ABSTRACTThis study was conducted to evaluate stress responses of transportation on red tilapia Oreochromis sp. which given feed containing chromium. Three isonitrogenous and isocaloric experimental feeds were prepared, these diets were control (without chromium), CrPic 1 mg/kg, and CrYst 2 mg/kg supplementation in feed, all group were arranged triplicate. Satiation feeding was done three times a day. After a 60-day feeding experiment, the experimental fishes were fasted and distributed in polyethylene bags (N=60 fish/bag) containing 3 L of water, subjected to condition of transport simulation for 13 hours. Survival rate, levels of plasma cortisol, blood glucose, superoxide dismutase (SOD), and malondialdehyde (MDA) enzyme were observed at before transportation, after transportation, one day, and two days after transportation. The result showed that chromium supplementation reduced the levels of plasma cortisol before and after transportation, one day, and two days after transportation. Also, it decreased blood glucose compared with control significantly before transportation and one day after transportation. The SOD enzyme concentration increased significantly after fish was fed with feed containing chromium for 30 days, while the MDA enzyme concentration increased significantly after two days of transportation. However, there was no significant difference in the survival of red tilapia between treatments. The best result was obtained in the treatment of fish which fed with feed containing chromium. CrPic supplementation 1 mg/kg and CrYst 2 mg/kg increased the body resistance in red tilapia by decreasing the negative effect of stress while transportation. Keywords: stress, transportation, red tilapia, chromium ABSTRAKPenelitian dilakukan untuk mengevaluasi respons stres transportasi ikan nila merah Oreochromis sp. yang diberikan pakan yang mengandung kromium. Pada penelitian ini digunakan tiga jenis pakan, terdiri atas pakan tanpa suplementasi kromium (kontrol), pakan bersuplementasi kromium pikolinat (CrPic 1 mg/kg), dan kromium yeast (CrYst 2 mg/kg), semua perlakuan diulang sebanyak tiga ulangan. Pemberian pakan sebanyak tiga kali sehari dan dilakukan secara at satiation. Setelah 30 hari pemeliharaan, ikan uji dipuasakan dan didistribusikan dalam plastik polietilen (N=60 ekor ikan/kantong plastik) yang berisi 3 L air, dilakukan dengan simulasi transportasi selama 13 jam. Parameter yang diamati pada penelitian ini adalah kelangsungan hidup, kortisol, glukosa darah, enzim superoksida dismustase (SOD), dan malondialdehida (MDA) saat sebelum transportasi, sesaat setelah transportasi, sehari, dan dua hari setelah transportasi. Hasil yang didapatkan adalah suplementasi kromium menurunkan konsentrasi kortisol secara signifikan sebelum transportasi, sesaat, sehari, dan dua hari setelah transportasi. Suplementasi kromium menurunkan glukosa darah secara signifikan pada saat sebelum transportasi dan sehari setelah transportasi. Konsentrasi enzim SOD meningkat secara signifikan setelah pemberian pakan bersuplementasi kromium selama 30 hari, sedangkan konsentrasi enzim MDA meningkat secara signifikan setelah dua hari transportasi pada ikan yang diberi pakan bersuplementasi kromium. Namun, tidak ada perbedaan yang signifikan pada kelangsungan hidup ikan nila merah antarperlakuan. Hasil terbaik diperoleh pada perlakuan ikan dengan suplementasi kromium. Suplementasi 1 mg/kg CrPic dan 2 mg/kg CrYst dapat meningkatkan daya tahan tubuh pada budidaya ikan nila merah dengan menurunkan pengaruh negatif stres akibat transportasi.

