Abstract

Catfish Clarias sp. is one of the leading commodities in demand and has economic value. Low survival due to cannibalism and disease is a serious problem. To overcome these problems is application of bioflocs and probiotics Bacillus NP5. This study aimed to analyze the appropriate dose of Bacillus NP5 probiotic addition to the biofloc system to improve the health status, growth performance, water quality, and resistance to A. hydrophila. The catfish fry (Clarias sp.) with an average weight of 1.79±0.05 g was used in the experiment for 40 days, reared in tanks with the dimension of 60×30×35 cm3. The experiment applied a completely randomized design (CRD) of five treatments with three replicates, namely KN (negative control), KP (positive control), BFT (biofloc application without probiotic bacteria), BFT4 (biofloc application with Bacillus NP5 104 CFU mL-1), BFT6 (biofloc application with Bacillus NP5 106 CFU mL-1). Treatments tested were challenged with A. hydrophila density 104 CFU mL-1 by immersion, except the negative control. After 40 days of rearing, biofloc and Bacillus NP5 treatments had a significant effect (P < 0.05) on growth performance, immune response, water quality, total bacteria in water and the gut compared to the control treatment (P < 0.05). In addition, total A. hydrophila in liver, kidney and water were lower (P < 0.05) in BFT4 and BFT6 treatments than the control. The conclusion of this study is that the bioflocs supplemented with Bacillus NP5 improved the growth performance, immune response and resistance of catfish to A. hydrophila infection.

Abstract

Udang vaname (Litopenaeus vannamei) merupakan salah satu komoditas perikanan budidaya yang dapat memenuhi kebutuhan protein hewani bagi masyarakat. Sistem pemeliharaan udang vaname dapat dilakukan secara tradisional dan intensif. Tantangan terbesar kegiatan budidaya udang saat ini adalah penyakit yang dapat menimbulkan kerugian bagi pembudidaya. Serangan penyakit yang disebabkan oleh parasit terutama jenis protozoa yang sering menyerang udang vaname adalah Zoothamnium sp., Vorticella sp. dan Epistylis sp. yang menyebabkan penyakit Enterocytozoon hepatopenaei atau EHP. Penelitian ini bertujuan untuk mengetahui perbandingan jenis parasit, prevalensi, intensitas serangan parasit dan kualitas air pada udang vanname di tambak intensif dan tradisional. Metode penelitian yang digunakan adalah metode deskriptif dengan metode pengambilan sampel secara purposive random sampling. Sampel yang diambil pada saat berumur atau DOC 35 – 90 hari dengan berat rata-rata per ekor atau ABW 1 sampai 10.0gr/ekor. Pemeriksaan ektoparasit dilakukan pada kaki jalan, kaki renang, insang, dan lendir. Parameter yang diamati meliputi prevalensi dan intensitas penyakit, kualitas air seperti alkalinitas, total organic matter (TOM), Nitrit (NO₂) dan amoniak (NH₄). Hasil pengamatan parasit pada udang vaname yang dipelihara di tambak intensif dan tradisional terdapat tiga spesies teridentifikasi yang menginfeksi yaitu Epistylis sp., Vorticella sp., dan Zoothamnium sp. dengan prevalensi pada tambak intensif lebih tinggi dibandingkan dengan prevalensi pada tambak tradisional yakni sebesar 95,56% dan 56,6%, begitupula dengan hasil perhitungan intensitas menunjukkan persentasi intensitas pada tambak intensif lebih tinggi dibandingkan tambak tradisional dengan nilai masing-masing sebesar 4,3 dan 2,46 ind/ekor. Kualitas air seperti alkalinitas, NO₂, NH₄, dan TOM pada tambak intensif memiliki nilai yang lebih tinggi dibandingkan dengan tambak tradisional.

