ABSTRACT This study aims to determine of this the best dose of carrot flourin increasing the brightness ofcolorCarassiusauratus. The method ofthis research was using the experimental method with Completely Randomized Design(CRD) by using one factor of 4 treatment levels and 3 replications. The treatments each dose of carrot flour were using0% (control), 5%, 7% and 9%. The fry size was around 3-4 cmthen reared in the aquarium by 15 L of water and 10 fishes ofstocking density each aquarium. The fish were reared for 40 days, three times a day of feeding frequency. The results showed that thebest treatment wasP4 dose of carrot flour 9%by giving absolute thebest color brightness with value 11,73, weight growth for 1.59 g, absolutelongevity for 1.57 cmand fish survival for 100%. The conclusion is different dose of carrot flour significantly affect the color brightnessandgrowth performance ofCarassiusauratus. Keywords: Daucus sp.; Color quality;Growth;Carassiusauratus.

Abstract

ABSTRACTThis study aims to determine the combination of natural food with the best artificial feed for growth and survival of maanvis fish (Pterophyllumscalare). The method of this research was using the experimental method with Completely Randomized Design (CRD) by using one factor of 5 treatment levels and 3 replications. The combination of feed in treatment is: 1: 100% Tubifexsp, 2: 75% Tubifex sp. + 25% pellets, 3: 50% Tubifex sp. + 50% pellets, 4: 25% Tubifex sp. + 75% pellets, and 5: 100% pellets. The fry size was around 2-4 cm and weight was 1,32 g then reared in the aquarium by 10 L of water and 10 fishes of stocking density each aquarium. The fish were reared for 40 days and feed is given as much as 10% of biomass weight, e times a day of feeding frequency.Parameters observed included absolute length and weight growth, specific growth rates, survival rates and water quality. The results showed that the best treatment was 100% Tubifexsp by giving absolute weight growth for 1,76 g, absolute longevity for 2,06 cm, specific growth rate for 1.91% and fish survival for 98%. The conclusion is different types of natural diets significantly affect the growth performance, and survival rate of maanvis fish (Pterophyllumscalare). Keywords: natural and artificial feed; Growth; Survival rate; Maanvis; Pterophyllumscalare

ABSTRACTThis research aims to determine the optimal Biolacto probiotic boster dose on feed mixing to improve feed efficiency, growth rate and survival of coriander (Ompok hypopthalmus) in recirculation systems. The research was conducted for 40 days from February to April 2019. This research was conducted at the laboratory f aquaculture technology Faculty of Fisheries and Marine Sciences, Riau University. The experiment method was done experimentally using a Completely Randomized Design (RAL) which consists of 5 treatments and 4 replications, is treatment 1). 0 mL/kg of feed (control); 2).3 mL/kg of feed; 3).5 mL/kg of feed; 4).7 mL/kg of feed; 5).9 mL/kg of feed. The results of this study showed the addition of probiotics Biolacto in the feed to give effect to the growth rate of daily seeds of sheatfishes, feed efficiency and feed conversion ratio. The addition of probiotics at 9 mL/kg of feed gave the highest yield on the daily growth rate of 1.89%, the highest yield on feed efficiency of 84.61% and the best feed conversion ratio of 1.18. However, survival was not significantly different between treatments.Keyword : Sheatfishes, Probiotic Boster Biolacto, Resirculation system

Abstract

ABSTRACT             Mudcrabs (Scylla serrata) are one of the fisheries commodities that have high economic value. Feed is the most important production factor in the cultivati of mud crabs. To determine the effect of appropriate feeding frequency and find out the best frequency for the growth and survival of mudcrabs (Scylla serrata). The method used in this study was to use a Completely Randomized Design (CRD) with a frequency of 5 feeding factors, namely 1, 2, 3, 4 and 5 times a day. Treatment 1 (Feeding once a day), Treatment 2 (Feeding 2 times a day), Treatment 3 (Feeding 3 times a day), Treatment 4 (Feeding 4 times a day), Treatment 5 (Feeding 5 times a day). thus 15 units of experimental containers are needed with a container area of 59 x 37 x 17 cm3. Parameters observed included absolute weight growth, daily growth rate, feed efficiency, feed conversion, survival and quality water. The results showed that the frequency of feeding 3 times a day was the best treatment with absolute weight of 74 cm, absolute length of 2.10 cm, specific growth rate, 1.37%, feed efficiency 89.89%, feed conversion 1.11% , Survival rate 91.6%. Based on the results of the study the frequency of feeding 3 times a day is good to be applied to the growth of Mudcrabs (Scylla serrata).Keywords: Mullet Fish, Mudcrab, Absolute Weight Growth, Daily Growth Rate, Feed Efficiency, Feed Conversion, Survival
