Abstract

Selenium is an essential micromineral that the body needs in modest amounts (0.2–12 mg/kg), yet it has important effects on the antioxidant defense, immune system, and digestive performance of aquatic species. This study aimed to analyze the growth of catfish (Clarias gariepinus) supplemented with feed additives containing selenium peptide through the coating method on feed. There were four different treatments, namely K (feed without feed additive), and feed with additive supplementation: A (3 g/kg feed), B (6 g/kg feed), and C (9 g/kg feed). A total of 15 catfish at an initial weight of 21.80 ± 0.29 g were reared in a 90×40×45 cm3 aquarium filled with water at a 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 of simple filtration in the container and water replacement to ensure optimum water quality values for catfish growth. The results showed that the final biomass of catfish fed with selenium peptide was significantly different (p<0.05) from catfish fed without selenium peptide, with a value of 1147,50 g and 96,67% of survival rate. Based on this study, the best dose of feed additive in catfish feed was 3 g/kg of feed. Keywords: Clarias gariepinus, growth, selenium peptide ABSTRAK Selenium adalah mikromineral esensial yang dibutuhkan tubuh dalam jumlah sedikit (0,2–12 mg/kg), akan tetapi sangat berperan dalam sistem anti-oksidatif, imunitas, dan kinerja pencernaan pada organisme akuatik. Penelitian ini bertujuan menganalisis pertumbuhan ikan lele (Clarias gariepinus) yang ditambahkan dengan feed additive mengandung selenium peptida melalui metode coating pada pakan. Terdapat empat perlakuan berbeda, yaitu K (pakan tanpa selenium peptida), dan pakan dengan suplementasi feed additive: A (3 g/kg pakan), B (6 g/kg pakan), dan C (9 g/kg pakan). Ikan lele ukuran 21,80 ± 0,29 g sebanyak 15 ekor dipelihara dalam akuarium berukuran 90×40×45 cm3 dengan total volume air 108 L, selama 45 hari. Ikan diberi pakan tiga kali sehari secara at satiation. Pengelolaan kualitas air dilakukan dengan filtrasi sederhana serta penggantian air untuk memastikan kualitas air optimal untuk pertumbuhan ikan lele. Hasil penelitian menunjukkan biomassa akhir ikan lele dengan suplementasi selenium peptida pada pakan berbeda nyata (p<0,05) dibandingkan dengan kontrol dengan nilai bobot sebesar 1147,50 g dan kelangsungan hidup 96,67%. Berdasarkan penelitian ini, dosis terbaik feed additive yang mengandung selenium peptida adalah 3 g/kg pakan pada ikan lele. Kata kunci: Clarias gariepinus, pertumbuhan, selenium peptida

