Abstract

Streams, dam and pool around the University of Riau is inhabited by many types of aquatic organisms, including freshwater loster (Cherax quadricarinatus). Freshwater lobster (Cherax quadricarinatus) is an alien species originated from Austalia. So far, the information obtained is only limited to type identification, while other information on the lobster is not yet known. To understand the feeding habit of freshwater lobster in the aquatic ecosystem, a research has been conducted in December-January 2017. There were three sampling areas, namely an earthen pool around the Rektorat Building (Station 1), the dam (Station 2) and the stream in the back of Marine Science Building (Station 3). Samplings were conducted everyday for a one month period. Lobster was captured using a scoop net and pit traps. Stomach content analysis was performed in the laboratory. Total number of lobster sampled was 40. Results shown that the main food of the lobster is detritus (IP>40%), the complementary food is fish remains, plant and phytoplankton (IP 4-40%).Keyword : Cherax quadricarinatus, Lobster, Index of preponderance, Stream, dam

Abstract Bunter lake is an oxbow lake that receive water from the Kampar River during the rainy season. This lake is inhabited by many fish species, however, the information about the type of fish in that area is limited. To understand the types of fish present in the Bunter lake, a study has been conducted in March to April 2019. Fish sampling were conducted every day for two weeks or there is no new species found. The fishes were captured using lures, gill nets and bamboo traps. Fish samples were then identified. Results shown that the caught fish consists of 3 orders, 16 families, 27 genera and 30 species. Among 30 species captured, 2 species were categorized as ornamental fish, 12 species were edible fishes and 16 species were ornamental-edible fishes. The water quality of the lake were as follows: temperature of 29oC-30oC, brightness of 40-65 cm, pH of 6, dissolved oxygen of 3.8-4.4 mg/L and carbondioxide 5.99-7.99 mg/L. Keywords: Oxbowlake, Rainy season, Ornamental fish, Edible fishes, Ornamental-edible fishes

Abstract

A study on the diversity of phytoplankton in the Solok Pulau Lake was conducted fromOctober–December 2015. This research aims to understand the diversity and abundance ofplankton in that area. There were three stations with 3 sampling points in each station. Sampleswere taken 3 times, once a week and they were analyzed in the Aquatic Productivity Laboratoryoh the Fisheries and Marine Science Faculty, Riau University.Result shown that the phytoplankton obtained were consist of 22 species, they werebelonged to of 6 classes, Bacillariophyceae (4 species), Chlorophyceae (10 species),Cyanophyceae (3 species), Dinophyceae (1 species), Euglenophyceae (3 species) danXantophyceae (1 species). The average of phytoplankton abundance was around 553 – 17.778cells/l. The most common phytoplankton was Isthmia sp. (28.978 cells/L, Bacillariophyceae).Diversity index (H’) was 2.47 – 3. 54 and dominancy index (C) was 0.11 – 0.21. General waterquality parameters are as follow: temperature: 28 – 30 °C, pH: 6, brightness: 38 – 70.5 cm, DO:6.7 – 7.6 mg/L, CO2: 9.8 – 12.7 mg/L, Nitrate: 0.02 – 0.04 mg/L and phosphate: 0.09 – 0.018mg/L. Based on phytoplankton abundance, the Solok Pulau Lake can be categorized asoligotrophic lake.Keywords : Phytoplankton Diversity, Bacillariophyceae, Solok Pulau Lake

Abstract               Seagrass beds have a variety of important functions in the seagrass ecosystem, including nursery areas, feeding grounds, and protected areas. To find out the fish that live in seagrass ecosystem, gillnet and bubu trap are used. The results of the identification of fish species that live in the seagrass ecosystems in the Mie Strait waters found 30 species of fish. From the calculation of species dominance. The type of seagrass in the Mie Strait seagrass is one type of seagrass. One type of seagrass is Enhalus accoroide. The water quality of the noodle strait waters is as follows: temperature 30-30.5 0C, brightness 2.5-3 m, pH 7-8, salinity 30-31 ppt, dissolved oxygen 6.1-6.5 mg / L Keywords : Types of fish, seagrass, strait of noodles

Abstract Paweh fish (Osteochilus hasselti C.V) is type of fish commonly inhabit the Bunter lake of Pangkalan Baru Village. However, information on reproductive biology of the fish is rare. To understand the biological aspects of this fish, a study was conducted.The fish was sampled once at two weeks for three months period, from August to October 2019. Parameters measured were sex ratio, gonad maturity level, Gonad Somatic Index (GSI), fecundity and egg diameter. Result shown that there was 52 males and 36 females (sex ratio 1.6: 1).In each sampling time there were male and female fishes in 1st, 2nd, 3rd and 4th maturity level. The Gonad Somatic Index (GSI) of male is around 3.30%-9.64% and female is around 6.04%-16.40%. The average fecundity of the female was 10.497-29.540 eggs. Egg diameter was around 0.5-1 mm. This result indicated that paweh fish were total spawner. Keywords: Sex ratio, gonad maturity level, gonad somatic index, fecundity, total spawner

Abstract

Coastal waters of Kundur Island is inhabit by marine organisms, including bivalve and gastropod. A research aims to determine the diversity of bivalve and gastropod in the coastal waters of the Kundur Island was conducted on Desember 2015-January 2016. Samples were taken at eight stations. Bivalve and gastropod indentification was based on Dharma (1992), Roberts et al. (1982), Morris (1966) and Abbott (1991). There were 10 species of bivalves and 28 species of gastropods present. The is highest bivalves and gastropods density were in the station 3, there was 6 organisms / m2 and the lowest was in the station 1 which was 3 organisms/ m2. Nerita funiculata shown the highest relative density (57%) while Ostrea lurida was the lowest (0.3%). The diversity index (H’) ranged from 1.28-2.81 (average), the evenness index (E) was 0.60-0.82. The dominant index (C) was 0.25-0.54, and it means that there was not dominant species. Based on data obtained, it can be concluded that the coastal waters of the Kundur Island is categorized as good.Keywords: Diversity, bivalve, gastropod, Kundur Island

Abstract

AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured  using a cast net, and a scoop net. There were  90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from    75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6;  DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish. Keywords: dark ring, growth ring pattern, sagita, catfish, polluted river

Abstract

The Sail River is the position in the center of Pekanbaru City and is affected because of the tides. Urban pollution is a significant giver to the Sail River of water quality degradation. The study was conducted between June and August to assess estimation pollution load Sail River and pollution levels using the Pollution Index method. Water quality parameters measured are physical (temperature, TSS) and chemical (pH, dissolved oxygen, BOD, COD, Pb, oil and grease, nitrate, as well as phosphate). The results showed that the Sail River was classified as lightly polluted at high tide and low tide. The pollution index value at high tide is higher with a range of 3.65-3.92 than at low tide (2.93-3.39). TSS is the highest pollution load of the Sail River that a value of 1079.83 mg/second at high tide and 1075.29 mg/second at low tide. The lowest pollution load is oil and grease at low tide (0.47 mg/second). Thus, it is necessary to control the level of water pollution in the Sail River.
