Abstract

Betaine plays some important roles in feed utilization and fish metabolism. The aim of this study was to evaluate the effect of dietary betaine supplementation on the growth performance and feed utilizationin hybrid grouper (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). A completely randomized experimental design with four dietary levels of betaine, i.e.0.0%, 0.5%, 1.0%, and 2.0% in quadruplicate was done.Hybrid grouper juvenile obtained from Brackishwater Aquaculture Development Center, Situbondo, with an initial body length and body weight of 5.89 ± 0.05 cm and 2.86 ± 0.09 g, respectively was used as the tested animal. The fish was maintained in 60 cm x 40 cm x 40 cm aquaria with 75 L working capacity with individual recirculating system with a fish density of 15 fish/aquarium for 50 days. Experimental diet was provided to apparent satiation twice a day. The results of this study demonstrated that dietary betaine at a level of 0.5% resulted in higher feed utilization efficiency, protein and methionine retentions, and growth performance and lower ammonia excretion than those of the control (P<0.05). Higher antioxidative status was indicated by the lower malondialdehyde (MDA) in the liver of fish fed with betaine supplemented diets at levels of 1 - 2%. In conclusion, betaine supplementation of 0.5% could increase feed utilization efficiency and growth performance of hybdrid grouper. Keywods: Betaine, Hybrid Grouper, Growth Performance, Feed, Antioxidative Status ABSTRAK Betain memegang beberapa peranan penting dalam pemanfaatan pakan dan metabolisme pada ikan. Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi betain pada pakan terhadap kinerja pertumbuhan dan pemanfaatan pakan pada juvenil ikan kerapu hybrid cantang (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan pakan dengan tingkat suplementasi betain yang berbeda, yaitu 0.0%, 0.5%, 1.0%, dan 2.0% dengan empat ulangan. Juvenil ikan kerapu cantang yang berasal dari Balai Pengembangan Budidaya Laut Situbondo dengan panjang dan bobot awal masing-masing 5.89 ± 0.05 cm and 2.86 ± 0.09 g digunakan sebagai hewan uji dalam penelitian ini. Ikan dipelihara dalam akuarium berukuran 60 cm x 40 cm x 40 cm dengan kapasitas 75L yang dilengkapi dengan sistem resirkulasi individu dengan kepadatan 15 ekor per akuarium selama 50 hari. Pakan uji diberikan hingga sekenyangnya dua kali sehari. Hasil penelitian ini menunjukkan bahwa suplementasi betain sebanyak 0.5% menghasilkan pemanfaatan pakan, retensi protein, retensi metionina, kinerja pertumbuhan dan ekskresi ammonia yang lebih baik daripada kontrol (P<0.05). Status antioksidasi yang lebih juga yang ditunjukkan dengan lebih rendahnya konsentrasi malondialdehid (MDA) pada hati ikan yang diberi pakan dengan suplementasi 1-2% betain. Berdasarkan hasil penelitian dapat disimpulkan bahwa suplementasi betain sebanyak 0.5% dapat meningkatkan efisiensi pemanfaatan pakan dan kinerja pertumbuhan ikan kerapu cantang.

