Abstract

Nutritional quality of lupin based shrimp (Penaeus monodon) aquaculture feeds was evaluated in terms of pellet water stability. Two series of water stability experiments were carried out to study the effects of lupin meal inclusions as an dietary protein alternative for fish meal (Experiment 1) and soybean meal (Experiment 2) on percentage dry matter and protein leachings of the compounded test diets.  Increasing the replacement levels of dietary fish meal with lupin meal resulted in significant decrease (P<0.05) of pellet water stability over the 480-minute immersion period. A significant improvement in water stability with the increase of the soybean meal replacement levels with lupin meal up to 50% was found, however, further increase above 50% substitution level resulted in reduced water stability of the diets. It is  concluded that lupin meal can not totally replace either fish meal or soybean meal in shrimp formulated diets and a 50% replacement level of dietary fish meal or dietary soybean meal with lupin gives a promising good result in terms of pellet water stability for P. monodon diets.

Abstract

Pakan merupakan salah satu faktor penting yang berpengaruh terhadap pertumbuhan ikan patin (Pangasius hypophtalmus).  Kandungan protein dalam pakan merupakan sumber energi utama yang berperan juga sebagai komponen struktural penyusun sel dan jaringan tubuh.  Karena itu, protein pakan mempunyai peran penting pada proses pertumbuhan ikan patin.  Pada proses pencernaan diperlukan enzim untuk menghidrolisis ikatan peptida menjadi asam amino.  Proses ini dapat ditingkatkan dengan menggunakan enzim bromelin dalam pakan pada benih ikan patin.  Tujuan dari penelitian ini adalah untuk mengkaji pengaruh enzim bromelin dalam pakan terhadap efisiensi pemanfaatan pakan dan pertumbuhan ikan patin (P. hypophtalmus).  Penelitian ini menggunakan metode eksperimental laboratoris dengan rancangan acak lengkap (RAL) yang terdiri dari 5 perlakuan dan masing-masing 4 ulangan.  Perlakuan yang diujikan adalah penambahan bromelin pada pakan dengan dosis 0,00%, 0,75%, 1,50%, 2,25%, dan 3,00%.  Ikan uji yang digunakan adalah benih ikan patin (P. hypophtalmus) dengan bobot tubuh individu rata-rata 6,45±0,23 g/ekor dengan kepadatan 1 ekor/l.  Pakan diberikan 2 kali sehari, yaitu pada pukul 08.00 dan 16.00 WIB dengan menggunakan metode at satiation.  Waktu pemeliharaan ikan uji adalah selama 35 hari.  Hasil penelitian menunjukan bahwa pemberian enzim bromelin dalam pakan memberikan pengaruh yang berbeda (P<0,05) terhadap EPP, PER, RGR, dan pertumbuhan panjang relatif tetapi memberikan pengaruh sama (P>0,05) terhadap TKP dan SR.  Perlakuan dengan penambahan enzim bromelin 2,25% (perlakuan D) memberikan nilai tertinggi pada EPP, PER, RGR, dan pertumbuhan panjang relatif yaitu masing?masing sebesar 59,11±4,61%; 1,84±0,14%; 1,47±0,15%/hari; dan 0,40±0,01%/hari.  Kualitas air selama pemeliharaan ikan uji masih dalam kisaran yang layak untuk pemeliharaan ikan patin (P. hypophtalmus).  Berdasarkan hasil penelitian dapat disimpulkan bahwa penambahan enzim bromelin dalam pakan mampu meningkatkan nilai EPP, PER, RGR, dan pertumbuhan panjang relatif ikan patin (P. hypophtalmus). Feed was one of the important factors that could affect to the growth of catfish (Pangasius hypophtalmus).  Dietary protein was a major source of energy as well as structural components of cells and tissues.  Therefore, dietary protein plays an important role on the growth of the fish.  Digestion process needed enzymes to hydrolyze peptide bonds into the amino acids.  This process could be enhanced by using the bromelin incorporated into the catfish?s feed.  The purpose of this study was to examine the effect of dietary bromelain on feed utilization eficiency and growth of the catfish (P. hypophtalmus).  A completely randomized design (CRD) was used in this study with experimental laboratory consisted of 5 treatments and 4 replicates.  These treatments were the addition of bromelain in the feed with doses of 0,00; 0,75; 1,50; 2,25; and 3,00%, respectively. The experimental fish used was catfish (P. hypophtalmus) with the average individual body weight of 6,45±0,23 g/fish and with the density of 1 fish/L. The fish was fed twice a day, i.e. at 08.00 a.m. and 16.00 p.m. by applying at satiation method.  The fish was reared in 15 L containers for 35 days.  The data showed that dietary bromelain resulted on significantly effect (P<0.05) on the FUE, PER, RGR, and relatively length rate, but not significantly effect (P>0.05) on the values of FCR and SR.  The trial diet of 2.25% bromelain (treatment D) resulted on the highest values on the FUE, PER, RGR, and relatively length rate, that were 59,11±4,61%; 1,84±0,14%; 1,47±0,15%/day; and 0,40±0,01%/day, respectively.  Water quality parameters during the study were varied among suitable range for rearing the trial fish.  Based on the results, it was concluded that dietary bromelain was able to increase the values of FUE, PER, RGR, and relative lenght rate of catfish (P. hypophtalmus).

