I've been playing Stardew Valley for a while now and I've learned the pain of having to check the wiki every time I need to confirm things for the fish bundle. So I copy-pasted the wiki and changed the format some and colored-coded it! It even has a little spot for you to put the save you're using so you know how far along you are for each.

Two long, cold, windy days fishin with clients and only saw a few muskies. No hook-ups. These are hard days guiding because you feel guilty charging someone for just telling stories of how "we got one here", and "I nailed one there."

Tarpon season in full swing across SWFL

@gnarzknoedelbloeh I figure a visual aid would be easier than me describing my favorite fishing locations.  You probably know this already but not only different fish spawn at different times, one needs to use bait to lure a bunch of the rare fish out.  Sharrac and Karkina need Twilight Bait, Murkray needs Murkray bait, and Norg needs Norg bait, etc.  I think some people believe that certain fish spawn more around dawn or dusk, but I haven’t tested that extensively.

A note about Mortus Lungfish.  It actually does spawn during the day but it’s pretty rare so better you look for that fish at night instead when it’s super abundant.

Technically, you should be able to catch the sea fish on any of the coast lines east and west of Cetus, but the part I circled is my favorite spot.  That little island is great for avoiding enemy (especially during the infested boil event).

For more detailed info, check out the wiki.

If it’s too much trouble fishing, you can always trade with other players to get the fish you want. XD
