The U. S. research from the 1980s estimated a meal of 30 kilograms could make a one-tonshark continue living for more than six weeks. That made assumptions that large sharks could survive long periods without eating. However, a University of Tasmania-led study published this week in Scientific Reports found that 30kg was only enough for 12-15days. Researchers tagged (给……附上标签) a dozen great white sharks at Neptune Islands off South Australia and calculated their metabolic (新陈代谢的) rate based on swimming speeds. They worked out how much energy the sharks burned and how much food they required. “Their metabolic rate is faster than we assumed.” Jayson Semmens was the lead author on the study. He said, “They (U. S. researchers) picked a shark that probably wasn’t working very hard at the time when they did it . At the time it was a new study. They did some metabolic work similar to us but on one shark.” “The white sharks, which we tagged, are working pretty hard … they’re coming up to some pretty high speed to catch the seals.” he said, ”Their metabolic rate is much faster than what we had assumed. These animals are probably going to be feeding every day, rather than several weeks.” The research also sought to improve understanding of how sharks fit into the ocean ecosystem. “We don’t have a good handle on the population sizes of white sharks. We know that sharks in general are under pressure around the world from overfishing.” Semmens said, “Furthermor
