Morphology
The compound simply names a bar-like structural element associated with gills: combining 'gill' (breathing organ) with 'bar' (a rigid piece) yields a support structure for the gills. Although somewhat technical, the meaning is compositionally predictable and mirrors cross-linguistic constructions (e.g. 'gill/gill-arch'), so a B1 learner who knows both constituents can infer the sense.
Etymology
Gill bar The noun gill bar names the small bony or soft bar under a fish's gill that holds the thin breathing parts in place. Picture a tiny rib or shelf that keeps the gills open so water can flow and the fish can breathe, so gill bar simply means 'a support for the gill'.