Abstract

This study aimed to evaluate the growth performance and carbohydrate metabolism of Pacific whiteleg shrimp after feeding with different cinnamaldehyde concentrations and protein-energy ratios. The study used a completely randomized design with six treatments in triplicates. The treatments were S003213; treatment S053213; treatment S052814; treatment S102814; treatment S052815; and treatment S102815. The study was conducted for 56 days in a 76 L volume aquarium using shrimps with 1.38 ± 0.01 g at 200 individuals/m3. The results showed that the S053213 treatment was significantly different (P<0.05) compared to other treatments for the specific growth rate (SGR). Hexokinase (hk) and phosphoenolpyruvate carboxykinase (pepck) produced by the S053213 treatment were significantly different (P<0.05) from the S003213 treatment. The S052815 and S102815 treatments produced higher protein retention (PR) and protein efficiency ratio (PER) compared to other treatments (P<0.05) and also produced the same final average weight (FW) as the S003213 treatment. This research shows that vannamei fed by 0.10% supplementation dose of cinnamaldehyde with a decreased feed protein up to 28% and C/P ratio 14 and 15 are able to utilize feed as well as protein 32% without cinnamaldehyde. The addition of cinnamaldehyde with a higher C/P ratio requires a higher dose of cinnamaldehyde than the optimal dose. Keywords: Carbohydrate metabolism, cinnamaldehyde, growth, feed energy ratio, Pacific whiteleg shrimp ABSTRAK Penelitian ini bertujuan untuk mengevaluasi kinerja pertumbuhan dan metabolisme karbohidrat udang vaname Litopenaeus vannamei yang diberikan kadar sinamaldehid pada protein dan rasio energi pakan berbeda. Penelitian menggunakan rancangan acak lengkap (RAL) dengan enam perlakuan dan tiga ulangan. Adapun perlakuan terdiri dari perlakuan kontrol S003213; perlakuan S053213; perlakuan S052814; perlakuan S102814; perlakuan S052815; dan perlakuan S102815. Penelitian dilakukan selama 56 hari pemeliharaan pada akuarium volume 76 L menggunakan udang vaname berukuran 1,38 ± 0,01 g dengan kepadatan 200 individuals/m3. Hasil penelitian menunjukkan bahwa perlakuan S053213 berbeda nyata (P<0,05) dibandingkan perlakuan lainnya untuk parameter laju pertumbuhan spesifik (SGR). Parameter heksokinase (hk) dan phosphoenolpyruvate carboxykinase (pepck) yang tertinggi dihasilkan oleh perlakuan S053213 dan berbeda nyata (P<0,05) dengan perlakuan S003213. Pada perlakuan S052815 dan S102815 menghasilkan retensi protein (PR) dan rasio efisiensi protein (PER) lebih tinggi dibandingkan dengan perlakuan lainnya (P<0,05) serta menghasilkan bobot rata-rata akhir (FW) sama dengan perlakuan S003213. Penelitian ini menunjukkan bahwa udang vaname yang diberikan suplementasi sinamaldehid sebesar 0,10% dengan protein pakan 28% dan rasio C/P menjadi 14 dan 15 mampu pemanfaatan protein pakan yang sama dengan protein pakan 32% tanpa suplementasi sinamaldehid. Penambahan sinamaldehid dengan rasio C/P yang lebih tinggi membutuhkan dosis sinamaldehid yang lebih tinggi dari dosis optimal.

