Seeing fish on the graph is exciting, seeing a lot of fish on the graph is very exciting....until you pull fresh lively striper candy through those fish without a single bite. Ive learned over time that im looking for two things on the graph, the first is fish AND bait on the same screen, fish eat bait, so generally speaking if theres bait around, the fish are feeding. The second thing, and the most important thing I want to see on the screen is action, lots of movement. You will often see the diagonal streaks indicating fish chasing bait up and shooting back down. When you see this I am going to assume with a great degree of certainty that these fish are stripers. I just dont normally see that level of activity with cats. Ive caught a ton of cats this year, more than I can ever remember, but ive never had multiple simultaneous hookups on cats, I have had every rod in the boat go down at the same time only to land one short striper, which is what Duayne was saying. If this happens I move immediately, you can waste a tank full of bait very quickly on the shorties, even if the dont get it off the hook they pull on the body and stretch the gills and now youre pulling dead bait. Another bait thief is the smallmouth, I cant count the number of smallmouths weve caught 60 feet deep in 100 feet of water, and see them on the screen and they look like small schools of stripers. The best way to see whats eating tour bait is to look at it real close....like in the net
