The obstacle faced by snakehead fish farmers is the provision of feed that has quality and a high protein content for the growth period of fish. Natural feed can be an alternative. The purpose of this study was to determine the effect of the natural feeding of gold snails, earthworms, and Hongkong caterpillar types on the growth of snakehead fish. The research was conducted from January to February 2022, in Adipasir Village RT. 07 RW. 02 Rakit District, Banjarnegara Regency, Central Java. The method used in this study was experimentally arranged using a completely randomized design (CRD). This study consisted of 4 treatments with 4 replications and each treatment consisted of 5 snakehead fish so the number of containers used was 16 pieces and 80 snakehead fish. The analysis used was a one-way Analysis of Variance (ANOVA) with an error level of α = 0.05. The treatment consisted of T1 (control with Pellet), T2 (gold snail), T3 (earthworms), and T4 (Hongkong Caterpillars). The results showed that natural feeding influences the growth of snakehead fish. The best treatment is natural food in the form of a Hongkong caterpillar with an absolute weight of 4.7475 g, an absolute length of 3.63 cm, FCR of 1.07.

Peningkatan kualitas warna tubuh ikan hias seperti ikan cupang (Betta sp) merupakan salah satu faktor penting dalam menunjang nilai jual dan daya tariknya. Salah satu upaya yang dapat dilakukan adalah melalui pemberian pakan alami yang diperkaya nutrisi. Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi tepung wortel dan tepung bit pada cacing sutra (Tubifex sp.) terhadap kandungan nutrisi cacing serta dampaknya terhadap warna tubuh dan pertumbuhan ikan cupang. Penelitian dilaksanakan di Kramat Selatan, Magelang Utara, menggunakan metode Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan dua ulangan. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT). Variabel utama yang diamati meliputi kandungan nutrisi cacing sutra, intensitas warna tubuh ikan cupang, serta pertumbuhan bobot dan panjang ikan. Kualitas air dipantau sebagai variabel pendukung. Hasil penelitian menunjukkan bahwa suplementasi tepung wortel dan tepung bit meningkatkan kandungan nutrisi cacing sutra, terutama pada kadar abu, lemak, dan serat. Pemberian cacing sutra yang telah diperkaya tersebut berkontribusi terhadap peningkatan warna tubuh ikan cupang secara signifikan, dengan perlakuan P2 menunjukkan rata-rata intensitas warna sebesar 22,78% dan perbedaan nyata berdasarkan hasil analisis ANOVA dan DMRT (p<0,05). Kesimpulannya, suplementasi tepung wortel dan bit pada pakan cacing sutra efektif dalam meningkatkan kualitas nutrisi cacing dan memperbaiki kualitas warna tubuh ikan cupang

Ikan beong memiliki potensi pasar yang menjanjikan sebagai produk perikanan, namun produksi ikan ini menghadapi beberapa tantangan, termasuk pertumbuhan yang lambat, sifat kanibalisme yang tinggi, sensitivitas tinggi terhadap kualitas air, dan sangat rentan terhadap penyakit. Pemberian bakteri probiotik yang dikembangkan dari saluran pencernaan ikan dapat mencegah resistensi bakteri. Sebelumnya, bakteri asam laktat (BAL) dengan kode UBB7 dari saluran pencernaan ikan beong telah berhasil diisolasi. Namun, konfirmasi akurat tentang sifat antibakteri dan identifikasi spesies isolat bakteri ini belum pernah ditemukan. Penelitian ini bertujuan untuk mengkonfirmasi sifat antibakteri dan mengidentifikasi spesies isolat UBB7 berdasarkan analisis gen 16S rRNA. Metode penelitian ini adalah pemurnian dan pewarnaan Gram isolat UBB7, ekstraksi, amplifikasi, elektroforesis dan sekuensing. Hasil pewarnaan Gram menunjukkan isolat UBB7 adalah bakteri Gram-positif berbentuk kokus dengan sifat antibakteri yang lebih kuat terhadap Streptococcus agalactiae dibandingkan dengan Aeromonas hydrophila (zona hambat 16,2 mm vs 14,1 mm). Nilai kemurnian DNA isolat UBB7 menunjukkan 1,98 (panjang gelombang/λ = 260/280) dan 3,72 (λ = 260/230) dan memiliki panjang 1412 pasang basa (bp). Hasil Basic Local Alignment Search Tool BLAST menunjukkan bahwa isolat UBB7 diidentifikasi sebagai Lactococcus cremoris strain 4136. Bakteri ini dapat diaplikasikan lebih lanjut sebagai probiotik, jika diteliti secara luas di masa depan untuk industri akuakultur

Optimizing nutrient utilization and minimizing feed costs are essential for supporting fish growth, with winged bean presenting a viable solution. This study aimed to determine the optimal dosage of dietary winged bean extract supplementation to enhance the growth performance of catfish. Catfish (mean weight 7.44 ± 0.16 g) were stocked at a density of 1 fish/L in 20 L containers. A completely randomized design was utilized, comprising four treatment groups based on the dosage of winged bean seed extract: 0 ml/kg feed (P1), 10 ml/kg feed (P2), 30 ml/kg feed (P3), and 50 ml/kg feed (P4), with each treatment replicated four times. Growth performance parameters included absolute length (Pm), absolute weight (Wm), feed intake (FI), feed conversion ratio (FCR), specific growth rate (SGR), and survival rate (SR). Data were analyzed using a one-way ANOVA, followed by Duncan's Multiple Range Test at a 95% confidence level (p<0.05). Catfish fed P4 exhibited the best growth performance, with Pm of 4.32 ± 0.51 cm, Wm of 15.75 ± 2.75 g, SGR of 52.49 ± 9.18%/day, and FCR of 1.21 ± 0.09, though insignificantly different from P3. This study concluded that 50 ml/kg feed of winged bean seed extract optimally enhances catfish growth performance.

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.

Environmental stressors are external factors that can negatively impact aquatic life, especially fish, as they are considered the main indicators of ecosystem health due to their sensitivity to environmental changes. The purpose of this study was to determine the level of stress in fish (especially catfish and tilapia) based on the blood glucose concentration of fish cultivated in Magelang Regency, Central Java. The data analysis used was spatial analysis to describe the spatial conditions of topographic parameters, air temperature, pond water temperature, and blood glucose concentration of fish (tilapia and catfish). Crosscorrelation multiple variable analysis was used to determine the correlation coefficient value between each parameter. The Crosscorrelation Multiple Variable Analysis method with the Pearson Product-Moment Correlation model. The results of the analysis of blood glucose concentration of catfish were 59.59 mg/dL and tilapia 87.80 mg/dL, so in general it can be concluded that the influence or correlation between water parameters on the level of stress of fish in the Magelang Regency area is tiny, which indicates that the condition of catfish and tilapia is not experiencing stress, where the average blood glucose is still at a normal level. The correlation coefficient value between water temperature and blood glucose of tilapia is -0.06, and that of catfish is -0.41, which means that the relationship between pond water temperature and stress levels of tilapia and catfish is fragile.
