It’s a big ocean. That’s what you’re up against when you’re trying to find albacore tuna. You likely have to travel vast distances which cut your fishing window down. The trick is to identify where the tuna are before you even leave the dock.
There’s multiple ways to do this. One of them is to have good solid reports or a network of friends to tell you where the tuner are. Another way to do this is to sign up for a website that will give you chlorophyll and sea surface temperature readings (e.g. Terrafin.com). Then what you do is look for brakes in the sea surface temperature usually when the temperature gets up to about 65° and climbs a couple degrees all at once then this could be an area where you would find tuna. This give you a place to start trolling. Then as you troll, you watch the sea surface temperature on your sonar unit for breaks. Also, you can watch for birds and jumpers. Or leverage the technology in most newer radars (called bird mode) and watch for birds with your electronics.
