Marine police have seized this year's largest consignment of smuggled seafood and other goods bound for dining tables in Hong Kong. More than 4 tonnes of live fish, turtles, frogs and frozen large-mouth bass were found yesterday in dozens of boxes on a boat from Guangdong province, police said. Officers arrested three Hong Kong men and two mainlanders. Superintendent John Cameron of the marine police's small boat division said the haul, worth about HK$200,000, was smuggled from Zhuhai. He said it was the first such seizure of aquaculture products this year and that the consignment was likely for local consumption. Shortly after midnight on Thursday, the fishing boat was caught by marine police off Shek Pik, Lantau Island. A Hong Kong captain, 51, and two mainland crew, aged 27 and 30, were on board. The three claimed they were taking the goods to Nanao , Guangdong, but were forced to enter Hong Kong waters by poor weather. The boat was released but police monitored it. At about 3.20am, the vessel berthed at a Sam Ka Tsuen pier in Yau Tong and the crew started to load the goods on to a truck with the help of two Hong Kong men. Police arrested the five men and confiscated the goods. The seizure included 1,600kg of frogs, 50kg of bullfrogs, 560kg of soft-shell turtles, 820kg of eels, 360kg of catfish, 60kg of loach and 320kg of frozen largemouth bass. Senior Inspector Wong Chi-keung said police were still investigating whether the goods were for wholesale markets or restaurants in Hong Kong. The goods would be tested to ascertain whether they were fit for human consumption. Police said the Agriculture, Fisheries and Conservation Department would look into a possible cruelty-to-animals offence over the storage of soft-shell turtles. There were seven boxes of the turtles and each contained 40 to 50. Last night, the five men were being held. No charges had been laid.
