030 meters above sea level (Kaliangkrik), the second is 323 meters above sea level (Tempuran), and the third is 26 meters above sea level (Kebumen). The data were analyzed using the Analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) further tests. The results showed that topographic differences affect the growth of koi fish both in weight and length growth of koi fish. The altitude that produces the best growth in this study is at an altitude of 26 meters above sea level or located in Kebumen. This is supported by the data showing the highest weight (average 4,1 g), the longest (average 2.5 cm), the lowest FCR (average 2,16), and the highest Survival Rate (SR) high (80%).

Abstract

Raising striped catfish (Pangasianodon hypophthalmus) in dark conditions with low salinity (5 ppt) can support growth but may also cause stress and affect blood health. Adding Cosmos caudatus leaves, which contain natural bioactive compounds, in fish feed could offer a natural way to help boost the immune system. This study aimed to understand the hematological response of fish toward the C.caudatus enriched feed provision. The fish were reared for 60 days in 5 ppt salinity water and under a controlled photoperiod. There were four treatments: control (no C.caudatus) T1, T2 and T3 (10 g, 20 g, and 30 g of C.caudatus leave powder in 1 kg of feed). Parameters observed were red and white blood cell number, hemoglobin, hematocrit and glucose concentration, phagocytic activity, leukocrit, and types of white blood cells. Results showed that the T1 group significantly improved the ability of red blood cells, hemoglobin, hematocrit, and phagocytosis. Survival rates were high and showed no significant differences between treatments, suggesting that C.caudatus up to 30 g/kg is safe. Based on these findings, a dose of 10 g/kg can be recommended as an effective natural feed additive to help improve the health and immune system of P.hypopthalmus cultured in controlled rearing conditions

Abstract

The richest eco-tourism potential and real ecosystem of Yashil Gol were studied using remote sensing methods in aerospace sources. Based on these materials, the eco-geographical factors of the lake were revealed using OpenStreetMap and Google Earth. The lake territory comprises 2,551 m² (0.26 ha), and the total perimeter of the lake circle is 202.4 m. The lake’s absolute height is about 909 m above sea level, and the relative height is 1.37 km. The lake shape resembles an oval leaf from space. Consequently, the map length is 76.60 m, but the ground length is approximately 76.96 m, with a heading of 193.43° on the Google Earth map. The lake’s map width is 63.37 m, but the ground width reaches 63.39 m, with a heading of 90.59 ° on the Google Earth map. Yashil Gol is located at 40°45'35"N latitude and 48°32'19"E longitude. The eco-tourism reserves of Yashil Gol haven't been studied by researchers today. Correspondingly, the climate conditions of the lake territory were investigated, and the data are presented in the paper. According to Landsat and other aerospace materials, as well as visits to the lake throughout the four seasons, monitoring deals with climate, forest, and visitor impacts. The woodland cover square around the lake was defined as about 0.88 ha within a 678 m perimeter. There is only one small café on the lakeshore. None of the cottages, hotels, or hostels are located here. Orthofauna members are observed in Autumn as wild birds migrate to warmer areas. The birds are mainly included in the «Green Book» and «Red Book» of the Republic. To investigate the entire ecosystem of Yashil Gol, researchers from various scientific fields must study it.

Abstract

Red tilapia is a fish with a relatively wide tolerance to salinity (euryhaline) changes, making it possible to cultivate red tilapia in brackish waters. Additionally, intensive farming environments can support increased stocking density. The application of biofloc technology can help address this issue. Biofloc technology is an alternative approach to addressing water quality issues in water bodies, adapted from conventional domestic wastewater treatment techniques, and can also serve as a source of natural food. This research aimed to determine the best stocking density of red tilapia reared in brackish water using biofloc technology. The method used in this research is the experimental method of Completely Randomized Design (CRD) with one factor, five levels of treatment, and three replicates. The treatments applied were 20 fish/80 L (P1), 30 fish/80 L (P2), 40 fish/80 L (P3), 50 fish/80 L (P4) and 60 fish/80 L (P5). The red tilapia used as test fish were 3-5 cm in size and adapted to 17 ppt salinity. Feed with commercial pellets 3 times a day in sufficient amounts. This research was conducted for 50 days. The results showed the best stocking density was obtained in P4 (50 fish/80 L) which produced absolute weight of 8,87 ± 0,12 g, absolute length of 3,57 ± 0,07 cm, specific growth rate of 3,55 ± 0,12%, feed conversion ratio of 0,83 ± 0,06 kg, feed efficiency of 120,32 ± 7,81%, survival rate of 86 ± 4% and blood glucose level of 71 ± 5,13 mg/dL.

Abstract

Polymesoda expanse belongs to the class of Bivalves found in mangrove forests; their habitat is between mangrove roots on muddy substrates, sandy mud and mangrove litter. This study aims to determine the abundance of P. expansa in Anak Setatah Village, Kepulauan Meranti Regency, examine the size-frequency distribution, and investigate the distribution pattern in the area. The study was conducted in October 2024 by using a survey method. The sites were located in the coastal waters of Anak Setatah Village. Station I is near residential areas, Station II is near fishing ports, and Station III is near agricultural areas. A one-way ANOVA was used to analyse differences in abundance between stations and zones. The results revealed significant differences in abundance, with Station II (near fishing ports) exhibiting the highest abundance and Station I (near residential areas) showing the lowest. The middle zone had the highest abundance among the zones. Furthermore, based on the results of the ANOVA test (p< 0.05), there is a significant difference in abundance between stations. The LSD test revealed a substantial difference in abundance between stations I and II, and stations I and III. However, no significant difference was found from the ANOVA test, with a p-value of 0.125 > 0.05, indicating that there was no significant difference in abundance between zones. The size frequency of P. expansa ranged from 17.6-64.8 mm, and the distribution pattern was clustered

Abstract

This study aims to determine the immunity response of  Carassius auratus infected with Aeromonas hydrophila bacteria and post-treatment with propolis solution by measuring total leukocytes and phagocytosis index. The method used is experimental by applying a completely randomized design (CRD) with five treatments and three replications. The treatments were Kn (not infected with A. hydrophila and not treated with propolis), Kp (infected with A. hydrophila but not treated with propolis), while fish infected with A. hydrophila were treated with propolis doses P1 (700 ppm), P2 (800 ppm), and P3 (900 ppm). Treatment was done by injecting 0.1 ml of propolis into fish infected with A. hydrophila intramuscularly. The test material was 150 fish of 8-10 cm in size. The results showed that propolis significantly gave an immune response to the C. auratus infected with A. hydrophila (p<0.05). The 800 ppm propolis dose was the most effective, as indicated by a total leukocyte count of 3.70×104 cells/mm3, a phagocytosis index value of 28.33%, and a survival rate of 83.33%. This study highlights that propolis has potential as a natural immunostimulatory agent in enhancing non-specific defense mechanisms in C. auratus infected with pathogenic bacteria
