Selenium is an essential micromineral needed in small amounts in the body, but affects themetabolism and health of aquaculture organisms. This study aimed to analyze the growth of catfish(Clarias gariepinus) supplemented with selenium peptide through the coating method on feed. Therewere four different treatments, namely K (feed without selenium peptide), A (feed with seleniumpeptide of 3 g kg-1feed), B (feed with selenium peptide of 6 g kg-1feed), and C (feed with seleniumpeptide of 9 g kg-1feed). A total of 15 catfish with weight of 21.80 ± 0.29 g were kept in an aquariumat dimension of 90 x 40 x 45 cm3filled with water at a depth of 35 cm (Volume of 108 L) for 45 days.Fish were fed three times a day at satiation. Water quality management was carried out by the use ofsimple filtration in the container and water replacement to ensure optimum water quality values forcatfish growth. The results showed that the growth performance parameters (final biomass, finalindividual weight, survival rate, and daily growth rate) of catfish fed with selenium peptide weresignificantly different (p<0.05) from catfish fed without selenium peptide. Based on this study, thebest dose of feed additive in catfish feed was 3 g kg-1of feed.Keyword: Clarias gariepinus, selenium peptide, growthABSTRAKSelenium termasuk ke dalam mikromineral esensial yang dibutuhkan dalam jumlah sedikit padatubuh, akan tetapi mampu berpengaruh terhadap metabolisme dan kesehatan organisme akuakultur.Penelitian ini bertujuan menganalisis pertumbuhan ikan lele (Clarias gariepinus) yang ditambahselenium peptida melalui metode coating pada pakan.

Aquaponics and biofloc are aquaculture techniques for reducing nitrogenous waste with less water exchange. Aquaponics reduces nitrate (NO3-) through the role of vegetable plants, while biofloc assimilates ammonia (NH4+) through the role of floc-forming bacteria. In this study a collaboration was designed between aquaponics and biofloc called aquabioponics. This study was conducted to evaluate the performance of tilapia production, as well as to observe the dynamics of P, K, Ca, Mg, Fe, Mn, Zn, and Cu minerals formed in the system. This study used a completely randomized design with three treatments and three replications, namely aquaponics (AP), biofloc (BF), and aquabioponics (AB). The AP integrates water in fish tank with vegetable, and does not use additional organic carbon sources. BF uses the addition of an organic carbon source, but does not integrate vegetables. Meanwhile, AB uses the addition of an organic carbon source (half of the dose in BF) and also integrates vegetables. Nile tilapia Oreochromis niloticus with a length of 5.56 ± 0.13 cm and a weight of 5.92 ± 0.47 g totaling 200 individuals were monitored for 60 days in a fiber tank containing 500 L of water in each treatment. The vegetables used in the AP and AB are Pok Choi which is harvested every 30 days. In this study, aquabioponics is a system that produces the best tilapia production performance. The minerals Ca, Mg, Mn, Zn, and Cu are thought to be essential in aquaponics and aquabioponics, while Mg is thought to be essential in bioflocs.

Bonylip barb fish Osteochilus hasselti is traditionally cultivated as a by-product in a polyculture system due to the problem of seed availability. The increase in local market demand for O. hasselti has not been met due to the low productivity of the growers. In an effort to increase the availability of fish seeds, intensification at the nursery stage has the potential to be effective in overcoming the limitations of land and water for cultivation. The aquaponic system can maximize yields through vertical use of space and also overcome water limitations with a recirculation system. This study aimed to evaluate the effectiveness of the aquaponics system on the intensification of O. hasselti nursery. The treatment tested was the stocking density of O. hasselti at an initial length of 4.28 ± 0.52 cm and a weight of 0.73 ± 0.29 g as many as 100 ind./m2, 150 ind./m2, and 200 ind./m2 in an aquaponic system with bok choy plants (Brassica rapa subsp. chinensis). Bonylip barb fish nursery for 30 days using aquaponic system showed that the treatment resulted in maximum survival with absolute length growth, feed conversion ratio, coefficient of variation in length and weight which were not significantly different (P>0.05). At densities above 100 ind./m2, the absolute weight growth value and the specific growth rate were higher. Overall, it can be concluded that the aquaponics system can be used for O. hasselti nursery at high stocking densities with the best production performance at a stocking density of 200 ind./m2.

