Abstract

ABSTRACTMicroplastic is plastic pieces sized ≤ 5 mm. The presence of microplastic in sediment negatively affectsthe environment as well as the benthic organism. As the costal area of the Naras Hilir Village facing the Indian Ocean, the microplastics carried by the water may be stranded in the beach. A research aims to understand the type and density of microplastic present in the coastal area of the village has been conducted on May-July 2019. There were 3 stations, in  the intertidal zone,namely in the low tide, middle and high tide areas. In each station, 15 plots (50 x 50 cm) were placed. Sediment from each plot was scrapped 5 cm depth and then were sieved and microplastics were collected manually. Results shown that there were 4 types of microplastics, namely film, fragmen, foam and fiber. The density of microplastic was 13.24 item/m3. The most common microplasticpresent was film (4.44 item/m3).The highest microplasticdensity was in the high tide (6.49 item/m3), but there was no difference in microplastic densities in all sampling areas (p = 0.097 > 0.05). Keywords:Plastic Waste,Intertidal Zone, Coastal Sediment, Marine Debris

Abstract

A laboratory scaled study aims to understand the ability of several fish speciesin reducing the amount of organic materials accumulated around floating cage fishculture has been conducted in the Fishery and Marine Science Faculty, RiauUniversity, Pekanbaru from August to December 2008. Fingerlings (15-20 cm SL) ofNile tilapia (Oreochromis niloticus) were caged (6 fishes/ cage) and each cage was keptin the 25 liter aquarium. Outside the cages, other fishes namely common carp(Cyprinus carpio), Nile tilapia (O. niloticus ) and Catfish (Clarias batracus) werereared, 3 fishes/ aquarium. As controls, Nile tilapia were kept in the cages and therewas no fish out side the floating cage. Fishes were feed on fish pellet, 40% of cagedfish body weight, once/ day. Feed remains that are flown to the outside of the cage.Sediment accumulated was removed once/week for a 3 weeks period, then they werefiltered and dried in the 40o oven and was weighed. The fishes, however, were weightin the 1st day and by the end of the experiment and the feed conversion rate wascalculated.Results indicated that the sediment in the nile-carp aquarium is 1,67 gram; thenile-nile is 1.79 gram, the nile-catfish is 1.54 gram and the control is 2.28 gram.While the FCR of the nile-carp is 1.47; nile-nile is 1.04; nile-catfish is 1.05 andcontrol is 3.16. So, it can be concluded that the presence of fishes outside the cagereduce the amount of sediment accumulated around the cage and increase theefficiency of feed given to the fish.

Abstract

A study on gut content analysis of fish species that are captured around thefloating caged fish culture area in the Koto Panjang Dam, Kampar, Riau Provincehas been conducted on June to September 2007. Aims of this research are tounderstand the type of fishes present around the cages, their food types and alsotheir role in reducing the amount of organic materials originated from fish cultureactivities. Fish samples were caught by scoop nets and fishing lines and gutcontent was analysis using a volumetric method. Results shown that 9 fishesspecies namely goramy (Osphronemus gouramy ), tambakan (Helostomatemincki) , kapiek (Puntius schwanefeldi), paweh (Osteochilus hasselti), commoncarp (Cyprinus carpio ), sipaku (Cyclocheleichthys apogon), nile tilapia(Oreochromis niloticus), ingir-ingir (Macrones nigriceps) and baung (Macronesnemurus) are able to eat pellets and fish remains that may present around thecages. Other species, such as belida (Notopterus notopterus), toman(Ophiocephalus micropeltes), gabus (Ophiocephalus striatus) and tapah (Wallagoleeri), prey on fish and shrimp only. The stomach of another fish species captured,namely katung fish (Pristolepis grotii), however, full of algae. Based on the dataof stomach content, it can be concluded that fish that have ability in eating pelletremains present around the cages may have important role in reducing the amountof organic materials originated from floating cages aquaculture.
