the zebra mussel
Both the author and the lecturer discuss whether the zebra mussel invasion to North America causes a serious threat to freshwater fish populations. The passage claims that the zebra mussel spreading poses a serious threat to freshwater fish populations in the whole of Europe. The professor, on the other hand, reject what mentioned in the reading through citing three reasons.
First, both the author and the professor talk about unstoppable invasion. According to the passage, the zebra mussel invasion cannot be stopped. For example, they spread by human transportation activities to the whole of Europe. The lecturer, nevertheless, rejects the author's view and illustrates the idea that people did not have enough knowledge in the past but now they can stop transferring fishes to new locations. They can replace ballast water with seawater, which is fatal for this creature, in halfway of the journey, so they get rid of the zebra mussels.
Second of all, both the reading and the lecture discuss the domination of the zebra mussel in a new habitat. The author argues that these species are very compatible with different environment condition, so they have a high rate of reproduction. However, the professor refutes this, saying that it is true only in the beginning of immigration. For example, when this species entered to a new place birds started to change their food habits and ate the zebra mussels, so they have predators to prevent their domination.
Eventually, the passage and the lecture address the subject of the change of overall fish population. The passage goes on to mention that overall population of freshwater fish reduces where the zebra mussels become dominate. In contrast, the professor points out that not only does not the zebra mussel have negative impact on other aquatics but also it has positive effect on bottom-feeding fishes. The zebra mussel provide bottom-feeding fishes with nutrients that increase their population.
