Abstract

AbstractMystus nigriceps is a  fish that in habit the Tapung River. To understand the morphometrical and meristical characteristics and growth pattern of this fish, a research had been conducted from April to May 2018. There were 100 fishes (99.68-190.6 mm SL and 4.92-49.32 gr BW) were captured. There were 30 characteristics measured and 9 meristical characteristics counted. Results shown that there were 5 morphometrical characteristic differences between male and female. The head height, eye diameter, anal fin base, anal fin height and anal fin base length of the male are longer than those of the female. There were 2 meristical characteristic differences between male and female fish.  There was a white spot in the male’s fish tail and the shape of the male genital papila is pointed, while that of the female is blunt. The meristical characteristic of the fish were as follow: D.I.5-7; P.I-II.8-22; A.5-9; V.5-10.1; C.16-23.Mystus nigriceps do not have any scale,  but it has 4 pairs of barbels, 2 pairs in the  maxilla  and 2 pairs in the mandible.The length-weight relationship shown that the growth of male and female was similiar, it was negative allometric with  b=2.59in male and b=2.31in female. Keywords: Catfish, Morphological characteristics, Meristicalcharacteristic, growth pattern

Abstract

ABSTRACT The aim of this study was to obtain the best dose of Rhizophora apiculata leaf extract added to the feed to prevent Motile Aeromonas Septicemia (MAS) as seen from the differentiation of leukocytes of siam jambal fish (Pangasius hypophthalmus). The method used is the experimental method with Completely Randomized Design (CRD), one factor with 5 levels of treatment and three replications. Kn: Negative control (feeding without being given R. apiculata leaf extract and without being challenged with A. hydrophila bacteria), Kp: Positive control (feeding without being given R. apiculata leaf extract and tested challenged with A. hydrophila bacteria), P1: Feed containing R. apiculata leaf extract at a dose of 1.5 mg/kg of feed, P2: Dose of 1.6 mg/kg of feed, P3: Dose of 1.7 mg/kg of feed. Siam Jambal fish (P. hypophthalmus) in size 8-10 cm are kept in an aquarium measuring 40×30×30cm with a stocking densities of 10 tail/aquarium, feeding as much as 10% of the body weight of fish and feeding three times a day. Taking the blood of the tested fishes was done 3 times, namely at the beginning of maintenance, after 30 days of maintenance and 14 days after the test challenged with A. hydrophila. The results of research show that P3 (Feed containing R. apiculata leaf extract with a dose of 1.7mg/kg of feed) was the best treatment with a total value of Leukocytes 11.72×104 cells/mm3, Lymphocytes 83.33%, Monocytes 8.67%, Neutrophils 8.00%, Phagocytic Activity 36.33%, and Survival Rate 80%. It can be concluded that feeding containing R. apiculata leaf extract can prevent Motile Aeromonas Septicemia (MAS) disease A. hydrophila and can increase the non-specific immune response of siam jambal fish. Keywords:Leukocyte,Pangasius hypopthalmus,Rhizophora apiculata, Aeromonas hydrophila

Abstract

ABSTRACTPopulation of Oxyeleotris marmorata in the Toba Lake, Sumatera Utara Province is relatively high and it  indicates that the lake environment is suitable for the life of the fish. To understand the biological aspects, a study has been carried out from May to June 2019. The fish was captured around the fish culture area. There were 26 morphological characters measured. The number of fish captures was 64 (19.1-35.1 cm PT and 79-594 gr BB). There were 7 morphometricl characteristic differences in female and male O. marmorata. In female, the distance between the mouth to the pectoral fin and the length of base pectoral fin is shorter than that of the male.  The length-weight relationship in O. marmorata was negatively allometric ( b  was 2.818 in female and 2.69 in male). Keywords:    Culture Area, Allometric Negative, Isometric, Morphological Characteristics

