Ice Fishing With A SondeCAM Underwater Fishing Camera

Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.

Size Them Up With A SondeCAM Underwater Fishing Camera

We've all felt the frustration of weeding through a school of dinks to catch a "keeper." Often the small fish outnumber the bigger ones and they are typically more aggressive. Sometimes there's no choice but to deal with it, as is often the case with open water fishing. However a frozen lake involves a vertical presentation and a stable platform, it's a perfect situation to pick and choose which fish you want. Once you locate a school and get set up it's time to start sizing them up with a FishSens SondeCAM underwater fishing camera. It can be mind-blowing just how big some of these schools of fish are and also how outnumbered fish of a desirable size can be.

In Ontario Lakes, Non-Native Bass Impact Native Fish

It’s no secret that anglers have been the means by which invasive species and non-native fish have spread to new water bodies in the past. Fishermen have even been known to transport some of their favorite fish to new areas on purpose so that they can catch them a little closer to home. And the results of those actions have not always been ideal. In Ontario, Canada, fishermen have taken non-native bass and stocked them into what were historically lakes dominated by brook and cutthroat trout. The actions have impacted ecosystems, but scientists have been unable to broadly study the effects because they didn’t have enough data. But that is no longer the case for some Ontario lakes, as a study from biologists at the University of Toronto shows.
