Ikan membutuhkan pakan dalam pertumbuhan dan kelangsungan hidupnya.  Pakan ikan adalah komponen paling penting dalam budidaya ikan.  Pakan yang berkualitas bagi ikan adalah pakan yang mudah dicerna, tidak mengandung racun, dan mengandung gizi yang tinggi.  Kulit  buah manggis dapat dijadikan pakan ikan dalam meningkatkan pertumbuhan dan kelangsungan hidup ikan yang dibudidayakan karena mengandung senyawa xantone yang cukup kuat sebagai antioksidan, antiproliferartif, dan antimicrobial.  selain itu mengandung flavonoid, saponin, alkaloid, triterpenoid, tanin, dan polifenol (Suksamrarn, 2003; Mardawati et al., 2008; Puspitasari et al., 2013).  Komposisi tepung kulit buah manggis yaitu air 9%, abu 2,58%, protein 2,69%, serat kasar 30,05%, gula total 6,92%, dan lainnya (tanin, lemak) 48,76%. Kegiatan penerapan penelitian Unggulan Perguruan Tinggi ini bertujuan untuk mengetahui pengaruh penambahan tepung kulit buah manggis terhadap pertumbuhan dan kelangsungan hidup ikan nila (Oreochromis niloticus).  Waktu pelaksanaan penelitian selama 1 bulan dari tanggal 08 Agustus sampai 10 September 2020 di Kampung Nahepese Kecamatan Manganitu.  Prosedur kerja penelitian meliputi beberapa tahap yaitu persiapan pakan uji, persiapan wadah pemeliharaan, persiapan ikan uji, dan pemeliharaan ikan uji.  Ikan uji yang digunakan dalam penelitian ini adalah ikan nila berukuran 3-5 cm sebanyak 180 ekor dimana masing-masing wadah didistribusikan  20 ekor ikan.  Sedangkan bahan uji yang dipakai adalah tepung kulit buah manggis yang ditambahkan dalam tepung pelet kemudian dicampurkan menjadi merata lalu ditambahkan air secukupnya, dicetak dan dijemur.  Laju pertumbuhan harian tertinggi ikan nila selama 30 hari pemeliharaan terdapat pada perlakuan B.  Sintasan hidup ikan nila pada kontrol dan perlakuan B yaitu 100%, yang artinya semua ikan uji yang dipelihara hidup semua.  Sedangkan pada perlakuan A yaitu 95%, dimana ada 1 ekor ikan yang meloncat keluar happa.   Fish need feed for growth and survival.  Fish feed is the most important component in fish farming.  Quality feed for fish is food that is easily digested, does not contain toxins, and contains high nutrition.  Mangosteen rind can be used as fish feed in increasing the growth and survival of cultivated fish because it contains xanthone compounds which are strong enough as antioxidants, antiproliferarts, and antimicrobials.  besides containing flavonoids, saponins, alkaloids, triterpenoids, tannins, and polyphenols (Suksamrarn, 2003; Mardawati et al., 2008; Puspitasari et al., 2013).  The composition of mangosteen rind flour is 9% water, 2.58% ash, 2.69% protein, 30.05% crude fiber, 6.92% total sugar, and 48.76% others (tannins, fat). This research application activity of Higher Education Excellence aims to determine the effect of adding mangosteen rind flour to the growth and survival of tilapia (Oreochromis niloticus).  The time for conducting the research is 1 month from August 8 to September 10 2020 in Nahepese Village, Manganitu District. The research work procedure includes several stages, namely preparation of test feed, preparation of maintenance containers, preparation of test fish, and rearing of test fish.  The test fish used in this study were 180 tilapia fish measuring 3-5 cm in which 20 fish were distributed in each container.  While the test material used is mangosteen rind flour which is added to the pellet flour then mixed evenly and then added with enough water then printed and dried. The highest daily growth rate of tilapia for 30 days of maintenance was found in treatment B. The survival rate of tilapia in control and treatment B was 100%, which means that all of the tested fish that were reared were all alive.  Whereas in treatment A, it was 95%, where 1 fish jumped out of the happa.

