1996, the first New Zealand fishing boat entered the Ross Sea to fish, and Antarctic cod began to jump into the human table. Only a few years later, all countries in the world praised this delicious food. Intensive fishing has affected the ecology of the Ross Sea, and the number of cod has been greatly reduced. People of insight in the west have pushed forward the regulations to restrict fishing to protect species and the environment. Since 2002, the catch of Antarctic cod has been decreasing every year.
