Fruktooligosakarida (FOS) merupakan salah satu jenis prebiotik yang berpotensi menjadi feed additive dalam budidaya udang vaname. Penelitian ini bertujuan untuk mengevaluasi suplementasi prebiotik FOS melalui pakan terhadap tingkat ekspresi gen terkait metabolisme dan performa pertumbuhan udang vaname. Pakan uji berupa pakan komersil yang disuplementasi prebiotik FOS (Pre) dengan empat dosis berbeda dan masing-masing terdiri atas tiga ulangan yaitu: Pre-0% (kontrol), Pre-0,5%; Pre-1%, dan Pre-2%. Udang dengan bobot rata-rata 1,58 ± 0,21 g dipelihara dalam bak fiber (volume 1 m3) dengan kepadatan 100 ekor per bak. Pemberian pakan dilakukan selama 30 hari dengan dosis 6% dari bobot biomassa udang. Bobot tubuh diukur setiap 10 hari (n=10) dan tingkat ekspresi gen diukur dari hepatopankreas pada akhir pemeliharaan (n=3) dengan metode quantitative-realtime PCR (qPCR). Hasil penelitian menunjukkan bahwa pemberian prebiotik FOS dapat meningkatkan ekspresi gen terkait metabolisme pada udang vaname. Suplementasi prebiotik FOS memberikan bobot rata-rata, pertumbuhan harian, dan tingkat sintasan yang lebih tinggi dibandingkan dengan perlakuan kontrol (p>0,05). Perlakuan Pre-0,5% menunjukkan rata-rata tingkat ekspresi gen tertinggi, namun performa pertumbuhan, dan sintasan tidak berbeda (p>0,05) dengan perlakuan Pre-2%.Fructooligosaccharides (FOS) are natural feed additives with potential application in feed for Pacific white shrimp. This study aimed to evaluate the effects of prebiotic FOS supplementation on the modulation of metabolism-related gene expression and growth performance of Pacific white shrimp. A trial feed consisted of commercial feed supplemented with different doses of FOS: Pre-0% (control), Pre-0.5%, Pre-1%, and Pre-2%; each with triplicate. Pacific white shrimp with an average body weight of 1.58 ± 0.21 g were reared in fiber tanks (d=1.5 m3) with a density of 100 shrimp/tank for each treatment. The shrimp were given the treatment feed five times per day at 6% of the total body mass for 30 days. Shrimp body weight was measured every ten days (n=10). The gene expression level was measured from the hepatopancreas (n=3) by the quantitative-real time PCR (qPCR) method. The results showed that FOS supplementation increased the metabolism-related gene expression levels. FOS supplementation improved the average body weight, average daily growth, and survival higher than control (p<0.05). Pre-0.5% treatment showed the highest average gene expression despite growth performance and survival were not significantly different (p>0.05) compared to Pre-2% treatment. This study concludes that the application of FOS in the feed improves the growth performance of Pacific white shrimp, notably in gained weight, reduced FCR and improved survival rate.