Catfish has various advantages, including fast growth, high adaptability to the environment, delicious taste, and high nutritional content.  As a source of nutrition for reared fish, feed is a factor that plays a very important and decisive role in the success of fish farming.  The research aims to determine the effect of feeding frequency on the growth and survival of sangkuriang catfish larvae (C. gariepinus). The study was conducted from June to July 2020 at the Abelisawa Fish Seed Center (BBI), Sampara District, Konawe Regency, South East Sulawesi Province using a Completely Randomized Design with three frequencies of feeding treatment, namely treatment A feeding twice a day, treatment B feeding 3 times a day and treatment C feeding 4 times a day with 3 replications.  Data were analyzed using Analysis of Variance (ANOVA) at 95% confidence level (a 0,05).  The results obtained the highest daily growth in treatment B of 3.11 ± 0.04% per day, followed by treatment A of 2.58 ± 0.05% per day and the lowest in treatment C of 2.53 ± 0.03% per day.  The highest absolute growth was obtained in the frequency of feeding 3 times a day at 37.27 ± 0.20 g per individual, followed by 2 times a day at 27.64 ± 0.40 g per individual and the lowest at feeding 4 times a day at 26.51 ± 0.92 g per individual. Survival in all 3 treatments reached 100%.  Analysis of variance (α 0.05) shows that different feeding frequencies significantly affect the daily growth rate (0.05>0.00) and absolute growth (0.05>0.00) sangkuriang catfish larvae (C. gariepinus).

In this study, fish feed supplemented by probiotic, prebiotic and synbiotic were applied to enhance the immune response and survival rate of the fish against Streptococcus agalactiae infection. Treatments used in this study, were as follows: feed containing 1% (v/v) of probiotic (C), feed containing 2% (v/v) of prebiotic (D) and feed containing mixed of 1% (v/v) of probiotic + 2% (v/v) of prebiotic (E, defined as synbiotic). Control fish (both positive, A; and negative, B; treatments) were fed by fish feed without containing neither probiotic nor prebiotic. In this study, test fish used monosex (all male) red tilapia with the average of body weight of 13,43±2,97 gram. The fish were fed by supplemented feed within first 30 days pre injection. After that, the treated fish were challenged by 109 CFU/ml of S. agalactiae. Nile tilapia fed by synbiotic (treatment E) had higher immune response (haemoglobin, neutrofil, and phagocyte indices) than control, but were not significantly different than those of treatment C, and D. After challenged test by S. agalactiae, treatment C, D and E resulted significantly higher resistance than that of control. The survival rate of fish fed by supplemented feed containing probiotic (C), prebiotic (D) and synbiotic (E) were 76%, 76% and 80%, respectively; higher than than positive control (50%). The results showed that addition of probiotic, prebiotic and synbiotic in fish feed could increase immune response and survival rate against S. agalactiae.Keywords : tilapia, probiotic, prebiotic, synbiotic, Streptococcus agalactiae