ABSTRACTThis study aimed to evaluate the growth performance and resistance to salinity stress of striped catfish juvenile reared in biofloc with different feeding rate (FR). The treatments applied in this study were rearing the fish in biofloc with FR 5% and 8% of biomass per day, and rearing the fish with a FR of 8% per day without biofloc system as the control. The fish with an initial average length of 1.81 ± 0.20 cm were stocked in 9 units of 50 L aquaria with density of 40 ind/aquaria (800 ind/m3) for 15 days rearing period. In biofloc systems, the addition of tapioca as a source of organic carbon was done every day with an estimated C/N ratio of 10. No water exchange was done in biofloc systems, whereas regular water exchange was applied in the control. Results of the experiment showed that survival was not significantly different amongst treatments (P>0.05). However, the specific growth rate of the fish in biofloc system with a FR of 8% per day showed the highest value and was significantly different from other treatments (P<0.05). Fish reared in biofloc system tend to have lower feed conversion ratios (FCRs) than the control. The lowest FCR was found in fish reared in biofloc system with 5% FR and significantly lower than control (P<0.05). Salinity stress test was conducted by soaking 15 juveniles in water with a salinity of 20 g/L for an hour. The survival of fish after salinity stress test were significantly higher for fish reared in bifloc system than control (P<0.05). These data showed that rearing striped catfish juvenile in biofloc system could reduce FCR, increase the growth, and robustness of fish. Keywords: biofloc, feeding rate, growth, salinity stress test, striped catfish ABSTRAKPenelitian ini bertujuan untuk mengevaluasi kinerja pertumbuhan dan ketahanan benih ikan patin terhadap stres salinitas yang dipelihara dalam sistem bioflok dengan tingkat pemberian pakan (FR) berbeda. Perlakuan yang terdapat dalam penelitian ini adalah benih patin yang dipelihara dalam sistem bioflok dengan FR 5% dan 8% per hari, dan pemeliharaan benih dengan FR 8% per hari tanpa penambahan sumber karbon sebagai kontrol. Benih patin dengan panjang rata-rata awal 1,81 ± 0,20 cm dipelihara dalam 9 unit akuarium dengan volume air 50 L dan kepadatan 40 ekor/akuarium (800 ekor/m3) selama 15 hari. Pada sistem bioflok, penambahan tapioka sebagai sumber karbon dilakukan setiap hari dengan C/N 10. Pada sistem bioflok tidak dilakukan pergantian air, sedangkan pada kontrol dilakukan pergantian air. Kelangsungan hidup ikan tidak berbeda nyata antar perlakuan. Namun, tingkat pertumbuhan spesifik ikan dalam sistem bioflok dengan FR 8% per hari menunjukkan nilai tertinggi dan berbeda nyata antar perlakuan (P<0,05). Benih yang dipelihara pada sistem bioflok memiliki rasio konversi pakan (FCR) yang lebih rendah dibandingkan kontrol, namun tidak terdapat perbedaan yang signifikan antara perlakuan bioflok (P>0,05). Uji stres salinitas dilakukan dengan merendam 15 ekor benih patin pada air dengan salinitas 20 g/L selama satu jam. Kelangsungan hidup setelah uji stres salinitas dari benih yang dipelihara di bioflok secara signifikan lebih tinggi dibandingkan kontrol (P<0,05). Hasil penelitian menunjukkan bahwa pemeliharaan benih patin pada sistem bioflok dapat menurunkan FCR, dan meningkatkan pertumbuhan dan ketahanan ikan terhadap stres salinitas.

ABSTRACTThis study was conducted to evaluate the digestibility of biofloc meal collected from catfish culture as a feed raw material for Pacific white shrimp Litopenaeus vannamei diet. A basal feed with 43% crude protein content was used as a control diet and mixed with 2% of binders and 0.5 % of Cr2O3 as a marker for digestibility. The experimental diets were made by mixing 67.5% of the basal diet with 30% of biofloc meal, 2% of binders and 0.5 % of Cr2O3. Nine units of glass tanks (90 cm ×40 cm× 35 cm) filled with 100 L seawater were used as the experimental culture units. White shrimp with an average body weight of 5.61 ± 0.09 g was randomly distributed to each experimental tank at a density of 20 shrimp/tank. The feed was offered at a level of 5% shrimp biomass per day at a frequency of four times a day. The results showed that the dry matter digestibility of feed with 30% biofloc meal in shrimp were similar to that of the reference diet. However, protein and fat digestibility of feed containing biofloc meal were considerably higher than those of the reference diet. Feeding shrimp with 30% biofloc meal diet resulted in higher survival and specific growth rate and lower feed conversion ratio than those of the control. The digestibility of bioflocs dry matter, protein and lipid in Pacific white shrimp obtained in this study were 54.9%, 76.3% and 79.3%, respectively.Keywords: biofloc, digestibility, catfish, shrimp ABSTRAKPenelitian ini dilakukan untuk mengevaluasi kecernaan tepung bioflok yang diambil dari media pemeliharaan ikan lele sebagai bahan pakan udang vaname Litopenaeus vannamei.

