“…The decline of growth in O. marmorata when fed with high dietary lipid diets indicates a limited or absence of protein sparing effect of lipid. This result is in agreement with those in other fish species including turbot Psetta maxima (Sevgili et al, 2014) and blunt snout bream Megabrama amblycephal (Li et al,2010). However, protein sparing effect was reported in rockfish juvenile Sebates schlegeli by (Lee et al, 2002) who recorded significantly better protein utilization, weight gain, feed efficiency, ADC of protein and lipid in fish fed with 42% protein and 14% lipid compared to those fed with 49% protein and 7% lipid.…”

The present study was conducted to investigate the growth performance and feed utilization of marble goby,Oxyeleotris marmorata, juveniles fed with different levels of dietary lipid. Juvenile fish (initial mean weight 2.76 g) were fed with is onitrogenous diets including 10, 14, 18 and 22% of dietary lipid in triplicate groups for 15 weeks. The results showed that the highest growth performance and feed utilization was observed in fish fed D10. The increase of dietary lipid from 10 to 22 % did not improve growth, feed conversion rates, protein efficiency ratio, nitrogen retention efficiency, and apparent digestibility coefficients of protein and lipid (P>0.05). The increase of dietary lipid had significantly increased the whole body and hepatic lipid, hepato-somatic index, visceral-somatic index and intraperitoneal fat levels (P<0.05). These results suggest that there is no protein sparing effect of high dietary lipid levels in O. Marmorata due to possibly a limited ability to utilize dietary lipid. Based on the second-order polynomial regression analysis on protein efficiency ratio, ca. 12.1% of dietary lipid appears to be optimumfor growth from 2.76g to 13.76g body weight of O. marmorata juveniles.

ABSTRAKProtein merupakan nutrien yang sangat berperan dalam pertumbuhan ikan. Penelitian ini bertujuan mengetahui kebutuhan protein optimal untuk pertumbuhan ikan Tor tambroides dan pengaruh kandungan protein pakan terhadap efisiensi pakannya. Benih ikan Tor yang digunakan berukuran panjang (1,5 ± 0,1 cm) dan bobot (0,08 ± 0,01 g). Benih ikan dipelihara dalam akuarium berukuran 40 cm x 30 cm x 30 cm dengan ketinggian air 20 cm sebanyak 50 ekor. Selama 40 hari pemeliharaan benih ikan diberi pakan komersil berupa crumble dengan kandungan protein, (A) 25%, (B) 35%, dan (C) 50% sebanyak 20% per hari dari total biomassa ikan, pemberian pakan dengan frekuensi tiga kali sehari. Rancangan penelitian menggunakan rancangan acak lengkap dengan tiga perlakuan dan tiga ulangan. Hasil penelitian menunjukkan ikan Tor tambroides yang diberi pakan dengan kandungan protein sebesar 35% dan 50% memiliki pertumbuhan panjang, bobot, laju pertumbuhan harian (LPH), biomassa, nisbah konversi pakan (FCR), dan efisiensi pakan yang sama (P>0,05) dan berbeda nyata pada pakan dengan kandungan protein 25% (P<0,05).

“…Hasil yang sama dilaporkan terjadi pada ikan silver barb P. gonionotus (Mohanta et al, 2008) dan juvenil bluefin trevally Caranx melampygus (Suprayudi et al, 2013) sedangkan Babalola and Apata (2006) melaporkan nilai IHS dari Heterobranchus longifilis nyata dipengaruhi oleh kadar protein pakan. Sementara itu, perbedaan nyata penurunan nilai IHS dengan meningkatnya kadar protein dilaporkan terjadi pada M. amblycephala dan Godus morhua (Li et al, 2010;Arnason et al, 2010).…”

PENDAHULUANAnguilla bicolor bicolor merupakan salah satu jenis ikan sidat yang banyak dibudidayakan di Indonesia dan termasuk ke dalam jenis ikan karnivora yang memiliki pertumbuhan yang lambat. Pertumbuhan ikan sidat dalam satu siklus pemeliharaan dari benih ukuran glass eel (0,09-0,12 g) mencapai ukuran konsumsi (250 g) membutuhkan waktu sembilan bulan sampai dua tahun bahkan beberapa di antaranya terhenti pada ukuran 2-3 g. ABSTRACTThe study was aimed to determine the optimum dietary protein level and energy protein ratio which can optimize growth performance of the eel A. bicolor bicolor on nursery phase. Four treatments and three replications were applied in this study. The treatments were P1, containing 37.66% protein with energy protein ratio 14.75 kcal GE/g (37.66%; 14.75 kcal GE/g), treatment P2 (41.30%; 13.51 kcal GE/g), treatment P3 (45.38%; 12.27 kcal GE/g), and treatment P4 (49.60%; 11.31 kcal GE/g). Eels used for this study were 6.5±0.3 g in average body weight. Eels were reared in a series of aquaria with dimension 90×40×40 cm 3 and filled with 100 L of fresh water. Total weight of eel stocked in aquarium were 400 g. Eels were fed until satiated twice a day at 8 am and 4 pm for 60 days. The result showed that different protein level and energy protein ratio was significantly affected growth performance (feed consumption, specific growth rate, feed efficiency, protein retention, and lipid retention), protein and fat of whole body eels at confident limit of 5%. In contrary, there was no significant different on the survival rate, hepatosomatic index, ash content, and nitrogen free extract of the body eel. The optimal growth performance was reached by dietary protein level and energy protein ratio of 45.38%; 12.27 kcal GE/g and 49.60%; 11.31 kcal GE/g. Keywords: Anguilla bicolor bicolor, energy protein ratio, feed, growth performance, protein ABSTRAKPenelitian ini bertujuan menentukan kadar protein dan rasio energi protein optimum yang dapat meningkatkan kinerja pertumbuhan ikan sidat A. bicolor bicolor fase pendederan. Empat macam perlakuan dan tiga ulangan digunakan dalam penelitian ini. Perlakuan tersebut adalah P1 yang mengandung protein 37,66%; dengan rasio energi protein 14,75 kkal GE/g (37,66%; 14,75 kkal GE/g), perlakuan P2 (41,30%; 13,51 kkal GE/g), perlakuan P3 (45,38%; 12,27 kkal GE/g) dan perlakuan P4 (49,60%; 11,31 kkal GE/g). Bobot rata-rata ikan sidat yang digunakan adalah 6,5±0,3 g. Ikan sidat dipelihara dalam akuarium berukuran 90×40×40 cm 3 dengan volume air 100 L. Total bobot ikan yang digunakan dalam setiap akuarium adalah 400 g. Ikan sidat diberi pakan sekenyangnya dengan frekuensi dua kali sehari yaitu pukul 08.00 dan pukul 16.00 WIB selama 60 hari. Hasil menunjukkan bahwa pemberian kadar protein dan rasio energi protein pakan berbeda, memberikan pengaruh nyata (P<0,05) terhadap kinerja pertumbuhan (jumlah konsumsi pakan, laju pertumbuhan spesifik, efisiensi pakan, retensi protein, retensi lemak), protein tubuh dan lemak tubuh, tetapi tidak berpengaruh nyata (P>0,05) terhadap t...
