ABSTRACTvuji.pujiono@yahoo.comThis research was conducted on Agustus 2014, which is held in the Laboratory Fishing Gear Materials, The Faculty of Fisheries and Marine Sciences, University of Riau. The purpose of this study was to determine the performance of stow nets fishing gear in the water, therefore it can infer the ideal flow velocity for this fishing gear. This study used an experimental method to determine the performance of stow nets fishing gear which is tested in the flume tank by using an impeller rotation speed was 5-50 Hz and the flow velocity was 2.7-246.1 cm/sec. The results were obtained that flow velocity made the effect on the position, the movement and the shift of stow nets fishing gear too. The ideal flow velocity for stow nets fishing gear was 44.3 cm /sec, while the flow velocity was 2.7 cm /sec it made the mouth of filter nets fishing gear started to open in the flume tank on the right time.Keyword : Flow velocity, performance, stow nets, flume tank.

ABSTRACTPrimadi.heri@yahoo.comThe purpose of this study was to find the right position of fishing gear. If the goal was reached, this study is expected to provide benefits for fishermen in the field of arrest. The comparison of two arm and four arm straps were to determined the position of fishing gear on surface water. According to the period of fishing gear, the shift of fishing gear, the experimental results showed that the gear four arm straps on 49.6 cm / sec flow velocity, it can be said that fishing gear is better than two more stout rope arm movements.Keywords : Flow velocity, fishing gear performance, fishing gear

Abstract

ABSTRACTThe research was conducted on September to October 2014. The study aims were to determine the abundance, size distribution and distribution pattern of mangrove snail (T. telescopium) in the Darul Aman Coastal Bengkalis Regency. The method used was a survey method. Samples of snail population and sediment were collected by a single visit during low tide. Location of study was divided into 3 stations. Station I have grow rare mangrove, residential community and coastal abrasion, station II have dense and closely mangrove, station III have close with river estuary, rarely struck high tide because higher dan mangrove grow rarely than. The sample analysis carried out in Marine Biologi Laboratory of Fishery and Marine Science Faculty of Riau University.The results of the study show that the highest abundance of snail was at the station III (2,05 ind/m2) and the lowest was at the station I (0,6 ind/m2). The most dominant of size distribution is 81 – 90 mm. Distribution pattern in this area is uniform with Id between 0,88 – 0,98.Keywords: Telescopium telescopium. abundance. distribution.

Abstract

AbstractIn floating cage fish culture activities, degradation of feed remain and fish feces willaffect the abundance of phytoplankton content in the surrounding area. A research aims tounderstand the difference of phytoplankton abundance in the water from the cage area and fromthe area that has no cage has been done from June – August 2014. In the Koto Panjang Dam,the floating cage fish culture is in the DAM site. Samplings were conducted 4 times, once/2weeks. There were 3 stations, namely 200 m upstream of the cage area (S1), in the cage area (S2)and 200 m downstream of the cage area (S3). In each station, water samples were collected from3 different depth, surface; 2 secchi and 4 secchi depths. Parameters measured were pH,phosphate, nitrate, free carbon dioxide, dissolved oxygen, transparancy, temperature and depth.Results shown the abundance of phytoplankton in the S1 was 1,068 – 8,226 cells/L ; in the S2was 500 – 3,720 cell/L; and in the S3 was 777 – 5,100 cells/L. The highest abundance ofPhytoplankton was in S1, while the lowest was in the cage area (S2). Phytoplankton abundancein the cage area was different compare to the area with no cage. Phytoplankton abundanceindicates that the DAM site area of the Koto Panjang can be classified as mesotrophic, especiallyin the area around the cage. Other water quality parameter measured were temperature: 29 oC –31oC; transparancy 1,98 m – 2,55 m; depth: 27 m – 40 m; pH: 5, free carbon dioxide: 4,49mg/L- 11,48 mg/L; dissolved oxygen: 3,28 – 7,17 mg/L; nitrate: 0,02 – 0,28 mg/L; phosphate :0,03 – 0,35 mg/L. the values of water quality parameters indicate that the water quality in theDAM site of the Koto Panjang is good and might be able to support the life of aquatic organismsin that area.Keywords: Phytoplankton, cage fish culture, Koto Panjang DAM

AbstractIn floating cage fish culture activities, degradation of feed remain and fish feces willincrease the Dissolved Oxygen content in the surrounding area. A research aims to understandthe Dissolved Oxygen concentration in the water from the cage area and from the area that hasno cage has been done from July - November 2014. In the Koto Panjang Dam, the floating cagefish culture is in the DAM site. Samplings were conducted 4 times, once/ 2 weeks. In There were3 stations, namely 200 m upstream nof the cage area (S1), in the cage area (S2) and 200 mdownstream of the cage area (S3). each station, water samples were collected from 3 differentdepth, surface; 2 secchi and 4 secchi depths. Parameters measured were dissolved oxygenconcentration, phytoplankton, free carbon dioxide, nitrate, phosphate, temperature, pH,transparancy, and depth. Result shown the concentration of Dissolved Oxygen in the S1 was 4,52mg/L – 7,17 mg/L; in the S2 was 3,28 mg/L – 6,57 mg/L; and in the S3 4,00 mg/L – 6,87 mg/L.The highest concentration of the Dissolved Oxygen was in the upstream (S1) while the lowestwas in S2. Other water quality parameter measured were phytoplankton: 500 cells/L – 8,226cells/L; free carbon dioxide: 4,49 mg/L - 11,48 mg/L; temperature: 30,6oC – 31oC; pH: 5;transparancy 1,98 m – 2,55 m; depth: 27 m – 40 m.
