Heat Wave - Magikarp - 06-20-2012 07:28 PM
Will deep water fishing be more active because all the fish will be in the deeper parts due to the heat? I mean the top layer of water will warm up but 20 feet down its probably still cool. any suggestions or ideas on the topic?

I'm interested in this as as well. I know that most pike will move into deep parts of the lake during the summer, inaccessible by shore. But that's about all I know.

I find that this year is quite strange as far as temperatures go. Went to Dunnville yesterday, targeted some catfish. Water was 28 degrees C, which to me is completely crazy.

This time of year I usually go at least 4 hours north and the weather is no where near as humid, and the mornings/evenings never disappoint. Honestly though, if fish are cold blooded then there is no reason for them to eat in this kind of weather (pure speculation on my part).

Alot of people say bass like to take to cover during heat waves,which is probably why it is the most caught fish by people in the summer.

well with the way the weather is chaining into next week its going to cool of by about 10 degrees or so so we will be able to note the difference between the 30s and the 18s area in temperature change come next tuesday

Well, I would see this as a reason for their metabolism to be more active. In the winter, I'd expect their metabolisms to be slowed by the cold.
Again, more speculation, but there's probably an ideal range of temperatures where they best carry out growth and repair.
I did some searches about it... this was the closest article I could find to answering my question:

Different fish has different metabolism...
Trout and salmon prefer colder water.
Bass and pike prefer cool water.
Carp and bowfin prefer warmer water.
Sunfish don't care either way.

So if we throw a fish into boiling water, would it die from exhaustion?
Lol just kidding, but like you said there is an optimum temperature, too high would result in lower enzyme activity, blood pH change, etc. I'm guessing that more food + more movement in search of food would increase the fishies body temperature even more, which is bad.

Don’t forget that the oxygen content of water is inversely proportional to the water’s temperature.
This fact is one variable that drives a fish’s “comfort zone” as well as its corresponding level of activity.
In a lake, fish can go deeper to find a comfortable temperature with suitable oxygen levels. Their finned prey will do likewise which further prompts the move.
In a river, fish do not have this option, so they will adjust their activity to the times, and the feeding opportunities that take the least amount of effort.
