macrophytes may be limited by water clarity or water depth. High macrophyte coverage means more shallow water. Deep water serves as a refuge for large zooplankton during the day, they migrate to avoid fish predation. With out a deep water refuge the large zoops. and cladocerans might not survive. The diffrences in the lake morphology may create diffrences in the zooplankton community that inhibit gizzard shad survival.
Macrophytes may also increase predation on age 0 shad, or inhibit foraging behavior. Forcing age 0 GS to live in close contact with adult BG may increase BG predation on YOY shad.
Excellent points!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
