    An Improvement of Carcass Quality of Harvested Cage Cultured Catfish (Mystus nemurus) by Increasing Protein Level in the Diets
    (2016-03-31) Hasan, Bustari; Suharman, Indra; Desmelati; Iriani, Dian
    Two diets containing 40% protein, P/E ratio 1.30 g/kcal (high protein) and 34% protein, P/E 1.07 g/kcal (low protein), which produced the best growth at our previous experiment, were fed to Mystus catfish to determine their carcass quality. The fish ranging from 40.14 g to 42.64 g in size was grown in commercial fish cages (4x4x1.5 m) at a density of 50 fish per m3 for 90 days. The fish were fed the experimental diets at libitum twice daily, at 9.00 and 16.00. The harvested fish was evaluated for carcass quality characteristics and growth performance. Edible flash, dressing percentage and water holding capacity of harvested fish were higher for the fish fed higher protein diet than that for lower protein diet (P<0.05); but carcass waste was higher for the fish fed lower protein diet than that for higher protein diet (P<0.05). There was no significant different in hematosomatic index between the two fish groups (P>0.05). Proximate composition of the harvested fish was significantly different between fish fed higher and lower protein diet, except moisture. Protein and ash composition was higher for fish fed higher protein diet than that fed lower protein diet (P<0.05), however, fat composition was higher for the fish fed lower protein diet than for that fed higher protein diet (P<0.05). The fish fed higher protein diet consumed less feed but more protein (P<0.05); however, feed and protein efficiency as well as protein retention were not different between the two fish groups (P>0.05). Weight gain was higher for fish fed lower protein diet but protein gain was higher for fish fed higher protein diet (P>0.05).

    Pemanfaatan Bahan Baku Alternatif Sebagai Sumber Protein Dalam Pakan Untuk Memacu Pertumbuhan Benih Ikan Baung (Mystus nemurus CV)
    (2015-04-16) Suharman, Indra; Asiah, Nur
    Penelitian ini bertujuan mengetahui persentase tepung eceng gondok terfermentasi yang terbaik dalam formulasi pakan untuk meningkatkan pertumbuhan dan efisiensi pakan ikan baung. Percobaan ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 3 ulangan, yaitu penggantian tepung kedelai dengan tepung eceng gondok terfermentasi masing-masing sebesar 0% (P1), 10% (P1), 20% (P2), 30% (P3), dan 40% (P4) dengan kandungan protein pakan sebesar 30%. Ikan uji yang digunakan dalam penelitian ini adalah benih ikan baung berukuran bobot rata-rata 6.3-6.9 gram dengan padat tebar 15 ekor per wadah percobaan. Ikan uji diberi pakan sebanyak 10% dari bobot biomassa dengan frekuensi pemberian tiga kali sehari, yaitu pukul 07.00, 12.00 dan 17.00 WIB. Berdasarkan hasil penelitian dapat disimpulkan bahwa tepung eceng gondok terfermentasi dapat digunakan untuk mensubstitusi tepung kedelai pada pakan benih ikan baung. Tingkat substitusi tepung eceng gondok terfermentasi yang terbaik adalah dengan tingkat substitusi sebesar 10% tepung eceng gondok terfermentasi + 90% tepung kedelai.

    Pengelolaan Potensi Alam Dan Pengolahan Ikan Kreatif Menuju Eduekowisata Di Desa Buluhcina Sub Das Sungai Kampar Kecamatan Siak Hulu
    (wahyu sari yeni, 2018-11-06) Yustina, Yustina; Suharman, Indra; Nursal, Nursal
    Jarak tempuh desa Buluhcina yang cukup dekat dari kota Pekanbaru (Pusat Kota Provinsi Riau), kebanyakan penduduk telah memiliki sarana transportasi berupa kendaraan roda dua serta jalan dengan keadaan yang terbilang bagus. Hal ini tentunya sangat mendukung perkembangan perekonomian dan pelaksanaan Desa Buluhcina. Wilayah Desa Buluhcina termasuk dataran rendah, yang sebagian besar terdiri dari tanah perkebunan dengan kesuburan tanah cukup tinggi, sehingga hasil perkebunan sangat mendukung kesejahteraan masyarakat

