Abstract

AbstractFeatherback fish (Notopterus notopterus) is a type of freshwater fish that inhabit the Sail River. Pollutant that may contain heavy metals may contaminate the fish living in that area. Information on the content of  Cr and Cu in the fish living in that area is rare. To understand the Cr and Cu content in the liver, kidney and bone of the fish, a research had been conducted on December 2017 to January 2018. The fish captured was categorized into 3 groups, namely small (12.7-20.2 cm), medium (20.3-27.7 cm) and large (> 27.8 cm) sizes. Results shown that there were 35 fishes caught. The Cr and Cu content in the liver as well as the kidney increased as the fish growing. The Cr content was39.455 to 95.62 mg/kg in the liver and  34.025  to 65.29 mg/kg in the kidney, while the Cu content was 6.635 to 14.265 mg/kg in the kidney and 5.085 to 7 mg/kg in the liver. In contrast, the Cr and Cu content in the bone decreased as the fish growing, there was 76.79 to 20.31 mg/kg of Cr and 15.825 to 6.59 mg/kg of Cu content in the bone. Keywords     : freshwater fish, polluted river, heavy metal content, contaminated fish

Abstract

AbstractHampalamacrolepidota is a carnivorous  fish that inhabit the Kampar Kiri River, Mentulik Village. In the Kampar Kiri River there is waste from illegal gold mining, domestic waste, and floating cage aquaculture activities that pollute the water. The pollution may negatively affects small aquatic organisms that represent as prey for H. macrolepidota.To understand the type of food consumed by H. macrolepidota, a study has been conducted from  February to April 2018. Sampling was conducted 4 times, once/ 2 weeks for a two months period. There were 52 fishes captured, 19 fishes had full stomach and the others had empty stomach. Fish stomach was dissected, and each type of stomach contents was identified and weighed.Results shown that the content of the fish stomach consists of fish, leaves, and insect remains. The main food of H. macrolepidota is fish (Preponderance Index 90%).Keyword:Cyprinidae, Feeding Habit, Index of Preponderance, Carnivore fish.

Abstract

ABSTRACTSeagrasses are plants adapted to live fully in the marine environment. Seagrass plays an important role in coastal areas due to critical habitat for many kinds of marine animals such as fish, mollusks, crustaceans, echinoderms. This study was conducted from March 2018- May 2018 at the Seagrass Beach Conservation Area of Trikora Regency of Bintan Riau Island which aims to know: the density of each seagrass species and the change of seagrass area based on the mapping in 2006-2018. Sampling is done at three stations, namely Station I residential zone, Station II natural seagrass zone and Station III zone tourist resort. Sampling and measurement of water quality was done by using quadratic transect. The results obtained 8 (eight) seagrass species that was of Cymodoceaserrulata, Enhalusacoroide, Halodulepinifolia, Haloduleuninervis, Halophilaovalis, Syringodiumisotifolium, Thalassiahemprichii, Thalassodendronciliatum. The highest seagrass density obtained at Station II is 487.11 tegakan/m2 in the low seagrass areas. Referring to the criterion of seagrass density according to Braun-Blanquet that seagrass with density> 175 is very tight. The result of the change of seagrass area in 2006-2018 happened addition area of 122 ha, thus there is influence from TRIMANDES (activityTrikoraSeagrass Management Demonstration Site)onseagrass community.Keywords: Seagrass, Density, Area, Trikora