Abstract

Krisis pangan global dan tingginya kebutuhan protein hewani menuntut adanya sumber protein alternatif yang berkelanjutan dalam akuakultur. Ketergantungan pada tepung ikan sebagai bahan pakan utama menghadapi kendala berupa keterbatasan pasokan dan fluktuasi harga, sehingga diperlukan eksplorasi bahan nabati dengan potensi tinggi, antara lain jarak pagar (Jatropha curcas). Artikel ini bertujuan untuk mengkaji potensi jarak pagar sebagai sumber protein alternatif dalam pakan akuakultur.  Metode penelitian yang digunakan dalam kajian ini adalah metode kualitatif dengan teknik pengumpulan data melalui studi literatur atau kajian pustaka. Data diperoleh dengan  mempelajari teori, konsep, dan hasil penelitian terdahulu yang relevan dengan topik. Sumber kajian berasal artikel jurnal bereputasi nasional, internasional dan prosiding yang diterbitkan dari tahun 2010-2025. Proses pengumpulan literatur dilakukan melalui berbagai basis data seperti Scopus, Web of Science, PubMed, MDPI, Springer Link dan Google Scholar dengan menggunakan kata kunci yang sesuai.Hasil kajian menunjukkan bahwa jarak pagar mengandung protein tinggi 56–64% dengan profil asam amino lengkap serta senyawa bioaktif (flavonoid 0,09–2,92%, saponin 0,092–3,5%, tanin 0.0049–0,395%, fenolik 0,48-38%, alkaloid 0,070-0,50% terpenoid 0,022%) yang berfungsi sebagai imunostimulan. Proses detoksifikasi mampu menurunkan kandungan antinutrisi hingga 85%. Aplikasinya dalam pakan mampu menggantikan tepung ikan dan kedelai sebesar 10–40%, meningkatkan pertumbuhan, efisiensi pakan, respons imun, dan kelangsungan hidup organisme budidaya hingga 88,3%. Kajian ini menyimpulkan jarak pagar memiliki potensi sebagai sumber protein alternatif dalam pakan akuakultur karena kandungan nutrisinya yang tinggi dan keberadaan senyawa bioaktif yang bermanfaat melalui metode pengolahan yang tepat. Namun, pemanfaatannya masih terbatas oleh kandungan senyawa toksik yang memerlukan proses detoksifikasi efektif dan aman. Tantangan riset ke depan mencakup optimalisasi teknologi detoksifikasi dan analisis kelayakan aplikasinya dalam skala industri.The global food crisis and the increasing demand for animal protein necessitate sustainable alternative protein sources in aquaculture. Dependence on fishmeal as the primary feed ingredient faces challenges due to limited supply and fluctuating prices, making it essential to explore high-potential plant-based materials such as Jatropha curcas. This article aims to review the potential of Jatropha curcas as a protein source alternative in aquaculture feed. The research employed a qualitative method through a literature review, analyzing theories, concepts, and previous studies relevant to the topic. The data sources were peer-reviewed national and international articles and conference proceedings published between 2010 and 2025. Literature was collected from various databases, including Scopus, Web of Science, PubMed, MDPI, Springer Link, and Google Scholar, using predetermined keywords. The findings indicate that Jatropha curcas contains high protein (56–64%) with a complete amino acid profile and bioactive compounds (flavonoids 0.09–2.92%, saponins 0.092–3.5%, tannins 0.0049–0.395%, phenolics 0.48–38%, alkaloids 0.070–0.50%, terpenoids 0.022%) that function as immunostimulants. Detoxification processes can reduce antinutritional factors by up to 85%. Its application in aquafeed can substitute 10–40% of fishmeal and soybean meal, improving growth, feed efficiency, immune response, and survival rate of cultured organisms up to 88.3%. This review concludes that Jatropha curcas has strong potential as an alternative protein source in aquaculture feed due to its high nutritional content and beneficial bioactive compounds when processed appropriately. However, its utilization remains constrained by toxic compounds that require effective and safe detoxification. Future research challenges include optimizing detoxification technologies and evaluating the plant feasibility for industrial-scale applications.

Abstract

Cultivation of the seaweed Gracilaria verrucosa is necessary as a preventive measure against overexploitation. One applicable method is tissue culture, which requires special attention to nutrient needs to support accelerated growth. These nutrients can be provided through fertilization. One commonly used chemical fertilizer in seaweed tissue culture is Provasoli’s Enriched Seawater (PES). This study aims to determine the optimal PES fertilizer dosage for the production of G. verrucosa seedlings through tissue culture using a vegetative propagation method. This study used a completely randomized design with analysis of variance (ANOVA) consisting of four treatments of different PES fertilizer doses with three replicates for each treatment. The results showed that fertilizer dose variation did not significantly affect the absolute growth of explant weight, but tended to increase the number of growth points. Growth points began to increase in the second week for all treatments, and by the fourth week, the number of growth points at a 1.5% dosage showed a significant difference compared to other doses. The application of PES fertilizer in G. verrucosa seedling production through tissue culture with vegetative propagation indicates that different fertilizer doses do not affect explant growth but significantly influence the increase in growth points by the fourth week
