Abstract

Pertumbuhan sektor akuakultur yang pesat telah menjadi respons terhadap meningkatnya permintaan protein hewani global, namun ekspansi yang tidak terkendali menimbulkan dampak negatif terhadap lingkungan, sosial, dan ekonomi. Konsep Blue Economy menawarkan kerangka pembangunan alternatif yang mengintegrasikan pertumbuhan ekonomi dengan pelestarian ekosistem kelautan. Review artikel ini bertujuan mensintesis literatur terkini mengenai penerapan pendekatan Blue Economy dalam manajemen budidaya ikan berkelanjutan. Kajian ini mengeksplorasi berbagai sistem produksi berkelanjutan seperti Integrated Multitrophic Aquaculture (IMTA), Recirculating Aquaculture Systems (RAS), dan aquaponik yang terbukti mampu mengurangi limbah, meningkatkan efisiensi sumber daya, dan mendiversifikasi produk. Implementasi Blue Economy juga mencakup dimensi sosial-ekonomi melalui pemberdayaan masyarakat lokal, pengembangan kapasitas, peningkatan akses pasar dan pembiayaan, serta penciptaan lapangan kerja. Hasil kajian menunjukkan bahwa pendekatan ini mampu mengurangi beban nitrogen hingga 40-50% dan fosfor hingga 30-40% melalui sistem IMTA, serta menghemat konsumsi air hingga 99% melalui RAS. Meskipun menjanjikan, implementasi masih menghadapi hambatan berupa keterbatasan investasi, kompleksitas regulasi, dan kurangnya kapasitas pembudidaya. Kajian ini memberikan kontribusi konseptual dalam memperkuat integrasi Blue Economy pada praktik budidaya ikan di Indonesia melalui tata kelola berbasis teknologi dan inklusivitas sosial

Abstract

Aquaculture intensification increases fish susceptibility to infectious diseases, prompting the search for natural alternatives to reduce dependence on synthetic chemicals. Bandotan leaves (Ageratum conyzoides L.) of the Asteraceae family contain secondary metabolites, including flavonoids, alkaloids, terpenoids, and saponins, with antibacterial, antioxidant, and immunomodulatory activities. This literature review aims to analyze the potential of bandotan leaves as a natural immunostimulant and antibacterial agent in aquaculture, focusing on their phytochemical content, mechanism of action, and safety. This study used a literature review method, conducting searches across national and international journal databases, university repositories, and research institute publications. The inclusion criteria included articles discussing the biological aspects, phytochemical content, antibacterial activity, immunomodulatory effects, physiological parameters, histology, and safety of bandotan leaves in the context of aquaculture. The results of the study showed that bandotan leaf extract effectively inhibited the growth of pathogenic bacteria in fish by disrupting cell membrane integrity and inhibiting bacterial enzymes. Its bioactive compounds enhance immune response, antioxidant activity, and reduce metabolic stress in fish. However, its application faces challenges in determining the optimal dosage, assessing histopathological effects, and managing potential respiratory distress at high concentrations. Further research is needed to optimize the formulation, understand the molecular mechanisms, and ensure the long-term safety of bandotan leaf use in sustainable fish farming systems.

Abstract

Thalassemia is an autosomal recessive genetic disorder that remains a significant public health concern in Indonesia; consequently, early detection of carriers is crucial to prevent the birth of children with thalassemia major. This study aims to analyze the risk of thalassemia among Biology students at the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Riau, utilizing a simplified laboratory screening approach. The research involved 30 students who participated in genetic risk questionnaires, hemoglobin level assessments using digital hemometers, and erythrocyte counts via hemocytometers. The findings revealed a questionnaire risk score of 0.07 (categorized as very low), a mean hemoglobin level of 12.73 g/dL, and an erythrocyte count of 5.22 million cells/µL, both of which fall within normal physiological ranges. These results indicate that the risk of thalassemia among Biology students at FMIPA Universitas Riau is remarkably low. Simple screening through questionnaires, hemoglobin levels, and erythrocyte counts can serve as an effective method for both educational purposes and the preliminary screening of thalassemia carrier risk in students.

Abstract

The Indo-Pacific region is the global center of marine biodiversity, home to more than 30% of the world's marine species. The order Decapoda, which comprises more than 17,000 species, plays significant ecological and economic roles in this region. This literature review aims to synthesize current knowledge on the genetic diversity and population structure of Decapoda in the Indo-Pacific and to identify the factors influencing these patterns. Molecular studies employing genetic markers such as mitochondrial DNA (mtDNA), microsatellites, and genomic sequencing indicate that Indo-Pacific Decapoda populations generally exhibit high haplotype diversity with relatively low nucleotide differentiation. Several factors, including larval dispersal capability, the duration of the planktonic phase, geographic and oceanographic barriers, and local adaptation to environmental conditions, shape population structure. Anthropogenic activities, particularly overexploitation, have led to declines in effective population size and genetic erosion in several commercially important species, such as Penaeus monodon and Scylla serrata. This review highlights the importance of integrating genetic data into sustainable fisheries management, including ecosystem-based stock assessment, periodic genetic monitoring, and the incorporation of genetic considerations in aquaculture and restocking programs to ensure the long-term sustainability of Decapoda populations in the Indo-Pacific region.

