Abstract

This research was conducted from October 29th 2015 until November 26th 2015 at Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau. The aim of this research was to determine subtitusion (Tubifex sp.) with commercial shrimp pellets for the growth and survival Rate of climbing perch (Anabas testudineus) larvae. The method used was an experimental method by using a completely randomized design (CRD) with five treatments and three replications. Treatments applied were T4PU0 (Tubifex sp. four week), T3PU1 (Tubifex sp. three week + commercial shrimp pellets one week), T2PU2 (Tubifex sp. two week + commercial shrimp pellets two week), T1PU3 (Tubifex sp. one week + commercial shrimp pellets three week). T0 PU4 (commercial shrimp pellets four week). The results showed that larvae fed on T3PU1 (Tubifex sp. three week + commercial shrimp pellets one week), average of absolute length 3,06 cm, average of absolute weight 0,745 g, and spesific growth rate 15,41%, with the highest survival rate on T2PU2 (Tubifex sp. two week + commercial shrimp pellets two week) 86,67%. Results of water quality measurements in the temperature, pH and dissolved oxygen was 27–290 C, 4,5-6,9 and 2,3 – 6,9 ppm/L respectively.Keyword: Climbing perch larvae (Anabas testudineus), growth, survival rate, commercial shrimp pellets

Abstract

AbstractResearch on the effect of feeding frequency and feeding rate on growth, feed eficiency and survival rate of java barb larvae (Puntius javanicus Blkr) was conducted on 26 June-4 August 2018 at the Fish Hatchery and Breeding, Pinang Mancung Tebing Tinggi, North Sumatra. In this research the larvae were rearing in aquarium sized 40x30x30 cm filled with 15 L of water. Each aquarium was stocked two larvae per L.The experimental design useda completely randomized design (CRD) with two factors, namely feeding frequency with three levels: two times/day (F2), three times/day (F3) and four times/day (F4). The second factor was the feeding rate with three levels: P25 (25 %of  body weight), P50 (50 % of body weight), P75 (75 % of body weight).To minimize errors, each level of treatment was repeated 3 times. The best growth rate in the treatment of F4P75 (feeding frequency four times/day with feeding rate 75% of body weight)with an absolute weight of 2.45 gr, absolute length 3.45 cm, average growth rate of 14.78 %/day, feed eficiency 24.56 % and survival rate 98.88 %. The condition of water quality is the water temperature 24,6-27,90C, pH 5,3-6,7 and dissolved oxygen 5,1-6,0 mg/l. Keywords : Puntius javanicus Blkr, feeding frequency, feeding rate, growth, feed eficiency, survival rate.

Abstract

The addition of vitamin E in fish diet for the gonadal maturity of beardless barb (C. apogon Val 1842) was carried out in fish Hatchery and breeding laboratory, Universitas of Riau from July to october 2015. The brooders collected from Kampar river were acclimitized for several weeks before used. The fish were reared in 12 weeks in tool recirculated water system fiber glass tanks at stocking density of 7 fish/tank. The fish were fed with dry pelled containing 35% protein at satiation. The experiment used a completely randomized design and each treatment had three replicates. The treatment were the dosage of Vitamin E i.e. P0 (0 mg/kg) as control, P1 (100 mg/kg), P2 (200 mg/kg), P3 (300 mg/kg). Result of experiment showed that the addition of 300 mg Vit. E / kg feed was better than dosage, in term of the number of fish reaching mature level (Fourth Stage) (7 fish), Gonad Somatic Index (7,93 %), Fecundity (2678 eggs) and egg diameter (0,706 mm)Key words :Beardless Barb (C. apogon, Val. 1842) Vitamin E, Reproduction quality

