For investigating the causes of this death, pathological anatomy was carried out on February 21, 2002 on site, and age determination and other histological pathology analyses were carried out in laboratory later. This specimen was 1.92 m long, and weighted 78 kg. The age was estimated as 1.5 years as an infancy individual. The body shape looked normal, except some skin was off because of decomposing. One fish was found in the stomach. No other fatal pathological changes were found in respiratory, digestive, reproductive and other systems. But, several bloody areas were found underneath the skin, and especially on the surface of the brain. Based on the results above, it is considered that this dolphin was killed by explosion for cleaning up the navigation channel that happened in the area several days before the specimen was found. For protecting the dolphins in this area, some conservation measures are proposed.展开更多