Abstract

ABSTRACT                This studywas conducted from May-August 2017 at the Laboratory of Hatchery and Fish Breeding, Marine and Fisheries Faculty University of Riau, Pekanbaru. The objective of this research was to evaluate the intergeneric hybridization between Common carp (Cyprinus carpio L) and Comet goldfish (Carassius auratus). Percentage of Fertilization, hatching, growth, survival in seven days (SR-7), survival rate in thirty days (SR-30),heterosis value, and to know the morphometric and meristic characteristics of hybridized seeds. The method was an experimental method with a Completely Randomized Design (CRD), one factor three times repetition. Spawning is induced breeding using ovaprim hormone with a dose of 0.5 ml/kg. The cross was done by fertilizing the Common carp eggs with Comet goldfish sperm and otherwise the comet fishgold egg is fertilized with Common carp sperm.            The results showed thathybridization was successfully. Heterosis of hybrid results positive to SR-7 parameter while the other parameters are negative. The hybrid ♀Cg × ♂Cc results have an advantage to FR, HR and SR values while the ♀Cc × ♂Cg hybrid results excel to absolute weight and length growth parameters.In general, hybrid seeds tend towards the common carp at a ratio of body width, head width, and head length to total length, while towards comet goldfish the character of height to total length compared. Keywords: intergeneric hybridization, growth, morphometric, common carp, comet goldfish

Abstract

Abstract Biosurfactants are surfactant compounds produced by microorganisms, and have the ability to reduce surface tension, and can break oil. This study aims to obtain biosurfactant producing bacteria from the pond contact ponds of the palm oil industry WWTP in PT. Sawit Asahan Indah, Ujung Batu, Rokan Hulu Regency. This research was conducted in March-May 2019. First, samples were enriched and diluted with BHI media for 24 hours. Then bacteria are identified by biochemical methods and 18S rDNA. The results revealed that the total number of colonies was 8.7 x 106 Cfu / ml. Morphological and biochemical characteristics obtained 3 types of bacteria, namely Proteus vulgaris, Proteus mirabillis, and Escherichia coli. Two of them are biosurfactant bacteria with the Proteus vulgaris emulsification index 58.3%, and Proteus mirabillis 61.6%. Keywords: Biosurfactant, Proteus vulgaris, Proteus mirabilis, Emulsification Index, 18S rDNA, Biodegradation

Abstract

AbstractRawa Mekar Jaya village is a mangrove conservation forest area. However anthropogenic activities conducted in that area damage the mangrove and thus negatively affects crabs living in that area. A research aims to identify  crab species and its density  was conducted in July 2019. There were 3 stations, with 3 plots/station and 5 sub plots/plot. In each sub plot, the crab were collected by hand. There were 5 crab species present, namely Periseserma sp, Uca vocans, Uca dussumieri, Uca rosea and Uca coarctata. The density of crab ranges from 5.8 - 15.6 organisms/m2.  The water quality were as follows: temperature  28 – 29 °C; pH  6 -7; dissolved oxygen  4.18 - 5.04 mg/L and salinity  14 - 16‰. The correlation coefficient (r) of mangrove and crab densities was 0.951, indicates a positive correlation.Keyword: Periseserma sp, Rhizophora appiculata, mangrove forest ,Uca sp

Abstract

AbstractThis research was conducted in March 2019 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine Science Faculty Riau University. Pekanbaru. The purpose of this study was to determine the best photoperiod in increasing the growth rate and biomass production of Chlorella sp. with a photobioreactor system with LED lights (Light Emitting Diode). The method used in this research was experimental using Completely Random Design (CRD) one factor with four treatments and repeated three times. The treatments used was P1 (24 bright - 0 dark), P2 (20 bright - 04 dark), P3 (16 bright - 08 dark), P4 (12 bright - 12 dark). Cultivation was carried out for ten days, using Dahril Fertilizer Solution. The results showed that the treatment of the dark cycle and the light cycle affected the population density and specific growth rate. Lighting 16 hours Bright - 08 hours Dark gave the best results with a cell density of 643.33 x 104 cells / ml and a specific growth rate of 0.1966 / day with peak growth occurring on the day eight. Water quality parameters during the study were optimal for the growth of Chlorella sp.with a water temperature of 29-33 0C, pH 7-8.9 and dissolved oxygen 8-8.5 mg / l. Keywords: Photopriode, Photobioreactors, Chlorella sp.
