The Effect Extender of Young Coconut Water in 0,9% Sodium Chloride on Sperm Quality Catfish (Hemibagrus Nemurus) During Storage
This study aimed to evaluete the effect of extender coconut water and NaCl on sperm motility, viability, and fertility of riverine bagrid catfish (Hemibagrus nemurus) storage. This experiment used Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely Treatment P0: 0.1 ml sperm plus coconut water 0% + NaCl 100%, P1: 0.1 ml sperm plus coconut water 40 % + NaCl 60%, P2: 0.1 ml sperm plus coconut water 50% + NaCl 50%, P3 0.1 ml sperm plus coconut water 60 % + NaCl 40%, and P4 0.1 ml sperm plus coconut water 70 % + NaCl 70%. The results showed that the addition of coconut water and NaCl on sperm storage significantly affect sperm quality of catfish and during 96 hours of storage. The result showed that the best quality sperm of catfish treated by P2 was higher than (P<0,05) other treatment. In addition, the optimal storage time was in 48 hours, because it had very good motility and highest viability (63,861%). But after 96 hours in storage, fertility decrease until 21,80%
Induksi Triploid Ikan Selais (Kryptopterus Lympok) Menggunakan Kejutan Panas
A study was conducted to induced triploidy in fertilized egg of sheatfishlarvae , (Kryptopterus lympok) using heat shock. The eggs were exposed at 40OCfor shock duration of 1 , 3 , 5 and 0 minutes as a diploid control. Results showedthat the 5 minutes shock duration was the highest triploid induction and yield(91.7 and 62.9%). Erythrocyte analysis showed that the volume of triploid fishgroup was bigger that that of diploid one. The fertilization, hatching and survivalrate was lower in triploid groups, while SGR was higher compared to diploid fish
Comparison Natural Spawning with Artificial Spawning in Gold Fish Oranda (Carassius Auratus)
The research on the Comparisson between natural spawning and artificial spawning in gold fish oranda (Carassius auratus) was conducted in February 2014 in the Fish Hatchery and Breeding Laboratory of the Faculty of Fisheries and Marine Sciences, University of Riau. The research was to compare the result between natural spawning and artificial substrate with result artificial spawning using injection with ovaprim 0,5 ml/kg body weight females; 0,2 ml/kg body weight males in gold fish oranda (Carassius auratus). The container used in this study was 6 unit fiber size 100x60x50 cm2 The method used is an experimental method or direct observation and than process spawning one unit sampel don\u27t in simultaneously because different maturity level gold fish oranda.The results treatment showed that is natural spawning better than artificial spawning in terms of index ovisomatic 12,2 % (IOS); fertilized rate 86,8 % (FR), hatching rate 91,1 % (HR), survival rate of 10 days old fry 97,9 % (SR)
Use of Different Doses of Ovaprim to Induced Signal Barb (Labeobarbus Festivus, Heckel 1843)
This research was conducted from April to November 2015. The aim of this research was to determine the effect of ovaprim doses on spawning success of signal barb (Labeobarbus festivus, Heckel 1843). The method used in this research was an experimental method with Completely Randomized Design (CRD) with one factor, four treatments and three replications. The treatment used in this research was an injection of ovaprim with different doses i.e : P0 (0,2 mL NaCl physiology 0,9 %/kg of body weight), P1 (0,5 mL/kg of body weight), P2 (0,7 mL/kg of body weight) and P3 (0,9 mL/kg of body weight). The results showed that ovaprim dose of 0,7 mL/kg of body weight was the best in turn of latency time (5.32 hours), total eggs stripping (14.095 eggs/g gonads), egg diameter (0,91 mm), egg maturity (87,7 %), Ovi Somatic Index (20,15 %), fertility rate (40,39 %), hatching rate (14,85 %), and survival rate (38,07 %)
Feeding Strategies on Climbing Perch (Anabas Testudineus) Larvae Fed with Natural Food
A research was conducted from 3 Desember 2014 to 1 January 2015 at the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Science, University of Riau. This the growth and survival rate of Climbing Perch larvae (Anabas testudineus), fed on the natural food combinated such as Artemia naupli, water flea and Tubifex sp. The container used was 18 unit, 30x30x30 cm aquarium. The research method was experimental design with a completely randomized design (CRD) with six treatments and three replications. The treatment were A1T3 (one week given the Artemia sp and three week of the Tubifex sp). A2T2 (two week given Artemia sp and two week of the Tubifex sp). A3T1 (three week given Artemia sp and one week of the Tubifex sp). WF1T3 (one week given water flea and the three week of the Tubifex sp). WF2T2 (two week given water flea and two week of the Tubifex sp). WF3T1 (three week given water flea and one week of the Tubifex sp).The results showed that the A1T3 with the absolute weight growth (1,4850g), weight daily growth (22,55%) and the absolute length growth (40,33mm). The best survival rate in the WF2T2 (63,33%). The average % water temperature, pH and dissolved oxygen 270C, 6 and 4.8 ppm respectively
The Addition of Vitamin E in Fish Diet for Gonadal Maturity of Beardless Barb (Cyclocheilicthys Apogon, Val. 1842)
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
