Abstract

This research was conducted in August and November 2013 in the province of Riau Strait Bengkalis. The method used in this study is a survey method . The purpose of this study was to determine the potential catches Terubuk ( Tenualosa macrura ) in Bengkalis waters. The results showed that the results of the survey of the Terubuk fish were caught fishing waters Bengkalis the month from August to November 2013. Retrieved Terubuk number and size of fish caught as many as 3554 head comprising 1082 males and 2472 Terubuk tail tail Terubuk females . Terubuk fish growth speed at the time a young age faster than when the fish is old. The rapid growth of the young - old fish occurs because the energy obtained from food are mostly used for growth. In older fish the energy obtained from food is no longer used for growth, but only used to maintain it self and replace the damaged cells.The rate of death arrest ( F ) during the study period is higher than the rate of natural mortality ( M ) , so that the total mortality rate ( Z ) during the periods of the study are determined by the rate of death arrest ( F ). Terubuk fish mortality rate during the study period due to factors at the time of capture by fishing for migratory fish spawning . Terubuk endangered fish caused by two main factors : first, the seizure at the time of entry into migratory fish Strait Bengkalis, secondly, the quality of the water into a fish alive Terubuk diminishing.Keywords : Potential , Terubuk Fish , Aquatic Bengkalis

Abstract

This study was conducted from Juni to November 2013 in The Barumun River and in the laboratory of the Fishery Biology, Fisheries and Marine Sciences Faculty, Riau University. It aims to determine the reproductive biology of the tenualosa ilisha. Sex ratio, gonad maturating level, gonado somatic index, eggs diameter, fecundity were observed visually and analyzed based on Cassei (in Effendie, 1979). While histological characteristics of the gonad was studied based on Effendie (1979).111 fishes were caught and results indicated that male and female ratio was 3,2 : 1 and it was not significantly different (X2 test). The age of maturity of males was achieved by 120 g (BW) and 160 mm (SL), while that of the female was 400 g (BW) and 270 mm (SL). The body weight may increase as the gonad maturation level increase. The range of gonado somatic index was 0,3–25,0 %. The range of eggs diameter in the 4th maturity stage was 0,2–0,9 mm in diameter. The fecundity of (number of eggs) fish with 285–495 mm (SL) and gonad weight was around 81.450–245.267 eggs. Results of histological study shown that the eggs and sperm in the gonad are on several maturity stages.Keyword : Tenualosa ilisha, Barumun river, Sex ratio, Gonadal Maturating Index, Fecundity

Abstract

This research was carried out in the lacustrine and transition zone of Koto Panjang Reservoir from October - December 2013. Objective of the present research was to find out the vertical profile of nitrate in this reservoir. The research used survey method, samples were taken horizontally in four stations and vertically in five sampling points. The parameters of water quality measured were nitrate, dissolved oxygen (DO), pH, transparancy, temperature and depth. In the lacustrine zone concentration of nitrate in the surface was 0,148 – 0,166 mg/l, in the 2 Secchi depth was 0,16 – 0,168 mg/l, in the 4 Secchi depth was 0,153 – 0,162 mg/l, in the 12 m depth was 0,158 – 0,166 mg/l and in the bottom was 0,17 – 0,192 mg/l. In the transition zone concentration of nitrate in the surface was 0,1525 – 0,155 mg/l, in the 2 Secchi depth was 0,157 – 0,158 mg/l, in the 4 Secchi depth was 0,158 – 0,175mg/l, and in the bottom was 0,176 – 0,185mg/l. The concentration of dissolved oxygen (DO) was in the range of 0,10 – 8,75 mg/l. The value of pH was in the range of 5,4 – 5,9. Transparancy was in the range of 83,8 – 105 cm. Temperature was in the range of 28 – 32,3 oC. Depth was in the range of 9,3 – 22,7 m. The vertical profile of nitrate in the lacustrine and transition zone Koto Panjang reservoir of the present reseach revealed that nitrate concentration in the transition zone was relatively lower than that of lacustrine in the surface layer of the water, but the pattern of vertical nitrate profile in each zone was similar in which it increased with increasing depth. The parameters of water quality were observed still sustained the aquatic organism life.Keywords: nitrate, the vertical profile, PLTA Koto Panjang Reservoir

Abstract

This research was conducted at December 2013 in the Lambur Luar, East Muara Sabak, East Tanjung Jabung, Jambi Province. The purpose of this study was to determine the efficiency of Trawl cod end. While the benefits are expected to provide useful information for writers, for readers, and for the people Lambur Luar, as well as an input to the fisher of Lambur Luar to modify fishing gear and Trawl cod end size so as to correspond to the number of catches expected. Efficiency of Trawl cod end is a principle which enables the achievement of the best comparison between total catches and volume of Trawl cod end. Efficiency values of Trawl cod end obtained from the division between total catches per operation with Trawl cod end volume and multiplied by 100 %. The trawl cod end of Lambur Luar is very inefficient, it can see from the result the values of trawl cod end efficency between 0,1-0,31. The average of trawl cod end efficiency is 0,15.Keywords : Efficiency, Trawl cod end, Total catches.

Abstract

The research was conducted from July to September 2013 in PLTA Koto PanjangReservoir Kampar Regency, Riau Province. This research aims to see the vertical profile ofdissolved oxygen in lacustrine and transition zone in the PLTA Koto Panjang reservoir, seethe depth is safe for the concentration of dissolved oxygen for aquaticlife organisms and todetermine the effect of oxygen on the KJA to lacustrine and transition zone . Water sampleswere collected from four station, namely station L1 and L2 in lacustrine zone, T1 and T2 intransition zone. In each station, vertikal sampling is determined based on transparancy namelyin the surface, 2 Secchi depth (3 meters), 4 secchi depth (6 meters), 12 meters and in thebottom. Sample was done three time and sampling interval three week. The water qualityparameters measured were dissolved oxygen, free carbon dioxide, pH, nitrate, phosphate,temperature, depth, transparency, and phytoplankton abundance.The result shown dissolved oxygen in the surface range 7,14 – 7,94 mg/L, 2 secchidepth 5,35 – 7,81 mg/L, 4 secchi depth 3,01 – 4,67 mg/L, 12 meters 0,68 – 2,33 mg/L and inthe bottom 0,14 – 1,37 mg/L. CO2 range 5,32 – 38,62 mg/L, pH 5,50 – 5,83, nitrate 0,24 –0,32 mg/L, 0,02 – 0,14 mg/L, temperature 27,67 – 32,33 0C, depth 9,1 – 23,9 m, transparancy86 – 111,67 cm, phytoplankton abundance range 54.004 – 83.469 cells/L. Based on theverikal profil of dissolved oxygen shown the concentration of dissolved oxygen decreaseswith increasing depth. In the lacustrine zone of dissolved oxygen concentration has anoksix at12 m.Keyword : Dissolved Oxygen, Vertical Profile, PLTA Koto Panjang Reservoir
