Abstract

ABSTRACT This research was performed to evaluate growth performance and meat quality at different feeding period of striped catfish Pangasianodon hypopthalmus fed on cinnamon leaves Cinnamomum burmanni enriched diet. Twenty fishes at the average body weight of 21.24±2.39 g were distributed  into 100×40×50 cm3 of aquarium. Fish were fed on the diet contained C. burmanni leaves of either 0.0%, 0.5%, 1.0%, or 1.5% respectively for 60 days. Fish were fed on those diets three times a day at satiation. Fish meat quality was evaluated by organoleptic test and proximate analysis at day-20, 40, and  60. The result showed that until day-40, fish fed on the diet contained 0.0%, 0.5%, and 1.0% cinnamon leaves had no significant difference on growth, hence still showed higher growth than fish fed at the dose of 1,5%. Meanwhile at day-60, fish fed on the diets contained either 0.5%, 1.0%, and 1.5% cinnamon leaves significantly had lower growth than that fed on 0.0% cinnamon leaves. In accordance to the growth response, diet contained 0.5% cinnamon leaves given for 40 days has shown the best texture and the highest protein content of fish meat.               Keywords: cinnamon leaves, striped catfish, growth, meat texture  ABSTRAK Penelitian ini dilakukan untuk mengevaluasi pertumbuhan dan kualitas daging ikan patin Pangasianodon hypopthalmus yang diberi pakan mengandung tepung daun kayu manis Cinnamomum burmanni dengan dosis berbeda.

Abstract

ABSTRACT This experiment was conducted to improve the quality of rubber seed meal fermented using sheep rumen liquor based diet (RSMF) with amino acid supplementation for Nile tilapia Oreochromis niloticus. This experiment consisted of five treatments with three replications. The treatments were 0% protein from RSMF as control; 50% RSMF; 50% RSMF with lysine; 75% RSMF and 75% RSMF with lysine. Tilapia with an initial body weight of 6.29±0.12 g were reared for 40 days and the fish were fed three times daily at satiation level (8.00 am, 12.00 pm and 16.00 pm). The data were statistically analysed by using one-way analysis of variance (ANOVA) using software SPSS version 16.0 at 95% (p<0.05) confidence interval and Tukey test for the post hoc test. The results showed that the addition of lysine in the 75% RSMF diets could increased final weight, but did not significantly different to protein efficiency ratio (PER), decreased feed convertion ratio (FCR) and biochemical body composition. The data indicated that quality of 75% RSMF could improved after lysine supplementation, but still lower than using 50% RSMF and soybean meal as protein source. Keywords: amino acid supplementation, Oreochromis niloticus, rubber seed meal ABSTRAK Penelitian ini dilakukan untuk meningkatkan kualitas pakan dengan tepung bungkil biji karet yang difermentasi dengan cairan rumen domba (TBBKF) melalui suplementasi asam amino untuk ikan nila Oreochromis niloticus.

Abstract

ABSTRACT In this study, tambaqui Colossoma macropomum juvenile were given feed supplemented with clove oil Syzygium aromaticum at a dose of 0 and 100 mg/100 g diet. This study purposed to assessment the effect of clove oil supplementation at high dose (100 mg/100 g diet) on growth performance and health status of freshwater tambaqui. As many as 25 fishes with initial body weight 7.62±0.44 g maintained in 15 aquariums for 45 days. Each treatment consisted of three replications. Data were analyzed by t-test. The results showed that tambaqui growth performance on both treatments were not significantly different. However, supplementation of high doses 100 mg clove oil/100 g diet showed reduce on the blood parameters and declining the abundant of intestinal microflora in tambaqui gut, but the types seen more diverse. The observation of fish liver histology showed that hepatocyte cells in the treatment of 100 mg clove oil become smaller and dense compared with 0 mg clove oil treatment. The use of high doses of clove oil does not interfere with the tambaqui growth performance despite the downturn in the physiological responses were observed. Keywords: clove oil, Syzygium aromaticum, Colossoma macropomum, growth performance  ABSTRAK Di dalam penelitian ini, benih ikan bawal tawar Colossoma macropomum dipelihara dengan pemberian pakan yang ditambah minyak cengkeh Syzygium aromaticum pada kadar 0 dan 100 mg/100 g pakan.

Abstract

ABSTRACT  This study was aimed to perform depuration of Pb contained in tilapia body. The experiments were conducted in aquarium using compost of Gliricidia sepium leaf at a concentration of 10g/L, 20 g/L, 30 g/L, 40 g/L, and 0 g/L (control). The result showed that Pb level in fish muscle immersed with compost of Gliricidia leaf at a dose of 30 g/L for five days successfully decreased to a safe limit for human consumption (<0.3 mg/kg). However, decrease of Pb level in fish liver and kidney to finally reach the safe limit required seven days. Decreasing level of lead in the organs of experimental fish along with the increasing level of Pb in compost and maintenance media indicated that Pb accumulated in fish were released into the maintenance media by compost through chelation process. To conclude, compost of G. sepium leaves can be used as the material for depuration of Pb in the body of tilapia Keywords: humic acid, fulvic acid, depuration, Gliricidia leaves, lead, red tilapia  ABSTRAK  Penelitian ini bertujuan untuk mendepurasi Pb yang terkandung di tubuh ikan nila. Percobaan dilakukan di dalam akuarium menggunakan kompos daun gamal pada konsentrasi 10 g/L, 20 g/L, 30 g/L, 40 g/L, dan 0 g/L (kontrol). Hasil penelitian menunjukkan bahwa, Pb di daging ikan yang direndam dengan kompos daun gamal pada konsentrasi 30 g/L selama lima hari, kadarnya menurun hingga batas aman untuk dikonsumsi manusia (<0,3 mg/ kg). Penurunan Pb di hati dan ginjal untuk mencapai kadar aman membutuhkan waktu yang lebih lama, yakni tujuh hari. Seiring dengan menurunnya kadar Pb dalam organ ikan uji, kisaran Pb dalam kompos dan media budidaya meningkat, menunjukkan bahwa Pb dari tubuh ikan dilepaskan ke media budidaya dan terjadi proses khelat oleh kompos. Dengan demikian, kompos daun gamal bisa digunakan sebagai bahan pendepurasi Pb dari tubuh ikan nila. Kata kunci: asam humat, asam fulvik, depurasi, daun gamal, timbal, nila merah

Abstract

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.
