The lecture and reading both discuss Eastern Europe of the zebra mussels spread in North America. The author believes that constant widespread of zebra mussel in North America was unstoppable. It gets the negative influence on fish population. The lecturer casts doubt on the claim made in the article. He thinks that all points of the author are dubious and now possible to control spreading of zebra mussel in North America.
First of all, the author implies that human migration may responsible for invasion of mussel in North America. He states that mussel adhere to ship bottom and easily survive by ballast water. This point is challenged by lecturer. He says that in past, it was true that cannot control the invasion of mussel because of lack of knowledge. However, in present number of ways found to prevent spreading of mussel. For instance, ship travel from Europe to North America, that time ballast water fill in ship but ship could empty after to reach in North America and refill by salt water, in salty water mussel cannot survive.
Secondly, the author emphasizes that zebra mussel dominant in new habitat because of no predators and high rate of reproduction. The lecturer rebuts this argument. He mentions that in beginning of new habitat area has no predator but after native birds seek new food. New food replaced old food and birds eat huge amount of mussel, therefore, mussels were no longer dominant in new habitat.
Finally, the author states that zebra mussel eat plenty of planktons resulting decrease the overall population of fishes. The lecturer, in contrast, points out that mussel habitat not negative effect on fish population. He elaborated on this point by says that mussel has positive effect on bottom sea fish because planktons eat by mussel's and they provides lots of nutrients in water which sediment in bottom and feed by larger bottom fishes. Even though decrease the planktons, increase the larger bottom fishes.
