Not for sure about the Jellyfish. If you caught two Flounder and they are keepers sounds like a good day to me. Keep at it and you will eventually bring them home. Try changing up your baits.I went out flounder fishing Judith Island yesterday (7/18) and saw a ton of jellyfish. Only caught 2 flounder on 3" pearl white gulp shrimp with 1/8 ounce jig heads. I cast right up to the grass and either slow retrieve or slow jig back to the boat. I was wondering if the amount of jellies affect the fishing? Or am I just doing something wrong?
