China - A grossly overweight grouper has died at an aquarium in Beihai, a coastal city in south
China's Guangxi Zhuang Autonomous Region. Ample food and little movement made the fish, which was almost twice the size it should be, suffer from arteriosclerosis, a chronic disease in which thickening and hardening of the arterial walls resulted in impaired blood circulation, said Yang Chunyong, a breeding engineer at Beihai Sea World after a postmortem. The grouper was about 30cm long and weighed around 6kg (13 pounds) when it was introduced to the aquarium five years ago. Since then, it had eaten at least 10kg (22 pounds) of fish everyday and was now 150kg (330 pounds) and 1.6m (5.25ft)-long The aquarium has decided to reduce food quantities, give a more balanced diet and give more exercise to the other five five-year-old groupers, which all weigh over 100kg (220.5 pounds). |