ABSTRACT Carotenoids were known as pigment sources, the precursor of vitamin A, potential antioxidant and can improve the health status of fish. Furthermore, there are also studies that reveal the role of carotenoids in bone formation and metabolism. This study was conducted to determine the effect of different carotenoids at two different doses in the feed on growth, pigmentation, vitamin A conversion, blood profile, antioxidant activity, and calcium bone of the rainbow fish. Twenty-one aquariums with a volume of 20 L each stocked with 20 fish (1.08 ± 0.03 g of body weight and 4.56 ± 0.07 cm of body length). The experiment applied seven experimental diets (in triplicates) consisted of three types of carotenoids were astaxanthin (AS), canthaxanthin (CS), and lutein (LS) and two doses (130 and 260 mg/kg), i.e. AS-130, AS-260, CS-130, CS-260, LS-130, LS-260 and basal (without carotenoids) as the control. The fish were fed for 56 days of experimental period. The results showed that carotenoid diets were able to increase growth, total carotenoids, percentages of chromatophores, vitamin A conversion, erythrocyte, leukocytes, packed cell volume (PCV), neutrophils, and hemoglobin (Hb) compared to the control. Fish fed dietary astaxanthin at a level of 260 mg/kg was superior compared to other diets. Dietary carotenoids were also capable of decreasing the endogenous antioxidant activity of superoxide dismutase (SOD) and malonyl dialdehyde (MDA) and increased the calcium level in fish bone than basal diet. Keywords: carotenoids, growth, health status, Melanotaenia parva, pigmentation ABSTRAK Karotenoid diketahui sebagai sumber pigmen, prekursor vitamin A, antioksidan potensial dan dapat meningkatkan status kesehatan ikan. Selain itu, karotenoid juga memiliki peran dalam formasi dan metabolism tulang. Penelitian ini dilakukan untuk mengevaluasi pengaruh jenis dan dosis karotenoid yang berbeda terhadap pertumbuhan, pigmentasi, konversi vitamin A, gambaran darah, aktifitas antioksidan dan kalsium tulang ikan rainbow Kurumoi. Sebanyak 20 ekor ikan (bobot tubuh rata-rata 1,08 ± 0,03 g dan panjang total rata-rata 4,56 ± 0,07 cm) dan diberi makan pakan yang mengandung karotenoid. Pakan uji terdiri atas tiga jenis karotenoid dengan tiga ulangan yaitu astaksantin (AS), cantaksantin (CS), dan lutein (LS) dan dua dosis (130 dan 260 mg/kg) dikodekan dengan AS-130, AS-260, CS-130, CS-260, LS-130, LS-260 dan basal (tanpa karotenoid) sebagai kontrol. Ikan diberi makan selama 56 hari pemeliharaan. Hasil penelitian menunjukkan bahwa karotenoid dapat meningkatkan pertumbuhan, total karotenoid, persentase kromatofora, konversi vitamin A, eritrosit, leukosit, hematokrit, neutrofil, dan hemoglobin dibandingkan dengan kontrol. Ikan yang diberi pakan mengandung astaksantin 200 mg/kg lebih baik dibandingkan denga pakan uji lainnya. Pakan yang mengandung karotenoid juga mampu menurunkan antioksidan endogenus superoxide dismutase (SOD) dan malonyl dialdehyde (MDA), serta meningkatkan kalsium tulang ikan dibandingkan pakan kontrol.

ABSTRACTThe study proposed to discover the optimum protein content and energy-protein ratio in practical diet for snakehead, Channa striata. The experiment applied complete randomized design, consisted of six treatments with four replications on each treatment. The treatments were: A (32.5%; 11.82 kcal GE/g), B (32.5%; 13.32 kcal GE/g), C (37.17%; 10.64 kcal GE/g), D (37.33%; 12.07 kcal GE/g), E (43.08%; 10.02 kcal GE/g), and F (42.88%; 10.66 kcal GE/g). Snakehead with average weight of 6.21 ± 0.03 g were reared for 8 weeks. The treatments showed significant results. Increased protein dietary level had increased the growth rate and treatment with high energy-protein ratio at the same protein dietary level provided better growth performance. However, increased energy-protein ratio at E and F treatments caused a decline in growth performance. The improvement of energy-protein dietary ratio had positive correlation with the level of lipid and protein content in fish body. Similar finding was found in liver and muscle glycogen. The results also showed that the increament of energy-protein dietary ratio was significantly and positively correlated with cholesterol, triglyceride, HDL, glucose, and albumin, yet it had no significant effect on LDL. It can be concluded that excellent growth performance was achieved by protein dietary level of 37.33% and energy-protein ratio of 12.07 kcal GE/g.Keywords: energy-protein ratio, growth, snakehead ABSTRAKPenelitian ini bertujuan untuk memperoleh kadar protein dan rasio energi-protein pakan buatan yang optimum bagi performa pertumbuhan ikan gabus.