Shrimp able to thrive if cultivated properly, meet all the needs of life and no environmental interference. Feed an cultivating components that absorb the greatest costs up to 80%. Bioflok technology is an alternative to the provision of additional food protein kultivan so as to improve growth and feed effeciency. The purpose of this study was to determine the effect of the use of the system with the source bioflok C/N is different to the feed effeciency and growth of balck tiger shrimp and determine the ratio C/N which produces feed effeciency and growth of tiger shrimp are best. Free variabel parameters studied include the absolute growth, specific growth rate (SGR), the level of feed intake (TKP),  effeciency of feed utilization (EPP), survival rate (SR). Parameters of this study supports using a completely randomized design (RAL) with 3 treatments and 3 replications, namely treatment A (C/N ratio 12), treatment B (C/N ratio 18), and treatment C (C/N ratio 24). The results showed that the number of different carbon gives significant influence (P<0,01) the daily growth rate and  effeciency of feed utilization and not significant effect (P>0,05) to survival rate (SR). Ratio C/N which gives the best growth and feed effeciency was 24, with a value of  SGR 1,08±0,079%; EPP 72,32±6,17g; TKP 39,27±1,58; SR 90,00±10,00 and the water quality is still within the range for a decent life tiger shrimp (Penaeus monodon).

Abstract

Pengembangan budidaya ikan lele dumbo sering terkendala karena mahalnya harga pakan dan terjadinya infeksi penyakit. Salah satu cara untuk mengatasinya adalah dengan memberikan kombinasi pakan buatan dan cacing tanah untuk menghasilkan pertumbuhan lebih baik dan dapat meningkatkan imunitas ikan lele dumbo (C. gariepinus). Penelitian ini bertujuan untuk mengetahui profil darah lele dumbo yang diberi pakan dengan kombinasi pakan buatan dan cacing tanah (Lumbricus rubellus). Metode eksperimen dikembangkan dalam penelitiaan ini menggunakan rancangan acak lengkap (RAL) 5 perlakuan dan 3 ulangan. Perlakuan itu adalah pemberian pakan dengan 100% pakan buatan (A), 75% pakan buatan dan 25% cacing  tanah (B), 50% pakan buatan dan 50% cacing tanah (C), 25% pakan buatan dan 75% cacing tanah (D), dan 100% cacing tanah (E). Pengukuran darah seperti eritrosit, leukosit dan hemoglobin menggunakan alat hematologi analizer dan glukosa darah dengan alat spektrofotometer. Hasil penelitian menunjukkan bahwa ikan lele dumbo yang diberi pakan buatan dan cacing tanah dengan dosis yang berbeda berpengaruh nyata (P<0,05) terhadap jumlah eritrosit tetapi tidak berpengaruh nyata (P>0,05) terhadap konsentrasi hemoglobin, leukosit dan glukosa darah. Berdasarkan hasil penelitian dapat disimpulkan bahwa ikan lele dumbo yang diberi pakan buatan dan cacing tanah (L. rubellus) dengan persentase yang berbeda mengalami jumlah eritrosit 1,22?2,52x 106 sel/mm3, leukosit 102,2-135,1x 103 sel/mm3, hemoglobin 8,2-10,5 g/dl dan glukosa darah 73,3-107,1 mg/L masih kisaran yang normal. African catfish aquaculture development is often hampered by the high cost of feed and desease infection. One of the problem solving is giving a combination of artificial and earthworms for the best growth and increasing imunity of the African catfish culture. The objective of research was  to determine the effect of a combination of artificial feed and of earthworms (L. rubelus) in the description of  erythrocytes , leukocytes , hemoglobin, and blood glucose of African catfish (C. gariepinus). The experimental method was employed in this research with used completely randomized design (CRD) 5 treatments and 3 replications, respectively.  Those treatments were feeding with 100% of artificial feed (A),75%  of artificial feed and 25% of earthworm (B), 50% of artificial feed and 50% of earthworm (C), 25% of artificial feed and 75% of earthworm (D), and 100% of earthworm (E). Blood requreiment of erythrocytes, leukocytes and hemoglobin where hused by hematology analyzer and blood glucose by a spectrophotometer.  The results showed that the African catfish feed combination of artificial feed and earthworms have given significant effect(P<0.05) in the erythrocytes number but not significant effect (P>0.05) on the concentration of hemoglobin , leukocytes and blood glucose. Based on the results of this study it can be concluded that African catfish feed with artificial feed and earthworms (L. rubellus) with different percentage will have the amount of erythrocytes 1,22?2,52x 106 sel/mm3, leukocytes 102,2-135,1x 103 sel/mm3, hemoglobin 8,2-10,5 g/dl, and blood glucose 73,3-107,1 mg/L  still in the normal range.
