Abstract

ABSTRACT This research was conducted in November 2017 aimed to analyze the heavy metal concentrations in sediment and surface sea water and the relationship between them as well as to know the level of metal pollution in Kundur Island Coastal Waters, Riau Islands Province. The highest concentration of Cr in sea water was found at Station 3 (0.0598 mg/l), while in sediment was at Station 2 (30,1533 μg/g). The highest concentration of Cu in seawater was found at Station 1 (0.0296 mg/l), while in sediment was at Station 3 (1.7967μg/g). The highest concentration of Zn in seawater was found at Station 2 (0.0904 mg/l) whereas in sediment was at Station 2 (39,5050 μg/g). Simple linear regression analysis for Cr indicated that  when Crconcentration in sea water increases, itsconcentrations in sediments also increases. On the contrary, when Cu and Zn concentration in water increases, their concentrations in sediments decreases and vice versa. The concentrations of Cr, Cu and Zn in seawater have exceeded the threshold value, while in the sediments their concentrations were considered as having nonegative effect to the existing organisms in these waters. Keywords: Heavy Metal, Pollution, Kundur Island, Water, Sediment

Abstract

ABSTRACT Carrying capacity is defined as the ability of aquatic environment to support the life organism in that area. A study aimed to assess the aquatic carrying capacity based on chlorophyll-a for extensive fishing was conducted in the Tajwid Lake. The carrying capacity was determined based on primary productivity (chlorophyll-a content), which is indicating the existence of phytoplankton in the water. This research was conducted in March-April 2018 in the Tajwid Lake. There were 3 stations, namely Station 1 (inlet area), Station 2 (in the middle of lake) and Station 3 (outlet area).  Water quality parameters measured were temperature, transparency, pH, dissolved oxygen, CO2, nitrate, phosphate, and chlorophyll-a concentration. The concentration of chlorophyll-a indicates that the carrying capacity of the Tajwid lake for extensive fishing was 6.925 tons/year. Water quality parameters were as follows: transparency 47.0-54.7 cm, temperature 29.3-30.7oC, pH 5, dissolved oxygen  4.75-6.29 mg/L, CO2 17.32-22.64 mg/L, nitrate 0.0541-0.0820 mg/L, phosphate 0.1327-0.2798 mg/L, and concentration of chlorophyll-a  was 7.96 µg/L.

Abstract

ABSTRACT This research was conducted in March 2018 with the aim to determine the concentration of Pb, Cu and Zn, and their relation to the size of snail (Cerithidea montagnei) and to determine the safe limits of snail consumption, and to estimate the level of metal pollution in the waters of Air Hitam Strait. Sampling locations were determined by using purposive sampling and was conducted in areas with relatively different anthropogenic activities. Heavy metal concentration analysis was performed at the Marine Chemistry Laboratory, Faculty of Fisheries and Marine, Universitas Riau. The results showed that the metal content of Pb at station 1 was 1,128 μg/g and in station 2 that was 1,000 μg/g, Cu at station 1 was 45,480 μg/g and in station 2 was 69,756 μg/g while Zn at station 1 was 115,556 μg/g and at station 2 is 152,836 μg/g. A simple linear regression analysis between the size and the metal concentration of Pb in the snail showed a strong relationship, while Cu and Zn concentration showed a moderate relationship. The safe limit of snail consumption in the waters of Air Hitam Strait for Pb metal is 6.6789 kg/week, Cu is 17.0086 kg/week and Zn is 14.6055 kg/week. The MPI value forAir Hitam Strait is 20.19, which illustrates that the waters of the Strait is in the state of relatively polluted. Keywords: Pollution, Heavy Metal, KepulauanMeranti Regency

Abstract

AbstractBelontia hasselti is a typeof freshwater fish that inhabit swamp waters.Information on biological, including morphometric, meristic, and growth patterns of the fish is rare. To understand the morphometrical andmeristicalcharacteristics, and growth patterns of the fish, a research had been conducted from February to March 2018. There were 100 fishes (70.08-130.05 mm TL and 7.44-40.02 gr BW). There were 26 morphological characteristics measured and 11 meristical characteristics counted. The meristical characteristics were as follows: D. XVI-XVII, 10-13 P.10-12,   V.I, 4-6 A. XV-XVII, 11-13). The number of scale in the pre-dorsal fin was 22-24, in the cheek was 4-6, around the body was 32-42,  in the caudal peduncle was 14-16, above lateral line was 4.5-6.5 and under lateral line was 11.5-13.5). There were 5 morphometrical characteristic differences between male and female B.hasselti.They wereheight of the head,  space from aye to the dorsal fin, space from ventral fin to the anal fin, the height of dorsal and the height of anal.The length-weight relationship shown that the growth of male and female was allometric negative.Keywords:freshwater fish, allometric, morphological characteristic, meristic characteristic

Abstract

Abstract The carrying capacity is defined as the ability of aquatic environment to support the life of organism in that area. A study aimed to assess the aquatic carrying capacity for extensive fishing in the Tanjung Putus Lake, Buluh China Village, Kampar District, Riau. The carrying capacity was determined based on primary productivity using chlorophyll-a value, which is indicating the existence of phosphate in waters.This research was conducted March, 2018.There were 3 stations namely station 1 (inlet area), station 2 (in the middle of lake) and station 3 (outlet area). In each stations, there were 2 sampling sites, in the surface and in the middle of water column. Sampling was done three times, once a week. Water quality parameters measured weretransparency, temperature, pH, dissolved oxygen, phosphate and nitrate concentration. Results shown that chlorophyll-a: 6.98-7.52 µg/L, transparency: 85.17-96.5 cm, temperature: 30.2-31.8 oC, pH: 5, dissolved oxygen: 4.82-         6 mg/L, phosphate: 0.05-0.09 mg/L and nitrate: 0.05-0.06 mg/L. The concentration of chlorophyll-a indicates that the carrying capacity of the Tanjung Putus Lake for extensive fishing was 1,74 tons/year. Keyword: Oxbow lake, Extensive fishing, Phytoplankton, Water quality
