Abstrack Ompok hypophthalmus is one of the caught fish commonly found in the Indragiri River, Lubuk Terentang Village. The purpose of this study was to determine the rate of growth and mortality of Ompok hypophthalmus. Fish sampling was carried out for 10 days in February and 10 days in March by using drift nets and nets. Data were analyzed by ELEFAN I method, FiSAT II software (FAO-ICLARM Fish Stock Assessment Tool). There were 109 fish caught. The results showed that the growth pattern of fish was negative allometric. Long frequency distribution ranges from 150 to 261 mm. The results of the Von Bertalanffy growth equation show that Lt = 260.40 (1-e-1,2(t+0.073)). This means the asymptote length (L∞) of the hypophthalmic is 260.40, the growth coefficient (K) 1.2 per year and the theoretical age (t0) of fish is equal to 0.073. The total mortality (Z) of fish is 1.88 per year. The estimated natural mortality (M) of fish is 1.09 per year and deaths due to capture (F) of 0.79 per year. The exploitation rate (E) of fish is 0.42 and shows this value is still below the optimum exploitation rate of 0.50.Keywords: Selais Fish, Ompok hypophthalmus, Growth Rate, Mortality, Indragiri River, Lubuk Terentang Village

ABSTRACTIndragiri River has high biological resources as necton, gastropods, plankton and the others. There are activities antropogenic can affect the distribution of Pilsbryochonca exillis. P. exillishas good ecological and economic potential. This study aimedto determine the distribution and density of P. exillis in the Indragiri river, Lubuk Terentang village, Kuantan Singingi Regency, Riau Province. Sampling used the plot method and hand sampling, a plot divided into 9 sub-plots (9x3m). The results shown that the distribution of P. exillisis uniform and clumped. The distribution based on Morishitaindexis about 0,47 to 1,06. The highest density found in Station I was 1,05 ind/m2 and the lowest was found in Station III was 0,22 ind/m2. It is also known that the distribution and density of P. exillis in Indragiri River Waters are not disturbed. Keywords: River Organisms, Distribution,Characteristic, Density and Gastropods

Abstract Raja Lake in Rengat City has various social, economic and ecological functions such as tourism and fishing. These various activities produce pollutants that will affect water quality. This study aims to determine the status of water quality in Raja Lake. The study was conducted in August 2021. Water samples were taken at 3 stations with 3 replications. The water quality parameters measured were temperature, TSS, TDS, pH, COD, BOD5, fat oil, sulfur, detergent and total coliform. The measurement results show that the COD are higher than the standards issued by the Indonesian government. Temperatures ranged from 29-31oC, pH 6, BOD5with a value of 2.2 – 3.4 mg/L, TSS 11 - 23 mg/L, TDS 46 - 87 mg/L, sulfur 0.0001 – 0.012 mg/ L, fat oil 106 - 188 µg/L, detergent 79 - 183 µg/L and total coliform 15-28 MPN/100 ml. Based on the data obtained, it can be concluded that Raja Lake is classified as moderately polluted (scores range from -4 to -8).

Abstract Malong fish (Muraenesox cinerus) is a demersal fish that has important economic value and provides large contribution in the number of fish catches in the Bengkalis Regency. The purpose of this research is to find out the growth and exploitation rate the fish in the Bengkalis waters. This research was conducted in May-July 2020 and fish samples were collected from the fish landing place located in the Meskom Village. Data were analysis by aELEFAN I method (Electronic Lenght Frequencys Assesment Tool) from the FISAT II (FAO-ICLARM Fish Stock Assesment Tool) software. Muraenesox cinerus captured were 82 samples consisted of 34 males and 48 females. The length frequency distribution of the female fish shown that the most common fish were around 149-161 cm TL, while that of the males were 142-153 cm TL. The length-weight relationship of male was negative allometric and female was negative allometric. The growth coefficient (K) of the male fish was 10/year while that of the female was 5.01/year, the infinitive length (L∞) of male was 201 cm and that of the female was 213 cm. The theoretical lifespan (t0) of male was -0.0086/year while that of the female was -0.0174/year. The Von Bertalanffy growth equation of the male was Lt=201(1-e-10(t+0.0086)) and that of the female was Lt=213(1-e-5.01(t+0.0174)). The estimated natural mortality (M) of the female was 2.94/year, the mortality due to catching activity (F) was 4.51/year. The suspected natural mortality (M) of the male was 4.70/year, the mortality due to catching activity (F) was 20.26/year. The exploitation rate (E) of the male was 81% and that of the female was 61% or already exceeds the optimum exploitation value limit of 50%.Keywords: Exploitation Rate, Growth Pattern, Long-Weight relationship, Mortality, Silver conger, Von Bertalanffy

ABSTRACTMarine debris is a type of pollutant that commonly found in the mangrove ecosystems. This spurpose of this study was to determine the composition and density of marine debris in the mangrove ecosystem in Pongkar Village. Sample was carried out in July - August 2020. The method used is the survey method. Sampling was carried out three times (once/2 weeks) at 3 observation stations, namely S1 (ecotourism area), S2 (natural mangrove forest) and S3 (port area and residential area). Marine debris was collected from 3 plots (10 x 10 m) placed along the transect line. The types of marine debris found in the mangrove ecosystem consist of plastic, glass, rubber, cloth, styrofoam, nets, cans, wood, steel and paper. Marine density based on the characteristics of debris are: megadebris (0.01 - 0.04 items/m2; 4.61 - 34.67 grams/m2), macrodebris (1.43 - 4.75 items/m2; 249.19 - 724.53 gram/m2), mesodebris (0.79 - 2.20 items/m2; 1.54 - 3.23 gram/m2). The most common marine debris found were plastics (69.27%) and styrofoams (15.65%).Keywords:Pongkar Village, Mangrove Area and Marine Debris

ABSTRAC Pariaman Regency coastal area is affected by current and tide from Indian Ocean that contribute the presence of microplastic in that area. To understand the microplastic types and density, a research has been conducted in May-July 2019. There were 3 sampling sites (Pantai Mangguang, Pantai Ampalu and Pantai Gandoriah) and there were 3 plots (50x50 cm) placed in each site. Sediment inside the plot was scrapped 5 cm depth. The sediment was then sieved (5 and 1 mm mesh size), dried and soaked in 35% NaCl. The floating microplastics were then collected and identified using a dissecting microscope. Results shown that there were 4 types of microplastic present, they were film, fragmen, fiber and foam. The most common microplastic found was film (1,360item/m3). The density of microplastic found in the sampling site ranges from 400 - 1,840 item/m3. In the intertidal zone, the highest density of microplastic was found in the highest tidal level (2000 item/m3). Keywords: Plastic Pollution, Intertidal Zone, Sediment, Film.