ABSTRACTLysozymes play an important role in the first line of defense in fish and potentially used as an immunity status biomarker and immune responses evaluation in fish, which often found in two types, i.e. chicken-type and goose-type (c- and g-type, respectively). To recent, the information related to the sequences and the expression analysis of the c- and g-type lysozyme genes in African catfish is still limited. In the present study, we report a partial cloning and mRNA expression analysis of c-type and g-type lysozymes in African catfish Clarias gariepinus. We have successfully cloned and partially identify the c-type, and g-type lysozyme genes of C. gariepinus, which consist of 594 and 560 of coding sequences, respectively. Catalytic and other conserved residues were identified by multiple sequences alignment and they showed high similarity with other teleost fish species. mRNA levels of the genes were analyzed by using qPCR method and their expressions in the spleen, liver, and head kidney were rapidly modulated after Aeromonas hydrophila injection, with different patterns were observed in each organ. These results confirmed that c- and g-type lysozymes played an important role in non-specific immunity against A. hydrophila infection. This study provided valuable information that can be used to understand the African catfish immune systems for better disease and stress management in C. gariepinus culture.Keywords: lysozymes, gene identification, gene expression, bacterial infection, African catfish ABSTRAKLisozim berperan dalam sistem pertahanan dini pada ikan dan sangat potensial digunakan sebagai marka status imunitas dalam evaluasi respons imun. Lisozim umum ditemukan dalam dua tipe pada ikan: tipe-ayam (tipe-c) dan tipe-angsa (tipe-g). Informasi terkait sekuens gen dan ekspresi gen kedua tipe lisozim pada ikan lele dumbo sangat terbatas. Pada penelitian ini, kami melaporkan kloning gen secara parsial, dan analisis ekspresi gen dari kedua tipe lisozim pada ikan lele dumbo C. gariepinus. Sekuens parsial gen lisozim tipe-c dan tipe-g yang berhasil diidentifikasi adalah sepanjang 594 dan 560 pasang basa. Situs katalitik dan residu khas memiliki tingkat kesamaan yang tinggi dengan spesies ikan yang lain. Analisis mRNA dilakukan dengan metode quantitative PCR (qPCR). Ekspresi kedua gen di jaringan ginjal depan, limpa, dan hati dengan cepat terinduksi pasca infeksi bakteri A. hydrophila dengan pola yang berbeda. Hasil ini menunjukkan bahwa lisozim tipe-c dan tipe-g memiliki peran yang sangat penting dalam sistem imun ikan lele dumbo terhadap infeksi A. hydrophila. Penelitian ini menghasilkan informasi penting yang dapat digunakan untuk mempelajari sistem imun ikan lele dumbo dan sebagai acuan dalam penanganan dan manajemen penyakit pada budidaya ikan lele dumbo.Kata kunci: lisozim, identifikasi gen, ekspresi gen, infeksi bakteri, ikan lele dumbo

Aquaculture is a rapidly growing food production sector that plays a vital role in national food security. This study aims to analyze the business model of a Pangasius nursery farm located in Pasir Gaok, Rancabungur District, Bogor Regency, using the Business Model Canvas (BMC) framework. A qualitative descriptive approach was employed, with primary data collected through semi-structured interviews, field observations, and documentation. The results indicate that the Pangasius nursery farm serves local collectors, market traders, and individual buyers, offering consistent fish quality and stable pricing. Feed constitutes the largest cost component, while revenue is mainly derived from the sale of fingerlings. The discussion highlights that business success depends on cost efficiency, effective technical management, and partnerships with research institutions that foster innovation and sustainability in aquaculture enterprises.

Abstract. Authors. 2020. Short Communication: Single nucleotide polymorphism in C-type lysozyme gene and its correlation with Aeromonas hydrophila resistance in African catfish Clarias gariepinus. Biodiversitas 21: 311-317. The chicken-type lysozyme (LYSC) gene has been demonstrated to play important roles in the fish protection system against bacterial infection. In this present study, we aimed to identify the single nucleotide polymorphism (SNP) within the LYSC gene of African catfish Clarias gariepinus and its possible association with Aeromonas hydrophila resistance, a major pathogenic bacterium in African catfish. The gDNA of the African catfish LYSC coding sequence was 1559 bp long, comprising of four exons and three introns. Six SNPs were identified in African catfish LYSC, namely SNP1-6. After the A. hydrophila challenge, we regarded the surviving individuals after the infection as the resistant group and the dead fish as the susceptible group. High-resolution melting (HRM) analysis on SNP2 revealed that the allele frequencies of TT, CC, and TC were of 27.78%, 5.55%, and 66.67% in the resistant group, while the frequencies of TT, CC, and TC were 16.67%, 27.78%, and 55.55% in the susceptible group, respectively. The expression of LYSC and other immune-genes in the resistant group was also higher in the liver, head kidney, and spleen. These results indicated that the LYSC gene might play an essential role in bacterial resistance, and the SNP2 within the LYSC gene may be associated with the resistance to A. hydrophila in African catfish.
