Bottom Composition Matters, Underwater Cameras Can Help

As a pro angler, I use my Lowrance electronics every single time I am on the water. They are great at locating fish and structure, but when combined with my FishSens SondeCAM HD Underwater Camera they can show everything. A camera is a great tool for someone who wants to better understand what they are seeing on their electronics and for me, it helps get a clear picture of one of the most important things in bass fishing: bottom composition. Hard Spots Hard bottoms are usually the best, and bass will relate to hard bottoms of different types depending on the region. My Lowrance StructureScan will show hard bottoms as bright, white areas on the screen where softer bottoms will be more grayish.

Targeting Spawning Bass: Are They Going to Bite?

This time of year, anglers all over are fishing for bass they can see in the shallows. Some bass will be easy to catch and some are nearly impossible, like those that are in the act of spawning instead of just guarding their beds. There are a few things that I do to determine if the fish is going to bite and if they are worth spending time fishing for. Locating Bedding Bass One of the best ways to find bedding bass is to cruise the shallows with your trolling motor at about 40 or 50%. I have found that this is the best speed to both cover water and avoid spooking fish. Anything faster will scare fish away long before you get to them.

Researchers Find Link Between Climate Change and Gastrointestinal Illnesses

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.
