Struggling to catch tuna in stardew

Ocean, summer or winter, between 6am and 7pm. It's one of the harder fish because it darts around, so the bar keeps slipping off it. What made it doable for me: the cork bobber for a bigger bar (or trap bobber once you have the iridium rod) and eating something with a fishing buff first. If your fishing level is still low, honestly just come back in winter after a few more levels.
