The pigment was retained by 100% of the unmolted crayfish 35 days after treatment and by 65% of the crayfish 56 days after treatment. Crayfish which were induced to molt after being sprayed generally lost the fluorescent pigment during the molt. Mortality, (2%), due to the marking procedures was minimal.iv, 42 leaves.application/pdfen-USIn CopyrightLD5655.V855 1974.B7CrayfishFishing baitsThesis