Bobot rata-rata ikan gabus yang digunakan dalam penelitian ini yaitu 6,21 ± 0,03 g dan dipelihara selama 8 minggu. Hasil penelitian menunjukkan bahwa peningkatan kadar protein pakan meningkatkan laju pertumbuhan, dan perlakuan dengan rasio energi-protein tinggi pada level protein pakan yang sama memberikan kinerja pertumbuhan yang lebih baik. Namun demikian, pada perlakuan E dan F, peningkatan rasio energi-protein menyebabkan penurunan kinerja pertumbuhan. Peningkatan rasio energi-protein pakan berkorelasi positif terhadap kadar lemak dan protein tubuh ikan. Hal yang sama juga terjadi pada glikogen hati dan otot. Hasil penelitian juga menunjukkan bahwa peningkatan rasio energi-protein pakan berpengaruh nyata (P<0,05) dan berkorelasi positif terhadap kolesterol, trigliserida, HDL, dan albumin, tetapi tidak berpengaruh nyata terhadap LDL (P>0.05). Kesimpulan yang didapat adalah kinerja pertumbuhan optimal dihasilkan oleh kadar protein pakan 37,33% dan rasio energi protein pakan 12,07 kkal GE/g.Kata kunci: albumin, energi, ikan gabus, pertumbuhan, protein

ABSTRACT Ornamental fish is non consumption fish which is an important source of Indonesian foreign exchange. The objective of this study is to analyze the productivity of bronze corydoras Corydoras aeneus ornamental fish through increased stocking density with biofloc technology. The average weight of the experimental corydoras was 0.61 ‒0.72 g with 2.32‒2.40 cm standard length. This study used a randomized design method with biofloc technology treatment in 3000, 4500, and 6000 fish/m2 stocking densities. The results showed that the daily length and weight-growth rate among treatments were not significantly different (P>0.05), while survival rate and the number of fish production on all treatments were significantly different (P<0.05). The water quality during the rearing period, such as temperature, pH, alkalinity, ammonia, nitrite, and nitrate, were in a tolerable range for corydoras culture. The total suspended solids tended to be higher due to higher stocking density. The best productivity using biofloc technology obtained from 6000 fish/m2 stocking density. Keywords: Biofloc technology, Corydoras aeneus, growth rate, stocking density, survival rate.

The objective of this study was to determine the optimum dose of melastoma Melastoma malabathricum leaf extract that can inhibit the gonad development of Nile tilapia and increase its growth rate. This study used a completely randomized design containing five extract dose treatments (0, 0.5, 1, 2, and 4 g/kg diet doses) and three replications. The undifferentiated Nile tilapia larvae (7 days post hatching) were randomly distributed (n=30) to fifteen aquaria (100×50×50 cm3) and maintained for 112 days using a common recirculation system. The results showed that all dose treatments were not significantly different (P>0.05) in gonadosomatic index values of the D84 and D98 samplings. However, the 1 g/kg diet (D112) was significantly different (P<0.05) in all dose treatments. The final histological results (D112) showed that the 1 g/kg diet obtained the highest inhibition level of the testis and ovary developments, which were still in stage II compared to 0.5 g/kg diet (stage III) and control (stage IV and V). The highest average weight, absolute growth rate, and specific growth rate were obtained in the 1 g/kg diet dose which was significantly different (P<0.05) compared to the control. The percentage of males increased significantly (P<0.05) following the increased dose treatment fed to the fish (4 g/kg diet) with 80.12±4.67%, but the survival rate significantly decreased (P<0.05) compared to the control. The administration of 1 g/kg diet dose obtained the best dose and potential as an inhibiting agent for gonad development in Nile tilapia.

