Newly hatched larvae of silver carp Hypophthalmichthys molitrix were fed fluorescent latex microspheres 5, 10, and 25 μm in diameter over an 80‐h incubation. No spheres were observed in the gut region until 72 h posthatch, and larvae appeared to prefer smaller spheres at 72 h. This technique may be a useful tool in establishing the onset of particulate feeding and in the study of early feeding behavior.
