My fisher turntable has a red and yellow jack but my speakers have a red and black slot for wires

Solution
Any Fisher turntable will require a phono preamp. You will need one either external

or built into an amp or receiver. Since you need an amp anyway to drive the passive speakers you describe getting a built in one might be cheaper. Most older stereo receivers and amps will have a phono input. Some new ones will too.
Black-and-red speaker connection means this is dump (non-powered) speaker. You need a stereo amplifier with turntable support (PHONO input) between the turntable and the speakers.

And as @jsmithepa mentioned, you have to check whether your turntable has built-in RIAA correction.