Abstract

Phytoadditives have been acknowledged to have some beneficial effects on metabolic processes and health of some aquaculture species. This study aimed to evaluate the effect of dietary citral on carbohydrate utilization, growth and health performance of vannamei shrimp P. vannamei. This study used a completely randomized design (CRD) with four dietary treatments with different citral doses (0, 50, 75, and 100 mg citral/kg feed) in triplicates. Shrimp were reared for 60 days using fiber containers (50×50×80cm) of 30 shrimp/container. The frequency of feeding is given four times a day. Dietary citral supplementation of 100 mg/kg resulted in higher shrimp growth and feed utilization efficiency than those of the control. The level of amylase enzyme, post-prandial blood glucose, muscle, and liver glycogen were higher in the treatments with dietary citral than those of the controls. The shrimp immune response was also higher in the shrimp fed with dietary citral diets as shown by the higher total hemocyte count, respiratory burst, and phenoloxidase activity compared to those of the control. At the same time, antioxidant capacity in the hepatopancreas as indicated by superoxide dismutase and malondialdehyde level were also improved in shrimp with citral treatment. It can be concluded that dietary citral could increase the utilization carbohydrate, growth performance and health of shrimp at a concentration 75 mg/kg. Keywords: citral, carbohydrate, growth, health, P. vannamei ABSTRAK Secara umum telah diketahui bahwa fitoaditif memiliki pengaruh yang menguntungkan pada proses metabolisme dan kesehatan beberapa spesies akuakultur. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan citral pada pakan terhadap pemanfaatan karbohidrat, kinerja pertumbuhan dan kesehatan udang vanname. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dosis citral yang berbeda (0, 50, 75, dan 100 mg citral/kg pakan) dengan tiga ulangan. Udang vanname dipelihara selama 60 hari menggunakan wadah bak fiber (50×50×80cm) sebanyak 30ekor/wadah. Frekuensi pemberian pakan diberikan sebanyak empat kali sehari. Penambahan citral 100 mg/kg menghasilkan pertumbuhan udang yang lebih tinggi dan efisiensi pemanfaatan pakan dibandingkan kontrol. Tingkat enzim amilase, glukosa hemolim post-prandial, glikogen otot, dan glikogen hati lebih tinggi pada perlakuan penambahan citral dibandingkan kontrol. Respon imun udang juga lebih tinggi pada udang yang diberi penambahan citral seperti yang ditunjukkan oleh jumlah total hemosit, respiratory burst, dan aktivitas fenoloksidase yang lebih tinggi dibandingkan dengan kontrol. Pada saat yang sama, aktivitas antioksidan dalam hepatopankreas udang yang ditunjukkan oleh Superoksida dismutase dan Malondialdehida juga meningkat pada udang dengan perlakuan citral. Dapat disimpulkan bahwa penambahan citral dapat meningkatkan pemanfaatan karbohidrat, pertumbuhan dan kesehatan udang pada konsentrasi 75. Kata kunci: citral, karbohidrat, kesehatan, pertumbuhan, udang vaname

Abstract

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. Laju pertumbuhan ikan lele dengan tanpa penambahan nutrisi AB mix lebih tinggi dibandingkan perlakuan lainnya, sedangkan semua perlakuan dengan penambahan AB mix meningkatkan performa pertumbuhan tanaman kangkung dengan jumlah padat tebar ikan lele tidak berpengaruh pada pertumbuhan tanaman kangkung.

Abstract

Plankton plays an important role in shrimp cultivation in ponds, both as an indicator of water quality and as a natural food source for shrimp that are raised. The purpose of this study was to measure the relationship between the dynamics of the plankton community, the concentration of total organic matter, and water salinity with the abundance of plankton in intensive shrimp farming systems. The study was conducted on six units of ponds located in Cirebon district, West Java, Indonesia. The ponds were lined with HDPE on each side and plastic mulch at the bottom. Post larvae of shrimp were stocked at an average density of 110 shrimp.m-2 and maintained for 98 days. Water quality samples were collected for daily measurement. Data were analyzed descriptively and then analyzed using Pearson's correlation test and regression. The results of this study showed that during the shrimp rearing period, 65 species of plankton were identified, consisting of Chlorophyta 20%, Cyanophyta 15.38%, Diatoms 26.15%, Euglenophyta 6.15%, Dinoflagellates 4.62%, Protozoa 10.77%, and Ciliates 16.92% with an average density ranging from 7.56x105-19.99x105 cells.mL-1. Chlorella sp. (Chlorophyta) and Oscillatoria sp. (Cyanophyta) were found to be the dominating species in all ponds. Total phytoplankton density tended to be higher during the first 54 days of culture. The results of the correlation and regression tests showed that the composition of plankton, the concentration of total organic matter, and the salinity of the water affected the abundance of plankton in the pond.

Abstract

Pacific white shrimp Litopenaeus vannamei aquaculture has become a primary alternative to increase national aquaculture production following the decline in tiger shrimp farming due to disease outbreaks. However, the grow-out phase still faces challenges such as limited availability of high-quality post-larvae and deteriorating environmental conditions. The application of probiotics is considered a promising approach, as it can improve water quality, suppress pathogens, and enhance shrimp growth and resilience. This study integrates probiotic application into the grow-out management system to improve production efficiency and sustainability. The research was conducted through direct observation and active participation in farming activities, combined with secondary data collection from verified sources. Observed parameters included mean body weight (MBW), average daily growth (ADG), and survival rate (SR). The grow-out activities involved pond preparation, stocking of post-larvae at a density of 120–180 individuals/m² following acclimatization, blind feeding during the first 10 days, and feed administration based on the feeding rate (FR) thereafter. Daily water quality management and disease control were also carried out. The cultivation period lasted for three months, followed by partial and total harvesting, yielding up to 3 tons of shrimp per pond. Post-harvest, the shrimp were sorted and distributed to consumers using refrigerated vehicles.
