To satisfy the needs of shrimp farms of southern white shrimp Litopenaeus schmitti in Cuba, an increased mating success of pond-reared broodstock is needed in commercial hatcheries, and this objective depends mostly on the quality of males. Even though this species can reproduce in a closed life-cycle, batches of low-performance pond-reared males have been obtained. To analyze whether the system of tanks is partly responsible, in a first experiment, reproductive performance was compared in unisex and mixed tanks during a production period lasting 28 days. In a second experiment, reproductive performance, sperm quality, and physiological condition was compared between pond-reared and wild males throughout a production period of 70 days. In the first experiment, reproductive performance of mature females, mating success, fertilization rate, number of nauplii, hatching rate, and survival for both sexes did not differ between systems. Additionally, mating success increased significantly th.....
