The feed prices affect feed grade; the cheaper the feed price, the lower the quality. This low feed quality may improve its quality by supplementing <em>Chlorella vulgaris</em>. Therefore, this study aimed to determine the level of supplementation of <em>C. vulgaris</em> meal in the feed that produces the best growth performance in striped catfish juveniles. A completely randomized design with three treatments and three replications was used in this experiment. The treatments were various levels of <em>C. vulgaris</em>, namely 0%, 1.5%, and 3%. <em>C. vulgaris</em> meal was added to the commercial feed (26-28% protein) according to the treatment with the coating method. The test feed was fed to striped catfish juveniles (6.66 ± 0.04 g in average weight) reared in an aquarium containing 55 L of water at a density of 20 juveniles, at satiation in the morning, afternoon, and evening for 50 days of the rearing period. Survival rate and hepatosomatic indices of the striped catfish were not affected by various supplementation levels of <em>C. vulgaris</em> meal (P>0.05), but the values of feed consumption, specific growth rate, feed conversion, and protein efficiency ratio of the striped catfish (P<0.05). Supplementation of 3.5% <em>C. vulgaris</em> meal in feed resulted in the best growth performance for striped catfish.</span></div>2023-11-08T00:00:00+01:00Copyright (c) 2023 Arwana: Jurnal Ilmiah Program Studi Perairanhttp://www.journal.umuslim.ac.id/index.php/jipsbp/article/view/1976Effectiveness of Chlorella sp. in phytoremediation of different wastewater in North Aceh2023-05-10T03:58:18+02:00Rachmawati Rusydirachmawati.rusydi@unimal.ac.idMahdaliana Mahdalianamahdaliana@unimal.ac.idIsra Ambiaisra.170330075@mhs.unimal.ac.idMuliani Mulianimuliani@unimal.ac.idPrama Hartamiprama.hartami@unimal.ac.id<div><em><span lang="EN-US">Chlorella</span></em></div> <div><span lang="EN-US"> sp. is microalgae species used to treat wastewater and can grow and develop well inside contaminated environments by interweaving symbiosis with bacterial decomposers.

To date there has been no effort to rear Banggai cardinalfish on a commercial scale, so that fish are still mainly captured from the wild. Therefore, efforts are being made to develop <em>ex-situ</em> Banggai cardinalfish culture using different types of natural feed. This research aimed to determine the best type of natural feed to promote the growth and survival of juvenile Banggai cardinalfish. The research was conducted during December 2021-January 2022, at the Central Sulawesi Provincial Marine Affairs and Fisheries Service Hatchery, in Mamboro Village, Palu City. The study used 3 treatments with 6 replicates each: A (<em>Artemia</em>), B (<em>Cullex</em>), and C (<em>Tubifex</em>). The use of different natural feeds had a significant effect on net weight gain but did not have a significant effect on daily growth rate and net growth in length.

Adding cassava leaf meal and multivitamin vitaliquid to the feed can increase the high appetite of fish and accelerate the growth of saline tilapia. This research was implemented to find the effectiveness of multivitamin vitaliquid on the growth and survival rate of saline tilapia (Oreochromis niloticus). The rule used is an experiment with a Completely Randomized Design (CRD), four treatments and six replications. Data showed that the largest absolute weight growth was achieved by P4 of 4.98 ± 3.14 grams, while the smallest result was at P1 which was 2.78 ± 0.21 grams. The greatest absolute length growth was achieved at P3 resulting in a length of 2.3 ± 0.86 cm, while the smallest result was at P1 which was 1.3 ± 0.41. The highest specific growth rate was achieved at P3 11.35 ± 0.57%, while the lowest was at P2 of 9.53 ± 1.58%. The highest survival rate of saline tilapia was found in P1 at 95%, while the lowest was found in P3 and P4 which had no different results, 81.7%. The effectiveness of multivitamin vitaliquid in commercial feed given cassava leaf flour in terms of absolute weight growth, absolute length growth, specific growth rate and survival of saline tilapia fry is very effective compared to just being given pellet feed.</p>2023-11-14T00:00:00+01:00Copyright (c) 2023 Arwana: Jurnal Ilmiah Program Studi Perairanhttp://www.journal.umuslim.ac.id/index.php/jipsbp/article/view/2027Chemical and antioxidant characteristics on rice crackers fortified with seaweed Eucheuma cottoni and dayak onion2023-06-20T10:38:47+02:00Christine Dyta Nugraenichdyta@gmail.comDena Pramita Dewidenapd93@gmail.comTuty Alawiyahtutyalawiyah@borneo.ac.idGazali Salimaxza_oke@yahoo.comTri Paus Hasiholan Hutapeahutapea2606@gmail.com<p>This study aims to observe the addition of seaweed and Dayak onions to rice crackers on the nutritional content and antioxidant activity.