Bakasang, produk fermentasi dari jeroan ikan, mengandung Bakteri Asam Laktat (BAL) yang beberapa diantaranya tergolong bakteri probiotik yang dapat meningkatkan pertumbuhan ikan. Penelitian ini bertujuan untuk mengkaji pengaruh pakan mengandung bakasang (PMB) terhadap pertumbuhan dan kelangsungan hidup ikan bawal (Colosoma macropomum) dan menentukan dosis paling efektif dari bakasang terhadap pertumbuhan dan kelangsungan hidup ikan bawal. Sebanyak 120 ekor ikan yang ditempatkan dalam 12 hapa dengan kepadatan 10 ekor ikan/hapa. Setelah proses aklimatisasi, ikan uji diberi PMB dengan empat dosis berbeda (A=0 ml/kg pakan, B= 50 ml/kg pakan, C=75 ml/kg pakan dan D=100 ml/kg pakan) dengan tiga ulangan pada masing-masing perlakuan, pada dosis 5%/bb/hari, diberikan dua kali sehari selama 14 hari. Hasil penelitian menunjukan bahwa pengaruh pemberian pakan meningkat bertambahnya konsentrasi dengan pertumbuhan terbaik teramati pada dosis 100 ml/kg pakan dengan bertumbuhan sebesar 8.7 gram. Hasil ini memperlihatkan bahwa bakasang merupakan sumber potential probiotik yang dapat meningkatkan pertumbuhan ikan bawal meskipun pengujian dengan periode pemeliharaan lebih lama perlu dilakukan untuk melihat pengaruh optimum dari PMB terhadap pertumbuhan dan kelangsungan hidup.    Bakasang, a fermentation product made from fish’s viscera, contains Lactic Acid Bacteria (LAB), some of which are probiotic bacteria that can increase fish growth. This study aimed to determine effect of fish feed containing bakasang (FCB) and the effective dose of bakasang on the growth of pomfret (Colosoma macropomum). 120 fish were placed in small net cage (1x1x1) m3. Following acclimatization process, the test fish were fed with four different doses of FCB (A = 0 ml/kg of feed, B = 50 ml/kg of feed, C = 75 ml/kg of feed and D = 100 ml/kg of feed) at a dose of 5% /w/day twice a day in triplicate for 14 days. The results showed that the effect of FCB on the pamfret fish growth increased in a dose dependent manner with best growth observed at a dose of 100 ml/kg of feed with growth of 8.7 gram, suggesting bakasang as potential source of probiotic that can increase the growth of pamfret fish although further study covering longer period time is required to measure the optimum potential of FCB on pamfret fish growth and survival rate.

Abstract Aquaculture has been known as one of solutions in dealing with food security problem through applying best practices of aquaculture and increasing fish production. In many countries, fish production is considered an essential activity contributing to household income and trade. However, fish feed has an expensive price, and it constitutes 60-70% total cost of production. The objective of this study is to reveal an alternative cheap source for additional ingredients to fish diet formulation of Tilapia larvae (Oreochromis niloticus). 240 fish larvae from local hatchery were used and cultured in 4 aquariums with different dose of protein diet (30%, 35%, 40%, and control). The source of protein diet is Polychaeta Nereis sp which was collected from surrounding Kastela Sea. Nereis sp was processed into dry meal and was added into the feed formulation. The result shows that the useful of 40% protein of Nereis sp gives the highest growth and survival rate of tilapia larvae, which is 44,99 g and 100%. It is followed by 35% and 30% Nereis protein, respectively. It is interesting that protein control which is feed commercial has almost similar growth level as the highest one. Specific growth rate (SGR) is 3,74%-3,79% per day for different protein dose of Polychaeta. Survival rate is 100% for all treatments which means all fish can survive and growth continuously from beginning to the end of the study.

This study presents results from a life cycle assessment (LCA) conducted following the CML-IA method on caged aquaculture of Nile tilapia (Oreochromis niloticus) species at Como River, Kenyir Lake, Terengganu, Malaysia. In this study, the greenhouse gas (GHG) estimation, calculated based on the Intergovernmental Panel on Climate Change (IPCC) 2006 Guidelines, showed that 245.27 C eq (1.69 Kg) of nitrate oxide (N2O) was emitted from the lake. The determination of LCA was conducted using several inputs, namely N2O, compositions of fish feed, materials used to build fish cages (infrastructure), main materials used during operation and several databases, namely Agri-footprint, Ecoinvent 3, European Reference Life-Cycle Database (ELCD), and Industry Data 2.0. The results show that feed formulation is the major contributor to potential environmental impact in aquaculture farming, at 55%, followed by infrastructure at 33% and operation at 12%. The feed formulation consisting of 53% broken rice contributed to marine ecotoxicity (MET), while those consisting of 44% fish meal and 33% soybean meal contributed to abiotic depletion (ABD) and global warming (GW), respectively. It is recommended that the percentage of ingredients used in feed formulation in fish farming are further studied to reduce its impacts to the environment.
