Raymarine for marking small feeding baitfish.

Posted on October 26th, 2015

I really appreciate the accuracy of my Raymarine fishfinders not just for marking bottom and fish, but also enabling me to understand the size of fish and their activity. This is important when you are trying to find active fish that will strike.


I wanted to show you this screen-grab from my recent smallmouth/walleye fishing trip on the Lower Niagara River. As you can see on the Raymarine DownVision side of the screen the “cloudy” looking mark on the bottom is a large school of small, feeding baitfish. How do I know they are small? If they were larger the Raymarine fishfinder would actually show the baitfish as individual marks. These baitfish are under 1 1/2″ in size and to confirm that, some of the smallmouth we were catching were regurgitating them! How do I know the baitfish are feeding? They are dispersed over a large area and the “cloud-like” mark is not dense. That means they are preocupied feeding on organisms just off the bottom. If they were not feeding and being predated upon they would be in a “ball” configuration and very tight together in a defensive position.


I guess you can my Raymarine fishfinders are my underwater “guides” helping me not just to mark bottom and fish, but giving me a really good understanding of what the fish are doing!
