According to the article, in Eastern Europe zebra mussel is native freshwater shellfish now reach to North America. This migration cannot stop causes harm to the freshwater fish population in North America. Whereas, the lecturer contradict the author view about the migration. He says that zebra mussel serious harm to other freshwater fish and this problem now easily solve to prevent the migration of the zebra mussel. In past, invasion cannot be stopped because of lack of knowledge but now it is can be possible to control the migration.
Firstly, the passage implies that zebra mussel spread by human transportation because of mussel fasten to ship bottom and easily survive by ballast water which is required for ship balance. In contrast with this, the speaker explains that ship needs to balance its cargo. when ship come to the ocean they can pour out water in an ocean so, ultimately zebra mussel kills because they exchange the ship water to salty ocean water.
Secondly, the article emphasizes that mussel dominant because of no any predators. On the contrary with this, the lecturer mentions that in begin mussel were dominant but after local birds change their food habit and eat the mussel.
Thirdly, the author states that decline the overall fish because mussel and plankton eater mussel compete with other fish for food. On the other hand, the professor points out that overall fish population not decline but surging because of mussel eat plankton and release the nutrients which are eat by the bottom of the sea fish.
