| The present study analyzed the reproduction of wild-caught Penaeus paulensis in relation to its molt cycle. The experimental design consisted of two treatments (continuous water flow and batch renewal) with two replicates. The stocking density in experimental tanks (1.50 x 0.96m) was approximately 7 animals/m², resulting in 4 males (23.9 ± 2.3 g) and 6 females (52.0 ± 5.5 g) per tank. Shrimp had their uropods cut for individual marking and female maturation was induced through the unilateral eyestalk-ablation. The intermolt period of females and males (17.4 ± 3.2 and 17.8 ± 4.6 days, respectively), number of days between molting and the first spawn (6.9 ± 2.8 days) and number of spawns in the intermolt period (1.4 ± 0.5), presented no significant... |

| This paper describes the latest developments on maturation and reproduction of Farfantepenaeus paulensis in captivity, with special reference to the studies conducted during the last decade at the Laboratory of Mariculture, University of Rio Grande in southern Brazil, aiming to improve the future outlook for a sustainable nauplii production of F. paulensis. Particular emphasis has been given on the reproductive cycle, ovarian maturation, maturation and spawning systems, artificial insemination, broodstock reproductive performance and maintenance of captive broodstock. |