The goal of this study was to ascertain how adding viterna plus supplements to the feed at various doses would affect the growth of milkfish fry. With 5 treatments and 4 replications, the method used a non-factorial Completely Randomized Design (CRD). Absolute length, weight gain, feed conversion ratio, and specific growth rate all demonstrated a significant effect in the ANOVA test results (P 0.05). However, there was a significant effect on survival (P> 0.05). The best absolute growth in weight and length was demonstrated by a dose of 20 ml/kg in feed, or 0.59 gr and 1.77 cm, respectively. With a feed conversion ratio of 1.10, the specific growth rate at this dose was 1.47% per day. In addition, a dose of 15 ml/kg of feed resulted in the best survival at P3 of 94.2%.

Four <em>Artemia</em> sp. enrichments with different doses of FOS (P0: 0%, P1: 1.3%, P2: 1.5%, P3: 1.7%) were fed to vannamei larvae. The absolute weight, absolute length, daily growth rate, and protease activity of enrichment treatments were higher (P<0.05) than without enrichment. There are no differences (P>0.05) in protease activity of vannamei larvae between P2 and P3 treatment. <em>Artemia</em> sp. enrichment using different doses of FOS can increase the growth and protease enzyme activity of white shrimp larvae. The growth, protease and amylase activity of vaname larvae are improved with increasing FOS enrichment dose on <em>Artemia </em>sp. The FOS enrichment dose of 1.7% is the best because it can produce the best growth performance, survival rate and digestive enzyme activity.</span></div>2023-11-30T00:00:00+01:00Copyright (c) 2023 Arwana: Jurnal Ilmiah Program Studi Perairanhttp://www.journal.umuslim.ac.id/index.php/jipsbp/article/view/2250Community structure of phytoplankton in Downstream of the Segedong River, Kubu Raya Regency, West Kalimantan2023-10-06T12:10:03+02:00Syifa Ulva Nara Ditasyifaulvanaradita23@gmail.comEntin Daningsihentin.daningsih@fkip.untan.ac.idWolly Candramilawolly.candramila@fkip.untan.ac.id<p><span style="font-weight: 400;">The Segedong River flows between the Tanjung Prapat Muda Mangrove Protected Forest in Kubu Raya Regency.

The study was carried out in 2022 within the aquatic territory of Aceh Jaya Regency. The lobster fishermen at the research area employ gill nets as their fishing gear. The data collection approach involves doing direct field observations and performing identifications in the laboratory. The analysis of the data is then carried out using descriptive techniques. During lobster fishing operations, fishermen engage in a daily routine that involves setting and hauling the fishing gear once a day. This process lasts for 16 hours and includes lifting the catch onto land. Analysed data on the six species of lobster (<em>Panulirus</em> spp) taken by lobster fisherman, specifically <em>Panulirus penicillatus, P. longipes, P. ornatus, P. polyphagus, P. versicolor,</em> and <em>P. homarus</em>. All six varieties of lobster have different morphological characteristic based on the color and shape of the <em>maxilliped</em>.</span></div>2023-11-30T00:00:00+01:00Copyright (c) 2023 Arwana: Jurnal Ilmiah Program Studi Perairan
