A good friend of mine from my years as a photography student at the University of Wisconsin Milwaukee is doing her thesis this semester on a topic that she and her family has been involved with for quite a number of years now. She has created a blog doccumenting Sturgeon spearing on Lake Winnebago in Wisconsin. Steph has "been around sturgeon spearing since [she] was born" and as a photographer who I have a good deal of respect for I expect great things from this project.
Have a look at what has started out to be a promising project, and as the season begins get ready for some great photography. You can check out her blog here : Winnebago Lake Sturgeon.
