Polychaetes and the semi-moist formulated feed were the greatest contributors to the shrimp fatty acid profile, particularly fatty acids of the n-3 family. Biofloc systems, whether pond or tank based, represent a management practice that permits intensive production of juvenile shrimp under efficient and sustainable practices. Stable isotope analysis affirmed the nutritional value of natural productivity (bioflocs) for juveniles. Biofloc- derived nutrients persist in mature broodstock and are combined with other nutrients, specifically n-3 fatty acids from particular food resources, which are transferred to eggs and positively contribute to fecundity and hatching. These results can serve as a foundation for guidance for management practices that consist of the most effective combination of formulated feeds and BFT to yield the best possible nutritional sources (size and composition) for growth and pre-maturation. In addition, the application of the results derived from the study of isotope signatures of foods that make the greatest contribution to the composition of spawned eggs should help in realizing the goal of achieving exceptional reproductive performance. — Louis R.
