Abstract

This research was conducted from July to August 2014, for 35 days in Breeding Laboratory Unit of Fisheries Faculty and Marine Sciences, University of Riau Pekanbaru. The aims of the research was to investigate rearing of river catfish (Mystus nemurus C.V) with biofloc system in aquaponic recirculation system. The method used was experiment with 3 treatments and 3 replications. The treatments were P1 = 20 ml/L of probiotic bacteria inoculant, P2 = 25 ml/L of probiotic bacterial inoculant, and P3 = 30 ml/L of probiotic bacteria inoculant. The best treatment was achieved by P3 with absolute growth weights (3.79 g), absolute growth length (6.10 cm), daily growth rate (6.54%) and survival rate 90%. The best water quality parameters recorded during in the research period was achieved by P3 ammonia (NH3) 0.33-0.72 mg/L, nitrit (NO2) 0.07-0.55 mg/L, nitrat (NO3) 0.13-1.23 mg/L, temperature 27-30 0C, pH 5-6, dissolved oxygen (DO) 3-4.5 mg/L and (CO2) 7.99-11.98 mg/L.Keywords: River catfish seed (Mystus nemurus) biofloc, Aquaponic recirculation

Abstract

The study wasconducted from 3stof May to 10th June 2017.The research to do cultivation technology faculty of fisheries and marine University of Riau.The research was conducted to determine the dose of recombinant growth hormone (rGH) of Ephinepelus lanceolatus supplemented in the commercial diet that generates the best performance on body weight, body length, specific growth rate, survival rate, feed efficiency, and feed convertion rate of river Bawal Air Tawar (Colossoma macroponum)in resirculation system.The dose of rElGH administrated was 1, 2, 3 and 4 mg/kg of commercial feed and no rGHsupplementation as control. Each treatment was design in triplicates. Pomfret fish at average 3-4 cm were reared in aaquarium in a density 10 fish/aquarium for 30 days. The fish were fed with the rElGH suplplemented diet once a three days at satiation. The results showed that growth body weight of 2 mg/kg feed was (8,25g), Specific growth rate 9,21 %, feed efficiency (107,7%), Feed convertion rate (0,96%),(P<0.05) than other treatment.Length of 2 mg/kg feed was 4,02 cm higher than other treatment, Survival rate of 3 mg/kg feed was 100 %.(P>0.05) than other treatment. Thus, supplementation rGH 2 mg/kg feed of Pomfret fish once in three days can be applied in enhance the growth Pomfret fish with a best performance of growth.Keyword: Pomfret fish, recombinant growth hormone, resirculation system

Abstract

Silk worms is one kind of natural food like fish larvae because they contain good nutrients for the growth of fish larvae. This study aims to determine the appropriate amount of fertilizer and the implementation of systems of recirculation to the growth of silk worms. The research was conducted on July 29 to September 18, 2016 placed in a field laboratory of the Faculty of Fisheries and Marine University of Riau. The media used is in the form of sludge reservoirs, dedek smooth, tofu, chicken manure and EM4. While the materials used are silk worms obtained from collectors. Experimental method used was a completely randomized design (CRD) with 3 levels of the factor treatments and 3 repetitions. The treatments used: P0: without the use of chicken manure, P1: 500 g of chicken manure / 0.098 m2, P2: 600 g of chicken manure / 0.098 m2, and P3: 700 g of chicken manure / 0.098 m2. The data observed is the growth of biomass weight, average length, and water quality. The results of this study with the treatment of chicken manure fertilizer of different very significant effect (P <0.05) on the growth of biomass weight of silk worms. Biomass is highest in treatment P3 (700 g chicken manure / 0.098 m2) in 69 g. As for the average length, chicken manure fertilizer does not affect significantly different (P> 0.05). The average length of the highest in treatment P2 (1.83 cm). Water quality measured during the study was the temperature (25-29˚C), pH (6-7), dissolved oxygen (6,0-6,5 ppm), and CO2-free (2,0-3,5 ppm). From this study it can be concluded that giving different chicken manure can affect the growth of silk wormsKey Words : Tubifex sp, sludge reservoirs, chicken manure, biomass, dan average length

Abstract

Pangasius polyuranodon Blkr is Indonesia’s endemic spesies which need to bedomesticated for species preservation. The aim of this research is to find out thetechnique to domesticate P. polyuranodon Blkr from nature habitat and keep it incontrol aquaculture system, as well as also to apply resirculation system inkeeping it so that water quality is maintained well in order to support P.polyuranodon Blkr life. The method used in this research is experiment by usingComplete Random Design (CRD), where the treatments were P0 = unfilteredresirculation, P1 = sponge filter resirculation, P2 = active charcoal filterresirculation and P3 = zeolite filter resirculation. The result of this research is P.polyuranodon Blkr enable to domesticated in control aquaculture system. Thebest treatment from this research is P3 with amonia range from 0,08 – 0,11 mg/L,nitrat range is between 0,07 – 0,11 mg/L and nitrite range between 0,07 – 0,09mg/L. The P3’s treatment produce absolute growth of 9,24 g, the increase ofspecific growth 1,76%, the growth of biomass of 62,63 gr, the feeding efficiency28,06% and survival rate of 86,66%.Keywords: Pangasius polyuranodon Blkr, domestication, filterd resirculation,water quality, survival rate.