Abstract

Cosmos caudatus is a herb that benefits overall health. This study aimed to determine the effect of C. caudatus leaf supplementation in feed on blood glucose levels in catfish (Pangasianodon hypophthalmus) challenged with Aeromonas hydrophila. This study was conducted from March to August 2024 at the Marine Microbiology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The method used was an experimental design employing a completely randomized design (CRD) with four treatments and three replications: negative control (NC, no supplementation, no infection), positive control (PC, no supplementation, with A. hydrophila bacterial infection), supplementation with C. caudatus at doses of 10 g/kg (T1), 15 g/kg (T2), and 20 g/kg (T3) of feed, all tested against A. hydrophila. The fish fry used weighed 5.00 ± 1.00 g and were reared for 75 days in 100-L tanks integrated with an aquaponics system. The fish were fed the experimental feed for 60 days before challenge with A. hydrophila bacteria (10⁸ CFU/mL, intramuscular injection) and continued for 14 days after challenge. Blood glucose levels were measured at the beginning (day 1), day 30, pre-challenge (day 60), and post-challenge (day 75). The results showed that adding basil leaves to the feed affected blood glucose (P<0.05). The addition of C. Caudatus leaves maintained glucose homeostasis within the range of 68.33±10.59-79.67±7.77 mg/dL. These findings indicate that C. Caudatus supplementation effectively prevents hyperglycemia caused by A. hydrohila infection in striped catfish and suggest its potential as a natural immunostimulant and metabolic modulator in aquaculture

Abstract

Pangasianodon hypophthalmus is a stenohaline freshwater catfish that is increasingly exposed to salinity fluctuations due to tidal intrusion and the expansion of brackish water aquaculture. This study aimed to analyze the erythrocyte and leukocyte counts, as well as blood glucose levels, in P. hypophthalmus reared at different salinities. This study used a completely randomized design (CRD) with four treatments: 0 ppt salinity, 5 ppt salinity, 7 ppt salinity, and 9 ppt salinity, with three replicates. The hematological parameters analyzed included total erythrocytes, total leukocytes, and blood glucose. The results showed that salinity had a significant effect (p < 0.05) on total erythrocytes, total leukocytes, and blood glucose. A salinity of 5 ppt produced an optimal hematological profile, with a total erythrocyte count of 2.25 × 10⁶ cells/mm³, a total leukocyte count of 7.65 × 10⁴ cells/mm³, and blood glucose of 52.33 mg/dL. These findings indicate that a salinity of 5 ppt is the optimal salinity threshold for P. hypophthalmus aquaculture in brackish water environments and provide a physiological basis for adaptive aquaculture management amid changing environmental conditions

Abstract

Intensifikasi akuakultur sering kali diikuti dengan peningkatan stres dan kerentanan organisme budidaya terhadap penyakit, sehingga penggunaan antibiotik sintetis menjadi praktik umum. Namun, penggunaan secara berlebihan menimbulkan berbagai permasalahan, seperti resistensi bakteri, residu pada produk perikanan, dan dampak negatif terhadap lingkungan. Oleh karena itu, diperlukan alternatif pengendalian penyakit yang lebih aman dan berkelanjutan, salah satunya melalui pemanfaatan fitofarmaka. Daun kenikir (Cosmos caudatus Kunth) merupakan tanaman yang diketahui mengandung berbagai senyawa bioaktif, seperti flavonoid, fenolik, saponin, tanin, dan alkaloid, yang berpotensi sebagai imunostimulan alami. Kajian ini bertujuan untuk menelaah potensi daun kenikir sebagai imunostimulan dalam akuakultur berdasarkan studi-studi terdahulu. Metode yang digunakan adalah kajian literatur dengan mengumpulkan dan menganalisis hasil penelitian terkait kandungan fitokimia, aktivitas biologis, mekanisme kerja, serta aplikasi daun kenikir pada organisme akuakultur. Hasil kajian menunjukkan bahwa senyawa bioaktif daun kenikir memiliki aktivitas antioksidan, antibakteri, dan imunomodulator yang mampu meningkatkan respons imun nonspesifik, ketahanan terhadap penyakit, pertumbuhan, serta sintasan ikan dan udang budidaya. Dengan demikian, daun kenikir berpotensi dikembangkan sebagai alternatif fitofarmaka yang aman, efektif, dan ramah lingkungan untuk mendukung sistem akuakultur berkelanjutan, meskipun masih diperlukan penelitian lanjutan terkait dosis optimal, metode aplikasi, dan keamanan jangka panjang
