Evaluasi Pemijahan Induk Ikan Baung (Mystus nemurus) Yang Diberi Pakan Keong Mas (Pomacea canaliculata)
Full text linkThis study aims to evaluate the effects of feeding golden apple snails (Pomacea canaliculata) on the growth and gonad development of prospective broodstock of Asian Redtail Catfish (Mystus nemurus). The background of the research is based on the declining population of Asian Redtail Catfish in the wild due to overexploitation, necessitating effective aquaculture efforts with attention to broodstock nutrition. Golden apple snails were chosen as an alternative feed due to their high protein and nutrient content, as well as their abundant availability and cost-effectiveness. The research method was experimental, comparing two treatment groups: the first group was fed golden apple snails, and the second group was given commercial pellets as a control. The observed parameters included egg diameter, fecundity, fertilization rate (FR), hatching rate (HR), survival rate (SR), and water quality. The fish were reared for three months in aquaculture ponds with periodic water quality monitoring. The results showed that feeding golden apple snails had a significantly positive impact on the reproductive performance of Asian Redtail Catfish. The snail-fed group exhibited higher fecundity (averaging 130,678 eggs) compared to the pellet-fed group (91,025 eggs). Additionally, the snail-fed group had superior FR (92%), HR (87%), and SR (79%) compared to the pellet-fed group (FR 88%, HR 81%, SR 76%). The egg diameter from snail-fed broodstock was larger (2.01 ± 0.14 mm) than that of the pellet-fed group (1.61 ± 0.04 mm), indicating better egg quality. Based on these findings, it was concluded that golden apple snails are effective as an alternative feed for enhancing the reproductive productivity of Asian Redtail Catfish. The nutrients in the snails, particularly protein, fats, and essential amino acids, play a crucial role in supporting gonad development and egg quality. This study recommends the use of golden apple snails in Asian Redtail Catfish aquaculture, with the suggestion that further research be conducted to determine the optimal dosage and feeding strategy. The implementation of these findings is expected to support sustainable Asian Redtail Catfish farming and improve the availability of high-quality fry.Penelitian ini bertujuan mengevaluasi pengaruh pemberian pakan keong mas (Pomacea canaliculata) terhadap pertumbuhan dan perkembangan gonad calon induk ikan baung (Mystus nemurus). Latar belakang penelitian didasari oleh menurunnya populasi ikan baung di alam akibat eksploitasi berlebihan, sehingga diperlukan upaya budidaya yang efektif dengan memperhatikan aspek nutrisi induk. Keong mas dipilih sebagai pakan alternatif karena kandungan protein dan nutrisinya yang tinggi, serta ketersediaannya yang melimpah dan ekonomis. Metode penelitian dilakukan secara eksperimental dengan membandingkan dua kelompok perlakuan: kelompok pertama diberi pakan keong mas dan kelompok kedua diberi pelet komersial sebagai kontrol. Parameter yang diamati meliputi diameter telur, fekunditas, Fertilization Rate (FR), Hatching Rate (HR), Survival Rate (SR) dan kualias air. Pemeliharaan dilakukan selama tiga bulan di kolam budidaya dengan pengontrolan kualitas air secara berkala. Hasil penelitian menunjukkan bahwa pemberian keong mas memberikan dampak positif yang signifikan terhadap kinerja reproduksi ikan baung. Kelompok yang diberi keong mas menghasilkan fekunditas lebih tinggi (rata-rata 130.678 butir telur) dibandingkan pelet (91.025 butir). Selain itu, parameter FR (92%), HR (87%), dan SR (79%) pada kelompok keong mas juga lebih unggul daripada kelompok pelet (FR 88%, HR 81%, SR 76%). Diameter telur yang dihasilkan oleh induk yang diberi keong mas lebih besar (2,01 ± 0,14 mm) dibandingkan pelet (1,61 ± 0,04 mm), menunjukkan kualitas telur yang lebih baik. Berdasarkan hasil tersebut, disimpulkan bahwa keong mas efektif sebagai pakan alternatif untuk meningkatkan produktivitas reproduksi ikan baung. Nutrisi dalam keong mas, terutama protein, lemak, dan asam amino esensial, berperan penting dalam mendukung perkembangan gonad dan kualitas telur. Penelitian ini merekomendasikan penggunaan keong mas dalam budidaya ikan baung, dengan catatan perlu dilakukan penelitian lanjutan untuk menentukan dosis optimal dan strategi pemberian pakan yang tepat. Implementasi hasil penelitian ini diharapkan dapat mendukung budidaya ikan baung yang berkelanjutan dan meningkatkan ketersediaan benih berkualitas
REVIEW: COMPARATIVE SYSTEM ANALYSIS OF OYSTER (Crassostrea sp) BREEDING IN JAPAN AND INDONESIA
Full text linkOysters (Crassostrea sp.) are high-value aquaculture commodities with significant economic and ecological potential. Japan and Indonesia are both maritime countries with vast marine resources, yet they differ considerably in their oyster farming systems. This study aims to conduct a comparative analysis of oyster cultivation systems in the two countries, focusing on farming methods, technology, environmental management, policy support, and productivity. A qualitative descriptive approach was employed through a literature review of various scientific sources and secondary data published over the past ten years.

Full text linkThe high cost and limited availability of fishmeal in aquaculture feed formulations have prompted the search for sustainable and affordable alternative protein sources. This study aimed to evaluate the effects of substituting fishmeal with silk worm (Tubifex sp.) meal on the growth performance, feed utilization, and survival rate of Nile tilapia (Oreochromis niloticus) fry. A completely randomized design (CRD) was used with four dietary treatments: P1 (control, 0% Tubifex), P2 (15%), P3 (25%), and P4 (35%), each with three replications. Fish were fed twice daily for 30 days, and growth parameters were measured weekly. Results showed that the inclusion of Tubifex meal significantly improved the final weight, specific growth rate (SGR), average daily gain (ADG), and feed efficiency (FE), particularly in P3 and P4. The highest SGR (2.28%/day), ADG (0.016 g/day), and FE (61.93%) were recorded in the P4 group. Survival rate also improved, reaching 82.22% in P4 compared to 51.11% in the control. Water quality parameters remained within optimal ranges, indicating no adverse environmental impact from Tubifex inclusion. The findings suggest that Tubifex meal is a viable protein source that can replace fishmeal by up to 35% in tilapia fry diets. Its application offers nutritional, economic, and ecological benefits, making it a promising component in sustainable aquafeed development.Tingginya biaya dan keterbatasan ketersediaan tepung ikan dalam formulasi pakan budidaya mendorong pencarian sumber protein alternatif yang berkelanjutan dan terjangkau.
