The reading and the lecture are both about the invasion of a freshwater shellfish named zebra mussels to North America. While the author of the reading argues that their invasion cannot be stopped and cause a serious threat and damage to freshwater fish in North America, the professor disputes this claim. He states that the zebra mussel population can be controlled and should not be considered a severe threat. The lecturer casts doubt on the point made in the reading by providing three controversial reasons.
In the reading, the writer begins by saying that the zebra mussel invasion in the past indicates that their attack could be unstoppable. In the past, the mussels were carried by the ballast water of ships traveling from Europe to North America. However, the professor disagrees with this idea. He asserts that this phenomenon happened in the past because people did not have enough knowledge about controlling the population of zebra mussels. Also, there are some effective ways to prevent zebra mussel's from being transported by ships. The ships can empty their ballast water in the ocean instead of freshwater of North America; as a result, salt water kills them, and they do not get the chance to enter fresh water.
Furthermore, according to the reading passage, zebra mussels usually become a dominant species in a new environment since they do not have any predators. On the other hand, the professor points out that this is true that at the beginning, they have no predators, but sooner or later, local birds will change their eating habits and prey on them. Because the birds can eat many of them, their population will be controlled.
Finally, the author believes that because mussels eat plankton, they may pose a decline in the total fish population in the new habitats. Not surprisingly, the professor refutes this assertion by contending that mussels generate a nutrient that is the main food of the bottom sea fish. Therefore, mussels have a positive impact on the population of deepsea fish; however, they may have a negative effect on the population of plankton eater fish, but the overall population of fish will increase.
