Abstract

ABSTRACT The aim of the study was to determine the optimal doses of boster grotopin increasing the growth and survival of baung fish (Hemibagrusnemurus) in the recirculation system. This research was conducted from Augustuntil October 2019 for 40 days at the Technology LaboratoryAquaculture Faculty of Fisheries and Marine Riau University. Which methodused in this study is an experimental method, usingComplete Random Design (CRD) with 5 levels of treatment and 4 replications.The treatments applied were: P0) 0 g / kg of feed; P1) 15 g / kg of feed; P2) 20 g / kg of feed; P3) 25 g / kg of feed; P4) 30 g / kg of feed. The results showed thatthe addition of a different dose of booster grotopes shows a real effect(P<0.05) to growth in absolute weight (Wm), growth in absolute length(Lm), specific growth rate (LPS), feed efficiency (EP), feed conversion ratio(FCR) and have no significant effect (P>0.05) on the survival rate (SR)baung fish. The best treatment is giving grotop booster 30 g / kg of feed(P4) which produces an absolute weight growth of 3.86 g, long growthabsolute 2.41 cm, specific growth rate 1.62%, feed efficiency 83.55%, feed conversionratio 1.19% and survival 96.67%.Keywords:Doses,BosterGrotop, Recirculation System, Growth,Baung Fish.

This study uses an experimental method with a completely randomized design (CRD) of one factor with 4 treatment levels and 3 replications. The dose of astaxanthin in the treatment were: 0% astaxanthin, 1% astaxanthin, 3% astaxanthin, 5% astaxanthin. The size of fish was used is 3-5 cm with 10 stocking densities per aquarium. Maintenance lasts for 30 days and feed is given as much as 3% of the weight of biomass, the frequency of feeding is 3 times a day. Parameters observed included fish color, absolute length growth and absolute weight, survival rate and water quality. The results showed that the administration of astaxanthin had a significant effect on changes in the quality of the color of the Tiger Barb. The best treatment was at a dose of 5% which improved the quality of chest color 12.77, body 9.16, tail 14.00. The best absolute length growth is 0.55 cm, absolute weight is 0.47 grams and fish life is 100%. Keywords: Astaxanthin; Color; Tiger Barb; Puntius tetrazona

ABSTRACK This study aims to determine the best dose of aquavita premix booster in enhancing growth, feed efficiency and survival of baung fish. Research containers used in the form of aquariums measuring 60cm x 40cm x 40cm as many as 20 aquariums with a stocking density of 15 animals / aquarium. This study used aRandomized Design (CRD) consisting of five levels of treatmentand four replications. Each treatment was given the addition of aquavita premix of P0 (0 g / kg), P1 (1 g / kg), P2 (2 g / kg), P3 (2 g / kg), P4 (3 g / kg), and P5 (4 g / kg) feed.

Abstract

                                      ABSTRACT The purpose of this study was to determine the effect of adding carrot flour (Daucuscarrota L) to artificial feed on the brightness of the color of Tiger barb. The method used in this study is the experimental method using a completely randomized design (CRD) of 1 factor with 4 levels of treatment, and 3 replications.The dose of carrot flour in this study was 0% (control), 5%, 10%, 15%. The feed was tested on Sumatran fish measuring ± 3 cm long which was maintained in an aquarium measuring (30x40x40) cm3. The parameters measured include the brightness of the color, growth, survival, and water quality. The results showed that the addition of carrot flour to feed can increase the color of Tiger barb. The best dose is 15% which can increase the brightness of color 3.53, absolute weight growth of 0.54 grams, and growth of absolute length of 0.65 cm.

Abstract

The study was conducted in January-March 2018, field analysis (insitu) was conducted in Sungai Paku Reservoir of Sungai Paku Village Kampar Kiri Sub-district Kampar District Riau Province. Laboratory analysis (exsitu) was conducted in Ecology and Waters Management Faculty of Fishery and Marine Science University of Riau Pekanbaru. The purpose of this research is to analyze the quality of Sungai Paku reservoir to the floating net cage (FNC) activity, to analyze and develop the socialization of FNC management in the Sungai Paku reservoir. This research uses survey method, by conducting direct measurement in the field, conducting analysis and interviews of research location through questionnaire to get more accurate data. To analyze the environment at about 3 different stations over the inlet of the reservoir, within the FNC area, and outlet of the reservoir. Physical chemistry parameters include 95-95.2 cm Brightness, temperature 30-30.3oC, current velocity 3.92 - 3.97, dissolved oxygen 0.98 - 1.00 mg / l, pH 5, Phosphate 0.1850-0.1851 mg / L, nitrate 0.2102-0.2104 mg / l , ammonia 0.0675-0.0677 mg / l. The average abundance of phytoplankton 17,600 - 22,400 cells / ml. Abundance of macrozoobenthos 866 - 1471 Ind / m2. Evaluation of water quality at each observation station indicates that the recording at each station is DO, pH and total P which have not meet the standard of water quality.