Abstract

This study aimed to assess the impact of charcoal inclusion in feed on the physiological responses and growth of catfish. The experiment employed a completely randomized design (CRD) with five treatments and four replicates. Charcoal doses in the feed were set at 0% (C0, control), 0.5% (C0.5), 1% (C1), 2% (C2), and 3% (C3). The catfish used weighed 3.95 ± 0.03 g and were kept in 20 hapa units (2×1×1 m³) with a stocking density of 70 fish/hapa for 60 days. The results indicated significant differences (p<0.05) in the hepatosomatic index between treatments, with the highest values recorded in C1 (2.15 ± 0.10b) and C0.5 (1.91 ± 0.19b). However, liver glycogen levels did not significantly vary across treatments (p>0.05). Charcoal supplementation enhanced blood mineral levels (calcium, phosphorus, manganese, and zinc) in the C2 and C3 groups. The highest blood glucose level was observed in C1 (p<0.05). Intestinal histological analysis showed that the highest villi height and surface area were recorded in the C2 group, with values of 540.0 ± 10.2 µm and 34.122 ± 1.311 µm², respectively. Additionally, 2% charcoal supplementation improved final weight, daily growth rate, and protein retention, while reducing feed consumption and the feed conversion ratio compared to the control. Overall, the inclusion of 2% charcoal positively influenced the intestinal histology of catfish, contributing to enhanced growth performance. The study also demonstrated that charcoal addition affected the hepatosomatic index, blood glucose, and blood mineral levels in catfish. Keywords: catfish, charcoal, growth, physiological response ABSTRAK Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian charcoal dalam pakan terhadap respons fisiologis dan pertumbuhan ikan lele. Penelitian dirancang dengan Rancangan Acak Lengkap (RAL) dengan lima perlakuan dan empat ulangan. Perlakuan dosis charcoal yang yang berbeda yaitu 0 (C0, kontrol), 0.5 (C0,5), 1 (C1), 2 (C2), dan 3% (C3). Ikan lele yang digunakan berbobot 3,95 ± 0,03 g/ekor dipelihara di hapa berukuran 2×1×1 m³ sebanyak 20 unit dengan kepadatan 70 ekor/hapa selama 60 hari. Hasil penelitian menunjukkan hepatosomatik indeks beda nyata antar perlakuan (p<0,05) nilai tertinggi terdapat pada perlakuan C1 2,15 ± 0,10b dan C0,5 1,91± 0,19b. Penambahan charcoal pada pakan tidak berbeda nyata terhadap glikogen hati (P>0,05). Penambahan charcoal dalam pakan dapat meningkatkan kandungan mineral darah ikan (kalsium, fosfor, mangan, dan zinc) pada perlakuan C2 dan C3. Nilai glukosa darah tertinggi pada pakan yang diberi pakan C1 (p<0,05). Hasil histologi usus menunjukkan nilai tertinggi pada tinggi vili dan luas permukaan vili usus terdapat pada perlakuan C2 (2% charcoal) dengan tinggi vili (540,0±10,2 µm) dan luas permukaan vili (34122 ± 1311 µm). Penambahan charcoal 2% pada pakan dapat meningkatkan bobot akhir, laju pertumbuhan harian, retensi protein, menurunkan konsumsi pakan dan feed convertion ratio dibandingkan kontrol. Pemberian charcoal 2% dalam pakan berpengaruh baik terhadap histologi usus ikan lele, sehingga dapat meningkatkan pertumbuhan pada perlakuan C2. Pada penelitian ini juga di temukan bahwa penambahan charcoal dalam pakan berpengaruh terhadap indeks hepatosomatik, glukosa darah, serta mineral darah ikan lele.

Abstract

This research evaluated the effect of taurine-enriched rotifers on the survival and growth of milkfish larvae. Twenty-five fertilized milkfish eggs were placed in a 250 L cylindrical fiber tank. This study used a completely randomized design with four treatments and five replications. Three days old larvae were given rotifers enriched with taurine at 0, 25, 50, or 75 mg/L. Larvae were cultured until they were 18 days old. The results showed that the taurine content in rotifers was higher in rotifer at 50 mg/L treatment, then decreased at the 75 mg/L treatment. Taurine content in the milkfish larvae aligned with taurine levels in rotifers. Furthermore, the taurine content in rotifers affected milkfish larvae' survival and body length. The highest larval survival and growth was obtained in the 50 mg/L taurine treatment. Thus, it can be concluded that taurine at 50 mg/L is the optimal rotifer enrichment dose for milkfish larvae. Keywords: growth, milkfish larvae, notochord, survival rate, taurine ABSTRAK Penelitian ini dilakukan untuk mengevaluasi pengaruh pemberian rotifera yang diperkaya taurin terhadap kelangsungan hidup dan pertumbuhan larva ikan bandeng. Dua puluh lima butir telur ikan bandeng yang telah dibuahi ditempatkan pada tangki fiber berbentuk silinder berukuran 250 L. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan lima ulangan. Larva berumur tiga hari setelah menetas diberi rotifer yang diperkaya taurin dengan dosis 0, 25, 50, atau 75 mg/L. Larva dipelihara hingga berumur 18 hari. Hasil penelitian menunjukkan bahwa kandungan taurin pada rotifer tertinggi diperoleh pada perlakuan rotifer 50 mg/L, kemudian menurun pada perlakuan rotifer 75 mg/L. Kandungan taurin pada larva ikan bandeng sebanding dengan kandungan taurin pada rotifer. Kandungan taurin pada rotifer berpengaruh nyata terhadap kelangsungan hidup dan panjang tubuh larva ikan bandeng. Kelangsungan hidup dan pertumbuhan larva tertinggi diperoleh pada perlakuan dosis 50 mg/L. Dari hasil penelitian dapat disimpulkan bahwa pemberian taurin 50 mg/L pada pengayaan rotifer merupakan dosis yang optimal untuk diberikan pada larva ikan bandeng.

