Sedimen tidak hanya berfungsi sebagai recervoir bagi kontaminan tetapi bisa juga sebagai sumber toksikan bagi organisme laut. Uji biologis sedimen merupakan salah satu tahap penting dalam penilaian kualitas lingkungan laut melalui informasi toksikan terhadap biota. Penelitian ini bertujuan mengkaji aspek toksisitas sedimen pesisir Cirebon terhadap abnormalitas larva kerang hijau, Penna viridis. Sampel sedimen diambil dari 11 stasiun pada bulan Februari 2010 dengan menggunakan Grab Smith McIntrye 0,05 m2. Larva kerang hijau dipaparkan terhadap overlying water ...

ABSTRACT
Contamination in Indonesian waters needs to be continuously monitored to prevent serious damage an ecosystem. Environmental monitoring involves not only contamination analyses in water; sediment and organisms but also application in ecotoxicological approach to detect contaminant effects to organism. Selection for bioindicator must consider many factors including abundance, easy to handling, taxonomy is well known, sensitivity and ecological relevance. Java merdeka (Oryzias avanicus meets that requirements and potentially to develop as bioindicator for environmental monitoring ...

ABSTRACT
Sediment bioassay requires a test organism which suitable with the test material, for example sediment. However, benthic phytoplankton as the organism has not been widely applied in Indonesia. Recently, bioassay test still uses phytoplankton which lives in water cplumn such as Chaetoceros gracilis, Tetraselmis sp., Isochrysis sp., or uses another test organism like ussel, sea urchin larvae and amphipod. In addition, Nitszchia sp. is one of culture collection at rResearch Centre for Oceanography so it ...
