Question
Inheritance of Traits
Humans have been shaping the traits of organisms for thousands of years. The methods for changing desirable traits have evolved as new technologies have become available.
In the aquaculture industry (fish farming), fish are selectively bred to have desirable traits in order to be more profitable. Desirable traits such as quick growth, resistance to disease, efficient feed-to-growth ratio, ability to tolerate a range of environmental conditions, and high meat yield are all characteristics that are selected and bred for. Sometimes, fish are genetically modified through gene editing to have specific traits. Selective breeding and genetic modification have evolved the genes of many fish species over time and caused a decrease in the genetic diversity of many fish species.
One of the ways fish are farmed is by creating enclosures in the open ocean where fish are grown and collected. These fish are often non-native to the areas in which they are farmed. Various drugs, herbicides, and foods containing non-native fish meal, fish oil, and fish eggs, are often added to the water in the fish enclosures. The diagram shows many of the environmental risks associated with this type of aquaculture.
When farmed fish escape from aquaculture settings, they can impact the surrounding native species and ecosystems. This can cause increased competition of resources for the native species, causing organisms with the most beneficial traits to survive and reproduce. This process is known as natural selection.
Multiple Choice Question
Warmer water temperatures can lead to a higher spread of disease and parasites among farmed fish. Which best describes how this might impact the populations of organisms in the surrounding ecosystem?
A.
It will increase the populations because they will have less competition.
B.
It will increase the populations because they will have more competition.
C.
It will decrease the populations because they will be less susceptible to disease and parasites.
D.
It will decrease the populations because they will be more susceptible to disease and parasites.

The best option that describes how warmer water temperatures leading to a higher spread of disease and parasites among farmed fish might impact the populations of organisms in the surrounding ecosystem is:
**D. It will decrease the populations because they will be more susceptible to disease and parasites.**
Warmer water temperatures can stress fish and increase their susceptibility to diseases and parasites. If farmed fish become sick or die off due to these factors, it can disrupt the ecosystem and potentially decrease the populations of both the farmed fish and native species that may be affected by the disease or changes in competition for resources.
**D. It will decrease the populations because they will be more susceptible to disease and parasites.**