由于种子可得性的问题，Bonylip有倒刺鱼Osteochilus hasselti传统上是作为混养系统的副产品栽培的。由于种植者的生产力低下，当地市场对O. hasselti的需求并未得到满足。为了增加鱼类种子的供应，苗圃阶段的集约化有可能有效地克服耕种土地和水的限制。水培系统可以通过垂直利用空间来最大限度地提高产量，也可以通过再循环系统克服水的限制。本研究旨在评价水培系统对哈塞草苗圃的强化效果。试验处理是在初始长度为4.28±0.52 cm、重量为0.73±0.29 g时，在与小白菜(Brassica rapa subsp.)共生的条件下，哈塞草的放养密度分别为100、150和200个/m2。对)。水培系统育苗30 d的结果表明，该处理对大褐刺鱼的成活率影响最大，其绝对体长、饲料系数、体长和体重变异系数均无显著差异(P>0.05)。密度大于100 ind./m2时，绝对生长值和比生长率较高。综上所述，在高放养密度条件下，水培系统可用于黄颡鱼苗圃，放养密度为200个/m2时生产性能最佳。关键词:鱼密度，生长，集约化，小白菜abstract: Ikan nilem, Osteochilus hasselti, dibudidayakan secara，传统的小白菜产品，采样和dalam系统，公共文化karena masalah, ketersediaan benh。Peningkatan permintaan pasar local terhadap nilem belum dapat dipenuhi karena rendahnya productivitas pembesaran。Dalam upaya mengatasi keterbatasan lahan dan air untuk budidaya。Perkembangan technologii buddidaya登干系统akuaponik dapat memaksimalkan hasil melalui pmanfaatan runang secara垂直登干系统keterbatasan空气登干系统ressirkulasi。Penelitian ini bertujuan为她mengevaluasi efektivitas sistem akuaponik terhadap intensifikasi pendederan鱼nilem。Perlakuan yang diuji adalah padat tebar ikan nilem dengan panjang 4,28±0.52 cm丹bobot 0,73±0.29 g sebanyak 100 ekor/m2, 150 ekor/m2，丹200 ekor/m2帕达系统akuaponik dengan tanaman pak choi Brassica rapa亚种。对。Pendederan nilem selama 30 hari dalam系统akuaponik memperlihatkan bahwa perlakuan menghasilkan kelangsungan hidup serta panjang dan bobot yang tidak berbeda nyata (P> 0.05)。帕达·帕达丹·迪达尔(100 ekor/m2)， perperoleh nilai pertumbuhan bobot mutlak danlaju pertumbuhan specfik yang lebih tinggi。Secara keseluruhan, dapat dispulpulkan bahwa system, akuaponik, dapat digunakan, untuk pendederan, ikan nilem, padat tebar, yang tinggi, dengan, kinerja, producksi, terbaik, padat tebar 200 ekor/m2。Kata kunci: padat tebar, pertumbuhan, intensifikasi, pak choi

Aquaponics is the cultivation of fish and plants in a series of systems, either in one container or in separate containers, by paying attention to the balance between fish, plants, and aquatic microorganisms. One of the obstacles in aquaponic activities is that vegetable growth is not optimal due to a lack of dissolved nutrients, so further research is needed to make better plant growth. This study aimed to evaluate catfish and water spinach growth performance in an aquaponic system by adding AB mix nutrients at different fish stocking densities. This study used a completely randomized design with three differences in stocking densities of catfish (150 fish/m3, 200 fish/m3, and 250 fish/m3) as test animals with four replications where AB mix was added to each treatment. The growth performance of catfish is better in control with a stocking density of 250 fish/m3 and without adding nutrients. The growth performance of catfish decreased with the addition of AB mix nutrients, while the growth of water spinach was better. The growth rate of catfish without adding AB mix nutrients was higher than in other treatments. In contrast, all treatments with the addition of AB mix increased the growth performance of water spinach, with the stocking density of catfish not affecting the growth of water spinach plants. Keywords: aquaponics, water spinach, catfish, growth ABSTRAK Akuaponik merupakan budidaya ikan dan tanaman dalam satu rangkaian sistem, baik dalam satu wadah maupun dalam wadah terpisah dengan memperhatikan keseimbangan antara ikan, tanaman dan mikroorganisme perairan. Salah satu kendala sistem akuaponik adalah pertumbuhan sayuran yang tidak optimal karena kurangnya nutrisi terlarut. Tujuan dari penelitian ini untuk mengevaluasi performa pertumbuhan lele dan kangkung dalam sistem akuaponik dengan penambahan nutrisi AB mix dan pada padat tebar ikan yang berbeda. Penelitian menggunakan rancangan acak lengkap dengan tiga perbedaan padat tebar ikan lele (150 ekor/m3, 200 ekor/m3, dan 250 ekor/m3) sebagai hewan uji sebanyak empat ulangan di mana nutrien AB mix ditambahkan disetiap perlakuan. Kinerja pertumbuhan ikan lele lebih baik pada perlakuan kontrol dengan padat tebar 250 ekor/m3 dan tanpa penambahan nutrisi AB mix. Performa pertumbuhan ikan lele menurun dengan adanya penambahan nutrisi AB mix, sedangkan pertumbuhan tanaman kangkung lebih baik.

