Of all the fish in freshwater ecosystems, there are few as important as bluegills. Yes, this is a bold statement, but I say this because bluegills (other sunfish species) are the engines of many North American aquatic food webs. Think of how many zooplankton a bass would need to eat to get the energy found in one sunfish. You may have fished a bass pond without many forge fish (aka bluegills or some other small fish species) within it, and you’d likely caught larger bass that are stunted, skinny, and jaunty. Bluegill and sunfish serve as the much-needed bridge between zooplankton and larger fish in the aquatic food web.

Winter can be tough for any animal, but it seems especially so for freshwater fish. Trapped under the ice, with little food, plant growth, and oxygen make lake life in winter a seemly destitute environment. So how do fish in lakes and ponds survive? As it turns out there are four main factors that fish need to overcome to survive harsh winter Including:
1. Thermal stress
2. Starvation
3. Predation
4. Disease
If a fish can overcome these four factors and oxygen depletion (which we are not going to cover in this article), their likelihood of survival over winter is pretty high. We will cover each of these four topics in this article.
