This study was coducted to describe the distribution and appearance pattern of macrobenthos in Kamak Bay, the southern coastal of Korea. Sampling was perfound seasonally using Van Veen grab(0.1㎡) from April 2001 to December 2001. A total of 22 macrobenthic species occured: Bivalvia accounted for 12 species(55%), and Mollusca 5 species(23%). The mean density of macrobenthos was 153.9ind./㎡, a major dominant species were a Bivalvia, Paphia undulata(28.3ind./㎡), and a Cirripedia, Chthamalus challengeri(5ind./㎡), which frequency occur in the costral area. These species showed very low density at station 1 in the Kamak Bay.

These days, the underwater excavation and the piling work have been commonly used to reclaim land and to build a breakwater. As the piling work generates high underwater sound pressure in all direction, various kinds of marine organisms are largely affected even if they live a long distance from the piling work. Therefore, this paper describes the relationship between the behavior of abalone(Haliotis discus hannai) of 50cm long and the environmental noise level with vibration due to the piling work. We have separated the research into two parts. The one is continuance impact, the other is intermittent impact. The following are the results obtained from the present investigation: Comparing 0.5cm/sec vibration with 50dB noise and 0.9cm/sec vibration with 60dB, the previous one show a faster reaction speed than the later one. Futhermore the later one showed that pulling up on their shell, in order to avoid the epidemic, moving around, small organisms are included to hide under big organisms, alerting posture. However we couldn't find a consistent standard in our research.
