How a change in the size of the walleye pollock population affects the moon jelly population

The Interconnection between Walleye Pollock and Moon Jelly Populations

Understanding the intricate balance of marine ecosystems is essential for maintaining the health and sustainability of various species. One interesting relationship to explore is the impact of the walleye pollock population on the moon jelly population.

Walleye pollock, a key species in the Bering Sea ecosystem, serves as a primary food source for various predators, including moon jellies. These moon jellies, also known as Aurelia aurita, thrive in marine environments and their populations are closely linked to the abundance of walleye pollock.

Factors Leading to an Increase in Moon Jelly Population

So, how could a change in the size of the walleye pollock population cause an increase in the size of the moon jelly population?

How could a change in the size of the walleye pollock population cause an increase in the size of the moon jelly population?

There must have been a change to the birth rate or the death rate in the moon jelly population. Within a population, organisms are always being born and dying. If there is an increase in the availability of food, such as walleye pollock, it can lead to a boost in the moon jelly population.

When the walleye pollock population grows, it results in more food resources for their predators, including moon jellies. As a result, the moon jelly population can experience a surge in their numbers due to the abundant food source.

Furthermore, the relationship between walleye pollock and moon jellies is part of a larger food web in the marine ecosystem. A change in the walleye pollock population can have ripple effects on other species, such as zooplankton. These small organisms are a vital component of the marine food chain and are also consumed by moon jellies.

Therefore, a decrease in the walleye pollock population can lead to a decrease in food availability for moon jellies, resulting in a decline in their population. On the other hand, an increase in walleye pollock can sustain a higher population of moon jellies by providing them with ample food resources.