Abstract

AbstractThe aim of this research was to determine the effect of stocking density and feeding rate on growth and survival rate of ingir-ingir larvae. This research was conducted from September-Oktober 2018 at Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty Riau University. The Method used was a Factorial Completely RandomizedDesign with two factors, the first was stocking density with three levels namely 5 larvae/L (S5), 10 larvae/L (S10) and 20 larvae/L (S20). While the second factor wasfeeding rate 40% (F40), 60% (F60) and 80% (F80) of biomass.To minimize errors, each level of treatment was repeated 3 times. The result showed that stocking density and feeding rate were significant on absolute weight, absolute length, average growth rate, survival rate and feed efficiency. The treatment S5F80 (5 larvae/L and feeding rate 80% of biomass weight) were significant(P<0,05) with an absolute weight of 0,67 g, absolute length 3,65 cm, average growth rate of 16,28 %/day, feed eficiency 14,59 % and survival rate 91,33 %. The water quality parameters during research was in optimal range temperature 26,4-27,5°C, pH 5-6and dissolved oxygen 3,6-4,51 mg/l. Keywords : Stocking denstity, Feeding Rate, Growth and Survival rate

Abstract

The research on rearing of green catfish larvae (Hemibagrus nemurus) with different protein source of paste feed was carried out for 40 days in the Laboratory of Fish Hatchery and Breeding Faculty of Fisheries and Marine Sciences University of Riau. The aim of this study was to evaluate the substitution of tubifex worm with different protein sources of paste feed. Protein sources used were squid meal, fish meal, cockle meal and mysid meal. The effect on growth and survival was determined.Result showed that tubifex worm cauld not be substituted by the paste feed in rearing green catfish larvae for 40 days rearing period. Among the paste feed, the squid meal protein source paste feed was the best and more efficient in term of highest survival rate and the lowest cost per fish.Keywords: paste feed, growth, survival Hemibagrus nemurus larva

Abstract

ABSTRACT The aim of this study was to evaluate the effect offeed types of fresh Tubifex worm, frozen Tubifex worm, mixed Tubifex (fresh and frozen) and frozen blood worms on the growth of survival of sheetfish larvae and to know the best type of feed between frozen Tubifex sp and frozen blood worms which can be used as an initial feed for sheetfish larvae other than fresh Tubifex sp reared in a recirculation system. This experiment used Completely Random Design (CRD) with 4 treatments and 3 replications, namely P1:  feeding the fresh Tubifex, P2: feeding the frozen Tubifex, P3: feeding the frozen blood worms, P4: Feeding the combination feed (fresh and frozen) with frozen blood worms. The results showed that there was an effect of feeding Tubifex sp and frozen blood worms on the growth and survival of sheetfish fish larvae (Ompok rhadinurus). The best treatment, P1with fresh Tubifex sp which produces an average growth of absolute weight of 5,14 grams, absolute length 8,76 cm, growth rate of 14,95% / day weight and 100% survival. Water quality parameter values are temperature of 270C - 280C, pH 5,6-5,7 and dissolved oxygen (DO) between 3,3-6,0 mg/l. Keywords : Tubifexsp, frozen blood worms, ikan selais (Ompok  rhadinurus).

Abstract

ABSTRACT                This studywas conducted from May-August 2017 at the Laboratory of Hatchery and Fish Breeding, Marine and Fisheries Faculty University of Riau, Pekanbaru. The objective of this research was to evaluate the intergeneric hybridization between Common carp (Cyprinus carpio L) and Comet goldfish (Carassius auratus). Percentage of Fertilization, hatching, growth, survival in seven days (SR-7), survival rate in thirty days (SR-30),heterosis value, and to know the morphometric and meristic characteristics of hybridized seeds. The method was an experimental method with a Completely Randomized Design (CRD), one factor three times repetition. Spawning is induced breeding using ovaprim hormone with a dose of 0.5 ml/kg. The cross was done by fertilizing the Common carp eggs with Comet goldfish sperm and otherwise the comet fishgold egg is fertilized with Common carp sperm.            The results showed thathybridization was successfully. Heterosis of hybrid results positive to SR-7 parameter while the other parameters are negative. The hybrid ♀Cg × ♂Cc results have an advantage to FR, HR and SR values while the ♀Cc × ♂Cg hybrid results excel to absolute weight and length growth parameters.In general, hybrid seeds tend towards the common carp at a ratio of body width, head width, and head length to total length, while towards comet goldfish the character of height to total length compared. Keywords: intergeneric hybridization, growth, morphometric, common carp, comet goldfish
