Cormorant fishing on Lake Erhai, near Dali, Yunnan, China. Unlike other locations such as Gifu in Japan and Guilin in China, where fishing takes place at night, here the cormorants catch by day, mainly carp. Their necks are tied so that they cannot swalow the fish. The fisherman, Yang Yizhu, has 30 years experience, and still makes most of his living fishing in this traditional way.
