What makes the flea problem better or worse ....certain times of year ?

I am trying to learn the lake game and keep my kids interested. Only get out a dozen times probably and just bought a new lowrance hd elite 4. Here are a couple questions if anyone is willing to help. 1) I am literally not marking any fish .... Is this possible. I have marked bait balls and thermocline ( I think ) but no fish. 2) Was out today for a few hours and caught two small steelies. 3) when folks are talking about "other fish" .....as easier to catch.....lakers I am assuming .....what can I do different to catch something for the kids. I am running 2 riggers and 2 dipseys. Today ....3 spoons and one spin doctor. Speed around 2.3 and mainly between 200 and 400 feet right in front of olcott. Depth from 35-65. Lots of boats moving around so I'm guessing not a stellar day but who knows. Thanks for any ideas
