Abstract

The research on the Comparisson between natural spawning and artificial spawning in gold fish oranda (Carassius auratus) was conducted in February 2014 in the Fish Hatchery and Breeding Laboratory of the Faculty of Fisheries and Marine Sciences, University of Riau. The research was to compare the result between natural spawning and artificial substrate with result artificial spawning using injection with ovaprim 0,5 ml/kg body weight females; 0,2 ml/kg body weight males in gold fish oranda (Carassius auratus). The container used in this study was 6 unit fiber size 100x60x50 cm2 The method used is an experimental method or direct observation and than process spawning one unit sampel don’t in simultaneously because different maturity level gold fish oranda.The results treatment showed that is natural spawning better than artificial spawning in terms of index ovisomatic 12,2 % (IOS); fertilized rate 86,8 % (FR), hatching rate 91,1 % (HR), survival rate of 10 days old fry 97,9 % (SR).Keywords: Spawning, substrat, gold fish oranda (Carassius auratus)

Abstract

This research was conducted from January-February 2014 in Sungai Alam Village,Bengkalis Sub District, Bengkalis Regency, Riau Province. The aim of research is tounderstand the relationship between mangrove density with abundance of bivalva.The result showed that 7 species of mangrove were found: Avicennia alba,Sonneratia alba, Rhizopora apiculata, R. mucronata, R. stylosa, Lumnitzera racemosa,Xylocarpus granatum. Density of mangrove between 2.834-4.233 trees/Ha. In eachstation, there were 2 kinds of bivalva such as Polymesoda expansa and Pharus sp. Theabundance of bivalva between 834 – 2.000 organism/Ha. The highest abundance wasobtained in the 3rd stasion (2000 organism/Ha), while the lowest was obtained in the 1ststation (834 organism/Ha). To found out relation between mangrove density and bivalvaabundance, the data were analized by using simple linier regretion. The regression line testbetween mangrove density with abundance of bivalva showed the equation Y= 272,3 +0,194 X with determine coefisien (R2) is 0,266 or 26,6 %.Keywords : Mangrove density, bivalva abundance, Sungai Alam, Bengkalis, Riau

Abstract

This research was conducted from January to February 2014 in the Air Hitam River,the city of Pekanbaru. This research aims to determine the condition of the Air Hitam Riverwater quality in terms of some aspects of physics, chemistry and biology macrozoobenthosorganisms. . There were 4 stations and 3 sampling points in each station. Water samples weretaken 3 times, once/ week. Water quality parameters measured were temperature, turbidity,current speed, total suspended solid, DO, pH, BOD and COD. While macrozoobenthos dataanalysis using the FBI index (Family Biotic Index).The results show that there are 9 classes / order, namely Gastropod (5 families),Trichoptera (2 families), Diptera (2 families), Ephemeroptera (1 family), Coleoptera (1family), Polydesmida, nematodes, Hydracarina and Oligochaeta. Water quality parametersare as follows: Temperature: 27.67-29.33 0C, turbidity: 9-17.56 NTU, current speed: 6-35cm/s, total suspended solid: 4.67-7.78 mg/l, DO: 4.96 -6.73 mg/l, COD: 22.40-38.40 mg/l,BOD5: 1.40-4.42 mg/l and pH: 5. Based on the Family Biotic Index macrozoobenthos, it canbe concluded that the level of water pollution in the Air Hitam River ranged from 5.31(polluted enough) to 6.93 (very much polluted). Based Storet Index, it can be concluded thatthe level of water pollution in the Air Hitam River is being polluted.Keywords : Air Hitam River, Water Quality, Family Biotic Index macrozoobenthos.

Abstract

A study aims to understand the community structure of mangrove that grow in the SungaiAlam village, Riau has been conducted from January to February 2014. Sampling was doneusing a line plot sampling method. Mangrove in the sampling sites were divided in to seedling,sapling, poles and trees. Mangroves were identified based on Rusila at al (2006), Bengen (2001)and Saparinto (2007). While data were analized following English, Wilkinson, and Baker (1994).Results shown that there were 10 mangrove types (8 families) present in the samplingarea they were Avicennia alba, Sonneratia alba, Acanthus ilicifolius, Acrostichum speciosum,Rhizophora mucronata, Rhizophora stylosa, Rhizophora apiculata, Nypa fruticans, Lumnitzeraracemosa and Xylocarpus granatum. The dominant species in the research area is Rhizophoraspp. Mangrove distribution on this research influenched by sediment types. Mangrove vegetationdominated by Avicennia spp. and Sonneratia spp. in the deep muddy area. While in the shallowmuddy area, it was dominated by Rhizophora spp. In the dry area Xylocarpus spp., Rhizophoraspp., and Nypa spp. were dominant. Shannon and Winner index of the mangrove ranged from0,66-1,92 and dominancy index (C) ranged from 0,36-0,1. Temperature ranged 28-30oC, land pH6, water pH ranged 6-7, and salinity ranged 21-22o/oo.Keyword : Mangrove, Community structure, Sungai Alam Village

Abstract

The study aims to understand morphological and meristical characteristics, relative growth and condition factor of Anabas testudineus living in Channel of oil Palm Plantation Left Tapung River Bencah Kelubi Village Tapung Kiri Subdistrict Riau Province. The study has been conducted on Januari to Maret 2014. The study used survey methods.Sampling was done five times in three month. Theresults shownthere were 125fishes (60-162 mm TL and 3-92 gr) which collected and measured. There are seven characters that will be calculated meristic and 27 morphometric characters that will be measured in this study. Meristical characteristics of fins were as follows D.XVII-XIX,7-9, P.13-15, V.1.5, A.IX-X,9-11, C.16-20. Twenty seven morphological characteristics were measured and to understand the growth pattern, each character length was compared with Total Length (TL) and was reflected as percent of the TL.The relative growth patterns of the morphological characteristic measured is the characteristic growing faster than that of the TL. Lenght-weight relationship shown that A. testudineus male growing isometric andA. testudineus female allometric positive (male b=2,837, and female 3,156).The water quality shown temperature 28 – 300C, pH 6-7, DO 0,9 – 2,3 mg/L, CO2 18,2-20,9 mg/L, transparency 5-7cm, depth 15-20 cm and all water quality still support the life of fish.Key words : Anabas testudineus, Channel of Oil Palm Plantation Left Tapung River, morphological characteristic, meristical characteristic

Abstract

Anabas testudineus is freshwater fish that commonly inhabit streams, rivers and canals in Riau. This fish is relatively cheap protein sources for people. However, information on biological aspects of this fish is limited. To understand the stomach content analysis of this fish, a study has been conducted from January – March 2014. The fish was sampled in the irrigation canals of the palm plantation area, using fish trap and line fishing. Stomach content of the fish was analyzed to calculate the Preponderance Index (PI).Total, there were 106 fishes captured, but 31 of them had empty stomach and could not be used for stomach content analysis. The number of fish analysed was 69. Results shown that the main food of A. testudineus was phytoplankton, namely Chlorophyceae (PI 89.00%), Bacillariophyceae (PI 4.42%) and Cyanophyceae (PI 5.36%). The most common Chlorophyceae present in the stomach was Ulotrix sp (PI 87.6%). Zooplankton was rare and the there was only remains of Crustacean (PI 1.22%) present in the stomach. Based of data obtained, it can be concluded that main food of A.testudineus is phytoplankton and the fish can be categorized as plankton feeder.Keyword : Anabas testudineus, Canal, Stomach Content Analysis, Index of Preponderance
