Abstract

ABSTRACT The research was conducted from 9 November until 30 December 2017 in Fish Breeding andHatchery Laboratory Faculty of Fisheries and Marine, University of Riau.  The aim of the research was to know the effect of density and Tubifex sp forms on the growth and survival rate of climbing perch larvae(Anabas testudineus Bloch).The method used in this research was the experimental method whereas the design used was a complete randomized design factorial with two factors namely first factor stocking density with two levels of each T2 (2 tail/liter), T4(4 tail/liter). While the second factor is the different Tubifex sp forms with three levels of fresh Tubifex sp (TS), frozen Tubifex sp (TB) and boiled chicken egg yolks enriched Tubifex sp (TK). To minimize the errors each treatment level was repeated 3 times. The best growth rate was obtained at the treatment T2TS (density 2 tail/liter with fresh form Tubifexfeed) with an absolute weight of 2,23 gr, absolute length of 3,98 cm, dayli growth rate of 12,68 %/day, and survival rate 100 %. The water quality condition were: water temperature 25,7-29 0C, pH 5,4-6,0and dissolved oxygen 5,1-6,0mg/l. Key word :Anabas testudineusBloch, density, Tubifex  sp form, and recirculation

Abstract

AbstractThis study was carried out to evaluate the combined effects of  four background tank color and two stocking density on growth and survival rate of stripped catfish Pangasius hyophthalmus  larvae reared with a water recirculation system.The fish larvae (0,002 g) were reared in aquarium with white, black,  Blueand clear backgoround at two stocking densities of 5 fish/L (75 fish/aquarium)and 10 fish/L ( 150 fish/aquarium). The inside walls and the bottom of each aqauarium were laminated with colored water resistant paper to achieve the background color tested (white, black and blue) while nonlaminated (clear) aquarium serves as a control. The larvae were fed on tubifex worms trice a day for 40 days rearing period. The best growth- weight, length and specifc growth rate  were obtained  for larvae reared at 5 fish /L stocking densities. While Survival rate of larvae was not significantly diferent with 96,3% for larvae stocked at 5/L and 95,75% for larvae stocke at 10/L respectively. The darker background color aquarium (black and blue)  significantly gave  better growth rates compared to those clearer ones (white and clear aquarium). The result seggested that Pangasius hypophthalmus larvae shiud be reared at 10 fish/L aquarium with black background. Keywords : Background colour, Stocking denstity,Siammese Catfish Larvae,
