IMO, your site has a number of "distractions". My first impression of it is that it is too "busy". My eyes couldn't focus on any one thing (other than the girls in the background for a few seconds). Your background image takes away the attention from what should be the most important aspect of your blog... the content. If it was my site, the changes that i would make would be:
Change the background image to a simpler one (by simpler i mean a single colour or something that doesnt take the focus off the content)
"Less is more" a famous saying that can be implemented into the blog. By this i mean ads. there are too many ads and not "blended" in. (change the top level google ads to a similar colour as the menu for increase in CTR and maybe have a few less sidebar ads and maybe an in-content ad block; I don't know if you have already as i am just on home page first impressions)
Have a dedicated page for the pictures of fishing models and again, NOT as a background image.
I can go on for more, but this is the basic stuff what i would do to start off with and with that, you should see some improvement (assuming you have good targeted traffic leveles etc etc).
My MAIN piece of advise would be look at your target audience. Do some market research and see who these people are and build a sort of "avatar" (an imaginary person that is a member of your target audience) so that you can relate to this person's needs and questions and then answer them in your blog.
Hope this made sense, i could go into more detail, but one thing at a time.
