I would put off the fishing part of the date for now, so that you can do some reconnaissance work to find a good "fishing date" spot.
You wouldn't want to plan a fishing excursion and end up having her think that you don't know what you're talking about (because of poor fishing)?
I never hurts to stack the deck a little in your favor when dating.
As they say, "All is fair in love and war!"
By checking out a few spots beforehand, you can come off looking like a pro, and since you will have found a place that holds the most promise, odds are you will catch fish.
Remember, it's a lot like when you take a kid fishing for the first time: If they don't catch fish, they lose interest rather quikly, and if you are catching all the fish, it's over before it began.
Good luck
