Description:
Maturation, mating, and spawning of pink shrimp, Panaeus duorarum, are described. hree temperature cycles over 130 days produced three separate periods of maturation and spawning within 7 to 14 days after the water temperature increased from the minimum of 20.5 +/- 0.5 degrees C to the spawning temperature of 28 degrees C. iable eggs (83 to 97 percent hatch to protozoa) were obtained in all three temperature cycles. urvival of shrimp from egg to post larvae fed unicellular algae, Isochrysis galbana, Tetraselmis chuii, or the diatom, Chaetoceros gracilis, and combination rations of I. galbana with T. Chuii or Skeletonema costatum suggests that II galbana is inadequate as a nutritional source for pink shrimp, the greatest survival (83 +/- 3.2%) was obtained with the diatom, C gracilis. uring the first two months, post larval grew, on average, from 0.072 mg to 109 mg.