Abstract

Cinnamon leaves contain active compounds such as polyphenols and flavonoids which have antioxidant properties and play a role in lipid metabolism processes. This active substance is known to reduce liver fat levels and has the potential to increase the immune response in catfish. This research aims to determine the effect of adding cinnamon leaf extract to feed on liver fat levels and the health of catfish. Cinnamon leaf extract was added to the feed at five different doses, namely 0 g/kg (control), 0.5 g/kg, 1 g/kg, 2 g/kg, and 4 g/kg feed. The results of the study showed that the addition of cinnamon leaf extract to the feed reduced the fat content in the liver of catfish as seen from the decrease in fat degeneration in the liver of catfish compared to the control. Total erythrocytes, hemoglobin levels and hematocrit levels of fish treated with the addition of cinnamon leaf extract to the feed were lower and significantly different (P<0.05) compared to controls, but total leukocytes were not significantly different between treatment and control.

Abstract

The objective of the study was to test dietary supplementation of yacon leaf on the carbohydrate utilization, growth performance, and glucose tolerance of striped catfish during the early-stage period. Fish were fed with five different levels of yacon leaf supplementation (0%, 0.5%, 1%, 1.5%, 2%) for nine weeks. Three hundred striped catfish (initial mean body weight: 14 ± 0.14 g) were maintained in 15 rectangular net cages. The results showed that the specific growth rate of fish with yacon leaf supplementation (3.46-3.79%) was higher than the control fish (3.19%) also the feed efficiency value. The highest protein retention was found on 1% yacon leaf fish diet, while the highest lipid retention was found on 1.5%. The blood glucose post-prandial was rise slower than the control fish. The glucose tolerance test also obtained less time to return to basal level after the glucose load. The increased of enzymatic were also present at the supplemented fish. The liver lipid and glycogen concentration was decreased, and the hepatic somatic index was increased. The blood biochemistry showed the lower level of total protein plasma and albumin in supplemented fish, and higher triglyceride and cholesterol levels due to the replenishment of energy storage in adipose tissues while fasting. Therefore, this study concludes that the yacon leaf dietary supplementation has the potential to improve carbohydrate utilization by promoting glucose use efficiently as the main energy, while protein can be utilized for growth. Our data suggest that the best level of yacon leaf supplementation in fish diets is 1.36%. Keywords: yacon-leaf, homeostatic, glucose, sparing-effect ABSTRAK Tujuan dari penelitian ini adalah untuk mengkaji efektifitas suplementasi daun insulin pada pakan terhadap pemanfaatan karbohidrat, kinerja pertumbuhan, dan toleransi glukosa pada benih ikan patin. Ikan diberi pakan dengan lima tingkat suplementasi daun insulin yang berbeda yaitu 0%, 0,5%, 1%, 1,5%, 2% selama sembilan minggu. Tiga ratus benih ikan patin (rata-rata biomasa awal: 14 ± 0,14 g) dipelihara dalam 15 keramba jaring berbentuk persegi panjang. Hasil penelitian menunjukkan bahwa laju pertumbuhan spesifik ikan yang diberi suplementasi daun insulin (3,46-3,79%) lebih tinggi dibandingkan ikan kontrol (3,19%) linier dengan nilai efisiensi pakan. Retensi protein tertinggi terdapat pada ikan dengan pakan daun insulin 1%, sedangkan retensi lemak tertinggi terdapat pada pakan 1,5%. Kenaikan glukosa darah post-prandial lebih lambat dibandingkan pada ikan kontrol. Kadar toleransi glukosa juga memperoleh waktu yang lebih singkat untuk kembali ke level basal setelah injeksi glukosa. Peningkatan aktivitas enzimatik juga terjadi pada ikan yang diberi suplementasi daun insulin. Konsentrasi lipid dan glikogen hati menurun, dan indeks somatik hati meningkat. Biokimia darah menunjukkan rendahnya kadar total protein plasma dan albumin pada ikan yang diberi suplementasi, serta kadar trigliserida dan kolesterol yang lebih tinggi selama proses pemulihan menggunakan cadangan energi dari jaringan adiposa saat dipuasakan. Oleh karena itu, penelitian ini menyimpulkan bahwa suplementasi daun insulin berpotensi untuk meningkatkan pemanfaatan karbohidrat dengan menstimulasi penggunaan glukosa secara efisien sebagai energi utama, sementara protein dapat dimanfaatkan untuk pertumbuhan. Data kami menunjukkan bahwa tingkat suplementasi daun insulin terbaik dalam pakan ikan adalah 1,36%. Kata kunci: daun insulin, efek hemat, homeostatis, glukosa

