While there will be a few fish caught in april...the real "run" doesn't begin until mid may (IMO) and really kicks in high gear around the 1st of June IMO. Even then it is not as great as the fall run.
Unless you want to run around and break in your new boat (which is a worthy excuse to get out there!) ...the fishing here is pretty slow in april...yeah...a few flounders/cod/perhaps a tog will be caught....but the bass like 50 deg water...currently the water temp 1 mile off the MV beach at the bottom is: 33.3 deg F.....relax the bass have not even spawned yet, they are still sleeping.

IMO instead of fishing, I will be preping my equipment the next couple months.
But I always start late and end late (for bass)....My first day of fishing last year was late may and my last day was early Dec.
IMO the worst time to live in NE is early spring...the rest of the year is great.