鱼菜共生是通过关注鱼、植物和水生微生物之间的平衡，在一系列系统中养殖鱼类和植物，无论是在一个容器中还是在单独的容器中。水培活动的障碍之一是由于缺乏溶解性营养物质而导致蔬菜生长不理想，因此需要进一步研究以使植物更好地生长。本试验旨在通过在不同放养密度下添加AB混合营养物，评价鱼养系统中鲶鱼和水菠菜的生长性能。本研究采用完全随机设计，将三种不同放养密度的鲶鱼(150条/m3、200条/m3和250条/m3)作为试验动物，在每个处理中添加AB混合物，共4个重复。在放养密度为250尾/m3、不添加营养的情况下，鲶鱼的生长性能较好。添加AB混合营养物质后，鲶鱼的生长性能下降，而水菠菜的生长性能较好。不添加AB混合营养的鲶鱼生长速率高于其他处理。相反，添加AB混合料的各处理均提高了水菠菜的生长性能，鲶鱼的放养密度对水菠菜植株的生长没有影响。【关键词】水培共生;水菠菜;鲶鱼;健康系统，健康系统，健康系统，健康系统，健康系统，健康系统，健康系统。Tujuan dari penelitian ini untuk mengevaluasi pertumbuhan leele dankangkung dalam系统akuaponik dengan penambahan nutrisi AB混合dan padat padat tebar ikan yang berbeda。Penelitian menggunakan ranancan acak lengkap dengan tiga perbedaan and padat tebarkan leele (150 ekor/m3, 200 ekor/m3, 250 ekor/m3) sebagai hewan uji sebanyak empat ulangan di mana nutrien AB mix ditambahkan disetiap perlakuan。金花pertumbuhan ikan leele lebih baik pada perlakuan control dengan padat tebar 250 ekor/m3丹tanpa penambahan nutrisi AB混合料。pertumbuhan ikan leele menurun dengan adanya penambahan nutrisi AB mix, sedangkan pertumbuhan tanaman kangkung lebih baik。Laju pertumbuhan ikan lele dengan tanpa penambahan nutrisi AB mix lebih tinggi dibandingkan perlakuan lainnya, sedangkan semua perlakuan dengan penambahan AB mix meningkatkan pertumbuhan tanaman kangkung dengan jumlah padat tebar ikan lele tidak berpengaruh pada pertumbuhan tanaman kangkung。Kata kunci: akuaponik, kangkung, lele, pertumbuhan

One of the obstacles in aquaponic activities is that vegetable growth is not optimal due to a lack of dissolved nutrients, so further research is needed to make better plant growth. This study aimed to evaluate catfish and water spinach growth performance in an aquaponic system by adding AB mix nutrients at different fish stocking densities. This study used a completely randomized design with three differences in stocking densities of catfish (150 fish/m3, 200 fish/m3, and 250 fish/m3) as test animals with four replications where AB mix was added to each treatment. The growth performance of catfish is better in control with a stocking density of 250 fish/m3 and without adding nutrients. The growth performance of catfish decreased with the addition of AB mix nutrients, while the growth of water spinach was better. The growth rate of catfish without adding AB mix nutrients was higher than in other treatments. In contrast, all treatments with the addition of AB mix increased the growth performance of water spinach, with the stocking density of catfish not affecting the growth of water spinach plants. \u0000Keywords: aquaponics, water spinach, catfish, growth \u0000 \u0000ABSTRAK \u0000Akuaponik merupakan budidaya ikan dan tanaman dalam satu rangkaian sistem, baik dalam satu wadah maupun dalam wadah terpisah dengan memperhatikan keseimbangan antara ikan, tanaman dan mikroorganisme perairan.

