A seafood vendor moving a giant swordfish to his stall at a market in Qingdao, Shandong province, China, last Saturday. The 4.1m-long swordfish, which weighed about 309.5kg, was caught in the Yellow Sea by Qingdao fishermen the day before, local media reported. A fisherman said the giant fish most likely swam into the net while chasing smaller fish. The fish was purchased for about 19,000 yuan (S$4,210), or around 60 yuan per kg. As swordfish are apex predators, the report also warned that the fish's meat could contain highly toxic methylmercury accumulated through the food chain.