Abstract

upaya untuk mengurangi kadar lemak tersebut. Tujuan penelitian ini adalah mengevaluasi suplementasi L-karnitin dan tepung kayu manis terhadap kadar lemak dan tekstur daging ikan patin pada fase pembesaran. Ikan patin berukuran 125,4 ± 7,85 g dan panjang 24,71±0,68 cm dipelihara selama 60 hari dalam wadah hapa berukuran 2 x 1 x 1 m3. Ikan diberi pakan tiga kali sehari ad satiation dengan perlakuan, sebagai berikut: kontrol (K), penambahan L-karnitin 1 g kg-1 (LK 1), L-karnitin 2 g kg-1 (LK 2), kayu manis 5 g kg-1 (KM 5), dan kayu manis 10 g kg-1 (KM 10). Sampel diambil pada awal, pertengahan, dan akhir pemeliharaan untuk pengukuran kadar lemak daging. Parameter yang diamati yaitu lemak daging dan tekstur daging. Hasil menunjukkan bahwa pemberian KM 10 menghasilkan kadar lemak yang lebih rendah dari perlakuan lainnya setelah 30 hari dan penurunan yang lebih besar yaitu berkisar 51,06% dan 42,55% pada perlakuan LK 2 dan KM 10 pada hari ke-60. Nilai indeks hepatosomatik juga menurun yang diikuti oleh penurunan kadar lemak hati. Nilai kekerasan daging menunjukkan peningkatan kualitas yang terlihat dari nilai yang semakin rendah. Pemberian tepung kayu manis 10 g kg-1 pada fase pembesaran menunjukkan hasil terbaik pada pemberian selama 60 hari dalam menurunkan lemak daging ikan patin hingga memenuhi standar filet, karena adanya proses lipolisis serta pemanfaatan lemak menjadi energi. Kayu manis ini menjadi sangat potensial untuk dikembangkan sebagai feed additive dalam upaya memperbaiki kualitas daging ikan patin fase pembesaran.Striped catfish meat has a high-fat content which is undesirable to markets and customers alike and needs to be reduced. This study aims to evaluate the effect of dietary L-carnitine and cinnamon powder on reducing the fat content of striped catfish meat in the grow-out stage. Striped catfish measuring 125.4 ± 7.85 g and 24.71 ± 0.68 cm body length were kept for 60 days in a hapa with size 2 x 1 x 1 m3. Thefish were fed three times a day at satiation with the following treatments: control (K), the addition of L-carnitine 1 g kg-1 (LK 1), L-carnitine 2 g kg-1 (LK 2), cinnamon 5 g kg-1 (KM 5) and cinnamon 10 g kg-1 (KM 10). Sampling was conducted on the initial, middle and final day for meat fat content analysis. The parameters observed were meat fat and meat texture. The results showed that dietary KM 10 significantly reduced meat fat content compared to controls on the 30th and it showed a more significant reduction, namely 51.06% and 42.55%, in the treatment LK 2 and KM 10 after 60 days treatment. The hepatosomatic index value also decreased, followed by decreased liver fat levels. The lower values of meat hardness imply an increase in meat quality. It can be concluded that the application of dietary cinnamon powder at 10 g kg-1 (KM 10) is the best level to reduce the fat content of striped catfish meat in meeting the fillet standards. This cinnamon has excellent potential to be developed as a feed additive to improve the quality of striped catfish meat in the rearing phase.