This study aimed to evaluate the physiological performance and status of comet goldfish (Carassius auratus) in aquascape system with different aquatic plant species. Comet goldfish (6.5 ± 0.073 cm length and 9.1 ± 0.1 g weight in average) were reared in aquaria with 10 fish/L density per aquarium for 45 days. The results obtained a positive correlation between SR value and SGR value, followed by a significant different value among the treatments applied (P<0.05). Based on the total chromatophore cells, comet goldfish reared in aquarium containing aquatic plants had a significant different (P<0.05) on the total chromatophore cells compared to aquarium without aquatic plants (control). After blood glucose test, comet goldfish reared with aquatic plants consistently showed a lower blood glucose level than without aquatic plants. The liver SOD level of comet goldfish obtained a significant different value between fish reared with aquatic plants and without aquatic plants, while the MDA value on all treatments was insignificantly different. Also, increased total erythrocytes, total leucocytes, hemoglobin, and hematocrit were found on comet goldfish reared with aquatic plants. This study concludes that aquatic plants in rearing system can improve the survival rate, specific growth rate, health status of comet goldfish due to mutualistic symbiosis discovered between fish and aquatic plants.

Coffee by-products can be used as a feed additive for red Nile tilapia. This study aimed to evaluate the utilization of different dietary coffee husk supplementation dosages on the growth and antioxidative activity of red Nile tilapia (Oreochromis sp.). This study was designed following the completely randomized design experimental method, containing five dietary supplementation treatments, namely P0 (control, 0%), P1 (1%), P2 (2%), P3 (3%), and P4 (4%). Fish were reared for 8 weeks and fed three times a day. Parameters observed contained growth performance and antioxidative activity. The results showed that dietary coffee husk powder supplementation treatments provide higher growth than control treatment. Based on blood chemicals, coffee husk-supplemented diets could enhance the HDL content and reduce cholesterol, triglycerides, and LDL (P<0.05). Superoxide dismutase enzyme was also found higher in coffee husk supplemented diets than in control diet (P<0.05). The MDA level decreased on the coffee husk-supplemented diet treatment and was lower than the control treatment (P<0.05). Dietary supplementation of coffee husk could positively affect liver performance, based on hepatosomatic index and glycogen level.

Vibrio alginolyticus which becomes the main cause of vibriosis disease in grouper culture and causes great economic loss in Asian aquaculture industries. This study investigated the antibacterial activity of clove extract and the effect of adding clove powder to the diet on survival cantang grouper infected with V. alginolyticus. The clove extraction used a maceration method. Two dose levels of clove powder were used, namely 10 and 15 g kg−1. The control treatments without clove powder supplementation contained positive control (CP) and negative control treatment (CN). The results found that the clove extract contained five major compounds. The highest compound was phenol, 2-methoxy-4-(2-propenyl)-Eugenol (64.07%). Phytochemical analysis of clove extract contained phenolics, flavonoids, and tannins at (28.53 ± 0.00) mg/g, (0.38 ± 0.00) mg/g, and (0.15 ± 0.00) %, respectively. The diameter of the clove extract inhibition zone was significantly different (P < 0.05) in all treatments. The Scanning Electron Microscopy (SEM) result presents that the clove extract can alter the V. alginolyticus cell morphology. The dietary supplementation of clove powder improves the survival rate significantly higher (P<0.05) post-challenge test. The conclusion of this research is that clove extract has antibacterial activity that can inhibit growth and cause cell morphological damage to V. alginolyticus. The application of clove powder at a dose of 15g kg-1 was able to improve the survival value which was a higher post-challenge test.

The aim of the study is to test the effectiveness of adding various paraprobiotic doses of Bacillus sp. NP5 through feed in improving the immune responses and resistance of tilapia juvenile (Oreochromis niloticus) to infection of Streptococcus agalactiae. Bacillus sp. NP5 paraprobiotic was produced through heat-inactivation at 95°C for 1 h. This study used a completely randomized design, which consisted of four treatments with three repetitions. The test feed was enriched with 1% paraprobiotic with a density of 108, 109, and 1010 CFU ml-1. The tilapia juvenile (10.29 ± 0.22 g) were reared for 30 days and on day 31, the fish was challenge tested with S. agalactiae (107 CFU ml-1) injected by intraperitoneal route unless the negative control was injected with PBS. The results of this study showed significantly improved growth performances and immune responses (P<0.05), compared to the control group after 30 days of paraprobiotic Bacillus sp. NP5 administered. The increased of immune responses in paraprobiotic of Bacillus sp. NP5 showed a higher survival rate (P<0.05), than positive control after the challenge tested with S. agalactiae. Administration of paraprobiotic Bacillus sp.
