Control of Apus and Fairy Shrimp in Hatchery Rearing Ponds

Single applioations of 0.25 ppm Dylox effectively controlled the tadpole shrimp, Apus longicaudatus, and the fairy shrimp, Streptocephalus texanus, in hatchery ponds without adverse effects on bass or channel catfish fry. Bass survival in treated ponds was boosted from 20 to 80 per cent by the Dylox treatment. Plankton populations in the treated ponds appeared unaffected.
