|Title:||Effect of bottom trawling on the health of macro benthic community: a graphical technique approach|
|Abstract:||An attempt was made to study the health assessment of marine environment through graphical technique. Experimental trawling was carried out with the help of a commercial trawler during the study period of one year from January to December 2009. Maximum density of benthic organisms was recorded at 25m & 35m depth. Samples of ‘before and after’ trawling to ascertain whether, they are subjected to any form of disturbances or not, and the results are shown graphically. In these plots, it clearly revealed that the trend observed in ABC plots were on positive side, indicating undisturbed nature of benthic macro fauna. The values on the negative side indicating moderately disturbed. Cluster and MDS also group forming before and after trawling in both the regions.|