    Penggunaan Tepung Bungkil Kedelai Sebagai Bahan Substitusi Tepung Ikan dalam Pakan Ikan Baung (Mystus nemurus C V )
    (2012-12-03) Suharman, Indra; Adelina
    This experiment was conducted to examine the utilization of defatted soybean meal (SBM) as a fish meal (FM) substitute in the feeds for freshwater catfish {Mystus nemurus C V ) . The levels o f substitution of F M by S B M were 0, 25, 50, 75 and 100% o f dietary protein, respectively (Diets A . B, C , D and E. respectively). The diets were formulated to contain 35%) protein. Diets were fed to experimental fish twice daily at a feeding rate o f 10%) body weigh: per day for 56 days. A substitution level of 25%) (diet B) resulted in the highest absolutely growth rate, specific growth rate, feed efficiency, and protein retention. Based on the evaluation of these parameters, it is concluded that defatted soybean meal (SBM) can substitute 25% o f the protein for fish meal in the diets of freshwater catfish {Mysliis ricmiinis C V ) .

    Preliminary Study on the Reproduction of Geso (Hemibagrus wyckii, Bagridae ) Fish from Kampar Kanan River, Indonesia
    (2016-08-28) Aryani, Netti; Suharman, Indra; Hasibuan, Saberina
    Hemibagrus wyckii is one of vulnerable Bagridae species that inhabit the Kampar Kanan Rivers, Riau, Indonesia. A preliminary study on the reproduction of the H. wyckii has been conducted from April to August 2015 in order to determine the reproductive aspects of this fish. The number of fishes sampled was 45. The fish was captured by fishermen using fishing lines. Parameters measured were total length (cm), body weight (g), sex and reproductive condition of the fish, including gonadal maturity stages, fecundity, egg diameter, and spawning type. The eggs were preserved in Gilson solution and the diameter was measured. The fecundity was calculated using a gravimetric method. Results obtained shown that 36 males (TL 42.9 to 65.2 cm and BW 961-2,898 g) and 9 females (TL 56.4 to 79.2 and BW of 1,910 to 4,710 grams) were captured. Gonadal Somatic Index of the male ranged from 0.6 to 2.00% and that of the female was 0.88-3.97%. The fecundity range from 3,876-9,588 eggs and the egg diameter was range from 1.04-2.81 mm. Data obtained indicate that the type of the oocyte development of H.wyckii is asynchronies with partial spawning.

    Utilization of Freshwater Snail Meal in Paste Feed as a Protein Source for Growth and Survival Rate of Baung (Hemibagrus nemurus) Larvae
    (2016-03-31) Aryani, Netti; Suharman, Indra; Adelina; Sari, Mira Rahmita
    A research was conducted from Januaryt until March 2013 at Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty Riau University. Its aim was to evaluate replacement of protein source from fish meal (FM) to freshwater snail meal (FSM) on Baung larval rearing. Combination of the diet used in this study were: P0 (0% FSM, 100% FM), P1 (25% FSM, 75% FM), P3 (50% FSM, 50% FM), P4 (75% FSM, 25%FM), and P5 (100%FSM, 0% FM). The larvae were reared in 15 litre aquarium for 40 days at stocking density 2 larvae/l. Feeding was given 3 times/day. Freshwater snail flour can be replaced fish meal as a protein source paste feed in fish larvae rearing of Baung. Replacement of freshwater snail meal to fish meal can be done up to 50-100% resulting weight growth 0.89 to 1.16 g, length growth rate 3.7 to 4.0 cm, specific growth rate 9.52 to 10.19% and survival rate 69-75%.A 100% freshwater snail meal was the the most efficient paste feed to produce 40 days green catfish larvae.
