There isactually a method coupled with sound physiological reasoning to “the bite.”
Some may call itnatural conservation of energy. It’s based on digestion that is regulated by oxygen availability in environmental water. It requires a lot of oxygen for digestion to function properly in cold blooded fish and 85 F - 90 F water contains far less dissolved oxygen than colder 70F F water.
Those DogDays of Summer are definitely coming again like the flu season and those hottest days of the year coming again soon are as predictable as the rising of Sirius, the brightest star in the night sky. Sirius rises again 70 days from today.
How Water Temperature and Oxygen Affect Fishing https://www.mistertwister.com/twister-tips/article/how-water-temperature-and-oxygen-affect-fishing/417
There’s no simple answer to the question, “Why do fish bite?” Many variables are involved. *Two of the most important conditions dictating fish feeding activity are:
1. Water Temperature
2.Oxygen Content
However warm water does not contain much excess oxygen, which fish need. When it gets too warm and oxygen levels drop, fish become sluggish and inactive.
Favored Temperature Ranges
Listed below are the favored temperature ranges where digestive systems function best,and the oxygen content is high enough. Usually,the best conditions exist in the middle of the range.
Crappie 65 F– 75 F… best water temperature is 70 F.
The hotter the water the slower the bite, the Dog Days of Summer is the hottest environmental water temperature in the America.
When are those Dog Days of Summer 2020 coming again?
Farmer's Almanac lists the traditional timing of the Dog Days: the 40 days beginning July 3 and ending August 11, coinciding with the heliacal (at sunrise) rising of the Dog Star, Sirius.
