Abstract

Productivity of Cryptopterus spp (Selais Janggut fish) in Kuantan Singingidistrict has decreased each years. This indicates that Cryptopterus spp extinctconditions and should be a priority for recovery and restocking this fish to freshwater of Kuantan Singingi district. To recovery this fish can be done byaquaculture in cages method and restocking this fish in to freshwater byconsidering the type and environmental conditions in each type of public watersKuantan Singingi. Policy strategy in the management of fish stocks was tomanage of fishing area and by management of the conservation area of fresh waterand development of cage aquaculture program in fresh waters .Keywords: Cryptopterus spp, fish stocking, fresh water

Abstract

This study was conducted at fish breeding and hatchery laboratory ofFisheries and Marine Science Faculty, University of Riau. Mature female ofselais fish used in the study were between 45-50 g body weight and male fishwere between 44-55 g body weight. Study method used in the study wasexperimental method,while data was analised by descriftive method. Theresultsof the study show that the highest percentage of fertilized eggs found on thetreatment of D0, 3W7 (fish injected with sGnRH + Domperidon 0,3 ml/kg andlaten time of 7 hours), and the highest percentage of eggs hatch was found on thetreatment of D0,5W8 and D0,7W6. However, treatment without injection withsGnRH + domperidon was no single fish was ovulated. Water quality duringexperiment was always in good condition for living.Keywords: Ompok rhadinurus Ng, sGnRH + Domperidon, ovulation. fertilizedeggs, laten time.

Abstract

AbstractThe aim of this research was to determine the effect of stocking density and kind of food on growth and survival rate of north african catfishlarvae reared with a water recirculation system. This research was conducted from March-April 2019 at the 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 10 larvae/L (T10), 20 larvae/L (T20) and 30 larvae/L (T30). While the second factor waskind of feed with two levels namely Tubifex worm and Pasta feed. The larvae were reared in 10 L-glass aquarium with a water recirculating system for 40 days. The result showed that stocking density and kind of feedgave asignificant effect in absolute weight, absolute length, specific growth rate and survival rateof north african catfishlarvae reared in 40 day. The larvae stocked at density of 10 larvae/L and fed on Tubifex worm were significanthythe highest in absolute weight (2,40 gr), absolute length (7,76 cm), spesific growth rate (14,93 %/day) and survival rate (96,00 %). The water quality parameters during research were rangedtemperature26,2-26,8°C, pH 5,2-6,1and dissolved oxygen 3,5-5,2 mg/l. Keywords : Stocking denstity, Kind of feed,North african catfishlarvae

Abstract

The research was conducted from January to March 2016 at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Science University of Riau Pekanbaru. The aim of this research was to evaluate suitable feed for the maturation of the gonad of bagrid catfish (Mystus nigriceps) reared with different feeding treatment (Commercial feed; cookle meat; soilworm(annelid) and chopped fresh fish. The research method used was Completely Randomized Design (CDR) with four treatments and three replications. The result showed that chopped fresh fish (Poecilia reticulata) and commercial dry food were the best food for maturating the fish gonad of bagrid catfish (Mystus nigriceps). Total fish reached matured stage IV was 16 fish (88,89%), gonad somatic index 9,06 %, relative fecundity 835 eggs/g fish, egg diameter 0,85 mm. The temperature range from 28 – 310C, pH 5 – 6, DO 5,7 – 6,8 ppm.Keyword: food types, Gonad maturation, bagrid catfish

