This material addresses the questions of whether the zebra mussel's invasion to North America might be stopped, and whether this fish would dominate in their new habitat.

This material addresses the questions of whether the zebra mussel's invasion to North America might be stopped, and whether this fish would dominate in their new habitat. The reading passage suggests three arguments in support of the view that the mentioned fish population will increase and that this fact might cause other fish population to decline. The lecturer, on the other hand, refutes this information by stating that there are efficient ways of control and that zebra mussel's penetration to North America might not inevitably cause reduction of fish population out there.
To begin with, the reading passage highlights that zebra mussel spread is unavoidable as it is brought by the ships traveling from Eastern Europe to Europa and after that to North America. Meanwhile, the professor casts doubt on this and argues that this can be controlled, if the ships refill the ballast water by ocean water, which will kill the fish.
Additionally, the article posits that once in the new habitat, the zebra mussel would dominate there. However, the professor advocates a different approach and provides the following details. Namely, he mentions that predators might appear in the area and prevent possible domination.
Finally, the author invites attention to the fact that this fish will be a cause for a decline in the population of fish in new habitats, as zebra mussels eat plankton - the food of other fishes. This goes counter with the information in the listening passage, according to which, only some kinds of fish might decrease in number, while some other types, which does not eat the same food as zebra mussels, would increase in number.