Penelitian ini menggunakan rancangan acak lengkap yang terdiri atas lima perlakuan (dosis 0; 0,5; 1,0; 2,0; dan 4,0 g/kg pakan) dan tiga ulangan. Larva ikan nila sebelum kelamin terdiferensiasi (7 hari pascatetas) secara acak (n=30) dimasukkan ke dalam 15 buah akuarium (100×50×50 cm3) dan dipelihara selama 112 hari pada sistem resirkulasi. Hasil menunjukkan bahwa semua perlakuan tidak berbeda nyata (P>0,05) terhadap nilai GSI pada sampling D84 dan D98. Namun, perlakuan 1 g/kg pakan pada sampling D112 berbeda nyata (P<0,05) dengan semua perlakuan. Hasil histologi terakhir (D112) menunjukkan bahwa perlakuan 1 g/kg pakan mengindikasikan penghambatan perkembangan testis dan ovari yang paling besar yang masing-masing berada pada TKG II, dibandingkan dengan perlakuan 0,5 g/kg pakan (TKG III), dan dibandingkan dengan kontrol (TKG IV dan TKG V). Pengamatan terhadap bobot rata-rata, laju pertumbuhan mutlak, dan laju pertumbuhan harian tertinggi diperoleh pada perlakuan 1 g/kg pakan yang berbeda nyata (P<0,05) dibandingkan dengan kontrol. Persentase jantan meningkat secara signifikan (P<0,05) seiring meningkatnya konsentrasi ekstrak yang mencapai 80,12±4,67% pada perlakuan 4 g/kg pakan, namun tingkat kelangsungan hidup menurun secara signifikan (P<0,05) dibandingkan dengan kontrol. Pada keseluruhan parameter, pemberian ekstrak 1 g/kg pakan merupakan dosis terbaik dan potensial sebagai agen penghambat perkembangan gonad pada ikan nila.

ABSTRACT The objective of this research was to determine the optimum level of organic selenium supplementation in improving the growth performance of Nile tilapia Oreochromis niloticus fed with diet containing low protein level. Basal diet was formulated to contain 28% protein with three different levels of organic selenium supplementation, namely 0 (control), 3, and 6 mg Se/kg feed. Furthermore, to evaluate selenium function on protein utilization and sparring effect, a diet with 30% of protein content was also used as a comparison. In this regard, this study was conducted using a completely randomized experimental design with four treatments and three replications. Nile tilapia with an average body weight of 8.05 ± 0.25 g were reared in the 100×50×50 cm3 aquarium at a density of 15 fish/aquarium. The experimental fish were reared for 60 days and fed three times daily to apparent satiation levels. Dietary supplementation of organic Se resulted in higher fish biomass, lower feed conversion ratio, higher protein retention and daily growth rate compared to the control diets with 28% and 30% protein levels. In conclusion, dietary supplementation of organic Se at 3 mg organic Se/kg feed could significantly increase protein utilization and improve the growth performance of Nile tilapia. Keywords: tilapia, protein sparing effect, organic selenium, feed ABSTRAK Tujuan dari penelitian ini adalah menentukan tingkat suplementasi selenium organic pada pakan untuk meningkatkan kinerja pertumbuhan ikan nila Oreochromis niloticus. Pakan basal diformulasikan mengandung 28% protein dengan tiga tingkat selenium organik yaitu 0 (kontrol), 3, dan 6 mg Se/kg pakan. Selanjutnya untuk mengevaluasi penggunaan selenium pada pemanfaatan protein dan efek sparring, pakan dengan 30% protein juga ditambahkan sebagai perlakuan pembanding. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan tiga ulangan. Ikan nila dengan bobot rata-rata adalah 8.05 ± 0.25 g dipelihara dalam akuarium 100 × 50 × 50 cm3 dengan kepadatan 15 ikan/akuarium. Ikan dipelihara selama 60 hari dan diberi pakan tiga kali sehari secara at satiation. Pemberian pakan dengan suplementasi Se organic menghasilkan biomassa ikan yang lebih tinggi, rasio konversi pakan yang lebih rendah, retensi protein dan laju pertumbuhan harian yang lebih tinggi daripada perlakuan control dengan kadar protein 28% dan 30%. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa suplemtasi pakan ikan nila dengan 3 mg Se organik/kg pakan dapat meningkatkan pemanfaatan protein pakan dan kinerja pertumbuhan ikan Nila. Kata kunci: ikan nila, protein sparing effect, selenium organik, pakan.