                                                 ABSTRACTThe study was conducted on March in the Laboratory of Fish Hatchery and Breeding at the Faculty of Fisheries and Marine Sciences and Photomicrograph Laboratoryat The Faculty of Mathematics and Natural Sciences, University of Riau. The aim of this study was to evaluate the effect of different glycerol concentrations to milk extender on sperm motility, viability, fertility and hatching rate of sheat-fish (Ompok rhadinurus Ng, 2003) during short storage. This experiment useda Factorial Complete Random Match (CRD) one factor with 5 treatments and 3 replications, namely: P0 : 0% Glycerol in 100% milk extender, P1 : 1% Glycerol in 99% milk extender, P2: 2% Glycerol in 98% milk extender, P3 : 3% Glycerol in 97% milk extender and P4 : 4% Glycerol in 96% milk extender. Semen of this experiment was found from 35 males of sheat-fish and stored in the refginerator with 4 oC of temperature. The result showed that different glycerol concentrations to milk extender significantly affected to sperm quality of self-fish (Ompok rhadinurus Ng, 2003) during 96 hours storage (P<0.05). The result showed that P4 (4% Glycerol on 96% Milk Extender) was the best treatment with 76 hours of optimal storage time, it caused by sperm motility that was still good (3) with 47,8% viability. The fertility in 12 hours of storage was 87% with 89,6% hatching rate. But in 96 hours of storage fertility decreased until 45,3% with 53,3% hatching rate. Keyword :Ompok rhadinurus Ng, 2003, Glycerol, Milk Extender, Sperm Quality

Abstract

This study was conducted from May 16 until July 4 2016 in the fish hatchery and breeding laboratory, Fisheries and Marine Sciences Faculty of Riau University. The purpose of this study was to determine the influence of light (dark, light, sunlight) and the type of feed (Tubifex sp and pellet) on colour quality, growth and survival rate Platy fish (Xiphophorus helleri). Experimental method used in this study was completely randomized design with factorial 3 x 2 x 3. The first factor was light consist of dark light, bulb light and sun, while the second factor was type food (Tubifex sp. feed and TAKARI pellet) with three replications. The fish was reared in 3 L aquarium those reared with dark and bulb light were dow inside and that with sun light was dow outside.The result showed that the best treatment from that all is to giving sunlight and feed the platy with Tubifex sp and the sunlight given TAKARI Pellet feed can improve the colour quality till level 30 of sunlight level. Treatment with feed Tubifex sp provide the absolute best length of 2.40 cm and the fish weights from the absolute best in sun light treatments with feed Tubifex sp can increase to 0.34 g. The Best survival rate in treatment without light / dark, sunlight, lamplight with feed Tubifex sp and sunlight, lamplight with Pellet feed TAKARI of 94.44%. and for the Results of water quality measurements: temperature ranging from 26.1 to 31.3 ° C, pH range between 6.6 to 7.3 and DO ranged from 4.2 to 6.3 ppm.Key word: the colour quality of fish, Xiphophorus helleri, Growth, Survival Rate

This research was conducted from October-December 2019 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine, University of Riau. The Method used was a Factorial Completely RandomizedDesign with two factors.The first was surface area of aquarium with three levels, namely 30x30x30 cm3 (Lp1), 30x40x30 cm3 (Lp2) and 30x50x30 cm3(Lp3). While the second factor was stoking density with three levels namely 250 larvae/m2 (Pt1), 500 larvae/m2, 1000 larvae/m2. The larvae were reared in 15 L aquarium for 40 days. The result showed that surface area and stocking density gave a significant effect in absolute weight, absolute length, specific growth rate and survival rateof siammese catfish larvae reared in 40 day.

Abstract

ABSTRACT          The study was conducted on 18-30 March 2018, at the Fish Hatchery of Tebing Tinggi, North Sumatera. The purpose of the study was to determine the effect of thyroxine hormone immersion doses on egg hatching rate, larvae growth and survival rate of larvae (Puntiusjavanicus Blkr). The research method was experimental design. the dose of thyroxine hormone solution used was P1 (0 mg / L), P2 (0.05 mg / L), P3 (0.10 mg / L) and P4 (0.15 mg / L) for 24 hours. The results showed that the dose of thyroxine hormone gave a very real effect to egg hatching rate (83,3%) and survival rate (86,67%) of larvae, but did not give significant effect to growth and larvae abnormalitas. The best dose of thyroxine hormone to increase egg hatchability and of larvae growth was 0.15 mg / L and 0.10 mg / L. The water quality parameters during the study were temperature 26-28oC, pH 6.9-7.9; DO 5,4-5, ppm..Keywords:Hatching rate,Thyroxine, Growth, ,larvae.
