Sturgeons are “Black-and-White” Viewers
Yes, that’s right. Sturgeon fishes are kind of “colorblind” fishes in the sense that they see their surroundings in black and white.
So if you plan on having a Sturgeon fish pond, it might be a good idea to choose a white- (or light-) colored pond liner or “foil” for your Sturgeon pond and do not put a lot of dark-colored pebbles or gravel in it (in fact, it might be a good idea to try not “putting in” some substrate) so that your Sturgeons can easily see the bottom of the pond and “make out” the “sinking” food, which will have to be dark-colored in order to contrast with the light-colored liner or “foil”.
