TPO 26 - The zebra mussel, a freshwater shellfish native to Eastern Europe, has long been spreading out from its original habitats and has now reached parts of North America. There are reasons to believe that this invasion cannot be stopped and that it poses a serious threat to freshwater fish populations in all of North America.
The reading and the lecturer are both about the invasion of zebra mussels to North America which is considered unstoppable and can cause a threat to native fish populations. The author of the reading provides three reasons to support this matter. However, the lecturer argues those ideas as he believes that they are not true.
First of all, it is established in the passage that the invasion cannot be stopped owing to the fact that zebra mussels can spread to North America by living in the ballast water of the ships traveling from Europe to North America. This idea is challenged by the lecturer. His position is that the invasion can be stopped when ballast water is removed and replaced by ocean water before ships enter North America. He also mentions that salt water can kill the mussels.
Secondly, the writer contends that these mussels can dominate the new habitat owing to their high rate of production, good adaption ability and the lack of natural predators. In contrast, the lecturer disproves this by saying that predators like birds are able to change their habit quickly to eat those mussels when they are abundant in the water.
Lastly, the reading suggests that zebra mussels who are plankton eaters cause the decline of overall fish productions in the habits they are dominant. The article notes that these mussels compete for food with other fresh fish. The lecturer, on the other hand, rebuts this assertion. He puts forth the idea that the presence of zebra mussels also provides positive effects on some other fish populations like bottom eating fish.