Abstract

This experiment was conducted to evaluate the effect of phytase supplemented to the diet on phosphorus (P) digestibility and growth performance of the green catfish Hemibagrus nemurus. Five kinds of experimental diets were used in this experiment, namely diets A, B, C, D and E. Diet A, as a control, was supplemented with inorganic P, without phytase supplementation. Diet B, C, D and E were supplemented with 0, 20, 40 and 60 mg phytase/100 g soybean meal (SBM), respectively, without inorganic P supplementation. Fifteen fish with initial body weight of 6.9 + 0.2 g were stocked into each 60-l aquarium. Fish were fed on the diets for 60 days. Results indicated that P digestibility increased from 64.5% to 87.0% as phytase supplement increased from 0 mg in diet B to 60 mg phytase/100 g SBM in diet E. P digestibility in diet E was higher than that in diet A (77.6%). The daily growth rate and feed conversion ratio followed similar trend. P, Calcium (Ca) and Zinc (Zn) concentration in the whole body and bone of fish fed diet E were higher than the fish fed diet B, C and D, but were insignificant compared to the fish fed diet A. Nitrogen (N) and P loading by fish fed diet E were, respectively, 76% and 20% lower than those in fish fed the control diet. It is concluded that the inclusion of 60 mg phytase/100 g SBM in the diet of the green catfish could replace the utilization of inorganic P increase the digestibility of the diet thereby resulting in increased growth rate and reduced excretion of P and N into the waters. Keywords: Hemibagrus nemurus, phytase, soybean meal, phosphorus.

Abstract

ARTICLE HIGLIGHTS- Taurine improves eye development in golden rabbitfish larvae- Enhanced growth performance with taurine-enriched rotifers- Taurine positively impacts fish eye and body growthABSTRACTGolden rabbitfish (Siganus guttatus) is an emerging species for aquaculture industry, despite constrains faced on commercial scale of seed production due to the high mortality during the first-feeding stage. An experiment was conducted to determine the effect of taurine through enrichment of rotifers as live-feed on eye development and growth performance of larval golden rabbitfish. Observation of eye development was carried out by measuring eye diameter of the larva and development of the retina based on histology assessment. Growth performance was measured for absolute growth and fin development of the larvae and survival rate. The results showed that taurine-enriched rotifer generally provided better performances for eye development and growth of larval golden rabbitfish compared with control (without taurine). Increase of taurine dose up to 0.050 g/L resulted in an increase of eye diameter, absolute growth, fin development and survival rate. Further increased increment of the taurine tended to decrease the values of the measured parameters. The eye diameter of larval golden rabbitfish fed with 0.050 g/L taurine-enriched rotifer was significantly wider (106.1±9.8 µm) (P < 0.05) compared with control (58.2±14.3 µm), but did not significantly differ from other doses of taurine (P > 0.05). Body width of larvae fed with 0.050 g/L taurine-enriched rotifer was significantly higher (127.3±14.6 µm) (P < 0.05) compared with control (98.8±18.3 µm). In regard to eye development, growth performances (total length, fin development and survival rate), dose of taurine for rotifer enrichment fed to larval golden rabbitfish Siganus guttatus was 0.050 g/L.
