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 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. \u0000Keywords: fish density, growth, intensification, pak choi \u0000  \u0000ABSTRAK \u0000  \u0000Ikan nilem Osteochilus hasselti dibudidayakan secara tradisional sebagai produk sampingan dalam sistem polikultur karena masalah ketersediaan benih.

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.

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 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. \u0000  \u0000Keyword: antibacterial activity, clove, grouper, phytochemical, Vibrio alginolyticus","PeriodicalId":32090,"journal":{"name":"Jurnal Akuakultur Indonesia","volume":"GE-19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84609262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
