There may be more reason on why Ohio's game fish, such as bass, walleye, crappie, etc. are not as big in Ohio as they are in surrounding areas. The growing season each year, or when the weather is warm and fish are feeding the most is shorter in Ohio than say Kentucky or West Virginia. However, it is not shorter than Michigan, or even Canada. Yet, when you go up north you tend to get better fish populations and larger numbers of large fish which is what makes Canada so popular. I'm not sure if any of you have ever considered this, but acid rain could be the cause of low or declining fish populations. Check these numbers out: Natural rain acidity is 5.6 on the pH scale (7 being neutral, anything above 7 is a base, below is an acid) A level of 5.0 affects fish reproduction. 4.5 is leathal to fish. 4.4 is the average for the northeastern part of the United States. Ohio is completely covered by the area that is in the 4.6 average. The areas outside the Indiana, Kentucky and W. Virginia borders area affected very little. Just thought I'd share this with you......just a little deduction I made based on information in one of my classes.
