Increases in sedimentary and algal turbidity are likely to result in altered underwater visual environments. We investigated the effect of these turbidities on the ability of two fishes, emerald shiner and walleye, to detect contrast underwater. Our findings suggest increases in suspended algae compromise vision more relative to sediment.
