    GONAD MATURATION OF SEPAT RAWA (Trichogaster trichopterus Blkr) WITH DIFFERENT FEEDING TREATMENTS
    (2013-07-18) Noverzon, Rio; Sukendi, Sukendi; ; Nuraini, Nuraini
    The research was conducted from Februari to April 2013 in experimental ponds Fishery and Marine Science Faculty of Riau University. The aim of this research was to investigate suitable feed for the maturation of the gonads of sepat rawa (Trichogaster trichopterus Blkr) reared with different feeding treatment such as Gonad Maturity Level (TKG), gonad maturation index (IKG), fecundity, egg diameter and egg maturation. The research method used was Completely Randomized Design (CDR) with three treatments and three replications. The treatment in this study were P1 (Tubifex sp), P2 (Shrimp pellet), P3 (Shrimp pellet + Vitamin E). The result showed that good feed for the maturation of the gonads was shrimp pellets + Vitamin E, reared for 42 days and the total fish reached TKG IV 21 tails , index gonad somatic 10,59 %, fecundity of 6435 eggs, egg diameter 0.71 mm. The temperature range from 29 – 320 C, pH 6 – 8, dissolved oxygen 4.5 – 5,0 ppm.

    Morphological Characterization Of Baung Fish (Hemibagrus Nemurus) Aquatic Habitat On The Different Method Based Truss Morfometrics
    (2018-02-13) Aryani, Netti; Nuraini, Nuraini; Indra, Suharman
    Research morphometric characters of H. nemurus conducted in 2012 in the waters of Koto Panjang Reservoir Kampar Regency, the waters of Kampar River Langgam Village Kampar Regency and Kampar River Kampung Baru Village Pelalawan Regency Riau Province. The purpose of research is to analyze the morphometric characters, the main differentiating factor, determination of inter grouping of H. nemurus populations. Results showed that the average length of H. nemurus population standard Koto Panjang Reservoir Kampar Regency 281.33 ± 27.08 mm significantly different with populations Kampar river waters Langgam Village Kampar Regency 318.03 ± 32.07 mm and the water Kampar River Kampung Baru Village Pelalawan Regency 320.80 ± 32.03 mm. The main differentiator of 30 morphometric charac-ters are long dorsal truss2 (G2) and long dorsal truss3 (G3) with a value of 0.940 respectively. H. nemurus populations are geographically sepa-rated from each habitat and genetic distance H. nemurus populations in waters Langgam village closer with a population of Kampung Baru village.
